just left the local dealer (different from where I bought it) for service #4 for vibration and he said its a known issue for "some" trucks and has another truck in the shop for the same issue but GM has no recommended fix for it so they will call me when they know how to fix it, otherwise they consider it "normal" to vibrate
UPDATE: lemon law claim has been submitted
