Electrical system: body control module/bcmReported October 10, 2025 · 2,101 vehicles affected
What is wrong
Ford Motor Company (Ford) is recalling certain 2021-2023 Mustang vehicles repaired incorrectly under recall number 23V727.

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 beginning November 17, 2025.

My vehicle, VIN [XXX], is subject to the federal safety agency 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 federal safety agency 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 federal safety agency and Ford recall website VIN lookup continues to show the recall as open. This discrepancy creates confusion regarding the status of the recall and whether Ford is actively notifying affected owners. I am concerned that my vehicle remains subject to a known safety defect without an available repair and request that the federal safety agency review Ford’s handling of Recall 25V455, the prolonged delay in providing a remedy, and the inconsistency between Ford’s customer-facing systems and the federal safety agency recall database.
