Mazda CX-9 years to avoid
Across the 2016–2019 Mazda CX-9, the 2018 model year drew the most owner complaints to NHTSA: 126, about 2.1× the 61 median of the other three model years with enough complaints to compare. The most-reported components that year were the engine and the electrical system. The 2019 drew the fewest of the years with enough complaints to compare, at 53. NHTSA holds fewer than 40 complaints for 2015, 2020, 2021 and 2022, too few to read as a quiet year rather than a gap in the records. Separately, the 2015, 2018 and 2019 each carry the most recall campaigns, 2. Complaint volume and recall campaign counts also reflect how long a model year has been on the road and how many were sold, so they rank years within this model rather than measuring build quality.
The 2018 CX-9 is the outlier of the 2016–2019 Mazda CX-9, with 126 complaints against the model's 80 median.
Every CX-9 model year, ranked
Every CX-9 model year NHTSA holds records for, most complaints first. Counts are NHTSA records as of 2026-09-15; recall campaigns and complaints are counted separately because a recall is the manufacturer acting and a complaint is an owner reporting. Years with enough on record have a page of their own.

- A higher count is not proof of a worse car. Complaint volume rises with sales volume and with years on the road.
- The comparison is between years of the CX-9 only. It says nothing about how the CX-9 compares with other models.
- NHTSA publishes owner reports without verifying them. A complaint is an allegation, not a defect finding.
- Recall campaigns cover production ranges. Only a VIN lookup shows whether one vehicle is included and whether the work was done.

Mazda CX-9 year-by-year questions
Which Mazda CX-9 year should I avoid?
Across the 2016–2019 Mazda CX-9, the 2018 model year drew the most owner complaints to NHTSA: 126, about 2.1× the 61 median of the other three model years with enough complaints to compare. The most-reported components that year were the engine and the electrical system. The 2019 drew the fewest of the years with enough complaints to compare, at 53. NHTSA holds fewer than 40 complaints for 2015, 2020, 2021 and 2022, too few to read as a quiet year rather than a gap in the records. Separately, the 2015, 2018 and 2019 each carry the most recall campaigns, 2. Complaint volume and recall campaign counts also reflect how long a model year has been on the road and how many were sold, so they rank years within this model rather than measuring build quality.
Which Mazda CX-9 year is the safest bet?
Of the 2016–2019 Mazda CX-9, the 2019 drew the fewest owner complaints to NHTSA — 53, against the model's 80 median. Years NHTSA holds fewer than 40 complaints for (2015, 2020, 2021 and 2022) are left out: too few reports is a gap in the records, not a quiet year. Newer years have had less time on the road, which lowers their count on its own, so treat this as a starting point and check the individual VIN.
Do complaint counts mean the Mazda CX-9 is unreliable?
No. NHTSA complaints are unverified owner reports, and the count rises with how many vehicles were sold and how long they have been on the road. They are useful for comparing years of the same model — which is what this page does — not for ranking one model against another.
How do I check a specific CX-9?
Take the 17-character VIN from the windshield or driver-door label and run it through NHTSA's free recall lookup. That reports open campaigns for that exact vehicle, including whether the repair is still outstanding. A model-year page cannot tell you that.
