NHTSA Complaint #11065703 — 2014 GMC SIERRA 1500

DURING DRIVING, THE STABILITY SENSORS WOULD GO OFF AND SHOW UP STATING STABILITY TURNED OFF, OR POWER STEERING TURNED OFF. THE VOLTAGE ON VEHICLE WOULD SUDDENLY DROP FROM 15 TO 9 AND THEN BACK UP. THIS WILL USUALLY TURN OFF THE INTERIOR LIGHTS AND ELECTRONICS. I HAVE DISCUSSED THIS WITH OTHER 2014 SIERRA AND SILVERADO OWNERS AND THEY ALL ADVISED THIS WAS OCCURING ON THEIR VEHICLES. THERE IS A GROUND WIRE THAT WAS NOT PROPERLY INSTALLED UNDER THE DASH WHICH CAUSES HIGH RESISTANCE MATERIAL TO CAUSE ELECTRICAL ISSUES. DURING ONE OF MY DRIVES TO WORK GOING 60 MPH, THE ELECTRICAL COMPONENTS SHUT OFF AND CAUSED THE ENGINE TO STOP RUNNING. I WAS ABLE TO PULL OVER WHILE COASTING ON NO POWER AND RESTART THE VEHICLE AND IT WOULD CONTINUE TO GO. THERE HAVE BEEN TIMES WHERE THE STEERING WHEEL WOULD JERK WHILE STATIONARY AS WELL. AFTER MANY FORUM DISCUSSION THIS ALL RELATED BACK TO THE GROUND WIRE NOT BEING PROPERLY INSTALLED BY THE MANUFACTURER.
