Ford Issues Major Recall for 4.3 Million Vehicles Due to Software Glitch

Ford Motor Company is recalling approximately 4.3 million vehicles in the United States due to a software defect in the Integrated Trailer Module (ITRM). This issue may lead to the failure of trailer brakes and exterior lights, significantly increasing the risk of accidents while towing. The recall encompasses various models, including the 2021-2026 Ford F-150, 2022-2026 Ford F-250 Super Duty, Lincoln Navigator, Expedition, Maverick, and some Ranger and E-Transit vehicles.

The software glitch can cause a loss of communication between the towing vehicle and the trailer, particularly when the vehicle is first started. This malfunction may result in the trailer's brake lights and turn signals becoming inoperable, and in some cases, the trailer's braking function may also be lost. Ford has reported 407 incidents that may be related to this issue, although it has stated that it is unaware of any accidents or injuries linked to the defect.

Ford has announced that it will address the software issue through an over-the-air update, which is expected to begin deployment in May 2026. Customers will also have the option to visit a Ford or Lincoln dealership for the update at no cost. The National Highway Traffic Safety Administration (NHTSA) has emphasized that non-functional trailer lights or brakes can severely impair a driver's ability to control the trailer, thereby increasing the risk of a crash.

While Ford has taken steps to rectify the issue, critics have raised concerns regarding the frequency of recalls associated with the automaker. In 2025, Ford issued a record 103 safety recalls, which has drawn scrutiny from regulators and industry observers. The current recall is part of a broader trend of safety issues that have plagued the company, prompting calls for enhanced quality control measures.

There are discrepancies regarding the exact number of vehicles affected by the recall. While Ford estimates that one percent of the recalled population may experience the software issue, the total number of vehicles involved is consistently reported as approximately 4.3 million. Additionally, the timeline for the rollout of the software update has been noted as starting in May 2026, but specific details on the completion of repairs across all affected vehicles remain unclear.
