What 584 owners told NHTSA about the 2012 Mercedes-benz C-class Coupe

EXTREMELY DANGEROUS FUEL LEAK - FUEL STARTED TO LEAK FROM THE TOP OF THE GAS TANK, INSIDE THE CAR FROM UNDER THE DRIVER SIDE REAR PASSENGER SEAT. VEHICLE WAS TAKEN TO CLOSEST SHOP AVAILABLE WHEN HEAVY FUEL SMELLS WERE NOTICED INSIDE VEHICLE WHILE DRIVING. A LOCAL TIRE SHOP, HAMIL FIRESTONE, LOOKED UNDER THE CAR AND IDENTIFIED THAT FUEL WAS LEAKING DOWN THE FRAME TO THE ROAD. SOMEHOW GASOLINE WAS ACTUALLY LEAKING FROM INSIDE THE CAR. I CONTACTED MERCEDES CORP IMMEDIATELY AND THEY SENT A TOW TRUCK TO COLLECT THE VEHICLE. I WAS TOLD THAT DUE TO THE NATURE OF THE ISSUE IT WAS EXTREMELY DANGEROUS TO DRIVE THE CAR. MERCEDES SAID THAT DESPITE THE CAR BEING OUT OF WARRANTY, SOMETHING LIKE THIS WOULD GO TO "UPPER MGMT" FOR REVIEW AND SHOULD BE TAKEN CARE OF BY MERCCEDES. NOW THE VEHICHLE IS STILL AT THE LOCAL MERCEDES DEALERSHIP WHERE THE HAVE CONFIRMED AN ISSUE WITH THE FUEL PUMP AND SEALS, AND THAT THE CAR IS DEFINETLY LESKING FUEL OUT ONTO THE ROAD.... BUT DESPITE A RECALL ON ALMOST EVERY OTHER 2012 MODEL CAR FOR THE SAME ISSUE, THEY ARE SAYING BECAUSE THIS VIN IS NOT INCLUDED IT DOESN'T MATTER THAT IT IS DOING THE SAME THING. THEY WANT ME TO PAY FOR THE REPAIR. I EXPLAINED THAT I OR MY CHILDREN, OR EVEN ALL OF US COULD HAVE BEEN INVOLVED IN A FATAL CAR FIRE DUE TO THE ISSUE!!! MERCEDES DIRECT RESPONSE WAS, "THAT IS THE RISK OF DRIVING A VEHICLE OUT OF WARRANTY." UNACCEPTABLE!!!

THERE ARE SMALL CRACKS THAT HAVE DEVELOPED IN THE TOP OF THE FUEL SENDING UNIT. THIS ALLOWS FUEL TO LEAK OUT OF THE TOP OF THE FUEL PUMP AND POOL IN THE CENTER OF THE PUMP WHERE THERE ARE A NUMBER OF ELECTRICAL WIRES THAT ARE SUBMERGED IN FUEL. THIS IS A POTENTIALLY DEADLY PROBLEM AS THERE IS A REAL POTENTIAL FOR IGNITION OF THE LEAKED FUEL WHICH IS RIGHT UNDERNEATH THE DRIVERS SIDE PASSENGER SEAT WHERE MY 5 YEAR OLD'S CHILD SEAT IS LOCATED. THERE IS ALSO AN EXTREMELY STRONG ODOR OF GAS INSIDE THE CAR WHICH IS STRONG ENOUGH TO CAUSE LIGHT HEADEDNESS AND POSSIBLE SYNCOPE. THIS IS AN EXTREMELY DANGEROUS SITUATION. THE NTSB OPENED UP AN INVESTIGATION OF THIS ISSUE THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION OPENED A PROBE IN JANUARY 2012 AFTER RECEIVING 20 REPORTS IN 2003-2006 E55 AMG VEHICLES AND EXPANDED THE PROBE LAST YEAR INTO ALL 2003-2008 E-CLASS VEHICLES. OWNERS SAID THEY REPORTED A STRONG ODOR OF GASOLINE FUEL BOTH INSIDE AND OUTSIDE OF THEIR VEHICLE, PARTICULARLY AFTER REFILLING THE FUEL TANK. MANY COMPLAINTS SAID THE ODOR SUBSIDED AFTER DRIVING SOME DISTANCE THEREBY LOWERING THE FUEL LEVEL IN THE TANK. OTHER OWNERS REPORTED THEY WOULD ONLY FILL THE GAS TANK TO ABOUT THREE-QUARTERS FULL TO AVOID THE ODOR. SOME OWNERS SAID FUEL LEAKED FROM THE FUEL FILTER/SENDER, LOCATED ON THE TOP OF THE FUEL TANK ON THE DRIVER'S SIDE, AND COLLECTED ON TOP OF THE TANK. THIS IS A KNOWN ISSUE BUT THERE ARE OTHER MODELS AND YEAR MODELS THAT ARE AFFECTED AND DID NOT FALL UNDER THE MERCEDES RECALL CAMPAIGN.

WHILE MY CAR WAS RUNNING IN MY DRIVEWAY PRIOR TO DRIVING, THE ENGINE CAUGHT FIRE, TOTALING THE VEHICLE. THERE ARE NO OPEN RECALLS ON THIS SPECIFIC CAR, BUT WAS TOLD BY THE FIRE INVESTIGATOR THAT IT WAS EITHER ELECTRICAL OR FUEL PUMP RELATED. *TR
