THE FUEL SENSOR FAILED, RESULTING IF FUEL LEAKS. THERE ARE MANY REPORTS AND MERCEDES DENIES THE PROBLEM. AMAZING THAT SUCH A BIG SAFETY ISSUE IS BEING IGNORED AND DENIED BY MERCEDES. THIS IS SO PREVALENT, IN A PRETTY RARE CAR, THAT MY DEALER STOCKS THE REPAIR PARTS. EVEN MY SERVICE ADVISER WAS SURPRISED THEY DID. IN READING MERCEDES' RESPONSE TO THE INVESTIGATION, IT IS ALMOST A JOKE. THEY CLAIM THAT SINCE THIS ISN'T DIRECTLY RELATED TO THE RECALL, THERE ISN'T AN ISSUE. THAT MAKE ABSOLUTELY NO SENSE. PERHAPS IT ISN'T RELATED TO THE RECALL, BUT YOU HAVE 50+ COMPLAINTS FOR A CAR WHERE AROUND 1,500 WERE IMPORTED. ESTIMATING 1 IN 10 PEOPLE ACTUALLY COMPLAIN THAT MEANS THAT 1/3 OF THE CARS HAVE THE PROBLEM. IF IT IS 1 IN 20, THAN 2/3RDS HAVE THE PROBLEM. AT $1000+ TO FIX, MERCEDES IS MAKING A TON OF MONEY ON THEIR FAILURE. *TR

NOTICED A GAS SMELL OUTSIDE OF THE CAR WHEN IT WAS SITTING STILL AND I LOOKED UNDER THE CAR AND FUEL HAD PUDDLES UP UNDER IT. OPENED THE DOORS AND NOTICED A STRONG FUEL SMELL INSIDE THE CAR. PULLED OUT THE REAR SEATS AND LIFTED UP THE LINER UNDER THE SEATS AND NOTICED FUEL WAS POOLED UP IN THE PASSENGER SIDE BOWL UNDER THE SEAT. THE SEAL THAT IS BOLTED DOWN HAS PUSHED OUT AND IS ALLOWING FUEL TO COME INSIDE THE CAR AND HAS SOAKED INTO THE LINER UNDER THE SEAT. ALSO THE BOLT THAT HOLDS DOWN THE SENDING UNIT WILL NOT SCREW INTO THE HOLE DUE TO THE BOLT HOLE BEING STRIPPED OUT.

STRONG FUEL ODOR INSIDE AND OUTSIDE OF CABIN. OUTSIDE SMELL IS STRONG AT REAR PASSENGER SIDE OF CAR. CANNOT LEAVE CAR INSIDE OF MY GARAGE BECAUSE OF THE STRONG FUEL ODOR. (ESPECIALLY IF FUEL IS OVER 1/4 TANK) NO VISIBLE LEAKING OF FUEL ON FLOOR. AFTER SPEAKING WITH OTHER MERCEDES E55 OWNERS, MANY APPEAR TO HAVE THE SAME ISSUE. I HAVE A SMALL AMOUNT OF FUEL SITTING ON TOP OF SENDER UNITS UNDER THE REAR PASSENGER SEAT. I HAVE A NEWBORN BABY THAT I CANNOT TRANSPORT IN THIS CAR DUE TO THE FUMES.

IN DECEMBER 2011 I DETECTED A STRONG FUEL SMELL FROM INSIDE THE CABIN OF THE CAR. THE SMELL WAS SO STRONG THAT I FELT IT WAS IN MY BEST INTEREST TO DRIVE TO THE NEAREST EUROPEAN CAR SERVICE CENTER, SINCE THE NEAREST MB SERVICE CENTER IS 45 MINUTES AWAY. IT WAS DETERMINED THAT THE CHARCOAL FILTERS UNDER THE REAR SEAT WERE LEAKING, CAUSING FUEL TO POOL. WE CALLED THE MB SERVICE CENTER AND WAS TOLD THERE WAS A RECALL ON THE CHARCOAL FILTERS BUT IT WAS CLOSED. I WAS INCREDULOUS THAT SUCH A SERIOUS PROBLEM (ANY LEAKING FUEL ISSUE SHOULD BE CONSIDERED SERIOUS) WAS COMPLETELY IGNORED BY MB AND I WAS ON MY OWN. I HAD NO CHOICE BUT TO PAY TO HAVE THE FILTERS REPLACED AT MY EXPENSE OUT OF FEAR OF MY CAR EXPLODING. NOW, JULY 2012, THE CHARCOAL FILTER VALVE IS LEAKING AND CAUSING ANOTHER GAS ODOR. SO I STARTED RESEARCHING THIS ISSUE AND WAS SURPRISED TO FIND A GREAT NUMBER OF OTHER CONSUMERS FACING THE SAME ISSUES AS MYSELF. EVERYONE EXPERIENCING THESE ISSUES AFTER THE RECALL WAS CLOSED SEEMS TO BE IN THE SAME BOAT, MB REFUSING TO ISSUE ANOTHER RECALL AND/OR COVER THE COST OF THE REPAIRS. I BELIEVE THAT MB SHOULD BE RESPONSIBLE FOR CORRECTING ALL ISSUES RELATED TO LEAKING FUEL FOR THE CONTINUED SAFETY OF ALL MB OWNERS. QUITE FRANKLY, I'M SCARED TO DRIVE MY CAR! *JS

MY CAR WAS SUPPOSED TO HAVE THE INITIAL RECALL COMPLETED IN 2008. RECENTLY I NOTICED A STRONG GAS SMELL COMING FROM MY CAR AND HAS GOTTEN WORSE. I REMOVED THE REAR SEAT AND ACCESS COVER TO THE FUEL PUMP AND NOTICED A LARGE PUDDLE OF GAS ACCUMULATED/LEAKING AROUND THE FUEL PUMP SENDER UNIT AREA. ALSO THE PRODUCTION DATE OF THE PARTS WERE 2004, SO IT IS LIKELY THE DEALER DIDN'T DO ANYTHING BACK IN 2008. I NOW HAVE TO DRIVE WITH A CONSTANT SMELL OF GAS IN THE INTERIOR OF MY CAR AND CAN'T PARK IT IN THE GARAGE DUE TO RISK OF FIRE HAZARD. *JS

3EA13003 · 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

PE10017 · Driver Air Bag Circuit High Resistance
Opened May 14, 2010 · Closed Nov 24, 2010
Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal; Electrical System; Electrical System:wiring; Electrical System:wiring:interior/under Dash
Mercedes-Benz USA (MBUSA) has reported a high number of warranty claims for air bag warning lamp illumination due to a diagnostic fault code 9103 or 9123 indicating a high resistance in the driver's frontal air bag firing circuit.MBUSA's testing and evaluation have shown that this condition is the result of a faulty connector (specifically, improper wire crimp) but that it will not prevent proper deployment of the driver's frontal air bag.The faulty connector can cause the air bag circuit resistance levels to exceed the threshold that illuminates the air bag warning lamp, but they do not exceed a higher limit at which proper deployment of the air bag may no longer occur.The agency believes that further expenditure of agency resources does not appear to be warranted at this time.The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.The agency will monitor the issue and reserves the right to take future action if warranted by the circumstances.During the investigation, ODI learned that MBUSA will initiate a warranty extension program to address the faulty connectors in subject model year 2005 and 2006 E-Class and other MBUSA model/model year vehicles.This action will extend the warranty coverage for this issue to 10 years or 100,000 miles, whichever occurs first.MBUSA will notify all affected vehicle owners of this action.A bulletin describing this program is available in the investigative file.
