Avoid: the 2021 CX-30
The 2021 drew 101 complaints, more than twice any other CX-30 year, and the engine is the component owners name most. 39 describe a low-oil warning, a dipstick near empty or quarts added between changes; 8 of the 2021's complaints name the turbo engine.
11 more 2021 complaints mention the battery, most describing a drained battery or a car that would not start. Recall 21V101000 covers tire valves on 2021 CX-30s that may suddenly leak air.
NHTSA lists no recall for the oil consumption. Ask for the oil-change records and check the level yourself.

- 101 complaints, the most of any CX-30 year.
- 39 describe low oil.

Recall 23V275000 covers the ABS hydraulic unit on 2022–2023 CX-30s, which may be damaged and reduce braking.

What CX-30 Owners Say
Most CX-30 owners in these threads report oil changes and little else; the recurring complaints are about the transmission's low-speed behaviour, the 2021 turbo's oil use and early batteries.
In owners' words (paraphrased)
- Bought new: four years in, nothing but oil changes.
- 2020 FWD at 42,000 miles: no rattles; the transmission picks a tall gear on a gentle launch and whines a little.
- 2021 Premium AWD: the battery failed in 2022 and Mazda replaced it; flawless otherwise at 21,000 miles.
- 2021 turbo: still the low-oil problem, a failing trunk latch and a tow-in for overheating.
- 2022 at 25,000 miles: no buzzes or rattles, but the owner still dislikes the infotainment command wheel.
- A 2021 Premium owner: loves the car; the complaints they hear most are weak A/C and clunky low-speed shifting.

Reading CX-30 Complaint Numbers
NHTSA complaints are owner reports, not verified and not divided by sales. CX-30 totals are small, so a few dozen complaints decide the ranking; the 2021 stands out because 39 of its complaints describe the same fault.
The fault counts come from searching the words owners used, so they are a minimum. The 2026 has 5 complaints so far.
