Ford is recalling over 600,000 vehicles in Canada and around 4.3 million in the U.S. due to a software problem that could lead to trailer brake malfunctions and exterior light failures. The affected models include select 2021-2026 F-150s, 2022-2026 Super Duty trucks, 2024-2026 Rangers, and 2022-2026 Mavericks.
To address the issue, Ford plans to roll out an over-the-air software update for the impacted vehicles. Customers can also opt for mobile service or visit a Ford dealership to receive the update. The software update is expected to be available for most Canadian vehicles by the end of March and for all vehicles by the end of May.
The software glitch can disrupt communication between the vehicle and the trailer when towing, leading to non-functional stop lamps and turn signals on the trailer, and potentially affecting the trailer’s braking system. The National Highway Traffic Safety Administration warns that malfunctioning trailer lights or brakes can compromise the driver’s control over the trailer, increasing the risk of accidents.
Drivers will receive a “Trailer Brake Module Fault” notification and notice rapid flashing of the turn signal indicator if their vehicle experiences communication loss with the trailer. Ford has identified 407 incidents possibly linked to the recall issue but has reported no accidents or injuries associated with it.
