Toyota Scion Xd owners have reported a total of 91 problems for their cars built in the 4 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 Scion Xd. The 2008 Toyota Scion Xd cars have the most problems reported (67 problems).
The following chart shows the 20 most common problems for Toyota Scion Xd cars. The number one most common problem is related to the vehicle's service brakes, hydraulic (26 problems). The second most common problem is related to the vehicle's vehicle speed control (13 problems).
|Problem Category||Number of Problems|

It would not be fair to compare the Toyota Scion Xd 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 Scion Xd 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 Scion Xd 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.
