NHTSA Complaint #11477837 — 2012 MERCEDES-BENZ C300

2012 Mercedes Benz C300 4-Matic; Failure of rear subframe, significant crack of an important support member; very limited minor corrosion of the other parts of the frame, seems to be a manufacturing quality defect in a very specific part. Vehicle has been inspected by a highly qualified independent mechanic and by the closest manufacture's dealer in Massachusetts. Car cannot be driven because it is unsafe to do so. Both the dealer's service department and the independent repair shop have advised and confirmed this. Limited research online seems to indicate that this problem is well known by Mercedes Benz, and the manufacturer has issued recalls in other countries and has taken some responsibility for this defect. However, in the USA, Mercedes Benz has not issued a recall, to the best of my knowledge. It certainly seems that they should have done so. It is highly likely that many owners with this problem lack the knowledge or experience needed to report this problem to the appropriate authorities. I happen to have an above average knowledge regarding automobiles. I first became aware of this problem in Nov., 2021. The vehicle is available for inspection by your department if you deem appropriate.
