Curious if anyone else is experiencing this issue--just want to get a sense about how prevalent this is. I have a 2021 Yukon Denali and the rear camera works intermittently (about 30 per cent of the time). Dealer had it all day yesterday but couldn't recreate the problem (of course...). When put in reverse we get the same error screen as above. No rhyme or reason as to why. Will stay like that for a few days then works all the sudden and the cycle continues.... Dealer said there were no error codes and basically they can't do anything. After pressuring them, the tech did finally discover that "PIE0592 GM Engineering is attempting to determine the root cause of the above condition. Engineering has a need to gather information vehicle PRIOR to repair that may exhibit this condition. As a result, this information will be used to "root cause" the customer's concern and develop/validate a field fix". As a result, I am SOL until they can figure this out...
