I was driving on the highway I hit the brakes as traffic was starting to build up and the car veered into the right lane and all of a sudden and almost got hit by a tractor trailer. It felt so scary, weird when hitting the brakes after that. I took it to my mechanic immediately and he said the rear subframe is rotted out and do not drive this car!!!!!!!!! I asked please get me an estimate on how much to fix. He called me later in the day and said it was a 8 month wait for the part and the mercedes dealer said it is a very very very common problem on these cars. There are thousands and thousands. There is a defect when manufactured and mercedes does not want to do a recall or step up to the plate in the united states. There is a recall in canada and europe that replaces the part. What are they waiting for till some gets hurt seriously or killed. Now I do not have a car to use for who knows how long and mercedes should be ashamed. Please advise. This is a real scary safety issue. Please advise. Thank you [xxx]. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
