2020 Buick Enclave Electrical System

Infotainment screen will appear black when it should be showing the image from the rear-facing camera, and is showing a red triangle and a circle with a line through it.

The contact owns a 2020 Buick Enclave. The contact stated that on several occasions, the electrical system malfunctioned. The contact stated that the hazard lights inadvertently illuminated, the horn inadvertently honked, and the tire sensor warning light illuminated. The vehicle was taken to the dealer where the failure could not be duplicated; however, the failure recurred. The contact stated that electrical system malfunction again and the vehicle was taken back to the dealer where the vehicle remained. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 28,500.

OnStar system and WiFi intermittently do not work, was told that this is a known issue when radio is being used, no fix. In my case radio was not being used, so this does not apply. Seat/mirror position memory gradually changes over time. Does not recognize that exit function has been turned off. Signal lights randomly flash (without indicator on dash flashing) when car is at idle & mirrors are folded. Tire Pressure monitoring system, not accurate and will notify driver that tires are underpressured by 10lb or more. Dealership reset them and are now fine. Brakes on passenger front randomly grind since day one of ownership Dealership told me that there is an obvious electrical issue, however since no codes are being thrown, they cannot repair it. Best that can be done is to continue to drive it and show up at a dealership when problems are occurring. OnStar diagnostics was able to determine vehicle was not connecting. Dealership indicated they'd let GM know about the issue, but nothing else could be done for what is a relatively new vehicle. Also was told they would not ensure that vehicle was not affected by structural issues because the VIN was not listed
