AFTER REFUELING VEHICLE, I NOTICED A STRONG ODOR OF RAW GASOLINE IN THE INTERIOR OF THE VEHICLE EMANATING FROM THE REAR SEAT AREA. IN JULY, 2011, A MERCEDES DEALERSHIP DETERMINED TWO SENDING UNITS LOCATED UNDER THE REAR SEAT WERE LEAKING, NECESSITATING THEIR REPLACEMENT. THE CAR WAS OUT OF WARRANTY AND THERE WAS NO MENTION OF ANY RECALL OR SERVICE CAMPAIGN RELATIVE TO THE DEFECTIVE PARTS. THE APPROXIMATE COST TO ME WAS $2000.00. JUST LAST WEEK, ON APRIL 6, 2012 THE SAME EVENT OCCURRED WHEREIN I REFUELED THE VEHICLE AND, AGAIN, NOTICED THE SAME GAS ODOR. THIS TIME I ALSO NOTICED FUEL HAD SPILLED ON THE PAVEMENT IN THE VICINITY OF THE RIGHT REAR PORTION OF THE UNDERSIDE OF THE VEHICLE. THE VEHICLE WAS RETURNED TO THE DEALER THAT MADE THE ORIGINAL REPAIRS AND I AM AWAITING THEIR ASSESSMENT OF THE PROBLEM. THIS RECURRENCE HAPPENED JUST NINE MONTHS AND 6,000 MILES AFTER THE PREVIOUS REPAIR. IN THE INTERIM, I BECAME AWARE OF A 2008 RECALL INVOLVING A FUEL LEAK ON MY MODEL VEHICLE. I HAVE ASKED THE DEALER TO DETERMINE IF THE JULY, 2011 REPAIR SHOULD HAVE, IN FACT, BEEN COVERED BY THE RECALL CAMPAIGN. I HAVE ALSO SINCE LEARNED THAT NUMEROUS OWNERS OF MY TYPE VEHICLE HAVE EXPERIENCED SIMILAR GAS LEAKS LEADING ME TO BELIEVE THIS IS A WIDESPREAD, FREQUENT PROBLEM WHICH HAS SERIOUS RAMIFICATIONS REGARDING PERSONAL SAFETY AND ENVIRONMENTAL PROTECTION. MY COMPLAINT IS THAT THE MANUFACTURER APPEARS TO HAVE IMPROPERLY DESIGNED A PART OR SERIES OF PARTS THAT EITHER ALONE OR IN COMBINATION FAIL RESULTING IN A HAZARDOUS FUEL LEAK. GIVEN THE RECURRENCE OF THE LEAK IN MY CASE IN SUCH A SHORT PERIOD OF TIME, IT APPEARS THE REMEDIAL ACTION IS INEFFECTIVE IN SOLVING THE GAS LEAK PROBLEM. *TR

AFTER FILLING THE CAR UP THERE WAS A STRONG GAS SMELL INSIDE THE CABIN OF THE CAR. IT WAS SO STRONG THAT WE HAD TO ROLL THE WINDOWS DOWN TO HELP THE SMELL GO AWAY BUT IT WAS STILL VERY STRONG. AFTER DRIVING HOME AND PARKING THE CAR (2 MILE TRIP HOME) THERE WAS A SMALL PUDDLE OF GAS ON THE DRIVEWAY FLOOR ABOUT 2-3 HOURS AFTER PARKING THE CAR. I HAD THE CAR TOWED TO AN INDEPENDENT REPAIR FACILITY AND WAS TOLD THE THERE WAS GAS COMING FROM THE TOP OF THE PASSENGER SIDE FUEL PUMP AND THAT IT WAS A COMMON PROBLEM. THEY REPLACE THE O-RING AND A COUPLE OF FUEL LINES AND SAID THAT I MAY NEED TO HAVE THE ENTIRE FUEL TANK,PUMPS AND 2 OF THE FUEL LINES REPLACED IF IT HAPPENS AGAIN. I CALLED THE DEALERSHIP AND WAS TOLD THEY KNOW THIS IS AN ONGOING PROBLEM BUT THERE IS NO RECALL AND I WOULD BE RESPONSIBLE OUT OF POCKET AND THE COST WOULD BE $2500-$3000. HOW IS A FUEL LEAK THAT IS OBVIOUSLY A DEFECT FROM MERCEDES AND HAS AFFECTED 1000'S OF VEHICLES NOT A RECALL? I DID A LOT OF RESEARCH ON THIS AND HAVE FOUND MANY CLAIMS OF THIS ON MERCEDES FORUM'S SO THIS ISN'T AN ISOLATED INCIDENT. *TR

FUEL TANK LEAKS FUEL ONTO THE GROUND VIA THE EXTERNAL INTER TANK TRANSFER HOSE ON THE TOP OF THE TANK. TO REPAIR THIS MERCEDES HAS TO REPLACE THE TANK WHICH REQUIRES A COMPLETE TEARDOWN OF THE REAR SUSPENSION AND REAR SUBFRAME. I BROUGHT THE CAR TO THE DEALER FOR THIS ISSUE 5 TIMES, ANY TIME THE TANK WAS GREATER THAN HALF FULL IT WOULD LEAK A SIGNIFICANT (A PUDDLE FORMED) AMOUNT OF FUEL ON THE GROUND. MERCEDES BENZ DID NOT WARRANTY THIS ISSUE STATING THAT THEY HAVE NEVER SEEN THIS ISSUE AND IT WAS A ONE TIME THING, EVEN THOUGH THEY "REPAIRED" IT FIVE TIMES. *TR

MY 2004 E55 AMG WAS PARKED IN THE GARAGE AFTER DRIVING HOME FROM WORK. WHEN RETURNING TO THE GARAGE ABOUT 45 MINUTES LATER I IMMEDIATELY NOTICED THE GARAGE WAS CONSUMED WITH GAS FUMES. I BACKED THE CAR OUT OF THE GARAGE ONLY TO FIND THAT A 1/4 TANK OR SO OF GAS HAD SPILLED ON THE FLOOR. HESITANT TO LEAVE THE CAR IN THE GARAGE OVERNIGHT, I DROVE THE CAR 10 MINUTES DOWN THE ROAD TO MY LOCAL MERCEDES-BENZ DEALER FOR INSPECTION. (I THOUGHT IT BEST NOT TO WAIT UNTIL MORNING, AS HOT EXHAUST PIPE AND GAS SPILL WAS NOT SOMETHING I AM COMFORTABLE WITH.) I FOUND THAT MANY VEHICLES HAVE EXPERIENCED THIS ISSUE AND THIS IS NOT UNCOMMON OF MY MAKE AND MODEL VEHICLE. AFTER READING MANY SAFETY CONCERNS AND EVEN HAVING MY OWN CONCERNS NOW OF DRIVING THE CAR, I DECIDED TO WRITE THIS FORMAL COMPLAINT. EVEN AFTER THE REPAIR, THE CAR SMELLS OF GASOLINE INSIDE AND OUTSIDE. STILL HESITANT TO PARK IN THE GARAGE, I AM KEEPING THE CAR OUTSIDE UNTIL IT HAS BEEN DETERMINED SAFE. *TR

I HAVE A 2004 MERCEDES AMG E55. I PURCHASED THE CAR SECOND HAND FROM MY NEIGHBOR AT +/-33,000 MILES. ONE WEEK OF OWNERSHIP, I GOT A CHECK ENGINE LIGHT. I HAD ACCESS TO A OBD2 SCANNER AND GOT THE CODE FOR EVAP ERROR. I STORED THE CAR OVERNIGHT IN MY GARAGE AND WOKE UP THE FOLLOWING MORNING WHERE THE WHOLE HOUSE REEKED OF FUEL. I HAD RECENTLY FILLED UP THE NIGHT BEFORE. BEING FAMILIAR WITH THIS MERCEDES VEHICLE I WENT OVER THE FUEL SYSTEM FROM GAS SPOUT TO GAS TANK. THE SMELL WAS COMING FROM INSIDE THE CAR UNDER THE REAR DRIVERS SIDE PASSENGER SEAT. UPON FURTHER INSPECTION AND REMOVAL OF THE SEAT,ACCESS PANEL. I COULD SEE GASOLINE PUDDLING UP ON TOP OF THE FUEL SENDER. I GOT SOME PAPER TOWELS AND DRIED IT. THAT MORNING I BOUGHT A NEW GASKET SEAL FROM THE DEALER TO TRY AND ISOLATE THE PROBLEM. THAT DID NOT HELP...NEXT GAS FILL UP THE CAR CONTINUE TO SMELL LIKE FUEL INSIDE THE CABIN. I TOOK IT TO A INDEPENDENT MECHANIC WHO PERFORMED THE SMOKE TEST TO SEE WHERE THE LEAK IS COMING FROM AND SURE ENOUGH IT WAS FROM THE TOP OF THE GAS TANK WHERE IT MET THE FUEL SENDER. UPON TAKING THE CAR TO THE DEALER, I'VE BEEN TOLD I HAVE TO REPLACE THE ENTIRE GAS TANK, FUEL PUMP, FUEL SENDER AND FITTINGS TO FIX THIS PROBLEM. THE DEALER WANTS ME TO PAY OUT OF POCKET THE ENTIRE COST WHICH IS ABOUT $3,000. THERE STILL IS A EMISSIONS WARRANTY ON THE CAR WHICH IS GOOD UP TO 8 YEARS OR 80,000 MILES WHICH THEY WILL NOT HONOR AS THEY FEEL THIS ISSUE DOESN'T QUALIFY. THEY HAVE JUST LAUGHED AT THE SITUATION AND TRIED TO DOWNPLAY IT. A LOT OF CUSTOMERS HAVE BEEN FORCED TO PAY OUT OF POCKET TO COVER THIS REPAIR AS THEY TRANSPORT THEIR KIDS IN THIS CAR AND THAT IS VERY IMPORTANT. TO PREVENT ANY FURTHER LEAKING, I ONLY FILL MY CAR WITH GAS HALFWAY AND HAVE RESET THE CHECK ENGINE LIGHT WITH MY SCANNER. THANK YOU. *TR

2EA13003 · Fuel Leakage From The Fuel Tank
Opened Mar 15, 2013 · Closed Dec 19, 2014

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
