2016 Mazda CX-9 problems: engine and transmission complaints and recalls

VERY HIGH COMPLAINT SIGNAL
74%
72 of 99 relevant owner complaints are about the engine, transmission or fuel system

74% of relevant owner complaints filed with NHTSA on the 2016 Mazda CX-9 are about the engine, transmission or fuel system. Well over half of everything owners reported is the drivetrain. That is a severe model-level pattern; every model year we track at this level has a documented failure behind it.

Worse than 94% of the 1,790 model years we track (2010–2023).

NHTSA data checked October 3, 2026

The VIN is on the listing, the driver’s door jamb, and the bottom of the windshield on the driver’s side.

Does the 2016 Mazda CX-9 have engine problems?

Owner complaints say yes, heavily, as a model-year pattern. 72 of 99 relevant complaints filed with NHTSA about the 2016 Mazda CX-9 concern the engine, transmission or fuel system (74%), and the largest group is filed under engine (61). For comparison, the 2015 scores 63% and the 2017 scores 80%. On a test drive, check for stalling, loss of power, rough idle, oil consumption or a check-engine light. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
