I had the issue fixed with a new applique, I think this was the service center's term, was replaced once already. But the problem still happens because it turns out (as they mentioned to me at the time) the double-stick rubber material is actually porous. I am still supposedly on the list for a fix once Tesla comes out with a kit with a new membrane material that is not porous. I have no idea when that might be but I was told Tesla is aware of the problem.
I was also told that the moisture is not actually getting inside anything and it is merely cosmetic. Sorry this is info I got at the SC and I have not personally dug into the lenses myself - it is a small niggle and down here it dries out quickly.
