NHTSA Complaint #11415730 — 2014 GMC SIERRA 1500

ON SEVERAL OCCASIONS SPANNING MULTIPLE YEARS THE TRUCK LOSES POWER WHILE BRAKING AND TURNING AT SLOW SPEEDS. ON MORE RARE OCCASIONS, BUT STILL NUMEROUS, THE SAME PROBLEM OCCURS WHEN BRAKING AT HIGHER SPEEDS WITHOUT TURNING. THE TRUCK DASH LIGHTS, MEDIA SCREEN AND HEADLIGHTS ALL DIM OR FLICKER AS A TICKING OR POPPING NOISE IS HEARD BEHIND THE DASH MUCH LIKE AN ARCHING ELECTRICAL WIRE. MOST OF THE TIME WHEN THESE SCENARIOS HAPPEN THE DISPLAY ON THE DRIVERS DISPLAY SCREEN READS STABILTRAK WARNING. ALSO WHEN THE PROBLEM OCCURS WHILE TURNING AND BRAKING AT LOW SPEEDS THE TRUCK WILL COMPLETELY LOSE POWER AND POWER STEERING AS WELL AS ASSISTED BRAKING. ONCE THE TRUCK COMES TO A STOP THE IGNITION, AND ALL ELECTRICAL SYSTEMS ARE COMPLETELY UNRESPONSIVE LIKE THE BATTERY IS DEAD. IN ORDER TO START THE TRUCK AGAIN, I HAVE TO GET OUT OF THE TRUCK, OPEN THE ENGINE HOOD AND OSCILLATE BOTH THE NEGATIVE AND POSITIVE BATTERY CABLES. MOST OF THE TIME THE TRUCK WILL START UP AFTER DOING THIS. SOMETIMES I HAVE TO USE BOOSTER CABLES TO GET IT TO START. NEITHER THE CABLES OR THE TERMINAL CONNECTORS ARE LOOSE AS THEY HAVE BEEN INSPECTED BY A DEALER SERVICE TECH AND A LOCAL MECHANIC.
