What happened
Ford said it is recalling more than 4.3 million vehicles after identifying a software issue that could cause trailer brakes not to function while towing. The company said the problem can occur if the vehicle’s Integrated Trailer Module loses communication with the vehicle, which may also affect trailer brake and turn-signal lights.
Affected vehicles
The recall affects certain model-year vehicles including:
- 2021–2026 F-150
- 2022–2026 Super Duty trucks
- 2024–2026 Ranger
- 2022–2026 Expedition
- Maverick
- Lincoln Navigator
- 2026 Transit
What drivers may notice
If the communication loss occurs, Ford said drivers may see a "Trailer Brake Module Fault" message on the instrument panel. The turn-signal indicator may flash rapidly, and a "Blind Spot Assist System fault" message may also appear.
Remedy and timeline
Ford said software updates will be available for most vehicles beginning March 17. The company said updates can be delivered over the air (OTA), through dealerships, or via mobile service, with OTA updates expected to be deployed for all vehicles by May.
Why it matters
For drivers who tow trailers, reliable trailer braking is a safety-critical function. The recall highlights how software and module communication issues can create real-world safety risks—especially for larger vehicles frequently used for hauling and towing.
