I agree, a new battery could never hurt, and this is exactly what I will likely end up doing if this problem persists. My hesitation is that my Edge is show some of the same behaviors as others who posted in this topic indicating that replacing the battery didn't help. For instance, I have noticed on one occasion that the radio stayed on after I turned the car off and locked the doors, on another occasion the two screens in the dash stay lit after leaving and locking the car (waiting 2 minutes and they were still on, started the car again, turned it off, locked the door, and they went off), my seat, air, and radio all loose their last position every time I turn off the car, along with getting an odd message when I turn the car off (Please turn ignition off or start engine). Also, the battery is only drained after being left for a long period of time. If I stop for 20-30 minutes and get back in and start the car, it starts just fine. This tells me the battery is holding a charge. I am not dismissing the fact that it could be the battery, but everything that I'm seeing is pointing towards something else. Does that make sense?
