Mazda Millenia owners have reported a total of 203 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 Mazda Millenia. The 2001 Mazda Millenia cars have the most problems reported (37 problems).
| Model Year | Number of Problems |
|---|---|
| 2003 Millenia | |
| 2002 Millenia | |
| 2001 Millenia | |
| 2000 Millenia | |
| 1999 Millenia | |
| 1998 Millenia | |
| 1997 Millenia | |
| 1996 Millenia |
The following chart shows the 22 most common problems for Mazda Millenia cars. The number one most common problem is related to the vehicle's engine and engine cooling (38 problems). The second most common problem is related to the vehicle's power train (32 problems).
It would not be fair to compare the Mazda Millenia 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 Millenia 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 Mazda Millenia 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 Mazda Millenia is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
| Model Year | Problems Reported |

| 2002 Millenia | |
| 2001 Millenia | |
| 2000 Millenia | |
| 1999 Millenia | |
| 1998 Millenia | |
