CaptJack,

Thanks for confirming yours has never done this. Mine has always done it and I have 13k miles on it now. Seems to only happen if it has been sitting, mostly over night.

Reason I have never bothered to take it in is because I figure they simply would say its normal and that they never heard of the problem and that it wouldnt happen for them.

It did it again this morning.... I do need to take the chance and bring it in though.

Maybe I need to record the sound!
