NHTSA has received 29 owner complaints about the 2021 Kia Sorento, or 5.1 per year on the road — far fewer complaints than typical for a vehicle of its age (complaint index 0.12, where 1.00 is the average of all tracked vehicles). Among the 85 model-year 2021 vehicles we track, it ranks #10 for fewest complaints per year. Against other Kia models its rate is 86% lower; against other Midsize SUVs it is 90% lower.
Counts are normalized by time on the road, not by sales volume: a popular model generates more reports than a rare one, and complaints are not verified individually. How we count
Limited data: fewer than 30 complaints, so shares and indexes are unstable.
Complaints filed between 2022-02-18 and 2026-08-28. Median delay from incident to filing: 34 days.
