It's done this a few times about once a month. After sitting for just a few hours I'll go to drive and the first time I use the brakes (lightly,barely at all) the pedal vibrates bad and ABS engages. Then right after the AdvanceTrack light will go and the display will say to check AdvanceTrac. It goes right away when I hit the button to turn AdvanceTrac off. Next time I drive it....normal. Any thoughts?

i had teh same problem, it went away after sometime, i mentioned it to my dealer but i don't think they did much of anything
