well i have never had any starting issues or whatnot, it seems to have all of its power, altho i did notice that sitting at lights idling the motor will have just an almost unnoticable rough spot every 20 seconds or so. basically they said one of my cylinders is leaking, so it needs a new head, and to go ahead and drive it and they will give me a rental car when i bring it in for service.

Now as to opening a case, what do you mean by that? i called hummer yesterday and was talking to the guy and said "so i gotta get a new head and im worried this will happen in the future, where do we go from here" and he said i got the 4yr 50k warranty and if it happens again they will put a parts note on that part i guess and extend the warranty on that part. how do i get the extra coverage you guys are talking about? pm me if its best kept off the forum.
