At my SC visit mid Dec, the SC removed a one way air valve plug that is part of the pillar camera assembly. While it did not fix the issue completely, say after an overnight parked AM rain, what it seems to have done is allow more airflow exchange near the camera glass during driving. The net result is much less condensation obscuring the camera. And a drive with fast moving air clears the lens / camera area enough the reduce the issue.
Just completed an 1,100 mile trip, over rainy / snowy Mt Shasta, and it worked.
They did the fix within an hour. I bet with the right part of the service manual, do it yourselfers could do this at home w/out the SC visit. Curious if anyone has additional comments.
