Ford recalls 1.4 million F-150s over software issue causing downshifts

Ford is pulling 1,392,935 F-150 pickups in the United States after a software defect in the powertrain control module was linked to sudden downshifts that can leave drivers fighting for control. The affected trucks are 2015 to 2017 model-year F-150s with six-speed automatic transmissions, and the fix is a free PCM calibration update at Ford dealers.

The defect is not a subtle drivability complaint. NHTSA described the problem as an unexpected transmission downshift without warning or driver input, often accompanied by temporary rear wheel lock-up. That combination can abruptly change the truck’s balance and raise the risk of a crash, especially if the driver is moving at speed or in traffic. NHTSA said Ford was aware of two potentially related injuries and one accident, giving the recall a real-world safety dimension that goes beyond preventive maintenance.

The scope of the investigation helps explain why the repair finally moved forward. NHTSA’s engineering analysis, opened January 30, 2026, covered 2015 to 2017 F-150s and listed 1,270,970 vehicles under review. In its summary, the agency logged 444 total incidents, including 329 consumer complaints and 226 manufacturer reports. It recorded no crashes, fires or fatalities in the investigation summary, but 43% of consumers reported at least one wheel-lockup event, and many said they no longer felt comfortable driving the truck.

Ford had already opened its own internal investigation on February 8, 2024, after reports of unexpected downshifting in 2014 F-150s began rising. NHTSA then opened Recall Query RQ24-005 on March 27, 2024, and the agency’s chronology shows the issue had been the subject of earlier queries and recalls stretching back years. Ford’s analysis pointed to electrical connections in the lead frame degrading over time from heat cycling and vibration, which can cause signal loss from the transmission range sensor and trigger the downshift.

The recall also exposes the burden of safety oversight on America’s bestselling truck. Ford has dealt with previous F-150 transmission actions, including 16V-248, 19V-075, 19V-433 and 24V-444, yet complaints tied to the six-speed automatic persisted. That history suggests that a modern vehicle problem can linger across model years, resurface in new populations and only be forced into a broad remedy after a federal investigation builds enough evidence. For Ford, the software update is straightforward; for owners, the wait is for notice, scheduling and a dealer visit before the trucks are made safe again.
