Ford will provide a convenient over-the-air update to the Integrated Trailer Module software in approximately 4,380,609 vehicles in the United States as part of a safety recall. Customers may also utilize mobile service or visit a Ford dealer to update the module. The recall affects certain 2021-2026 F-150, 2022-2026 Super Duty (F-250-600), 2024-2026 Ranger, 2022-2026 Expedition, 2022-2026 Navigator, 2022-2026 Maverick, and 2026 Transit vehicles.

This issue in the trailer control module may cause it to stop communicating with the vehicle, which typically happens when the vehicle is first started. If this occurs while a trailer is connected, the trailer’s stop lamps and turn signals will not illuminate. Additionally, on vehicles equipped with a “High series” trailer module, the trailer’s braking function will also be lost. These conditions result in a noncompliance with federal safety standards and can reduce a driver’s ability to control an attached trailer while making it less visible to other drivers, increasing the risk of a crash.

If a vehicle experiences this communication loss, the driver will see a “Trailer Brake Module Fault” message on the instrument panel cluster, and the turn signal indicator will flash rapidly. A “Blind Spot Assist System fault” message may also appear on the dashboard.

Ford is not aware of any accidents, injuries, or fires attributed to this issue.

Starting March 17, the update will be available for the majority of vehicles via Over-the-Air (OTA), dealership, or mobile service. OTA updates are expected to be deployed for all vehicles by May.
