Same thing had happened to me about 2 weeks after I got mine. I had braked right in a water puddle at a stop sign and the Stab Sys/Traction Fail message came up. Probably just a coincidence with the timing of the message. However, when I called OnStar to do a diagnostic check, they didn't show any problem. I took it to the dealer the next day and they had to replace a sensor. As the posts above said, it is not dangerous. Also, as mentioned above, the worst that would happen is that your anti-locks would not function ... you would have regular braking. Enjoy your H3 .. it's like nothing else!
