2016 Kia Optima problems
What owners reported to NHTSA, at what mileage, and every safety recall for this model year.
- Complaints are unverified owner reports. NHTSA does not confirm each one.
- No denominator: popular cars get more complaints. Counts are not failure rates; a best-seller will show more reports than a rare model.
Most reported problems
Complaints by component. One complaint can name more than one component, so these add up to more than 759.
When problems show up
Reports by odometer reading at the time of the problem, top components. Each bar is a 25,000-mile band, labeled by where it starts (0 = 0–25k miles). Reports without mileage are left out.
