How to leave truck running without it shutting off

I have a 2019 AT4 like all the new GM Trucks with a fob instead of a key after about 10 minutes of running it shuts itself off. This is by design due to people driving  other GM’s home and parking in the garage and leaving the car running by accident. GM did this to all the fob vehicles. I have a service dog, I don’t always want the hassle with people of taking him in places so I need to leave him in the truck with the AC on. If you take the fob with you you get about 10 minutes before it shuts down. If you leave the fob in the truck it will continue to run for about an hour, which is more than I ever need. I would rather not leave the fob in the car even though I can lock it with the remote but not the door buttons, even if I didn’t my 80 lb dog would scare most people off. I have been told that this can be disabled with the Tech II but I needed more info before going to ask the dealer, I don’t expect them to know how to do it. (By the way I don’t have a garage so no safety issue there).

It does not work very well it shuts down after 10 minutes too no matter what they sayI have tried it. It will restart if I remember or am close enough like not in the back of a grocery store. I don’t want to screw around with remote start, I want to be able to leave my truck running If I want to. I did it all the time with my 2014. I know the solution hoping someone has an idea on the settings in the Tech II.

I've tested mine several times. I get 15 minutes from each remote start. Do you use the OnStar app? You can remote start from anywhere with a data connection.

You can get 15 minutes each time but not 30 minutes, it will shut off after 15 and you need to restart. I’d contact a company like Viper, you can program their remote starts to run longer and they also have a fob that you can see that your truck is running.

I have the same issue. Leaving dog in the car with out the AC running is not a good thing. My old tech 2001 wasn't a problem but the new ones that shut off every (10 minutes on a 2015 Buick) is an issue.

Got to be some work around as police K9 units need them to keep running.

Would be nice to hear of something that can be done.

Also didn't know if you left fob in car that it would run longer. Good info.

A buddy of mine just showed me a trick the other day. If you repeat the remote start procedure within 30 seconds you will get 2 start cycles without it shutting off. It should give you 30 minutes of run time.

You are correct, but why should I have to turn off my truck get out and use remote start that’s stupid. I don’t want a work around I want a fix. I just leave my second fob in the truck that’s a work around and it works for an hour.

Not sure how it would work on our trucks with the fob but I know police units used to have a switch they could flip, turn the key to off, pull the key and get out and it would keep the unit running indefinitely. Might call around to some shops that work on emergency vehicles. 

 

If your looking for a solution through factory GM hardware I'm sorry but your probably not going to find it. I haven't tried it but I do not think the truck will lock with a fob still inside.

GM sells a wireless keypad to lock and unlock the truck. Its 125 bucks and has 2 way tape on the back.

 

Mount it inside the fuel door- too bulky to stick on a door. Lock truck with fab inside.. use keypad to unlock when coming back.

 

Outside of 3rd party work arounds, that would be the cleanest fix i can think of.

I had the same issue with my dog recently traveling cross country. We rented the 2021 suburban. We were told and it did work, to when you first start the vehicle to hold the start button till message came up on the DIC. cant remember what it said but something about auto shutoff disabled. I hit ok and that doubled the time to 30 minutes. We set the timer on our iPhones and would just come out of the restaurant to reset if needed. I dont have my new 2021 Sierra here to check but this did work on the suburban. Good luck.

I have at Trail Boss Custom with Key.  I too would like to just press my remote start function on the key fob before I shut the vehicle off to keep the vehicle running instead of turning off then remote starting.  My last 2 vehicles were able to do this and it is great for just running into the store quick.  It is a function that has purpose.  I don't really need longer than 15 minutes.  Is there any way to do this or any hack to get this function?

      I like the idea.  I would pick diesel if I had a choice. I need pictures though.

      Help purchasing a touch screen digitizer

      By newdude · Posted

      I've installed cheap eBay new aftermarket digitizers before.  They work.  Did a bunch of Cadillac CUE (aka Cadillac's MyLink) for someone years ago.  They all worked fine after the repair.    That number 22740886, that is a component part # for GM.  You can use it to search, but its not something that's obtainable at the dealer level.     So pretty much any of these will work - 2015 Colorado Digitizer for sale | eBay

      Exhaust heat while towing!

      By fondupot · Posted

      You can install tailpipes that direct the exhaust sideways vs the OEM one that goes straight back. There are several on the market, do you own research. HOWEVER, you need to make sure the Venturi vents are still intact, otherwise it will throw a engine code. There is a sensor somewhere that detects back pressure on the exhaust. And if it doesn't collect the correct metrics, it will throw the truck into limp mode.

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      "Teardown" is complete. Head surfaces are clean and ready, new intake is prepped and ready. Coolant drained and water pump is removed, radiator is removed, new hoses and pump are ready.   The replacement intake is also from a '95 (with I think 260k, the odometer said). Noticeably less pitting where it covers the rear coolant passages. I'm not sure if that's a tribute to more frequent use, more frequent coolant changes/upkeep, or if the intake was machined at some point. But it appears I found a good one.   My coolant hoses were original, and the lower hose still retained the factory spring inside. It's not really rusty, but it's got deposits all over it. Unsure if I should re-install it (will thoroughly clean it first). Someone said hose technology has gotten better since 1995 (has it?) and I don't need the spring. I think modern EPDM is what made those hoses last from 1995-2026, so it's a question of how much suction can the water pump really pull, and will it collapse the hose without a spring?   I'm stopped and waiting for parts, however.   When I first brought the truck home, the fan was intermittently hitting the radiator shroud. I could see someone had monkeyed with the shroud (put a bunch of cardboard as a spacer between the upper/lower shroud halves. Someone said the motor mounts have likely failed and the engine has sagged. I wasn't sure I believed that. The engine is really solid in its mounts: To remove the old intake I *just* nearly permanently welded to the heads with freshly cured RTV and gasket snot two weeks ago, I literally had to use the arms on my lift and a chain with a bolt attached to the intake to pull it loose. It almost picked the front of the truck off the ground before ....scuuuuuuuuuuup.... I could actually hear the gaskets tearing and it broke loose and the whole truck settled back down. Motor barely moved.   SO, those parts I'm waiting on... The lower radiator mounts/bushings had completely failed. The radiator needs to be insulated from the rad support, and the bushings help the rad stand at the correct height. The plastic "baffle" was also destroyed at some point. Someone had attached the shroud to it incorrectly, overlapping a joint that should have been underlapped, creating another suspect issue potentially causing things to hit the fan. Broken tabs, side is busted off, and it's perma-formed/bent where it was jimmied incorrectly.   The baffle? Unobtainum. Long since discontinued from GM, of course. Aftermarket/capa/chinese? Also unobtanium. In GM's infinite wisdom, it appears there are at least two different variations whether the Blazer is 2 or 4 door, and I can't yet tell if they shared the same part with the S-pickups. Plan B, if I can't find a viable used one, will be to create a bracket to re-assemble the critical joint I need to seal a gap with the shroud. But that will bug me, it won't be...perfect.   The water pump bolts appear to have been installed with...plumber's putty. I guess, sure, if it works...? I've found a few "backyard fixes" like that. Someone's been here before....   If I can't find someone to jam bamboo under my fingernails to fill my free time this week I think I'll install the driver's power window motor and replace the rear door speaker that's inop. I've got a genuine GM "9.5" ohm working replacement. Why GM used a non-standard resistance....nevermind. Of course they did, you can get more sound from a cheap factory amp that way.   And the saga goes on...
