Model-level reading
What changes the warranty calculation
2,334 submitted complaints appear in the Ford Mustang file. They stretch across 11 model years, with the middle annual count at 175.
Report volume peaks at 434 for 2015. Without registration counts or equal vehicle age, the peak cannot serve as a defect ranking.
Among the matching repair categories, Engine replacement or major internal repair tops the parts midpoints at $7,000. That is the system I would locate in both the factory warranty and any proposed service contract.
