One problem related to door hinge has been reported for the 2002 Mercedes Benz C Class. The most recently reported issues are listed below.
The inside front door handle of c-class (year2002 or similar) is no good, if you park the car on the down slope street, and close the front door from wide open position, the door handle will give away and broken apart at the top end which is attached to the inside door panel only with a small plastic stud. I sent the complaint letters to Mercedes Benz USA as well as Mercedes Benz of san francisco, they never response. I believe the failure of the door handle to perform properly because of faulty design and the manufacture has to bear responsible by recalling this type of door handle.
