NHTSA lists 2 recall campaigns for the 2024 Mazda CX-30. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.

Percentile ranks against other SUVs in the catalog.
What stands behind each score for this car:
Owners have filed 31 complaints with NHTSA for this model-year, and electrical system is the most reported area with 3 of them (10%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 85/100 (excellent) from NHTSA recall campaigns and complaint density. That figure is a raw complaint count, not yet adjusted for sales volume, so a high-volume model scores worse than it deserves.
AVOIR scores its longevity 83/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2024 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: buy, because it scores well across the board with no single weak engine. Its overall ownership score is 80/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
Sources: NHTSA recalls and complaints, EPA fuel economy, IIHS awards, and live market listings. A score describes a model-year, not the individual car in front of you. Get a pre-purchase inspection.
