This is apparently a problem that is happening across many Ford models. There's a thread on the Energi forum that has links to other forum threads for this along with a 4/4 TSB for Fusion & MKZ, but that didn't solve the OP's problems. A common mention is this seems to happen after the car is parked in the sun so we might get more reports going into summer. Good luck, and report back as how they resolve this. http://www.fordfusionenergiforum.com/topic/802-fob-problems/
