NHTSA Complaint #11084792 — 2015 GMC CANYON

ON SEVERAL OCCASIONS I HAVE LOST ALL POWER STEERING AFTER GETTING 2 SERVICE WARNINGS. IN THIS TYPE OF VEHICLE WITH ELECTRIC POWER ASSIST STEERING, IT IS INCREASING DIFFICULT TO STEER. (WORSE THAN AN OLD TRUCK WITHOUT POWER STEERING) IN THE EVENT OF AN EMERGENCY, IF THIS WERE TO HAPPEN SUDDENLY, I CAN NOT SEE HOW IT WOULD BE POSSIBLE TO MAINTAIN CONTROL OF THE VEHICLE. I AM GETTING 2 WARNINGS. THE FIRST IS TO "SERVICE STABILITRACK" AT THE SAME TIME, "SERVICE POWER STEERING DRIVE WITH CARE". AT THIS POINT I LOSE ALL POWER STEERING. THE ERRORS OCCUR WHEN DRIVING, AND HAVE ALWAYS HAPPENED AT HIGHWAY AND INTERSTATE SPEEDS (40+ MPH?). IN ALL INITIAL INSTANCES, THE TRUCK WAS TRAVELING ON WELL MAINTAINED ROADS, WHICH WERE STRAIGHT. I WAS NOT MAKING ANY TURNS SUCH AS A TRAFFIC SIGNAL OR INTERSECTION. ON OCCASIONS I HAVE BEEN ABLE TO PULL OVER, STOP, TURN THE TRUCK OFF, RESTART AND THE ERROR CLEARS. IN THE LAST 2 DAYS I HAVE CLEARED THE ERROR, BUT IT RETURNS WITH THE SAME RESULT, NO POWER STEERING. AFTER READING SOME REVIEWS ONLINE, IT SEEMS TO BE A SOMEWHAT COMMON ISSUE, AND MOST RESULT IN A LOSS OF POWER STEERING. MY TRUCK IS CURRENTLY AT THE DEALER AND THE PART WAS NOT IMMEDIATELY AVAILABLE (POSSIBLY SHOWING THE NUMBER OF ISSUES??) THE DEALERSHIP HAS STATED THAT IT IS THE 'STEERING GEAR', OR RACK & PINION WHICH HAS FAILED. THE VEHICLE HAS ADDITIONALLY HAD A RECALL FOR SIMILAR ISSUES, BUT THE DEALERSHIP STATED THAT IT WAS FOR A 'SOFTWARE UPDATE'. THIS IS SAID TO HAVE BEEN THE FIX IN OTHER SIMILAR SITUATIONS. I SEE THIS AS A SERIOUS SAFETY ISSUE, THE MOST SERIOUS I HAVE HAD IN ANY TRUCK I HAVE OWNED. THIS IS THE REASON FOR FILING THIS REPORT.
