2007 MERCEDES BENZ E550 Fuel/propulsion System Problems

When I filled up gas and start the car, it has gas smell. seems like fuel is pooling on the left side on top of the fule filter module underneath the cushion. Searched the internet and found out it is a common problem on Mercedes.

CAR SMELLS LIKE GAS INSIDE AND OUT UNTIL ABOUT HALF A TANK AFTER REVIEWING MERCEDES BENZ FORMS IN THE BENZ WORLD WEBSITE IT IS A VERY COMMON PROBLEM WITH THE E500 AND E550 IN THE YEARS BETWEEN 2005 AND 2008 VEHICLES THERE ARE NUMEROUS COMPLAINTS ABOUT IT AND NOT SURE WHEN IT STARTED I'VE JUST RECENTLY PURCHASED THE VEHICLE BUT THE PREVIOUS OWNER PREVIOUS OWNER MENTIONED IT TO ME AS WELL I DIDN'T THANK TO MUCH ABOUT IT TILL THE SMELL HAS GOTTEN SO BAD THAT THE WINDOWS HAVE TO BE ROLLED DOWN TO BE ABLE TO BREATHE IN THE VEHICLE

AFTER FILLING UP THE FUEL TANK THERE IS A STRONG ODOR OF GASOLINE. I SMELLS INSIDE AND OUTSIDE OF THE CAR UNTIL THE CAR REACHES THREE QUARTERS OF A TANK OR LESS. I HAVE READ IN THE MERCEDES BENZ FORUMS THAT ALOT OF PEOPLE ARE HAVING PROBLEMS WITH THIS! I AM DRIVING A TICKING TIME BOMB.

I JUST NOTICED A VERY POTENT GAS ODOR ON THE REAR BOTH RIGHT AND LEFT SIDE OF THE CAR. THERE ARE NO LEAKS ON THE GARAGE FLOOR OR MY DRIVEWAY. I KNOW THERE WAS A RECALL FOR THE 2003-2006 E-CLASS, BUT WAS THERE ONE FOR 2007-2009 MODELS AS WELL? I JUST NOTICED IT TODAY AND I AM THE 2ND OWNER OF THE VEHICLE, CAR HAS ABOUT 78K ON THE ODOMETER.

SMELL STRONG GASOLINE EVERY I FILL UP THE GAS TANK.

GAS LEAKING FROM REAR AREA OF VEHICLE; STRONG FUEL ODOR AFTER REFUELING. *TR

STRONG GAS VAPORS AND POSSIBLE FUEL LEAKAGE. GAS VAPORS ARE REALLY STRONG WHEN VEHICLE IS PARKED IN GARAGE IMMEDIATELY. THE GAS VAPORS CAN BE SMELLED WHILE DRIVING CAUSING THE FUMES TO BE INHALED AND DIZZINESS. THIS CAN NOT BE SAFE. *TR

EVERY TIME CAR IS FILLED WITH GAS, THERE IS AN OVERPOWERING GAS SMELL IN THE CAR AND THE GARAGE. TOOK VEHICLE TO LOCAL MERCEDES BENZ DEALERSHIP. DEALERSHIP FOUND FUEL TANK LEAKING FROM TOP OF FUEL TANK ABOVE SENDER. CHARGED MY FATHER $3,293.15 FOR REPAIR. THIS IS OBVIOUSLY A MANUFACTURERS DEFECT. *TR

PURCHASED VEHICLE NOV 2012, FILLED CAR UP FOR THE FIRST TIME 3/20/13 FOR OUT OF TOWN TRIP. NOTICED VERY STRONG GAS ODOR IN BACK SEAT. DID NOT RE-FILL WHILE OUT OF TOWN DUE TO POSSIBLE LEAKING FUEL SENDING UNIT AND/OR GAS TANK. *TR

I HAVE HAD TWO EARLIER ATTEMPTS IN 2011 TO FIX A STRONG GASOLINE SMELL FROM MY MERCEDES BENZ E550 2007 DID NOT FULLY RESOLVE THE PROBLEM. FINALLY, IN OCTOBER OF 2012 (APPROX. 10/10/12) MERCEDES BENZ DID REPLACE UNDER WARRANTY THE ENTIRE GASOLINE TANK AND RELATED LINES AND CONNECTION. THIS DID RESOLVE THE PROBLEM OF GASOLINE SMELL IN MY GARAGE AFTER GASOLINE TANK FILL-UP. NO GAS LEAKS EVER NOTICED OR FIRE EVER OCCUR. THANKS VERY MUCH FOR YOUR EFFORTS TO INFORM AND PROTECT CONSUMERS OF MERCEDES BENZ E550 2007. *TR

AFTER FILLING UP MY FUEL TANK COMPLETELY FULL, I FOUND THAT AFTER HAVING MY CAR IN THE GARAGE FOR A FEW HOURS IT HAD A NOTICEABLE ODOR OF GASOLINE BOTH IN THE GARAGE AND INSIDE THE VEHICLE. THIS HAS OCCURRED SINCE MY OWNERSHIP OF THE VEHICLE BEGAN IN MARCH 2012 AND IS STILL AN ISSUE ONE YEAR LATER. UPON FURTHER RESEARCH RECENTLY ON MBWORLD.ORG, I FOUND OUT THAT THIS WAS DUE TO A FAULTY "FUEL SENDER" ASSEMBLY THAT WAS CAUSING GASOLINE TO LEAK AND POSSIBLY POOL ON TOP OF THE TANK. WHILE THERE ARE NO VISIBLE LEAKS, I AM QUITE CONCERNED ABOUT THE GASOLINE VAPORS, AS THIS IS A KNOWN ISSUE ON THE W211 VEHICLE AND MERCEDES-BENZ HAS THUS FAR REFUSED TO PAY FOR ANY REPAIRS TO MAKE MY VEHICLE SAFE AGAIN.
