This 12 volt power issue has happened to me twice now with my 2013 Ford Fusion Energi during the three years I have owned the car. The second time convinced me that it was not a fluke. So I found the TSB 15-0028 mentioned here about the frayed wiring and replacing the TCU. I called my Ford Service and they want the car all day to replicate the problem before they would take any action. I told them it would probably be a long wait since it's only occurred twice in three years. I asked the rep jokingly, should I wait till it happens again and have the car towed in? She said yes. If this is a known problem why can't I get the TCU replaced? And who can I contact higher up the Ford food chain to get the TCU replaced?
