Volvo S70 owners have reported a total of 768 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 Volvo S70. The 1998 Volvo S70 cars have the most problems reported (312 problems).
The following chart shows the 24 most common problems for Volvo S70 cars. The number one most common problem is related to the vehicle's vehicle speed control (144 problems). The second most common problem is related to the vehicle's electrical system (121 problems).
|Problem Category||Number of Problems|
|Vehicle Speed Control|
|Engine And Engine Cooling|
|Gasoline Fuel System|
|Unknown Or Other|
|Other Fuel System|
|Electronic Stability Control|
It would not be fair to compare the Volvo S70 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 S70 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 Volvo S70 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 Volvo S70 is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
