fourfourto .... THAT'S IT! Mine is more of a groan sound when INSIDE, more like your #1 sound clip. Your others are like my outside sound .. groany, springy. What in the world is this about?! I'm hoping f5fstop listens to your sounds soon. I wonder if this is what his groan had sounded like, too. (I was at the dealer today .. my battery died at the gas station.
They gave me a new one.)
