Mine is similarly haunted. It has opened by itself when I’m in the house and the fob is on the table. Sometimes it won’t open or close with the fob, dash switch or under hatch foot swipe. I will just do it manually and in a couple of days, plus or minus, it functions normally again.
It is often accompanied by the drivers window not working expressly as it should. It goes to fully closed then opens again to about 25%. With a little finesse I can close it manually to keep out the elements. No luck with service so far.
