Kestrel Take
The best-driving three-row SUV under $25,000 and one of the more interesting engines in the class — a 2.5L turbo tuned for torque rather than horsepower. First-year of a new generation, so check for the early software and infotainment fixes, but the mechanicals are sound.
What we checked
Partly reconciled against public records, 2026-09-11
NHTSA holds 99 owner complaints for the 2016 Mazda CX-9, and no recall campaigns.
A big number here usually means a lot of these were sold, not that it is a bad vehicle — popular models collect more complaints for the same rate of trouble. So the total on its own says little. What is worth reading is the shape of it. 64% of them are about one thing — the engine. That much concentration is a genuine pattern rather than background noise, and it is the first thing to check on any example you look at.
Not written up yet: the brakes (11 complaints). That group is in the public record and is not covered by the issues below. Treat it as something to ask about, not as absent.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
