I agree with you but they won't do it due to the Cafe standards the government set up for mpg of vehicles. Thats really the issue they try and get the trucks more fuel efficient and it causes more problems than it fixes. It is a truck and people who buy trucks for the most part I think understand that you will not get 40 mpg out of it lol
That AFM in vehicles with 8-speed autos has been causing transmission shuddering in some vehicles when going into V-8 to V-4 mode. GM. changed the transmission oil specs which helped out quite a bit.
I'm a former Chevy tech and I cannot tell you how many of these lifters I've replaced. I've replaced lifters, pushrods and lifters, and lifters, pushrods, and camshafts. The lifters either get stuck expanded or stuck closed and either bends the pushrod or just causes a misfire. Job pays 9 hours to do one bank or 11 for both banks but we were doing so many of them, we were able to knock out 1 bank in about 2 hours. I've seen 2020-21 trucks/SUVs with only 1800 miles in them. Really sad.
@@Mr-ow3mk doubt it. The lifters that GM are using to replace the factory lifters are junk. Just replacing junk with junk. The lifter guides are plastic, should tell you everything you need to know
@@dylanlikeavillan5165 so these are with the new LT motors? So if I decide to put one of these motors ( truck version) in my Camaro that's what I have to look out for ?
@@Mr-ow3mk I am not really at liberty to speak intelligently on gen V as I am still on gen 3-4 land bit as far as I know all All LT1, LT4, L83, and L86 engines include AFM, LT5 does not have AFM crap. They have also introduced another variety, dynamic fuel management (DFM) another acronym yay! It has all 16 valves on springs, yuck! G.L. with the Camaro swapin
I had a 2015 Sierra with the 5.3l. I ran it up to 150k miles in just 3 years and had tons of issues with the engine. Multiple trips to the dealer, then after the warranty, multiple trips to the local engine shop. No one figured out what was wrong with the truck. Then one day I was road tripping it, I had the oil changed the day before and I know the engine oil was full and the low engine light came on, and that was it. Only 1000 miles on a fresh oil change and the thing was low on oil. I had always that issues since my first oil change at 5,000 miles a the dealer. It never leaked. That 5.3 made a rod pop out the side of the block. That was that, I sent it off to the junkyard. I have since purchased a 2006 Silverado 5.3 it had 15,000 miles on it in 2018. Now it has 165k miles on it, and I have had zero engine issues with that truck. I wouldn't buy any GM engine that has active fuel management. I'm sitting here wondering if I can recoup any of the money I put into my 2015. If not, I hope you guys win this lawsuit.
That stinks Nate. Sorry to hear about all those issues. That's incredibly frustrating. The only way to really deal with it is to delete afm fully. 2006 and older is simpler which usually = better
@@TheSundaeDrive That's why I went and found the cleanest and low mileage 2006 GM truck I could. Been very happy with it. I've often wondered if I deleted AFM day one on my 2015 just maybe I wouldn't have had issues.
The very reason, if it's going to be a new vehicle. Honda or Toyota ONLY, the new American vehicles are unreliable and European vehicles are over engeered plastic garbage. Wife's car is a 2010 Toyota camry, the daughters car is the old family beater/spare 1996 Toyota corolla. My car is a 1989 Honda accord. Also we have my 86 5 speed square body ford ranger and the her 1995 Subaru wrx. All of the car have no emissions systems to speak of except for the 2010 camry. They have not failed yet, so no need to rip it out and tune it to run with out cats yet.
@@elyk1996 really lucky find from a old person or a barn find. When I bought my current farm I went into one of the back barns and that's where I found my 86 ford ranger.
I literally had a lifter collapse today in my 2017 GMC sierra with 62k miles. I will be calling the dealer tomorrow to see what they can do. The failure at 62k miles and a clean service record is ridiculous!
Being a dealer tech, I've seen them go on 2021 5.3 and 6.2 as early as 1000 miles. And after we replace them, a few come back 3000 miles later for the same thing, replacing junk with junk
If you are out of the powertrain warranty (i think gm shrunk it to 60K) they will still normally cover a large portion of the repair if not all of it since you are so close and the truck is so new
@@TheSundaeDrive 42k on my 2015 and it just gave out sending metal all through it no warning. trans was crappy from day 1 brought it back several times and was always told operating as designed. 3600 bucks later its rebuilt still has some weird shifts from time to time. I will say HP tuners has helped quite a bit especially with the TCC lockup speeds and slip.
This is a great example of how Manufacturers’ engineers actual knowledge and quality control have gone out the window in favour of bells and whistles that are unnecessary and troublesome in themselves.
This is a great example of a lawsuit that makes no effort to differentiate actual defects from GM and cases of lifter failure due to owners with room temp IQ's that don't change their oil often enough, don't check their oil level, add so much oil it causes oil aeration, drives short trips all winter long and causes the oil level to increase due to the amount of unburned fuel that's diluting the oil down and causing wear, etc. If your lifters made it 100k miles and then later fails, that wasn't because of a defective lifter, that's a case of an owners that joined the "I change my oil ever 7500+ miles cuz I buy the good stuff" when their DI engine has been loading up that oil with diesel-like soot and unburned fuel for that entire interval and has caused wear and sludge formations that cause lifters to malfunction.
I used the Range AFM disabling module on my 2010 5.3 Silverado and it literally saved the engine. The #1 & #7 cylinder plugs would foul and this started under warranty. GM would perform service to mask the problem and get you through warranty. The truck started using oil too. I discovered the Range AFM module and drove the truck to 230K before trading it in. Plug fouling stopped, oil consumption stopped as the engine cleaned itself up. I transferred the module to the 2018 Silverado I purchased also with the 5.3 so I’m hoping for the same long term results. I wouldn’t drive the GM product without disabling the AFM it’s junk!
Don't leave that thing plugged in if your not driving every day. Replaced 2 batteries because of that device. It's great but puts a slow constant draw. I think I'm just going to get a tuner because they can disable afm and don't have to be plugged in. Also don't unplug that thing after the engine is running. My truck stayed in 4 cylinder mode during idle and was running like crap, couldn't even drive it because it wouldn't go to v8. Luckily I disconnected the battery and the computer reset, all has been good since.
I used the Range AFM disabler on our 2018 Cadillac Escalade 6.2. Worked awesome.... the lifters sometimes would tick louder sometimes before the Range Afm disabler. After quiet all the time. I also used Royal Purple oil as well!
thanks for your reply. I bought the Vet new in 2017 installed the Range a month later so far so good it now always stays in 8 cylinder. Enjoy your ride, nothing makes me smile more than a full tank of gas & 8 cylinders running! keep smilin
Never again. They've lost a lot of folks for good with this insane complication and aggravation by over-engineering the reliability and serviceability out of their vehicles.
Been a Chevy guy since the 60's. I sold my 2010 Silverado after it started having issues. Glad I did also. Not completely out of the GM arena as we are driving a 2015 Traverse. No issues with it. Nice little car.
I want to ask the gm executives a simple question. Why do you insist on chasing this rabbit down its hole. You've known since 07 that this design is extremely flawed so why not just do away with it already. People dont buy trucks for good gas mileage. The same goes for sports cars so just eliminate the AFM from your V8'S and sell your products on reliability rather then fuel economy. I've been a die hard chevy man for a long time. I'm currently looking to buy a new truck but I'll be dammed if I spend 70k on a truck that's going to have major engine problems before hitting a hundred thousand miles... it makes no sense as a consumer and has me leaning towards dodge as an alternative to my beloved chevy. I don't think I'm alone in this. Gm needs to rethink there position on vehicles.
@@TheSundaeDrive yes sir. I'm a diesel mechanic and none of the epa regulated technology works the way they claim it should. Nothing but problems with it but at least in this case were not talking about catastrophic engine failure. The dealership limited the carbon emissions to the exaust and external parts. GM just keeps repeating the same failure over and over at the cost to the consumer. At least try something different. What they're doing is infuriating.
My 11' WT 4x4 with the 4.8 has 253k and it's been amazing. Replaced 1 motor mount, shocks & struts, front hub bearings, brakes, tires and 1 blower motor. I put a corvette servo in the trans at 230k to help hopefully get it to 300k. It runs and drives fantastic...friends and neighbors who borrow it can't believe it has the miles it does and that WT interior with the rubber floor really holds up over time. It's not a powerhouse by any means, but it scoots pretty good unladen and has pulled anything I've hitched to it without too much drama. I'm perfectly happy with this thing and would keep it forever, but I'm in the upper midwest and rust is starting to bubble up on the bed. I know in 2 years it's going to look like garbage and while I don't mind some well-earned patina, I can't stand rust. I know I'll need to replace it soon, but I'm really not looking forward to the inevitable tech that newer trucks are laden with. Based on experience with my current truck, GM has earned my business on the next one but I'm not gonna lie...I'm terrified. I spec'd a 21' WT online this morning and it doesn't appear that the manual transfer case is still available? I can't spec the locking axle without adding the Z71 package? I knew my beloved hand-crank windows were long gone but I figured I'd still be able to mostly have it my way. I'm going to ease on over to the Ford site this afternoon to see what their idea of "stripped down" is these days.
Glad to hear it has been holding up well for you! Hopefully it gets you to 300K. I don't think there are any manual transfer cases anymore sadly. Stay away from 19-22. Hopefully by 23 they fix the lifters.
I wanted low range in the transfer case. Backing a loaded trailer in soft conditions means smoking a transmission or clutch without it. You have to buy the offroad package of some kind to get it. HDs come standard with it. Buying anything other than fully optioned is a nightmare experience. Right now, from each manufacturer's website, Ram offers the most truck for dollar. Ford is the most money.
@@thegreenerthemeaner I spec’d all 3 yesterday as base model v8’s with only the necessities and you’re right…the Ram was lowest, GM in the middle and Ford at the top. I tend to keep them 10 years and pile a lot of miles up…does a Ram have the longevity? My Son has a 15’ with 170k that needed an entire valve train & cam overhaul @ 160k and it seems like I don’t see many in the 300k range that still look and run well. For now I guess I’ll keep ol’ Betty White for another year and revisit this exercise then.
I replaced the lifters and cam on my 08 gmc because #7 lifter got stuck. I ended up dod deleting it and had a street tune. The truck ran great after that. I gave it to my son, he drove it for 2 years and sold it. He bought a 2014 chevy z71, i told him to go have the afm or what ever it's called deleted because it's just a matter of time. It only has 50,000 miles on the 2014 and he has an extended warranty until 100,000 miles, hid deductible is only $100
I always wondered how they weren’t sued before when it came to these AFM. EVERYONE tells you to delete these things before you do your ls swap. It wasn’t a matter of if they would go bad but when
Thanks for the info. While I was out leading a Jeep ride yesterday my wife bought me a truck as a surprise. It’s a 2016 and I had no idea what any potential problems would or could be. I watched your other video and BAM! It was all right there. Thanks for keeping people informed.
Thanks for the information. I have a 2014 Silverado with only 50K miles (hunting and boat towing mainly). Besides frame rust, AFM failure is always on my mind. My game plan is to change the oil with no less than 25% life in order to keep crude out of the AFM system. Maybe if they win this suit, there will be a recall. The next concern will be that the recall fix will be worse than what I have now. Thanks again, you have a new subscriber. Joe
I owe a silverado 6.2 and at aprox. 10,000 I did dod delete thru the pcm. I changed the oil at every 5000 miles or 30% of oil life and still at 95000 my lifters collapsed.
Yeah, what's up with the frame rust????? I bought a 2015 in 2017 with 30000 miles on it and I had all sorts of rust already on the frame. Took it to the dealership and they're like we don't worry about rust in the south, but once they saw my truck frame there like "ouch!!"..... we'll take care of that
@@jimmyboy163 whatever you do don't get ziebart! I bought my 2014 two years old. All of the factory wax was coming off. I scraped rust and did rattle can undercoat and fluid film. Couple more years go by and OMG. I live in salty update NY. Thought maybe ziebart. Big mistake. I had it on a few years this fall I was under the truck taking it all off. It wasn't that hard. It cracks and water and salt get behind it. I used rattle can Rust-Oleum rust reformer and Rust-Oleum paint and fluid film all over and in the frame rails. It looks good. It is a constant battle. I only have 50K miles so rust will eventually win. Joe p.s. if you go at it get a needle scaler from harbor freight and a welding slag hammer. They do a good job getting I rust off.
So why then did you buy the truck in the first place along with why do you still own it? I had a 2015 6.2 8 speed that was a complete pile of garbage... so I sold it lol.
Thanks Joe! Extra oil changes is a good idea for sure but won't 100% prevent the failure, With that said, I think most owners don't have significant issues with the 14-18 afm systems. The percentage is way too high but most owners will probably trade in the vehicle before it gets to that point. Most failures occur after 100K from what I have seen in the comments but some do have failures as early as 30K. The 2019+ trucks have been having way more issues with the lifters. I think the suppliers may have changed or something
Good on the plaintiffs for taking it to the next level. antidotally the transmissions are a large problem as well, temps get to hot and people tend to service them around the factory 160,000km/100,000mile mark which is a interval that should be updated as well to a reasonable 100,000km/60,000mile mark. private shops dedicated to 6L80 rebuilds and replacements are doing just as good as the 5.4 triton shops around here lol
any idea why the 06 to 14 were not included in this? I'm in the middle of trying to figure out whether to rebuild or replace my 07 5.3 because of this non sense.
This should include ALL AFM engines. I have a 2007 Impala SS with the 5.3 and have had to replace my lifters as one collapsed and I had to pull the head. I like the GM motors if it wasn't for this terrible GOVERNMENT mandated, fuel saving endeavor. Really should be blaming the EPA for forcing manufactures to get better gas mileage. If I wanted better gas mileage, I would have bought a 4 banger!! Sheesh
Same with diesel engines, egr and def systems are just taking life out of the engines and make them consume more fuel. All because of government mandates. If anyone needs to get sued it’s the government.
@@abmtz8537 the government makes rules and standards, manufacturers do what they need to do meet them, often making faulty technology like you mentioned, and then government supports and mandates it, not having a clue of what the outcome will be
Lifters are junk everywhere. If you rebuild or build older engines or are involved in racing / drag racing there are lots of issues going on right now. Issues from cam lobes being destroyed from poor heat treatment or poor heat treatment of the lifer , and even lifters that are not pumping up . I'm talking from the big cam companies. Lifters are just the tip of the iceberg. Guess where many of the lifters are coming from? Where lots of junk comes from today. This is what happens when you kill off manufacturing in your country . We didn't have these issues before. Even in the 80's and 90's it would have been a very rare occasion to have the cam or lifters failing at the rate they are now. I know mechanics having issues with lots of parts today from all the big chain suppliers. Ebay is full of cheap out of spec Chinese crap. Many are driven by cost . Rebuilding older 4 speed , 5 speed transmissions using Chinese parts your going to end up with crap . Their parts are not to spec. I see these all the time. Person buys an older muscle car and having issues with their older manual transmissions. Muncie M21 , M22 and the like. At the heart someone cut corners to save money . It all goes in the garbage and you have to buy good parts . Parts that cost more money. It cost much more money today to rebuild a transmission. We use to rebuild a GM TH350 or 400 for a few hundred bucks . Now it will cost you several thousand dollars . Welcome to today's world . You'd be surprised at how many parts in your doesmestic new vehicles are from you know where.
very true and good summary of the issue. I know there are a lot of QC issues going on right now and sadly I'm not sure if we will ever get back to having quality parts. Maybe Johnson lifters are the way to go but not sure if they are as good as they used to be either.
@Knott Bobby tell me about it, 15 years in the business and never have I seen such terrible "entry-level technicians". Absolutely no tools, no pride I. Thier work, no work ethic, and no capacity to accept constructive criticism.
My 2003 Silverado 2500 HD 6.0 Over 300000 miles It was a X alagasto Service truck with a utility body.. With no problems !! Still at that mileage a great and strong running engine ! Until A texting driver in a Ford Ranger completely totaled me out head on !! Was looking for a similar but a little newer truck But now I'm hearing about these problems.. My 2006 Chevrolet Silverado 1500 same thing over 300000 miles and still runs great !! Why can't they leave well enough alone...? *"AMEN"* !!!
i have a 2019 silverado ltz. and i just had my lifters go. luckily pulled into a dealer. he says 2600 to fix. then calls back two days later. to tell me the cam is damadged as well. and now the bill is 75oo. im sick and am getting no sympathy from dealer or gm. my question is if the lawsuit wins will i get rreimbursed for a later recall or am i screwed
After the parade of engine/transmission/frame rust/electrical problems on my 2010 5.3 Sierra, I'll never buy another GM again. Meanwhile, my 94 Dakota that I bought for $1200 over a decade ago has had like $2000 put into it since then and will outlast most vehicles on the road.
I've got a 2010 5..3. Absolutely hated the cylinders dropping out. After about a year of ownership and after doing some research I ended up buying a Range Technology device that inserts into the OBDII port to keep the engine in 8 cyl mode. While mine does use some oil between changes, it's not as bad as some of the horror stories I've heard and read about, so for that I am thankful. But I agree, they should include all the engines that have the DOD curse.
I've got a 2011 5.3 Tahoe that just past 180,000 and didn't have any lifter problems yet but i did need to get a new transmission at 150,000. I did get the range technology thing around a year ago and i will say that the range thing makes a difference. Before installing it i was losing at least 1 and 1/2 quarts of oil each oil change now its around a quarter of a quart of oil each change and its smooth now. Before i could feel the engine going frpm 4 cylinders to all 8 and it tows better too.
In the last two months I paid for a NEW GM 5.3 for my 2017 Sierra because of lifter failure! Had #5 misfire codes at 98k miles and the cam and lifters were seriously scored. Yes, I took pictures of everything!
My 2015 Chevy Suburban 5.3L lost the lifters in the number 7 cylinder. I installed a programmer at 85,000 miles, but at 124,000 miles the AFM lifters failed. I am having all the lifters replaced for $4,000.00. The mechanic advised since I have the AFM disabled I should not have a lifter failure again. I hope this information helps.
Love my 2016 5.3 Silverado…however, I had the torque converter in my 6L80 go bad and ruin the transmission. Then not even 2,000 miles later, the lifter in the number one cylinder collapsed due to top lobe of the cam chipping off…spent several months trying to get it into a shop to delete the afm system then have it tuned to fix the ecm. After several months of waiting, it’s finally fixed and runs 1000% better than when it had the afm system. Im still getting 16-18 mpg city and 21-22 highway with a stock style cam and vvt turned off. As an engineer, it’s a complete nightmare design especially in the 2019+ models that have the bad lifters in every cylinder and angled pushrods that get bent easily.
Not necessarily…see I did my research before fully committing with the delete kit. Like I said I was already having small issues with Afm affecting the engine and transmission (throttle was super lagging in traffic, put unnecessary load on engine and transmission during v4-v8 downshifting/up shifting). So I knew I wanted to keep it in V8 mode because going down the highway or in traffic it ran wayyy smoother with all 8 cylinders doing what it was suppose to (running all the time). So I tried the range disabler just to keep it in V8 mode and it worked great. Trans shifted much better, no unnecessary load on engine and trans during downshifting, and overall just better driving experience in V8 mode. Then like I said trans and afm lifter finally gave up (not due to range, but faulty torque converter and bad lifter/cam). After everything I went through and experienced I knew it was time to do the full delete on the AFM system. I went with a Brian Tooley Racing delete kit that replaces the cam various options on this), all lifters (with a hydraulic LS7 Style lifters instead of the afm style lifters) and I did new pushrods just as an extra precaution. Then you have to go into the ecm and turn off AFM from engaging. I live in Charlotte NC but I’m going against traffic in the mornings to go out of the city. So it does great cruising to work on the highway about 19-21 mpg and my “city driving” is going back home on country roads until I get into the city. Which like I said averages about 16-18 in city. Not trying to sell people on the swap because I know people who haven’t had issues with their trans/afm. I just rest easier at night knowing I don’t have to deal with another collapsed lifter.
@@anthonymeza8794 yes it did. It was kinda funny because i drove it like 45 minutes straight (no issues or noises whatsoever). Then on the way back it sounded like it was having an issue staying in overdrive. Like rev bouncing on highway/growling a little in 5-6 gear. I was dumb and babied it home, but since the torque converter was the issue, the trans wouldn’t have survived anyway. It happened around 115,000 miles which typically when you’ll see trouble with the 6L80 torque converters. So got a new trans with 100,000 mile warranty. I also did a trans flush about 3,000 miles before the torque converter acted up, so don’t know if that helped lead up to the torque converter failing. I’ve always been iffy about trans flushes anyway.
@John Brennan congratulations on this full on conversation with yourself with all your complaints. This hillbilly engineer has been working on cars his whole life, but you know, thanks for the new handle name. I kinda like it ☺️ @hillbillyengineer
I used to work for the biggest distributor of GM parts in Texas. And I have delivered countless lifters to shops throughout the Houston area. Thousands and thousands of lifters. It's ridiculous that's how bad it is a lot of the times the lifters are in back order because everyone is ordering them
Not sure if I've been able to avoid any future issues with the lifters, but what I did on my 09 Sierra with the 5.3L was use my friends HP Tuners module to shut off the AFM. It now only uses 8 cylinders and doesn't switch back and forth from 4 to 8 cylinders. Hope it helps.
I have had my afm in my 2014 silverado with 105000 miles disabled with one of those range devices that plugs in to the port under the steering wheel for 60k now and I havnt missed 4 cylinder mode ever since. Although I'm sure because of the design of the motor I'm still at risk of lifter failure
@@downsouthallah4800 I did back at 45k and I was still under warranty so the dealer fixed that for me I bought the truck in the winter with 41k on it summer came around and I was pissed I didn't have ac
The afm honestly does little to help fuel economy, maybe 1-2 mpg gain at most. It is the dumbest thing gm has ever done. The 2.7 l turbo 4 might top it in a few years though if gm continues to put it in the Silverado, it’s a doomed engine from the start.
I've been an automotive technician for 18 years and I've seen several of the gm trucks and SUV's come in with this problem Have also seen these vehicles go to the dealership to try to get repaired and they come right back with the same problem or worse the best way to fix it is to delete it and yes they should have a lawsuit for all of them
I am hoping for this to get somewhere. I love my 15' Silverado, but Im sure my lifters are a ticking time bomb. I have a Range AFM delete module and it seems to have helped a slight rattle I noticed a while back(could only hear it in V4 mode at very low RPM). But the writing is on the wall and I know it'll be an issue eventually. At 108K miles and so far nothing substantial repair wise, fingers are crossed. Love the content. Keep us updated!!!
@Gold Standard, I have a 2015 GMC Sierra 1500. My lifter went out in August 2021 out of the blue. Truck was at 145k miles. The dealer wanted $15k for a new engine after taxes. We were able to talk them down to $6500 with labor and tax because there was no way we were going to pay that markup. So they put a new engine, and I got the warranty 100,000 or 3 years. Long story short, I’m looking into getting the range afm delete. You’re right about the engine being a ticking time bomb. I hear a click every time I move from a dead stop sounds like it’s from the chasis and then my suspension is fine but when I go over those rough concrete speed bumps I hear an audible (can crushing) kind of sound from the front and rear suspension. And I go over those slowly lol. But yeah, keep us updated. And merry Christmas to you and your family.
my 16 silverado ticked in v4 mode for a while and eventually the lifters on the passenger side went solid and messed up my camshaft and damn near blew my whole engine. in hopes that they don’t go bad, but if they do get the DOD delete kit from texas speed and just bypass the afm issue all together that’s what i did and the truck runs better than before!
Interestingly enough the Service Manager at my dealership told me to get the Range AFM disabler. He didn’t trust the AFM. He put the Range on his Silverado.
I bought my 2021 GMC Sierra 1500 with the 5.3 liter engine January 21, 2021. In May we drove 2,000 miles to Maine. The next day the #6 cylinder pushrod failed and the engine shook like it wanted to exit the engine compartment. Took it to the local GM dealer. They had five in the shop just like mine. My truck had less than 4,000 miles on it. Only the left engine bank was fixed - the only broken part. GM wouldn’t fix the right side because it wasn’t broken. Yet. So that’s a crap shoot. The replacement time was quoted as “we don’t know” and “over four weeks” due to availability of parts, specifically gaskets. I was stunned at the amount of parts that had to be replaced. I’d really like GM to replace the lifters on the right side of the engine at their cost so I feel more comfortable that it won’t fail.
I have a 2015 silver and have not had any major issues requiring service YET, but my lifters have always been noisy. Now I do feel like they are a ticking time bomb.
Can Hear Every Valve Rattle On Long Extended Trips... Another fine product brought to you by the Great Mistake Corporation. Non dealership engine technicians make twice as much money in actual engine shops. Then they do in the dealership. Good luck.
Depending on your transmission you can disable afm without any aftermarket devices. If you have a 6 speed put it in manual and select 5th gear, 8 speeds select 7th gear. This disables afm on 14-18 I know. I use it on my 17 Tahoe and 18 Silverado.
Gm has covered/hidden this issue for many, many years. Hope everyone nails GM. They are just being cowards, they need to build better products and stand behind them. Period....
What about 07-13? I have an 07 Tahoe with the 5.3L that has AFM & have spent 6K so far getting all 16 lifters replaced on 4 different occasions. Better believe I saved all my receipts!
When i researched about my oil pump issues, a guys did mention that this was gonna happen next and advised me to sell or trade if possible and man am i glad i did!
I have a 2014 Sierra with the 5.3 with 105,000 miles on it and it has been flawless. I am starting to get a small lifter tick on it now and that worries me, I would love to get the refreshed 2022 Sierra with that new interior but I don’t know if I could trust the new ones with all these AFM issues they are having.
Same mileage as mine I switched to royal Purple oil and try to change my oil more regularly around 30% or so I change it at. The royal purple is sold in a 8 pack on Amazon too unfortunately since my last oil change the price has jumped up a bit. Anyways I had that small lifter tick mainly heard it in drivethrus next to a wall idling. Since the royal purple tho the tick has been gone. Fingers crossed
I don't trust the new ones yet. I might consider a 23 or 24 but the 22s have too many problems. Honestly tho, If the truck has been good to you, I would do an AFM delete and a torque converter swap and keep it for another 100K.
I had Nissan Titan 2006 Zero issue until i sold it with 227k miles, i bought 2017 Silverado 102k miles now and the lifters start tapping when the oil gets hot, transmission shudder. I will not buy any GM products, will find out Toyota tundra or go back to Nissan Titan aging.
Reading about all of these failures, makes me feel even more better. That I kept my 2003 Silverado, and not trade it in for a new truck. My truck at 265,000 miles and still going strong.
My buddy's 2021 blew up at 6K miles. If you trade it in, you're better off with Ford, Dodge, or the 2.7T 4 banger if you go GM (which actually isnt a bad engine so far).
I had a 2009 Silverado 1500 with a 5.3 engine. Bought it brand new. That thing would consume a quart of oil about every 1500 miles. This is quite concerning since it only held six quarts of oil. Back then I remember reading about it having something to do with the AFM system. One would think that they would have fixed the issue by now, but Im glad someone is trying to do something about it. They need to go further back than just 2014 as this has been a problem for several years prior. I know GM up'd the oil capacity to 8 quarts on newer models. But with the amount of oil my truck burned you could theoretically never have to change the oil. Just check, add, and replace the oil filter periodically.
I'm gonna need to follow up with this. I have a 2011 1500 Silverado & just had to have the engine rebuilt due to several lifters not working & causing damage to the cam shaft as well. I love my Chevy but having to rebuild with ONLY 102,000 miles was a huge gut punch to my Chevy faith. I now have an EVAP leak that won't go away. I live in my truck with work so this is a huge crush.
I had a 2012 Chevy 1500 that I had to rebuild the engine at 95000 miles! It cost me $4800 to do! I have always been a Chevy fan but after this I was so mad I went out and bought a 2019 laramie longhorn!
I had this happen on my 2015 5.3L at 30k miles. Luckily I caught it right away without any further damage to the engine. It took almost 2 months for the dealer in my area to get the lifters replaced because they were so backed up on repairs. While I still have the truck, I will not be purchasing another GM product with this “technology”.
2015 GMC 1500 same lifter failed twice ( #7) With in 6 months... Ended up doing a full DOD delete kit which cost almost around 4 grand in parts and labor.. I'm very interested in this law suit... My mechanic said this AFM crap has been an issue since it was first seen in the 2008.. Cant believe they have never fixed it..
I had 2019 Ram 1500 that I bought new and decided in August to trade in for 2018 Silverado. The Silverado with 5.3 only had 20,000 miles on it. Within few weeks I hate driving the Silverado, just always jerking and shifts are awful. Times slowing down for light it down shifts hard. But put in low gear and shift it to 5th so it will shift normal up and down thru 1 and 5th gears and drive around and it's a totally different truck. Shifts great and has that v8 pep. But if leaving it in normal Drive gear it's so sluggish and shifts are always so strange. Days i regret leaving Ram for Chevy. I never had problems with my Rams. I know all manufacturers have there problems, wife works for Ford and wouldn't let me get Ford. She sees all problems they have with the F150 . Been wanting to get Range Technology to keep the Silverado in v8.
They all have issues sadly. Pretty telling that your wife doesn't want you getting a truck from the company she works for tho lol. They all need better quality control and better suppliers.
You must have the 8 speed trans and thats also is very common, you need a trans flush with that special hp fluid which by the way is expensive per quart
@@kennymartinez973 nope I have the 6 speed. Everything I've read and watched commen on the 6 speed. My brothers is same way and guy beside us at our seasonal camping sight is same. They both say it's always jerky and strange shifts
Its a shame older models aren't included. Many of us have well maintained older trucks (2010+) without a million miles on them that have the same stupid AFM design.
Took out my 2008 5.3 at 80,000 miles. Then at 94,000 miles. On top of using a quart of oil every 1,000 miles since new. Shameful the 2008 to 2013 owners got nothing because it was still being denied and covered up back then.
@@TheSundaeDrive Both cat converters needed replaced at 54,000k $1,400 but warrantied and the oil sender went bad at 55,000k $950. Two DOD repairs @ $3,500. Tail lights all stopped @ 82,000k. $550 to rewire, circuit boards and bulbs. I gave up at DOD failure and owed too much to sell. So had to pay for 2 years while it rotted in yard and I drove my GF car. Bought anew 2018 Ram and ended my 30 years of Chevy trucks. Looks like 2021 and they are still making the same junk.
I've driven GM all my life but after all the garbage I've experienced with my 2017 Sierra I will NEVER buy another GM product. My wife's Terrain is also a piece of trash. Their warantee covers nothing, they make excuses for any issue you have saying it's not covered. My advice to everyone out there, buy anything but GM!
Does anyone know some of the symptoms? I bought a GM certified 18 Silverado (5.3) with 22k miles. I've had nothing but issues since bringing it home. The primary issue has been a sputtering that usually happens around 1500rps. It seems like the motor is cutting out. I was recommended Top Tier Fuel, which I've since switched to. I'm paying out the ass for TT Super Premium and it's still sputtering. It threw codes a few weeks back for misfire. Since then it seems to lack power. My gramps rusted out '02 runs better.
Just 3 days ago my 2021 Silverado High Country 1500 was put on a Flat-bed truck & sent to my local Chevy Dealer for this very same repairs! I NEED MORE ADVICE please reply?
Hopefully it forces gm to at the very least issue a recall so those who have paid out of pocket can be reimbursed and people like myself who so far, knock on wood , havnt had any issues yet can get the faulty parts replaced without having to wait for something to go wrong and then have to pay.
I was hoping that when ac condenser went out, paint started peeling, and oil pump went out as well it was just a matter of time before lifters gave out man!
I have been a GM guy since I was 17, I'm 43 and I got sick of the Lifter and Transmission issues. I decided to try a Ram and so far what a night and day difference. I wish GM would get their act together. GM use to represent reliability and strength, now its more on how fancy they can be.
The cateye really does look the best of any gm pickup, and the avalanche isn’t included in that. It’s not bad but it doesn’t look as good as a Silverado cateye. Every other gm truck looks garbage to me, a clean fisheye doesn’t look bad but the cateyes look best
I own a 2007 Avalanche that had the AFM. At about 118,000 miles, I started getting error codes like traction management faults and other driveline issues. A scan showed it was all because of an issue with my #7 cylinder. Cylinders 1, 4, 6, and 7 are the AFM cylinders. I stopped driving the vehicle and started ordering parts. I ordered a new cam for a 4.8 engine, a set of 16 non-AFM lifters, a new timing chain, a non-solenoid valley cover, a gasket set, and a set of top end bolts (heads and intake manifold). My son and I did the work in our South Carolina driveway which means in October because of the summer heat and humidity. I got my parts through a GM Parts outlet, but places like Summit have AFM delete kits as well. I also had to get my ECM reflashed so it wouldn't be sending AFM error codes. It now runs like a champ at 151,000 miles. I guess mine is too old for the lawsuit.
@@TheSundaeDrive yes after looking it up for the 6.6 gas I believe you are correct and a couple of the smaller displacement engines in certain trim levels do not either so not sure how emissions rules vs engine longevity reconcile.
I also bought a 17 new with the 6.2L. A lifter failed today at 59,105 miles. Thankfully I paid for the 7 yr, 100,000 warranty. Two local dealerships wouldn't even get me in for 3 weeks, and so I had to trek to the dealership I bought it from to get it in for diagnosis. Crazy! FJB
So you are saying I should buy my Range AFM Disabler now on my 2008 Silverado with 160,000 miles? I am suspecting oil consumption issues and have replaced the oil pressure switch and filter screen 2x in the past 2 years.
If you can't afford a full afm/dod yes. I would probably recommend doing the range. It won't fully prevent the failure but will probably help make it last a bit longer. Not a guaranteed fix tho
I have been a chevy man for years.Built motors ,raced cars .I do own a 2018 Silverado. Love the truck absolutely can't stand the cylinders dropping off.It defeats the hole reason of owning a truck ,Everybody likes has mileage, but IT'S A TRUCK NOT A VEGA. If MY TRUCK STARTS DRINKING OIL AND LIFTERS START STICKING .SHITE GOING TO HIT THE FAN.With the right SERVICE motors should last a long time .I do have life time drive train warranty,free oil change which they SERVICE regularly.That being said oil should never get dirty to cause any lifter problem or rings ,valve guides ware. SO ITS ON THEM .SO THEY WILL REPAIR IT ,WARRANT THE REPAIR IT OR EAT IT.MERRY CHRISTMAS AND HAVE A SAFE AND HAPPY NEW YEAR! LGB!
I just started finding out about all this and just bought a 2018 Chevy Silverado 1500 with the 5.3 about 1 1/2 months ago, I am buying a AFM disabler today for it so it doesn’t keep switching back and forth and causing premature wear, hopefully they get this fixed soon and do a recall and fix this issue
Possibly but lots of people commenting with short change intervals and still having the failure. I personally changed my oil 8-12K Miles and probably had to add a quart in between. I didn't have a failure up through 108K miles and then I deleted afm. Full guide up on the channel
My friend's 2015 just went out at 105000 last month and all the service work done at dealer. He was upset because warranty run out a few thousands mile earlier. Another active fuel management fails again.
GM needs to do away with AFM and DFM for good in all GM vehicles.
agreed!
Agree
I agree with you but they won't do it due to the Cafe standards the government set up for mpg of vehicles. Thats really the issue they try and get the trucks more fuel efficient and it causes more problems than it fixes. It is a truck and people who buy trucks for the most part I think understand that you will not get 40 mpg out of it lol
That AFM in vehicles with 8-speed autos has been causing transmission shuddering in some vehicles when going into V-8 to V-4 mode. GM. changed the transmission oil specs which helped out quite a bit.
No they will double down on it..... they will never do the good thing.
I'm a former Chevy tech and I cannot tell you how many of these lifters I've replaced. I've replaced lifters, pushrods and lifters, and lifters, pushrods, and camshafts. The lifters either get stuck expanded or stuck closed and either bends the pushrod or just causes a misfire. Job pays 9 hours to do one bank or 11 for both banks but we were doing so many of them, we were able to knock out 1 bank in about 2 hours. I've seen 2020-21 trucks/SUVs with only 1800 miles in them. Really sad.
So all aftermarket lifters are Chinese junk?
@@Mr-ow3mk doubt it. The lifters that GM are using to replace the factory lifters are junk. Just replacing junk with junk. The lifter guides are plastic, should tell you everything you need to know
@@Mr-ow3mk I mean the real repair is to undo afm with solid lifters and cam, but I'm certain GM not participating in that.

I got mine from SEARS HARDWARE from 15 years ago. I quit my job and retired. The payment was around $4.00-$5.00
I had a 2015 Sierra with the 5.3l. I ran it up to 150k miles in just 3 years and had tons of issues with the engine. Multiple trips to the dealer, then after the warranty, multiple trips to the local engine shop. No one figured out what was wrong with the truck. Then one day I was road tripping it, I had the oil changed the day before and I know the engine oil was full and the low engine light came on, and that was it. Only 1000 miles on a fresh oil change and the thing was low on oil. I had always that issues since my first oil change at 5,000 miles a the dealer. It never leaked. That 5.3 made a rod pop out the side of the block. That was that, I sent it off to the junkyard.
I have since purchased a 2006 Silverado 5.3 it had 15,000 miles on it in 2018. Now it has 165k miles on it, and I have had zero engine issues with that truck.
I wouldn't buy any GM engine that has active fuel management. I'm sitting here wondering if I can recoup any of the money I put into my 2015. If not, I hope you guys win this lawsuit.
That stinks Nate. Sorry to hear about all those issues. That's incredibly frustrating. The only way to really deal with it is to delete afm fully. 2006 and older is simpler which usually = better
@@TheSundaeDrive That's why I went and found the cleanest and low mileage 2006 GM truck I could. Been very happy with it.
I've often wondered if I deleted AFM day one on my 2015 just maybe I wouldn't have had issues.
The very reason, if it's going to be a new vehicle. Honda or Toyota ONLY, the new American vehicles are unreliable and European vehicles are over engeered plastic garbage.
Wife's car is a 2010 Toyota camry, the daughters car is the old family beater/spare 1996 Toyota corolla.

I literally had a lifter collapse today in my 2017 GMC sierra with 62k miles. I will be calling the dealer tomorrow to see what they can do. The failure at 62k miles and a clean service record is ridiculous!
U might be lucky with your 5 year drive train warranty
Being a dealer tech, I've seen them go on 2021 5.3 and 6.2 as early as 1000 miles. And after we replace them, a few come back 3000 miles later for the same thing, replacing junk with junk
So frustrating. They need to get better parts suppliers
If you are out of the powertrain warranty (i think gm shrunk it to 60K) they will still normally cover a large portion of the repair if not all of it since you are so close and the truck is so new
My 21 just went out with 14k miles
There needs to be a transmission class action lawsuit as well.
Agreed! The transmissions have been awful
@@TheSundaeDrive 42k on my 2015 and it just gave out sending metal all through it no warning. trans was crappy from day 1 brought it back several times and was always told operating as designed. 3600 bucks later its rebuilt still has some weird shifts from time to time. I will say HP tuners has helped quite a bit especially with the TCC lockup speeds and slip.
The transmission is easy to fix. Flip flop the thermostat or get there new bypass valve. But yeah it’s been a horrible system from the get go.
@@Ray00069 that was done at around 7k miles and still failed.
@@Scott19 Yeah probably because they kept the same weak torque converter that destroyed it twice lol

@@trollmode3863 fixed lifters on my 2007 twice - I will never buy a chevy again unless there is a serious redesign
This is a great example of how Manufacturers’ engineers actual knowledge and quality control have gone out the window in favour of bells and whistles that are unnecessary and troublesome in themselves.
Agreed!
Good 'ol government mandates!
This is a great example of a lawsuit that makes no effort to differentiate actual defects from GM and cases of lifter failure due to owners with room temp IQ's that don't change their oil often enough, don't check their oil level, add so much oil it causes oil aeration, drives short trips all winter long and causes the oil level to increase due to the amount of unburned fuel that's diluting the oil down and causing wear, etc. If your lifters made it 100k miles and then later fails, that wasn't because of a defective lifter, that's a case of an owners that joined the "I change my oil ever 7500+ miles cuz I buy the good stuff" when their DI engine has been loading up that oil with diesel-like soot and unburned fuel for that entire interval and has caused wear and sludge formations that cause lifters to malfunction.
I used the Range AFM disabling module on my 2010 5.3 Silverado and it literally saved the engine. The #1 & #7 cylinder plugs would foul and this started under warranty. GM would perform service to mask the problem and get you through warranty. The truck started using oil too. I discovered the Range AFM module and drove the truck to 230K before trading it in. Plug fouling stopped, oil consumption stopped as the engine cleaned itself up. I transferred the module to the 2018 Silverado I purchased also with the 5.3 so I’m hoping for the same long term results. I wouldn’t drive the GM product without disabling the AFM it’s junk!
Don't leave that thing plugged in if your not driving every day. Replaced 2 batteries because of that device. It's great but puts a slow constant draw. I think I'm just going to get a tuner because they can disable afm and don't have to be plugged in. Also don't unplug that thing after the engine is running. My truck stayed in 4 cylinder mode during idle and was running like crap, couldn't even drive it because it wouldn't go to v8. Luckily I disconnected the battery and the computer reset, all has been good since.
Good feedback Will! Glad to hear it worked well for you
Good tips Jordan. Thanks!
Thanks for your post. I just bought a Range after my 2015 lifters collapse and bent push rods. I’ve been trying to research how it works over time.
I used the Range AFM disabler on our 2018 Cadillac Escalade 6.2. Worked awesome.... the lifters sometimes would tick louder sometimes before the Range Afm disabler. After quiet all the time. I also used Royal Purple oil as well!
thanks for your reply. I bought the Vet new in 2017 installed the Range a month later so far so good it now always stays in 8 cylinder. Enjoy your ride, nothing makes me smile more than a full tank of gas & 8 cylinders running! keep smilin

@justin, we do too. No major issues with our blazer
I want to ask the gm executives a simple question. Why do you insist on chasing this rabbit down its hole. You've known since 07 that this design is extremely flawed so why not just do away with it already.
People dont buy trucks for good gas mileage. The same goes for sports cars so just eliminate the AFM from your V8'S and sell your products on reliability rather then fuel economy.
I've been a die hard chevy man for a long time. I'm currently looking to buy a new truck but I'll be dammed if I spend 70k on a truck that's going to have major engine problems before hitting a hundred thousand miles... it makes no sense as a consumer and has me leaning towards dodge as an alternative to my beloved chevy.
I don't think I'm alone in this. Gm needs to rethink there position on vehicles.
Unfortunately it is the epa and regulations driving the inclusion of tech like this.
@@TheSundaeDrive yes sir. I'm a diesel mechanic and none of the epa regulated technology works the way they claim it should. Nothing but problems with it but at least in this case were not talking about catastrophic engine failure. The dealership limited the carbon emissions to the exaust and external parts. GM just keeps repeating the same failure over and over at the cost to the consumer. At least try something different. What they're doing is infuriating.

My 11' WT 4x4 with the 4.8 has 253k and it's been amazing. Replaced 1 motor mount, shocks & struts, front hub bearings, brakes, tires and 1 blower motor. I put a corvette servo in the trans at 230k to help hopefully get it to 300k. It runs and drives fantastic...friends and neighbors who borrow it can't believe it has the miles it does and that WT interior with the rubber floor really holds up over time. It's not a powerhouse by any means, but it scoots pretty good unladen and has pulled anything I've hitched to it without too much drama. I'm perfectly happy with this thing and would keep it forever, but I'm in the upper midwest and rust is starting to bubble up on the bed. I know in 2 years it's going to look like garbage and while I don't mind some well-earned patina, I can't stand rust. I know I'll need to replace it soon, but I'm really not looking forward to the inevitable tech that newer trucks are laden with. Based on experience with my current truck, GM has earned my business on the next one but I'm not gonna lie...I'm terrified. I spec'd a 21' WT online this morning and it doesn't appear that the manual transfer case is still available? I can't spec the locking axle without adding the Z71 package? I knew my beloved hand-crank windows were long gone but I figured I'd still be able to mostly have it my way. I'm going to ease on over to the Ford site this afternoon to see what their idea of "stripped down" is these days.
Glad to hear it has been holding up well for you! Hopefully it gets you to 300K. I don't think there are any manual transfer cases anymore sadly. Stay away from 19-22. Hopefully by 23 they fix the lifters.
I wanted low range in the transfer case. Backing a loaded trailer in soft conditions means smoking a transmission or clutch without it. You have to buy the offroad package of some kind to get it. HDs come standard with it. Buying anything other than fully optioned is a nightmare experience. Right now, from each manufacturer's website, Ram offers the most truck for dollar. Ford is the most money.

Going through this right now avalanche 07 in the shop
I replaced the lifters and cam on my 08 gmc because #7 lifter got stuck. I ended up dod deleting it and had a street tune. The truck ran great after that. I gave it to my son, he drove it for 2 years and sold it. He bought a 2014 chevy z71, i told him to go have the afm or what ever it's called deleted because it's just a matter of time. It only has 50,000 miles on the 2014 and he has an extended warranty until 100,000 miles, hid deductible is only $100
I always wondered how they weren’t sued before when it came to these AFM. EVERYONE tells you to delete these things before you do your ls swap. It wasn’t a matter of if they would go bad but when
exactly. It is a bad design
Can you delete this with a chip that plugs into the OBD2 port?
You can disable it but doesn't fully prevent the failure although a lot of guys have great luck with it.
Why wasn't the v-6 included in the lawsuit?
Thanks for the info. While I was out leading a Jeep ride yesterday my wife bought me a truck as a surprise. It’s a 2016 and I had no idea what any potential problems would or could be. I watched your other video and BAM! It was all right there. Thanks for keeping people informed.
That's what happens when you take a phenomenal engine (LS family) and add emissions BS.
Lifter issues have been a thing since gen 3, then you have broken valve springs, piston slap on early LS, oil consumption etc.
Weell said @shem
Thanks for the information. I have a 2014 Silverado with only 50K miles (hunting and boat towing mainly). Besides frame rust, AFM failure is always on my mind. My game plan is to change the oil with no less than 25% life in order to keep crude out of the AFM system. Maybe if they win this suit, there will be a recall. The next concern will be that the recall fix will be worse than what I have now. Thanks again, you have a new subscriber. Joe
I owe a silverado 6.2 and at aprox. 10,000 I did dod delete thru the pcm. I changed the oil at every 5000 miles or 30% of oil life and still at 95000 my lifters collapsed.
Yeah, what's up with the frame rust????? I bought a 2015 in 2017 with 30000 miles on it and I had all sorts of rust already on the frame.

It cracks and water and salt get behind it. I used rattle can Rust-Oleum rust reformer and Rust-Oleum paint and fluid film all over and in the frame rails. It looks good. It is a constant battle. I only have 50K miles so rust will eventually win. Joe p.s. if you go at it get a needle scaler from harbor freight and a welding slag hammer. They do a good job getting I rust off.
So why then did you buy the truck in the first place along with why do you still own it? I had a 2015 6.2 8 speed that was a complete pile of garbage... so I sold it lol.
Thanks Joe! Extra oil changes is a good idea for sure but won't 100% prevent the failure, With that said, I think most owners don't have significant issues with the 14-18 afm systems. The percentage is way too high but most owners will probably trade in the vehicle before it gets to that point. Most failures occur after 100K from what I have seen in the comments but some do have failures as early as 30K. The 2019+ trucks have been having way more issues with the lifters. I think the suppliers may have changed or something
Good on the plaintiffs for taking it to the next level. antidotally the transmissions are a large problem as well, temps get to hot and people tend to service them around the factory 160,000km/100,000mile mark which is a interval that should be updated as well to a reasonable 100,000km/60,000mile mark.
private shops dedicated to 6L80 rebuilds and replacements are doing just as good as the 5.4 triton shops around here lol
agreed - nice to see someone stepping up to hold GM accountable. It is crazy how many 6l80s fail
Triton spark plug launch was my last straw with my low mileage POS F-150 and put me into the Tundras.
I'd take a 6l80 before another 4l60 though 🤣
It's actually not the trans that fails initially, it's the torque converters then it gets run through the trans and wipes it out
@@dumasmcgee true. My cousin 6l90 converter did the same
Why does that list say "2014-2016 Chevrolet Avalanche"?
No idea unless they kept making it overseas.
any idea why the 06 to 14 were not included in this? I'm in the middle of trying to figure out whether to rebuild or replace my 07 5.3 because of this non sense.
This should include ALL AFM engines. I have a 2007 Impala SS with the 5.3 and have had to replace my lifters as one collapsed and I had to pull the head. I like the GM motors if it wasn't for this terrible GOVERNMENT mandated, fuel saving endeavor. Really should be blaming the EPA for forcing manufactures to get better gas mileage. If I wanted better gas mileage, I would have bought a 4 banger!! Sheesh
Hit the nail on the head
Same with diesel engines, egr and def systems are just taking life out of the engines and make them consume more fuel. All because of government mandates. If anyone needs to get sued it’s the government.
@@abmtz8537 the government makes rules and standards, manufacturers do what they need to do meet them, often making faulty technology like you mentioned, and then government supports and mandates it, not having a clue of what the outcome will be
Lifters are junk everywhere. If you rebuild or build older engines or are involved in racing / drag racing there are lots of issues going on right now. Issues from cam lobes being destroyed from poor heat treatment or poor heat treatment of the lifer , and even lifters that are not pumping up . I'm talking from the big cam companies. Lifters are just the tip of the iceberg. Guess where many of the lifters are coming from? Where lots of junk comes from today. This is what happens when you kill off manufacturing in your country . We didn't have these issues before. Even in the 80's and 90's it would have been a very rare occasion to have the cam or lifters failing at the rate they are now.
I know mechanics having issues with lots of parts today from all the big chain suppliers. Ebay is full of cheap out of spec Chinese crap. Many are driven by cost . Rebuilding older 4 speed , 5 speed transmissions using Chinese parts your going to end up with crap . Their parts are not to spec. I see these all the time. Person buys an older muscle car and having issues with their older manual transmissions. Muncie M21 , M22 and the like. At the heart someone cut corners to save money . It all goes in the garbage and you have to buy good parts . Parts that cost more money.
It cost much more money today to rebuild a transmission. We use to rebuild a GM TH350 or 400 for a few hundred bucks . Now it will cost you several thousand dollars . Welcome to today's world . You'd be surprised at how many parts in your doesmestic new vehicles are from you know where.
very true and good summary of the issue. I know there are a lot of QC issues going on right now and sadly I'm not sure if we will ever get back to having quality parts. Maybe Johnson lifters are the way to go but not sure if they are as good as they used to be either.
Some much Chinese junk in the market place!!!
CHEAP CHEAP CHEAP!!!!
100 percent correct, I recently built a LQ4 with comp cam lifters and it took about 100 miles for them to pump up completely.
@Knott Bobby tell me about it, 15 years in the business and never have I seen such terrible "entry-level technicians". Absolutely no tools, no pride I. Thier work, no work ethic, and no capacity to accept constructive criticism.
My 2003 Silverado 2500 HD 6.0 Over 300000 miles It was a X alagasto Service truck with a utility body..
With no problems !!
Still at that mileage a great and strong running engine !
Until A texting driver in a Ford Ranger completely totaled me out head on !!
Was looking for a similar but a little newer truck But now I'm hearing about these problems..
My 2006 Chevrolet Silverado 1500 same thing over 300000 miles and still runs great !!
Why can't they leave well enough alone...?
*"AMEN"* !!!
i have a 2019 silverado ltz. and i just had my lifters go. luckily pulled into a dealer. he says 2600 to fix. then calls back two days later. to tell me the cam is damadged as well. and now the bill is 75oo. im sick and am getting no sympathy from dealer or gm. my question is if the lawsuit wins will i get rreimbursed for a later recall or am i screwed
After the parade of engine/transmission/frame rust/electrical problems on my 2010 5.3 Sierra, I'll never buy another GM again. Meanwhile, my 94 Dakota that I bought for $1200 over a decade ago has had like $2000 put into it since then and will outlast most vehicles on the road.
Have a buddy with a couple Dakotas and loves them
I like to find one that was around 2000 square body … Good trucks 240k plus
Same issues with my 2008 5.3 silverado
I've got a 2010 5..3. Absolutely hated the cylinders dropping out. After about a year of ownership and after doing some research I ended up buying a Range Technology device that inserts into the OBDII port to keep the engine in 8 cyl mode. While mine does use some oil between changes, it's not as bad as some of the horror stories I've heard and read about, so for that I am thankful. But I agree, they should include all the engines that have the DOD curse.
Just curious, how many miles are on your truck?
Just because you eliminate it software wise, doesn’t stop the problem. The crap components are still chugging along in your block.
@@TheSundaeDrive Just about to roll over to 149K
Awesome!
I've got a 2011 5.3 Tahoe that just past 180,000 and didn't have any lifter problems yet but i did need to get a new transmission at 150,000. I did get the range technology thing around a year ago and i will say that the range thing makes a difference. Before installing it i was losing at least 1 and 1/2 quarts of oil each oil change now its around a quarter of a quart of oil each change and its smooth now. Before i could feel the engine going frpm 4 cylinders to all 8 and it tows better too.
Appreciate the info but as with many class action automotive suits it be dragged out for years and the consumer will ultimately lose.
In the last two months I paid for a NEW GM 5.3 for my 2017 Sierra because of lifter failure! Had #5 misfire codes at 98k miles and the cam and lifters were seriously scored. Yes, I took pictures of everything!
My 2015 Chevy Suburban 5.3L lost the lifters in the number 7 cylinder. I installed a programmer at 85,000 miles, but at 124,000 miles the AFM lifters failed. I am having all the lifters replaced for $4,000.00. The mechanic advised since I have the AFM disabled I should not have a lifter failure again. I hope this information helps.
Please drive your truck in M5 drive mode from here on out!!! It disables AFM and keeps it in V8
It helps. Doesn't prevent failure but can help.
I have a 2013 and the lifters locked up and took out the cam lobes why isn't that model included.
Love my 2016 5.3 Silverado…however, I had the torque converter in my 6L80 go bad and ruin the transmission. Then not even 2,000 miles later, the lifter in the number one cylinder collapsed due to top lobe of the cam chipping off…spent several months trying to get it into a shop to delete the afm system then have it tuned to fix the ecm. After several months of waiting, it’s finally fixed and runs 1000% better than when it had the afm system. Im still getting 16-18 mpg city and 21-22 highway with a stock style cam and vvt turned off. As an engineer, it’s a complete nightmare design especially in the 2019+ models that have the bad lifters in every cylinder and angled pushrods that get bent easily.
Did the torque converter make a growling noise when going out?
Not necessarily…see I did my research before fully committing with the delete kit. Like I said I was already having small issues with Afm affecting the engine and transmission (throttle was super lagging in traffic, put unnecessary load on engine and transmission during v4-v8 downshifting/up shifting). So I knew I wanted to keep it in V8 mode because going down the highway or in traffic it ran wayyy smoother with all 8 cylinders doing what it was suppose to (running all the time). So I tried the range disabler just to keep it in V8 mode and it worked great. Trans shifted much better, no unnecessary load on engine and trans during downshifting, and overall just better driving experience in V8 mode. Then like I said trans and afm lifter finally gave up (not due to range, but faulty torque converter and bad lifter/cam). After everything I went through and experienced I knew it was time to do the full delete on the AFM system. I went with a Brian Tooley Racing delete kit that replaces the cam various options on this), all lifters (with a hydraulic LS7 Style lifters instead of the afm style lifters) and I did new pushrods just as an extra precaution. Then you have to go into the ecm and turn off AFM from engaging. I live in Charlotte NC but I’m going against traffic in the mornings to go out of the city. So it does great cruising to work on the highway about 19-21 mpg and my “city driving” is going back home on country roads until I get into the city. Which like I said averages about 16-18 in city. Not trying to sell people on the swap because I know people who haven’t had issues with their trans/afm. I just rest easier at night knowing I don’t have to deal with another collapsed lifter.
@@anthonymeza8794 yes it did. It was kinda funny because i drove it like 45 minutes straight (no issues or noises whatsoever). Then on the way back it sounded like it was having an issue staying in overdrive. Like rev bouncing on highway/growling a little in 5-6 gear. I was dumb and babied it home, but since the torque converter was the issue, the trans wouldn’t have survived anyway. It happened around 115,000 miles which typically when you’ll see trouble with the 6L80 torque converters. So got a new trans with 100,000 mile warranty. I also did a trans flush about 3,000 miles before the torque converter acted up, so don’t know if that helped lead up to the torque converter failing. I’ve always been iffy about trans flushes anyway.
Thanks for that info!
@John Brennan congratulations on this full on conversation with yourself with all your complaints. This hillbilly engineer has been working on cars his whole life, but you know, thanks for the new handle name. I kinda like it ☺️ @hillbillyengineer
They need to get Mopar into this also. So many hemi engines have gone bad for the same reason.
I used to work for the biggest distributor of GM parts in Texas. And I have delivered countless lifters to shops throughout the Houston area. Thousands and thousands of lifters. It's ridiculous that's how bad it is a lot of the times the lifters are in back order because everyone is ordering them
Good inside knowledge. It is pretty crazy and yet they just keep making it the same way
2008 suburban had a trashed cam because of this system. It looked like your picture that you highlighted.
Not sure if I've been able to avoid any future issues with the lifters, but what I did on my 09 Sierra with the 5.3L was use my friends HP Tuners module to shut off the AFM. It now only uses 8 cylinders and doesn't switch back and forth from 4 to 8 cylinders. Hope it helps.
It helps. Doesn't prevent failure entirely but it helps
This is what I did on my 2011. Best sounding 2011 engine I've ever heard.
It definitely works.
It’s going to buy time, that’s it. A full delete is the only way to ensure that the faulty parts are completely removed from the engine
I have had my afm in my 2014 silverado with 105000 miles disabled with one of those range devices that plugs in to the port under the steering wheel for 60k now and I havnt missed 4 cylinder mode ever since. Although I'm sure because of the design of the motor I'm still at risk of lifter failure
still a risk but it definitely helps!
Have you had any problems with your condenser? Mine went out and I was reading it happens in the 2014 models.
@@downsouthallah4800 yes its a very common thing on the 2014-2019
@@downsouthallah4800 I did back at 45k and I was still under warranty so the dealer fixed that for me I bought the truck in the winter with 41k on it summer came around and I was pissed I didn't have ac
The afm honestly does little to help fuel economy, maybe 1-2 mpg gain at most. It is the dumbest thing gm has ever done. The 2.7 l turbo 4 might top it in a few years though if gm continues to put it in the Silverado, it’s a doomed engine from the start.
I've been an automotive technician for 18 years and I've seen several of the gm trucks and SUV's come in with this problem Have also seen these vehicles go to the dealership to try to get repaired and they come right back with the same problem or worse the best way to fix it is to delete it and yes they should have a lawsuit for all of them
I am hoping for this to get somewhere. I love my 15' Silverado, but Im sure my lifters are a ticking time bomb. I have a Range AFM delete module and it seems to have helped a slight rattle I noticed a while back(could only hear it in V4 mode at very low RPM). But the writing is on the wall and I know it'll be an issue eventually. At 108K miles and so far nothing substantial repair wise, fingers are crossed. Love the content. Keep us updated!!!
We'll keep you updated for sure! Best of luck. I did my delete at 108K lol
@Gold Standard, I have a 2015 GMC Sierra 1500. My lifter went out in August 2021 out of the blue. Truck was at 145k miles. The dealer wanted $15k for a new engine after taxes. We were able to talk them down to $6500 with labor and tax because there was no way we were going to pay that markup. So they put a new engine, and I got the warranty 100,000 or 3 years. Long story short, I’m looking into getting the range afm delete. You’re right about the engine being a ticking time bomb. I hear a click every time I move from a dead stop sounds like it’s from the chasis and then my suspension is fine but when I go over those rough concrete speed bumps I hear an audible (can crushing) kind of sound from the front and rear suspension. And I go over those slowly lol. But yeah, keep us updated. And merry Christmas to you and your family.
my 16 silverado ticked in v4 mode for a while and eventually the lifters on the passenger side went solid and messed up my camshaft and damn near blew my whole engine.
in hopes that they don’t go bad, but if they do get the DOD delete kit from texas speed and just bypass the afm issue all together that’s what i did and the truck runs better than before!
Interestingly enough the Service Manager at my dealership told me to get the Range AFM disabler. He didn’t trust the AFM. He put the Range on his Silverado.
@alfonso merry Christmas to yours as well and best of luck with the truck!
I bought my 2021 GMC Sierra 1500 with the 5.3 liter engine January 21, 2021. In May we drove 2,000 miles to Maine. The next day the #6 cylinder pushrod failed and the engine shook like it wanted to exit the engine compartment. Took it to the local GM dealer. They had five in the shop just like mine. My truck had less than 4,000 miles on it. Only the left engine bank was fixed - the only broken part. GM wouldn’t fix the right side because it wasn’t broken. Yet. So that’s a crap shoot. The replacement time was quoted as “we don’t know” and “over four weeks” due to availability of parts, specifically gaskets. I was stunned at the amount of parts that had to be replaced. I’d really like GM to replace the lifters on the right side of the engine at their cost so I feel more comfortable that it won’t fail.
That stinks man. It is really a ticking time bomb with the newest gen
I have a 2015 silver and have not had any major issues requiring service YET, but my lifters have always been noisy. Now I do feel like they are a ticking time bomb.

Another fine product brought to you by the Great Mistake Corporation.
Non dealership engine technicians make twice as much money in actual engine shops. Then they do in the dealership. Good luck.
Depending on your transmission you can disable afm without any aftermarket devices. If you have a 6 speed put it in manual and select 5th gear, 8 speeds select 7th gear. This disables afm on 14-18 I know. I use it on my 17 Tahoe and 18 Silverado.
Good to know.
Try to remember!
Good tip, I'll be sure to mention that in some future videos.
Gm has covered/hidden this issue for many, many years. Hope everyone nails GM. They are just being cowards, they need to build better products and stand behind them. Period....
Agreed!
Why only those engines? The 3.6L V6 also has the same issue, I believe it comes along with the automatic transmissions.
Not sure why they didn't include more
What about 07-13? I have an 07 Tahoe with the 5.3L that has AFM & have spent 6K so far getting all 16 lifters replaced on 4 different occasions. Better believe I saved all my receipts!
When i researched about my oil pump issues, a guys did mention that this was gonna happen next and advised me to sell or trade if possible and man am i glad i did!
Definitely a lot of maintenance on these that should be needed in the first 150K (ideally longer)
I have a 2014 Sierra with the 5.3 with 105,000 miles on it and it has been flawless. I am starting to get a small lifter tick on it now and that worries me, I would love to get the refreshed 2022 Sierra with that new interior but I don’t know if I could trust the new ones with all these AFM issues they are having.
Same mileage as mine I switched to royal Purple oil and try to change my oil more regularly around 30% or so I change it at. The royal purple is sold in a 8 pack on Amazon too unfortunately since my last oil change the price has jumped up a bit. Anyways I had that small lifter tick mainly heard it in drivethrus next to a wall idling. Since the royal purple tho the tick has been gone. Fingers crossed
I don't trust the new ones yet. I might consider a 23 or 24 but the 22s have too many problems. Honestly tho, If the truck has been good to you, I would do an AFM delete and a torque converter swap and keep it for another 100K.
Amsoil is great too. That's all I use. I made it to 108K without any issues then I did an AFM delete.
Please drive your truck in M5 drive mode from here on out!!! It disables AFM and keeps it in V8
I had Nissan Titan 2006 Zero issue until i sold it with 227k miles, i bought 2017 Silverado 102k miles now and the lifters start tapping when the oil gets hot, transmission shudder. I will not buy any GM products, will find out Toyota tundra or go back to Nissan Titan aging.
Thank God there isn't a class action lawsuit on Cliff's beard.
rofl - not yet
Reading about all of these failures, makes me feel even more better. That I kept my 2003 Silverado, and not trade it in for a new truck. My truck at 265,000 miles and still going strong.
My buddy's 2021 blew up at 6K miles. If you trade it in, you're better off with Ford, Dodge, or the 2.7T 4 banger if you go GM (which actually isnt a bad engine so far).
I had a 2009 Silverado 1500 with a 5.3 engine. Bought it brand new. That thing would consume a quart of oil about every 1500 miles. This is quite concerning since it only held six quarts of oil. Back then I remember reading about it having something to do with the AFM system. One would think that they would have fixed the issue by now, but Im glad someone is trying to do something about it. They need to go further back than just 2014 as this has been a problem for several years prior. I know GM up'd the oil capacity to 8 quarts on newer models. But with the amount of oil my truck burned you could theoretically never have to change the oil. Just check, add, and replace the oil filter periodically.
Couldn't agree more 👍👍
ABOUT FREAKING TIME…. I had my 2014 5.3l failed at 65k miles and gm wouldn’t cover it and I had to pay for a new block and lifter kit.
That's so frustrating. As soon as I was out of warranty I deleted mine.
I'm gonna need to follow up with this. I have a 2011 1500 Silverado & just had to have the engine rebuilt due to several lifters not working & causing damage to the cam shaft as well. I love my Chevy but having to rebuild with ONLY 102,000 miles was a huge gut punch to my Chevy faith. I now have an EVAP leak that won't go away. I live in my truck with work so this is a huge crush.
I had a 2012 Chevy 1500 that I had to rebuild the engine at 95000 miles! It cost me $4800 to do! I have always been a Chevy fan but after this I was so mad I went out and bought a 2019 laramie longhorn!
Do you pump gas with the truck on? If so, evap issue fixed...
I had this happen on my 2015 5.3L at 30k miles. Luckily I caught it right away without any further damage to the engine. It took almost 2 months for the dealer in my area to get the lifters replaced because they were so backed up on repairs. While I still have the truck, I will not be purchasing another GM product with this “technology”.
2015 GMC 1500 same lifter failed twice ( #7) With in 6 months... Ended up doing a full DOD delete kit which cost almost around 4 grand in parts and labor.. I'm very interested in this law suit... My mechanic said this AFM crap has been an issue since it was first seen in the 2008.. Cant believe they have never fixed it..
Why are the 4.3L Ecotec3 not included. It has AFM/DFM?
Unsure
I had 2019 Ram 1500 that I bought new and decided in August to trade in for 2018 Silverado. The Silverado with 5.3 only had 20,000 miles on it. Within few weeks I hate driving the Silverado, just always jerking and shifts are awful. Times slowing down for light it down shifts hard. But put in low gear and shift it to 5th so it will shift normal up and down thru 1 and 5th gears and drive around and it's a totally different truck. Shifts great and has that v8 pep. But if leaving it in normal Drive gear it's so sluggish and shifts are always so strange. Days i regret leaving Ram for Chevy. I never had problems with my Rams. I know all manufacturers have there problems, wife works for Ford and wouldn't let me get Ford. She sees all problems they have with the F150 . Been wanting to get Range Technology to keep the Silverado in v8.
They all have issues sadly. Pretty telling that your wife doesn't want you getting a truck from the company she works for tho lol. They all need better quality control and better suppliers.
You must have the 8 speed trans and thats also is very common, you need a trans flush with that special hp fluid which by the way is expensive per quart
@@kennymartinez973 nope I have the 6 speed. Everything I've read and watched commen on the 6 speed. My brothers is same way and guy beside us at our seasonal camping sight is same. They both say it's always jerky and strange shifts
I just finished replacing the engine in my friends 14 Silverado 5.3 with a brand new Gm engine. The original had the dreaded noisy lifters.
I hope you did an AFM delete in it first
Its a shame older models aren't included. Many of us have well maintained older trucks (2010+) without a million miles on them that have the same stupid AFM design.
Why not on the 07-13 I wonder.
I'm currently having a lifter problems with my 2008 Silverado 5.3L.
Me too, at 116,000 miles.
Took out my 2008 5.3 at 80,000 miles. Then at 94,000 miles. On top of using a quart of oil every 1,000 miles since new. Shameful the 2008 to 2013 owners got nothing because it was still being denied and covered up back then.
Frustrating for sure. Any major issues otherwise?
@@TheSundaeDrive Both cat converters needed replaced at 54,000k $1,400 but warrantied and the oil sender went bad at 55,000k $950. Two DOD repairs @ $3,500. Tail lights all stopped @ 82,000k. $550 to rewire, circuit boards and bulbs. I gave up at DOD failure and owed too much to sell. So had to pay for 2 years while it rotted in yard and I drove my GF car. Bought anew 2018 Ram and ended my 30 years of Chevy trucks. Looks like 2021 and they are still making the same junk.
I have a 2008 GMC 5.3 Z71. With 70k on it. I have a work truck so dont drive personal truck all the time. Now you got me nervous.
I've driven GM all my life but after all the garbage I've experienced with my 2017 Sierra I will NEVER buy another GM product. My wife's Terrain is also a piece of trash. Their warantee covers nothing, they make excuses for any issue you have saying it's not covered. My advice to everyone out there, buy anything but GM!
Agreed! Couldn't keep my 2017 Sierra over a year and a half cuz of all the issues
Does anyone know some of the symptoms? I bought a GM certified 18 Silverado (5.3) with 22k miles. I've had nothing but issues since bringing it home.
The primary issue has been a sputtering that usually happens around 1500rps. It seems like the motor is cutting out. I was recommended Top Tier Fuel, which I've since switched to. I'm paying out the ass for TT Super Premium and it's still sputtering.
It threw codes a few weeks back for misfire. Since then it seems to lack power. My gramps rusted out '02 runs better.
Normally it is loud ticking sounds that indicate a failure, you have something going on for sure tho
I didn't know about this until your video. Thank you so much. My '16 Corvette thanks you, too.
🎄Merry Christmas 🎁
Just 3 days ago my 2021 Silverado High Country 1500 was put on a Flat-bed truck & sent to my local Chevy Dealer for this very same repairs! I NEED MORE ADVICE please reply?
ONE MORE REASON TO MAKE ME HAPPY I GOT RID ON MY 14 SILVERADO
Don't get me wrong, I love my truck but it does have a lot of issues. I think most trucks do they are just different
All LS based engines have had lifter issues.
This in 22 years in the making.
Hopefully it forces gm to at the very least issue a recall so those who have paid out of pocket can be reimbursed and people like myself who so far, knock on wood , havnt had any issues yet can get the faulty parts replaced without having to wait for something to go wrong and then have to pay.
Yup just waiting for it to go out aswell. Has always shifted rough
I was hoping that when ac condenser went out, paint started peeling, and oil pump went out as well it was just a matter of time before lifters gave out man!
One can hope - time will tell
I have been a GM guy since I was 17, I'm 43 and I got sick of the Lifter and Transmission issues. I decided to try a Ram and so far what a night and day difference. I wish GM would get their act together. GM use to represent reliability and strength, now its more on how fancy they can be.
Lol they have lifter and trans issue too. All makes suck now
So in the meantime should we be using the dfm or afm disablers in the obd port?
They don't prevent failure but can help prolong the life
The cateye really does look the best of any gm pickup, and the avalanche isn’t included in that. It’s not bad but it doesn’t look as good as a Silverado cateye.
Every other gm truck looks garbage to me, a clean fisheye doesn’t look bad but the cateyes look best
Good looking truck for sure.
I always favored Chevy especially the old 5.7 vortec engines...they have gone so far downhill its unbelievable
DFM is disabled in the 21 and newer model year starting from a March build date.
My 2019 Silverado z-71 with 6.2, a little over 50,000 miles, is sitting at Chevy dealership, lifters on back order. No idea when they will come in.
Does this lawsuit include the 4.3 litre V-6,they also have afm in 2014 and up models?
I do not believe it does. I don't think the V6 got afm until 2016 but not positive about that.
Why does my 15 sierra bog out when I step on the gas going into 2nd and 3rd gear?
Could be the transmission tune
What about older vehicles??? I had to rebuild the 5.3 in my 07 Trailblazer because of a collapsed lifter…
They have a ton of issues too
I own a 2007 Avalanche that had the AFM. At about 118,000 miles, I started getting error codes like traction management faults and other driveline issues. A scan showed it was all because of an issue with my #7 cylinder. Cylinders 1, 4, 6, and 7 are the AFM cylinders. I stopped driving the vehicle and started ordering parts. I ordered a new cam for a 4.8 engine, a set of 16 non-AFM lifters, a new timing chain, a non-solenoid valley cover, a gasket set, and a set of top end bolts (heads and intake manifold). My son and I did the work in our South Carolina driveway which means in October because of the summer heat and humidity. I got my parts through a GM Parts outlet, but places like Summit have AFM delete kits as well. I also had to get my ECM reflashed so it wouldn't be sending AFM error codes. It now runs like a champ at 151,000 miles. I guess mine is too old for the lawsuit.
Thanks you don’t say that the 2021 6.6L gas in the 2500HD was affected. I assume it’s not?
I don't think they have cylinder deactivation? Or do they?
@@TheSundaeDrive yes after looking it up for the 6.6 gas I believe you are correct and a couple of the smaller displacement engines in certain trim levels do not either so not sure how emissions rules vs engine longevity reconcile.
Why is no one talking about the 2022 5.3 and 6.2.?? They also have DFM. Did they fix the problem since the 2021 models,??
Not sure. Too knew to tell probably
Not the 4.3? My 2017 silverado 4.3 had lifter failure
Should have been included
I’m a technician for General Motors. Around 4 cars a day come in with this issue and it’s been going on every day for about 5 weeks now
Do you ever do any videos specific to the 2020 and newer 6.2 Silverados?
The years for Avalanche is listed 2014-2016. The last year of the Avalanche was 2013.
I was wondering about that. Some questionable dates in the lawsuit. Maybe it was produced longer overseas?
so there is no RECALL yet? Would this include Traverse as well?
I also bought a 17 new with the 6.2L. A lifter failed today at 59,105 miles. Thankfully I paid for the 7 yr, 100,000 warranty. Two local dealerships wouldn't even get me in for 3 weeks, and so I had to trek to the dealership I bought it from to get it in for diagnosis. Crazy! FJB
definitely worth having the extended warranty for sure!
So you are saying I should buy my Range AFM Disabler now on my 2008 Silverado with 160,000 miles? I am suspecting oil consumption issues and have replaced the oil pressure switch and filter screen 2x in the past 2 years.
If you can't afford a full afm/dod yes. I would probably recommend doing the range. It won't fully prevent the failure but will probably help make it last a bit longer. Not a guaranteed fix tho
My 2012 is failing because of this issue. What law firms are listed in the suit?
We linked to the articles in the description which should have have the firm info.
What about the 4.3 V6?
This engine also has AFM.
not sure why it wasn't included
What about the 2007 original afm bank 2 lifter 7 failure
Only 14s and newer included but maybe you can join the lawsuit. Link in description
I have been a chevy man for years.Built motors ,raced cars .I do own a 2018 Silverado. Love the truck absolutely can't stand the cylinders dropping off.It defeats the hole reason of owning a truck ,Everybody likes has mileage, but IT'S A TRUCK NOT A VEGA. If MY TRUCK STARTS DRINKING OIL AND LIFTERS START STICKING .SHITE GOING TO HIT THE FAN.With the right SERVICE motors should last a long time .I do have life time drive train warranty,free oil change which they SERVICE regularly.That being said oil should never get dirty to cause any lifter problem or rings ,valve guides ware. SO ITS ON THEM .SO THEY WILL REPAIR IT ,WARRANT THE REPAIR IT OR EAT IT.MERRY CHRISTMAS AND HAVE A SAFE AND HAPPY NEW YEAR! LGB!
A lifetime warranty is pretty sweet - was that a dealer thing or did you have to pay extra for that?
I just started finding out about all this and just bought a 2018 Chevy Silverado 1500 with the 5.3 about 1 1/2 months ago, I am buying a AFM disabler today for it so it doesn’t keep switching back and forth and causing premature wear, hopefully they get this fixed soon and do a recall and fix this issue
Sadly they won't. The new v8s have cylinder deactivation on all 8 cylinders and are failing even more frequently
Does performing oil changes in shorter intervals reduce the chance of lifter failure?
Possibly but lots of people commenting with short change intervals and still having the failure. I personally changed my oil 8-12K Miles and probably had to add a quart in between. I didn't have a failure up through 108K miles and then I deleted afm. Full guide up on the channel
@@TheSundaeDrive thank you for the response. So it sounds like failure is almost guaranteed just depends on at what milage.
what about the gmc, silverados 5.3 prior to 2014
Sadly I don't think it was included in this.
My friend's 2015 just went out at 105000 last month and all the service work done at dealer. He was upset because warranty run out a few thousands mile earlier. Another active fuel management fails again.
Usually GM will cover a portion of you ask when you are close to the warranty. I hope he did a delete since he is out of warranty
