The subframe and the brake lines are very faulty in this car when it comes to its design. The subframe and brake lines rust easily and are cheaply made for this car. My car break down while driving making it hard to have pressure on the brakes. My incident was around the school area. There were no accidents or collisions Involved. It could happen to adults and children. The dealer never confirmed this problem before selling it to me. Another manufacturer told me about this problem. The car showed warning signs like the braking system and brake fluid. The brake fuel was leaking. The problem appeared when I started the car.

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!!!!!!!!!

The rear subframe is rusted and broken, alignment is out, and steering wheel is off centered. Given the history of this model car, it has been under recall in multiple countries outside the United States. This is a common and very dangerous issue that needs to be addressed in the United States because if you call any auto shop or Mercedes they all say it is a common problem with 2008-2014 C-class models. When you look up this issue with this car it has multiple threads saying that the rear subframe has rusted and broke when it is not supposed to.

My 2011, 300C has 116,000 miles. Driving the car I notices that when I applied brakes car swayed to the left. Concerned I brought vehicle to MB in Paramus, NJ. Was told that rear sub-frame was rusted and dislodged along with the brake lines, also rusted. Car was serviced every 10k miles as recommended by dealer and just now these issues were identified. I recently also was told that the fuel tank was also rusted out and needed to be replaced. These issued were a danger to me and my family and could have resulted in potential deaths. MB does not have any recalls for these problems but I believe NHTSA should initiate a recall as many others have had these problems. A google search has identifies a large number of people having these same problems. Below are 2 videos of the problem. https://app.mykaarma.com/service-cart/mpi/BfGpB6lKrWaYxN3TKQFzqa2MgCzxYgihmma6Ker7cFE/check/Your_CAR_CHECK_ID/media/0/view/1 https://api.mykaarma.com/video-walkaround/details?inspection_uuid=629e0e431dd41d3dfba54fd1&fileType=video No warnings messages or previous symptoms occurred and even though car was serviced every 10k miles, dealer Neve identified any of the concerns. How can that be when brake lines are rusted. Dealer refuses to take any responsibility and MB Germany has yet to respond to my various emails. Please review as these issues have life and death implications and a Recall should be initiated by NHTSA.

The contact owned a 2011 Mercedes Benz C300. While at a stop, the accelerator pedal was applied and the vehicle violently accelerated to 30 mph. The brake pedal was depressed, but failed to respond causing the contact to crash into the rear end of another vehicle. The steering wheel and the steering column air bags deployed. As a result, the contact sustained knee and back injuries that required medical attention. A police report was filed. The vehicle was destroyed. The manufacturer was notified of the failure. The approximate failure mileage was 10,000.
