AS far as carwash - Did you have FOB in your pocket while walking around spraying? If so mine does that, except it's not the hazards it's the door unlock perimeter lights triggering. I have also noticed that if I'm in garage by the truck with FOB on me you get the occasional truck wake up, fuel pump priming sound. I think it's related to the Ford Pass app communicating with the on-board modem (as I have my cell phone on me as well) IDK, this is one of the items on my truck that I have to research WHY does it do this?
On the drive home, I was coming to a stop at a light, and the truck lurched very noticeably as I was almost at a stop. At the exact moment I was thinking to myself, "that's never happened before....WTF is that?!" I caught a glimpse of an alert on the dash that said "Brake (something something) Interrupted." Has never happened before or since.
