GEAR SHIFTER WILL GET STUCK IN PARK WHEN PARKED ON A SLIGHT INCLINE, SUCH AS A DRIVEWAY OR SMALL HILL. I ABSOLUTELY HAVE TO PARK ON A FLAT SURFACE IF I WANT TO GET MY SHIFTER OUT OF PARK. I HAVE TO TAP ON THE TOP OF THE SHIFTER AND CONTINUE TO TRY TO GET IT OUT OF PARK. THIS CAN TAKE ANYWHERE FROM 10-30 MINUTES AND HAS HAPPENED MULTIPLE TIMES. VERY FRUSTRATING AND I'VE ONLY HAD THE CAR A COUPLE OF MONTHS. NOW I HAVE TO PUT MONEY IN TO FIX IT ALREADY. WHY IS THERE NOT A RECALL ON THESE VEHICLES WITH THIS PROBLEM? FROM MY RESEARCH, IT SEEMS AS THOUGH PLENTY OF MERCEDES HAS THIS PROBLEM.

SPEED DEPENDENT FRONT END NOISE AND VIBRATION. INSPECTION BY MB AUTHORIZED DEALER INDICATES: "FRONT TRANSFER CASE COMING APART". MB CUSTOMER SERVICE INDICATES THAT THE PROBLEM IS A "ONE OFF" BUT OFFERED A 50% DISCOUNT ON REPAIR. REPAIR COST IS $7000. SUSPECT THAT THIS IS NOT A "ONE OFF" AND THE PROBLEM IS MORE FREQUENT GIVEN THE IMMEDIATE OFFER OF A DISCOUNT ON REPAIR. FAILURE OF THE FRONT TRANSFER CASE AT ANY SPEED CAN AND MOST LIKELY WILL CAUSE WHEEL LOCK UP, ENGINE FAILURE, LOSS OF POWER ASSISTED CONTROLS (STEERING AND BRAKING), LOSS OF ELECTRICAL SYSTEMS (AIR BAGS), AND POSSIBLY CREATED AN ACCIDENT WITH FATALITIES. *TR

ON 12/22/12 AT APPROXIMATELY 9PM I WAS PARKING MY CAR HAVING ARRIVED AT MY DESTINATION. I HAD ALMOST FINISHED PARKING WHEN MY MERCEDES BENZ C300, 2010 LUNCHED FORWARD WITHOUT WARNING AND HIT THE TRUCK IN FRONT OF ME RESULTING IN A CHAIN RECTION. WITH THAT TRUCK SMASHING INTO THE VEHICLE INFRONT OF IT. I HONESTLY BELIEVE THAT THE VEHICLE SUDDENLY ACCELERATED ON ITS OWN AND THEREFORE MUST HAVE MALFUNCTIONED. I WENT SEARCHING AND FOUND SIMILAR COMPLAINTS FROM A COUPLE OF OTHER OWNERS OF BENZ C300 2010 MODEL.I CALLED MERCEDES BENZ USA AND REPORTED AND WAS TOLD THAT I NEED TO TAKE THE CAR IN AND PAY FOR IT TO BE DIAGNOSED. THEY INSISTED THAT THEY HAVE NOT HEARD OF ANY SIMILAR COMPLAINT. I AM CONCERNED THAT THIS MAY HAPPEN AGAIN. *TR
ON JULY 18, 2011, I WAS WAITING IN A LINE OF TRAFFIC FOR A SIGNAL LIGHT TO CHANGE, AND AS THE VEHICLE IN FRONT OF ME BEGAN TO MOVE, I TOOK MY FOOT OFF THE BRAKE AND MY 2010 MERCEDES BENZ C300 LURCHED FORWARD AND REARENDED THE VEHICLE IN FRONT OF ME. THE FORWARD MOTION WAS VERY FORCEFUL AND THE IMPACT WAS HEAVY. THIS WAS UNINTENTIONAL ACCELERATION, AS I HAD NOT DEPRESSED TO ACCELERATOR AND WHILE I AM DEEMED AT FAULT I FEEL THIS MOVEMENT IS DEFINITELY RELATED TO ANOTHER INCIDENT IN THIS VEHICLE REPORTED ON MAY 21, 2011. PLEASE REFER TO ODI # 10403924. MERCEDES BENZ CORP SAYS THERE IS NOTHING WRONG WITH THIS VEHICLE. I WOULD LIKE AN INVESTIGATION TO THIS PROBLEM, SINCE THERE IS EVIDENCE OTHERS HAVE REPORTED THE SAME PROBLEM. *KB
