What owners report
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.
The contact owns a 2023 Mercedes-Benz C300. The contact stated that on occasion while driving at various speeds, the vehicle unexpectedly stopped without the brake pedal being depressed. There were no warning lights illuminated. The vehicle was diagnosed twice by the local dealer, and the contact was advised that the Forward Collision Avoidance sensors needed to be recalibrated; however, the failure persisted. The vehicle was taken back to the same dealer where the vehicle was inspected, and the contact was advised that further diagnostic tests were required to determine the cause of the failure. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate
My panoramic sunroof spontaneously exploded while driving down the highway, no external impact was made. The glass exploded from the inside out. It made a loud boom, it startled me on the highway resulted me to swerving on the road, which would have put me and other drivers at risk. There's plenty other MB drivers reported similar issues that stated. MB has also settled a class action lawsuit regarding such manner. UNKNOWN There were no warning signs prior to the event. The event spontaneous and sudden.
On 4 different occasions car brake assist activated causing car to come to an immediate stop and jerk. At stop light as I started to accelerate a left turn car came to an immediate stop almost causing the car behind hit rear end. Brake assist light activated. This happened twice. And twice when in reverse backing out of a parking space and backing into driveway. Dealership notified look at my car and stated they did not see anything wrong. 4th incident happened within 30 minutes after leaving Wilmington Mercedes Benz.
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.
