We have our first reliability stat for the Audi A8 based on owner experiences through March 31, 2011.

With a reported repair rate of 145 repair trips per 100 cars per year, the 2004 A8 is worse than average. The sample size was very small, so this result is not precise.

We'll have further updates in August and November. With more participants, we could provide more precise information and cover all model years.

We have updated our car reliability stats for the Audi A8 based on owner experiences through June 30, 2011.

Repair frequencies, in terms of repair trips per 100 cars per year:

2006: 35, better than average

2004: 120, about average but not far from "worse than average"

Very small sample sizes in both cases, so these stats are not precise.

We'll have further updates in November and February. With more participants, we could provide more precise information and cover all model years.

We have updated our car reliability stats for the Audi A8 based on owner experiences through September 30, 2011.

Repair frequencies, in terms of repair trips per 100 cars per year:

2006: 103, about average

2005: 129, worse than average (on the borderline)

2004: 121, about average

We have updated our car reliability stats for the Audi A8 based on owner experiences through September 30, 2012.

Repair frequencies, in terms of repair trips per 100 cars per year:

2006: 104, worse than average on stricter recalibrated scale

2005: 157, worse than average (on the borderline)

2004: 86, about average

Very small sample sizes in all cases, which might explain much of the variation from year to year.
