When my Avalanche was new I noticed the inside door panels were loose and ratteling. I went to the dealer where I bought the vehicle and checked the other Avs on the lot and they were all loose. I complaigned to the dealer. He checked his Avs and agreed. They took the vehicle in, removed all of the door panels, installed a foam strip at the top, and replaced the panels. Check your Avalanche and I am sure you will find the panels loose and rattling.
