Kestrel Take
The enthusiast's midsize sedan and one of the least troublesome cars in this whole guide. Skyactiv is a conventional port-and-direct-injected engine with a conventional automatic — no CVT, no dual clutch, no turbo. The main enemy is rust in salt states.
What we checked
Partly reconciled against public records, 2026-09-25
NHTSA holds 77 owner complaints for the 2016 Mazda Mazda6, and 1 recall campaign.
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. The largest single group is the brakes at 16%. That is notable without being overwhelming — worth checking, not worth panicking about.
One recall campaign covers this model year. Recalls are repaired free, for any owner, with no time limit on most safety campaigns — but only if someone books it in. Ask the seller to show it was done, or have any dealer check the VIN; it takes them a couple of minutes and costs nothing.
Not written up yet: the brakes (12 complaints), the transmission and drivetrain (11 complaints). Those groups are in the public record and are not covered by the issues below. Treat them as something to ask about, not as absent.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
