I posted this some time ago at the PCA Boxster register after speaking with the attorney who represented the plaintiffs in the class action law suit against Porsche regarding failed IMS bearings. My understanding is that the Tiptronics have had far fewer failures than sticks but no one has ever been able to explain the reason for that. Hope this helps you.
"This morning I had a conversation with Steven Harris, the attorney at Knapp, Peterson and Clark Law Firm, that represented the plaintiffs in the class action law suit against Porsche regarding the IMS bearing failures. The following information is FYI and is specific to the percentage of failures that were repaired by Porsche under warranty or good will claims. I have received permission to post the information and if you have any more questions regarding any other aspect of the suit please call 818-547-5100.
The law suit involves the years 2001-2005 both base and "S" models that have the single row IMS bearing.
The failure rate, that has been reported from warranty and goodwill repairs, for those model years ranges from 4%-10% and involves 57,000 vehicles in the United Sates only. The actual percentages for each model year are available but Mr. Harris did not have them available and I did not press him for more of his time to dig them up.
The highest percentage of vehicles affected were in California and again he did not have the exact percentage available or a reason for that.
The failure rate for the early Boxsters 97-2000 model years is less than 1% (.02-.04%) however the scope of the suit spans a 10 year period and vehicles up to 130K miles and is not entirely exclusive to 2001-2005 models. I did not get into this any further so I encourage individuals possibly affected to call for more clarification.
Please understand this information is specific to percentages and nothing else and is not being posted to create another debate about the IMS issue, spleen venting about after market fixes, or displeasure about the results of the suit. I've been curious about the percentages of failures that have been theorized on Boxster sites and wanted to get some specifics regarding them. Since my vehicle is not involved, has had the LN bearing installed and falls in the very lowest percentage of failure my curiosity is satisfied."

Now to my real reason for joining in: I'm having the IMS quandary. Our Boxster has 30K miles, gets an oil change every 5K, and runs like a top. However; recently I have had a concern of the possibility of IMS failure. The more I read and research, the less I seem to be calmed. I've talked to the area LN engineering rep and he sez got to do it, while the Porsche Service Manager sez not to worry. Are there any stats/hard science relating to the probability of my single row IMS going south? What has been your experience?
