2007 MERCEDES BENZ AMG E63 Fuel System, Gasoline Problems

THERE IS A STRONG SMELL OF GASOLINE OVER 1/2 TANK FULL, AND FREQUENT CHECK ENGINE LIGHTS ON FOR AN EVAP SYSTEM LEAK. THIS IS A KNOWN ISSUE WITH THESE CARS, AND I AM CONCERNED TO DRIVE THE VEHICLE WITH GASOLINE FUMES COMING INSIDE THE CAR AND CREATING A FIRE HAZARD. MERCEDES KNOWS ABOUT THIS PROBLEM AND NEEDS TO ADDRESS IT. *TR

I PURCHASED THIS CAR LATE JULY 2012 AND WHEN I WENT TO PICK IT UP I NOTICED A SLIGHT SMELL OF GAS FROM THE LEFT REAR OF CAR BUT, DIDN'T THINK MUCH OF IT AS IT WAS A NEW TO ME VEHICLE, JUST THOUGHT IT WAS FRESHLY FILLED UP. THE NEXT TIME I FILLED UP I NOTICED THAT THE CAR SMELLED BOTH INSIDE THE CAR AND OUTSIDE THE CAR. AS A NEW OWNER OF A NEWER MB I JOINED MBWORLD FORM AND SEARCHED THIS PROBLEM WITH E55 AND E63 AND FOUND THAT IT IS A COMMON PROBLEM FOR THE W211 CARS. ALSO, IT SEEMS THE SOLUTION IS NOT AS OBVIOUS AS ONE WOULD THINK. ON NOV 14, 20012 I TOOK IT TO CAL STAR MOTORS IN GLENDALE CA (A MERCEDES DEALER) FOR REPAIR, THEY TOLD ME THAT THE CAUSE OF THE PROBLEM IS THE SEAL BETWEEN THE SENDING UNIT AND THE GAS TANK. THEY REPLACED THIS PART AND I DROVE THE CAR HOME AS I NEEDED TO BRING IN CAR WITH HALF A TANK FOR REPAIR I DID NOT NOTICE ANY ISSUE. NEXT TIME I FILLED UP THERE WAS NO SMELL FROM INSIDE CABIN AND ONLY SLIGHT SMELL OUTSIDE. I NOW HAVE FILLED UP SEVERAL TIMES AND THE PROBLEM HAS RETURNED. I SHOULD SAY THAT AFTER FILL UP THERE HAS NEVER BEEN ANY LEAKED GAS PRESENT WHEN PARKED AS I CHECK DRIVE DAILY FOR ANY EVIDENCE OF LEAKS IN ANY FLUID. I FEEL THAT IF THERE IS A GAS LEAK ISSUE WITH THIS/THESE CARS WHICH IT APPEARS THERE IS BASED ON SO MANY ISSUES REPORTED THAT MERCEDES HAS A RESPONSIBILITY TO SOLVE THE PROBLEM AS IT IS A VERY DANGEROUS SITUATION TO LEAVE UNRESOLVED. *TR

NOTICE A GAS SMELL AFTER FILLING UP THE TANK. DID NOT REALLY TOOK IT FOR ANYTHING BUT ON THE SECOND FILL SMELL AGAIN INSIDE THE CAR. BEING SUMMER I DRIVE WINDOWS DOWN AND SMELL WAS NOT BAD UNTIL I HAD THE AC ON. ONLINE RESEARCH PROVE IT TO BE THE TANK. AND ITS A KNOWN DEFECT BUT MB WILL NOT FIX IT. MORE I CHECK INTO THE PROBLEM ITS AN ON GOING ISSUE WITH THESE CARS. 100K AND NO ONE WILL LISTEN TO YOUR ISSUES. I NOW FILL 3/4 AS THE FIX AND NO ISSUES AND CAN NOT SELL IT TO SOMEONE ELSE KNOWING THIS IS A PROBLEM. *TR

FILLED AUTO WITH FUEL FOR FIRST TIME AND DROVE HOME, PARKED IN THE GARAGE AND STARTED TO SMELL GAS FUMES FROM DRIVER'S SIDE PASSENGER SEAT AREA. LEARNED THAT THERE IS NHTSA ACTION NUMBER: PE12001 PERTAINING TO E55 WHICH WAS PREVIOUS YEAR MODEL TO MINE. THREAT OF FIRE UNDER WHERE MY CHILD SITS IS UNACCEPTABLE. MY EARLY MODEL E63 WITH SAME FUEL ISSUES SHOULD BE COVERED. PLEASE COVER THIS MODEL AND MODEL YEAR AS WELL! *TR

FILLED MY CAR UP WITH GAS AND AFTER DRIVING IT HOME THERE IS A VERY STRONG FUEL SMELL COMING FROM THE CAR. LOOKING ONLINE I SEE THAT MANY PEOPLE WITH THE E63 AMG CARS HAVE ALSO EXPERIENCED THIS, AND IT IS A FAULTY FUEL SENDER UNIT THAT IS LITERALLY LEAKING FUEL OUT. *TR

I REPORTED TO MY INDEPENDENT MECHANIC A STRONG FUEL SMELL WHEN FILLING THE VEHICLE FULL AND PARKING IT. UPON FURTHER INVESTIGATION, MY MECHANIC DISCOVERED A FUEL LEAK FROM THE DRIVERS SIDE OF THE TANK ONTO THE LEFT EXHAUST WHICH OF COURSE CAN CREATE A FIRE HAZARD. I IMMEDIATELY CONTACTED MY LOCAL MB DEALERSHIP AND SPENT DAYS TRYING TO GET IN TOUCH WITH THE SERVICE MANAGER. FINALLY AFTER CONTACTING THE MB CENTRAL REGION OFFICE, I LEFT A VM AND WAS CONTACTED BY THE SERVICE MANAGER I HAD BEEN TRYING TO GET IN TOUCH WITH. AS OF TODAY 4/8/13, I TOOK THE VEHICLE IN FOR INSPECTION. THEY TOLD ME THAT THE DRIVERS SIDE FUEL SENDING UNIT/PUMP IS LEAKING AND WOULD NEED TO BE REPLACED. I ASKED IF THE CAR WAS SAFE TO DRIVE, THEY REPLIED NO, BUT HAPPILY SENT ME ON MY WAY ANYHOW. THIS PROBLEM LINES UP WITH EVERY OTHER COMPLAINT ABOUT THE MY03-09 W211'S THAT EXHIBIT THIS PROBLEM. I HAVE NOT HAD THE FUEL LEAKING TO THE GROUND AND POOLING UP, BUT THE DEALERSHIP HAS CONFIRMED THAT THE SENDING UNIT IS INDEED LEAKING AND POOLING UP IN THE DEPRESSION WHERE THE SENDING UNIT ATTACHES TO THE TANK, WHICH IS NOW LEAKING ONTO MY DRIVERS SIDE EXHAUST, THUS CREATING POTENTIAL FOR A FIRE HAZARD. NHTSA ACTION NUMBER: EA13003. *TR

GAS SMELL IN THE MY GARAGE AND STRONG INSIDE CABIN AFTER FILLING THE CAR UP. CHECKED UNDER SEAT AND PUDDLE ON TOP OF FUEL PUMP AREA. CLEANED UP FUEL AND CONSULTED INTERNET FOR DIAGNOSE OF ISSUE. FOUND THIS WAS A COMMON PROBLEM AND FOUND SOME TO GET FIXED WITH PUMP REPLACEMENT OR WHOLE TANK REPLACEMENT. TOOK IN TO DEALER AND THEY SAID IT WAS THE PUMP AND WANTED $800 TO FIX. PER INTERNET OPTED NOT TO PAY FOR REPLACEMENT AND HAVE LEFT AS IS JUST NOT FILLING CAR UP WITH FUEL. ONLY FILL TO 3/4 TANK AND NO SMELL SINCE. *TR
