NHTSA Complaint #11479472 — 2011 MERCEDES-BENZ C300

08/15/2022 (date statement was wrote not date of incident) While driving into work at 50 miles an hour, traffic started to slow. While applying brake heard loud pop and vehicle rear end lounged right making steering difficult, I immediately released the brake and control came back I then gently applied the brake again to slow vehicle and felt slight clump from rear. This was very disconcerting my vehicle never had performed in that manner which made me feel very uncomfortable continuing driving, I had mechanic look at vehicle and was told the rear subframe had rusted and the rear left control arm broke away from frame??? My vehicle is very well maintain and just a little over 11 years old. Feeling belittled I began investing Mercedes’ forums and found this has been an issue with some of not all models and nothing has been done to correct this defect. I contacted Mercedes’ Benz and the service department knew exactly what it was and stated the is no recall on these failing subframe due to rust. This is a very serious safety issue due to the fact of loosing control of the vehicle when this component fails possibly causing serious injury or even death. To put insult to injury Mercedes has no plan to replace it and it’s left to the consumer to replace this non maintenance item. Looking into forums about this issue these subframes have failed at almost every odometer mileages, particularly the w204 chassis 2008-2014. A safety recall should be advised to the consumers whom own such vehicles!! Safety First!!!!!!!!!
