So I am currently sitting at an EA station in SoCal and i had a weird thing happen. I am sitting in the car with it fully powered down and driver door open. All of a sudden the AC turns on full blast with nothing else turning on. I pushed start to turn on accessory mode and it turned down to my settings from before (auto low). I turned the car back off and within 5 sec it turned on full blast. I am currently sitting with accessory mode on while charging. Anyone else have this happen?

Also how should i report this to Ford?

Ill update also if it does it after im done charging.

Im on a trip back from Phoenix right now and this is my 7th fast charge on the trip and never had this happen. Also outside temp is 78 so lowest temp over last few days.

The A/C compressor is used to cool the batteries if necessary. Interesting that it turned on the blower in the car though. Maybe the system is trying to precondition the cabin while plugged in?
