GM is looking into camera issues on the T1 SUVs.  Make sure your dealer pulls this up in GM SI if they haven't yet.  There is also info on the engineer the tech/dealer is supposed to call after their

Problem still fixed?  I havent heard anything from my dealer nor found anything online indicating the TSB/eng advisory has a fix.

 

So far the only thing that seems to limit how often we have th problem is waiting for the Chevy boot up logo to disappear after entering vehicle, but before starting.

Been driving it everywhere, no camera problems.  Mine would usually go out after about 15 minutes once the Tahoe was started, either black screen or would freeze on a random scene.   Would take about 15 minutes with the vehicle off to reset.  Chevy tried a software download, next was a video controller, and lastly was the entire head unit.  That is what fixed it.

I just got a 2021 suburban last week, and today this problem started. What was interesting is that I was pairing my phone right before I hit reverse, , so really made me wonder if that was part of the problem But unpairing, turning off phone, waiting 1 hour, etc, still same error screen when the reverse is hit.

 

What has me concerned is the fact that you are still waiting without this functionality, seemingly for months. To me this is a safely issue (what would your insurer think f they knew your backup camera wasn't working?). Your car (and mine) is not functioning as intended, and your Chevy service  left the vehicle with you. As you may or may not know, when a car is in for repair for 30+ days, it qualifies as a lemon, and the dealer is required to replace or buy the vehicle back; at your full cost (minus your usage (at time of first repair visit)).  Alternatively you are entitled to some $$ compensation which can be substantial (if you waive the right to lemon law). The compensation and or buyback includes and rental car expenses, etc. But since you have the vehicle, well, it is perhaps not "in for repair". You may want to contact a lemon law attorney for a quick consultation,.

 

What  I am wondering is can the dealer/service require you to take the non-fully functioning vehicle back when they cannot even repair it and are "waiting to hear from GM"?? I would want an equivalent loaner or rental, and they have it  until they fix it, even though I would prefer to have my own car. If the car is unsafe and most importantly not working as intended, they should fix it, period. 

 

This has me seriously concerned. This vehicle is 8 days old!

Any update? I just got my new Suburban a few weeks back, and a week later, this issue started. Took it to the dealer, found a loose connector which solved the problem - for a day or two. It is back at the dealer, disassembled, and they are dealing with GM engineering on it. For mine, the whole camera system is completely non-functional, all the time.

 

I really find it unacceptable that a 70k vehicle has such a flaw out the door, and the fact that they are struggling to find a fix is unbelievable. As far as your situation goes, the fact that they just gave the vehicle back to you and said, sorry no fix is available right now is a bit surprising and concerning. This is an important functional/safety feature of the vehicle - what would your insurance say if they knew it wasn't working? Also, when a car is in for repair for 30+ days, or in for the same issue 4x, it could qualify as lemon, and that gives you a lot of rights as a consumer; however, you have the vehicle so it probably wouldn't count, even though it is not functioning as intended. . To me it sounds like your dealer just doesn't want to deal with it. I would consider taking it to a different dealer. My dealer doesn't want to give me the vehicle back with out a permanent fix...

No update on my end...I totally agree with you.  I mentioned the safety concerns that you did as well, my dealer reached out to GM - their response was since the backup collision detection still works the camera doesnt represent a safety issue.  The dealer was prepared to start ripping the truck apart to replace things, I did not want that.  I feel it would be better to wait for a real fix and look at it once (nothing ever goes back together the same way.)

 

Waiting for the boot animation before starting the truck seems to have limited our experience with this.  Side effect we are both pretty good at navigating the vehicle without the camera.

yeah I get that not wanting to have the car as a troubleshooter, but I still think it IS a safety issue  - for me I don't think the pedestrian alert is working properly - I tested it - and for certain this car is big and the cameras help prevent damage. Like i said I am sure our insurance would not be thrilled to find out that system was down. 

 

Not sure how I am going to approach it, but we've had the car 28 days on Friday, and 7 of them in the shop, so I probably will be contacting GM consumer affairs at some point next week. I am pretty freaking annoyed that's for certain.

Just an FYI, I finally got it back. Appears to be "working as intended", though for sure time will tell. They as you suspected did take quite a bit of things apart - that was unsettling to see (i needed something out of the car). They needed to replace a camera (not sure which one - think the rear - that was why 1/2 the inside was taken apart). After that, the video worked "intermittently". They traced it to the serial data gateway module (#2.560 - you can buy on Amazon!  https://www.amazon.com/General-Motors-25928052-MODULE-2-560/dp/B00N48MT5E/ref=cm_cr_arp_d_product_top?ie=UTF8), which they replaced. After that it appeared to work consistently. 9 days in for service, owned it for 32 days...

 

For you situation it is a tough call. Not sure service would replace the module based on word off a GM forum - I suspect this isn't simply one issue but possibly multiple and they would have to get it in there to determine the root cause (but they might after communicating with GM, based specifically on your symptoms). As far as wating for GM to issue an official solution, that could be quite some time. There are several hundred TSBs for this line of vehicles already, so it seems they have their hands full. Additionally they are probably reluctant to issue a blanket fix in this situation since it could be  a few (or a number) of different thigs. At best I suspect they would revise the TSB to make it a bit more specific and directed to diagnose the fix. Good luck!

Took the truck in for an oil change / recall repairs, again brought up the camera issue.  Dealer kept the vehicle for the day but was "unable to reproduce".  Service manager claiming that without reproducing the issue and dumping any codes there is nothing that can be done.  This is becoming a very frustrating situation, I would have at least expected some sort of "case" be open with GM so that if a fix or some other troubleshooting measure were to come up that I could be contacted.  Instead I am forced to troll message boards / refresh open TSBs waiting for a fix.

I have a gmc yukon 2021 with less than 6k miles and this camera issue pops up every once in a while. Is there a fix for it? I haven't taken it to the dealer. It always seems to work after I shut it off and come back later.

Nope, no fix here yet.  We actually dropped the car off this week and took a loaner while they continue to troubleshoot/guess what’s wrong.  I am not optimistic.

Truck spent another week in the shop and they replaced one of the mirrors (again).  We had the vehicle back for one day before the issue came back.  Dealership no longer has an available loaner vehicle, so who knows.

 

We are quickly coming up on having the car for a year, this has sort of become a running joke.

So the truck spent another week in the shop and they replaced the "video control module" or something to that effect.  It has been a few weeks since we got the truck back and this is the longest we have gone by far w/out having an issue with the cameras.

 

I am cautiously optimistic that this did the trick.

Middle of November and we have not had a reoccurrence of this issue yet.

I have a 2022 Yukon Denali with 300km, with the same problem.  The back up camera is intermittent, and today got the warning person behind triangle while backing into my garage with no moving objects or people behind.  The camera button to the left of the steering wheel only brings the camera on screen some of the time, and the button on the screen for the camera does nothing when the camera is not coming on.  I haven’t taken it yet.

      Another 6.2L engine failure!

      By MASONV88888888 · Posted

      My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.

      OCI, not when but why?

      By Grumpy Bear · Posted

      Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken.

      Rattle in the rear!

      By MASONV88888888 · Posted

      Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.

      Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
