Vehicles Affected: Approximately 225 model-year 2016 Mercedes-Benz SLK300 roadsters manufactured from June 2 to July 14, 2015, and equipped with a nine-speed automatic transmission
The Problem: The backup power supply for the ignition switch may not have been properly connected. 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. Without the backup power supply, the only way to keep the vehicle from moving is to press the brake pedal, and as soon as the driver attempts to exit the vehicle, the vehicle may roll, increasing the risk of an injury.
The Fix: Dealers will correct the ignition switch wiring and perform a software update for free.
What Owners Should Do: The automaker will begin notifying owners in May. Owners can call the automaker at 800-367-6372 or the National Highway Traffic Safety Administration’s vehicle-safety hotline at 888-327-4236, or go to www.safercar.gov, for more info.
