NHTSA Complaint #11486805 — 2013 MERCEDES-BENZ C300

Rear subframe cracked; car has less than 95,000 miles and looks great. My two children of driving age were using the vehicle at the time, driving others as well. Fortunately, I happened to drive it not longer after the issue and took it to the shop immediately. They put it on the lift and saw that the rear subframe was cracked all the way through. As it turns out, it is becoming very common on this make/model--and it is nearly impossible to get a replacement. Mercedes Benz told me maybe sometime in 2023. In addition to having it inspected, I have since been in contact with several dealers and mechanics. Results are invariable: the part is in extremely high demand, Mercedes cannot fill the demand, and the wait is indefinite but long. There were no warning lamps, messages or other symptoms of the problem. In addition to the inconvenience, the car was very dangerous to drive. I am thankful that my son did not seriously injure himself or others while driving. The crack renders the car unstable at anything but the slowest speeds. When one brakes at any speed over about 20-25 mph, the car pulls violently to one side. Simply braking alone could cause a major, even fatal, accident. And any emergency maneuver could be disastrous. The car has been garaged since June awaiting a replacement that I am told will cost between $4000 and $6000! I am left with a vehicle that runs very well--but is unsafe to drive on a public roadway--and no way to repair it. Moreover, Mercedes cannot tell me when the part may become available (likely sometime in 2023).
