2011 Z71 Tahoe and have been having trouble with the service stabilitrack/traction control light coming on. Initially the code said it was the wheel hub assembly...changed that out and everything was fine...for about 6 months, then the light came back on. Still said wheel hub assembly, so I changed them once again (assembly still under warranty). Everything fine for about 2 months. Light is now back on and gives C0710 (steering position sensor) code which there was a TSB put out about how to clean the connector, apply some dielectrical grease and wedge the connector. Did what the TSB recommended but the service stabilitrack/traction control lights STILL come on....Any suggestions? This is my wifes daily driver and now I am concerned about her safety.
