Recalls and investigations

4 recalls on the transmission and drivetrain cover the 2017 model year. A recall on the same system isn't always the same failure, so read the defect text.

26V-237Apr 14, 2026
Power Train:Automatic Transmission

Ford Motor Company (Ford) is recalling certain 2015-2017 F-150 vehicles. A loss of signal between the transmission range sensor and the powertrain control module can cause the transmission to unexpectedly downshift into second gear.

Risk and remedy
Risk: Unexpectedly downshifting into second gear may result in a loss of vehicle control, increasing the risk of a crash.
Remedy: Dealers will update the powertrain control module software, free of charge. Owner notification letters were mailed July 24, 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26S28. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on April 15, 2026.
18V-213Apr 4, 2018
Power Train:Automatic Transmission

Ford Motor Company (Ford) is recalling certain 2017-2018 Ford F-150 and 2018 Ford Expedition and Mustang and Lincoln Navigator vehicles equipped with 10-speed automatic transmissions. A roll pin may not have been installed in the transmission, potentially causing a loss of the "Park" function.

Risk and remedy
Risk: Despite the transmission shift lever being placed in 'Park' and the instrument panel display indicating 'Park,' the vehicle may roll away after it has been exited if the parking brake has not been applied, increasing the risk of injury or a crash.
Remedy: Ford will notify owners, and dealers will inspect the transmission to make sure it has the roll pin, installing one if it is missing, free of charge. The recall began on April 13, 2018. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 18S09.
17V-671Oct 24, 2017
Power Train:Automatic Transmission:Lever And Linkage:Column Shift

Ford Motor Company (Ford) is recalling certain 2017 F-150 vehicles equipped with ten-speed transmissions. The pin that attaches the transmission shift linkage to the transmission may come out, preventing the transmission from responding to movement of the shift lever.

Risk and remedy
Risk: The disconnected linkage may cause the vehicle to not move forward or backward as selected by the driver with the shift lever. Additionally, despite selecting 'Park', if the parking brake is not applied, the vehicle may roll. Either scenario increases the risk of a crash.
Remedy: Ford will notify owners, and dealers will replace the roll pin with an updated part, free of charge. The recall is expected to begin December 2017. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 17S36.
17V-053Jan 24, 2017
Power Train:Automatic Transmission:Gear Position Indication (Prndl)

Ford Motor Company (Ford) is recalling certain 2017 F-150 trucks equipped with an eight-inch productivity screen. In these vehicles, the instrument cluster may lose power after the initial vehicle start-up in cold ambient temperatures. Several gauges, including the transmission gear position indicator, may not illuminate. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicles Safety Standard (FMVSS) number 102, "Transmission shift position sequence, starter interlock, and transmission braking effect."

Risk and remedy
Risk: If the transmission gear position indicator fails to illuminate, the driver may be unable to tell the transmission shift position, increasing the risk of a crash or injury from unintended vehicle movement.
Remedy: Ford will notify owners, and dealers will reprogram the instrument cluster, free of charge. The recall began February 20, 2017. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 17C01.

Unintended transmission downshift and rear wheel lock-up. Open, led to recall 26V-237.

NHTSA summary
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 repo

Unintended transmission downshift. Closed jul 29, 2024, led to recall 24V-444.

NHTSA summary
In September 2016, Ford Motor Company (Ford) issued safety recall 16V-248 which included certain model year (MY) 2011-2012 Ford F-150 vehicles equipped with 6-speed (6R80) automatic transmissions. This recall was in response to allegations of unintended, unexpected vehicle transmission downshifting to a lower gear without warning, often accompanied by temporary rear wheel lock-up, increasing the risk of a crash and/or injury, and included approximately 153,581 vehicles. Ford identified the root cause of the unintended, unexpected vehicle transmission downshifting to a lower gear to be intermittent signal loss from the transmission’s Output Shaft Speed (OSS) sensor due to solder joint cracks on the OSS circuit board as a result of manufacturing process issues. The OSS sensor is mounted onto the molded lead frame and transmits changes in transmission shaft speed to the Powertrain Control Module (PCM). The remedy program described in safety recall 16V-248 involved reprogramming of the PCM to prevent unintended vehicle transmission downshifting from occurring. In December 2017, the Office of Defects Investigation (ODI) opened a Recall Query (RQ17-010) to assess the scope and remedy effectiveness of safety recall 16V-248. As a result of this ODI investigation, Ford issued safety recall 19V-075 to expand the scope of 16V-248 to include MY 2011-2013 Ford F-150 vehicles equipped with 6-speed (6R80) automatic transmissions and included approximately 1,263,051 vehicles.

What owners wrote

“Sudden and harsh downshifts happening at speeds above 40mph in normal drivign conditions. The vehicle now shudders while crusing and clunks into and out of gears. The 6R80 transmission now feels like it is slipping when giving the vehicle gas from a standstill.”

Filed Mar 30, 2026

“Torque converter failed. Started with slipping feeling in the rear end. Then got worse and worse before it was a constant slippage. Local dealer and repair shop both diagnosed as a torque converter and both strongly recommend replacing the torque converter and the transmission. Around $10,000”

Filed Mar 12, 2026

“The CDF drum bushing slipped, which seems to be a constant problem on the F150's, causing my truck transmission to fail while on the freeway. Looking online, several of these instances have occurred to other truck owners. The cost to repair this is astronomical and if Ford has been aware of the problem for so long, they should have recalled the trucks and fixed the problem.”

Filed Dec 9, 2025

“The transmission has been chattering, slipping, and making weird noises since I bought the truck. There are times where the truck will roll forward several feet after I've placed the shifter in park and remove my foot from the brake pedal. In my opinion these issues are definitely dangerous and can get someone seriously injured or fatalities could occur.”
