The contact stated that her boyfriend and son helped to push the vehicle to the right side of the roadway. The contact smelled a burning odor but was unsure where the odor was coming from. No warning light was illuminated. The contact stated that an independent mechanic was contacted. The vehicle was towed to an independent mechanic where it was diagnosed that the ECU was damaged and needed to be replaced. The vehicle was repaired.

The contact owns a 2008 Mercedes-Benz C300. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. Additionally, the check engine warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed with an intake manifold failure. The contact was informed that the intake manifold needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 152,151.

Error codes 1200 and 1208 regarding the lack of tension on the timing belt due to a worn sprocket. It was certified by two different Mercedes Benz mechanics with ample experience with these cars. Vehicle still runs but I was warned to stop it and fix it before it is a major problem.

MANIFOLD INTAKE CONTROL ARM BROKE AT AROUND 67,000 MILES CAUSING MAJOR ACCELERATION PROBLEMS PRIMARILY IN FIRST AND SECOND GEAR AT LOW RPMS. IT WAS A SAFETY CONCERN DUE TO RUSH HOUR TRAFFIC. AFTER INSPECTING DESIGN OF INTAKE MANIFOLD, THERE ARE MANY PLASTIC PARTS THAT CAN BREAK OFF AND ENTER THE ENGINE CAUSING IRREPAIRABLE DAMAGE TO THE ENGINE. THE CONSEQUENCES OF THIS HAPPENING ON THE FREEWAY AT HIGH SPEED ARE UNIMAGINABLE.

MY INTAKE MANIFOLD KEEPS BRAKING PART#272-150-24-01. THE FRONT PLASTIC PIECE THAT OPENS THE BAFFLES KEEPS SNAPING THIS IS THE SECOND ONE I BUY IN THE PAST 2 YEARS EACH TIME I PAID $1281.00+LABOR THEY NEED TO MAKE SOMETHING MORE STRONGER THANT THIS, IS A WASTE OF MONEY TO KEEP BUYING THIS.

TWO SEPARATE INSTANCES OF COMMANDED ACCELERATION WITH 2008 MERCEDES C300. PURCHASED THE CAR FROM A PRIVATE USED CAR DEALER IN SEPTEMBER 2009 WITH 10,500 MILES. ON NOVEMBER 1, 2009 I EXPERIENCED FIRST INSTANCE OF UNCOMMANDED ACCELERATION WHILE SLOWING TO A STOP IN A DRIVEWAY. ENGINE SUDDENLY ACCELERATED TO A HIGH RATE AND STRUCK A PARKED TRUCK IMMEDIATELY IN FRONT OF CAR. SHIFTED INTO REVERSE AND CAR SPED AT MAXIMUM RPM ACROSS LAWNS AND STREET UNTIL FINALLY RETURNING TO NORMAL. AT NO TIME WERE THE BRAKES ABLE TO HAVE ANY EFFECT ON SLOWING MY SPEED. THIS INCIDENT WAS NOT REPORTED TO POLICE SINCE NO SERIOUS PROPERTY DAMAGE OCCURRED. HOWEVER, I IMMEDIATELY CONTACTED DEALER FROM WHOM WE PURCHASED THE CAR. THEY CLAIMED WE NEEDED TO CONTACT MERCEDES SINCE CAR WAS STILL UNDER WARRANTY. WHEN I VISITED THE LOCAL MERCEDES DEALER THE FOLLOWING DAY, THEY INITIALLY EXPRESSED INTEREST IN INSPECTING THE CAR RIGHT AWAY HOWEVER NEARLY 2 WEEKS PASSED BEFORE THEY TOLD US TO BRING THE CAR IN FOR INSPECTION. THEY KEPT THE CAR FOR 3 DAYS AND TOLD US THEY FOUND NO MECHANICAL OR ELECTRICAL FAULTS. WE WERE GREATLY DISAPPOINTED WITH THEIR FINDINGS AND SENT A CERTIFIED LETTER TO MERCEDES USA WITH FULL DETAILS OF THE INCIDENT. THEIR REACTION WAS THAT THE VEHICLE WAS OPERATING AS DESIGNED. WE CONTINUED TO OPERATE THE VEHICLE AND ON MAY 21, 2010 A SECOND INSTANCE OF SUDDEN UNCOMMANDED RAPID ACCELERATION OCCURRED. I WAS PULLING OUT OF MY DRIVEWAY AT A SLOW RATE WHILE SLOWING TO A STOP AS ANOTHER VEHICLE PASSED BY. SUDDENLY, THE MERCEDES ACCELERATED UNCONTROLLABLY AND STRUCK THE PASSING VEHICLE CAUSING IT TO OVERTURN. THE CIRCUMSTANCES WERE NEARLY IDENTICAL AND I AM POSITIVE THE GAS PEDAL WAS NOT BEING DEPRESSED. CAR HAS BLUETOOTH CAPABILITY AND I HAVE A BLUETOOTH COMPATIBLE CELL PHONE. PERHAPS THIS CAUSED INTERFERENCE WITH SOMETHING IN THE ENGINE COMPUTER SYSTEM. MY CAR IS PRESENTLY IN AN UNDRIVEABLE CONDITION AND MERCEDES HAS NOT YET COME TO INSPECT IT.

MY CAR SMELLS LIKE MILDEW AND MOLDY. I HAVE TAKEN IT TO THE DEALER ABOUT 3 TIMES ABOUT THIS SITUATION. I HAVE RESPIRATORY PROBLEMS AND ALLERGIES AND I CAN HARDLY USED THIS CAR, IT STINKS AND BOTHERS MY BREATHING. *TR
