From time to time, I will go to start my Pickup and the battery will be dead. I replaced battery, and it worked okay for a few weeks, then it happened again. I jump started vehicle, did ok for 3-4 weeks - then dead again. Dealer cant seem to find the problem. The problem started after the dealer replaced the radio after it experienced a blank screen on half of the screen. Dealer tells me that Chrysler won't authorize replacement of troubled radios with a new radio and they are only allowed to put "rebuilt" radios in vehicles with radio issues. I am not sure if the radio replacement is causing the battery drain but that is when it all started.
