I may have had the same noise. I looked under the hood and found some friction tape around a wiring harness starting to unravel. I pulled the excess off, and and some of the noise went down. I think i may have had some more tape somewhere else that i couldn't see. The noise did finialy go away. I do still have the rear driver side squeek.
My other bummer is a rock hit the windshield on the passenger side, 1/4" from the edge. in the first 5 min, the crack grew 6". It's now halfway across the window. Not looking foward to the replacement cost.
