Picked up my truck from the dealer, they fixed the creaky dash by replacing the hud bezel I thought it was the radio bezel making noise but I was wrong no more creak... as for the doors they are talking with gm for a fix no solution as of yet..
I have the same problem truck is going in after the new year.the salesman has the same basic truck and his is also doing it and going in to service before mine so we will see
