2011-2012 Mercedes-Benz Vehicles Recalled For Fire Risk

December 11, 2012

Mercedes-Benz is conducting a voluntary safety of certain 2011 and 2012 vehicles over concerns that a faulty fuel filter flange may pose a fire risk.

A notice on the National Highway Traffic Safety Administration (NHTSA) site puts the number of vehicles potentially affected by the recall at 5,800. Affected vehicles were built from April 18, 2011 through July 12, 2011 and include the following models:

The problem

Documentation from Mercedes-Benz (PDF) describes the problem as an irregularity in the structure of fuel filter flanges caused by issues during the injection molding process. As a result of the irregularity, the fuel filter flange may crack under high temperatures.

The NHTSA bulletin states: “If the fuel filter flange cracks, it will leak fuel which may lead to a fire if an external ignition source is present.”

According to Mercedes-Benz, “In most cases, fuel cannot leak through this structural irregularity in the flange.” The automaker goes on to say that in some cases of operating pressure along with high operating temperatures “could over time lead to the development of a crack in the flange, which may result in fuel leakage and/or loss of fuel system pressure and flow.”
