Mazda CX-30: Years to Avoid and Best Years (Engine & Transmission)
Mazda CX-30 problems by model year, from 192 owner complaints filed with NHTSA. For each year: the share of complaints about the engine, transmission or fuel system, how many there were, and the recalls.
Years to avoid: 2021 (54%, 52 drivetrain complaints) and 2020 (39%, 12 drivetrain complaints). 2 of the 4 Mazda CX-30 years we score have an elevated engine, transmission or fuel-system complaint share.
Best years on this measure: 2023 (26%) and 2022 (31%). 2023 and 2022 rest on fewer than 60 complaints, so treat them as provisional. A low share means owners complained about other things more than the drivetrain, not that nothing ever fails.
The sharpest change between consecutive years is from 2021 (54%) to 2022 (31%), down 23 points. The complaint pattern shifts at that year, so check which year the car in front of you is.
By raw volume, the 2021 drew the most drivetrain complaints (52 of 79 across the scored years). Volume also tracks how many were sold and how long they have been on the road, which is why the share, not the count, sets the verdict.
Engine and transmission complaint share, 2010–2023
Share of relevant owner complaints about the engine, transmission or fuel system. 33% is elevated, 40% high, 60% very high. A dash means too few complaints to score.
