Mitsubishi Montero Sport owners have reported a total of 449 problems for their cars built in the 9 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 Montero Sport. The 2000 Mitsubishi Montero Sport cars have the most problems reported (127 problems).
The following chart shows the 22 most common problems for Mitsubishi Montero Sport cars. The number one most common problem is related to the vehicle's engine and engine cooling (69 problems). The second most common problem is related to the vehicle's service brakes, hydraulic (61 problems).
It would not be fair to compare the Mitsubishi Montero Sport 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 Montero Sport 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 Montero Sport 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 Montero Sport is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
