Mazda CX-30 by Model Year: Problems, Recalls and MPG

Every Mazda CX-30 model year since 2020: EPA fuel economy, NHTSA recalls, owner complaints and crash tests.

Data: US EPA and NHTSAUpdated Sep 27, 2026

Every model year since 2020 in one place: EPA fuel economy, NHTSA recalls, owner complaints and crash test ratings. The best fuel economy rating, 29 mpg combined, arrived in 2023.

Complaints in each year's first three years

Model years ranked by owner complaints filed with NHTSA in their first three years (model year Y: filed by the end of Y+2), so every year is measured over the same time on the road. Years without three full years of data, and launch or final years with very few sold, are left out. Counts are not adjusted for how many were sold.

Questions

Which Mazda CX-30 years have the most problems?

A typical Mazda CX-30 year drew only 18 owner complaints in its first three years (the range is 14 to 68), too few to rank the years fairly. The 2024, 2025, and 2026 are not ranked yet: they have had fewer than three full years on the road.

Which Mazda CX-30 years have the most recalls?

The 2020 has the most safety recalls in NHTSA's file (3), then the 2024 (2). A recall can cover a problem that affects only a few cars, so open a year's page to see what each one covers. No recall for 2020 to 2026 models tells owners not to drive the car or to park it outside.

What are the most common Mazda CX-30 problems?

Of the 252 owner complaints NHTSA lists for 2020 to 2026 models, the areas named most are engine (27%), electrical system (19%), and forward collision avoidance (14%). One complaint can name more than one area. The recalls and problems page for each year breaks this down further.

Which Mazda CX-30 year has the best MPG?

The best EPA fuel economy is 29 mpg combined, first reached by the 2023 gas version.
