Percentile ranks against other SUVs in the catalog.
What stands behind each score for this car:
Owners have filed 397 complaints with NHTSA for this model-year, and engine is the most reported area with 95 of them (24%). There are 4 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 53/100 (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 66/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2011 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: be careful, because the numbers are mixed and the complaint record is worth reading before you commit. Its overall ownership score is 63/100. 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.
