Mazda CX-9: Best and Worst Years by Complaints
Comparing the 13 Mazda CX-9 model years from 2008 to 2021 that have at least 25 NHTSA complaints, and allowing for the era and for how long each year has had to collect complaints, 2017, 2015, 2016 have the fewest complaints relative to a typical CX-9 year and 2012, 2010, 2011 have the most. This reflects NHTSA complaint data only.
This comparison uses only NHTSA complaints, recalls and investigations. It is not a reliability verdict: complaint counts are not adjusted for how many cars were sold, and complaints are unverified consumer reports. An open NHTSA investigation is shown separately; it is not a finding.
Fewer complaints than typical
Score 35 or lower: about 0.7× or less the weighted complaint rate of a typical CX-9 year.
More complaints than typical
Score 65 or higher: about 1.4× or more the weighted complaint rate of a typical CX-9 year, counting severe reports, recalls and mileage.
All CX-9 years compared
Score 0–100, where 50 is a typical CX-9 year: complaints relative to all vehicles of the same model year (which allows for the era and for time on the road), weighted for crashes, fires, injuries and recalls and for how early the problems appear. Model years 2008 to 2023 with at least 25 complaints are compared; newer years are too new to compare. Methodology
