Invisible Trailer Camera

[Certpilot]

I bought the trailer camera when I purchased the truck. The camera is installed on a 21 ft enclosed snowmobile trailer. It worked great for the first winter with one exception, every time I pulled up the trailer profile the system would not recognize the electric trailer brakes. It did however control the brakes. In April of 2021 when the season ended I took it to the dealer and they said it just needed to be reflashed in order to recognize the brakes. Well I still have the error message about the brakes and now with every key cycle the camera requires re-calibration. It has been to the dealer numerous times, the supplier worked on it twice, and GM engineering has worked on two or three times now. Even though the system states the calibration was successful and the camera works, once the key has been cycled off and then back on, the camera requires calibration again. I need help.

I have same issue with the electric brakes notice on my 2020 Silverado 1500 if/when my Trailering App works (get a blank screen a lot) and I also bought the trailer camera. The electric brakes notification is on my list for dealership service, but your side effect with trailer camera has me concerned that it will also happen to me. I'll post after my repair. Good luck to you.
