What 2012 Mercedes-Benz C204.9 owners say
Most recent owner complaints, unedited.
My vehicle started to pull left when braking. Had all brakes replaced and pulling conitnued. After further review, found out that the rear crossmember / sub-frame was rotted on the driver side. When braking, the rear driver side wheel shifts. You can see the rear caliper move up. The problem is that the subframe is so rotted that it shifts the arms coming off of it (either trailing or torque arm), causing a dangerous shift in the brake/wheel. Called mercedes customer support and all they offered was a small discount on the full repair cost, which of course is already overpriced. My vehicle is 8 years old, garage kept, original owners, and only has about 45,000 miles on it. Nothing else on the car is rotted. This is obviously a quality control issue by the manufacturer. Upon further review, this is a common problem for 2008-2015 mercedes vehicles.
Timing chain tensioner all oil changes were done perfectly with the correct oil and original filter.
