I have a 2020 sierra. The problem I am having is the camera doesnt work sometimes. this is what it shows. yesterday I started my truck and had no sound switched to Bluetooth, radio, siruis nothing so I pulled over shut it off opened door and restarted radio worked fine. then camera didn't work. Well I have been to the dealership about this issue before they said it has to be doing it when they look at it. So I drove it right up to the dealership. So the serviceman I talked to wasn't there, explained it to the service woman that the other serviceman told me to leave it running so the service tech can do what he needs to do . Well she said she couldn't get it in right away took it outside and shut it off. Well guess what it is working now. Left it there got a loaner. Hopefully it will do it while they have it. Has 1500 miles on it .
