Would you happen to know the part number or where I could get info on the additional shock sensor? I’ve got a 2018 limited with the factory perimeter / all sensor alarm set up and wondering if I can add this.Funny, this happened to me recently as well. Twice in one night. Never before and never after. But mine was showing shock sensor notification (I have installed the Ford factory shock sensor). So the next morning I lowered the sensitivity a little and so far so good. Did you get notifications on your my ford app? that will tell you if it was shock sensor or something else, maybe somehow you accidentally got a shock sensor!
