Mercedes-Benz has announced a recall for vehicles with malfunctioning software.

The automobile manufacturer is recalling certain model year 2014 S63 AMG sedans and 2015-2016 S63 AMG 4Matic sedans and coupes. 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 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 company believes that about 3,000 vehicles are potentially affected by this issue.

Mercedes-Benz will notify owners, and dealers will update the engine control unit software, free of charge. The recall is expected to begin on December 8, 2015.

Owners with questions about the recall can contact Mercedes-Benz customer service at (800) 367-6372.
