Kia Motor Optima owners have reported a total of 10,243 problems for their cars built in the 20 model years listed in the chart below. The chart shows the number of problems reported across all service years for each given model year of the Kia Motor Optima. The 2013 Kia Motor Optima cars have the most problems reported (1,873 problems).
The following chart shows the 34 most common problems for Kia Motor Optima cars. The number one most common problem is related to the vehicle's engine and engine cooling (3,328 problems). The second most common problem is related to the vehicle's equipment (940 problems).
It would not be fair to compare the Kia Motor Optima of an older model year to newer model years since older vehicles have been in service longer and thus are expected to have more problems. In order to compare the reliability across Optima model years, we use the PPMY index which is defined as the problems reported per thousand vehicles per Year. A smaller PPMY index indicates greater reliability of the given model year cars.
PPMY = P / S / Y * 1000,
where P = total problems reported during the life of a Kia Motor Optima model year; S = total units sold of the model year; Y = years since the debut of the model year (the age of the vehicle).
The results are shown in Table 3.
