It may be that your battery is dead and won't hold a charge. A new battery may fix the problem, but your Armada is so new, I would imagine it's still under warranty, which would cover this problem with the battery.

Best things to do is to get it diagnosed and fixed. If there's a draw on the system, you'll need a good technician to figure it out--with luck, under warranty!

If your alternator is not charging, your battery will eventually die, Have a repair shop put a meter on the alternator to see if its charging.
