The rear subframe is broken. I was braking and the car lost control about two weeks ago. Ever since then the car feels like it's slipping whenever I brake or on a turn. I lose control of the car and I'm endangering my life and others. I went to take my vehicle to get inspected today and the said the rear subframe is broken and no fault of my own. The car was kept in a garage for years and only has 55k miles on it. There's no reason a subframe should be broken.
In having maintenance on my vehicle, the dealer advised that the subframe is corroding and needs to be replaced. I searched several Mercedes forums and found a number of owners citing similar corroding subframes yet no other undercarriage components showed rust or corrosion. All owners felt that this should be remedied by Mercedes before a failure causes injuries. Forum participants suggested and encouraged to file a complaint to the federal safety agency for investigation.
I found that the subframe had been recalled in other countries, but not in the united states? The large number of failures on this subframe across multiple models is concerning. This is a gross failure of a major safety component that can cause serious injury or death. My research showed this part has been recalled in Canada; MBUSA feels the need to wait to do so until a serious injury or death has occurred. The defective subframe is known and the new part’s design has been amended to take into account this rust issue. This is especially concerning considering the recent recall on the brake boosters due to advanced corrosion. MBUSA’s decision exhibits a lack of accountability for a defective part and this issue needs to be promptly addressed for the safety of its customers.
