Terrible Feature - Truck Shuts Off On It's Own?!?!

Well.  I'm here because I too need a way to disable this "feature".  I traded in my 2018 Denali for the 2020 AT4 2500 Duramax.  I use these trucks to haul trained military working dogs to their final locations.  The trailers we transport these dogs in rely on vehicles running to power airflow controls (heat/bringing in fresh air), lighting and water pump.  Today, after thirty minutes of being in a meeting I walk out and my truck is off -- and the dogs have no heat (it's 22 degrees out).  I instantly freak out thinking I made the mistake of shutting the truck off.  (Why would I ever assume the truck turns off on it's own?). So I restart the truck, we begin the process of unloading dogs, as we are the truck shuts off again.  Our trucks (companies) sometimes run for hours - this is just nature of the business.  The fact we can not disable this feature is an issue.  I have already spoken with the dealership to return the vehicle as I have less than 100 miles on it.  The truck does not work for me because of this one simple "feature". Yes, I'm sure there are work arounds as some of you posted in here -- "restart the truck when it goes off".  This does not scale.  I'm in disbelief that they did not provide an option to turn this off..... so there is no fix ... this is confirmed... as they are taking my truck back because of it.

I would have a generator on the trailer.

Its a safety feature so you dont pull up in your garage and kill yourself.    Leave the key in the car and it wont quit.

Maybe people should read what they're commenting on before posting useless AND incorrect info.  People shouldn't "guess" at answers to technical questions or questions to which they don't have a clue

This makes a lot of sense in many ways because the generator would then always be where the power is needed and probably a lot more efficient for the job as well.

Try leaving it in neutral and setting the parking brake?

 

Edit: I replied with this before I saw that it was mentioned a few times. Also didn’t realize this post had 137 replies.

I work for a professional emergency vehicle upfitter. Over 40 years experience doing police equipment installs. I just finished a 2020 Silverado 1500 SSV. It still has an ignition key. Answers an earlier question about the police package vehicles shutting off if left idling for extended period of time.  Maybe the Deputy Fire Chief's department may need to look at replacing the 2019 GMC's with a 2020 Chevy 1500 police package.

Researched also and stumbled on this thread 

 

it’s 15 min if key is in vehicle, up to one hour if the key outside vehicle and the doors locked. 
 

pop the hood I believe will disable it. The ecm will think it’s in service and stay running. Still looking for a ecm setting work around.

I have been buying (2) 1500 silverado's every year for the past 11 years with the awsome 6.2L. They are used as business trucks for  work in the field in remote locations. The people that are using these trucks are using them as mobile offices. This feature of shutting off when ever it wants is for the birds. I realize that this was installed as a safety feature but it is a big pain in the butt! If their are that many dumb people out there that they can't tell when their vehicle is running or not, maybe the push button is to advanced for them and we need to return to a key system. I hate that I am being forced to look for other options for trucks and as of this morning a Dodge 1500 Limited got the nod. Im going to miss the awsome trucks chevrolet makes but as the cold is coming and I can't have people in freezing conditions with trucks that dictate to them when they will work! If your looking for a daily commuter and not a work truck look at Chevrolet!!! Such a shame!!!

Truck is a 2019 Sierra AT4 and I'm really surprised to find it shuts itself off on it's own after idling for somewhere around 10 - 15 minutes.  I'll admit I have not had time to read the manual yet but this was not an "option or setting" in any of the settings menus.

 

Really sucks for me as I'll leave the truck idling for several hours at a time if headlights are needed to provide jobsite lighting.  I'll be elbow deep in "work" and the damn thing just goes off.  I need to go over to truck and restart every 10 - 15 minutes which is a pain in the ass.  I won't even get into how bad it is when I have to sleep in the truck while on a remote jobsite.  It gets cold very quickly when it shuts off....

I guess you should have researched the truck better first.

2020 OM:

 

If the vehicle is left parked and running with the RKE transmitter inside the vehicle, it will continue to run for up to an hour.


The timer will reset if the vehicle is taken out of P (Park) while it is running.

Were you able to ever figure this out?

I think my truck is broken. The auto-off feature has not happened since the first week I bought my truck, back in July 2020.

 

I did have a brake ECM light, drove it in and they said they just had to flash it. Never shut off again after that. 
 

should I complain?

 

kidding, of course I’m not going to complain! It was annoying the first week.

WAMS - In addition to programming it so that the truck doesn’t automatically turn off while idling in park, can you also make it so that accessory mode stays on indefinitely (or lengthen the timer)? I’m talking about the mode when you press the start button without your foot on the brake pedal).

Is there a full list of changes that can be made?

 

ETA.... I guess I should have asked is there a list of how long the timer is change for? As in hrs or eliminated?

The maximum value for fob in/out of vehicle time is 99999.0 Seconds... should be enough right? ?

      Gasser Subforum Has Been Quiet - - So, Regenerative Braking and Using L10

      By jake111 · Posted

      Thanks newdude!  By the time manual selection is needed, I'm probably too much of a control-freak to depend on the transmission sensing braking to activate automatic downshifting.  I would be anticipating the situation and already be manually downshifting.   This truck replaced a 2004.5 LLY diesel with the Allison 5-speed.  Putting it in T/H made noticeable differences (when the torque converter locked, upshift points, downshift behavior).  On this 2024 gasser with the 10L1000 I haven't been able to detect much, if any, difference.  Ok, I can never tell now when the torque converter locks up.  But I also don't notice differences in shifting.  For downhills, I've probably already manually downshifted by then anyway.  Since it's also more awkward (than the 2004.5) to engage/disengage I don't even bother.  Or maybe it doesn't really matter with just a 3k lb. camper in the bed?   Thanks also for the list of reasons the charging system might select various voltages.  However, what I am seeing doesn't fall into any of those categories.  It very definitely, and very consistently, rises after coasting/braking.  Maybe not immediately, but not very long after coasting/braking.  Very consistently drops voltage when no longer coasting/braking.  It might also be interacting with the camper battery charging (I might disconnect the camper and see if it changes the charging behavior).  I also need to recheck turning on headlights for when I want to force it to charge the camper.   Another JR, in June I converted the camper to LiFePO4.  Since it's not a good idea to try to charge lithiums directly using truck, I installed a Victron Orion XS DC-DC charger (which BTW is AMAZING!!).  Being cheap, I only had to buy that one item (besides the battery, of course) to do the conversion.  The camper OEM 120v battery charger (only 19 years old and works perfectly) and the truck feed the input to the DC-DC charger (not at the same time).  But I didn't want the camper charger feeding back to the truck so I kept the old separator.  I considered replacing the separator with a 30amp diode but that means more work and might add another 1/2 volt drop.  One thing that surprised me was the voltage drop over the long 10awg wire run, so I can only charge smoothly at 8 amps (because the DC-DC charger is completely configurable).  Another reason I don't want an added voltage drop with the diode.  I might also be a little lazy but all this work is being done under the sink with a small cabinet opening.

      cam upgrade in CA

      apparently CA smog is (or at least was)  checking that the vehicle is using the oem and/or a ca smog approved tune, so I expect you'll fail inspection doing it.

      yes, leaking exhaust will mess up o2 sensor readings, which in turn messes up fuel trims.

      286,740 Mile Services   8/6/2026   New AC Compressor. Refrigerant oil and dye, evacuate and charge system.  New exhaust system from cat back.  New Iridium plugs plus replace #3 coil Repair/rewire headlamp wiring (passenger side) and replace all forward bulbs. Polish lenses of both assemblies.  Pull rear rotors, clean and adjust parking assembly. Inspect, clean and grease front calipers. Check pads and shoes.  4 wheel power bleed of brake system. Dot 4 Reset idle speed 50 rpm higher New Serpentine belt.    Will need new pads in the rear in about 5K more miles.    Tax Title and License out the door just short of a grand.    AC clutch had bitten the dust. 1 year warranty on the pick and save replacement. Thing will make a Polar Bear cry Uncle.  He spent quite some time on the wiring. It was in the harness and he does nothing half. I got off cheap. I have considerable more light down the road. Sylvania Silver Star replacements.  Gas seal between the porcelain and shell of plug #3 was blown, cooked the coil. That was the cold miss.  Love the new exhaust. I can sneak into the neighborhood again.  Nice to have a working parking brake again. Belle Tire never got it done. That was disappointing.    This was one of her bigger bills and still way cheaper than a payment even given the oil consumption. This thing cost me under a hundred a month in repairs and normal routine costs. What is my incentive to replace it? 🤔
