I've never had a problem with mine. My Aveo stays in the garage most of the time and isn't driven very far usually. When I know it's gonna be outside for a while, I always check it once every week and check it before I put it in the garage for days at a time. I've had that car for 16 months now, and I don't believe that little light came on once. Plus, whenever I filled up my tires, I used a gauge, which when I read it, every tire was off by about 2-3 psi. Everytime. You just gotta check your tires at least once a week.
