Hyundai Kona vs Mazda CX-30: Reliability Compared

A slight edge goes to the Mazda CX-30 over the Hyundai Kona, because owners file far fewer complaints about it. The Kona draws 13.4 complaints per 10,000 sold against 5.7, with more engine and transmission failures. Both still rate good overall.

How Do the Hyundai Kona and Mazda CX-30 Generations Compare?

Most used cars you will see from either maker belong to a first generation. For the Kona, that generation covered model years 2018 to 2023 and got a facelift for 2021. It includes the weakest years, 2019 and 2020. A second generation began with the 2024 model year. The CX-30 has one generation, which the data lists as 2020 to 2024. Its early years, 2020 and 2021, carry the most complaints. The newest years of both models have had less time to gather complaints, so a thin record there is not a guarantee.

Verdict

The Mazda CX-30 is more reliable than the Hyundai Kona, scoring 67/100 vs 65/100.

Reliability gives the Mazda CX-30 a slight edge, and both sit in good standing. The deciding fact is the complaint rate. Owners file 5.7 complaints per 10,000 sold for the CX-30 against 13.4 for the Kona. The Kona also has more recalls and a heavier engine and transmission problem list, including power loss while driving. The CX-30 has serious issues of its own, mainly emergency braking and airbags, so the gap is real but not large.

What Are the Common Problems With the Hyundai Kona and Mazda CX-30?

Mechanical failures dominate the Hyundai side. Kona owners report power cutting out at highway speed, cars that will not restart, coolant leaks, transmissions failing at low mileage, and a horn that keeps failing. Engine, electrical, speed control and brake complaints all include crashes. Adaptive cruise control crash reports, including a car accelerating while parking, appear only for the Kona. The CX-30 has fewer complaints, and its crash-linked areas are brakes and air bags. Emergency braking can stop the car with nothing ahead, and air bags have deployed with no crash. Its engine complaints are mostly low oil warnings, with no crashes and no engine damage reported.

Best years to cross-shop: The 2024 Hyundai Kona scored 68/100 and the 2024 Mazda CX-30 scored 68/100 — the strongest shared model years that have been on the road for at least two years, where available.

Who Should Buy the Hyundai Kona vs the Mazda CX-30?

Pick the CX-30 if you want the lower chance of trouble. Owners file fewer than half as many complaints per car sold, and its engine reports center on a low oil light rather than stalling. Target 2024 or later within the first generation, and avoid 2020 and 2021, its weakest years. Check the oil level often, and ask whether any open airbag recall remains unfixed. Pick the Kona if its fit or price suits you better, but shop more carefully. Avoid 2019 and 2020, the weakest years. The 2018 ranks among the strongest, though it is the oldest. Newer years such as 2025 have had less time to collect complaints, so do not read their clean record as proof. On any Kona, ask about engine cooling repairs and transmission behavior. Test adaptive cruise control on a highway. Be extra cautious with a Kona Electric that has a history of a dead 12V battery.
