Toyota Highlander owners have reported a total of 6,673 problems for their cars built in the 26 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 Highlander. The 2019 Toyota Highlander cars have the most problems reported (573 problems).
The following chart shows the 35 most common problems for Toyota Highlander cars. The number one most common problem is related to the vehicle's power train (826 problems). The second most common problem is related to the vehicle's service brakes, hydraulic (723 problems).
It would not be fair to compare the Toyota Highlander 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 Highlander 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 Highlander 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.
