NHTSA Complaint #11608926 — 2015 MERCEDES-BENZ C300

The rear subframe is rusted through. It is a known manufacturing defect where water sits and rusts through the subframe. This was a recall on various Mercedes up through 2014. Multiple 2015 models have the same issue, including my Mercedes 2015 C300 4MATIC. I have a 2009 SLK with the same issue, which Mercedes previously fixed and acknowledged the manufacturing defect. The part number under the recall through 2014 is "212 250 3805" My 2015 car has part number "212 350 3605" that is not covered but still has rust issues. See attached picture The subframe can result in the back wheels falling off. My subframe is severely rusted through and a risk as a driver. A certified Mercedes dealer has inspected this issue and confirmed the safety but Mercedes will not cover the repairs for the known defect. There are no warning lights or indicators to this issue.
