My heated seats also stopped working shortly after I bought the $50k 2014 Crew Cab z71 ltz truck. After a second trip to the dealer I had them sit in it while I was still there so they could see that the back wasnt getting warm. They replaced the blower motors and heating elements in both seats. It worked for a short period and is now occassionaly working like it was before. Sometimes it works and sometimes it doesnt. Taking it back on Tuesday.
I also had a spark plug wire come off causing the eng light to come on. Repaired under warranty
