I remember the other problem water down into the b pillar cameras making them inoperable because they freeze up.
That's going in next week.
Better get it fixed under warranty. This happened to my model S. It's a pretty penny to fix. Maybe not be a big deal for all you warm weathered folks, but the first 30 minutes of my drive until the cameras heat off all the Frozen moisture inside FSD doesn't work. So forget about a thousand mile drive anywhere at around @REM.
