Example complaints

Engine: “Over the last couple of days, my car has displayed the Engine Warning message intermittently. I took this to the dealership for inspection and received the following fault code: P06DA00 - Inoperative Oil Pump Valve. For a car with low mileage, this could potentially be a car issue. The estimated total cost for labor and parts is over $5k. I think there are more cars affected.”

NHTSA complaint #11666806, filed 2025-06

Other or unknown: “Please see attached pdf. It concerns the trunk opening and closing mechanism which is supposed to signal when something is in the way before it closes. The trunk closed without warning on my head. Mercedes refuses to disconnect the trunk latch feature because I will not sign a release, which I will not do. See attached incident report filed with mb.”

NHTSA complaint #11374322, filed 2020-11, 400 miles

Electrical system: “There was smoke coming from from the engine compartment and spontaneous fire started while the car was at a stop light. The car was totally damaged. The car has less than 15000 miles driven. It is still under warranty. Information was sent to Mercedes-Benz USA with a certified mail and immediately via email from the dealership. Also was reported where the vehicle was stored if they wanted to investigate the engine. Benz USA just wanted me to fill out their standard report form. The towing company also told me that they had to tow another Benz not long ago from engine fire.”

NHTSA complaint #11616110, filed 2024-09

Fuel system: “The contact owns a 2020 Mercedes-Benz E350. The contact stated that while driving at an undisclosed speed, the contact detected an abnormally strong fuel odor inside the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic and the dealer, who determined that the fuel injector in cylinder #3 needed to be replaced. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 21V961000 (Fuel System, Gasoline); however, the VIN was not included in the recall. …”
