Same thing happened to me a week ago. I have 2500 miles on my H3. OnStar said there were issues with the ABS, but it was not serious. In talking to the service rep - he confirmed it was not serious.
The service rep did give me a work-around to see if it was a "glitch". I pulled over, put the H3 in neutral and and manually turned of the traction control.
Then manually turned it back on. This I was told would reset the "computer". Which it did. The DIC went back to being happy and I have not seen the problem since.
I will have it checked in the near future when more convenient.
Hope that helps.
