The driver's side interior door handle became disengaged as I was trying to open the door so I was momentarily trapped inside. If I had been in a situation where I had been in an accident and needed to get out quickly, or the car had been on fire, or I was stalled on the train tracks, this could have been a serious incident. When I googled this, it sounds like this is a very common occurrence in Mercedes. There was no warning that this was going to occur - everything seemed secure before this happened. I have taken it to a service center for a very expensive repair as they have to remove the door panel, replace/reattach the part and put the door panel back.

The driver's side door handle broke impossible to open door from inside if there was an accident. I have been told that this is a common problem with my car, and that it cost $1600 to replace repair at the dealer. This is such a common problem that there are after market kits to repair the broken handle for $20, but including labor the repair is $500.
