Just had mine replaced under the extended warranty. I don't have the paperwork in front of me, but I remember it had "leather seat cover" as one of the items. Also, I don't recall anything about a heating element being list there. So, I'm assuming it's already built into the seat cover.

I also had the passenger mirror motor replaced and I believe the parts alone came out to around $1300.
