Reliability, what owners report, and what it costs to keep.
AVOIR's read: the reliability record is poor enough to outweigh everything else here.
Owners have filed 1,381 complaints with NHTSA about the 2013 Kia Optima, and it carries 9 recalls. These are owner allegations rather than confirmed defects, but the pattern of what people complain about is the most useful signal a used buyer has.

NHTSA lists 9 recall campaigns for the 2013 Kia Optima. 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.

What stands behind each score for this car:
Owners have filed 1,381 complaints with NHTSA for this model-year, and engine is the most reported area with 390 of them (28%). There are 9 recalls on record. Check any specific car against its VIN before buying.
AVOIR scores its reliability 42/100 (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 62/100, but that figure is an estimate built from the powertrain and the brand's record, not a measurement. A 2013 car has no 200,000-mile population to observe yet, so treat it as a prior rather than evidence.
AVOIR's read: skip, because the reliability record is poor enough to outweigh everything else here. Its overall ownership score is 65/100. Condition, mileage and service history still matter more than any score, so get a pre-purchase inspection on the specific car.
