Got my first "Stop Safely Now" warning today, and I wasn't even driving. My car is parked in the garage, this evening I went out to drive down to the market. Unplugged the car, got in, pushed the button, noticed a couple of extra clicks (relays?), and although everything turned on, the green "Ready to Drive" symbol didn't come on. Then, about two seconds later, I got the "Stop Safely Now" warning with the chimes. Shut everything off, tried it again, same thing. Let the car sit for an hour or so, tried it again, same thing. Battery shows 100% charged.
Just out of curiosity I checked the Ford mobile app, and I have a red warning for Battery system health.
So, guess it's off to the dealer in the morning.
