Mazda CX-30 Reliability by Year

Every CX-30 model year from 2020 to 2025, scored on reported failures weighted against how many were sold — and ranked against every other Compact SUV of the same year.

The short answer

Best model year
2023
#3 of 42 that year
Year to avoid
2021
#27 of 35 that year
Latest scored
2025
#23 of 42

Across 6 scored model years the CX-30 sits close to its class average on both counts. The spread between years is what matters: 2023 is its strongest, 2021 its weakest.

Every model year, scored

Longer bar is better. Rank is against every Compact SUV sold that same model year.

The line held a middling position through 2021, then moved to strong from 2022 on. Recent years have been slipping. This 2025 car falls in a strong stretch.

What tends to break

All 12 systems, measured against the class average for each model year.

Every CX-30 model year is scored across 12 separate systems — engine, transmission, brakes, electrical, steering and suspension, structure, interior, and five more. Each system is compared against how often that same system fails on the average Compact SUV of the same year, so a common failure is judged against how common it is everywhere else.

Across the last three model years (2023–2025), the trouble concentrates in one place: interior & safety. That system draws issue reports more often than the same system on the average Compact SUV of its year — which changes what you should be inspecting before you buy.

Where does this data come from?

Failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes so a high-volume model is not penalised for selling well, then benchmarked within segment and model year.

How this was built. Scores derive from failure reports filed with NHTSA — submitted by vehicle owners and repair shops alike — weighted against US sales volumes and benchmarked within segment and model year. We measure two separate things: Fix Frequency — how often a vehicle needs fixing — and Fix Severity — how costly those fixes are. These figures describe a model line, not the specific vehicle in front of you; trim, mileage and service history still decide an individual car.
