Overview

2015 Mazda CX-9

The 2015 Mazda CX-9 offers a blend of family utility and Mazda's characteristic driving dynamics, but used shoppers must navigate its reliability record carefully. This three-row SUV is powered by a 3.7-liter V6 engine paired with a 6-speed automatic transmission, delivering adequate performance for its class. Its safety scores are generally strong, with a 4-star overall rating from NHTSA, though frontal crash protection is rated lower. However, the CX-9's appeal is tempered by a substantial number of Technical Service Bulletins (TSBs) and two critical recalls concerning the front strut assembly and Takata airbags. These issues, coupled with a 'Below Average' reliability verdict, suggest a need for diligent inspection and verification of past repairs.

Critical Failure Risk

Recalls have addressed potential loosening of front strut assembly mounting nuts and bolts, which could lead to steering knuckle separation. This poses a critical safety defect impacting steering control.

Early detection can help you avoid a $500-$1,500 repair.
