Example complaints

Other or unknown: “Sunroof exploded and shattered. I heard it while driving and held on tightly to the steering wheel before I realized what it was.

NHTSA complaint #11721035, filed 2026-02

Electrical system: “- My transmission is malfunctioning. It is available for inspection. - My car is not allowing me to shift from reverse to drive. When I try to put it in drive, it gets stuck in neutral. My safety is at risk as I was trying to do a quick 3-point turn and got stuck in the lane. - Yes, the problem has been confirmed by an independent service center. There was a recall by Mercedes Benz for the same issue in 2020, but for some reason my car isn't included. …”

NHTSA complaint #11666765, filed 2025-06

Engine: “P052E71 Engine Separator and actuator malfunctioning. Was told this fails several times on Mercedes vehicles. I will not pass emissions with this issue. Over $2K to repair and engine light along with code appears. I have videos of the engine light coming off and on. Car has been inspected by Firestone and Mercedes Service Center.”

NHTSA complaint #11572879, filed 2024-02

Body and structure: “On 12/23 I was driving away from home for holiday, and my panoramic sunroof exploded. I was quite shaken as glass was everywhere, in hair, on me and of course in car. I suffered very minor cuts. Called Mercedes SOS. Mercedes customer care. Advised me to go to local dealer near home. 2019 GLC300W4 with ~26,890 miles at time of accident. Dealer, West Chester MB without looking said $10,484. Not under warranty because of year and miles. I see that in March of 2021, about 17,000 vehicles were recalled for sunroof problems, just not my specific model. Clearly, there is a problem.”
