We too had "drained battery" problems. We purchased a 2011 Dodge Journey Lux on May 27,2011. June 2, 2011 leaving work battery was dead. On advice of the salesman we jump started the car. It started immediately on connecting the cables, drove straight to the dealership. Next day they called and said "can't duplicate problem" you must have left the lights on. June 16, 2011 leaving work dead battery. They kept it two days put over 80 miles on it and again, can't duplicte problem. If it happens again don't jump start it bring to us dead so we can read "error codes". July 18, 2011 again dead battery. Had the car loaded on a truck and delivered to them dead. They kept it 12-days. Following week after never hearing from anyone I called they told me they found a bulletin stating the passive entry feature was the problem. Moisture was getting in the button on door handles and causing the system to keep the vehicle communication bus awake, therefore, draining the battery. They replaced both front driver and passenger door handles. August 2, 2011 when I picked up my car the service manager said Chrysler was designing a new handle and I might want to turn the passive entry off. Everything okay until November 19, 2011 dead battery. At this point I knew it was of no avail to call the dealership, we just jump started the car. I did call Monday to report it, their lack of concern was comforting, and did not ask if I wanted it brought in. On January 14, 2012 dead battery. I called dealership and talked with the saleman that sold us the car. He agreed we must have a "lemon" he would talk to management and call me Monday. Their offer was to trade in my "used" car with 3680 miles on it, sell me a car in value of what I owed, not what I paid including my trade in. I considered filing lemon law even though I did not want to. I decided to take it to a different dealership. I dropped it off on Sunday, they called me Monday come pick up your car. Seems there was bulletin that came out August 10, 2011 recommending they "flash reprogram the Body Control Module with new software". Everyone at this dealership were wonderful, a pleasant change from where I bought it. After being told this I searched the internet and found they actually issued a previous bulletin on June 14, 2011 for "drained battery" recommending the same reprogram. After reading the posts here there were several different "solutions" from dealerships for drained battery. We have not had a problem since the module was reprogrammed and I also turned the passive entry back on. Hope this helps those of you having same problem. Mind you, I live in Florida and everytime I had to wait for a tow truck for 30, 45 minutes or longer it was 100 degree weather, I was melting and NOT happy. The service manager and other personnel at the dealership where I bought my car were very abrupt, rude or just plain insolent. I will never buy from them again. That's what they call 5 star service for you!
