Reported: 2012-12-03 (December 3, 2012)

Mercedes-Benz is recalling certain model year 2011-2012 S400, S550, S550 4Matic, S63 AMG, C300, C300 4Matic, E350, GLK350, GLK350 4Matic, CL550 4Matic, and CL63 AMG vehicles manufactured from April 18, 2011, through July 12, 2011. 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.

Consequence: If the fuel filter flange cracks, it will leak fuel which may lead to a fire if an external ignition source is present.

Remedy: 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.

Reported: 2017-01-10 (January 10, 2017)

These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules, and used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the front air bags, these inflators may rupture due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.

Consequence: An inflator rupture may result in metal fragments striking the vehicle occupants resulting in serious injury or death.

Remedy: MBUSA will notify owners, and dealers will replace the front passenger air bag modules, free of charge. Owners were sent an interim notification in March 2017. Second notices started going out in October 2018 and continue to be mailed as parts become available. Owners may contact MBUSA customer service at 1-877-496-3691
