NHTSA Complaint #10378052 — 2006 MERCEDES BENZ C230

THE ENGINE LIGHT WENT ON IN MY 2006 C230 MERCEDES (CURRENT MILEAGE 57,000) SINCE SEPT 2010. I LATER CONFIRMED IT'S THE PROBLEM IN THE BALANCE SHAFT, WHICH DIRECTLY IMPACT ON THE ACCELERATION AND FAILURE OF THE ENGINE. THE ENGINE SUDDEN STOPPED RUNNING FEW TIMES IN MY COMMUTE TO WORK IN A FREEWAY. LUCKILY, IT WAS DURING THE RUSH HOUR AND THE TRAFFIC WAS MOVING SLOWLY. MANY TIMES WHEN I ENTERED TO THE FREEWAY IN A MERGE LANE, THE ACCELERATION DIDN'T WORK AT ALL AND I ALMOST GOT HIT BY THE OTHER CARS IN THE MERGE LANE. THE MECHANIC ADVISED IF CONTINUE DRIVING THE VEHICLE WITHOUT REPLACING BALANCE SHAFT WILL LEAD TO A BIG DANGER TO THE DRIVER AND PASSENGER SINCE THE ENGINE CAN BE STOPPED ANYWHERE AND ANYTIME. REPLACING THE BALANCE SHAFT COST $6,000 (FROM THE DEALER) AND MERCEDES USA REFUSE TO COVER ANY PORTION OF THE REPAIR SINCE MY CAR EXCEEDS 50,000 MILES/4 YRS WARRANTY. I TALKED TO THE DEALER AND THE SERVICE ADVISER. THEY SAID THIS IS A COMMON KNOWN PROBLEM FOR MANY OF THE MERCEDES MODELS. IN FACT, IT WAS IN THEIR SERVICE BULLETIN SINCE 2007. UNFORTUNATELY MERCEDES WOULDN'T COVER ANY REPAIR UNLESS THERE?S A RECALL OR SOMEONE DIE FROM IT. I WONDER IF MERCEDES WILL WAIT UNTIL MORE INJURIES BEFORE THEY CONSIDER STOP USING THE SAME BALANCE SHAFT IN THEIR CARS. THIS BALANCE SHAFT IS A VERY SMALL PIECE LOCATED RIGHT IN THE MIDDLE OF THE ENGINE. THE COST OF THE MATERIAL IS VERY INEXPENSIVE. HOWEVER, IT REQUIRES INTENSIVE LABOR BECAUSE THE ENGINE MUST BE TAKEN APART IN ORDER TO REPLACE THE BALANCE SHAFT. *TR
