Best and Worst Kia Niro Years: What the NHTSA Data Shows
Across the 6 Kia Niro model years from 2017 to 2022 that have NHTSA data, the typical year has about 73 owner complaints on file. These are the extremes:
Fewest owner complaints
Complaint counts are unverified owner reports to NHTSA and rise with how many cars were sold and how long they have been on the road, so treat them as a pointer for what to inspect, not a reliability score. Model years after 2022 are left out because they have had little time to accumulate reports. Always check a specific car by VIN at nhtsa.gov/recalls.
