I had just exited the freeway, and slowing down for a stop light when I heard a loud crack. The front drivers side coil spring socket that connects to the unibody had rusted and broke, dropping the suspension on top the tire. I took the car to the Mercedes dealership, and they told me that the right passenger side coil socket was rusted as well. The dealership also mentioned that it's a common problem but Mercedes had yet to address the issue.

Front bumper cover / air dam broke on ordinary wheel stop in public parking lot. Car has inadequate clearance and front bumper cover / air dam is constructed so that it hooks on wheel stops and breaks. It happens every time you park if you bring the front tires to within a foot of the wheel stops. According to mbusa, the front bumper cover is an air foil / safety device providing stability to the car. Once it is broken, the entire front bumper cover has to be replaced, but of course it will only happen again and again.
