Toyota 4Runner owners have reported a total of 6,952 problems for their cars built in the 31 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 Toyota 4Runner. The 2004 Toyota 4Runner cars have the most problems reported (896 problems).
The following chart shows the 30 most common problems for Toyota 4Runner cars. The number one most common problem is related to the vehicle's structure (1,636 problems). The second most common problem is related to the vehicle's suspension (896 problems).
It would not be fair to compare the Toyota 4Runner 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 4Runner 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 Toyota 4Runner 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.
