Overview
- The agency upgraded the inquiry to an engineering analysis covering about 135,000 Ford Fiesta, Focus, and EcoSport cars with 1.0L engines after receiving 355 incident reports.
- Preliminary teardown work found timing‑belt material can shed debris that clogs the mesh oil‑pump pick‑up screen, which can sharply lower oil pressure and cause loss of motive power or engine seizure.
- NHTSA’s data show an average failure at roughly 70,000 miles and that 98% of incidents occurred before the 150,000‑mile replacement interval recommended by Ford.
- Ford told regulators in June it will run a global non‑safety customer program that shortens the timing‑belt service interval to 100,000 miles or six years and offers some reimbursements, but U.S. coverage and a recall have not been announced.
- Owners report costly engine damage and sudden on‑road power loss, and the engineering analysis is the formal step that could allow NHTSA to require a safety recall if the defect is confirmed.
