Recall 25V6890002,101 vehicles

Problem
Ford Motor Company (Ford) is recalling certain 2021-2023 Mustang vehicles repaired incorrectly under recall number 23V727.

As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 135, "Light Vehicle Brake Systems."
Risk
Without a low brake fluid warning light, the vehicle may be driven with low brake fluid, reducing braking performance and increasing the risk of a crash.
Fix
Dealers will update the body control module software, free of charge. Owner notification letters were mailed December 11, 2025. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25C55. Vehicle Identification Numbers (VINs) involved in this recall will be searchable on NHTSA.gov beginning November 17, 2025.

Recall 25V442000200,237 vehiclesopened after NHTSA action (ODI)

Problem
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.
Risk
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.
