No have not noticed this but I have noticed moisture in the second row. We have clear carpet plastic that you normaly use in your house to protect the carpet. We have it in the second row and everytime after a down pour, I open the right rear door and see moisture under the plastic. This is after it has been sitting there in 100+ temps. I guess the water or moisture has been evaporating and getting stuck to the plastic. Maybe there is a leak some where
