Read coverage & conditions01 / Owner-reported evidence
Categories attached to 1,437 distinct reports. A report can mention more than one component, so category totals can overlap.
These are reports made to NHTSA, not verified diagnoses. More reports can reflect more vehicles, more time on the road, or greater reporting activity.

04 / Agency investigations
An investigation is an inquiry into a potential concern. Its presence does not establish a defect, and a closed case does not certify a car’s condition.
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. To review the reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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. Based on NHTSA’s analysis of consumer data, information provided by Ford, and preliminary testing conducted by NHTSA’s VRTC, this Preliminary Evaluation is being upgraded to an Engineering Analysis (EA26001). During this Engineering Analysis, the agency plans 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 from this Preliminary Evaluation.

Find investigation PE25002On June 18, 2018, the Office of Defects Investigations (ODI) opened a Preliminary Evaluation (PE18-008) to investigate complaints alleging post-crash fires at the B pillar in the area of the seat belt pretensioners on MY 2014-2018 Ford F-150 Regular Cab, and Super Crew Cab Vehicles. On August 24, 2018, Ford Motor Company recalled (FSA 18S27 - NHTSA #18V568) the affected population. Ford's investigation found that some front seat belt pretensioners may generate sparks during deployment in excess of Ford's specification. Sparks in the pretensioner exhaust gases inside the lower portion of the B-pillar may subsequently ignite combustible components contained in the B-pillar, such as insulation or carpet, and may cause a subsequent vehicle fire. ODI also requested relevant information from other manufacturers to assess the potential scope of post-crash pretensioner fires. Ford will notify owners and require dealers to remove B-pillar insulation material and wiring harness tape, and install heat resistant tape, free of charge. The recall notification began September 28, 2018.Owners may contact Ford customer service at 1-866-436-7332.The VOQs associated with the closing of this investigation are: 11143035, 11130056, 11129828, 11128761, 11127993, 11127880, 11124717, 11123419, 11119651, 11119626, 11114065, 11113160, 11111822, 11097937, 11078447, 11014688
