Kia EV9: which model years draw the most owner complaints?

260 complaints filed with NHTSA about the Kia EV9, model years 2024 to 2026. No model year stands out for the engine or transmission against the others. Counts of unverified owner reports, compared only with other years of the same model; not failure rates.

Complaints by model year

"Stands out" = 40 or more complaints naming that system and at least twice the model's quiet (lower-quartile) year, or twice the share seen across every vehicle of that model year. Newer years have had less time on the road. "Quiet" ranks only years with 7+ years on the road and 20+ complaints. NHTSA data through November 2026.
