Occasionally when I start the car, there begins a loud rattling in the middle dashboard, behind the radio/ a/c. It goes on and on until it decides to stop. I don't have an owners manual, and have no idea what this could be. Any help??
I too have an 06 Impala SS. it does the same thing. I've had it to the Chevy dealer and they can't find it or won't find it. They would have to remove the dash to get at it. Their answer "we don't hear anything" Shame on Chevy Dealers.... I too wish someone could answer the question with a soultion.
