Thanks for having this come back to the top of the stack. Mine has started doing this on hot afternoons when I start the car to drive home from work. Squeals for about 5 seconds or so shortly after cranking her up. The PDF should be really helpful with the dealer, so thanks much for that. It's funny how things like this can alter one's plans; I have thought I might want to deal with this before taking a long trip to the hot Southwest.
