No s**t... I have the same problem. The drivers seat in my 02 really looks bad, and I applied a lot of leather cleaner a moisturiser to it since the truck was new. I asked the dealer and they have allways been great to me, but they said that it was just normal wear and tear and not covered under warranty. It's only the seats bottom but it still looks bad, it could be do to the hot summers and very cold winters here (cleveland). Anyhow it sucks but there isn't much you can do.
