Fiat Chrysler Automobiles (FCA) is recalling 39,456 Jeep Wrangler SUVs and Dodge Grand Caravan minivans because of a faulty brake switch.

The defect makes it possible to shift the vehicles out of Park without depressing the brake pedal, and the brake lights can also can get stuck on, according to the National Highway Traffic Safety Administration.

NHTSA says the conditions can increase the risk of a crash, although FCA says it is not aware of any injuries or crashes related to the problem. An FCA spokesman added that the automaker is unaware of any instances of the shifter inadvertently moving out of Park.
