Research Context
The 2021 Mazda CX-30 page works best as a research starting point. Complaint totals show how much owner-reported activity exists, while recalls and investigations help show whether any of that activity turned into formal safety action.
Because this is a newer-era vehicle page, it usually helps to compare this year against nearby model years before deciding whether a complaint pattern looks isolated or persistent. On this page, the most prominent complaint area is engine with 34 reported complaints.
Best Research Moves
- Use the complaint log to understand what owners were actually reporting instead of relying only on the raw complaint total.
- Review the recall section even if the total is smaller, because a limited number of recalls can still point to meaningful safety actions.
- This page is primarily a complaints-and-recalls research surface, so compare nearby model years before treating the complaint total as a standalone verdict.
Key Takeaways
- The 2021 Mazda CX-30 currently shows 2 NHTSA recalls listed on this page and 94 owner-reported complaints.
- This page currently shows no linked NHTSA investigations.
- This page reflects complaint volume, recall history, and NHTSA test data, but it does not diagnose causes or rank reliability by itself.
- Safety data currently shows 5/5 overall NHTSA safety rating.
- The most frequently reported complaint categories on this page are engine (34), visibility/wiper (8), unknown or other (5).

How to Interpret This Page
This page combines three types of NHTSA data: recall campaigns (official manufacturer or government actions), owner complaints (unverified consumer reports), and crash test ratings (where available). A vehicle with many complaints is not necessarily less reliable — complaint volume correlates with sales volume and vehicle age. Recalls indicate identified defects, not overall quality. To compare this model year with others, use the year navigation in the sidebar or return to the model overview page.
If you are researching a used vehicle, start with the complaint categories, compare them against the recall list, and then check nearby model years to see whether the same issue profile repeats. That usually produces a better buying or research signal than treating the raw complaint total as a standalone safety ranking.
