WASHINGTON — Mercedes-Benz USA is recalling 223 2016 Mercedes-Benz SLK300 luxury roadsters because of a rollaway risk, according to the National Highway Traffic Safety Administration.
The vehicles are 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," said NHTSA in its recall summary. "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.
"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."
A Mercedes-Benz spokeswoman did not respond immediately to a query from Edmunds asking if there are any injuries or accidents linked to the recall.
The affected SLK300 roadsters were built from June 2, 2015 to July 14, 2015.
Mercedes-Benz dealers will correct the ignition switch wiring and perform a software update. The recall is expected to begin sometime in May. Owners can contact Mercedes-Benz USA customer service at 1-800-367-6372.
Edmunds says: Owners of these vehicles should be prepared to schedule a service appointment with their dealer this month.
