“Driving on highway at about 50 mph when the brakes suddenly slammed on and brought car to a sudden, near stop. The stop was so sudden our seatbelts engaged and we thought we were struck in the rear by another car. Electrical module issues that cause battery to drain while vehicle is turned off have been ongoing since I purchased the car in October, 2021. Car has been in for service related to this problem 6 times and for over 60 days.”

“Upon startup, the back up camera will not display when putting the car in reverse. I could not see if any pedestrians were behind me when backing out of a parking spot. This problem has happened 2 times in the last 2 weeks. So far, the camera resumes working after the car has been turned off and restarted. I called the Mercedes dealership service center and they suggested I make a service appointment to repair the camera system. The car is 3 months old. I will make an appointment to have the car serviced soon.”
