📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Mitsubishi Montero 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 Montero 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 Mitsubishi Montero 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 Montero Model Years

Montero Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2006	6	2,663	18	0.13
2005	1	3,832	19	0.01
2004	7	3,875	20	0.09
2003	52	13,781	21	0.18
2002	133	26,995	22	0.22
2001	210	41,817	23	0.22
2000	67	3,899	24	0.72
