Defect

Mercedes-Benz USA, LLC. (MBUSA) is recalling certain model year 2015 C300 4matic and C400 4matic vehicles manufactured April 7, 2014, to July 25, 2014. In the affected vehicles, the fuel delivery module may be improperly secured to the fuel tank. Secondly, electrical wires that connect to the fuel delivery module might have been pinched between the flange of the fuel delivery module and the tank.

Consequence

If the locking plate is not properly secured to the fuel delivery module it may become loose, and leak fuel, increasing the risk of a fire. If the electrical wires are pinched, the fuel pump may stop working, resulting in a stall, thereby increasing the risk of a crash.

Remedy

MBUSA will notify owners, and dealers will inspect the vehicles for improperly secured locking plates and pinched wires, correcting the vehicles as necessary, free of charge. The recal began on April 24, 2015. Owners may contact MBUSA customer service at 1-800-367-6372. MBUSA's number for this recall is 2015030004.
