Subaru Legacy owners have reported a total of 3,401 problems for their cars built in the 30 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 Subaru Legacy. The 2005 Subaru Legacy cars have the most problems reported (244 problems).
The following chart shows the 31 most common problems for Subaru Legacy cars. The number one most common problem is related to the vehicle's engine and engine cooling (406 problems). The second most common problem is related to the vehicle's electrical system (383 problems).
It would not be fair to compare the Subaru Legacy 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 Legacy 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 Subaru Legacy 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.
