Mazda i-STOP - Start-stop system

i-stop improves fuel economy, reduces emissions and also reduces idling noise when the vehicle is stopped. Learn about the specific conditions under which i-stop automatically turns the engine off while the vehicle is stationary, and then restarts the engine to resume driving.

i-STOP is available for all carlines (if equipped).
* Features may vary per country.

I have the CX30 touring Mazda, I bought it new, and I found that if you lift the hood or bonnet you can disconnect the stop-start by sliding a wire along that is buy the catch that opens the bonnet, you don't need to take the wire off completely, this will disconnect the terminal, my Mazda is the 2023 model and I did this in April, The wire is under a plastic cover you just pull the cover off with your fingers gently and you will see the wire, you don't need any tools, I don't take any responsibility if something goes wrong, my Mazda does not have any trouble with the stop-start disconnected. Most Mazda dealers will say that you can't disconnect the stop-start switch it is more BS from the dealers. Thank you, Google for helping solve this problem.

I just bought a 2021 Mazda CX-5, and the salesman told me that the head mechanic at the dealership said, it doesn't have the iStop in the CX-5s in the U.S., but they do have it in the CX-5s in Japan. That's GOOD! Because I hate the iStop. More great news... it has an auto trans, not a CVT trans, and w/ the turbo engine, it doesn't have Cylinder Deactivation. I'm happy all around.

Jam the cancelation button in by wedging something into the side of the button after you've pushed it. I have not had to worry about it since. Every time you start the car it will register that it's been pushed. When it becomes time for my CX-5 battery to be replaced I'll install a SUPERCHARGE GOLD PLUS MF75D25L. It's suited for standard and i-stop cars. The amount you save on fuel with i-stop is outweighed 100 fold by the extra battery specific and starter motor costs. Hope this helps.

0:09 "... Also reduces idling noises when the vehicle is stopped." Yeah, that always puts me in panic mode, because I always think that the engine has stalled. 😅😅

The I Stop function can be eliminated without to much trouble...One has to simply pop the bonnet and relocate the micro switch that is in behind the bonnet latch ...Just remove the small screw that holds it in place and lay the switch away and cable tie is so as to not get damaged and all will be perfect...Such a relief to have my Mazda as well as my Suburu void of the insane feature ....My cars now assume the bonnet is open when infact it is closed...

I love my new Mazda 3, but hate the istop function, Mazda should allow the driver to switch the function off permanently until the system is switched ON again by the driver.

If someone says, the iStop doesn't use the starter to restart the car after the iStop turns it off, they're lying. The starter still aids in the restart at the traffic light or stop sign, etc.. IMHO, the iStop puts added wear on the engine at every restart before the oil is pumped back into the engine from the oil pan. There's also more wear on the starter and the battery. Saying different wouldn't be rational.

Battery warranty for Istop vehicle is half that for non Istop. Also at 2nd service the dealer will tell you that the battery will need replacement, even if you don’t use the Istop.

Really nice features like fuel economy meter etc that we don’t have in USA, but find it odd the AC can’t be in min position for i-stop. I keep my AC at min to increase engine stops but I also have a Chevy, not a Mazda

Question: Is it ok to have istop on during slow traffic? To stop for 20 seconds and start again the stop again for about 5 seconds or so and start again then stop for 10 seconds and start again. Is that still ok for the engine to go on and off over and over again in such short period of time? Thanks.

Do all mazda cx-5 in USA have i-stop? I have watched all YT video's and no mention of it til this video??

How can i best change my mazda car radio from Japanese to English?

[lalalanster]

I hate this function. I feel like it strains the starter too much. I live in the Philippines and traffic here is horrendous

Minimal fuel saving & hard on the motor?

[zypus]

I do not like istop function that will stop for a few second and then resume engine operation again which will not make sense. If the engine will stop for 2 second, the system shall ignore the pause engine mode. This is useful when it turns pretty low temp aircon and low fan and pause engine for 1 mins. Mazda shall fix this software to have the minimum engine pause 30 sec prior to restart of the engine.

[Arcusinoz]

I HATE the Istop it is very annoying and serves no function as the alleged fuel savings are negated by the cost of replacing the the Starter motor etc I have had a 2017 2018 2019 Mazda, but they need to listen to their buyers and have an option to turn the stupid thing off permanently not just every time I start up????

I was about to check the CX30.Upon learning that this i stop feature is part of this vehicle, I change my mind right away and stop going to the dealership.I will be looking for my other car options.

[aussie]

I-STOP works, it’s stopping me from buying a new CX5 😂

[johnrobboe]

I think this information is not correct for an automatic, I had to keep my foot on the brake and the engine started when I removed my foot. Somebody need to check their

[bahhaziz]

It's a stupid feature that will only wear out the engine and starter 🤷
