MY FUEL TANK HAS DEVELOPED A LEAK WHERE I CAN SMELL FUEL BOTH OUTSIDE AND INSIDE THE VEHICLE AFTER FILLING THE TANK ALL THE WAY. THE ODOR IS VERY PRONOUNCED AND I AM CONCERNED ABOUT THE SAFETY OF THE VEHICLE IF THIS MUCH FUEL IS LEAKING FROM THE TANK. AN INDEPENDENT REPAIR SHOP CONFIRMED A LEAK FROM THE TOP OF THE FUEL TANK. BASED ON INFORMATION I READ ON A MERCEDES BENZ FORUM WEBSITE, IT SAID TO REFERENCE ACTION NUMBER PE12001 (THIS APPEARS TO BE A COMMON ISSUE WITH THIS SERIES OF VEHICLE). I HOPE THE NHTSA WILL INVESTIGATE THIS ISSUE AND FORCE MERCEDES BENZ TO REPLACE THESE DEFECTIVE AND UNSAFE FUEL TANKS AT NO COST TO CONSUMERS. *TR

THIS CAR DEVELOPED A VERY STRONG FUEL SMELL INSIDE THE CABIN SHORTLY AFTER FILLING UP WITH GAS IN EARLY 2012. I TOOK IT IN TO THE DEALER AND THEY DID WARRANTY WORK REPLACING SEALS, ETC. A LITTLE UNDER A YEAR LATER THE SMELL CAME BACK. AFTER DOING A LITTLE RESEARCH ONLINE I DECIDED TO TAKE A LOOK UNDER THE BACK SEAT AND FOUND WHERE GASOLINE HAS STAINED THE CUSHIONING AND A CLOTH THAT INSULATES BETWEEN THE FRAME AND THE SEAT. THE FUEL SMELL IS MUCH STRONGER IN THIS AREA, WHICH IS INSIDE THE CABIN. THE DEALER GAVE ME BACK AN ESTIMATE OF ALMOST $2,900 TO REPLACE THE ENTIRE FUEL TANK ASSEMBLY, SENDING UNITS, HOSES, ETC. THIS IS A KNOWN ISSUE WITH MBUSA. *TR

EVERY TIME I FILL THE GAS TANK THERE IS A STRONG SMELL OF GAS FUMES INSIDE AND OUTSIDE OF THE VEHICLE. IT IS NAUSEATING AND SEEMS WOULD BE DANGEROUS.THE DEALER STATES A TEST VERIFIED A LEAK AT THE LEFT PUMP HOUSING AREA. ADDITIONALLY FOUND STAINING AT THE TOP OF FUEL TANK NEAR CENTER MOUNTING AREA. THEY RECOMMENDED A REPLACEMENT OF THE FUEL TANK ASSEMBLY WITH NEW PUMP AND SENDING UNIT/FILTER ASSEMBLIES. THIS REPAIR IS $3000 US. THE PROBLEM IS THE NEW EQUIPMENT IS THE SAME FAULTY DESIGN OF THE ORIGINAL EQUIPMENT. MOST LIKELY THE SAME PROBLEM WILL OCCUR AGAIN. AFTER CHECKING OUT THE SITUATION I HAVE FOUND THIS IS A COMMON OCCURRENCE WITH THIS MAKE AND MODEL AND THAT THE MANUFACTURER IS AWARE OF THE PROBLEM. *TR

IF I FILL THE TANK FULL OF FUEL (NOT OVERFILLING), FUEL LEAKS FROM FUEL TANK, POOLS ON TOP OF TANK BY THE FUEL PUMPS UNDER THE REAR PASSENGER SEATS AND THE SMELL OF GAS INSIDE THE CAR IS OVERWHELMING.

AFTER CHECKING THE MERCEDES FORUMS, THIS ISSUE IS RAMPANT ON THE E CLASS MODELS, AND DESPITE REPLACEMENT OF NEW PARTS, THE PROBLEM REAPPEARS.

FILLED GAS TANK LATE IN THE EVENING, AND RETURNED HOME. CAR SAT OVERNIGHT AND HAD STRONG SMELL OF GASOLINE IN MORNING. OPENED ALL DOORS, LOOKED UNDERNEATH CAR AND FOUND NO FUEL LEAK. AIRED THE CAR FOR SEVERAL MINUTES AND THEN DROVE TO WORK. DURING THE ONE HOUR DRIVE, THE SMELL BEGAN TO GET WORSE. I OPENED WINDOWS PARTIALLY, BUT COULD NOT OPEN WIDE DUE TO RAIN. I DEVELOPED A HEADACHE BEFORE ARRIVAL. LEFT CAR PARKED AT WORK ALL DAY IN UNDERGROUND GARAGE. THE ODOR WAS AGAIN STRONG IN THE EVENING. I AIRED THE INTERIOR AS MUCH AS POSSIBLE BEFORE DRIVING HOME. AGAIN, AFTER NEARLY ONE HOUR, I DEVELOPED A HEADACHE AND FELT SQUEAMISH INSIDE THE CAR. I WAS ABLE TO STOP AND GET OUT OF THE VEHICLE FOR ABOUT 15 MINUTES TO REGAIN ALL SENSES SO THAT I COULD SAFELY DRIVE HOME. THE CAR NOW SITS IN MY GARAGE WITH THE BACK SEAT REMOVED TRYING TO GET THE SMELL OF GAS OUT OF THE VEHICLE. I HAVE NOW READ MANY OTHER SIMILAR COMPLAINTS FROM OTHERS WITH SAME MODEL VEHICLE. I REALIZE THERE ARE NOT TENS OF THOUSANDS OF THESE VEHICLES ON THE ROAD; I AM SURE THAT IF THERE WERE MORE VEHICLES WITH THIS PROBLEM THERE WOULD BE SEVERAL SEVERE ACCIDENTS. I TRY TO TAKE GOOD CARE OF MY VEHICLES AND THIS PROBLEM APPEARS TO BE THE FAULT OF THE MANUFACTURER OR PARTS SUPPLIER. THIS PROBLEM SHOULD NOT HAPPEN AND IT IS DANGEROUS. *TR

IM WRITING IN REFERENCE TO THE NHTSA ACTION # PE12001. I BOUGHT MY VEHICLE ON THE 23 OF DECEMBER 2012. I CAN HONESTLY SAY I FELL IN LOVE WITH THIS CAR. WITH THAT BEING SAID I HAVE NEVER FILLED THE FUEL TANK OF THIS CAR UNTIL 6-9-2013. THE REASON BEING I HAVE A 1998 FORD F150 THAT I DRIVE AS WELL. I MOSTLY DRIVE THE E55 ON WEEKENDS BUT ITS IN AND AROUND MY NEIGHBORHOOD. MY FATHER JUS CAME BACK FROM THE PHILIPPINES A COUPLE DAYS AGO SO HE NEEDS MY TRUCK TO GET AROUND WHILE HE'S VISITING. SO YESTERDAY I FOUND I NEEDED TO DRIVE THE E55 DAILY WHILE MY FATHER'S IN TOWN SO I FILLED UP THE TANK TO THE CAR. I PUT IN SHELL 91 AND WAITED FOR THE PUMP TO STOP. ONCE STOPPED I REMOVED FUELER AND INSERTED INTO ITS HOLSTER. NOTE I DID NOT TOP OFF FOR I NEVER FELT THE NEED TO IN ANY CAR I HAVE DRIVEN. I PROCEEDED STRAIGHT HOME AND PARKED CAR IN MY GARAGE, CLOSED THE GARAGE DOOR AND WENT IN THE HOUSE. THE E55 WAS IN THERE FOR THE REST OF THE DAY AND NIGHT. AND THEN THIS MORNING AS I WENT INTO GARAGE TO GO TO WORK I WAS JUS TAKEN BACK BY THE FUEL SMELL IN THE ENTIRE GARAGE. SO I OPENED THE GARAGE TO AIR OUT AND CHECKED UNDER THE CAR FOR A PUDDLE OF FUEL BUT FOUND NOTHING. THE SMELL IS MUCH STRONGER NEAR THE REAR OF THE CAR. I DROVE OFF EVEN WITH THE WINDOWS DOWN TO JUS RID THE SMELL AS IT ENTERED THE CABIN AS I STEPPED IN THE CAR TOO. NO PROBLEMS DRIVING TO WORK BUT AS I PARKED IN REVERSE I CAN SMELL FUEL AS THE WIND KICKED IT TOWARDS MY WINDOW. I PARKED AND GOT OUT AND SMELLED AROUND THE BACK AND STILL SMELLED FUEL. SO AS IM WORRIED THROUGHOUT THE DAY AT WORK I WENT INTO MY BENZWORLD FORUM AND FOUND ALOT OF THE SAME COMPLAINTS AS ME ESPECIALLY ON THE W211'S. SO AS I READ ON THE MORE WORRIED I GOT BECAUSE MY KIDS RIDE IN THIS CAR AND I DON'T WANT THEM AROUND IT ANYMORE ESPECIALLY WITH THIS PROBLEM GOIN ON. PLEASE HELP US WITH THIS PROBLEM. *TR

2EA13003 · Fuel Leakage From The Fuel Tank
Opened Mar 15, 2013 · Closed Dec 19, 2014
Status: closed (inferred from source dates) · Fuel System, Gasoline; Fuel System, Gasoline:delivery; Fuel System, Gasoline:delivery:fuel Pump; Fuel System, Gasoline:delivery:hoses, Lines/piping, And Fittings; Fuel System, Gasoline:storage; Fuel System, Gasoline:storage:tank Assembly
The Office of Defects Investigation (ODI) opened this investigation on January 23, 2012 as PE12-001 based on 20 consumer reports in model year (MY) 2003-2006 E55 AMG vehicles.Based on new reports in other E-Class vehicles, ODI upgraded the investigation to Engineering Analysis (EA) 13-003 on March 15, 2013, and expanded the scope to all E-Class vehicles through MY 2008.The complainants alleged a strong odor of gasoline fuel both inside and outside of their vehicle, particularly after refilling the fuel tank.Many of the complainants noted that the odor subsided or went away after driving some distance thereby lowering the fuel level in the tank.Other owners reported they would only fill the tank to about three quarters full to avoid the odor altogether.Some complainants alleged 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.There were also allegations that the fuel leaks were associated with an Emissions Recall Campaign (No. 2008020001) conducted by Mercedes-Benz USA, LLC (Mercedes) in 2008 on MY 2003-2006 E-Class and CLS-Class AMG models.The issue in the recall involved small cracks in the pressurized outlet fitting of the fuel filter/sender.AMG vehicles are high performance models that operate at higher fuel pressure and use a different fuel filter/sender and fuel pump than non-AMG models.Information on Recall No. 2008020001 is available from the U.S. Environmental Protection Agency (EPA) website at www.EPA.gov.ODI's investigation found various leak sources that are unrelated to the outlet fitting cited in the EPA recall campaign.Through interviews with complainants, field inspections of complaint vehicles, and the collection and laboratory analysis of failed parts, three identifiable leak sources were found.The component parts and areas of the leaks involve the On-Board Diagnostic fuel tank pressure sensor (located on top of the fuel filter/sender), the outlet of the centrally mounted fuel tank fuel filling limiter valve, and the top of the fuel pump. These areas of leakage are located at the top of the fuel tank in unpressurized parts of the fuel system. When the tank is full, fuel can slowly weep/seep from micro-cracks in these components and may collect in cavities on top of the filter/sender, pump, or tank.Contrary to complainant's allegations that fuel entered the inside of their vehicle under the rear seat bench, neither ODI nor Mercedes found a plausible way for this to occur.The fuel tank is located outside of the passenger compartment, attached to the underside of the vehicle.The service access ports for the fuel filter/sender (driver's side) and fuel pump (passenger's side) are located under the rear seat bench, covered by a steel plate, sealed and bolted to the vehicle floor.When technicians service the fuel filter/sender, which has a regularly scheduled 60,000 mile service interval, and/or the fuel pump, the work is performed from inside the vehicle by working through the access ports.By letter dated September 4, 2014, Mercedes has notified the agency that it will extend the original warranty coverage to 15 years and unlimited mileage on Covered Fuel Tank Components in E-Class vehicles in MY 2003-2009 and CLS-Class vehicles in MY 2006-2011.The covered fuel tank components for the warranty extension include the fuel tank, fuel filter/sender, fuel pump, and all related gaskets/seals and retention rings.ODI is closing this investigation based on the manufacturer's extend warranty of the affected fuel system components and in consideration that the nature of the leaks does not appear to present an un

When the tank is full, fuel can slowly weep/seep from micro-cracks in these components and may collect in cavities on top of the filter/sender, pump, or tank.Contrary to complainant's allegations that fuel entered the inside of their vehicle under the rear seat bench, neither ODI nor Mercedes found a plausible way for this to occur.The fuel tank is located outside of the passenger compartment, attached to the underside of the vehicle.The service access ports for the fuel filter/sender (driver's side) and fuel pump (passenger's side) are located under the rear seat bench, covered by a steel plate, sealed and bolted to the vehicle floor.When technicians service the fuel filter/sender, which has a regularly scheduled 60,000 mile service interval, and/or the fuel pump, the work is performed from inside the vehicle by working through the access ports.By letter dated September 4, 2014, Mercedes has notified the agency that it will extend the original warranty coverage to 15 years and unlimited mileage on Covered Fuel Tank Components in E-Class vehicles in MY 2003-2009 and CLS-Class vehicles in MY 2006-2011.The covered fuel tank components for the warranty extension include the fuel tank, fuel filter/sender, fuel pump, and all related gaskets/seals and retention rings.ODI is closing this investigation based on the manufacturer's extend warranty of the affected fuel system components and in consideration that the nature of the leaks does not appear to present an un
