Many have been asking to understand how many of the 997 cars have had IMS (intermediate shaft) failures. Although the people on this board are not necessarilly a random sampling of 997 owners I would like to see a poll to get a better sense of it.
  • Please vote only once for each 997 you own (yes or no).. you can post multiple times but only vote once
  • Please include details of your car and engine if it failed via IMS (m96 or M97) and when.
  • Please let us know if there were any mitigating factors (low oil, overheat, etc) , car sat for months, high revs, low revs, that might've led to the failure
  • Please post only about IMS failures, this is not about RMS failures
  • Please post only for your car, no heresay or posting for a friend who doesn't frequent the board
  • Please post what was done to rectify the failure if your car failed (CPO engine, engine out of pocket, used engine, sold, insurance fire, pushed it into a river etc

Hopefully this will help owners and soon-to-be owners get a sense of how frequently this occurs.

Default issue

IMS and RMS fixed under warranty/CPO at about 30K miles, later one less then 6 months later and 5K miles one failed again and out of warranty by a few months, dealer fixed issue again but had to get special approval.

Not to give this issue any less weight but it's common to find these issue really blowing up on message boards.

I also own a ducati which has a plastic tank (most modern bikes have plastic tanks) and the design of this is like a saddle over the motorycle frame. It turns out that for whatever reason (plastic changing over time, alcohol fuel) that many of the tanks are spreading and coming off the mounts on the frame. Here's a poll that shows that it's happening on 60% of ducatis:

there was a class action lawsuit for this which was "won" by the lawyers. Owners of these bikes get a mounting kit if they ask for it (shown to only be a temporary fix). The Lawyers get 850k. And the owners who submitted their bikes for inspection as a part of the suit get 2k apiece. There were very few of those.

You also find similar issues with BMWs on their message boards.

My point is that we probably shouldn't be holding our breath that a class action lawsuit will garner real results. I really believe that manufacturers should design products that work for a reasonable amount of time even when subjected to reasonable abuse. I don't think Porsche is fulfilling that commitment here. I also don't think that it's as bad an offense as you see in other cases. It's terrible if it happens to your car but in terms of percentage it's not as bad as other vehicles. That doesn't absolve porsche but I think that it makes it less likely that anything will come of a lawsuit etc.
