Lack of Backup Power Supply Triggers Recall from Mercedes-Benz

Drivers may be unable to shift the vehicle into "Park"

May 3, 2016

Mercedes-Benz USA has announced a recall for a luxury vehicle due to an electrical defect.

The company is recalling certain model year 2016 SLK300 vehicles 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" and the electric parking brake cannot be applied.

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.

The manufacturer believes that about 225 vehicles are impacted by this malfunction.

Mercedes-Benz USA will notify owners, and dealers will correct the ignition switch wiring and perform a software update, free of charge. The recall is expected to begin in May 2016.

Owners with questions about this recall can contact the company's customer service line at (800) 367-6372.
