I just found out today that a noise I heard at an autocross this past Sunday was due to intermediate shaft failure. It has 67,700 miles or so on it and I've owned it for six and a half weeks, or under 2000 miles. It's a '99. I've been a Porsche nut for nearly 20 years, finally got one, and am now regretting ever buying one. I should have grown a brain and bought the Honda instead.
I've been quoted $11k for a new factory 2.5 installed or $15k for a new factory 3.4 installed.
I don't have the dealer work on the car, so Porsche is not aware of the failure, and I'm sure they wouldn't care to know and wouldn't do anything about it if they did know. I'm just sorry to be an idiot German car lover. I may never own another Porsche.
