2024–2026 Ford Mustang recall: wiring can cut drive power

Ford is recalling 148,663 potentially affected 2024–2026 Mustangs because engine-compartment wiring ground connections may fracture. Depending on the connection, the fault can cause loss of drive power, headlights, windshield-washer operation, air conditioning or engine-cooling-fan function. NHTSA identifies the campaign as 26V547000.

What the official recall record says

Ford Mustang: wiring harness ground terminals

Dealers will replace the engine-compartment wiring harness ground terminals at no charge. NHTSA’s current record says interim safety letters were mailed September 5, 2026. The reviewed sources describe the remedy as not yet available, but give different forecasts: the NHTSA record anticipates March 2027, while Ford’s September interim owner letter says December 21, 2026 or earlier. Owners should confirm the current repair schedule with Ford; neither forecast confirms present availability.

Official record

• NHTSA recall ID: 26V547000
• Vehicles listed: Ford Mustang (2024–2026)
• Potentially affected: 148,663
• Components: ELECTRICAL SYSTEM:WIRING
• Report received: August 25, 2026
• Owner notification: Interim safety letters were mailed September 5, 2026. A further letter will announce remedy availability; reviewed official sources give conflicting forecasts, described above.
• Defect: Ford Motor Company (Ford) is recalling certain 2024-2026 Mustang vehicles. The engine compartment wiring harness ground connections may fracture and result in a loss of drive power, or a loss of function in the windshield washing system, headlights, air conditioning, or engine cooling fan. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) numbers 108, “Lamps, Reflective Devices, and Associated Equipment,” and 104, “Windshield Wiping and Washing Systems.”
• Safety consequence: Loss of drive power or reduced visibility from inoperative headlights or windshield washers can increase crash risk.
• Remedy: Dealers will replace the engine-compartment wiring harness ground terminals free of charge. NHTSA reports interim letters mailed September 5, 2026 and anticipates remedy availability in March 2027; Ford’s September interim letter instead forecasts December 21, 2026 or earlier. The reviewed sources do not confirm an available remedy. Owners may contact Ford at 1-866-436-7332 and reference 26C40.

What owners should do next

Contact Ford at 1-866-436-7332 and reference 26C40 to confirm the current remedy timetable. Ford’s interim letter says another notice will tell owners when to schedule the free repair. Keep the interim notice and follow vehicle-specific guidance from Ford or an authorized dealer.

Mustang owners should also review the separate wiper and washer recall and check each campaign independently by VIN.

Our guide to using NHTSA recall information explains why confirming campaign coverage, remedy availability and repair completion are separate steps.

Use the official NHTSA recall lookup with your VIN to check individual recall status. A model-year listing alone does not confirm that a specific vehicle is affected or still needs repair.
