Rollaway risk prompts Mercedes-Benz SLK300 recall

Loss of power from the vehicle battery can prevent the vehicle from being put into \'Park.\'

Mercedes-Benz has launched a small-batch recall for a few hundred 2016 SLK300 convertibles.

The backup power supply for the ignition switch may not have been properly connected in the affected vehicles, effectively disabling the electric parking brake and preventing the transmission from being shifted into 'Park.'

"In this situation, without the backup power supply, the only way to keep the vehicle from moving is to press the brake pedal," the recall documents note. "As soon as the driver attempts to exit the vehicle, the vehicle may roll, increasing the risk of injury."

The issue appears to be limited to vehicles equipped with a nine-speed automatic transmission. Service technicians will be instructed to correct the switch wiring and perform a software update to restore proper behavior.

It is unclear if the defect has been associated with any accidents or injuries.
