Audi Q7 owners have reported a total of 309 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 Q7. The 2007 Audi Q7 cars have the most problems reported (89 problems).
The following chart shows the 24 most common problems for Audi Q7 cars. The number one most common problem is related to the vehicle's fuel system, other (50 problems). The second most common problem is related to the vehicle's electrical system (44 problems).
|Problem Category||Number of Problems|
|Other Fuel System|
|Engine And Engine Cooling|
|Vehicle Speed Control|
|Electronic Stability Control|
|Diesel Fuel System|
|Unknown Or Other|
|Gasoline Fuel System|
It would not be fair to compare the Audi Q7 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 Q7 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 Q7 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 Audi Q7 is to use the total number of problems reported during the vehicle's first year in service, as shown in the Table 4.
