NHTSA Complaint #11153652 — 2018 GMC TERRAIN

DRIVING ON A DOWNSLOPE HEADING NORTH ON 65 GOING INTO TENNESSEE FROM ALABAMA I EXPERIENCED A LOSS OF POWER SYSTEM LIGHTS WENT OFF ALONG WITH GAUGES GOING OFF AND ON. AT WHICH TIME STABIATRAK AND TRANSMISSION LIGHTS CAME ON SAYING TO PULL OVER IMMEDIATELY.WE DID SO CALLED GM ONSTAR WHERE THEY TOLD US WE WOULD EXPERIENCE A LOSS IN POWER BUT COULD TRAVEL ONWARD. WE CHOSE TO GET TOWED, HOWEVER DUE TO THE HOLIDAY WE HAD DIFFICULTIES GETTING A TOW AND WERE FORCED TO DRIVE HOME 90 MILES AWAY. THE PROBLEM DID NOT PRESENT ITSELF AGAIN ON THE DRIVE HOME. WE TOOK IT TO A GMC DEALER IN VESTAVIA HILLS THEY PULLED OFF THE CODES BUT HAD NO REASON FOR THE ISSUE NOR WERE THEY ABLE TO GET SERVICE BULLETINS FROM GM ON THE ISSUE. I DOCUMENTED THE FINDINGS WENT HOME AND A LATER ON 11/23/18 THE PROBLEM OCCURRED AT ABOUT 130 MILES FROM THE FIRST INCIDENT. THIS TIME IT HAPPENED GOING UP A HILL AND GIVING THE CAR GAS DID NOTHING TO GET ME UP THE VERY SMALL GRADE. I HAD TO PUT IT IN REVERSE AND GET A RUNNING START AT THE HILL IN ORDER TO MAKE IT HOME. I CALLED GM AGAIN AND REQUESTED A TOW TO A SECOND DEALER IN TRUSSVILLE, AL THEY WERE UNABLE TO EVEN SEE IT UNTIL MONDAY 11/26/18. I AM VERY FEARFUL THAT IF WE HAVE TO DRIVE IT AGAIN THAT I MAY NOT BE AS LUCKY.
