I had these same two issues earlier this year during a snow storm. The camera was covered up with snow, told me to clean the camera / sensor - I ignored it and then it tripped the pre collision and hill assist errors. As soon as I turned my car off (without cleaning anything off!) things went back to normal.

I imagine it is just flawed logic in the Ford Pilot360 software. Something I wish to turn off.

But it has not happened since.
