About two months ago I purchased a clean LX450. Been a lurker of the forums for at least a month before that. 
Anyway, haven't had any problems with the 450 up until now. Was heading down to Yosemite with my wife and my folks, and drove through about 3 hours of pretty solid non-stop rain. We stopped off in Redding to pick up a few items, and shortly after we got going again, we heard a sort of washboard squeal coming from under the hood.
It sounded almost like the divots that are on the side of the road that are used to wake you up if you start drifting, only higher in pitch.
At first I didn't think anything of it (thought I'd hit that), but shortly afterwards it did it twice more, each time longer. After the 3rd time it never came back (I should mention that after the 2nd time the rain stopped, so don't know if that's a factor).
The third time it happened, I played around a bit with it. Definatly got worse when I accelerated (louder/higher pitch), did not go away when I shifted into neutral and let the rig coast. No pulling or other funny business (just the sound).
After the third time we completed our trip to Yosemite (well, just outside) with no problem, including climbing Old Priest grade (nice and steep). The sound never came back.
Anyone have any ideas of things to check?
