Ford F-150: recalls, complaints and investigations.

Opened 2026-01-30Closed not closedPOWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM)

On March 21, 2025, NHTSA’s Office of Defects Investigation (ODI) opened a Preliminary Evaluation (PE25002) to investigate instances of unexpected transmission downshifting without driver input in model year (MY) 2015-2017 Ford F-150 vehicles (subject vehicles) manufactured by Ford Motor Company (Ford). The complaints allege that, without warning or driver input, the subject vehicles experienced a sudden and rapid deceleration often accompanied by temporary rear wheel lockup, seizure, or skidding, resulting in a loss of vehicle control that increases the risk of crash and injury to all motorists, including those not within the subject vehicles. The MY 2015 and MY 2016 F-150 vehicles were equipped with the “6R80” transmission, while the MY 2017 vehicles were equipped with either the “6R80” transmission or the “10R80” transmission. This investigation was limited to MY 2015-2017 Ford F-150 with the “6R80” transmission. ODI identified 329 Vehicle Owners Questionnaires (VOQs) related to this investigation and sixty percent of these consumers were interviewed to confirm the details of their allegations. Consumers reported that their vehicles’ transmission suddenly downshifted to a lower gear, often to 1st or 2nd gear, without driver input or advance warning. Consumers described the downshift events to be regular and repeated occurrences, with some consumers stating that they no longer drive the vehicle due to safety concerns. Forty-three percent of consumers reported experiencing at least one wheel lockup event, during which the rear tires locked, screeched, or skidded during the transmission downshift. ODI also found that 114 of the 329 consumers reported having their vehicle’s molded lead frame or valve body assembly (which comes with a molded lead frame) replaced, 80 of which were confirmed through consumer submitted repair invoices. In its response to ODI’s Information Request, Ford provided an assessment of potential root cause of failure for the subject vehicles and how this failure is different from the failure associated with MY 2011-2014 Ford F-150 vehicles that was addressed by four safety recalls (16V-248, 19V-075, 19V-433, and 24V-444). Ford has identified that the defect in the recalled vehicle population involved lead frame supplier production issues resulting in signal loss from the Output Shaft Speed (OSS) sensor. Ford has identified that the alleged defect in the subject vehicle population involved degradation of electrical connections within the lead frame due to thermal cycling and vibration over extended time in service resulting in signal loss from the Transmission Range Sensor (TRS). Signal loss from the TRS can result in an unintended shift to neutral, unintended upshift, or unintended downshift which are regulated by a gear “shift map” based on the vehicle’s speed at the time of signal loss. According to Ford’s “shift map”, at speeds between 35-64 mph, the maximum allowable downshift would be to 2nd gear (i.e. a 6th to 2nd gear downshift event) which Ford has designated to represent the worst-case scenario for subject vehicles. Ford has also acknowledged that the worst-case scenario may also involve temporary wheel lockup. However, Ford has stated that the failure mechanism in the MY 2011-2014 F-150 vehicles—previously addressed through recalls—primarily involved OSS sensor signal loss that could result in 6th to 1st gear downshift events. This OSS-related failure mode is distinct from the TRS-related signal loss identified in the subject vehicle population. ODI has identified an additional potential safety defect associated with the alleged defect in the subject vehicles. Preliminary testing performed by NHTSA’s Vehicle Research Test Center (VRTC) showed that when the TRS experiences an intermittent signal loss, one possible outcome is a change in vehicle direction. Specifically, if a vehicle is operating in reverse up an incline when the TRS signal loss occurs, then the vehicle may shift into neutral causing the vehicle to change directions and roll forward. ODI is opening this Engineering Analysis (EA) to, among other things, perform component-level testing and vehicle testing, as well as review additional technical information to better understand the alleged defect that has been identified.

On September 23, 2020, Ford Motor Company (Ford) filed a noncompliance recall report under 49 CFR Part 573 (NHTSA Recall No. 20V-575), recalling 620,246 Model Year (MY) 2020 Ford F-150, F-250, F-350, F-450, F-550, Explorer, Mustang, Transit, Expedition, Escape, Ranger and Edge, and Lincoln Nautilus and Corsair vehicles for a noncompliance with Federal Motor Vehicle Safety Standard (FMVSS) 111, Rear Visibility. Ford's recall described the noncompliance as insufficient electrical conductivity within the printed circuit board (PCB) internal to the camera leading to intermittent rearview camera operation. The supplier of the cameras was Magna Electronics.According to Ford's chronology in the Part 573, during the period February-April 2020, Ford identified and monitored warranty claims pertaining to intermittent or inoperative rearview cameras. Ford reviewed supplier product changes, focusing on changes introduced by the supplier in the October-November 2019 time frame. The Part 573 stated that the issue was brought to Ford's Critical Concerns Review Group (CCRG) for review on May 12, 2020.On July 7, 2020, NHTSA's Vehicle Research and Testing Center (VRTC) informed the Office of Defects Investigation (ODI) of a trend of MY 2020 Escape vehicles with rearview camera malfunctions. ODI contacted Ford the next day, providing five Vehicle Owner Questionnaires (VOQs) alleging inoperative rearview cameras. On July 15, 2020, Ford met with NHTSA to discuss the rearview camera issue. In a subsequent August 24, 2020 meeting, ODI and NHTSA's Office of Vehicle Safety Compliance (OVSC) met with Ford to discuss the recall status and additional VOQs. Ford presented rate and scope data for many of its MY 2020 products during the August 2020 meeting indicating high failure rates for certain models.This RQ is being opened to investigate both the timeliness and scope of Ford's rearview camera recall (20V-575), and Ford's compliance with reporting requirements.The subject reports referenced in the opening resume are identified by the following ODI reference numbers which can be reviewed at NHTSA.gov: 11349813, 11344126, 11342696, 11341486, 11340254, 11337274, 11331444, 11330875, 11329235, 11316960, 11343521, 11341884, 11337226, 11344018, and 11339573.
