Just driving down the road one day and the abs, traction control, and stablitrak turned off. lights came on, on the dash saying service abs and traction control. turned truck off and back on and the lights turned off and everything was fine, but within 30 minutes it comes back on. usually comes on when normal braking (not hard) you can feel the abs lock up and the lights come on saying traction control is off and abs is off. some days the lights come on as soon as you start the truck in the morning and some days it doesn't come on at all. never had the truck off road, on road use only, truck is stock and has not been lifted yet. i wash the truck every 2 weeks, and the truck only had about 38xxx miles on it when this happened and still is happening. the date reported was an estimate since i have been driving the truck with this problem for a couple months
