NHTSA Complaint #11532759 — 2020 CADILLAC CT5

Cameras not displaying. Backup or surround. Instead, we get a blue screen with message "service camera system). This has happened every other day or so since purchased new in March 2020. In May 2021 it would continually occur (never function correctly). Dealer had it for 2 weeks replacing different components. The radio, the video processing unit, a communication harness, 2 cameras. Finally got it back to us where it would once again work 80% of the time. Then in Feb 2023 it would continually occur again (always blue screen). Dealer had it for 2 1/2 weeks. Replaced again multiple components this time at the direction of GM corporate techs and a field engineer. Replaced coaxs, cameras, video processing unit. Finally got it back to us where it would once again work 80% of the time. Now just 5 months later, it's continually occuring again.
