BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Summary: Ford Motor Company (Ford) is recalling certain 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. Due to a poor electrical connection, the rearview camera may intermittently display a blank or distorted image. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."

Safety Consequence: Reduced rearward visibility can increase the risk of a crash.
Manufacturer Remedy: Ford will notify owners, and dealers will replace the rearview camera, free of charge. The recall began November 17, 2020. Remedy became available on February 1, 2021. Owner notification letters were mailed on February 1, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20C19.
NHTSA Campaign #21V011000Reported: 15/01/2021

POWER TRAIN:DRIVELINE:DRIVESHAFT

Summary: Ford Motor Company (Ford) is recalling certain 2020-2021 Edge, 2020 Lincoln Nautilus and Ford Escape and 2021 Lincoln Corsair and Ford Bronco Sport vehicles. An inadequate amount of lubricant in the rear drive unit may cause seizure of the rear drive axle.

Safety Consequence: If the rear drive unit seizes, there may be a loss of drive and/or a loss of vehicle control, increasing the risk of a crash.
Manufacturer Remedy: Ford will notify owners, and dealers will check the rear drive unit lubricant level. Axles found to have lubricant at the minimum level will be filled to the full level. Axles found to be below the minimum lubricant fill level will be replaced, free of charge. This recall began March 12, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 21S02.
NHTSA Campaign #20V414000Reported: 17/07/2020

SEATS:FRONT ASSEMBLY:POWER ADJUST

Summary: Ford Motor Company, Inc. (Ford) is recalling certain 2016-2018 Lincoln MKX and 2019-2020 Nautilus vehicles equipped with 16-way electric tilt seats. The seat cushion frame edge may contact the wire harness when the seat occupant uses the tilt function of the seat, potentially damaging one or more wires within the harness, which can result in either inadvertent deployment of the air bag or nondeployment of the air bag in the event of a crash.

Safety Consequence: An air bag that deploys inadvertently increases the risk of a crash. An air bag that does not deploy in the event of a crash increases the risk of injury.
Manufacturer Remedy: Ford will notify owners, and dealers will install protective flocking tape onto the exposed edge of the 16-way seat cushion frames, and inspect the wire harness for damage, and repair or replace it as needed, free of charge. This recall began August 12, 2020. Owners may contact Ford/Lincoln customer service at 1-866-436-7332. Ford's number for this recall is 20S37.
NHTSA Campaign #25V442000Reported: 27/06/2025

BACK OVER PREVENTION:SOFTWARE

Summary: Ford Motor Company (Ford) is recalling certain 2018-2022 Transit Connect, 2019-2020 MKZ, MKX, Edge, Continental, F-150, Nautilus, Fusion, 2019-2023 Ranger, Mustang, 2020-2021 EcoSport, Expedition, Navigator, 2020-2022 Escape, F-250 SD, Corsair, 2020-2023 Aviator, Transit, 2020-2024 Explorer, 2021-2024 Bronco Sport, and 2022-2024 Maverick vehicles. A software error may cause the rearview camera to display a blank image, or the image may remain on the display after the backing event has ended.

Safety Consequence: A rearview camera that displays a blank image can reduce the driver's view behind the vehicle. A rearview image that continues to be displayed after the vehicle is shifted out of reverse may distract the driver. Both of these situations can increase the risk of a crash.
Manufacturer Remedy: Dealers will update the rearview camera software, free of charge. Owner notification letters were mailed September 4, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S72.
NHTSA Campaign #20V550000Reported: 10/09/2020

POWER TRAIN:AUTOMATIC TRANSMISSION

Summary: Ford Motor Company (Ford) is recalling certain 2019-2020 Edge, Transit Connect and Lincoln MKX and 2020 Escape and Lincoln Corsair vehicles. The start/stop accumulator endcap may have missing or loose bolts.

Safety Consequence: Missing or loose bolts on the start stop accumulator endcap could result in a transmission fluid leak and may progress to a loss of transmission function. A transmission fluid leak in the presence of an ignition source may increase the risk of fire.
Manufacturer Remedy: Ford will notify owners, and dealers will replace the start/stop accumulator, free of charge. The recall began September 23, 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 20S49.
