I use to have an 06 civic that I bought with dealer added leather heated seats by Katskin. When the heated seats stopped working, the dealer wouldn't honor the warranty for the heating element which was different from the one for the leather. It had to be serviced by a 3rd party. Plus by that time the warranty ran out and wasn't worth the cost of fixing. 900 dollars for 3yrs of use and the leather didn't hold up like I'd liked it to.
It's probably still worth looking into if your educate yourself on warranties and or handy.
