2014 Mercedes-Benz C300 Suspension Problems

“R/f tire bubble in sidewall. At 1959 miles a bubble appeared in the r/f tire. I discovered the bubble while washing the car . This appeared about two month after purchase.

“Failed component: The subframe on my Mercedes C300 broke on one side and was almost broken on the other. It would be available for inspection as it is sitting in the Mercedes dealer bone yard waiting on the part to be shipped from Germany around September 17th. It also ruined my back tires & now I have to replace them too. I understand that in the UK the Mercedes dealers are fixing this problem free of charge but there seems to be no recalls! Safety: I was entering the freeway on a rainy afternoon. My car was fishtailing very badly. …”

“My 2014 Mercedes C300 4matic currently has a rusted through rear subframe. I know this has been reported to your Bureau numerous times by various people. This affects all 2008-2014 C Class and E Class Mercedes (as I used to work for a Mercedes dealer). Mercedes is trying to avoid liability at the sheer cost and man hours required to replace these parts. This is a MAJOR safety hazard, and has caused numerous drivers to lose control of their vehicle when they do in fact break off at one of the weld joints. The car is 8 years old with approximately 90k miles. …”

“Car has approximately 60,000. miles. Upon it's state inspection Mercedes Benz service center indicated rear subframe is rusted. Service advisory says it is okay now, but will need to be replaced. Searching Mercedes forums, I've noted this is a n oft reported issue. Many do not realize there is an issue until it breaks and car pulls to one side at rear upon braking. Others have experienced rusted brake lines at the same area as the subframe issue. Others have noted damage to the gas tank from suspension parts banging the fuel tank after it breaks. I realize this is a 8 year old vehicle. …”
