I went and got an alignment,a day after the stabilitrak and traction control message came on. I went back to see if it could be fix it and was told it didn't come on when they test drove it. The same day it came on again, so I went to a GMC dealership. I was told my steering wheel pos sensor is bad. I was in motion on a city street,going and coming from work(happens in same exact spot on the street(s). This is my only form of transportation and what I need to do.
