FUEL IS LEAKING FROM THE SENDING UNIT OF THE VEHICLE AND DOWN ONTO THE REAR WHEELS DIFFERENTIAL, THE VEHICLES FUEL TANK AND SENDER UNIT HAD BEEN REPLACED BY MERCEDES UNDER WARRANTY ON 11/25/03 MILEAGE IN 43088 MILEAGE OUT 43092 AT THE HOEHN CARLSBAD CA DEALER SHIP: INVOICE NUMBER 465553. THIS HAS NOW HAPPENED AGAIN AND I HAVE FOUND THAT THIS ISSUE IS NOT A LIMITED ISSUE TO MY VEHICLE BUT ONE THAT HAS IMPACTED ALL C CLASS AND E CLASS VEHICLES AND HAS AN ESTIMATED REPAIR COST OF $2,073.30. HOW IS DAIMLER AG ALLOWED TO SELL THESE VEHICLES THAT POSE AN EXTREME RICK THE PUBLIC AND PROPERTY IN THE US. I HAVE BEEN TOLD MY VEHICLE IS NOW NO LONGER COVERED UNDER ANY WARRANTY AND I WILL HAVE TO FOOT THE BILL TO REPAIR THIS OBVIOUS DESIGN FLOOR AND SUBSEQUENT MALFUNCTION THAT POSSES A LIFE THREATENING RISK TO ME AND MY FAMILY IF NOT RESOLVED ASAP. I DREAD TO THINK ABOUT ALL THE PRESENT MERCEDES C-CLASS AND E-CLASS OWNERS DRIVING AROUND IN A TICKING TIME BOMB JUST WAITING TO GO OFF, THERE MUST BE HUNDREDS OF THOUSANDS OF VEHICLES THAT HAVE DEFECTIVE FUEL SENDING UNITS/GAS TANKS LEAKING GAS DOWN AND AROUND HOT EXHAUST PIPES OF THEIR VEHICLES AND THEY ARE NOT AWARE OF THIS PERENNIALLY LIFE THREATENING MALFUNCTION BECAUSE DAIMLER AG HAS NOT RECALLED ALL VEHICLES OUTFITTED WITH RECOGNIZED DEFECTIVE FUEL SENDING UNITS/GAS TANKS AND RESOLVED THE TICKING TIME BOMBS. IT'S OBVIOUS TO ME WHATEVER ATTEMPT DAIMLER AG HAS TAKEN IS NOT ENOUGH TO MITIGATE ANY FURTHER DEFECTIVE FUEL SENDING UNITS/GAS TANKS. PLEASE ADVISE ON ANY WHETHER WE HAVE ANY RE-CAUSE WITH DAIMLER AG OR MERCEDES U.S.A TO GET THIS FRIGHTENING ISSUE RESOLVED FOR NOT ONLY ME BUT ALSO THE HUNDREDS OF THOUSANDS OF AMERICAN MOTORIST PRESENTLY DRIVING TICKING BOMBS. YOU MAY CONTACT ME ON DAYTIME PHONE NUMBER TO DISCUSS THIS ISSUE. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THE FUEL TANK ON MY 2003 C32 LEAKED. THE SYMPTOM WAS A STRONG GAS ODOR INSIDE THE VEHICLE. UPON FURTHER INSPECTION, THERE WAS FUEL LEAKING FROM UNDER THE VEHICLE. I TOOK IT TO THE MECHANIC, AND HE DIAGNOSED IT AS A LEAKING FUEL TANK. WHEN HE REMOVED IT, HE SHOWED IT TO ME AND I SAW THE PART THAT WAS CRACKED, WHICH WAS BELOW THE REAR SEAT OF THE CAR. THERE APPEARS TO BE A WIDELY KNOWN MALFUNCTION WITH FUEL TANKS FOR MERCEDES. THIS WAS A VERY STRESSFUL EVENT, ESPECIALLY WITH FUEL LEAKING OUTSIDE THE CAR AND NOT KNOWING WHAT COULD HAPPEN (FIRE RISK, ETC). *TR

I PURCHASE MY 2003 MERCEDES FROM CARMAX IN 2 YEARS AGO. IT HAD 45,000 MILES WHEN I PURCHASED IT. FROM THE TIME I PURCHASE THIS CAR I HAD TO REPLACE THE SUNROOF MOTOR, REPLACE THE SHOCKS, REPLACE THE TRUCK LOCK, REPLACE THE FUEL TANK, AND I HAD SOME TRANSMISSION WORK DONE. MY BIGGEST PROBLEM IS HAVING TO REPLACE THE LOW BEAM LIGHTS EVERY 6 MONTHS. I SUSPECT THERE IS AN ELECTRICAL PROBLEM, BUT CANNOT COMPLETELY PROVE IT WITH THE MANUFACTURER. WITH 1 YEAR, I HAD TO REPLACE THE BULBS 3 TIMES. I HAD TO REPLACE THE FRONT LOW BEAM BULBS AND THE BRAKE LIGHTS. THIS IS SURPRISING SINCE THIS CAR (UNDER MY OWNERSHIP) HAS NEVER BEEN IN AN ACCIDENT. I AM SO DISAPPOINTED I PURCHASED THIS CAR! *TR

DT: THE CONTACT STATES THE AIRBAG SYSTEM FAILED TWICE IN THE PAST TEN MONTHS. THE ONBOARD COMPUTER SAID SRS WARNING DID NOT DRIVE AT THAT TIME,. THE VEHICLE HAD TO BE TOWED TO THE DEALERSHIP. THERE WAS A CODE RESET IN THE COMPUTER. THIS HAPPENED AGAIN, AND THEY REPLACED A FUSE BOX IN THE DASHBOARD. THE GAS GAUGE HAS ALSO GONE OUT TWICE IN ONE MONTH. THE DEALERSHIP DRAINED THE GAS AND RESET A COMPUTER CODE. WHEN IT HAPPENED AGAIN THEY HAD TO REPLACE A PART IN THE GAS TANK AND RESET THE COMPUTER CODE AGAIN. BOTH ITEMS WERE WORKING CORRECTLY AT THIS TIME.*AK

VEHILE IS AN AUTOMATIC. VEHICLE "JERKS" HARD WHEN LIGHTLY APPLYING GAS. THIS CAN BE COMPARED TO STARTING IN FIRST GEAR (MANUAL TRANSMISSION) WHEN NOT FULLY DEPRESSING THE CORRECT COMBINATION OF GAS AND CLUTCH. THIS HAPPENS WHEN TRAVELING FROM A DEAD STOP AT A TRAFFIC LIGHT OR PULLING INTO A PARKING SPACE. HAVE HAD SEVERAL NEAR MISSES IN HITTING OTHER VEHICLES.*AK
