Model years: 2020
Problem: Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2019 AMG G63, C300, E300, G550, AMG GT63, AMG GT53, 2019-2020 A220, GLA250, GLC300, 2016 C300, 2020 AMG A35, AMG C43, AMG C63, CLA250, E350, E450, GLB250, GLE450, GLS450, GLS580, S560, and SL550 vehicles equipped with a gasoline engine.

Fuel system, gasoline:delivery
Model years: 2014
Problem: 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.
Fix: 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.
Fuel system, gasoline

Due to an irregularity stemming from the molding process of the fuel filter flange, the fuel filter flange may crack when operated in high temperatures.
Risk: If the fuel filter flange cracks, it will leak fuel which may lead to a fire if an external ignition source is present.
Fix: Mercedes-Benz will notify owners, and dealers will replace the fuel filter, free of charge. The recall campaign is expected to begin in February 2013. Owners may contact Mercedes-Benz at 1-800-367-6372.
