2007 Mercedes-Benz S550 Owner Comments

problem #3

S550 8-cyl

  • miles


Worn timing sprocket and balance shaft was defective when I purchase the vehicle in 2011. Mercedes Benz knew about this defective part and did not inform me. The vehicle had 46000 miles on it at the time. If I was inform about this problem I wouldn't have bought it. I believe this is a violation of the consumer protection act.
