Suzuki Forenza owners have reported a total of 1,307 problems for their cars built in the 5 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 Forenza. The 2006 Suzuki Forenza cars have the most problems reported (419 problems).
The following chart shows the 24 most common problems for Suzuki Forenza cars. The number one most common problem is related to the vehicle's power train (317 problems). The second most common problem is related to the vehicle's electrical system (184 problems).
|Problem Category||Number of Problems|
|Engine And Engine Cooling|
|Vehicle Speed Control|
|Unknown Or Other|
|Other Fuel System|
|Electronic Stability Control|
|Gasoline Fuel System|
|Traction Control System|
It would not be fair to compare the Suzuki Forenza 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 Forenza 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 Forenza 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 Suzuki Forenza is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
