My '13 Leaf SV w/premium has rear heated seats.
Actually, Nissan was included them in US Leafs from model year '12 to '15, then they started screwing with the configs starting w/model year '16.
Yes, my '19 Bolt Premier has rear heated seats.https://www.chevrolet.com/electric/bolt ... price/trim
seems to confirm it comes with the Premier trim on 2020. I went back to choose the '19 Bolt and confirmed that, as well. Gotta go to Premier. And, they mention it's for the outboard seats.
