Volvo C70 owners have reported a total of 297 problems for their cars built in the 15 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 C70. The 2000 Volvo C70 cars have the most problems reported (47 problems).
The following chart shows the 23 most common problems for Volvo C70 cars. The number one most common problem is related to the vehicle's structure (47 problems). The second most common problem is related to the vehicle's electrical system (44 problems).
It would not be fair to compare the Volvo C70 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 C70 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 C70 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 C70 is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
