📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Toyota Scion Xb 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 Scion Xb 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 Toyota Scion Xb 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 Scion Xb Model Years

Scion Xb Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2012	1	32,566	11	0.00
2011	4	19,909	12	0.02
2010	20	20,719	13	0.07

2005	100	67,396	18	0.08
2004	40	25,098	19	0.08
