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 2009 Nissan Gt-r in the United States are 2,518 units [1]. If the total number of problems reported by Nissan Gt-r owners in the last 9 years is 20, and the age of the vehicle is 9, the PPMY index can then be calculated as

PPMY Index = 20 / 2,518 / 9 * 1000 = 0.88.
