We've updated our reliability stats for the 911 to include owner experiences through June 30, 2016. Reliability information elsewhere is based on a survey conducted in April 2015--well over a year ago.

Repair frequencies, in terms of repair trips per 100 cars per year (lower is better):

2004 911: 54, low, very small sample size
2003 911: 47, low, very small sample size
2002 911: 117, moderate
2001 911: 89, moderate, very small sample size

I'd very much like to get rid of the sample size notes and provide highly precise stats--merely need more owners involved.

Additional participants always helpful, especially for years without stats or with small sample sizes.
