We have updated reliability stats for the Boxster and Cayman that include owner experiences through June 30, 2010.

Other sources of car reliability information won't cover the more recent months until the summer or even fall of next year.

In terms of repair trips per 100 cars per year:

2008: 36, better than average

2006: 47, better than average

2005: 49, better than average

2004: 67, about average, small sample size

2003: 94, about average, small sample size

2002: 118, about average

2001: 115, about average

2000: 92, better than average

1999: 117, about average

Important note: these cars are only driven an average of 5,500 miles a year, about half as much as the average car. No adjustment has been made for this.

Very consistent results from year to year. The result for the 2000 might be a bit lower than it should be, judging from the results for other model years.

I'd like to report specifically on the IMS failure rate, but we will need more participants to do this. So far, with 171 986s participating for an average of about six months, only four IMS failures have been reported, two of them over a year ago.

Thank you, once again, to everyone who has been helping. We'll have further updates, possibly including additional model years depending on the number of participants, in November and February.

We'll be previewing the next update to members around the middle of the month. 426 Boxster and Cayman owners now signed up. A great start, but more remain needed to fully cover all model years.

Starting this month we have a new question to measure, as objectively as possible, the severity of a problem. Many people have been asking for reliability stats that weight problems by how severe they are, and once we have enough responses with the revised survey we'll start providing this.

Also, updated reliability stats this month.

As always, the more owners participate, the better the information we can provide to everyone.

We have updated reliability stats for the Boxster and Cayman that include owner experiences through September 30, 2010. Other sources of car reliability information won't cover the months since April until the summer or even fall of next year.

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

2008: 59, about average

2007: 61, about average, small sample size

2006: 53, better than average

2005: 45, better than average

2004: 71, about average, small sample size

2003: 55, better than average

2002: 92, about average

2001: 98, better than average

2000: 69, better than average

1999: 156, worse than average, small sample size

Important note: these cars are only driven an average of 5,500 miles a year, about half as much as the average car. No adjustment has been made for this.

I'd like to report specifically on the IMS failure rate, but we will need more participants to do this. A few more failures have been reported recently, but still about two to three per 100 cars in the past year.

Thank you, once again, to everyone who has been helping. We'll have further updates, possibly including additional model years depending on the number of participants, in February and May.
