“The piece of plastic that serves as an attachment for the pull cord from the inside door handle broke. This made it impossible to open the front passenger door from the inside. I believe this is a safety hazard since the passenger is trapped inside the car and cannot exit easily. In an accident situation, this would be a real hazard. I discussed with local dealer, who advised this happens all the time.”
NHTSA complaint #10680906, filed 2015-02, 61,698 miles“Driver's side inner door handle broke. Cannot exit from car and need to open door from outside. Could be a problem in the event of an emergency if one needs to exit a vehicle in a hurry. I believe this is a common problem with mercedes benz from my research.”
NHTSA complaint #10661313, filed 2014-11, 75,000 miles“I went to open my door after I had parked and the driver side door latch broke. So, I had to cut my car back on, roll the window down and pull the latch from outside the door. If you look online this appears t be a common problem with the 2010 C300.”
NHTSA complaint #10662581, filed 2014-12, 74,867 miles“My door handle broke stranding me in my seat. I had to crawl across the seat and exit the passenger side door.

When I applied the brakes, I experienced a failure of the rear cross-member subframe which caused the rear left wheel to deviate in a such a way that caused the rear of the vehicle to fishtail. I had to fight to regain control of the vehicle and avoid a head-on collision. I drove the vehicle to a nearby mechanic who pointed to a break in the sub-frame where the rear-left tire suspension components attached to the rest of the car. …”
