The NHTSA safety investigation was conducted after Ford’s major recall in June 2024, which covered over 550,000 F-150 vehicles from the 2014 model year due to a similar transmission defect.
The recall was necessary to address an intermittent loss of signal between the transmission speed sensor and the transmission control module, which could cause a sudden shift to first gear, regardless of the vehicle's speed. These 2014 F-150 models were also equipped with a 6-speed transmission.
Prior to this recall, Ford received 300 warranty reports, 96 field reports, and 124 customer complaints related to unexpected downshifts in 2014 F-150 pickup trucks. This included 40 reports of rear-wheel lockup and/or loss of vehicle control, according to NHTSA data.
Ford determined that the cause of the sudden downshifting in 2014 F-150 models was an electrical issue caused by contamination and corrosion in the connector within the output shaft speed sensor circuit. The fix involved updating the powertrain control module calibration in these vehicles.
According to NHTSA, Ford has issued 29 recalls since January 1. A February recall covered up to 240,510 2020-2021 model year Explorer SUVs and Lincoln Aviators due to improperly secured front seat belt anchor bolts and second-row seat retention bolts.
Ford’s 29 recalls this year are a continuation of dozens of other recalls in 2024. Last year, the automaker issued a total of 67 recalls, the second-highest number after Stellantis North America, which had 72 recalls.
