Anytime I start the car with a dusting of snow or ice on the back window within a mile or so the lines from the rear defroster melt the snow (even though the defroster was not on). It even does this with the entire climate control system in the off mode. Is t his happening to anyone’s else car?

Behavior was the same on my 2011 SE. No heated seats or mirrors. The defroster would come on when cold all by itself, I never needed to push the button. I suspect it just does it auto after startup for a pre determined time, maybe only when below a certain temperature. . Would be nice if it turned on the light to let you know when it is on/off.

same with my 2011. The rear glass defrost works when the button is not depressed, however, heated seats and front defrost are turned on. I don't know if those automatically turn on the rear or not. It is rare that the heated seat and front defrost are not running every day from November to April.
