Vibration noise at dash/windshield
I have an 08 coupe and if I go over 60mph, i get a vibration/ buzzing sound coming from where the dash and windshield meet. Thought it may have been the wiper arm but sound still occurs if the wiper is moving. Driving me nuts as I tend to drive faster than 60 
. I took the cabin filter out from the engine compartment since it must be the wind coming thru but nothing seemed out of place.

It runs along the bottom for the window on the outside under the wipers. commonly it vibrates at the passenger corner near the curve. It is a composite piece with a seam. To check put some tape over it and go for a drive. SOME WILL SILICON UNDER IT TO THE GLASS OTHERS JUST TAPE.
Replacement part runs around $100 and is a DIY job if your handy.

GM has not addressed the problem with a design change.
