Ford is recalling more than 741,000 vehicles in the U.S. because a transmission defect could damage the park system, potentially increasing the risk of a crash or injury due to unintended movement. The recall covers specific models from 2018 to 2021, including the Ford F-150, Lincoln Aviator, Ford Explorer, Lincoln Navigator, and Ford Expedition. The issue stems from the temporary engagement of the transmission parking pawl while the vehicle is in motion under certain shifts, which can damage park system components.

If the park system is damaged, the vehicle's ability to remain stationary when in "park" might be compromised if the parking brake is not applied, leading to a rollaway risk. Ford attributes the issue to insufficient fluid flow to the park valve during certain transmission downshifts, which can briefly engage the parking pawl. The automaker is aware of 24 allegations of property damage and nine alleged injuries, including two emotional injuries, related to this defect. A wrench-shaped warning light in the instrument cluster may indicate a problem.

To address the problem, vehicle owners will be notified by mail and instructed to take their vehicles to a Ford or Lincoln dealer. Dealers will update the Powertrain Control Module software to the latest level, free of charge, to prevent problematic shifts. They will also inspect the transmission for any park system damage and replace affected components as needed, also at no cost to the owner. This recall is one of Ford's largest actions of the year, impacting a significant number of their popular SUV and truck models. Vehicle owners can contact Ford customer service at 1-866-436-7332 or the National Highway Traffic Safety Administration (NHTSA) Vehicle Safety Hotline at 1-888-327-4236 for more information.
