THE PURPOSE OF THIS IS TO ALERT YOU OF A SAFETY HAZARD / PRODUCT DEFECT OF THE SEATBELT BUCKLE IN THE 2007 MERCEDES BENZ E350 4MATIC WAGON (?MB E350 WAGON?). I HAVE SENT A SIMILAR LETTER TO MERCEDES BENZ REPORTING THE SITUATION. ON AUGUST 7, 2015 WHILE RIDING IN THE FRONT PASSENGER SEAT OF AN MB E350 WAGON, I PLACED MY LEFT HAND ON THE LEFT SIDE OF MY SEAT NEAR THE SEATBELT BUCKLE, AS LEVERAGE IN ORDER TO ADJUST MY SITTING POSITION. AS I SHIFTED MY POSITION, THE SEATBELT MOVED THROUGH THE INSERTING (TOP) PART OF THE BUCKLE, AND IN THE PROCESS SEVERELY AND PAINFULLY PINCHED THE SKIN ON THE INSIDE OF MY LEFT FOREARM. ALTHOUGH THE SEATBELT BUCKLE ?LET GO? OF MY SKIN IT CAUSED A SERIOUS CONTUSION: WITHIN SECONDS OF THE INCIDENT, A PAINFUL, 2-3INCH LONG, RAISED/SWOLLEN CONTUSION DEVELOPED ON MY FOREARM. THE CONTUSION QUICKLY TURNED VERY DARK RED AS THE BLOOD CONTINUED TO POOL UNDER MY SKIN. THINKING THIS WAS A ONE OFF OCCURRENCE, FEW MINUTES LATER, I ONCE MORE ATTEMPTED TO SHIFT MY SITTING POSITION IN THE SAME MANNER AS ABOVE, ONLY TO SUFFER THE EXACT SAME INJURY AGAIN. THE SEATBELT BUCKLE CAUSED INJURY TO A SMALLER AREA BUT THIS TIME IT SLIGHTLY BROKE THE SKIN. AGAIN,A PAINFUL DARK RED SWOLLEN CONTUSION DEVELOPED IMMEDIATELY. (ON 9.22.2015 I MAILED A LETTER TO THE NHTSA WITH 4 PICTURES OF MY FOREARM FOR YOUR REFERENCE. PIC #1-3 WERE TAKEN IMMEDIATELY FOLLOWING THE INJURIES AND PICT #4 WAS TAKEN SEVERAL DAYS LATER. BOTH INJURIES WERE VERY PAINFUL WHEN THEY OCCURRED AND MY ARM AS QUITE SORE FOR SEVERAL DAYS LATER.) FOLLOWING MY INJURIES, I ASKED MY FRIENDS AND FAMILY IF THEY HAD EXPERIENCED THE SAME INJURY CAUSED BY THE SEATBELT BUCKLE, AND SEVERAL OF THEM HAD. I DO NOT WISH TO SPECULATE HOW SEVERE THE INJURIES WOULD BE IF THIS OCCURS TO AN ELDERLY INDIVIDUAL WHOSE SKIN IS OFTEN MORE DELICATE.

1EA13003 · 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
