Happens to my SRT6 Roadster as well. In fact, I have it in the shop as I am posting for this very reason. Left town for a week and a half and came home to a dead battery. I thought it was a little soon (1 1/2 yrs and 28k) to have a battery issue, but I replaced it and then dropped it off at the dealer for another issue (heater core replacement). I advised them that my logic reasoned me to believe that there was something drawing down my battery and would they check it while doing the other work. Fast forward 1 month to Thanksgiving (out of town 4 days) and I had another dead battery (mind you this was a new battery 1 month old) and it is back at the dealer. I have a great dealer (yes I said it!) who has really taken care of my ride without any struggles, so I will wait and see.
