I have a slight tear on the passenger rear seat and i have no idea how that happened?! It's a tiny tear near one of the perforated holes under the head rest. If i can think of something, it's from putting a computer and the cardboard box edge might be sharp enough to scratch it open, but it's very common to put boxes on the back seat, so i am not too sure. Anyone else having tearing issues on the Model X seats? Thanks.
