Overview
- Federal regulators published the recall covering 148,663 2024–2026 Mustangs built between Sept. 7, 2022, and June 9, 2026, and owner notification letters began going out around Aug. 31–Sept. 4.
- NHTSA and Ford say adhesive-lined heat‑shrink used on engine wiring can intrude into metal ground eyelets, bend them during assembly, and create stress points that can fracture from vibration.
- A fractured ground eyelet can sever an electrical connection and cause sudden loss of drive power or disable the headlights, windshield washer, air conditioning, or engine cooling fan, with drivers sometimes seeing a check-engine light or warnings first.
- Dealers were notified of the recall on Aug. 28, will perform the repair free of charge, and Ford expects redesigned ground terminals to be available for replacement around March 2027, leaving owners to wait for the definitive fix.
- Ford and NHTSA estimate roughly 1% of affected cars may contain the defect; Ford reported eight related warranty claims and no crashes or injuries as of mid‑August, and the company is concurrently managing a separate recall over cracked pistons in some 2026 models.
