2012 Chevrolet Sonic LTZ: Third Time's a Charm
November 13, 2012
The heated seats in the Sonic LTZ are a simple on/off affair. There's no "low, medium, high" here, let alone a thumb wheel with like seven levels of adjustment. But that's ok, as their singular toasty temperature setting works for me. What doesn't work right is the switch. Normally you press once to turn 'em on and again to turn 'em off. But to shut the heater off, I discovered you have to press the button three times.
At first I thought I didn't press it hard enough (there's no tactile "click" action) and figured it was finicky and just took several attempts. Also, I don't remember it being faulty the last time I drove the car.
I checked into it further. with the key turned on but the engine off so I could maybe hear when it went off. Sure enough, I heard a faint "click" when I hit the button to turn the heater on (and the orange light kicked on to indicate so). When I deliberately pressed the button again to turn it off, the light went out but the heat stayed on. A second attempt yielded nada. A third and I heard the faint click as the heater shut off.
I repeated this for both seats to see if the action was consistent and it was -- it always took three presses to turn off both seat heaters. Wondering if this was a wide-spread glitch, I checked for a TSB but there wasn't one. We'll get it checked out next time we bring it in for service.
