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?

The last few weeks, about 1 mile down the road after starting the truck, typically on a slow speed smooth highway on ramp, wheels straight, lightly accelerating, the truck will startle the driver with a very loudly pop or crack, which can also can be felt in the steering column. Sounds like its coming from the engine or deep inside the dash somewhere. Has happened now in a similar situation about 5 times. Had a repeat CEL for misfires off and on for over a year when new, but after multiple crankshaft and camshaft position relearn procedures, a TSB to relocate a wiring harness and multiple reprogramming efforts, the CEL hasn't showed up again. Didn't know if the pop/crack could be a misfire and the CEL just isn't activating, or if its something in the dash or steering column. Anyone here experience this, or have any advice?

Which update did they do that finally fixed yours? Glad to know they were finally able to resolve it. I love the truck otherwise, and a ‘22 is nearly 10k more for the same truck vs what I paid.

Yes, they did the supposedly "new" TSB, despite the TSB being dated last year before they did it the first time. Low and behold the CEL is off again like it usually is and things are running smoothly... for now. Just seems like every 2K miles it rears its head again and each time it does, it gets progressively worse.

Truck is a 2021 1500 with the 5.3 and 10 speed. Was purchased new and has been to the dealer 5 times in 12K miles for check engine light issues. 1. First time it flashed for less than a minute and went off without any drivability issues. Dealer scanned and found misfire code on 1 & 6, said no fix from GM yet and sent me on my way. 2. Second time, same light scenario but truck briefly ran rough. Dealer scanned and found misfire code on 1 & 6, did the crankshaft position re-learn. 3. Third time, happened again just like before less than a week later. Dealer said no other fix was available from GM yet, and to just drive it until they notified me. 4. Fourth time, happened again just like before but several months later. Dealer performed a TSB out to relocate one of the harnesses in engine bay away from a heat source. 5. Fifth time, CEL flashed for 60 seconds, went solid for 30, then flashed again, and finally went solid and stayed solid. Truck bucked and surged despite giving it steady throttle, and wouldn't make it up the on-ramp without putting it nearly on the floor. Once on the highway it finally smoothed out, but the light stayed lit. On-Star notified me to "service emissions system within 7 days." Sat at the dealer for almost week. They claim to have checked to see if it was lifters, but performed TSB #21-NA-154 AGAIN, claiming that they have different software available now, from the first time they re-learned the crankshaft position sensor (see Item 2 above). Told me they have three '21s in their shop all for failed lifters right now, and they "hoped" this fixed mine. I argued that #21-NA-154 specifically says its only for check engine light issues WITHOUT drivability issues and I DID have major drivability issues, but they insisted their tech said this would fix mine despite having major drivability issues this time. Anyone else experiencing this many CEL issues? I feel like they're just re-setting the light every 2K miles and sending me on my way without any real fix. Thanks
