Based on the Mazda3, the new CX-30 fills the gap between the CX-3 and CX-5 SUVs and competes with several compact and subcompact SUVs, including the Nissan Rogue Sport and Subaru Crosstrek. It is a bit more expensive than those peers, but brings a nicely finished interior and a dash of style. Unfortunately those assets are countered by a noisy engine and tight quarters.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for about 329,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2020 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.
