Probably has something to do with auto climate control. Unless you are remote starting your truck every time. Mine is typically only on in the truck if i remote start it and it deems its cold enough to need it. You can also look at climate settings for reentering the truck. I dont know if it maintains last settings or not for heated seatDoes anyone know of a way to have the heated seats not come back on when I turn off and turn back on my truck?
