Model-level reading
What changes the warranty calculation
1,823 submitted complaints appear in the Mazda CX-5 file. They stretch across 11 model years, with the middle annual count at 133.
Report volume peaks at 507 for 2016. 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.
