Suzuki Aerio owners have reported a total of 145 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 Aerio. The 2003 Suzuki Aerio cars have the most problems reported (42 problems).
| Model Year | Number of Problems |
|---|---|
| 2007 Aerio | |
| 2006 Aerio | |
| 2005 Aerio | |
| 2004 Aerio | |
| 2003 Aerio | |
| 2002 Aerio |
The following chart shows the 21 most common problems for Suzuki Aerio cars. The number one most common problem is related to the vehicle's power train (19 problems). The second most common problem is related to the vehicle's suspension (19 problems).
It would not be fair to compare the Suzuki Aerio 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 Aerio 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 Aerio 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.
