MAZDA CX-9

The MAZDACX-9 appears in NHTSA's Office of Defects Investigation database with 1,785 consumer safety complaints and 14 safety recalls across 17 model years (2007–2023). That averages roughly 105 complaints per model year, but the distribution is almost never even — most nameplates concentrate their defect reports in a handful of cohort years tied to specific platform refreshes, supplier changes, or component redesigns.

Complaint volume on a nameplate alone is not a reliability verdict: a long-running bestseller will accumulate more filings than a low-volume niche model simply because more of them are on the road. What matters is the year-over-year shape and the component concentration — which the table below isolates for the CX-9 by showing complaint count, crash count, fire count, and NHTSA safety rating side by side for each model year. The filing-year histogram below the table shows whether complaints are still being submitted against this nameplate or whether the pattern has plateaued, an important distinction for used-car shoppers weighing older cohort years.

NHTSA has 21 investigation files tied to this model, with 1 currently open. Investigations precede recalls and signal that the Office of Defects Investigation is actively testing a theory about a specific component cluster. Together with the complaint-by-year breakdown and recall remedy status, they are the primary signals used by insurance actuaries, fleet managers, and used-vehicle appraisers when pricing MAZDACX-9 risk. Compare this nameplate against siblings in the same platform family to see whether a given defect pattern is model-specific or shared across the parent architecture.
