One of the newer GM safety features is Extended Parking, which automatically shuts off a vehicle’s engine after a certain period of time while the vehicle is parked. The goal of the feature is to reduce emissions and prevent potential carbon monoxide poisoning in an enclosed space. However, some owners might wish to disable Extended Parking, thereby preventing a GM vehicle from shutting off the engine when parked.
The GM Extended Parking feature automatically shuts off the engine when the vehicle is parked for 20 minutes and the key fob is not present, or after an hour when the key fob is present.
Disabling the feature is accomplished by pressing and holding the engine/vehicle start button until the driver information center displays the message “automatic shutdown off.”
This doesn’t work on all GM vehicles, but more so on the newer ones, especially those running the automaker’s new Global B electronic architecture which first debuted on the 2020 Cadillac CT5, followed by the 2020 Cadillac CT4, Chevy Corvette C8, 2021 Buick Envision, and the 2021 Chevy Tahoe, 2021 Suburban, 2021 GMC Yukon and 2021 Cadillac Escalade.
GM began to implement the Extended Parking feature as a safety measure spurred by the introduction of keyless electronic ignition. The feature is now standard on 2019 model year and newer Chevrolet, Buick, GMC, and Cadillac models with keyless ignition, also known as push-button start.
Some cases where drivers would want to disable Extended Parking / automatic engine shutoff include:
- Leaving pets in the car with the A/C running on a hot day while tending to errands (though GM Authority does not recommend doing this)
- Leaving the engine running to keep the vehicle’s climate control system active for any other reason
- Waiting in extended lines for something like a COVID test
- Needing to keep the vehicle’s climate comfortable, such as when conducting surveillance or nature photography

It’s about darn time they told us how to bypass this feature. I was told it could not be done!
I’m trying to adjust my timer from 10 to 50 minutes where my car is.in park &. Turned off
Service bulletin #21-NA-228 Full Size Trucks Idle Time-out Disable
I assume you meant to hold the button when the engine is off. Didn’t work for me, and I tried it with both the engine on and the engine off. Is there an alternate method to turn this noise off? I didn’t see anything in the settings screens
I Tried holding the button with engine on and or off no luck ,,really could use some help on my XT5 2019
So far, every vehicle I’ve tried it’s worked…I get in the vehicle, put my foot on the break, press and hold the start button down. The vehilce will start as I continue to hold the button down. It disengages the Automatic Shutoff after few seconds.
I have a service dog, I was told 2 days ago by GM support that this was not possible in a GM vehicle so I started looking at Ford products that I could turn on secure idle.
I will be looking to confirm this works on a 2022 Yukon.
a corvette bud could have used that as he parked his corvette in the garage and forgot to shut off the engine and he and his wife both died. when you get older something else happens and you forget what you were going to do. did you ever walk into a room and forget why you went there ??
I’m ok with this feature, except on my wife’s 2019 Terrain, not only does the engine shut off, the doors also unlock, never to lock again until you lock it with the key fob, I was told this was part of the 20 minute shutdown.
Never really saw advantage push button start over a keyed switch when you still have to carry a fob? I heard of a couple went to dinner and guy used push button. Went to go home and couldn’t find fob. Turns out wife had her fob in pocket book whole time. His was at home. He never had it. Thought he lost it.
These electronic key fobs are idiotic in many ways.
Just give me a key.
right on, a key has worked fine for 100 yrs ck
It hasn’t been a hundred years since keyed starts as we know them have been used.
By I’m sure back in 1949 some Luddite was saying something similar.
More crap needing to be replaced. In addition to the push button start its all cool technology only needing to push a button but not really necessary and will only cost a ton to be replaced in the future.
I think another “feature” that needs to go away is the electronic parking brake. I literally didn’t use it the first month I had my Camaro because I couldn’t quite figure out how to use it (I eventually did some intuitive thinking and now have been using it). I wanna “grip and rip”. Luckily I still drive my Cobalt daily so I wouldn’t lose touch of the good ol’ lever. In fact, Toyota and a few others have put the handbrake lever back into their newer vehicles.
EPB is needed because the computer needs to be able to apply the parking brake as a safety feature due to other features. These include stop-and-go adaptive cruise control/Super Cruise, autonomous emergency braking, self-parking and long-duration hill-hold assist (which itself is needed for auto start-stop).
The park brake needs to apply and/or the transmission needs to go into park (which implies an auto with e-shift) if somebody gets confused and leaves the vehicle while it is being temporarily stopped by these systems.
It’s also needed to auto-apply on hills on the high-GVWR full size pickups to save the park pawl. (Commercial trucks don’t have a park position for this reason)
Also, for performance applications, if you use a motor to actuate the service brake pads, you can delete the parking brake pads and drum which lets you make bigger and better primary brakes, as well as saving some unsprung weight.

Yes, go back to the key as other comments suggested. With modern day technology there should be options to turn these options on or off. The only thing wrong with keys is you can’t shut off key or door chimes. Nothing like trying to listen to the radio with the doors open while doing outdoor activities. Yes, let the drivers decide their options.
I believe my ’55 Chevy had Lock, Off, On and Start? You could take key out in Off and restart without key if I remember correctly? I could be wrong cause was 40 years ago.
Car owners should be making these decisions.
Disable option for every function like this is a must.
Next, need to know how to permanently disable the AUTO-STOP.
Range Technology RA005B
Also, the T1 full-size trucks have a calibration that can be flashed by the dealer to disable idle shutdown. TSB 21-NA-056 gives instructions.
Well, there is just another good reason that I will never buy a used car. Who in their right mind would leave a car running for a long period of time unless it’s an extreme emergency! Idling for a long period of time will just fowl your oil and should I mention the pollution and waste of gas, furthermore in some cities it against the law! GM should have had this years ago!
Might be against the law in Edmonton, Alberta, but when parents are out in their cars and trucks to pick up the kids and it is 40 below the law against idling is universally ignored.
I have associates at work that go out to their cars during their lunch hours and literally sit in them with the engine running the whole time. That is 5 hours per week of unnecessary idling. It drives me crazy, but it is ultimately their car and they will end up paying for it in both fuel and repairs in the long run. Idling laws here only apply to vehicles 10,001lbs+, so they aren’t breaking any laws. Even if they were, who is going to be around to enforce it?
Bad ice storm, have AC inverter hooked up to my Chevy Volt to power the wood stove fan to keep us alive with no power for over a day so far. Tired of waking up at all hours to go turn the car (parked outside) back on, or jumping it after the 12 volt batter is drained. So I did a search and found this thread. Yes there can be a need to turn the feature off!!!! And with a Volt, or Bolt no fouling of the spark plugs while on battery power. Which lasts a long long time.
People using the available power outlet in the bod….for starters….
I been idling mine daily for years lol I was staying in a camp in the winter for work and there was nowhere to plug in so it idled for almost 2 weeks 🤷🏽
Go buy a Prius
ABSOLUTLY not buying any Vehicles with auto stop/start. Will shop elsewhere.
Good luck not finding that feature on a new vehicle. You probably still want a CD player.
About 60 percent of vehicles have start/stop. Shop around. GM chip shortage issue has several vehicles lacking start/stop. BONUS! “Just in time” ordering of chips is “Almost in Time”. I did find a nice Lexus without start/stop. I wonder how much stopping and starting causes oil pressure to drop and cause extra wear on lubricated engine parts.
Ok so we now know how to bypass that feature can someone tell me or is bow to keep the radio going while the car is off and parked. I have gone through all the settings and can’t seem to locate where to do this. It sucks when at a ok concert or tailgating and the radio shuts down after 10 min. I know you hit the button for accessory but the radio in our 2018 equinox will only play for approx 10 min.
Push and hold the start/stop button without the brake for 10 seconds. The ignition will go ON and it will play indefinitely. Just make sure if it’s dark to turn off the automatic headlights or it will kill your battery.
Super surprised to see so many talking about ditching push button start. I had it on my previous vehicle and I thought it was a nice feature..current car is a 13 Impala. The key doesn’t bother me one bit to be honest. I guess I don’t have a preference. But those dam e-shifters! I could write a book…
The people that are commenting negatively about push button start obviously have not set up the passive lock option. This totally beats a key in the fact that you can leave the key fob in your pocket. When you walk away the doors automatically lock. I have a 2016 Impala and the fob still looks brand new because I never have to push the buttons on it.
As a retired truck driver I can tell you these “auto shut downs” have been around for many years . We usually found ways to bypass this though . However every new model would seek new ways of stopping the idle time . Let me tell you In the Dead of winter sitting in a blizzard with wind chills at 40 below or worse , there needs to be a better way . Maybe set up a system that allows a bypass of the auto shut down feature but make it a bit of a pain in the ass to do so . That way we’d only do it when actually necessary . Just a thought to digest .
Some of you guys are confusing push button auto shut off vs start stop in this thread. Amazing.
And then we have people saying they want to go back to keyed ignitions? What are you all smoking? In one press, I can park my car and have it shut off at the same time, hop out, and press the lock button on my door, without ever taking my fob out of my pocket. Why must people insist in living in the Stone Age when it comes to modern day enhancements. Weird.
You are obviously one of those people that think because somethings different. It’s better it’s people like you that believe anything they’re told.
Don’t want want a fob. Cell phone is good enough
2021 Buick Envision…. Does it matter if the car is already started when I hold it in or do I begin holding it in from the off position? I tried both ways and I’m not seeing the message? Maybe it’s not available on the new Envision or maybe I’m just a dope?
The vehicle needs to be OFF. Press the start button and hold in for 10 seconds WITHOUT pressing the brake.
Unfortunately, I’m just dumb I guess. I can’t get it to work. I get pop-ups on the display, but not for automatic shut off. Driver memory settings and such. No matter how many times or different ways I try, nothing for automatic shut off. I’m raising the white flag.
I was very interested in this as it did bite me in the a$$ one time. I went into a store while my wife sat in the Envision with our kids. I was in there longer than expected and the car shut off on them. I had the key in my pocket. Would have been nice if that didn’t happen, but also a one-off situation that is very unlikely to happen again.
That did it, thanks!
I tried this but it still doesn’t work on my 2020 At4. Do you have any other suggestions?
I have a 2023 Acadia. I was excited to find a way to stop the extended parking feature, however pushing the start/stop doest work for my car.
I think I have found a way around it as I bring the dog everywhere I go.
Open the driver’s door, start the car, activate the emergency brake, put it in neutral (push and hold, can’t just press it) set the ac and it will run. I have gone 35 min so far. I will feel more comfortable after I go over the one-hour mark. If it works for you and runs more than one hour let me know?
This doesn’t work on my 2021 Yukon.. wish it did…
Annoying Features on vehicles. Must save fuel!
emissions as the car can not put out emissions when the engine is not running. all these regulations are about global warming.
You have to hold the brake down to accomplish this. The article writer should put this into the instructions.
I run emergency lights that i plug into the Cigarette lighter outlet on my roof on my 2020 Encore GX for different reasons in Warren MI and when i activate them they work well. My problem is when I open either door they turn off is there something I can disable so they don’t turn off when i open my doors. Thanks for any help
Try pressing the start button without applying the brake pedal. This will activate the accessories without starting the vehicle.
It’s ridiculous that they put an auto shut off on with out the option to permanently disable. I have a 2022 2500 with push button start, which I do love, that is used as an emergency responding unit. Currently the vehicle shuts off on emergency scenes when it is left running for longer than 20 minutes. My truck shut down, emergency lights and radios included, while operating on the scene of a MVA. I have to go restart the thing every 20 min. Ridiculous. I have tried the fix mentioned above with no luck. I’m open to all options at any cost to shut this God forsaken feature off.
When holding the button down for auto shut off because a pet is in the vehicle. Do you still have to leave the key Fob In there to keep it running after the feature was disabled?
Not sure if this question was asked but does this permanently disable it, or do you have to do it every start? Thank you.
I have a 2020 GMC Yukon, and that method doesn’t disable the feature. Is there another way?
Didnt work on mine, 2021 Denali 3500HD. any recommendations?
It’s a kid killer pure and simple. Who really cares about emissions if your car shuts off while parked but you needed air conditioner to run to keep kid cool. Should be a lawsuit…allow owner to permanently disable so the car doesn’t override what parent sees as protecting child. And for those of you who want to say you shouldn’t leave your kid in the car never had a kid that only falls asleep while driving…or can think creatively.
Is this a one time thing? or do I have to do this every time I go to an accident for emergency on the hiway, and need the truck to run, to keep the emergency lights working?
Does not work on my 2021 GMC Denali 2500.
I have a 2023 Acadia AT4. I was excited to find a way to stop the extended parking feature, however pushing the start/stop doest work for my car. I think I have found a way around it.

Does not work on a 2024 Sierra Danali 2500HD Duramax. Went to dealer today and it is a $175 option.
I have tried just holding the start/stop engine button and holding the brake and the start/stop engine and I still cannot shut off the auto shutdown. I have a 21 GMC Sierra and I work security jobs so its nice to have AC or hear depending on the weather. Even my dealership where I bought the truck told me they wont turn it off. I said well thats just dumb! How in the heck do you shut it off? Its so frustrating!!
Dumbest option these idiots could come up with like the auto shut off when you come up to an intersection who is the idiot who thought this was a good idea I’d like a baseball bat and bash their head in
Who is this bonehead who wrote this article you have the problem with so many people is just because somethings new they think it’s a good idea another option even if it’s a pain in the ass to them is a good idea cause they were told it is 2023 elevation I think it’s a piece of junk and would never buy another one. Too many idiots think giving you another option is a good thing. Maybe they should pull their head out of their ass and figure out how to fix the steering column that keeps coming apart.
I have a 2021 rs blazer loaded and still unable
To get the extended run auto shut off to quit working, tried everyone’s suggestions about put foot on brake/ off brake and push start and wait until it says off or for 5 to seconds that others say when it doesn’t say
