2021 Ford Mustang recalls (6)
NHTSA campaigns for the 2021 Ford Mustang, all trims.
ELECTRICAL SYSTEM:BODY CONTROL MODULE/BCMOct 9, 2025 NHTSA 25V689000 · 2,101 vehicles
Ford Motor Company (Ford) is recalling certain 2021-2023 Mustang vehicles repaired incorrectly under recall number 23V727. The brake fluid level sensor may not activate the visual warning indicator when the brake fluid is low. 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.
Remedy: 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.
FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMPJul 6, 2025 NHTSA 25V455000 · 850,318 vehicles
Ford Motor Company (Ford) is recalling certain 2021-2023 Bronco, Explorer, Lincoln Aviator, F-250 SD, F-350 SD, F-450 SD, F-550 SD, 2021-2022 Lincoln Navigator, Mustang, F-150, and 2022 Expedition vehicles. The low-pressure fuel pump may fail, which can result in an engine stall while driving.
Risk: An engine stall increases the risk of a crash.
Remedy: The remedy is under development. Interim notification letters notifying owners of the safety risk were mailed July 16, 2025. Second letters will be sent once the remedy is available, anticipated 2nd Quarter 2026. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 25S75.
BACK OVER PREVENTION:SOFTWAREJun 26, 2025 NHTSA 25V442000 · 200,237 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.
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.
