What stands behind each score for this car:
Owners have filed 300 complaints with NHTSA for this model-year, and electrical system is the most reported area with 44 of them (15%). There are 3 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 63/100 (average) 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 70/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2015 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: worth a look, because a solid ownership case with specific caveats below. Its overall ownership score is 72/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
