What stands behind each score for this car:
Owners have filed 230 complaints with NHTSA for this model-year, and unknown or other is the most reported area with 34 of them (15%). There are 4 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 76/100 (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 78/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2024 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 77/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
