📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Kia Motor Optima Hybrid 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 Hybrid 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 Hybrid 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.

Table 3. Use PPMY Index to Compare Reliability Across Optima Hybrid Model Years

Optima Hybrid Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2018	2	1,570	8	0.16
2017	28	6,741	9	0.46
2016	3	5,399	10	0.06
2015	17	10,894	11	0.14
2014	49	9,743	12	0.42
2013	75	16,027	13	0.36
2012	136	12,757	14	0.76
2011	46	3,886	15	0.79
