I have a Model Y. When not using my iPhone but using the FOB, with Walk Away and Lock engaged, with Notifications ON for unlocked windows and doors, with AutoFold Mirrors ON and with Horn notification ON, when I walk away I do not hear the horn, see the mirrors fold, and I also do not receive a Notification that the car has not been locked. Upon return to the car I merely open the door handle and do not have to use the FOB along with window pillar. Any ideas why the car is not locking?
