Recalls and investigations

3 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-402Jun 24, 2026
Power Train:Automatic Transmission

Ford Motor Company (Ford) is recalling certain 2018-2021 Navigator, Expedition, 2020-2021 Explorer, Lincoln Aviator, and 2021 F-150 vehicles. The transmission park pawl may engage while the vehicle is in motion, resulting in park system damage.

Risk and remedy
Risk: Park system damage may result in a vehicle rollaway, increasing the risk of a crash.
Remedy: Dealers will update the powertrain control module software, and inspect and replace any damaged transmission components as necessary, free of charge. Interim letters, notifying owners of the safety risk, were mailed July 10, 2026. Additional letters will be sent once the remedy is available, anticipated in April 2027. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 26S48. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on June 26, 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.

Transmission and drivetrain · model years 2011 to 2013

Unexpected transmission downshift. Closed oct 22, 2019, led to recall 19V-075.

NHTSA summary
The Office of Defects Investigation (ODI) opened an investigation based on consumer allegations of transmissions unexpectedly downshifting to a lower gear without input from the driver on model year (MY) 2011-2013 Ford F-150, Expedition and Navigator vehicles. ODI has received 455 unique reports related to the alleged problem that were not covered under a previous recall for this issue (16V-248).Expedition and Navigator complaint rates are lower than F-150 complaints. Of those 455 reports, 34.7% claimed that the rear wheels locked up when the transmission downshifted. There were 4 accident claims with no injuries. There are many instances where drivers report leaving their lane or the road because of this issue.In response to ODI's Information Request (IR) letter, Ford Motor Company (Ford) responded with 783 unique reports related to the alleged problem. There were 6 accident claims with 3 injuries. Ford also submitted 1206 warranty claims related to transmission downshifting failures. The failure can occur at any time, but typically at higher speed, and include symptoms such as sudden transmission downshifting, loss of speedometer, erratic shifting of transmission, and transmission stuck in one gear. The failures typically occur without warning and may result in the rear wheels momentarily locking up. The driver often had to fully stop the vehicle and restart it to get the vehicle to shift properly.On February 2nd, 2019 Ford notified ODI that it would conduct a safety recall

None of these investigations covers the 2018 model year.

What owners wrote

“When attempting to pass a slow moving vehicle on a 2 lane highway when driving up a hill the transmission failed to properly shift instead making a loud clunking and grinding sound before eventually managing to shift into a gear. This failure to shift properly meant that the vehicle was unexpectedly without power when trying to change lanes leading to a dangerous situation.”

Filed Dec 30, 2025

“Since November 2024 to date the transmission has reduced power when trying to accelerate thus being unsafe when trying to pull out into traffic. It also will not engage reverse thus again impeding when in traffic. It appears randomly. Verified software has been updated. Ford is saying complete transmission replacement is needed on a vehicle that is only 7 years old.”

Filed Oct 13, 2025

“Ford had to rebuild rear differential. The transmission failed, too. Both unacceptable especially at 62k miles and zero utility usage including trailering or 4wd.”

Should you keep driving it?

This page can't tell you that. 0 of 26 reports involved a crash and 1 people were hurt. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
