Understanding the 2020 Kia Optima complaints
Which systems appear most often?
The largest component group is engine: 100 entries, or 50.0% of classified component entries. Next is powertrain: 25 entries, or 12.5% of classified component entries. A complaint can name several components, so these percentages describe the entries in the file, not the percentage of vehicles affected. Only the leading component groups are displayed.
At what mileage were problems reported?
The median reported mileage is 59,005 miles, based on 26 complaints with usable mileage (19.0% of the 137 complaint incidents). Half of those reported mileages are at or below the median and half at or above it. This sample excludes missing or unusable mileage and does not predict when another vehicle will develop a problem.
Use these patterns to prepare questions about a particular vehicle's service history. Complaint reports describe submitted experiences; they do not establish the cause, repair cost, or condition of every 2020 Kia Optima.
