I got something similar.
I got the message twice know that the camera for the PCS (Pre-Collision
System) was not working because of a fogged windshield.
The windshield seems clear to me so I expect there was some blocking (fogged) between
the camera and the windshield. After a couple of minutes, the message disappears and I think
everything was alright ( little difficult to test the pre-collision system).
I not noticed of the Road Sign Assist wasn't working because I was not looked for it.
The problem looks like some fogged headlight who disssapear after a view minutes.
