📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Kia Motor Sedona 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 Sedona 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 Sedona 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.
