Mitsubishi Diamante owners have reported a total of 500 problems for their cars built in the 8 model years listed in the chart below. The chart shows the number of problems reported across all service years for each given model year of the Mitsubishi Diamante. The 2002 Mitsubishi Diamante cars have the most problems reported (156 problems).
| Model Year | Number of Problems |
|---|---|
| 2004 Diamante | |
| 2003 Diamante | |
| 2002 Diamante | |
| 2001 Diamante | |
| 2000 Diamante | |
| 1999 Diamante | |
| 1998 Diamante | |

The following chart shows the 25 most common problems for Mitsubishi Diamante cars. The number one most common problem is related to the vehicle's visibility (219 problems). The second most common problem is related to the vehicle's engine and engine cooling (85 problems).
It would not be fair to compare the Mitsubishi Diamante of an older model year to newer model years since older vehicles have been in service longer and thus are expected to have more problems. In order to compare the reliability across Diamante model years, we use the PPMY index which is defined as the problems reported per thousand vehicles per Year. A smaller PPMY index indicates greater reliability of the given model year cars.
PPMY = P / S / Y * 1000,
where P = total problems reported during the life of a Mitsubishi Diamante model year; S = total units sold of the model year; Y = years since the debut of the model year (the age of the vehicle).
The results are shown in Table 3.
Another way to measure the reliability across the model years of the Mitsubishi Diamante is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
