Suzuki Vitara - Problems, Statistics, and Analysis

Suzuki Vitara owners have reported a total of 147 problems for their cars built in the
6 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 Suzuki Vitara.
The 1999 Suzuki Vitara cars have the most problems reported (63 problems).

Table 1. Total number of problems by model year for Suzuki Vitara

The following chart shows the 18 most common problems for Suzuki Vitara cars.
The number one most common problem is related to the vehicle's engine and engine cooling
(27 problems).
The second most common problem is related to the vehicle's suspension (27 problems).

Compare Reliability Across Model Years Using PPMY Index

It would not be fair to compare the Suzuki Vitara 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 Vitara 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 Suzuki Vitara 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.
