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 2021 Volkswagen Passat in the United States are 17,078 units [1]. If the total number of problems reported by Volkswagen Passat owners in the last 4 years is 28, and the age of the vehicle is 4, the PPMY index can then be calculated as
PPMY Index = 28 / 17,078 / 4 * 1000 = 0.41.
