Service stabilitrac keeps coming on and sometimes when it comes on it flashes and every time it flashes it applies the right front brake pulling the truck to the right. When you go to slow down to pull over the anti lock brakes turn on until you are almost completely stopped and once the stabilitrac light comes on steady and stops flashing it will not do it any more until you turn the truck off and reset it. It mainly does it on the highway at higher speeds but it has done it in town also. No pattern to when it does it sometimes I may drive 100 miles before it does it and sometimes it comes on as soon as I cut the truck on and take off. It has come on when stopped and foot on brake getting ready to leave. Have had it to the dealer to be fixed but so far they have not been able to figure out exactly what is the problem

All stabilitrak/traction control shut off. Dealer states code C0455, steering angle sensor. Please investigate how many code C0455 have been listed for years. Service bulletins have been issued by GM. Known issue not being repaired causing stabilitrak and traction control to disengage. The numbers posted in forums indicate a large problem. Should be a recall.
