Hey guys, small issue with my 07 Denali recently, for the past couple months my Service Stabilitrak light comes on when i start my car, but then goes away when i shut it off. It will stay off for a few days sometimes but sometimes it stays off for a week or 2. Anyone else have an issue with it before? I would take it to the shop, but the light has never stayed on after i shut it off. Also, if im stopped at a stoplight, everynow and then it feels like someone tapped me from behind, like it lunges forward few inches. But i never lifted my foot off the brakes, the light is not active when it does this. Could they be tied together? Any help wou;d be help to me, thanks.
