NHTSA lists 6 recall campaigns for the 2012 Hyundai Sonata Hybrid. Recalls are free to have fixed at a franchised dealer regardless of who owns the car now, but only if they were never done, so check the VIN of the specific car rather than trusting the model.
Hyundai Motor America (Hyundai) is recalling certain 2015-2016 Veloster, 2012 Santa Fe, 2011-2013 Sonata Hybrid, and 2016 Sonata Hybrid vehicles. The connecting rod bearings inside the engine may wear prematurely, which over time can result in engine damage.

What stands behind each score for this car:
Owners have filed 154 complaints with NHTSA for this model-year, and engine is the most reported area with 44 of them (29%). There are 6 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 48/100 (below 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 64/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2012 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 66/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
