NHTSA campaign 16V211000 · Electrical System · filed Apr 13, 2016 · verified Jul 30, 2026
The defect
Mercedes-Benz USA, LLC (MBUSA) is recalling certain model year 2016 SLK300 vehicles manufactured June 2, 2015 to July 14, 2015 and equipped with a nine-speed automatic transmission. The backup power supply for the ignition switch in the affected vehicles may not have been properly connected. As a result, if the vehicle is being driven and there is a loss of power from the main vehicle battery, the transmission cannot be shifted to "Park" nor can the electric parking brake be applied.
The risk
In this situation, without the backup power supply, the only way to keep the vehicle from moving is to press the brake pedal. As soon as the driver attempts to exit the vehicle, the vehicle may roll, increasing the risk of injury.
