“New car was purchased from Rocklin Mercedes in California. Soon after the rear back up camera kept opening and closing when the car was in drive and at random times. The was then taken into Autobahn Motors in Belmont California to have the problem checked. I was told Mercedes was working on a software fix at which time the service tech never wrote up the problem. In 2025 the car again was taken into Mercedes for service at which time I brought up the same issue and was told most newer cars have this problem and there is NO fix, even the loaner they gave me had the same problem.”Owner report · Back Over Prevention · Sep 2024
