In our research we use the PPMY index to compare the reliability of vehicles. The PPMY index of a certain model is defined as the problems reported per thousand vehicles per Year. The total sales of the 2020 Lexus ES in the United States are 30,262 units [1]. If the total number of problems reported by Lexus ES owners in the last 6 years is 16, and the age of the vehicle is 6, the PPMY index can then be calculated as
PPMY Index = 16 / 30,262 / 6 * 1000 = 0.09.
