What stands behind each score for this car:
Owners have filed 116 complaints with NHTSA for this model-year, and unknown or other is the most reported area with 27 of them (23%). No recalls are on record for it.
AVOIR scores its reliability 79/100 (good) 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 78/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2017 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 78/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
