Summary

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.

Notes

Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 'TTY 1-800-424-9153', or go to www.safercar.gov.
