I have a 2011 traverse that has had many issues! The latest being that the traction control off/service stabilitrack light comes on, after I start driving. When I start it, the message is not there and no check engine light. When I start driving is when the lights come on as well as the ABS light. It has a new abs sensor, as the old one was busted off by the mechanic that was fixing my timing chains. He also broke one of my front axles which Has also been replaced. Any idea what could be causing those lights? This thing has been a headache since day one!
