Vehicles Affected: Approximately 140 model-year 2017-18 Ford F-150 pickup trucks manufactured at Ford's Dearborn Truck Plant in Michigan between Oct. 20, 2016, and March 5, 2018, and at the Kansas City Assembly Plant in Missouri between Dec. 22, 2017, and Feb. 26, 2018; model-year 2018 Expedition SUVs manufactured at the Kentucky Truck Plant between Nov. 28, 2017, and Feb. 14, 2018; model-year 2018 Mustang muscle cars manufactured at the Flat Rock Assembly Plant in Michigan between Nov. 6, 2017, and Feb. 12, 2018; and model-year 2018 Lincoln Navigator SUVs manufactured at the Kentucky Truck Plant between Dec. 13, 2017, and March 8, 2018
The Problem: A potentially missing roll pin that attaches the park pawl rod guide cup to the transmission case may cause the transmission to eventually lose the Park function even when the shifter and instrument panel display indicate the vehicle is in Park. This condition would allow the ignition key to be removed, with no instrument-panel warning message or warning chime when the driver's door is opened that indicates the vehicle is not secured in Park. If the parking brake is not applied, this could result in unintended vehicle movement, increasing the risk of an injury or a crash.
Ford stated that is not aware of any reports of accidents or injuries related to this condition.
The Fix: Dealers will inspect the transmission for a missing park pawl rod guide cup roll pin and will install the roll pin, if necessary, for free.
What Owners Should Do: Ford did not immediately announce an owner-notification schedule. Owners can call the automaker at 866-436-7332 or the National Highway Traffic Safety Administration's vehicle-safety hotline at 888-327-4236, or visit its website to check their vehicle identification number and learn more.
