Example complaints
Exterior lighting: “The wires within both of my headlights of my 2009 mercedes c300 have their insulation so deteriorated that the wires are fully exposed. This issue causes the lights to cut in and out without warning which have occurred during highways speeds and or rural areas in puerto rico. This dangerous situation is not being taken care of by the manufacturer with various attempts tried.”
NHTSA complaint #10562864, filed 2014-02, 49,000 milesTransmission and drivetrain: “At 43,500 and 54 months the transmission in the car had to be replaced. The car has always been properly serviced at the mercedes dealer. I believe this model/make has defects as I have brought it back for service many times.”
NHTSA complaint #10563723, filed 2014-02, 43,400 milesElectrical system: “The rear tail lights on my mb c350 shows signs of a burning/melting on the connector. I initially received a notice on my dash that the right rear bulb was bad and not working. I checked the connectors and it showed signs of melting/burning. After adjusting the wires, the lights would work until the car would hit a bump and I would have to again reset the wires.”
NHTSA complaint #10525200, filed 2013-07Brakes: “The contact owns a 2009 mercedes benz c300. The contact stated that the vehicle was experiencing several computer defects. While parked on a hill and attempting to place the gear shifter into reverse, the vehicle would roll forward instead of backwards. The vehicle would roll forward approximately one foot as if it were in neutral. During this time, the steering would lock and the brakes would lose power. It would take tremendous force to depress the brake pedal and stop the vehicle. The dealer and manufacturer could not assist with the repairs. There were no recalls available. …”
