ELECTRICAL SYSTEM:BODY CONTROL MODULE/BCM

25V689000 · October 10, 2025

The defect
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."
The 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.
The 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/PROPULSION SYSTEM
My vehicle, VIN [XXX], is subject to NHTSA Recall 25V455 (Ford Recall 25S75) involving a defective low-pressure fuel pump that may cause engine hesitation, loss of power, or engine stalling. This recall was announced in July 2025 and remains open on the NHTSA VIN lookup as of June 2026. More than eleven months have passed since the recall was announced, and Ford has not provided a repair remedy for my vehicle. I believe this is an unreasonable delay for a safety-related defect. In addition, the recall previously appeared in the FordPass application associated with my vehicle but no longer appears there, even though both the NHTSA and Ford recall website VIN lookup continues to show the

A complaint is one owner's account and has not been verified by NHTSA or by us. A vehicle with more complaints is not necessarily worse: models that sold in larger numbers collect more of them. How this is counted.
