Ford is recalling more than 4.3 million trucks, SUVs, and vans to fix a software defect in the trailer module that can disable brake lights, turn signals, and — in some vehicles — braking systems.
No injuries or crashes were reported, but the problem poses a serious safety hazard.
The recall affects some of Ford’s most popular vehicles, including F-Series trucks and large SUVs that are commonly used for towing heavy loads — from RVs and boats to work equipment and livestock trailers.
If trailer lighting or braking systems fail, especially at highway speeds, the consequences could be deadly. Other drivers may not see that the vehicle is slowing down or turning if the trailer lights fail to illuminate. Or if the trailer brakes fail, the driver might lose control — particularly when towing heavy loads.
According to Ford’s Safety Recall Report filed with the National Highway Traffic Safety Administration (NHTSA), the problem involves a software-controlled component that manages communication between the vehicle and its trailer.
If there is a communication failure while a trailer is connected, several safety features may not work properly:
- Trailer brake lights may not illuminate
- Turn signals may fail to operate correctly
- On certain higher-trim trucks, the trailer’s braking system may stop functioning
The recall covers approximately 4,380,609 vehicles nationwide. Ford said it received hundreds of warranty claims related to the problem, but estimated that only 1% of those vehicles may actually experience the defect.
