Haven't had the problem in any vehicles, but my wife put one of them on top of one of our old CRT Televisions in the kids rec room. The thing either leaked or the oil spilled somehow, and it basically started dissolving the plastic top of the TV. I went to go move the thing and had literally sunken into the plastic surface by a few millimeters. I pryed it out of the top of the TV, and there's now a divot in the top in the shape of the air freshener.
My wife now puts those oil air freshener things on a glass dish before we put them in the rooms.
