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).
