📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Lincoln Aviator 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 Aviator 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 Lincoln Aviator 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 Aviator Model Years

Aviator Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2022	94	18,237	4	1.29
2021	56	15,855	5	0.71
2020	169	27,289	6	1.03
2005	63	18,884	21	0.16
2004	113	27,042	22	0.19
2003	166	27,076	23	0.27

📊 Number of Problems Reported During the First Year
