My truck shut down on the way home from delivery. Some Bozo at the dealer did not tighten the negative cable after doing the computer updates that were required by GM. Needless to say, they are no longer my servicing dealer.
Upon reading your post again, have the dealer do a load test on the battery, if it shows a weak cell have them replace it. If the battery was shorted out on their lot, it's up to them to replace it.
