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 2009 Nissan Frontier in the United States are 23,018 units [1]. If the total number of problems reported by Nissan Frontier owners in the last 14 years is 43, and the age of the vehicle is 14, the PPMY index can then be calculated as
PPMY Index = 43 / 23,018 / 14 * 1000 = 0.13.
