The problem
Mercedes-Benz USA LLC (Mercedes-Benz) is recalling certain model year 2014 S63 AMG sedans and 2015-2016 S63 AMG 4Matic sedans and coupes manufactured May 14, 2013, to September 18, 2015. In the affected vehicles, due to a software error within the engine control unit, the vehicle may stall when coasting to a stop, such as at a traffic light.
The risk
The vehicle stall may be interpreted by the driver to be a planned shut-down as part of the ECO-Start-function. However, the engine will not restart automatically after releasing the brake pedal, immobilizing the vehicle and increasing the risk of a crash.
The fix
Mercedes-Benz will notify owners, and dealers will update the engine control unit software, free of charge. The recall BEGAN ON DECEMBER 2, 2015. Owners may contact Mercedes-Benz customer service at 1-800-367-6372. Mercedes-Benz's number for this recall is 2015100003.
