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 2003 Lexus RX in the United States are 34,746 units [1]. If the total number of problems reported by Lexus RX owners in the last 21 years is 4, and the age of the vehicle is 21, the PPMY index can then be calculated as
PPMY Index = 4 / 34,746 / 21 * 1000 = 0.01.
