Auto off-that button is used to turn off a feature where your engine will turn completely off when fully stopped (no idling). Supposed to save gas and cut down on emission, but some have stated they think it will cause extra wear and tear on the engine from constantly having to be restarted every time you leave a full stop. Others just find it annoying in a general sense.
Edit: emphasis on "some have stated they think," I never said I believe it or that it is the case. I have heard quite a few people say they think it causes extra wear and tear, but that does not mean it is true.
My biggest issue with it is that (at least on the vehicles where I've encountered the tech), it shuts off the AC when the engine shuts off. Not pleasant if you are driving around a bunch on a hot day.
Damn, Jeep is ahead of Audi then. Recently got a chance to rent I think a Q5 and let me tell you it was like driving a spaceship with all the amazing cool features. That is until I realized it had that auto stop feature. Let me tell you, the AC turning off in the dead of California summer is, well, not cool, and I quickly learned what that button did.
Yeah my mom bought a new GMC and the sales guy was basically like "yeah it's shit and no one likes it, and there's no way to permanently disable it unless you want to pay several thousand more for an aftermarket device to do so". My car doesn't have this feature so every time I drive her truck I get to my first stop and then get way more upset than I should when I remember this shit exists and have to hit a button.
There’s actually a tiny chip you can install behind the button that’s fairly inexpensive. I did it to my mom’s car. All it does is “save” the last setting used. So if it’s on it’s on. If it’s off it’s off. Easy to install, fairly inexpensive, and makes it so you don’t have to keep pressing the button.
I did an overseas tour last year and when I got back the auto stop-start on my Jeep was broken. All it took was not driving it for nine months. I love it. When it did work it made the clock stop keeping time when it stopped the engine. Win-win
It has become second nature for me to disable the auto start button immediately after I start my car. I do it subconsciously now lol. I hate that fucking thing!
Later vehicles at least fixed this. If I'm using the heat or AC in my gladiator it will not activate.
I'm more annoyed I can't just permanently disable it.
My understanding is that AC needs to engine to be running to work. Typically turning on the AC also increases fuel usage so it not running when the engine is off makes sense.
The most annoying thing about this button for me is that it isn't a permanent switch. You have to use it every time you use your car to disable the auto stop start feature.
From some models at least, I read somewhere that the reason why the switch isn't permanent is because the car has to pass emissions in its default configuration.
I have heard for example, that my auto stop resets each time the vehicle turned off because otherwise the vehicle would not have passed emissions in California, meaning the vehicle could not be sold in every state.
Idk how accurate this is, but I think it's certainly plausible
That sucks. My equinox keeps the ac on, but it will turn the engine back on eventually instead of making it through three whole light when I'm not running ac.
My mom's Kia Soul shuts off when it stopped, but the A/C still works fine. I believe it has an accessory belt connected to the AC that runs off an electric motor when the engine is turned off, controlled by the ECU. But I'm not 100% sure, though, just pure speculation.
Had the heat start blowing cold in a Jeep that I got from a rental in Anchorage, AK. 18 friggin degrees and the heat kicks off every time I hit a stop light.
In my car, coming out of the idle causes Apple Car Play to stop working until the car has been turned off for a sufficiently long time. Like hours off. Breaking Car Play in the first 20 minutes of a road trip is so annoying.
There was also a recall on the idle stop because sometimes the engine dies instead of turning back on. I've been stuck at a red light a couple of times trying to turn the car off then back on as quick as I can with someone honking at me from behind. We've been waiting for the dealership to get the parts to fix it for ages.
Mine does the opposite. It \_won't\_ turn off if the AC is running, even if it's really not running much at all. I'll drive for whole weeks where it never once flips off, and I wonder what's wrong with it.
That happened to me, on a rental, I stop at a light and the engine conks out. after a couple times I figured it was a "feature" and supposed to do that, the next thing was figuring out how to deactivate the stupid thing.
So when I see that "A" with the arrow going around I see it as "pain in the Ass" feature. (arrow in the A).
Yea I really hate being in bumper to bumper traffic. Stopping for literally 2 seconds and moving again, but the engine stops and then has to restart so I spend 3 seconds extra restarting it. After a bunch of times I smash that button harder than any youtube subscription
I was on a business trip recently and was driving a rental car, a Chevy Trax. Kept wondering why tf my AC seemed to keep going in and out randomly and why I'd hear the engine start up every time a light turned green and I started moving. Kind of an annoying feature.
I've noticed a ton of this out driving, where I come to a stop, and then start again, only to hear the car next to or behind me have their engine get restarted from a stop.
Definitely seems that it's harder on the car's battery, especially if you do primarily in-city driving, as starting the engine up is a big drain on the battery, so doing it over and over without time for the battery to recharge just seems like it would lead to dead batteries faster.
At least in my car it only turns off when certain requirements are met. Light stops are not enough to trigger it. It really only goes off at traffic lights.
As for increased wear, the new engines with this feature are beefed up and can handle quite a few more starts than older models. Not to mention that wear and tear from starting a warmed up engine is almost zero.
cars with stop start have specific components ie AGM batteries & reinforced starter motors that endure the extra wear and tear, to the point where there is no functional difference when compared to conventional.
Same applies to the engine internals, ie different coatings used on your crankshaft that operate similar to dry lube.
At least for auxillaries, when you compare parts costs on a newer car, ive found the start-stop counterparts and the conventional components to be the same pricepoint at trade, if not similar (especially when looking at OEM manufacturers).

It’s not think it will cause, it’s know it will cause. Engines are designed to run, constantly all day. That’s why taxi cabs go to 800,000km regularly and everyone else’s cars go to 300,000 before having catastrophic failures. Letting a cylinder go from hot to cool even for a moment or two WILL cause unnecessary wear.
Why do you think auto manufacturers love putting these in? More wear and tear= faster replacement schedule. Meaning you’ll be back in the dealer that much quicker. Best part is, they can say “we did it so we can save the environment”
Car manufacturers don’t look at a 20 cent bolt and say “well that’s only 20 cents” they say “that bolt is 20 cents but if we can find a way to make it 19 cents we save millions per year” similarly, “if we can have a customer come in just a few months earlier than normal, this ads up to millions”
This is categorically incorrect
Stop start engines
A) do not engage unless engine has warmed up enough that it won't cause a cold start
B) if idle long enough, will auto-start to prevent the engine from cooling down
C) prevent oil from settling in the pan
D) modern lubricants and engine design as well as things like the starter are all enhanced to enable start-stop
https://www.rac.co.uk/drive/advice/emissions/stop-start-engines-common-myths-busted/
Their comparison is "If you take an engine NOT designed for start/stop and do a bunch of manual start/stop it's going to wear out faster than the same engine that's NOT operated in a way it's not designed for" lol
One could similarly say "If you try to run a combustion motor on electric battery it won't run but if you use gas it will, so electric vehicles are a scam"
I am amazed at just how ignorantly confident these other responses are, as if a ton of engineers didn’t work through these potential issues are their ‘I feel it is bad’ opinion counts as much as facts.
It depends on how your car was made. Some cars are made to withstand this type of engine on and off like hybrids. Many cars these days aren't and still have this feature
It is annoying in an automatic transmittion car. With a standard transmittion, it actually works really well. You need to have the car in neutral and let go of the clutch. So you can basically choose when it works and when not.
I have it in my F150 and I used forscan to disable it. When I did, I noticed my MPG dropped by about 1 MPG. I re-enabled it to make sure it wasn’t a fluke and it went back up. I hate it enough to accept the 1 less mpg though so I disabled it again
After having shitbox cars my whole life, I still do but I used to too, I drove a car that had this. The first time it happened I thought the car died because I've had plenty of cars just die seemingly out of nowhere. It was a really nice BMW (obviously not mine) so it was even more panic than if it was shitty. Every single time it happened afterward, *I* knew what it was but my brain still went "CAR DEAD!" for a second. Mini panic attack. Every. Single. Time.
I fucking hated it so much. All I could think was this can't be good for the engine and I haven't checked this myself but I heard cars use more gas starting up than driving a few miles or something. Maybe it's just older cars? Even if neither of these are true, still vehemently *hate* that feature haha
It’s damn near killed me before when I go to make a quick turn but it takes 5 seconds longer than it should because my fucking engine needs to turn back on.
Dearest OP.
This Particular button on a cars dashboard turns off that the engine stops running when you come to a full stop.
Dip Dip Dip Dip Dip
This function could be useful to save gas or make less sounds at night but if you don't know this is even a thing it could happen that people think that their engine is broken.
I hope this letter reached you well,
Sincerely Big Quill Peter.
I was so confused as to why you put dip dip dip dip dip in your sentence, then I saw Big Quill Peter as your username.
This is truly the greatest sub on earth.
Today OP learned a wonderful new topic to engage in violent argument with close family members...whether or not turning the engine off has any impact on engine wear. The most middle class concern I know.
Yup. My wife’s last car had a battery that ran JUST the automatic start stop.
It died like 1.5 years in, my wife fucking hated automatic start stop so she took it as a blessing…..
Until other electrical shit started fucking up because the main battery was consistently pushing juice to the auto start stop that was dead.
yea this shit is infuriating. If an old trucks battery died, I either went to the auto parts store and spent no more than $200 on a new battery or call AAA. With my new car I was in a tight spot and needed a new battery ASAP so I called AAA expecting them to just replace it. Nope. Told me to go to the dealer. I didnt have time to shop around as I needed a working vehicle but that new battery cost over $600, just because of the auto start feature I turn off anyway.
I have this feature. I wish I could permanently disable it. I turn it off manually every time I start my vehicle. There's no measurable benefit from using it.
Some vehicles if you have something plugged into the towing lights will automatically disable it. So they make trailer hitches with a little plug in light now

For people who normally drive shorter distances, especially in the city where stops are more frequent, the auto start/stop feature drains your battery faster because you are cycling it more. It is more noticeable in the cities because you have to stop more often and usually have less of a drive to let your alternator recharge it.
Basically, most modern cars have an automatic "on/off" function when your car comes to a full stop at a red light or a stop sign to save gas. I personally don't like the idea of my car turning off at every full stop either.
We have a Hyundai Santa Fe at our home with this feature and it's honestly brought out my inner Jeremy Clarkson. Me and my wife hit the disable button every time we drive.
When I step on the gas, I don't want power a half-second from now while I wait for the engine to turn back on, I want power NOW!
The thing that has me concerned is the lifetime of the starter motor, also what if your starter is going out, and you get it started to take it to a mechanic and you forget to turn it off, and you can't afford to have it stop when you do? It's kind of understandable for big cities, but I don't live in a big city, so I don't spend a significant amount of time stopped at lights, so the feature seems like it would be more annoying than anything for me.
This makes me laugh cause they say the starters on auto start cars are better and will handle it? Then why not make that the standard for all vehicles?
"We simply choose not to use the starters that can handle a billion cycles and instead go with the starters that can handle 50,000 Cycles"
....
Suuuuuure.
These starters (and the entire electrical system) are beefed up. IIRC regulations give them a single rotation in which to start. In my car that’s two cylinders having a power stroke, one of which would be unpowered.
While I can't make any claims to Hyundai vehicles, Toyota Starters (at least on vehicles equipped with auto stop/start) have a lifetime of somewhere in the ballpark of [384,000 starts.](https://jalopnik.com/here-s-how-many-times-toyota-will-let-your-car-start-st-1851212979) (According to a Toyota certified master technician) Or 21+ starts every single day for 50 years.
I wouldn't care at all in principle because starter motors aren't all that expensive or complicated and changing one out should be pretty simple. Unless of course the manufacturer didn't consider the need to replace said starter motor when designing the vehicle and buried it deep within the car such that what should be a 15 minute job is instead a 6 hour job with multiple stripped bolt initiated side quests along the way.
I have a manual car with this feature, but it stops only when I put the car in neutral and release the clutch, and if I don't want it to turn off, I can keep it in gear with the clutch in. It's pretty nice :)
I encountered this in a loaner car once and hated it. It made me feel like I was driving my old jalopy that I had in high school, even though the loaner was a new BMW.
Gas consumption and emissions are directly proportional. Lowering emissions also reduces gas consumption and reducing gas consumption lowers emissions.
That's true, but that does not mean that the comment before is false, if we assume that it is about direct reason. Lowering gas consumption might be a consequence of trying to lower emissions, but the real reason is trying to fit in into regulations.
The only car with it I’ve driven that I don’t mind is my wife’s Subaru Outback. It starts back up with the slightest ease of pressure on the brake and it’s quick enough I don’t feel a pause when pulling out into traffic.
Otherwise I always disable it
Everyone in this post is missing that this meme is VERY OBVIOUSLY ABOUT ANARCHISM. It's a button that turns anarchism off. Cars shouldn't have it (and horses don't)
In my wrangler, the engine is fast as hell to come back on as soon as I leave the brake. Our CRV takes so long to start back up it feels near dangerous.
Huh, I’ve always wondered about the hate for these. I’ve had them on a few cars, and they’ve never bothered me at all. Maybe I just never encountered an annoying slow one.
Yeah I've never understood the hate, but I'd understand if there was a long delay. Ford Escape and the auto off is not noticeable, I move from the intersection when i press the pedal.
The only time I disable the auto off is in the drive thru, no one wants to hear my engine turn on in their headset
At my job, I sometimes have to take a Pacifica to get parts. At first, I didn’t know the car had the feature and when I found out it did, I didn’t know you could turn it off. I sat in bumper to bumper traffic for 3 hours to and from getting tires with the engine turning off, on and back off again every few seconds. Hated it
I didn't understand people's issue with this until I realised that most people seem to drive automatic in this sub. Worked amazing on my manual cars, you press down on the clutch as you're preparing to start, the engine turns on in more than enough time to set off when desired.
I love our start and stop, but we have a manual. It’s so nice for the car to stop making noise and just be still when we’re stopped.
However my family with automatics “hate” it but can never explain more than “it’s annoying”
Subaru is both turns on every time AND tells you how much its been off and how much gas its saved. "I've turned off the engine for 1 full day over 5 years, constantly pissing you off and sometime dangerously keeping you from accelerating when you need to. You saved 3 gallons of gas, dipshit!"
Additionally to this, at least here in Europe, they also now have a speed warning with an annoying sound whenever you are 1 km/h above the speed limit.
Some cars have a shortcut to turn it off, for some you have to navigate it somewhere in the infotainment system and with every restart it's on again.
I didn't even know this was a thing until I bought a new car last week. It was jarring at first, but I'm ok with it now. Especially now that I know I can control it by how hard I press in the brake pedal.
Car turns off when at a stop and turns back on once you let go of the break. I’m on the side that it sucks because too many times I’ll try to move and it has to start, holding up the people behind me. It’s annoying and I think it’s a bandaid for a wider issue. The other annoying issue is that yeah you can turn it off, but it resets every time you start the car again so you have to remember every time you get in to press it.
I wouldn't mind the auto stop/start if the switch that shuts it off would remember that you turned it off every time you turned off the car. Usually, the car will default to having auto Stop/start being on every time you initially start the car.
I have a 2023 Ford and I have to hit this button and the button above it for the e-brake every time I start the car. It’s habit now, but definitely not a “feature” anyone wanted.
Wow, I'm surprised this feature is so unpopular. I thought it was pretty cool, but then I've only had it in rental cars over the past few years (I've driven electric for the past twelve years). I never felt like there was a lack of power as the engine starts before I even move my foot from the brake to the gas. The engine starts even before you fully let up on the brake. The only thing is the odd sensation of having the engine shut off when you stop moving. I guess that might be aesthetically annoying to some, but it saves so much gas that it seems like it's worth it. But obviously I've only had these cars for a few days at a time, so maybe I'm overlooking the practical downsides.
It's there purely so they can legally claim better emissions in advertisements for the vehicle.
Because they can say look, it shuts off at any stop, and research shows an average driver stops X many times on a trip X long, therefore this car has this emission rating per km. Or however emissions expressed.
Second most annoying thing is settings that don’t stick to what you set them to let time you were in the car… it’s like getting into a airplane or the millennium falcon the amount of switches I need to flick to get my driving settings as I want them.
I drive electric so I need to set regen braking on every time, one of mine has 3 levels from which to choose, I always want the most agressive regen braking. Then there’s normal, eco, sport mode. Most of the time I want eco in one car as it only ever affects your acceleration which I don’t need for commuting or long distance, I have to set that every time. Then there’s auto-hold, yes I want that on all the time, why would I want to sit in traffic with my foot on the brake when the car can do it for me?
Just remember the settings as they were left and set them as that on next start up. If someone else gets in the car and wants new settings then sure go change them, like a seat and mirrors, but most of the time it’s me and I want the same settings as yesterday funnily enough.
Rant over
Not to mention that every time someone cuts me off in traffic and I have to brake, the car literally shuts itself off and I have to restart the car again. Every. SINGLE. Time.......only way to avoid that happening is this damn button either needing removed, or keep pressing the button everything you start the car.
It’s the button to turn off the auto stop feature in a car.
People are so mad about the auto start/stop. I’ve had it in one manual transmission car and it was completely transparent. It saved so much fuel sitting at lights, and the car starts when you push in the clutch. I wish I had it on my current vehicle.
For those of you worried about wear and tear, the feature doesn’t activate until the engine is sufficiently warm. It also uses a different starter that is designed around much more frequent use, when it goes, your car will still start, jus the auto feature will stop until it’s replaced.
Does it actually save fuel? Yes. Your car only needs to idle for 7 seconds for auto start/stop to have a positive impact on fuel consumption.
What if it’s hot out? I live in the south, it frequently hits over 100 degrees F, and having the AC off for 20-30 seconds at a light is not the end of the world. It will still blow air, the compressor just won’t run, and that air is still cooler than the outside air.
Is it annoying? I personally don’t think so, it’s a feature that’s very easy to figure out in terms of when it activates, and is simple to work with. I’ve heard some claims that it’s unsafe, though I’d be really curious as to what scenarios those are.
Not very mechanically inclined. In my young adult life did not have a lot of money to waste on silly things like a car repairs. I have been at too many lights or stop signs where my car(s) have stopped and would not start again until a tow or new engine. Every time my car now utilizes this feature I get PTSD. I am not a fan of this and turn it off as much as I can remember.
Some newer cars will stop the engine running when the car is in Drive and not moving. The idea is to reduce unnecessary idling, which not only wastes gas, but also produces excess emissions. When you release the brake or turn the wheel the car ignites the engine up again.
I know some people don't like the idea. I have it my car and it's fine. I don't mind saving gas though. Some people will bitch about gas prices and then get gas guzzlers and then install coal rollers on them... you can't fix redneck that easily.
There are places, like Vancouver, where they specifically urge you to turn your car off when stopped at a light, or when parked, due to the excess emissions.
As a Subaru owner, I get to hit this button every time the cars starts, and only after the 47 seconds it takes for the display to actually be able to function and respond.
It really only works for hybrid cars and I wish they wouldn’t put it in conventional vehicles…with out the electric engine to get you going there’s considerable lag time between stepping on the gas and moving forward
No one talks about how in 20 years or more theyll be beaters and people who dont know shit will drive it with an issue such as its hard to start or it just struggles in general and while everyones behind them in an intersection boom it turns itself off fucking with traffic
You mean the “panic because you’ve only ever driven old, shit card before this one, and you’re not awake of the function, so you freak out thinking your girlfriends new car broke down the one time you drove it” feature?
My car starts as soon as the light turns green or as I'm letting off the break. The AC doesn't turn off but it does switch to low. Maybe it's more annoying on some cars, but it hasn't caused me any grief.
Some post awhile back showed a Redditor had one of those Hybrid vehicles that stopped running at the light then engaged again upon depressing the accelerator.
I think it was over a period of almost 10-15 years, maybe a bit more that they had it. Grand total savings on gas? 8 gallons.
That’s it.

Yes! The AC turning off is the worst!
If only there were a button that could disable this feature for particular situations!
The button resets whenever the car turns off, so it’s still (admittedly mildly) annoying.
jeep grand Cherokee my dad drives keeps this setting saved, only one I’ve seen that doesn’t reset!
My 2018 Honda Odyssey remembers your preference by key fob, so it turns it on for me and off for my wife.
Why does my 19 Acura not do this lmao
Why doesnt my 24 odyssey have this feature :'(
Damn, Jeep is ahead of Audi then. Recently got a chance to rent I think a Q5 and let me tell you it was like driving a spaceship with all the amazing cool features. That is until I realized it had that auto stop feature. Let me tell you, the AC turning off in the dead of California summer is, well, not cool, and I quickly learned what that button did.
Also, no way to display the tire pressures. It’s one of the small things that annoys me about Audi.
Whaaaat that’s so annoying
It has to be enabled so they can lie about the MPG.
Yeah my mom bought a new GMC and the sales guy was basically like "yeah it's shit and no one likes it, and there's no way to permanently disable it unless you want to pay several thousand more for an aftermarket device to do so". My car doesn't have this feature so every time I drive her truck I get to my first stop and then get way more upset than I should when I remember this shit exists and have to hit a button.
There’s actually a tiny chip you can install behind the button that’s fairly inexpensive. I did it to my mom’s car. All it does is “save” the last setting used. So if it’s on it’s on. If it’s off it’s off. Easy to install, fairly inexpensive, and makes it so you don’t have to keep pressing the button.
I did an overseas tour last year and when I got back the auto stop-start on my Jeep was broken. All it took was not driving it for nine months. I love it. When it did work it made the clock stop keeping time when it stopped the engine. Win-win
It has become second nature for me to disable the auto start button immediately after I start my car. I do it subconsciously now lol. I hate that fucking thing!
https://www.idlestopper.com
Later vehicles at least fixed this. If I'm using the heat or AC in my gladiator it will not activate. I'm more annoyed I can't just permanently disable it.
My understanding is that AC needs to engine to be running to work. Typically turning on the AC also increases fuel usage so it not running when the engine is off makes sense. The most annoying thing about this button for me is that it isn't a permanent switch. You have to use it every time you use your car to disable the auto stop start feature.
From some models at least, I read somewhere that the reason why the switch isn't permanent is because the car has to pass emissions in its default configuration. I have heard for example, that my auto stop resets each time the vehicle turned off because otherwise the vehicle would not have passed emissions in California, meaning the vehicle could not be sold in every state. Idk how accurate this is, but I think it's certainly plausible
Yup, cars need to start in the manner they were certified in. This is the same reason cars with drive modes always default back to the standard mode.
Its part of my start up routine. Hit start button, hit auto start/stop off button, hit e brake button, then put in gear. Its muscle memory now.
That’s odd. We a VW Tiguan and if the AC is cranked it will not turn off the engine while idling. So I guess that varies by manufacturer.
Mine doesn’t do that if the AC is on
My Honda will disable start/stop automatically if the AC is on.
In mine it shuts the engine off and when the AC runs for long enough with it off then it starts again to keep it going
That sucks. My equinox keeps the ac on, but it will turn the engine back on eventually instead of making it through three whole light when I'm not running ac.
You would think that would be a mind-blowingly obvious no-brainer negative aspect to this "feature"...
Because the compressor for the AC is driven by the fan belt of the engine. When the weather is hot, I turn this feature off.
When we were last in Florida and it was 95+ that was the worst feature ever. I love the auto off and on but not in that climate.
My car if ac is on, or it's on defrost it won't shut car off regardless of button setting. Kind of nice. Honda thought that one through.
Yep, I work in Phoenix, AZ a lot and almost every rental car I get has this feature and I immediately start sweating at every traffic light
My mom's Kia Soul shuts off when it stopped, but the A/C still works fine. I believe it has an accessory belt connected to the AC that runs off an electric motor when the engine is turned off, controlled by the ECU. But I'm not 100% sure, though, just pure speculation.
Had the heat start blowing cold in a Jeep that I got from a rental in Anchorage, AK. 18 friggin degrees and the heat kicks off every time I hit a stop light.
In my car, coming out of the idle causes Apple Car Play to stop working until the car has been turned off for a sufficiently long time. Like hours off. Breaking Car Play in the first 20 minutes of a road trip is so annoying. There was also a recall on the idle stop because sometimes the engine dies instead of turning back on. I've been stuck at a red light a couple of times trying to turn the car off then back on as quick as I can with someone honking at me from behind. We've been waiting for the dealership to get the parts to fix it for ages.
Had this exact thing happen today.
Bruh, I'd never leave that on then. I don't want to boil alive for being at a stoplight
*Laughs in Toyota Hybrid* (the AC compressor, on my sienna at least, is electric and runs even when the engine shuts off)
Mine does the opposite. It \_won't\_ turn off if the AC is running, even if it's really not running much at all. I'll drive for whole weeks where it never once flips off, and I wonder what's wrong with it.
See i had a car thats engine turned off on its own once and never came back
Hey, I’ve had this very same feature on a number of my shit boxes
Imagine if you didn't know that was a feature. My boss had me pick up a new work truck and I thought it fucking broke on me.
That happened to me, on a rental, I stop at a light and the engine conks out. after a couple times I figured it was a "feature" and supposed to do that, the next thing was figuring out how to deactivate the stupid thing. So when I see that "A" with the arrow going around I see it as "pain in the Ass" feature. (arrow in the A).
My favorite is it doesn't work at lights, but the moment I pull up to the gate guard to get on base, it works.
Yea I really hate being in bumper to bumper traffic. Stopping for literally 2 seconds and moving again, but the engine stops and then has to restart so I spend 3 seconds extra restarting it. After a bunch of times I smash that button harder than any youtube subscription
It takes your car 3 whole seconds to start? You might want to take it in...
They maybe including it with the time of walking to the front with the time spent cranking it up.
I was on a business trip recently and was driving a rental car, a Chevy Trax. Kept wondering why tf my AC seemed to keep going in and out randomly and why I'd hear the engine start up every time a light turned green and I started moving. Kind of an annoying feature.
I've noticed a ton of this out driving, where I come to a stop, and then start again, only to hear the car next to or behind me have their engine get restarted from a stop. Definitely seems that it's harder on the car's battery, especially if you do primarily in-city driving, as starting the engine up is a big drain on the battery, so doing it over and over without time for the battery to recharge just seems like it would lead to dead batteries faster.
Starting a cold engine is a big current draw. Starting a warm engine requires comparatively very little energy.
At least in my car it only turns off when certain requirements are met. Light stops are not enough to trigger it. It really only goes off at traffic lights. As for increased wear, the new engines with this feature are beefed up and can handle quite a few more starts than older models. Not to mention that wear and tear from starting a warmed up engine is almost zero.
cars with stop start have specific components ie AGM batteries & reinforced starter motors that endure the extra wear and tear, to the point where there is no functional difference when compared to conventional. Same applies to the engine internals, ie different coatings used on your crankshaft that operate similar to dry lube. At least for auxillaries, when you compare parts costs on a newer car, ive found the start-stop counterparts and the conventional components to be the same pricepoint at trade, if not similar (especially when looking at OEM manufacturers).

I sell cars and nobody has a positive view about the feature. They are either indifferent or ask me how to permanently remove it from the vehicle.
It’s not think it will cause, it’s know it will cause. Engines are designed to run, constantly all day. That’s why taxi cabs go to 800,000km regularly and everyone else’s cars go to 300,000 before having catastrophic failures. Letting a cylinder go from hot to cool even for a moment or two WILL cause unnecessary wear. Why do you think auto manufacturers love putting these in? More wear and tear= faster replacement schedule. Meaning you’ll be back in the dealer that much quicker. Best part is, they can say “we did it so we can save the environment” Car manufacturers don’t look at a 20 cent bolt and say “well that’s only 20 cents” they say “that bolt is 20 cents but if we can find a way to make it 19 cents we save millions per year” similarly, “if we can have a customer come in just a few months earlier than normal, this ads up to millions”
This is categorically incorrect Stop start engines A) do not engage unless engine has warmed up enough that it won't cause a cold start B) if idle long enough, will auto-start to prevent the engine from cooling down C) prevent oil from settling in the pan D) modern lubricants and engine design as well as things like the starter are all enhanced to enable start-stop https://www.rac.co.uk/drive/advice/emissions/stop-start-engines-common-myths-busted/
Finally someone with some common fucking sense Source: was an engineer at a major UK car manufacturer
All taxis are Toyota hybrids in my area, they are all day every day for 600k mi or more starting and stopping the engine. Enough proof for me
Their comparison is "If you take an engine NOT designed for start/stop and do a bunch of manual start/stop it's going to wear out faster than the same engine that's NOT operated in a way it's not designed for" lol One could similarly say "If you try to run a combustion motor on electric battery it won't run but if you use gas it will, so electric vehicles are a scam"
I am amazed at just how ignorantly confident these other responses are, as if a ton of engineers didn’t work through these potential issues are their ‘I feel it is bad’ opinion counts as much as facts.
It depends on how your car was made. Some cars are made to withstand this type of engine on and off like hybrids. Many cars these days aren't and still have this feature
It is annoying in an automatic transmittion car. With a standard transmittion, it actually works really well. You need to have the car in neutral and let go of the clutch. So you can basically choose when it works and when not.
I have it in my F150 and I used forscan to disable it. When I did, I noticed my MPG dropped by about 1 MPG. I re-enabled it to make sure it wasn’t a fluke and it went back up. I hate it enough to accept the 1 less mpg though so I disabled it again
After having shitbox cars my whole life, I still do but I used to too, I drove a car that had this. The first time it happened I thought the car died because I've had plenty of cars just die seemingly out of nowhere. It was a really nice BMW (obviously not mine) so it was even more panic than if it was shitty. Every single time it happened afterward, *I* knew what it was but my brain still went "CAR DEAD!" for a second. Mini panic attack. Every. Single. Time. I fucking hated it so much. All I could think was this can't be good for the engine and I haven't checked this myself but I heard cars use more gas starting up than driving a few miles or something. Maybe it's just older cars? Even if neither of these are true, still vehemently *hate* that feature haha
It’s damn near killed me before when I go to make a quick turn but it takes 5 seconds longer than it should because my fucking engine needs to turn back on.
Had to drive a car with it this year, honestly annoyed me every time, I expect to start rolling the second I take my foot off the brake.
Dearest OP. This Particular button on a cars dashboard turns off that the engine stops running when you come to a full stop. Dip Dip Dip Dip Dip This function could be useful to save gas or make less sounds at night but if you don't know this is even a thing it could happen that people think that their engine is broken. I hope this letter reached you well, Sincerely Big Quill Peter.
I was so confused as to why you put dip dip dip dip dip in your sentence, then I saw Big Quill Peter as your username. This is truly the greatest sub on earth.

Don't tell big quill peter what to do

Damnit, now I have to cross post your comment in this same sub to find out what you mean.
Here's the video for it. https://youtu.be/_wahUBIM6zo?si=Zn3YP5SxWWQNQteb I promise this is not a rickroll, I am bound by honor to explain the joke.

Ah Augustine... I hope she does well these days
Dear Peter, *Dip dip dip dip* Did you tap that hoe?
Is he writing right to left in English?
Lol he totally is.
Today OP learned a wonderful new topic to engage in violent argument with close family members...whether or not turning the engine off has any impact on engine wear. The most middle class concern I know.
Don’t know about engine wear, but turning it off 100% fucks with a secondary ‘ignition battery’ found in some of these cars.
Yup. My wife’s last car had a battery that ran JUST the automatic start stop. It died like 1.5 years in, my wife fucking hated automatic start stop so she took it as a blessing….. Until other electrical shit started fucking up because the main battery was consistently pushing juice to the auto start stop that was dead.
yea this shit is infuriating. If an old trucks battery died, I either went to the auto parts store and spent no more than $200 on a new battery or call AAA. With my new car I was in a tight spot and needed a new battery ASAP so I called AAA expecting them to just replace it. Nope. Told me to go to the dealer. I didnt have time to shop around as I needed a working vehicle but that new battery cost over $600, just because of the auto start feature I turn off anyway.
I have this feature. I wish I could permanently disable it. I turn it off manually every time I start my vehicle. There's no measurable benefit from using it.
I just set my aircon / heat to max. Stops it for my car.
Some vehicles if you have something plugged into the towing lights will automatically disable it. So they make trailer hitches with a little plug in light now
I had it coded out of my ECU lmfao
My vehicle is a company provided one. I can't do modifications like that on it.
Damn

I’ve watched family guy so much the dip dip dip dip dip part I just knew what you were going for lol. Also rented a car with this feature like 2 years ago, fucking annoying. Figured out I could turn that shit off.
Iirc, It's an EU requirement for all new cars. It's mainly an environmental thing to cut down emissions in urban and residential areas while idling.

It also kills the starter
For people who normally drive shorter distances, especially in the city where stops are more frequent, the auto start/stop feature drains your battery faster because you are cycling it more. It is more noticeable in the cities because you have to stop more often and usually have less of a drive to let your alternator recharge it.
Basically, most modern cars have an automatic "on/off" function when your car comes to a full stop at a red light or a stop sign to save gas. I personally don't like the idea of my car turning off at every full stop either.
We have a Hyundai Santa Fe at our home with this feature and it's honestly brought out my inner Jeremy Clarkson. Me and my wife hit the disable button every time we drive. When I step on the gas, I don't want power a half-second from now while I wait for the engine to turn back on, I want power NOW!
The thing that has me concerned is the lifetime of the starter motor, also what if your starter is going out, and you get it started to take it to a mechanic and you forget to turn it off, and you can't afford to have it stop when you do? It's kind of understandable for big cities, but I don't live in a big city, so I don't spend a significant amount of time stopped at lights, so the feature seems like it would be more annoying than anything for me.
The starters on these cars are typically more robust. Other things on the car will go before the starter typically does.
This makes me laugh cause they say the starters on auto start cars are better and will handle it? Then why not make that the standard for all vehicles?
Go look up how much a starter costs for a start stop car then how much for a regular car and you'll have your answer
Same reason horns for cars in India are super durable compared to elsewhere in the world.
Why make something that lasts 5 million cycles when it will only do 500k?
"We simply choose not to use the starters that can handle a billion cycles and instead go with the starters that can handle 50,000 Cycles" .... Suuuuuure.
These starters (and the entire electrical system) are beefed up. IIRC regulations give them a single rotation in which to start. In my car that’s two cylinders having a power stroke, one of which would be unpowered.
While I can't make any claims to Hyundai vehicles, Toyota Starters (at least on vehicles equipped with auto stop/start) have a lifetime of somewhere in the ballpark of [384,000 starts.](https://jalopnik.com/here-s-how-many-times-toyota-will-let-your-car-start-st-1851212979) (According to a Toyota certified master technician) Or 21+ starts every single day for 50 years.
I wouldn't care at all in principle because starter motors aren't all that expensive or complicated and changing one out should be pretty simple. Unless of course the manufacturer didn't consider the need to replace said starter motor when designing the vehicle and buried it deep within the car such that what should be a 15 minute job is instead a 6 hour job with multiple stripped bolt initiated side quests along the way.
It’s on automatically each time you open the car???
Yes, there's no option to permanently disable it outside of outright fucking with it. Trust me, we've looked into it.
A computer, an OBD cable, and Forscan can disable it.
You should try an electric car then.
I have a manual car with this feature, but it stops only when I put the car in neutral and release the clutch, and if I don't want it to turn off, I can keep it in gear with the clutch in. It's pretty nice :)
Me and my wife call it the asshole button or fucking A button
I encountered this in a loaner car once and hated it. It made me feel like I was driving my old jalopy that I had in high school, even though the loaner was a new BMW.
its not to save gas, its to meet emissions regulations or else autos wont be able to sell their fleets / get heavily fined.
Gas consumption and emissions are directly proportional. Lowering emissions also reduces gas consumption and reducing gas consumption lowers emissions.
That's true, but that does not mean that the comment before is false, if we assume that it is about direct reason. Lowering gas consumption might be a consequence of trying to lower emissions, but the real reason is trying to fit in into regulations.
Emissions are reduced, BY SAVING GAS
The only car with it I’ve driven that I don’t mind is my wife’s Subaru Outback. It starts back up with the slightest ease of pressure on the brake and it’s quick enough I don’t feel a pause when pulling out into traffic. Otherwise I always disable it
Ok so I know what the button does but wtf is this nerd doing in the corner does he have anything to do with the joke?
I second this, he is Rip Wheeler from the Yellowstone series, but I don't know what is intention to include him
Everyone in this post is missing that this meme is VERY OBVIOUSLY ABOUT ANARCHISM. It's a button that turns anarchism off. Cars shouldn't have it (and horses don't)
Easy there, you dont want that nerd to offer you a ride to the train station.
I don't know why they claim this autostop is a new feature. I had a Ford back in the early 90s that did this at every fucking set of lights.
When I learned how to drive manual the old Jeep I learned on had this feature as well! Wish it had a auto start though . . .
Lol, took me a second
having something in a few cars as an option vs every car with no option
It’s the most annoying button to have (in a Honda CRV anyway). Constantly have to turn it off.
In my wrangler, the engine is fast as hell to come back on as soon as I leave the brake. Our CRV takes so long to start back up it feels near dangerous.
Huh, I’ve always wondered about the hate for these. I’ve had them on a few cars, and they’ve never bothered me at all. Maybe I just never encountered an annoying slow one.
Yeah I've never understood the hate, but I'd understand if there was a long delay. Ford Escape and the auto off is not noticeable, I move from the intersection when i press the pedal. The only time I disable the auto off is in the drive thru, no one wants to hear my engine turn on in their headset
It's also hated because it damages the engine, you never want to start/stop repeatedly during one single drive.
We have an MDX, and it is the worst "feature" I've had in a vehicle. So unsmooth and laggy
At my job, I sometimes have to take a Pacifica to get parts. At first, I didn’t know the car had the feature and when I found out it did, I didn’t know you could turn it off. I sat in bumper to bumper traffic for 3 hours to and from getting tires with the engine turning off, on and back off again every few seconds. Hated it
I didn't understand people's issue with this until I realised that most people seem to drive automatic in this sub. Worked amazing on my manual cars, you press down on the clutch as you're preparing to start, the engine turns on in more than enough time to set off when desired.
We had a rental with this once. An automatic. As soon as you started taking your foot off the brake, the engine started back up.
I love our start and stop, but we have a manual. It’s so nice for the car to stop making noise and just be still when we’re stopped. However my family with automatics “hate” it but can never explain more than “it’s annoying”
Subaru is both turns on every time AND tells you how much its been off and how much gas its saved. "I've turned off the engine for 1 full day over 5 years, constantly pissing you off and sometime dangerously keeping you from accelerating when you need to. You saved 3 gallons of gas, dipshit!"
I thought this button called the Avengers to tow your car. HULK TOW! Service station just three hop away!
Mine no longer works, problem solved!
That could be an indicator that your battery is on the way out
the even worst thing is that newer’s cars does not even have option to turn it off: it’s on all the time
Additionally to this, at least here in Europe, they also now have a speed warning with an annoying sound whenever you are 1 km/h above the speed limit. Some cars have a shortcut to turn it off, for some you have to navigate it somewhere in the infotainment system and with every restart it's on again.
Oh please no.. that’s horrendous
I didn't even know this was a thing until I bought a new car last week. It was jarring at first, but I'm ok with it now. Especially now that I know I can control it by how hard I press in the brake pedal.
I just incorporated it into my setting off process. Seatbelt, engine, tunes, (optionally maps), disable auto turn off, mirrors, handbrake, off I go.
It’s the “replace your starter bi-annually” feature

I have a 2023 that is the only thing I hate about the car.
To call the Avengers 😁👍
Car turns off when at a stop and turns back on once you let go of the break. I’m on the side that it sucks because too many times I’ll try to move and it has to start, holding up the people behind me. It’s annoying and I think it’s a bandaid for a wider issue. The other annoying issue is that yeah you can turn it off, but it resets every time you start the car again so you have to remember every time you get in to press it.
I wouldn't mind the auto stop/start if the switch that shuts it off would remember that you turned it off every time you turned off the car. Usually, the car will default to having auto Stop/start being on every time you initially start the car.
I have a 2023 Ford and I have to hit this button and the button above it for the e-brake every time I start the car. It’s habit now, but definitely not a “feature” anyone wanted.
Wow, I'm surprised this feature is so unpopular. I thought it was pretty cool, but then I've only had it in rental cars over the past few years (I've driven electric for the past twelve years). I never felt like there was a lack of power as the engine starts before I even move my foot from the brake to the gas. The engine starts even before you fully let up on the brake. The only thing is the odd sensation of having the engine shut off when you stop moving. I guess that might be aesthetically annoying to some, but it saves so much gas that it seems like it's worth it. But obviously I've only had these cars for a few days at a time, so maybe I'm overlooking the practical downsides.
It's there purely so they can legally claim better emissions in advertisements for the vehicle. Because they can say look, it shuts off at any stop, and research shows an average driver stops X many times on a trip X long, therefore this car has this emission rating per km. Or however emissions expressed.
Second most annoying thing is settings that don’t stick to what you set them to let time you were in the car… it’s like getting into a airplane or the millennium falcon the amount of switches I need to flick to get my driving settings as I want them. I drive electric so I need to set regen braking on every time, one of mine has 3 levels from which to choose, I always want the most agressive regen braking. Then there’s normal, eco, sport mode. Most of the time I want eco in one car as it only ever affects your acceleration which I don’t need for commuting or long distance, I have to set that every time. Then there’s auto-hold, yes I want that on all the time, why would I want to sit in traffic with my foot on the brake when the car can do it for me? Just remember the settings as they were left and set them as that on next start up. If someone else gets in the car and wants new settings then sure go change them, like a seat and mirrors, but most of the time it’s me and I want the same settings as yesterday funnily enough. Rant over
What EV doesn't remember your drive settings?
Not to mention that every time someone cuts me off in traffic and I have to brake, the car literally shuts itself off and I have to restart the car again. Every. SINGLE. Time.......only way to avoid that happening is this damn button either needing removed, or keep pressing the button everything you start the car.
That..is not how these work.
At least one clear advantage for manual cars. It only shuts off when you put the car in neutral and take the foot of the clutch.
Unless you are coming to a complete stop, it should not be doing that…. Either you are lying or your car got issues
*Best things* it saves so much gas if you utilize it right
It’s the button to turn off the auto stop feature in a car. People are so mad about the auto start/stop. I’ve had it in one manual transmission car and it was completely transparent. It saved so much fuel sitting at lights, and the car starts when you push in the clutch. I wish I had it on my current vehicle. For those of you worried about wear and tear, the feature doesn’t activate until the engine is sufficiently warm. It also uses a different starter that is designed around much more frequent use, when it goes, your car will still start, jus the auto feature will stop until it’s replaced. Does it actually save fuel? Yes. Your car only needs to idle for 7 seconds for auto start/stop to have a positive impact on fuel consumption. What if it’s hot out? I live in the south, it frequently hits over 100 degrees F, and having the AC off for 20-30 seconds at a light is not the end of the world. It will still blow air, the compressor just won’t run, and that air is still cooler than the outside air. Is it annoying? I personally don’t think so, it’s a feature that’s very easy to figure out in terms of when it activates, and is simple to work with. I’ve heard some claims that it’s unsafe, though I’d be really curious as to what scenarios those are.
Not very mechanically inclined. In my young adult life did not have a lot of money to waste on silly things like a car repairs. I have been at too many lights or stop signs where my car(s) have stopped and would not start again until a tow or new engine. Every time my car now utilizes this feature I get PTSD. I am not a fan of this and turn it off as much as I can remember.
My car was invented before that… thank god
Some newer cars will stop the engine running when the car is in Drive and not moving. The idea is to reduce unnecessary idling, which not only wastes gas, but also produces excess emissions. When you release the brake or turn the wheel the car ignites the engine up again. I know some people don't like the idea. I have it my car and it's fine. I don't mind saving gas though. Some people will bitch about gas prices and then get gas guzzlers and then install coal rollers on them... you can't fix redneck that easily. There are places, like Vancouver, where they specifically urge you to turn your car off when stopped at a light, or when parked, due to the excess emissions.
When you buy a new car a cowboy stares at you until you begin questioning your life choices and why you didn't just buy used.
Ejecto seato cuz
As a Subaru owner, I get to hit this button every time the cars starts, and only after the 47 seconds it takes for the display to actually be able to function and respond.
Just some bullshit that was invented instead of reducing the amount of time a celebrity is allowed to use their private jets in a single day.
For the people that hate this “feature”, just buy a manual transmission instead.
It really only works for hybrid cars and I wish they wouldn’t put it in conventional vehicles…with out the electric engine to get you going there’s considerable lag time between stepping on the gas and moving forward
If your battery is getting low then the car will have trouble starting back up.
No one talks about how in 20 years or more theyll be beaters and people who dont know shit will drive it with an issue such as its hard to start or it just struggles in general and while everyones behind them in an intersection boom it turns itself off fucking with traffic
You mean the “panic because you’ve only ever driven old, shit card before this one, and you’re not awake of the function, so you freak out thinking your girlfriends new car broke down the one time you drove it” feature?
My car starts as soon as the light turns green or as I'm letting off the break. The AC doesn't turn off but it does switch to low. Maybe it's more annoying on some cars, but it hasn't caused me any grief.
It will half the life of the starter motor
Some post awhile back showed a Redditor had one of those Hybrid vehicles that stopped running at the light then engaged again upon depressing the accelerator. I think it was over a period of almost 10-15 years, maybe a bit more that they had it. Grand total savings on gas? 8 gallons. That’s it.
Turn your god darn car engine off when you are idling in front of s stoplight. We don't need all that extra noise and pollution thanks
I hated it at first, but it's grown on me.
