2018 Mazda CX-3 — Should You Buy One?
Typical asking price: $12,000–$17,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.
Kestrel Take
Really a tall, sporty hatch, the CX-3 drives better than any subcompact crossover has a right to, with a durable SkyActiv 2.0L and no turbo or CVT. The trade-off is a tight rear seat and small cargo hold. If you value how a small car drives over how much it hauls, it's a gem — buy the maintained one and enjoy.
What we checked
Reconciled against public records, 2026-09-11
NHTSA holds 10 owner complaints for the 2018 Mazda CX-3, across 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 engine at 20%. 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.
Looked at and set aside: back over prevention (2) — 2 backup-camera complaints; often a software update, worth testing on the test drive.
Counts come from the NHTSA complaint and recall database — free, public, and worth checking yourself.
