I just had the rear bumper replaced on my 2025 Equinox. Now when I start my car my passenger side blide side mirror illuminates for a couple miles before going off and when I turn my car off bicycle detection system unavailable appears. I took it to the dealership. They said they calibrated it and turned the sensitivity down some. Now I get a message that says lane change alert unavailable along with all the previous issues.

 

I'd be very hesitant about ever going back to that dealer but they should fix the problem they evidently caused. Was your insurance company involved with the bumper replacement? If so, let them know you're having trouble.
