2021 AT4 1500 had this happen at 127miles. I had to disconnect the negative terminal on battery for 2hrs to reset the system, that “fixed it.” Now it’s happened again at 400 miles. This time I waited two days and it hasn’t fixed itself yet so i just disconnected the battery again. Both times I experienced this I used the GMC app to remote start the truck before leaving work. I don’t always use the app. Not sure if it’s related or coincidence.
 

Has anybody found a permanent fix? I’ve read this has been a known issue since 2019. Surely GM has a firmware fix for this by now?

I have a 2021 Silverado LT Z71. Brand new. At 1000 miles, I put the truck into reverse and the camera went out. Never has came back on. Been to the dealer 3 times now and they still do not have a solution. They replaced the camera, no fix. They replaced the whole radio head unit and that fixed it.....for 10 minutes. The tech put it into reverse before I picked it up to show that it was fixed and it just cut out again. Very aggravating that I am paying $400 a month for a vehicle that is having issues. Isn't this the main reason that you buy new vehicles? So there is no hassle? Never buying another GM vehicle. Next truck will be a Ford or a Dodge. I will do a follow up post as soon as I find more information or if there will ever be a final solution to this.

Please open a ticket with Chevrolet Cares, like I did. It’s the only way they’ll move on it. They need an overwhelming amount of tickets. 

They supposedly have one open with GM, but I will open one as well with Chevy Cares. Do you have a link?

I have somewhat found a work around. Please note, this may only work for certain people and that I also have a brand new radio head unit and camera that was installed yesterday, 6/12/2021.

 

I woke up this morning and noticed the camera was indeed working. Got to work and 3 hours later when I went to go pick up lunch, the camera went out again. I reset the radio to factory defaults, clearing the default applications and user settings (there are 3 reset settings in the radio settings menu). I then put the truck into reverse, and the camera was back on.

 

All I did this morning after I noticed the camera was working was connect my iPhone 12 Pro Max to Apple Car play to listen to my music. Not sure if that was what caused it, but I will keep investigating if the camera decides to go out again. With all of that being said, it is most likely just a software bug. I guess working in I.T. pays off a little bit. Maybe I will try just using standard bluetooth instead of CarPlay to see if that still causes it to go out. Or maybe it isn't related at all....IDFK.

Just an update, it went out again yesterday afternoon when I needed it to back up to my boat of course. It came back on within 15 minutes of me being outside of the truck and it just running. After I connected the boat and went to pull away, it was working. It has worked all day ever since I got in the truck this morning. I am talking with the dealer on Monday so they can take these details and let their engineers know. So I guess it's good that I am getting it to work here and there, hopefully they can figure this out for us.

Hey @Josh Nelsonthanks for your diligent work in getting the issue documented and reported. It’s so frustrating. Ours went out as we were trying to hook up our trailer. Finally just used FaceTime. Hopefully they’ll fix it soon.

Hello all,

I own a 2021 GMC Sierra 1500 AT4 and the camera intermittently fritzes on average about once every 4-8 weeks.  Every now and then it has a difficult time starting again on average about once every 4-8 weeks.  Regarding the camera it would show the same not working symbols shared above.  The starting issue would last about 5 seconds and stop upon which restarting would be normal.  I've went into the dealer to have it looked at and they reprogramed and updated the software/firmware and it was good for about 2 months and then it started again.

 

When the camera fritzes it usually comes back on the next restart or after parking it for the day and operating the following day.  I will start a more rigorous data compilation and hopefully videos of the starting and camera issues for the next shop visit.  I will share findings as they come about.

 

Additional efforts to research the camera issue led to possible causes via faulty wiring, a bad fuse, or a software glitch.  I've yet to dig further into each of these.

 

Cheers to all,

Wiggy

Same problem as everyone else, worked then it doesn't.  What makes mine unique (but not special) the truck literally roll off the trailer on Thursday with 2 miles on it, and I drove it home on Friday with 15 miles after the Dealer prep. 

 

I bought and traded in my 2021 1500 LTZ with every piece of tech option you can get on it back in May with 45 miles on it.  Not a single problem. 

 

With less than 5000 miles I traded it in for a 2022 3500HD High Country minus the HUD and live rear view mirror.  (Chip shortage?) And now I'm an unfortunate member of this problem.  After trying to "reset" the problem back to working to no advil, I went an completed my profile setup, and configured the dash.  Don't know if it helps troubleshoot the problem, but I also transfered my ATT Internet and Onstar over to the new truck when I picked it up at the dealer.

 

This morning.  Works like a champ.  Ran errands - backed up to park, used the cameras to squeeze through the concreate curbs at the bank, etc.  

 

Update: More errands, used the cameras all day, the problem hasn't resurface.

      Tire psi

      By jgaudet99 · Posted

      Yes that's right, it's the upgrade that includes the overload spring and all that stuff.   Someday when I'm empty and going by a scale I'm going to stop in and get some weight readings.   Exactly  you should have the ability to change individual settings, in in Canada so I'm driving with kph but then I'm stuck with kpa when I want psi lol

      You must have that upgraded gvw package which is only available or at least was in 2025 with the diesel engine for the 3/4 ton and that gave the truck physically the larger 12.0 ring gear rear diff and the 3500 rear spring pack. There is a difference in what the diff housing looks like externally as one tell tale and also your truck should have the upper overload spring pack and the frame pads that the pack goes up against.    The pressure the tpms system kicks the alarm in on a stock setting truck, that is a good question and was just from what I recall but I doubt I made any notes on it as I knew for the rear that it was not at all what I was after regardless either. Being that you have a diesel and if running on stock tires the minimum pressure on an empty truck seems to be around 50 psi from hearing of those that have weighted the front axle but the rear axle is very similar in weight to a gas truck and again a near empty truck on the rear could go down to 35 pounds at minimum. However the weigh scale is the proper way to know for sure as a guide.    As to changing the readings on the dash from metric to the US measuring system, oh yes that is done easily but what I was attempting to explain was that I can't pick and choose items I want to have in US and those I still want in the metric system at the same time as its either all or none. For example lets say you drove into Canada and switched your dash over to metric so your speedometer read in km an hour, well then your reading kilopascals on your tpms readout and your wife looks over and says what the hell is that saying in the tpms screen and you say "darned if I know, I think its Chinese" !

      This is partly why I decided to have switched over to Amsoil SS as a way of hopefully preventing the buildup of the sludge/carbon on the pistons and clogging of the oil control rings and the carbon that would cause the compression rings to stick in their grooves as well as stay cleaner up top of the heads in the valve train in the first place, an oil that has tested better by third party testing over typical shelf oil and also doing my best to run relatively short OCI. However in saying that I don't think there is any way to easily prove the oil I was using prior allowed for a buildup at the OCI I was doing, nor in the other direction to make claims the Amsoil is keeping everything clean either. There really isn't a window into the engine is there to know anything for certain even if oil samples were taken for example that showed still healthy oil being dropped out of the oil pan other than engine tear downs that extensive and expensive testing of oils does to actually visually see what is really going on inside the engine. I wish there was some easy method of seeing what is going on but I don't happen to be aware of that if there is.

      My truck is a ¾ ton but my placard also says 80 for the rear tires, I think I might have the upgraded suspension to the 3500 series maybe.   I put my air down to 60 and the light was still on, and there was no way I was putting over 60 psi in the rear empty and not towing because I knew the actual number Toyo gave me and I didn't wanna ruin the center of my tires!   And you actually can change it in the settings from metric or is and it will show kph or mph then when you go into your tire settings it will be either psi or kpa, but it would be nice to just change it directly on the tire psi page

      Common Sense Assembly   Your driveline is forgiving of the occasional mistake. It will even often forgive the random serious blunder. But it will not forgive a continuous bad habit.      What? Not everything needs to be a five thousand word essay.
