I searched for this prior to starting .....sorry if there is a thread out there, but I couldn’t find it searching on several key phrases.  All that seems to come up is the auto-start-stop feature on the 1/2 ton vehicles.

 

I’m trying to determine if there is a way to remove the auto-stop feature on my 2020 Chevy HD Duramax?  Fortunately, my sweet little dog was in the truck for less than a minute after the truck miraculously automatically stopped.  I was not informed of this “feature” at the time of purchase.   If one of the moderators can point me to a thread where I can learn more, that’s appreciated as well and you can cancel the post.

 

Thanks in advance for your feedback.

There’s no way to disable it but if you put it in neutral with the parking brake on in won’t shut off

Wow I did not know G.M H.D. diesels had stop/start. Learned something today! Gasser does not have that.

I don't think it has stop/start.

 

I believe what the  OP is referring to is an idle timer that shuts it off. 

 

 

They do have a self cooling feature that, if it's been working hard, MAY restart it and idle for up to about 15 minutes to cool itself. 

 

 

 

From 6.6 Dmax supplement:

 

If the Action Required - Idle Vehicle To Cool Engine DIC message displays, do not turn the engine off.
 

Keep the engine running until the message goes away.
 

Intended Vehicle Use: After a Heavy Towing Event
 

If equipped, when the vehicle is turned off after towing heavy loads, the system may automatically restart the engine. A chime will
sound and DIC messages will display. The engine will automatically turn off after 10– 15 minutes of run time or if enough
cooling has occurred.
 

If the DIC messages display after the vehicle has been stopped and placed in P (Park) with the engine still running, remain in the vehicle with the engine running until these messages no longer display. It may take up to 15 minutes of idling. Do
not park the vehicle in an enclosed area if the messages display.
 

If the system determines that the engine should be restarted and the ignition is turned off, the engine will turn off and then automatically restart. If the engine is restarted,
DIC messages display and chimes will sound. The vehicle cannot be shifted out of P (Park) unless the feature is overridden.
Never leave occupants in the vehicle, and always take the keys and lock the doors if you must leave the vehicle idling. Some local laws
prohibit a vehicle from idling unattended. Always remain with the vehicle until it automatically turns off. This could take up to 15 minutes.

I smell a future law suit coming in on this. Just what the OP described, leave pet in idling vehicle and it shuts off, killing the pet. What if it's a child in the back seat, wtf?

Thanks, Ray.  As redwngr pointed out, It’s actually not a stop/start.  It’s an auto stop only - when you let your truck idle it will shut-off automatically after a specific time period.  

 

Thanks all for your replies.  Just have to plan my trips into the store quickly when my sweet little girl (dog) is riding shotgun on our road trips.

wtf are you leaving a pet and/or child alone in the vehicle for?

Well, it's not on GM when people do it.  That's on the people leaving the pets/kids in the vehicle.

But you leave a truck running expecting it to stay running. No one told the new buyers, had to find  out from experience.

Regardless of leaving it running or not, people aren't supposed to (and in many places, it's against the law and they can get their pets/kids taken away from them and thrown in jail) leave either their pets or their children in their vehicle unattended.

It's in the owners manual.

 

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

 

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 vehicle could turn off sooner if it is parked on a hill, due to lack of available fuel.

 

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

 

 

Some have posted that 'out of park, with the parking brake on' is a work-around.

My truck automatically turns off after 15min. 

 

And yes my dog comes with me to work everyday. I drive from job site to job site as a supervisor. I leave my truck running almost 100% of the time on job sites for specific tasks as well. 

 

Auto shut off is annoying and I wish I could disable it.

Same here, my dog travels to work with me too.  I have a temp alarm that will text me if the cab temp gets too warm for him.  I see no reason why my engine should turn itself off. My previous 6 Duramaxs didnt, and my Ford dosent, so I dont know why this one does. Arg

      Towing In Loose Gravel

      By KARNUT · Posted

      First off use it in the way you’re more comfortable. In working in off road situations most of my life I used 4WD low range very little. In most cases when equipped I used auto 4WD. If I wanted maximum control going up and down very steep terrain  I used low range. Especially if I was driving a diesel. Same with very rutted terrain. In very muddy or snowy conditions I wanted momentum so high range worked well for that. With gravel ramps with limited traction I would try high range first. I would want smooth even increasing speed if I was fighting traction. Low range could give you too much to the wheels breaking traction trying to move.

      Having owned 4wd vehicle since the 1970s I find there are varying opinions on how to use 4wd, every owner is an expert in their minds.  IMO, 4LO is the appropriate gear and what I would use,  You have to feather the gas to avoid spinning tires and the lower the gear the better chance.  But like I said you will find those that think their method is best.  I live near a boat launch.  Yesterday there was a new Ford Maverick pulling out a pontoon boat almost 2x its size, they had no problems and they don't have a LO range.   True story. One winter day not long ago I was coming out of small town post office and there was a F150 4wd parked in front and was stuck foot deep snow ruts. I knew the lady so I asked her to put it in 4wd (wondering why in the middle of a 2-day snow storm she wasn't).  Her reply surprised me, "my husband" (the expert) told me not use that because it uses too much gas. She finally got unstuck spinning in 2wd which likely used more gas than not.

      Your tire pressure issue may just be batteries, you can reset them using tge Ing switch (I think) and the owner's  manual. ChatGTP will b e a faster, better help than Google.

      The thinking is that starting out in a higher gear makes it easier to avoid applying excessive torque when pressing the gas pedal. In a modern 4wd truck with 4 low and a limited slip or locking rear end, I would use 4 low and try to crawl up the ramp. Sometimes if they are too slippery, you have to back up to let the boat have some bouyancy, and then accelerate briskly to get some momentum to help you pull the through the slippery parts.

      I have a Retrax pro that I first had on my 2020 chevy and transferred it to my current GMC.  It stays in the garage most of the time, so hard for me to judge it's long term weather resistance.  It still works perfectly, been very durable.  It doesn't see oil patch usage, but it's not a mall queen.  It keeps most things mostly dry (small leaks) and the security of it is enough to slow someone down but not keep them out for long.  I would buy one again, it works for me.
