I FIRST THOUGHT SOMEONE HAD BEEN STEALING MY GAS UNTIL MY CAR STARTED TO SMELL LIKE GAS. IF I GIVE SOMEONE A RIDE IN MY CAR, THEY MAKE COMMENTS ABOUT THE SMELL AS SOON AS I START TO DRIVE. MY COWORKERS HAVE NOTICED THE ODOR IN WHEN THEY PASS BY MY CAR IN THE PARKING LOT AND THE SPOTS THAT IT LEAVES ON THE GROUND. I TOOK MY CAR TO THE MECHANIC AND HE SAID MY FUEL PUMP IS LEAKING ON TO THE TOP OF MY FUEL TANK AT AN EXCESSIVE RATE AND IS NOT SAFE TO DRIVE. MY CAR ONLY HAS 84,000 MILES SO I DID SOME RESEARCH ON RECALLS. MERCEDES HAS EXTENDED WARRANTIES ON SEVERAL MODELS FROM 2006-2009 BUT MINE IS NOT ON THE LIST. MY CAR HAS THE SAME PROBLEMS AS THE OTHER VEHICLES EFFECTED. WHAT CAN I DO NEXT?

MERCEDES BENZ VEHICLES MANUFACTURED BETWEEN 2004 & 2007 & EQUIPPED WITH MERCEDES' M272 HAVE A FAULTY BALANCE SHAFT WHICH WAS NOT PROPERLY ANEALED, CAUSING PREMATURE WEAR. THE SUBJECT ENGINES WERE MANUFACTURED WITH DEFECTIVE GEARS IN THEIR BALANCE SHAFTS. THESE DEFECTIVE GEARS WEAR OUT PREMATURELY, EXCESSIVELY, AND CAN CAUSE DAMAGE TO OTHER EXPENSIVE ENGINE COMPONENTS WITHOUT WARNING. REPAIR REQUIRES REMOVAL OF THE ENGINE AND WAS QUOTED AT $7000-$8000 BY THE MERCEDES BENZ DEALER. MOST OTHER IMPORT SHOPS DO NOT WANT TO EVEN ATTEMPT THE REPAIR DUE TO THE COMPLEXITY AND SPECIAL TOOLS REQUIRED. A CLASS ACTION LAWSUIT WAS SETTLED ON THIS ISSUE SEVERAL YEARS AGO (WE WERE NEVER EVEN NOTIFIED) BUT ONLY THOSE WHO HAD THE ISSUE AT THE TIME COULD TAKE ADVANTAGE OF THE SETTLEMENT'S DISCOUNTED REPAIR COSTS (IT WAS A TERRIBLE SETTLEMENT!). WE DID NOT HAVE THE ISSUE UNTIL A FEW MONTHS AGO AT AROUND 77000 MILES. THIS PROBLEM CAN CAUSE THE ENGINE TO MISFIRE, STALL OR BREAK DOWN COMPLETELY. MERCEDES BENZ AND ITS DEALERSHIPS BASICALLY SAY, OH WELL, YOU GOT A LEMON. WE ALSO CANNOT POSSIBLY PASS THE EMISSION TEST WITHOUT REPAIRS THAT COST MORE THAN THE BLUEBOOK VALUE OF THE CAR - WHICH HAS BEEN DEALER MAINTAINED AND GARAGED SINCE PURCHASE. WE BELIEVE THIS BALANCE SHAFT MANUFACTURING FLAW PRESENTS A MAJOR SAFETY ISSUE AND SHOULD BE SUBJECT TO A MANDATORY RECALL AND REPAIRED ENTIRELY AT MERCEDES' EXPENSE.

ON DECEMBER 9, 2016 I TOOK MY 2006 MERCEDES-BENZ CLK350 TO THE DEALERSHIP BECAUSE OF A STRONG ODOR OF GASOLINE COMING FROM THE BACK SEAT AREA. THE DEALERSHIP FOUND THE FUEL SMELL WAS COMING FROM THE LEFT REAR FUEL SENDING UNIT LEAKING. ALTHOUGH I WAS AWARE OF THE EXTENDED WARRANTY AGREEMENT BETWEEN MERCEDES-BENZ AND NHTSA COVERING LEAKING GAS TANK COMPONENTS ON MERCEDES-BENZ CARS, I WAS INFORMED BY THE DEALERSHIP THAT THE AGREEMENT DID NOT INCLUDE GAS TANK LEAKS ON MY CLK VEHICLE, DESPITE THE FACT THAT THE SAME GAS TANK LEAK WAS COVERED ON OTHER MERCEDES-BENZ VEHICLES. THUS, I HAD TO PAY FOR THE EXPENSIVE REPAIR OUT OF POCKET. I AM REQUESTING THAT NHTSA AMEND YOUR PRIOR AGREEMENT WITH MERCEDES-BENZ TO INCLUDE ADDITIONAL MODELS SUCH AS MY 2006 CLK 350 WHICH HAVE DEVELOPED SIMILAR LEAKS IN THEIR FUEL TANK COMPONENTS.
