Porsche Boxster reliability -- let's get better info

Maybe it could be used in a class action lawsuit( that is if my engine ever implodes)

To be honest, I'd rather avoid this application, if only because it provides an incentive to distort the results.

244 Boxster and Cayman owners now signed up. Four model years are now in the survey, and another four are close to the minimum sample size. A good start, but more are needed to provide precise results for all model years.

I signed up. Went to "Car Reliability Comparisons" and found no entry for Porsche in the drop down menu. What's up?

[ridetheworld]

I had the same issue, couldn't find Porsche anywhere. I guess I am tarded.

What's up is that we can't post any results in that area until we have enough people who've been participating for 3+ months. There's an inherent delay built into the survey process. To avoid possible sources of bias, it only collects data going forward.

With 273 owners signed up so far, we should start having results for some model years in November. The 1999, 2000, 2001, 2002, and 2005 are already in the survey, and the 2003, 2006, 2007, and 2008 are all close.

I saw the results yesterday for the 2001 Boxster...I knew the cars had maintenance issues but jeez. According to the number of times in the shop the Boxster is one of the worst. Good thing is I also own one of the most reliable, a 2005 4runner. I am going to try and get the IMS updated after the cold season.

Updated stats in about two weeks. 417 owners now signed up. Very good, but more remain needed to fully cover all years.

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.

Repair frequencies, 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 180 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 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.

My 1998my boxie has not had one issue since I bought the car over 6 months ago...it is my dd and I have had nothing but fun!!!I have replaced tires and coolant cap(which I still add a small bit of coolant every 3 weeks) but other than that...no probs...oh..my mileage is 92,xxx and is a strong tip!!!

Oh wait...I do have one issue...The lever for the trunks does not unlock anymore...but that's okay...I use the small screwdriver method,lol

From this page it's possible to select a different model year or specify a problem area.
