2009 Mercedes-Benz C-Class Powertrain & Transmission Problems

Rear Subframe gets rusted and breaks is an issue with most of mercedes c300 to the point the part is back order in USA and Germany its a safety issue and there should be a recall for it when I called mercedes benz they told me they get at least 3 to 4 calls a day about that issue and people can't find the part it's a comment issue and it sounds be resolved.

TOTAL 4 WHEELS LOCK AT HIGHWAY SPEED WITHOUT ANY WARNING. RECENTLY, A VERY UNSAFE INCIDENT HAS OCCURRED TO ME WHILE I WAS DRIVING ON THE HIGHWAY. I WAS DRIVING ON 202 SOUTH HEADING TOWARDS WEST CHESTER, PA NORTH OF EXIT 29; MY SPEED WAS ABOUT 50 MPH. ALL OF A SUDDEN THE CAR WENT FROM 50 MPH TO A COMPLETELY UNCONTROLLED FULL STOP WITH 1 TO 2 SECONDS. THE TIRES LEFT SKID MARKS ON THE ROAD. THE SEAT BELTS AVOID ME FROM BEING THROWN OUT OF THE CAR. I TRIED TO MOVE THE CAR IN ORDER TO AVOID TRAFFIC COMING AT ME AT 50 MPH BUT I COULD NOT. THE WHEELS OF THE CAR SUDDENLY LOCKED UP AND THE CAR COULD NOT BE MOVED. LUCKILY, THE CAR BEHIND ME WAS ABLE TO STOP WITHOUT ANYONE GETTING HEART. ALSO ALL THE INCOMING CAR AT THE HIGHWAY SPEED WERE ABLE TO SUDDENLY AVOID HITTING ME. THIS INCIDENT OCCURRED WITHOUT ANY WARNING OR ANY INDICATION THAT THERE IS A PROBLEM WITH THE CAR. THIS COULD HAVE BEEN A MULTI CAR ACCIDENT WITH POSSIBLE MAJOR INJURIES OR POSSIBLE FATALITIES. THE POLICE COULD NOT BELIEVE THAT THIS CAN HAPPEN AND THEY HAVE NEVER ANYTHING LIKE THIS BEFORE. THE CAR WAS TOWED TO THE MERCEDES DEALER. THE DEALER CALLED ME BACK TELLING ME THAT IT WAS THE SUDDEN FAILURE OF THE FRONT DIFFERENTIAL WITHOUT ANY WARNING. I CALLED MERCEDES AND THEY RESPONDED BY SAYING THAT THERE WAS A LEAK IN THE TRANSFER CASE. I INDICATED THAT THE CAR IS PARKED IN A GARAGE AND I WOULD HAVE SEEN THE LEAK FROM THE TRANSFER CASE. I WOULD LIKE THIS INCIDENT BE SERIOUSLY REVIEWED BY MERCEDES IN ORDER TO AVOID THIS FROM OCCURRING ON THE ROAD AGAIN AND BY THE DEPARTMENT OF TRANSPORTATION OR OTHER GOVERNMENT AUTHORITIES. AGAIN, LUCKILY NO ONE WAS HURT. *TR
