📉 Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Acura TLX 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 TLX 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 Acura TLX 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 TLX Model Years

TLX Model Year	Problems	Sales [1]	Vehicle Age	PPMY Index
2022	38	12,130	4	0.78
2021	124	30,777	5	0.81
2020	89	28,894	6	0.51
2019	131	29,170	7	0.64
2018	143	32,113	8	0.56
2017	105	22,410	9	0.52
2016	154	33,880	10	0.45
2015	524	67,398	11	0.71

📊 Number of Problems Reported During the First Year
