Audi A7 owners have reported a total of 188 problems for their cars built in the 12 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 Audi A7. The 2019 Audi A7 cars have the most problems reported (68 problems).
The following chart shows the 21 most common problems for Audi A7 cars. The number one most common problem is related to the vehicle's electrical system (38 problems). The second most common problem is related to the vehicle's engine and engine cooling (25 problems).
It would not be fair to compare the Audi A7 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 A7 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 Audi A7 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.
