NHTSA complaint #10224686, filed 2008-04, 32 miles“Belt tensioner makes loud metallic noise around the engine area. Car wouldn't start. Camshaft adjuster magnets replaced. Water leak from sun roof drain side mirror cracked under cold weather.”
NHTSA complaint #10714160, filed 2015-05, 60,000 miles“My car has 85,000 miles on it and the Rear Trailing Arm Frame on the drivers side has rusted from the inside out. It is a good thing I have become aware of this, as it was about to break and cause me to lose control of my car. This needs to be recalled before someone gets hurt. In Canada and Germany Mercedes is fixing this for free. Why have Americans not been warned about this potentially deadly safety issue? I am reading many common experiences of cars with less than 50,000 miles on them.”
