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

Does the 2019 Mazda CX-9 have engine problems?

Owner complaints say yes, as a model-year pattern. 25 of 53 relevant complaints filed with NHTSA about the 2019 Mazda CX-9 concern the engine, transmission or fuel system (47%), and the largest group is filed under engine (23). For comparison, the 2018 scores 68%. 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.
