Example complaints

Transmission and drivetrain: “Car randomly goes into neutral despite being in D drive mode. Often at stop light, after the light turns green, the car revs up but is not in gear despite in 'D' drive. I have to shift to park or turn car off then on to get it to go again. This has happens multiple times since new. This is very random and distressing when it happens. Car has been evaluated multiple times at the dealership. There are no trouble codes thrown. The car otherwise works and has no other problem. The technician (off the record) told me there is a known issue when he contacted Germany. …”

Other or unknown: “I was driving on the highway, with no other cars near me and my panoramic sunroof exploded. It made a very loud gunshot like sound and I felt shards of glass fall on my head while driving. I had 2 other passengers In the car. One in the passenger set and one in the rear passenger side seat. They both had glass hit them in the face on head and go inside their clothes. I was extremely startled thinking that someone had shot at us or something and had to quickly take a highway exit to pull over and see what happened. …”

NHTSA complaint #11622207, filed 2024-10

Electrical system: “Car stops accelerating and shifts into neutral without warning I nearly got hit from behind. I have consulted several other Mercedes vehicle owners and all had the same issue. Two of the other owners stated that this happened on the interstate and was very lucky they were not involved in a collision. Both vehicles were GLC 300. Mercedes does not seem to have an answer to the issue and all previous owners traded vehicles for fear of dying.”
