NHTSA Complaint #11019959 — 2014 GMC SIERRA 1500

FIRST INSTANCE: (THIS ISSUE HAPPENED THREE TIMES IN ONE DAY BEFORE BEING ABLE TO BE REPAIRED) WITHOUT WARNING THE VEHICLE LOST ALL POWER AND THE MOTOR DIED WHILE TRAVELING AT APPROX. 35MPH FOR SEVERAL SECONDS. WHEN IT POWERED BACK UP EVERYTHING WAS RESET AS IF THE BATTERY HAD BEEN DISCONNECTED. THE DEALERSHIP FOUND A "LOOSE GROUND WIRE" UNDERNEATH THE DASHBOARD AND ATTRIBUTED THE OCCURRENCE TO THIS. SECOND OCCURRENCE: (LESS THAN A MONTH LATER AND HAPPENED TWICE WITHIN A FEW MINUTES) WHILE TRAVELLING ON THE EXPRESSWAY AT APPROX. 70MPH AND AGAIN WITHOUT WARNING THE VEHICLE LOST ALL POWER AND THE MOTOR DIED FOR SEVERAL SECONDS. WHEN IT POWERED BACK UP EVERYTHING WAS RESET AS IF THE BATTERY HAD BEEN DISCONNECTED. THIS HAPPENED AGAIN WHILE EXITING THE HIGHWAY JUST MOMENTS LATER AT A MORE MODERATE SPEED, AGAIN WITH ZERO WARNING. DEALERSHIP NOW STATES THE PROBLEM IS WITH THE POSITIVE BATTERY TERMINAL WIRE & HARNESS.
