A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

Good evening, I drive a 2008 mercedes benz c300 sport which I financed from a VW dealer, which sold it as a pre owned/used vehicle still under warranty, regardless, I opted to ensure I had the maximum warranty available. On thursday, sept 03 I was involved in an accident while operating this vehicle. Inside the vehicle was a front passenger and a rear passenger as well, neither of whom I think were wearing seat belts.

Reported at 31,000 miles, September 2009 CrashInjury

I was edging out of a parking space in a supermarket parking lot. I stepped on the brake pedal to allow another car to pass. My car suddenly surged ahead, hitting five other vehicles and a pedestrian, before smashing into a barrier that stopped it. I was pushing hard on the brake petal throughout, but it had no effect on stopping the car. It is of course possible that I stepped on the gas pedal and not the brake pedal.

While driving all of a sudden the steering stopped working. It turned freely both sides but the car was going straight. It happened on a city road. If it happened on a highway it would be a disaster.
