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.

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.

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.

My door handle broke stranding me in my seat. I had to crawl across the seat and exit the passenger side door. The dealer stated that they had fixed 7 so far this year. Safety issue that I can not get out of the car and they refuse to fix the issue.
