I drive an 06 Sienna and have never had any issues or codes in 255k miles. The sliding doors both broke but I'm not lazy like many so I just operate them manually.
My 2005 Sienna just had the ignition coil #4 replaced after noticing engine idled rough and losing power when accelerating. The car has been reliable over 17 years and 318K miles. This has been the most serious issue. Previously serious issues were 1 starter and 1 alternator.
I currently have a used 2007. So far only thing that's gone bad after a year and a half with it is the break light sensor went out, but it was super easy to just pop off and swap out, no tools needed.
Still have a 07 from new, 0 breakdowns and problems so far and haven't encountered any issues from the video but it's got pretty low km's. Hoping to drive this thing for at least another 10 years.
I have a 2007 Sienna with 133k miles that i bought new. I just changed one of the 02 senors and have fixed the power door over 10 years ago. No problems yet with the MAF or coils or evap. Great van!
Outstanding presentation. 4 of 5 problems you talked about I have had. I have a very good and honest mechanic but this presentation really helps me understand better. Thanks for putting it on
I purchased a 2005 Toyota Sienna XLE in April, and I love it! However, I have noticed ALL of these issues. Lol, I'm just happy to see that they're all minor problems.
Two of my brother in laws have sienna’s. One is a 2006 and the other one a 2012. They’ve own their sienna’s for about 6-7 years give or take. Never had a serious issue beside small maintenance like oil change, spark plugs, etc.
Unless like my 2004 Siena XLE that went through 2 transmission failures . 1 at 73000 miles, another at 130000 miles. AC compressor, new radiator, the power door issue. Liked it, but unloaded it after the second transmission replacement. They're not all great.
I had an 04 Santa Fe LX for a few years before I got my 06 Sienna(it was free) and overall I liked my Hyundai more. The reliability is there in my Toyota but servicing it overall is not that fun. Lots of cheap plastic everywhere.
“The Car Care Nut” Toyota Master Mechanic has a two-part YT video on the 2004-2010 Siennas and also a Chassis Electrical video & details the primary concerns. This 1A Video is the top 5 most common issues. If you never had any of these issues you’re lucky 🍀 but don’t criticize them for offering helpful advice.
We are the original owners of out 2006 Toyota Sienna LE FWD with 193k miles. Common problems so far is power sliding doors, wheel bearings, lower control arms, and leaking valve cover gasket. We recently changed out the driver CV Axle as well. This car definitely needs more maintenance then our other cars but it constantly hauls 6-7+ people everyday and picks up our restaurant supplies at Costco weekly.
@@CJ-fh5xq yea of course it’s gonna take more maintenance then those other cars it has a lot more miles then your other cars and it’s much older then most those cars you named..
I have a 2004 Toyota sienna with 198,000 miles on it. For the last four years I’ve had an engine check light and VSC check light on the mechanics at the dealership have replaced two oxygen sensors and a catalytic converter and still have not fixed the poor gas mileage and engine check lights! About a month ago I cleaned my mass airflow sensor and disconnected the battery to reset the codes. Before I did this my van was averaging about 13 miles per gallon afterword I was getting 23 miles per gallon. But now the lights have come back on and I’m down to getting 13 miles per gallon again!
My wife’s uncle sold us his 2004 Toyota sienna xle nice white with brown interior had like 110k miles he used it just to go out with the family now its at 155k and we use it to sell at a Swapmeet and work 😂 it’s definitely seen better days but it’s an amazing van
Both sliding doors for me. Not TOO bad to replace, but if you mess it up once, it’s a waste of 3+ hrs and $160 part. Replacement part is cheap quality if it’s off Amazon, as expected. But I couldn’t bear to pay double for OEM and still risk messing it up.
I’ve had a 2008 Sienna for just over 2 years now. Have already replaced an O2 sensor, mode door actuator, both blend door actuators, heater core, crumbly plastic heater hose t-fittings, and power sliding door cable. Fingers crossed I can avoid needing the MAF sensor, or Evap Canister anytime soon.
600k?! 🤯...👍 nice! My 2005 is at 251k so this gives me hope. 🙆🏻♀️Just acquired it at 249K from my sister (original owner) and so far had to replace the original starter motor and gas cap which triggered the check engine light. All's good now and 🤞 she'll run smoothly for at least another 10k before dipping into the pockets.
Door cables and door actuators for sure. The other REALLY bad part of these cars is the spark plugs are impossible to get to----it's an all day job. Found the belts were really hard to replace as well.
Just had the rad 3:12 replaced in summer of 2023 for some reason my 07 Toyota sienna van blew off the rad filler neck wasn't sure what caused this issue but may have been low antifreeze or air bubbles. Only 117,000 miles still lots of power mechanic said will need new belt tensioner as getting noisy and new gator serpentine belt New plug wires as for some reason they move and then cause the engine light and Trac light to come on.
Waaa? Sounds like there are no problems. I have 2000 Sienna. I owned it since 135k. replaced O2 sensors soon, ignition coil, steering rack (at about 190k), windows regulators, front struts with sway bars and links, rear shock absorbers, radiator (at about 180k it will blow on any car), 100k service (water pump, timing belt), pulled out power door motor (stuck, replacement is too costly). I don't count brake drums with brake shoes replacement (once in 10 years) and I just put on second ceramic brake pads. Recently replaced alternator and 3rd battery. Voltage started to drop down to 11.8 with all auxiliaries on (AC, front rear fans, headlights). No mechanic can/wants to find what causes voltage drop and as I mentioned before I got new alternator and battery ( went through 3 reman alternators).
None of these issues on my 19 year old 06 Sienna low miles 95k only. However, OEM radiator was plastic and cracked leak. Driver door broke at hinge. Dashboard cracked like crazy. Both taken care replaced free of cost even after 10 years later by Toyota.
#6 - Thermostat 'plastic' housing that cracks along the "welded/glued" line and will leak antifreeze. If you are handy, you can do it yourself. But first buy yourself 5 small acrylic paint bottles of different colors at TARGET. Paint connectors and hose plugs in different colors because reconnecting them could be confusing. While there, replace those 2 plastic T-hose connectors with Aluminum ones - a salesman at any auto-parts store will know as soon as you tell him what you are doing. If you are not handy and you can afford it - let the qualified mechanic do it for you because it will be very frustrating at times!
We are actually having a steady low squealing sound from our 04 LE I hear it with the trans when I shift it between R & Drive but it's not on start up. Any ideas were I should look?
Love my '04 Sienna with 223,000. The only problem dont have is the sliding door issue. The sad thing is I haven't found any reputable mechanic to help with these minor issues. I'm always quoted $500 and up before they even look.
Good luck! We also have an 04 Sienna in the same mileage range, and we are among the many, many unlucky people who had the front door weld break. Have been quoted $3000 to replace the door. The problem is that the door check no longer works, so the door will swing wider than you set it for, which risks banging into and damaging someone else's vehicle. Toyota was finally forced (by the sheer number of complaints) to acknowledge the design failure and fix these, but we didn't get the notice or have the problem until after the recall had expired.
It is counterintuitive but dirty filters actually filter our more particles than clean ones. The problem with dirty filters is that at some point they create too much back pressure or break. In manufacturing plants, they sometimes have backpressure gauges to indicate when a filter is too stopped up. Meanwhile the filter is getting better and better at filtering. The logic. When a filter is new, they have holes so air can go through. They will catch particles larger than the holes. As particles partially fill some of the holes, they catch some of the smaller particles. Bottom line, dirty filters are not the cause of MAFs needing cleaning. Of course you do need to change the filter eventually or it will make the make the fuel air ratio too rich.
🙋♂️ ok so today I did some maintenance on a 05 sienna, and when I was replacing the air filter I thought it’d be a good idea to clean the MAF sensor. And of course being a klutz, I some how disconnected one of the 3 air lines that was going to the air filter cover where the MAF sensor is screwed on to, and I heard it release air like when disconnecting an air hose from a compressor (well maybe not THAT loud). I didn’t even clean the MAF sensor, and just out everything back. Turned on the vehicle and let it idle. After like 5 min the RPM dropped to around 500 but the vehicle didn’t stall. I shut it off and tried to turn it back on, nothing. Tried a second time, and now it just stays at 500. Any suggestions how to fix this blunder??
Have you done a video on the motor mount type of PWM vacuum switch valve? I can’t seem to find any decent info on which of the three hoses go where. The switch has a port on top, that I think goes directly to air filter box. Then two ports in back. I think one of those ports is a vent and the other goes to what I believe is called the actuator. It connects to a second vacuum switching valve then the actuator. But I can’t find anything online that definitely tells me which of the two back ports on the PWM vacuum switching value is to vent and goes no where. Seems to be something I should get right on my 2008 Sienna!
You can still open and close them manually, but nowhere near as easily as a manual door. We have a 2004 LE with one manual door and one power door. The manual door is super easy to operate. The power door, with the power shut off to it, is not.
I have an exceedingly silly question...can I add a driver side power sliding motor and such to a 2004 Sienna LE? I know the XLE has it but this LE came with full history and such so I went for it when I got one recently as a temp car till more EV options that fit my needs come on the market. But...not having a power sliding door on this side is becoming an issue...
Should I buy a 09 Sienna Le with 155k miles for 3k is that reasonable or should I negotiate the price lower it has no dashboard lights and interior and exterior look really clean. So I wanted to know if it’s safe to buy this car used because I have two daughters and we need a bigger car. Thanks
Only done ignition coils out of that list. Power door cables are more common than those listed. Valley plate coolant leak on the 3.3s. And #1 is probably leaking power steering rack.
I just got new kyb shocks from rock auto and had a shop replace for 700 total. Wheel bearings are next, I'm guess 700ish for a complete knuckle installed. They seem to last 75-100k.
thank you for this useful video. My 2008 Sienna has engine heating issues, I replaced radiator and water pump, but still the coolant does not circulate, the overflow tank is normal temperature and radiator is hot and a bit of coolant evaporated, what could be the issue? Also I bought this used vehicle and now it is coming up with Maintenance minder, what should I get it done in a non expensive fashion

My 05 Sienna suddenly started randomly doing the “no crank no start”. One day it will crank up and go but once I turn it off it won’t crank again for 24-48 hours. Now it is not starting at all so I have scheduled appt at dealer.
All of the sudden when I saw you. I saw you like John Malkovich.. Thank you for your great videos.. Would you please do a video for MDX Acura 07-09. ? THANK YOU
2006 Sienna with 213,000 miles and one fairly hard front end fender bender that badly tweaked the hood/fender panel alignment,. Haven't had any of these problems. Only issue is severely clouded plastic headlights. Plastic headlights should be banned. My 41 year old truck has glass headlights clear as the day they were made.
Sienna is reluctant to restart when the engine is hot (quick restart after running) No check engine light, no over heating no codes showing. Engine cools down a bit (10-15 minutes) and it fires right up on the first try. Very strange… in need of assistance 🙏🙏
VERY common problem that's hard to fix on 2004's: the driver's door check strap cup cracks, causing a popping noise when opening and closing. There was a "recall" years ago but it has lapsed. Cannot buy a replacement cup that should be welded into the door.
I have a Toyota Sienna 2006. The other day I hit like a rock on the road. It was a loud noise. I sounded serious. Found a leak. Had to replace the radiator but the van started overheating. I had the thermostat and the temperature sensor replaced but still over heating. I was told it could be the water pump or head gasket. I can drive the van for short distances until I see the temperature gauge needle go way up then i pull over and wait for the engine to cool down. Any suggestions?

I am using a Toyota sienna 2006 I washed the engine because it's too dirty I covered the alternator thou..but since then I had problems with the car whenever I start the car its vibrate hard and it's not stable..please any help..
I have toyota seinna 2006 it have a lot of codes but codes no problem slide door is not working but it’s ok main thing that AC doesn’t give good throw because of under dashboard fridge and I’m so worried about it because I’m In Dubai and weather is hot
Does anyone else chug or hesitate at hughway speeds? Mine shakes like a misfire or something while doin 70 down the highway, almost like its running out of gas.
I have an 06 toyota sienna with 62 k miles on it. Got it when it had 51k. The only problem or i dont know if this is normal when turning left or right or some sharp curves it has lots of roll. Can someone let me know if this is normal? And the gas pedal is stiff. Some one get back to me please. Besides that i love the van.
S 2005 sienna runs and starts fine but every now and then the shifter locks ,there's no power on the windows radio,horn but somehow it still runs not sure if its the computer or the brake switch took it to a few places but they couldn't find the problem?????? When it doesn't have that problem it runs beautifull
I have an issue with fueling, after $10 it’ll stop fueling at every $0.10 to $0.40 cents, please let us know how to fix it and where to fix it in Springfield, Illinois thank you,
Hey everyone, I've heard that the sienna also have issues with the gear more often.. is it really true and what's the probability of it coming up.... and can it be fixed properly?
Ok so I have an 09 sienna and I have as to replace ignition coil b 3 times in 2 year.. I’ve replaced the spark plug every time and put new wires on it the last time I did it. Here we are 6 months later and it’s giving me the same code. Anyone know why the same ignition coil keeps failing would be a huge help!!
I have a 2008 and my gas mileage is horrendous as of late. 220 miles per tank!! Ive changes the purge valve, the MAF sensor, the Charcoal canister and have done a crapload of other things as well. Air filter was done today, wasnt that bad. I dont have a clue what to do next. What the heck is going on that my gas mileage is so terrible? Anyone have a clue about this? thanks.
I got a problem with my 2004 Sienna, maybe someone can help me? Ignition key out - rad fans start working. (Not all the time, it may happens once a day or once a week) They may start any time when car locked and alarmed. Key in, ignition ON - all good. The same thing with day light. May turn ON any time when not in use. Drain battery to zero. I disconnected day light. And disconnect fans plug all the time when not driving. This happens mostly in rain season when wet. Never in dry summer. Any idea? Thanks

I had a 2007 and never had a single problem .It was the best family van we ever had.
My parents have the 07 with 325k miles. Engine had an engine overhaul at 300k due to a broken spring (didn't drop the valve). Been a good vehicle
I currently have a used 2007. So far only thing that's gone bad after a year and a half with it is the break light sensor went out, but it was super easy to just pop off and swap out, no tools needed.
Still have a 07 from new, 0 breakdowns and problems so far and haven't encountered any issues from the video but it's got pretty low km's. Hoping to drive this thing for at least another 10 years.

the fact these are very minor things that can be done in under 30 mins is pretty insane, these will last forever for sure.
The power sliding door is a 3 to 4 hour job with the pre-assembled cable unit. Otherwise, it will take at least 5 to 6 hours to complete one door.

But I can’t find anything online that definitely tells me which of the two back ports on the PWM vacuum switching value is to vent and goes no where. Seems to be something I should get right on my 2008 Sienna!
If the power side doors fail, can you simply open and shut them manually. Will they still lock?
Mine does not open from the inside but does open from the outside, its very heavy! Yes they still lock, manually and with key fob.
You can still open and close them manually, but nowhere near as easily as a manual door. We have a 2004 LE with one manual door and one power door. The manual door is super easy to operate. The power door, with the power shut off to it, is not.
I have an exceedingly silly question...can I add a driver side power sliding motor and such to a 2004 Sienna LE? I know the XLE has it but this LE came with full history and such so I went for it when I got one recently as a temp car till more EV options that fit my needs come on the market. But...not having a power sliding door on this side is becoming an issue...
Should I buy a 09 Sienna Le with 155k miles for 3k is that reasonable or should I negotiate the price lower it has no dashboard lights and interior and exterior look really clean. So I wanted to know if it’s safe to buy this car used because I have two daughters and we need a bigger car. Thanks
can you please talk about overheating issues of this 2004 modeel
Only done ignition coils out of that list. Power door cables are more common than those listed. Valley plate coolant leak on the 3.3s. And #1 is probably leaking power steering rack.
@1AAuto How to replace a 2005 Sienna Hazard Switch. Lights work, but I need to maintain holding down the button.
had the transmission replaced at 190k due to a bad radiator mixing coolant with transmission fluid
What would cause the passenger side door lock to rattle after replacing the passenger side view mirror?
Should I repair a 2008 sienna with 170k miles that needs wheel bearings, shocks and sway bar links ? Everything else is working great
Mine have 250k miles and still going ok with front shocks and lower triangles replaced
I just got new kyb shocks from rock auto and had a shop replace for 700 total. Wheel bearings are next, I'm guess 700ish for a complete knuckle installed. They seem to last 75-100k.
yes these van can go 300 plus thousand miles
Im not a mechanic but Id say definitely if it were my car. Keep that van out of the junk yard. Too much embodied energy to waste it.
Of course go for it still worth 8k
thank you for this useful video. My 2008 Sienna has engine heating issues, I replaced radiator and water pump, but still the coolant does not circulate, the overflow tank is normal temperature and radiator is hot and a bit of coolant evaporated, what could be the issue? Also I bought this used vehicle and now it is coming up with Maintenance minder, what should I get it done in a non expensive fashion
+@skbskb7596 We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Very useful info, thanks
My 05 Sienna suddenly started randomly doing the “no crank no start”. One day it will crank up and go but once I turn it off it won’t crank again for 24-48 hours. Now it is not starting at all so I have scheduled appt at dealer.
All of the sudden when I saw you.
I saw you like John Malkovich..
Thank you for your great videos..
Would you please do a video for MDX Acura 07-09. ?
THANK YOU
Siennas are great vehicles
GREAT VIDEOS! WE NEED MORE 2019 RAM1500 VIDEOS. COOLANT, BREAK FLUID CHANGES AND BATTERY.
2006 Sienna with 213,000 miles and one fairly hard front end fender bender that badly tweaked the hood/fender panel alignment,. Haven't had any of these problems. Only issue is severely clouded plastic headlights. Plastic headlights should be banned. My 41 year old truck has glass headlights clear as the day they were made.
not a word about power sliding door cables corroding out or driver door stopper mount spot welds giving up?
Sienna is reluctant to restart when the engine is hot (quick restart after running)
No check engine light, no over heating no codes showing.
Engine cools down a bit (10-15 minutes) and it fires right up on the first try.
Very strange… in need of assistance 🙏🙏
VERY common problem that's hard to fix on 2004's: the driver's door check strap cup cracks, causing a popping noise when opening and closing. There was a "recall" years ago but it has lapsed. Cannot buy a replacement cup that should be welded into the door.
Great video!! Thanks!
I have a Toyota Sienna 2006. The other day I hit like a rock on the road. It was a loud noise. I sounded serious. Found a leak. Had to replace the radiator but the van started overheating. I had the thermostat and the temperature sensor replaced but still over heating. I was told it could be the water pump or head gasket. I can drive the van for short distances until I see the temperature gauge needle go way up then i pull over and wait for the engine to cool down. Any suggestions?

Any follow up? Your transmission or oil pan got whacked? Every 90k the water pump and belts need replacing anyway
Very good know and be prepared for. Thanks for the video!
5 months later, did any of these problems happen to yours? any different problems?

DO YOU KNOW WHERE IS THE KEY FOB RECIVER/ DCR LOCATED IN 2005 SIENNA?
I have an 06 toyota sienna with 62 k miles on it. Got it when it had 51k. The only problem or i dont know if this is normal when turning left or right or some sharp curves it has lots of roll. Can someone let me know if this is normal? And the gas pedal is stiff. Some one get back to me please. Besides that i love the van.
Toyota: oh those are minor easy fixes they will last forever!
Any other brand: terrible! Never buying one again!
🤦🏻♂️
I liked working on my 04 Santa Fe LX more than my 06 Sienna. The sienna is not the easiest vehicle to maintain, throws you through hoops.
S 2005 sienna runs and starts fine but every now and then the shifter locks ,there's no power on the windows radio,horn but somehow it still runs not sure if its the computer or the brake switch took it to a few places but they couldn't find the problem?????? When it doesn't have that problem it runs beautifull
Anyone have experience their hazard light or all 4 turn signal not turning off?
2005 Toyota sienna
What about the p0500 I was told it was the electric wiring
I have an issue with fueling, after $10 it’ll stop fueling at every $0.10 to $0.40 cents, please let us know how to fix it and where to fix it in Springfield, Illinois thank you,
It’s a 2013 Dodge Grand Caravan rt
Hey everyone, I've heard that the sienna also have issues with the gear more often.. is it really true and what's the probability of it coming up.... and can it be fixed properly?
I think it was a recall about it so supposed to be fixed
Not true
It's true he didn't know that
What recall?
Thanks
Ok so I have an 09 sienna and I have as to replace ignition coil b 3 times in 2 year.. I’ve replaced the spark plug every time and put new wires on it the last time I did it. Here we are 6 months later and it’s giving me the same code. Anyone know why the same ignition coil keeps failing would be a huge help!!
Are you replacing with Denso brand?
Check fuel injectors, spark plug wires, vacuum lines, and fuel delivery system. Most likely your fix will be spark plug wires or fuel injectors.
I have a 2008 and my gas mileage is horrendous as of late. 220 miles per tank!! Ive changes the purge valve, the MAF sensor, the Charcoal canister and have done a crapload of other things as well. Air filter was done today, wasnt that bad. I dont have a clue what to do next. What the heck is going on that my gas mileage is so terrible? Anyone have a clue about this? thanks.
Old spark plugs, ac compressor issues, 02 sensors, bad power steering pump or lower power steering fluid, or a bad cv joint would be my first look.
Use a Techstream scanner to scan any bad codes. Make sure to use Toyota genuine maf .
Should make videos for bmw oil leak problem. Oil leak where has gasket
Can I get a sienna 2007 model please
no mention of oil cooler lines and timing cover leaks for the 07-10 models? those are BIG ones.
I got a problem with my 2004 Sienna, maybe someone can help me? Ignition key out - rad fans start working. (Not all the time, it may happens once a day or once a week) They may start any time when car locked and alarmed. Key in, ignition ON - all good. The same thing with day light. May turn ON any time when not in use. Drain battery to zero. I disconnected day light. And disconnect fans plug all the time when not driving. This happens mostly in rain season when wet. Never in dry summer. Any idea? Thanks
I am replacing sensors every year. When will it stop
#6 the oil cooler tube
there is a recall on it
