2012 Chevrolet Sonic LTZ: Seat Heater Confirmation

November 27, 2012

2012_Chevy_Sonic_1600_smell_update_2.jpg My family and I spent Thanksgiving weekend running around in our 2012 Chevrolet Sonic LTZ. Along the way I was able to confirm a couple of things about the seats.

As JDP pointed out recently, the seat heaters work great, but it takes three presses of the button to get the relay to trip and shut them off again. It's very like having a one-way bulb screwed into a three-way socket. The effect is consistent and repeatable, too, which makes me think that our alert readers are right about it having something to do with the programming (or lack thereof) of the control module in our Sonic's replacement seats.

Because of the special nature of our situation, I'm convinced that this isn't likely to be a widespread Sonic issue and it's certainly no hazard of the faulty circuit variety. It can wait until the next time we need service.

On the seat smell front, I am pleased to report these new buckets are not stinking up the place; I detected nothing, in fact. But at one point my wife -- who is a neutral observer that isn't aware of this car's seat saga -- did scrunch up her nose a bit and say that she smelled something funny.

This is a scenario I've encountered before, and I trotted out my standard response: it was the dog. 

Kobe, our Labrador puppy, is currently shedding something fierce, and he rode in the car a couple of times before my wife did. It's possible that she picked up a faint whiff of something else, but it's pretty safe to say the scent situation in here is much, much closer to normal than it has been in the past. Especially after I vacuumed out the dog hair.
