Kia Motor Sephia owners have reported a total of 2,806 problems for their cars built in the 8 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 Sephia. The 1998 Kia Motor Sephia cars have the most problems reported (937 problems).
| Model Year | Number of Problems |
|---|---|
| 2003 Sephia | |
| 2002 Sephia | |
| 2001 Sephia | |
| 2000 Sephia | |
| 1999 Sephia | |
| 1998 Sephia | |

The following chart shows the 22 most common problems for Kia Motor Sephia cars. The number one most common problem is related to the vehicle's service brakes, hydraulic (678 problems). The second most common problem is related to the vehicle's engine and engine cooling (366 problems).
It would not be fair to compare the Kia Motor Sephia 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 Sephia 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 Sephia 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.
Another way to measure the reliability across the model years of the Kia Motor Sephia is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
