“When going into Reverse the passenger side mirror angles down to see curbs. When putting back into Drive it should be going back up to normal angle, but 20% of the time it does not go back up. If you're driving in the dark you may not know it's reverted back up and get into a car accident. Dealership said there are no issues and a technician stated it goes back up at +9 mph. I've gone over 30 mph driving on public street only to realize it late. I am hoping this gets publicity before an accident occurs due to a defective safety-comfort feature.”Owner report · Visibility/Wiper · Nov 2025

“While driving at 60mph my panoramic sunroof completely shattered. Nothing at all hit the sunroof to cause it to shatter. If my sunshade cover had not been on, the glass would have fallen on me while operating my vehicle. This is not only dangerous but unacceptable. It was also a distraction that could have caused an accident. Mercedes did not make me aware of the class action lawsuit they have with the panoramic sunroofs, and I feel that was neglectful on their part. Upon inspection from a service advisor at a Mercedes Benz dealership, they told me something must have hit it (nothing hit it) and want to charge me $4,000 to fix it.”Owner report · Structure,Unknown Or Other · May 2025

“Filing complaint on behalf of my sister. She was driving on empty side street around 25mph and the car comes to an abrupt stop. Apparently part of the collision avoidance system, yet nothing in road, on road or in sight. If there was anyone behind her, they would have slammed into the rear end of her car.”Owner report · Forward Collision Avoidance · Apr 2024
“On 2/17/24 the vehicle was parked in front of my house. There is a slight grade. The vehicle had been parked for approximately 1 hour when my neighbor called me to tell me that the vehicle had rolled down the hill and into his storage building. The vehicle rolled on its own. I have video evidence that no one was in or around the car at the time of this occurrence. I also, have 2 eyewitnesses who can corroborate this story. Due to safety concerns, I immediately returned the vehicle to Mercedes. I have .MOV files and pictures JPEG that will not upload for some reason.”Owner report · Power Train,Service Brakes · Feb 2024
