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 2000 Infiniti QX4 in the United States are 10,800 units [1]. If the total number of problems reported by Infiniti QX4 owners in the last 23 years is 39, and the age of the vehicle is 23, the PPMY index can then be calculated as
PPMY Index = 39 / 10,800 / 23 * 1000 = 0.16.
