I'm a professional mechanic
I'm a professional mechanic and I figured out this problem with my girlfriend's 2016 civic hatch. The keyfob is extra sensitive when it comes to getting wet and accidental pressing of buttons. My fix is I took out the batteries of her main fob and gave her the extra fob for everyday use which does not have the window feature. I still have the main fob as our backup but we no longer have to worry about this problem. Fyi there's a tiny screw holding the fob halves together.
