Plain-English summary

Mercedes-Benz USA, LLC. is recalling certain model year 2014 S63 AMG sedans and 2015-2016 S63 AMG 4Matic sedans and coupes. The affected vehicles were manufactured between May 14, 2013, and September 18, 2015. A total of 3,177 vehicles are included in this recall.

The recall addresses a software error within the engine control unit that may cause the vehicle to stall when coasting to a stop, such as at a traffic light. The source notes that this stall may be mistaken for the planned shut-down of the ECO-Start function. However, the engine will not restart automatically after the driver releases the brake pedal, which immobilizes the vehicle and increases the risk of a crash.

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 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
