What stands behind each score for this car:
Owners have filed 306 complaints with NHTSA for this model-year, and engine is the most reported area with 83 of them (27%). There are 3 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 78/100 (good) from NHTSA recall campaigns and complaint density, adjusted for how many were sold so a popular model is not penalised for having more owners.
AVOIR scores its longevity 82/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2020 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.
