Just got this warning light and a corresponding notification in FordPass. Has anyone else experienced this?

I was hoping to go a full two weeks without needing service on a critical safety feature. Will post updates as this situation develops/is resolved.

That's a new one. I assume you'll be taking it into the dealer?

So the light went back off after leaving the car for a few minutes. Not exactly inspiring confidence though.

The restraints control module fuse looks good. Wouldn't really suspect a fuse if the issue is intermittent, but that's about as far as I'm willing to pry before my service appointment.

Got the car checked out today, and the tech couldn't find any problems with the passenger airbag or restraints control module. I haven't seen anything come up since Saturday, so it seems like this was just a blip. The leading theory is that there was some latency with communication between modules that fixed itself shortly afterward.

I also got a software update for PAAK, which seems to have helped with my Android's connectivity, but I've noticed some unexpected behavior with intelligent cruise control since getting the car back. If that persists, I'll start a new thread.

Following this thread. When I got my onslaught of errors, the restraint indicator lamp came on too, but much like your situation the technicians couldn't find anything wrong. Mine showed up along with a zillion other safety/assist malfunction warnings, but it doesn't seem like it was a true mechanical failure. Got the 12V TSB applied just in case, so we'll see.
