Thats seems to be the way it is concerning getting something fixed at the dealer under warranty. You have to bug the piss out of them, make threats, and scream and yell if you want it done right. You get so annoyed you get to the point where you just say F-it and never fix it. I think they know that and thats their plan. I bet when the warranty runs out you can anything you want fixed right away and done right the first time in a reasonable time frame for the cost of a small fortune and your first borns soul. Not just Hummer, my Audi dealer is the same way.
