Has anybody else seen where you'll turn on the seat warmer, then after a minute or so the bottom part turns itself off while the back stays on? If I click on the bottom part, it immediately turns itself off again until the next time I drive the car. I've tried a logo reset so far with no change in behavior. I'm near the end of my warranty period so I'll probably need to bring it in to get fixed along with any other small things that I want covered.
