We just had this problem yesterday on our 2015 Ford Fusion SE Hybrid. Came out to the car and all the windows were rolled down....who knows for how long? Problem is that it rained a ton during this time and now the inside of the car is wet. Next battle is to prevent a mildew odor. We didn't know if some signal went to the car (not from the fobber), to activate the windows. Glad someone already posted this subject because we were thinking it was a ghost or something! LOL
