Saturn Aura owners have reported a total of 1,831 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 Saturn Aura. The 2007 Saturn Aura cars have the most problems reported (861 problems).
The following chart shows the 22 most common problems for Saturn Aura cars. The number one most common problem is related to the vehicle's power train (338 problems). The second most common problem is related to the vehicle's steering (289 problems).
|Problem Category||Number of Problems|
|Engine And Engine Cooling|
|Electronic Stability Control|
|Vehicle Speed Control|
|Other Fuel System|
|Traction Control System|
|Gasoline Fuel System|
|Diesel Fuel System|
It would not be fair to compare the Saturn Aura 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 Aura 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 Saturn Aura 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 Saturn Aura is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
