Buzzing sound

I have a sound coming from the right side of my dash which comes on after driving for about 10 minutes.  It has a vibvarting sound which gets louder as speed increases.  Dealer can not find cause..does anyone have this problem? I have a 09 blk coupe, LT2.

My '05 makes a huge noise when I plant the go pedal to the floor. Lots of tire smoke, too

brick

I had the intermittent buzz on my new 2012 convertible. Dealer replaced the right side air inlet screen. Told me there was a service bulletin for that problem.
