The recall affects certain 2024–2026 Ford Mustang models produced between September 7, 2022, and June 9, 2026. The issue was reported by the National Highway Traffic Safety Administration (NHTSA) under recall number 26V547, which identifies the problem as a possible failure in engine compartment wiring harness ground connections.
The safety action comes after regulators determined that damaged electrical connections could affect vehicle operation and visibility. According to NHTSA, a loss of drive power while driving, or the loss of headlights and windshield washing functions, may increase the risk of a crash.
A Wiring Harness Defect Led to the Mustang Recall
The affected vehicles may have engine compartment wiring harness ground eyelet terminals that can fracture over time. According to recall documents submitted by Ford, heat shrink adhesive used on the eyelets may contribute to bending stress, reducing the durability of the connections under normal vehicle vibration.
Depending on which ground connection is affected, the vehicle may experience a loss of motive power or the failure of several functions. These include the left and right headlights, windshield washer fluid pump, air conditioning system, and engine cooling fan.
Ford’s investigation began after a durability test failure involving broken eyelets on a Mustang test vehicle. According to the company’s filing with NHTSA, engineers identified that the condition could also exist in vehicles already in production.
Ford reported eight warranty claims related to the issue between October 18, 2024, and August 4, 2026, with no vehicle owner questionnaires, accidents, or injuries connected to the condition. The company identified the affected population through vehicle assembly records.
The repair involves replacing the engine compartment wiring harness ground terminals with redesigned components. Dealers will complete the repair free of charge. Interim owner notification letters were scheduled to be mailed between August 31 and September 4, 2026, while additional letters about the available remedy are expected later.
Ford Also Announced Separate Recalls Involving Other Vehicles
Alongside the Mustang recall, Ford issued another recall affecting more than 10,000 vehicles from the 2026 model year. According to recall documents, the affected vehicles include the Bronco, Bronco Sport, Explorer, Ranger, and Mustang models equipped with the 2.3-liter EcoBoost engine.
That recall concerns possible piston failures caused by a manufacturing issue. The documents state that a supplier machining problem may have created cracks in the piston dome, which could result in engine failure and a loss of drive power.
Ford said it was aware of 22 engine failures at company facilities and two field failures that could be related to the piston concern as of August 12, 2026. Dealers will inspect affected vehicles, and engines with pistons showing the identified defect will receive replacement long blocks. The Mustang wiring recall remains focused on the electrical system issue identified by NHTSA. Owners can check whether their vehicle is included through the NHTSA recall database using their vehicle identification number.
