Mazda CX-9 Best and Worst Years by Owner Complaints
We rank Mazda CX-9 model years by the number of owner complaints filed with NHTSA, from fewest to most. Complaint counts aren't failure rates: years that sold more cars, or that are older, can show more reports. We rank only model years at least five years old, because newer ones are still collecting reports. Among settled years shown, the 2020 drew the fewest (19) and the 2012 the most (221).

What the numbers can't tell you
- Sales volume. NHTSA publishes no sales figures with complaints, so a popular year draws more reports even if each car is no worse.
- Recent years are under-counted. Owners file reports for years after purchase; the newest model years will keep growing.
- The individual car. Maintenance, mileage and repairs matter more for one used car than any model-year average. Get a pre-purchase inspection and check open recalls by VIN.
Mazda CX-9 years FAQ
Which Mazda CX-9 year has the fewest complaints?
Among the model years shown whose counts have settled, the 2020 has the fewest owner complaints filed with NHTSA (19). That is a count of reports, not a measure of reliability.
Does fewer complaints mean a more reliable car?
Not necessarily. Complaint counts depend on how many cars were sold, how old they are and how many owners file reports. Use them to spot patterns worth asking about, alongside recalls, crash tests and a pre-purchase inspection.
Are there Mazda CX-9 years to avoid?
No model year is officially one to avoid. By owner complaints to NHTSA, the settled years with the most reports are the 2012, 2010 and 2008 models, and across all years the most-reported problem area is the service brakes. Compare those years with the ones that drew the fewest reports, then check any specific car for open recalls by VIN and get a pre-purchase inspection.
What is the most common Mazda CX-9 problem?
Across the model years shown, owners most often report problems with the service brakes (448 of 1,489 complaints list it). Each model-year report breaks the complaints down by component.
How many recalls does the Mazda CX-9 have?
NHTSA lists 13 recall campaigns covering the Mazda CX-9. See every one, with official wording and repair rates, on the Mazda CX-9 recall page.
Why are newer years left out of fewest and most?
Owners keep filing complaints for years after a car is sold. We mark the two newest model years as still collecting reports, and we only rank years that are at least five years old.

Processing
- Complaints are counted per component. One complaint can list several, so component totals add up to more than the total.
- Fuel cost = miles per year ÷ EPA combined mpg × EIA weekly price for your region.
Limitations
- Complaint counts are owner reports, not verified findings or failure rates. There is no sales denominator.
- Recall campaigns are listed for the model year. Only NHTSA and the automaker know whether a specific car was repaired.
- Recent model years are still collecting reports.
