Side Mirror Camera Intermittent Failure

Several times the driver side mirror camera has not worked, and the surround view displays a black block all the way down the left side of the truck.  When the camera does work, it flickers between an image and a black block on that side.  Has anyone experienced this and know what the fix was? 

 

I've already had the camera module replaced twice, and a tailgate camera replaced once for the black screen and red exclamation point when putting it in reverse, and now this.  Between the parking sensors randomly disabling themselves and being unable to toggle on or off via the switch, repeat camera issues, and repeat check engine lights for misfires with 5 attempted repairs, it's sure frustrating.  Are all these new trucks just destined to have electrical gremlins now?

Gremlins comment, pretty much.

GM has real bad EMC/EMI issues these days and it's hard to say if its related to that or its bad signal to noise ratio for the camera feeds in general.

Of course software on the modules could also do this and drop out but likely you have a deeper issue than just the camera module itself.

Might need to replace/reflash the main ECU that takes all those camera feeds together or play around with grounding the coax camera lines to the chassis at the ECU itself.

Not sure where they go to or what the ECU is called but the same methodology applies to all the new hot garbage GM pumps out on any vehicle architecture.

the biggest problem with all manufacturers is they keep adding more computers but they don't update the software to diagnose the systems. i feel sorry for some of the techs today because they can't do their job without the right equipment. so you bring your vehicle in when it is still under warranty and first thing is to fire the parts cannon and hope for the best. or they have to totally disassemble your vehicle in hope of finding a problem. your mirror problem is probably a connection problem but in order to find the problem your rear seat has to be removed or your door has to be taken apart. when you are out of warranty you are sol. now a days you have to know how to use an ocilliscope

Can someone tell me the best way to take the bottom housing of the mirror off so I can cleans d seal the coax connection. I notice that it blacks out much more after I’ve gotten a lot of dust and water I side the cover. It seems to just be the driver side and clears up with a clean dry truck.

I have had the same issues with my 2019 AT4. My cameras tend to go out when it rains or I take the truck through the car wash. It seems like a lose connection somewhere.

Has anyone solved this issue? Just bought my AT4 this weekend. It was fine when I bought it and for the first few hours road-tripping home, drive through some heavy rain, and my drivers side camera looks just like it does in that picture up there. Came back on yesterday, and today it’s doing the same thing again.

Truck went back to dealer last week for the same problem again.  Dealer said they were replacing the left, right and rear camera harnesses but GM only approved the rear harness for replacement.  They claimed to find a short in the rear camera harness coax and the rear camera (that’s been previously replaced already) had an internal short in it.  Not sure how that makes the driver side camera go black or flicker but this was their solution.  They dropped the spare assembly and disassembled the whole tailgate to fix.  Time will tell if it rears its head again.  This is repair number 6 or 7 to the crappy HD surround vision system.

I bought my 2022 Silverado 1500 brand new in summer of 2022 and this issue began happening almost right away. It's been to the dealer over five times. One visit I had to wait several months for a wiring harness to come in that was on galactic backorder. This didn't even fix the issue when it did finally arrive. Currently today my dealer is STILL working with GM to diagnose the issue. Who knows when, or if, it'll ever be fixed. Anyone experiencing this issue, good-freaking-luck!

To me its clear GM has an issue with reliable electrical systems if it takes this many repairs and they keep throwing different parts at the system.  Since our last camera system repair we haven't had a camera failure yet, but the parking sensors have failed for the fifth time and will be going back for repairs at the next service visit.

Latest update… the driver side camera failed again.  Either flickering black or solid black. This is will be the 7th or 8th time to take it to the dealer for the same damn camera issue.  No faith GM even knows how to fix the cameras in these trucks.

One of these days I want to remove the rear seat and get to the VPM (video processing module), Im fairly certain simply grounding the coax shields for each cable to the VPM housing and then also to the body/frame would solve all these issues.

They AC couple the grounds for these camera lines so that DC current doesnt use them as a sink path if the main ECU ground fails open and it causes all kinds of EMC problems like camera drop outs and glitches.

      I knew when I bought my truck that it had off road hill decent or craw control or whatever they call it and rolled my eyes at that but it gets throw on with other options my truck has, I just never had a heads up if the highway speed regular cruise setting had anything to do with the brakes and that took me by surprise. If you've ever been to the top of Pikes Peak and watched those ahead of you on the way down with their brake lights on constantly, one can guess they are probably not gearing down or not enough anyway if their vehicle will allow and a good reason their is a brake check spot part way down where they use an infra red heat gun to check how hot ones brakes are front and rear.    Your right that once one gets out of the front range by Denver and I've not been on that stretch of 285 between Denver and Fairplay myself but I know its high and Fairplay at 10000 feet, Buena Vista at 8000, it drops a bit from there but then your going back up and over the 11000 pass and Durango is at 6500 . So yes your definitely right that 6500 and a lot higher is the theme of going anywhere out in that direction from Denver but hey, the down hill sections give fantastic fuel mileage !.    I don't even look at the fuel pumps for what premium costs here, since I live on a farm and up to this point get fuel delivered I am rarely in front of a fuel pump and when I am, I am often using card lock bulk fuel stations so it tells me what the price is AFTER I buy the fuel. Looking up on gas buddy and converting to US gallons but in Canadian dollars, regular on average of the prices listed was around 5.95 and premium is around 7.00 . That was one reason I did not go for the 6.2 half ton aside from its lack of carrying/towing if one was going by the rule of using premium fuel and until recently one could only buy regular farm gas if playing the few cents off game for farm dyed fuel for a "farm licensed pickup". But yes I hear you on the fuel price difference and like the diesel theme with it often being more expensive then gas it doesn't have quite the charm to it either as it once did although right now here for some reason the price of diesel has come down more so its now inline with the price of regular gas.

      Missing thrust bearing? And oil selection

      By KARNUT · Posted

      I agree with this assessment. As you know I’m testing longevity with vehicles for the first time. I have a few vehicles I passed to kids and grandkids. We’re all past 100K miles some approaching 170K. I’m the only one doing 5k oil changes. The rest whatever the minder says. I’m the only one doing frequent transmission service. My odyssey the trip vehicle at 200K will be finished as a trip vehicle. I recently changed to high mileage oil, Valvoline. I can’t get past the fact that all manufacturers want to claim long service life. I just don’t make sense that they would go with low weight oil for mileage. While sacrificing longevity.

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      There's absolutely a mountain of profit in catering to the "I do my own research" crowd, people who are certain they know better. And I don't mean there isn't data to support that 0w40 produces less wear product than 0w20 in an engine like the 3.0 Duramax, that only feeds them the assurance they need. Again, my whole thing with oil selection is, sure, 0w40 or 0w30 produces less wear product. Are we talking the difference between the engine lasting only 100k versus 200k? Or are we talking more like, if the engine will already go 350k on a good 0w20 regimen recommended by the OE, is using 0w40 going to get us to 355k, assuming we can even get the rest of the truck to last that long, meanwhile sacrificing the first 5y, 100k in powertrain warranty. The answer isn't easy, there are tradeoffs.   I willfully use 0w20 Dexos D for this reason, knowing that a 0w40 will produce slightly less wear. I don't believe the delta in wear product is meaningful over the lifetime of the engine, and I place much more importance on driving style and overall feeding and care of the engine as a whole. It's the mentality that someone can abstain from alcohol their whole life which is an amazing boost to health by itself, theoretically. But if they're sedentary, that lifestyle choice will most likely kill them young despite their other, concerted efforts. Maybe someone doesn't drink AND they are the perfect picture of health and activity AND they use 0w40 AND they treat their engine perfectly. If living until 130 years is the goal, sure, do that. But it's going to be a really old truck falling apart around a good engine for that last 30 years, without a doubt.   I watched Demonworks' other video on the 100k+ 3.0 Duramax that had dealer 0w20 changes on what appears to be OLM-prescribed intervals (8-10k).   The QR codes are still present and readable on the main bearings. That's how little wear it has.   That's not proof that anyone else should stick to 0w20, but it's confirmation, for me, that 0w20 is perfectly acceptable to use in these engines.

      oh ya that's good to know - I would rather use a gear than the brakes down a long hill.  I would not let cruise control take over on snow or towing a trailer for sure on hills anyway.     The other thing about the CO trip was that was all done above 6K feet for the most part, so that has to use more gas as the motor is down a good amount of power up there.   If I drove my 2016 Camaro with a very similar V8 to this 6.6 it would probably get about 23-24 on the fast run up to NE.  But the premium fuel premium is steep here in CO, so it would still only save about $40 in overall costs for the round-trip.  And you sure can't carry much gear in a convertible camaro!
