Used OnStar To Diagnose Stabilitrac
I've been having intermittent "service stabilitrac" lights on my Envoy. They usually shut off on restart but the other day the light stayed on for quite a while. While I was driving I hit the OnStar button and had them run a live diagnosis and they found that an ABS sensor was causing the problem. Pretty cool that he could do that "on-line". I dropped it off at the dealer today. We'll see what THEY come up with!
