Porsche 986 reliability - let's get better info
#31
We have updated reliability stats for the Boxster that include owner experiences through September 30, 2011.
Repair frequencies, in terms of repair trips per 100 cars per year:
2004: 44, better than average, small sample size
2003: 53, better than average
2002: 135, about average
2001: 97, better than average
2000: 120, about average
1999: 71, better than average, small sample size
We have two additional statistics, "Nada-odds" and "Lemon-odds," to indicate the percentage of cars with no repairs in the past year and those that required 3+ trips to the repair shop.
For the years where we have enough data for these:
2001: 51, 11
Porsche Boxster Lemon-odds and Nada-odds
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.
Six IMS failures were reported for the 2010 calendar year, most of them for 2004-2005 model year cars (with the 2005 being a 987 rather than a 986).
No IMS failures have been reported for cars 2006 and newer.
No IMS failures have been reported for any model year since the beginning of 2011, with over 200 owners of 1999-2005 cars participating.
Rear main seal and air/oil separator repairs are far more common.
Thank you, once again, to this forum and everyone who has been helping. We'll have further updates in February and May. With more participants we could provide more precise information and cover all model years.

Hello Mkaresh,
If you are interested : 2001 Boxster S : Fuel pump at 62'000 miles.
I understood that the years (time) is mostly the problem, (..not the miles) for such failure.
PS: I did a preventive IMSB (LM Pro, dual row kit) at around 61'500 miles.
