My heated seats never turn on automatically. The setting is ON in the infotainment screen. They only turn on automatically when I preheat the car. Shouldn't they turn on when I start driving and its 20 degrees outside? My 2017 Volt does and they automatically turn down as I drive-- to a lower setting. Very Nice.. why isn't my Bolt doing the same? Is mine messed up? Does anybody's Bolt turn on seat heat automatically when driving?
