2021 Sierra 1500 Side View Camera Failure AGAIN

[tjonesdfw]

2021 Sierra Denali with 42K miles has been experiencing repeated intermittent failure of the driver side view camera.  When utilizing the surround view camera system, the driver side mirror camera is either blacked out, or flickers from image to black.  Have video documented it multiple times for dealership.  Truck has previously received at least 3 replacement camera modules, a new tailgate camera, and had the rear window leak TSB completed along with another camera module right before factory warranty expiration, as dealer claimed the window was allowing water to leak on the camera system behind the rear seat and had taken out another camera module.  With the same problem rearing its head again, has anyone had any luck with a permanent fix to this camera issue vs repeatedly throwing parts at the truck?  Wondering if the rear window could already be leaking again and causing the camera module to fail?  Unfortunately this truck has had electrical gremlins starting under 100 miles to present; multiple CELs for misfire codes, camera failures, camera module failures, park assist failures, stereo failure, etc.
