12 volt battery dead

[rcmager]

In the three months I have had the FFE, it has been to the dealer three times, all for the same problem. When I start the car, I'll first get an inquiry on the left hand display asking if the car is plugged in. After I toggle no, it will start. Then I'll notice the charge ring outside will start flashing on and off when the car is parked. After a day of this, the car will not start. The screens are all dark and nothing will work. The car can't even shift out of park to be able to tow. The 12 volt battery is dead. A jump from the tow truck allowed the car to be started, moved to be able to be towed (I wasn't going to risk driving on the freeway not knowing if the car would keep going). The dealer is almost clueless. The first time, they didn't do anything because we were just worried about the flashing lights and it hadn't died yet. It died later that day. Then they replaced the battery. A month later, the car died again and the dealer has it. They have no idea as of now. Anybody else run into this problem?
