A few months ago I noticed my 11' G has this werid tapping sound next to driver panel area (the corner where the left speaker layout) very annoying.
the thing is that symthom disappears with changing temperature throughout day, e.g in the evening the sound is gone but early morning appears again.

today brought my car in the dealer, they installed insulator to the panel, seems working now, so FYI for those who suffers similar problems.

 

thanx for the input

 

Thanks. Mine does it too and I thought it was the windshield. I'll definitely have it looked at next time I take it in.
