Recalls and investigations

4 recalls on the transmission and drivetrain cover the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.

26V-375Jun 9, 2026
Power Train:Automatic Transmission:Control Module (Tcm/Pcm/Tecm)

Ford Motor Company (Ford) is recalling certain 2018 F-150 vehicles previously repaired incorrectly under recall number 17V669. Quickly moving the shift lever from Park to Drive may cause a loss of gear indication on the instrument cluster display and a momentary selection of an unintended gear, such as Reverse or Neutral.

Risk and remedy
Risk: Unintended gear selection may cause the vehicle to move in an unexpected direction, increasing the risk of crash or injury.
Remedy: Dealers will update the powertrain control module software, free of charge. Owner notification letters were mailed July 9, 2026. Owners may contact customer service at 1-866-436-7332. Ford's number for this recall is 26S42. Vehicle Identification Numbers (VINs) involved in this recall will become searchable on NHTSA.gov on July 6, 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.
18V-214Apr 4, 2018
Power Train:Automatic Transmission:Gear Position Indication (Prndl)

Ford Motor Company (Ford) is recalling certain 2018 F-650 and F-750 vehicles equipped with 6-speed automatic transmissions and 2018 Ford F-150 and Expedition vehicles equipped with 10-speed automatic transmissions (excluding Expedition vehicles with a Rotary Gear Shift Dial on the console). The gear shift cable clip may not be properly seated, allowing the transmission to be in a different gear than indicated by the gear shift lever position.

Risk and remedy
Risk: If the gear shift cable clip becomes unseated or dislodged, the gear shift lever position may indicate that the transmission is in 'Park' when it may be in a different gear. Additionally, despite selecting 'Park', if the parking brake is not applied before the vehicle is exited, the vehicle may roll. Either scenario increases the risk of a crash.
Remedy: Ford will notify owners, and dealers will inspect the shift cable locking clip and properly seat it, if necessary, 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 the recall is 18S10.
17V-669Oct 23, 2017
Power Train:Automatic Transmission:Lever And Linkage:Column Shift

Ford Motor Company (Ford) is recalling certain 2018 F-150 vehicles equipped with a 3.3L engine, a 6-speed transmission and a column mounted shift lever. Quickly moving the shift lever from Park to Drive may cause a loss of gear indication on the instrument cluster display and a momentary selection of an unintended gear, such as Reverse or Neutral before the vehicle achieves Drive function.

Risk and remedy
Risk: Unidentified or unintended gear selection may cause the vehicle to move in a way that was not intended by the driver, increasing the risk of crash or injury.
Remedy: Ford will notify owners, and dealers will reprogram the powertrain control module, free of charge. Owners may contact Ford Customer Service at 1-866-436-7332. Ford's number for this recall is 17S35.

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

“Our vehicle has 79,500 miles and the transmission is slipping between 2nd and 3rd, and causing rpm surging. We had a diagnostic done and need the cdf drum replaced with the newly designed part as the current part has a defect. This is apparently a known issue and should be a recall so the defective part can be replaced. This will cost me 7k to 9k to either rebuild or replace my transmission.”
