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

2021 2500HD LTZ

 

Same thing.  

64139606041__DBCC7507-057D-4A21-A6D2-5D82234CBB75.fullsizerender.jpeg

Same happened to me on my way to lunch from work today.  On way back to work, still wasn't functioning.

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.

    • Declaring victory would upset the demons that possess this Blazer, so I won't. But I did make progress today--after it put up a fight. Always a fight.   I had the day off so I spent the morning cleaning up the shop and I thought I'd get ahead of things by filling the cooling system in prep for the final part I needed to arrive: the driver's side knock sensor. Glug, glug, glug....and then the unmistakable sound of liquid hitting the shop floor. It induces the same chagrin when the sonar and targeting laser temporarily malfunction during a late night bladder evacuation over the toilet with the bathroom light off. D'OH!!! That made a mess...   Oh, hey, that knock sensor I removed? It threads into a wet port. Who knew?! Learn something new every day. Put a pin in that chore, I'll fill it the rest of the way later.   The knock sensor arrived at about 1pm. I threaded it in, connected the wire, filled up the coolant, checked for leaks, and... drumroll.... fingers crossed for a perfect start, excellent timing, model fuel trims, and ...no squeaks... Here goes.....   No, it didn't start. At all. I cranked it a few times and it wasn't sounding good. Furthermore, I heard leaking again. Jesus H Tapdancing Christ, stop leaking all over the dang floor. This time I had accidentally overfilled the coolant reservoir and the churn of the water pump via cranking caused a bit to burp out. Ok, just, breathe... Put the flamethrower down. Dang thing wouldn't burn anyway, leaks too much...   Did you know the rotation of a round crank sensor in a round hole, matters? I do now. Took me about half hour to retrace steps and realize what I had done. Then it started right up.   No squeaks. The squeak was the old balancer.   Once it entered closed loop, fuel trims are dead on, hovering right around zero at idle. No more -30%. I'll credit the injector rebuild on that one.   Timing? I think there's an OBD 1.5 translation error with my Actron scanner. It's anywhere from -20 to -30 at idle, sometimes as high as -40 cruising. Sorry, the engine just isn't running that smoothly at -40 degrees ignition advance. It's just not. It's smooth all through the rev range and has decent power. I'm going to have to trust the seat of my pants on this one.   The new exhaust is very quiet. The old catalytic converter? Not melted, but definitely not healthy. Rains glitter when you turn it on its end...all the precious metal is flaking out. Once the new exhaust system burned in/smoked off a bit, the engine's exhaust smell is normal again. Not that I'd recommend going around huffing car exhaust, but, you know what I mean?   One problem to correct. The new exhaust has the opposite problem of the old spliced up exhaust. It wants to hit the floor where the old one wanted to rest on the cross member. Happy medium, please? Still noodling on that one, need to look at how I can adjust some hangers.   I don't know what's next. On one hand I want to run away from this thing as far and as fast as I can -- there have been a lot of NOT fun moments. On the other, now that it kinda drives nice, maybe drive it around for a little bit?   Shhh... it's not currently dripping oil all over the floor. I can see just a little wet at the bottom of the timing cover where it meets the oil pan seal. It's not dripping multiple drops with every ignition cycle, in fact, after some driving this evening it has yet to even form a drop that could drip off yet. But the weekend is young... I fully expect this could turn into Exxon Valdez by Sunday. Because this Blazer hates me. LOL.      
    • About that:   Once upon a time in a land far far away lived a car company that was shy about taking your money and wanted to be sure that they gave you more that you asked for so that you'd come back. No really, not a fairytale. 😱   But after the field got thinned out enough to limit the competition it seemed good enough to give you only what you asked for. Fair enough I say but in such a market you have to give something the others are not or they go to the one who does. Gimmicks or glitz. Oh, fins and chrome. Yea, shinny crow like cars. Yum.    Field narrows a bit more and 'brand loyalty' becomes a thing and the minute it does they start thinking to themselves, "Could we make more money if we gave them less than they expect and they will hang in there for brand and comfort with the known?" They gave it a try and da*n, it worked!!    Well, what if we teach them, groom them into believing that less is "Normal" and cut some more corners. Will that work? Oh heck yea!    🤔 I wonder, can we give then WAY less than they expect and make them mad enough to spit nails and STILL get them to pay up? Sure, if we get everyone else to do the same so that the choice is less or nothing at all. How would be do that? Platform sharing.  What a concept, right?  Steal like there is no tomorrow and it's legal too!    Truth is no one is going to give up driving, not for very long. The Gen Z crowd is fine with it and will be as long as someone not Gen Z will haul them around. At some point we all die.    Economic voting only works if you cast a NO vote now and again and enough of them to get dumb and dumber to wise up. Well, that's how I was taught anyway. And it should have worked. Would have worked. But the Bail out!!   Look, you have another choice if  you take that bag off your head. If the dumb it down to some predetermined expectation of how John Q Public will use it the, that is under design it to failure they you use it to a lower stress mode. D'ho!    A 1950 Royal Enfield Bullet 500 will go anywhere a Suzuki Hayabusa will and for just as long. But you will have to treat it for what it is and not for what you wish it was. 
    • Maybe I was just too unlucky, but I had nothing but bad luck with Bridgestones. Out of 3 sets, they all started losing a lot of air when they got down to about 1/2 tread life, and at that point also wet traction suffered more than it should have. Also, the only tire I ever had in my 60 years of driving that had a side wall blow out was a Bridgestone.   I'm currently running Goodyear Wrangler Workhorse AT and am very happy with them.   
    • maybe when the trip is over, check all the other joints in the front end, like all the ball joints, tie rods, pitman & idler arms, etc...
    • Thks, and actually it was my bad, because here in this post there is someone showing the correct wire position as well. My bad... But thank you a lot with the help as well. I was able to find and buy a 10 channel VPM that came from a sister silverado of mine. The same year, same mode, same trim, same everything. 2022 Silverado 1500 LTD LTZ (pre-refresh). I also found to buy just the bottom mirror part that has the cameras, so way cheap than the full mirror. + a used front camera. I did test everything together, cameras, cables and the VPM.... everything worked EXCEPT my original Bed camera and the backup grid lines. I think the reason is because now I need to do the VPM reprogram. I sent a msg White Automotive & Media Service to confirm that it is the problem and that they can do it service for me case.   Once I get it 100% done I will post here result....
