Ford recalls 4.3 million vehicles due to software issue affecting trailer brakes and lights.

Ford is recalling 4.3 million vehicles in the U.S., including F-150s, F-250 Super Duties, Lincolns, and E-Transit vans from 2021 to 2026, over a software issue that may cause trailer brakes and exterior lights to fail when towing. The problem stems from a communication failure between the trailer module and vehicle systems, potentially leading to brake loss or nonfunctioning turn signals. Ford will fix the issue via over-the-air software updates, with no known crashes linked to the defect. The recall follows a reopened NHTSA investigation.
