The Mercedes Benz C 300W4 2010 has a problem with the inside door latch.the vehicle was bought as a certified preowned from the dealer in 2013. It has less than 15000 miles. I took it to the dealer today they knew what was wrong immediately. Cost to repair approx. $1000. Looking on line I found numerous people complaining about the same problem. There is an obvious design flaw that Mercedes is not willing to accept. What happens in an emergency if you need to get out of the car and the handle breaks? in my humble opinion this is a safety issue that should be looked into.

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.
