| Wheel problems |
Rear brakes backing plates rotted prematurely despite garage kept and well maintained status. While driving, noticed loud scraping and grinding noises from the rear left wheel. Took to mechanic and he found severe rust, with deep corrosion and flaking "rotted". He said I was lucky because this was very close to causing the entire brake assembly to fail, which would lead to serious braking problems or "locked out wheel" and loss of control on a highway which would have put me and others at risk. Had similar rust issues with this car that were fixed in the recent past including rusted brake lines and rusted rear subframe. There is definitely something wrong with the manufacturing as the rear subframe had been recalled and got it fixed that way less than a year ago.
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.
