Ford Motor Company is recalling approximately 161 2017-18 Ford F-150 and 2018 Ford Expedition, 2018 Lincoln Navigator and 2018 Ford Mustang vehicles in North America with 10R80 transmissions because the roll pin that attaches the park pawl rod guide cup to the transmission case may be missing.

If the pin is absent, after repeated use, the transmission may lose park function even when the shifter and instrument display indicate the vehicle is in park. In the event the parking brake is not applied, this scenario could result in unintended vehicle movement, increasing the chance of injury or a crash.

Ford is not aware of any accidents or injuries associated with this condition.

To remedy the problem, dealers will inspect the transmission for a missing park pawl rod guide cup roll pin and will install the roll pin if required at no cost to owners.

• 2017-18 Ford F-150 vehicles built at Dearborn Assembly Plant, Oct. 20, 2016 to March 5, 2018
