Interesting, thanks all. Yeah, I've seen the loose wires. I have had mine to the dealership already and they weren't able to repair it. They had my vehicle for SIX days and returned it to me with the same rattle. Lame.
I don't think mine is the wires though... when the vehicle is in gear, if you push up on the white ducting underneath, the rattle goes away. But not sure how to keep that happening... maybe a metal band across the bottom... but what would I anchor the two sides of the band into?
Ugh.
