6 recalls.

25V689000

Date: 2025-10-10. Systems: ELECTRICAL SYSTEM.

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."

Consequence: 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.

The low-pressure fuel pump may fail, which can result in an engine stall while driving.

Consequence: An engine stall increases the risk of a crash.

Remedy: Dealers will replace the low pressure fuel pump on super duty vehicles and update the powertrain control module (PCM) software on all other affected vehicles, free of charge.

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. (excerpt)

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
