Hi, I have a 2011 Ford Edge Ltd, the battery keeps dying. I noticed this drain issue last year when I exhausted my AAA service in a month. The trunk door opens by itself. The radio does not work. The abs module was changed this week and the battery continues to drain. The driver side door lock was replaced 2 years ago and other parts have been changed and the battery continues to drain. I can't connect the phone. Mechanic can't figure it out. Please help.
