BOTH REAR BRAKE LIGHT ASSEMBLIES HAVE FAILED. THESE FAILURES INCREASE THE LIKELIHOOD OF A REAR END COLLISION. WHEN THE LEFT ASSEMBLY FAILED IN 2011, I ATTRIBUTED IT TO BAD LUCK. WHEN THE RIGHT ASSEMBLY FAILED AT 66000 MILES IN 2012, IT OCCURRED TO ME THAT MERCEDES MAY HAVE A PROBLEM THAT DESERVES A RECALL ACTION. INSTEAD OF COSTING ABOUT $5 TO $10 FOR LIGHT BULBS THESE ASSEMBLIES COST ABOUT $300 EACH TO REPLACE AND INSTALL. $600 IS ENOUGH TO CAUSE SOME PEOPLE TO NOT REPAIR THEM AND THUS CREATE A SAFETY HAZARD.

TRANSMISSION IS HAVING PROBLEMS ACCELERATING AND SHIFTING GEARS. WOULD "REV" UP THEN NOT SHIFT AND NOT ALLOW MY CAR TO ACCELERATE WHILE I WAS ON THE HIGHWAY, CAUSING CARS TO BACK UP BEHIND ME AND PUTTING ME IN DANGER. AT OTHER TIMES IT WILL NOT ALLOW ME TO EVEN ACCELERATE. HAVE TO CONSISTENTLY RESTART MY CAR IN DANGEROUS PLACES ON THE ROAD TO GET IT TO EVENTUALLY WORK. WENT BY BODY SHOP AND TURNS OUT TO BE A SPEED SENSOR CODE ISSUE WITH THE TRANSMISSION. NEEDS SOME FORM OF A VALVE BODY REPAIR, BUT UNSURE TO WHAT EXTENT. THIS IS ONE OF…

MY WIFE NOTICED THE REAR PASSENGER SIDE SEATBELT WAS NOT WORKING PROPERLY. IT WOULD NOT "CATCH" OR RETRACT AFTER BEING PULLED OUT. TOOK TO DEALER. THEY VERIFIED THE TENSIONER WAS BAD AND HAD TO REPLACE THE TENSIONER & SEAT BELT ASSEMBLY. IT WAS NOT COVERED BY THE ORIGINAL OR EXTENDED WARRANTY. I HAD TO PAY $551. I'VE NEVER HEARD OF THIS HAPPENING ON THIS LOW OF MILES. IT'S A VERY IMPORTANT BASIC SAFETY DEVICE. THEY HAD THE PARTS IN STOCK WHICH MADE ME THINK THIS COULD BE A COMMON PROBLEM. *TR

AT 57,000 THE RACK AND PINION SEALS WENT OUT ON THE STEERING MAKING THE CAR EXTREMELY DIFFICULT TO STEER. REAR SEAT BELTS HAD NEVER BEEN USED UNTIL 12/1/14 AT WHICH TIME I FOUND THEY WERE NOT USABLE.
