What stands behind each score for this car:
Owners have filed 34 complaints with NHTSA for this model-year, and electrical system is the most reported area with 6 of them (18%). There are 2 recalls on record. Check any specific car against its VIN before buying.
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.
