I have a 2006 G6 GT. Somewhere between 1-2 years old, I swear my driver side seat heater kept turning on by itself. Took it to the dealership while under warranty and of coarse they couldn't duplicate the problem. They did say it wasn't getting as hot as it should. It has not turned on by itself since then, but then the passenger side started turning on by itself and my wife said it's not getting as hot as it used to. Do you think the dealership swapped some wires, so I wouldn't notice? I guess it worked because it didn't really bother me and my wife likes that it doesn't get so hot. But nobody likes it when it turns on in the middle of summer.
