PPMY Index and Problem Occurrence Trend

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 2001 GMC Yukon in the United States are 70,848 units [1]. If the total number of problems reported by GMC Yukon owners in the last 17 years is 509, and the age of the vehicle is 17, the PPMY index can then be calculated as

PPMY Index = 509 / 70,848 / 17 * 1000 = 0.42.
