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 2014 Lexus GX in the United States are 20,294 units [1]. If the total number of problems reported by Lexus GX owners in the last 11 years is 22, and the age of the vehicle is 11, the PPMY index can then be calculated as
PPMY Index = 22 / 20,294 / 11 * 1000 = 0.10.
