Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2014 E350 and E350 4Matic sedans manufactured June 4, 2014, to July 9, 2014. The affected vehicles were built with a fuel feed line that has a single flare fitting instead of a double flare fitting.
Risk: If the fuel feed line has the incorrect flare fitting, the connection between the fuel hose and the fuel feed line might develop a leak or may completely disconnect. Leaking fuel in the presence of an ignition source increases the risk of a fire and if the fuel feed line disconnects, the vehicle would stall, increasing the risk of a crash.
Remedy: MBUSA will notify owners, and dealers will install the correct fuel line, free of charge. This recall began on January 11, 2016. Owners may contact Mercedes-Benz customer service at 1-800-367-6372.
