Percentile ranks against other SUVs in the catalog.
What stands behind each score for this car:
Owners have filed 27 complaints with NHTSA for this model-year, and engine is the most reported area with 4 of them (15%). There are 2 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 88/100 (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 81/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2025 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.
