11V493000 · Tires:Pressure Monitoring And Regulating Systems
Reported: 2011-10-03 (October 3, 2011)
Mercedes-Benz USA, LLC (Mercedes Benz) is recalling certain model year 2011-2012 S550, S550 CGI, S63, S600 Bi-Turbo, S65 AMG, S550 4-Matic, and S550 CGI 4-Matic and S400 Hybrid vehicles manufactured from March 3, 2011, through July 30, 2011, for failing to comply with the requirements of Federal Motor Vehicles Safety Standard (FMVSS) number 138, "Tire Pressure Monitoring System (TPMS)." The tire pressure monitoring system indicators may only illuminate for a portion of the time required by the standard and under certain conditions may not re-illuminate immediately after the vehicle is restarted as required.
Consequence: If all four wheel sensors in the subject vehicles are simultaneously malfunctioning or missing, the TPMS will provide an initial warning, but this warning will not automatically repeat on subsequent ignition cycles, failing to remind the driver that the system is offline. Driving unknowingly with incorrectly inflated tires may result in sudden tire failure, increasing the risk of a crash.
Remedy: Mercedes Benz will notify owners, and dealers will reprogram the tire pressure monitoring unit, free of charge. The recall began on September 12, 2014. Owners may contact Mercedes Benz at 1-800-367-6372.
NHTSA campaign record ↗12V557000 · Fuel System, Gasoline
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.
