My two cents...I have a 2024 Mazda CX-5 Premium. I bought it in September of 2023 as it just came into the dealership. It has the I-Stop button. Operationally, It seems to only shut the engine off when I brake harder than normal. I generally brake gently and it does not activate. If I am stopped after gentle braking and I press the brake pedal harder, the engine shuts off. As I release the brake it starts again. Seems that braking pressure is one of the parameters. I'm not sure this is normal but I actually like it this way. It's my wife's car and she loves it!

We bought a new Cx5 Premium, manufactured in march of 2024. They have neither the Istop or CDA and I like that. I got a copy of the bulletin and it stated that they stopped putting those in the Cx5 after November 2023 for the reason of chip shortage. By listening to mechanics and others, that might be the stated reason but it possibly could be due to to some problems with both.🤷 I frankly am glad that they are not on ours. Number one I don't want my engine shutting down in traffic unless I shut it down and as far as CDA, other manufacturers have tried it and what I've heard, they were problematic with cylinder issues. As far as 93 octane, unless the manufacturer recommends or requires it, I don't waste my money. Each his own though. Thanks for the video.👍
Cheap 87 Octane can cause premature detonation within the cylinders on Mazda products. Over time, can become an issue. Heard that on another UA-cam channel which went into detail on the Mazda 2.5L. A consideration if you keep car 10-15 years.
@@marktwo3160 true, it is important to use top tier fuel. Having said that, my 2024 CX 5 with the naturally aspirated 2.5 is noticeably quicker from 0-50 on 93 octane.

@@jimmy5634 Yes. You are correct. Try Avgas 120 RON like we get here in Australia and the engine becomes turbine like smooth with a LOT more oomph and far better mileage.
Our RAV4 seems to do the engine stop at every light and stop sign. We do get a message that the engine will not stop when the ac is running. This feature is odd to get used to. Not sure how the Mazda works.
I was always told growing up that starting an engine is when you get the most wear on the engine, now every new car ICE seems to think its a great idea!
For the most part that statement is talking about cold starts. Though there is no doubt that constant starting has to put more stress on the battery/charging system and the starter.
I don't have a Mazda with i-stop but from my research looking models with it, this is what I understand. i-stop is back on by default every time you start the car. The button is only used to turn it off and there should be an i-stop OFF indicator meaning it's disabled (and obviously press it to turn back on if you first turned it off). For some of the lesser known conditions, It is brake pressure sensitive (vacuum) so if you have a light hold on the brake, the car may not shut off. You also need to have your steering straight without much hand pressure on the wheel for it to activate. Sport mode also may also defeat it. If you are stopped on an incline/decline, it may also not necessarily turn off.
I have a '21 CX5 GTR Grand Touring Reserve with the turbo! Not one single problem, lots of fun, 28 mpg on the highway ( although, all of the Turbo models built in '21 & '22 have a class action recall involving changing the Valve Stem Seals ) ..just got mine back last month....and so far, no issues. If so, I'll go get a CX70
@@vlreviews The old Turbo go "bang" myth. LOL. I've owned both gasoline and diesels and all were Made in USA Garretts and were like new when I sold the cars after 10 years and 250,000KM's. Secret??? 100% full synthetic oil and oil & filter changes every 7,500 KM's (4,660 miles).

8:53 The third symbol is the engine. The idea is that there are 3 components that need to be ready for iStop to activate. The engine needs to be warm so that the restart is not causing unnecessary wear. The battery needs to be charged sufficiently to support the vehicle with the engine off. Finally, the A/C represents the idea that the vehicles interior temperature is pretty close to the temperature set on the climate control system. When the system says "Not Ready" its means that one of those conditions is not met. The most usual reason it does not activate is when the climate control settings are set to two significantly different values for the driver and passenger. (e.g. Lo for the driver, and a number for the passenger, which is the setting that I often use).
You can disable it permanently, there is a switch on the hood latch that you can unplug, and there are plenty of videos on UA-cam on how to do this, otherwise, there are modules from overseas that you can buy...
Did a test drive in a Subaru Forester, and have never driven a car with “I-stop”, and the dealer never told me it had that feature, so when it “died” at a stop light, it scared the crap out of me. Hate that feature. Will never have a car that has it.
@@VacLab I-Stop is ONLY a mechanical bonnet latch switch. It takes 20 seconds to disconnect and you will NEVER have the engine stop again! They put the bonnet latch switch in for the dealers/mechanics so that with bonnet up the I-Stop feature is 100% disabled. This is the first thing I did with our November build 2024 Mazda CX-30.
Two days ago I visited a Mazda dealership. I love the CX-5 Premium Plus. Beautiful inside and out, and has lots of great features. Just the right size for me. It goes for around $38k. But since I do a lot of city driving, the 23 mpg on the 2024 model is not what I'm looking for. I want a car with a little better fuel economy. The 2025 models have i-stop and cylinder deactivation, which increases the mpg to 26 city. But after research I see many owners don't like this feature. It's not popular, and causes problems. Cylinder deactivation & i-stop adds more complexity and maybe more repairs in the future. And just to get a 2 or 3 increase in mpg. I don't think it's worth it. For these reasons I won't buy a CX-5. Which is a shame because otherwise it's a wonderful car.
My new 2024 CX50 turbo is only getting 22mph average with premium. It also has IStop when i was told it wasnt. Im a Mazda fan but im pissed and not pleased with it. Only 2000 miles and i might return it. I never use IStop, i always turn it off because the added wear and tear on the motor is not worth it.
I'd also be keen to know if iStop doesn't activate if you have the AC running. I think that icon on the right depicts the engine itself - what it means though, I couldn't tell you lol - or that battery thing and what 'not ready' means ....
I am contemplating buying a new 2024 or 2025 CX-5. I have heard or read a few things that I will present to you based on what I have heard. I-stop is automatically on every time you crank the vehicle, the light comes on when you deactivate the function. If you want to deactivate this, you have to push the button every time you restart the vehicle. If you don't push the brake pedal down with enough pressure, i-stop does not activate. If you have the defroster, maybe just the a/c, it does not activate either. (all based on what I heard) Side note question: Have you tried your personal car with 87 octane to see if you actually get less mileage or are you just doing that based on past experience? I have heard, no personal knowledge, that premium is not required and will not improve fuel mileage when only 87 octane engines like in my 2023 Mazda3 is recommended. I have heard that these motors will not properly burn high octane gas and will cause a problem eventually whereas 87 octane would be better for it. I am not disputing what you are telling us, just asking. I don't need more power out of my Mazda3 2.5L n/a motor but if premium made it run better and was better for my engine, I would certainly give it a try. And I also ask because I still own my 2006 Mazda3 2.0L n/a and have only ever used 87 octane. Has always run fine with good fuel mileage. No complaints at all.
I get 32 mpg in my 2024 Mazda CX5 carbon edition. I live in the country. Mixed country and city driving. I have not driven on the interstate yet. Regular fuel usually 2 persons in car. I have less than 4k miles. I bought my CX5 in Nov 2023.
The benefits are at least threefold. 1) About 10% higher gas mileage 2) About 10% higher horsepower 3) Less carbon buildup in the engine Just the above makes it well worth it for me over the last 40 years, but there are more reasons as well.
I’m with you. First of all, in my area premium gas is around 65 cents a gallon higher than regular. Secondly, my 2024 has the naturally aspirated motor and I get noticeably better acceleration and about 1-2 mpg improved gas mileage. Bottom line is for about $8-10 a fill up, to me it’s worth it. People throw more money than that away on useless lottery tickets. 😂
I've got a 2024 Mazda 3. Preface - I hate iStop. Mine is always on by default after every ignition cycle so ever time I turn the car on I have to turn it off. Pain in the ass. You have to depress the brake pedal quite firmly for it to activate. My iStop button has a little light on the button so when I turn it off it lights up amber but nothing changes on the dash. If I don't turn it off and come to a stop at the traffic lights the car shuts off and the words iStop illuminate on the dash in green meaning that it has activated. They really need to switch it around so it's always off unless you want it on.
I know this sounds weird but have you checked the battery in the key fob remote? Or maybe tried the other key fob remote? My 2024 CX-5 Premium had worms in the system until I decided to try swapping out the key fobs and low and behold - no more worms. Come to find out the key fob battery was at 2.98V.
