Yea, there is a thread on this issue. a handful of guys had this problem. Knock on wood I have not yet. I have kept my goat in the garage since new and have tinted windows. It seems owners in the hot climates have complained of this problem alot more. Good Luck... Should be under warranty. Check it out.
