NHTSA Complaint #11221668 — 2018 GMC SIERRA 1500

NO TRANSMISSION POWER REGARDLESS OF THE GEAR SHIFTER POSITION. I TURNED THE ENGINE ON AND OFF SEVERAL TIMES TRYING TO GET A SOLUTION, NO LUCK. I RETURNED TO THE VEHICLE 5 MINUTES LATER AND DID GET IT TO MOVE,,,WOULD ONLY GO 25 MPH AT 3000 RPMS. I WAS IN THE MIDDLE OF WI NOT NEAR ANY MAJOR DEALERSHIP ON-STAR WAS USELESS SAYING I HAD A MAJOR ENGINE PROBLEM AND THE COMPUTER WAS TRYING TO PROTECT THE ENGINE. I WAS DIRECTED ME TO A CHRYSLER DEALER SHIP, WHO TOLD THEY COULD NOT GET ME IN FOR 2 WEEKS, SUGGESTED ANOTHER BRANCH WHICH WAS OVER 45 MILES AWAY. I DROVE 5 MILES TO A FRIENDS HOUSE AND WAS ABLE TO FIND A DEALERSHIP IN JANESVILLE, WI (FAGAN). WHEN I STARTED THE VEHICLE TO DRIVE TO JANESVILLE, THE TRANSMISSION DID WORK. FAGAN SPENT 2 HOURS WORKING ON IT, AND COULD NOT FIND A CAUSE FOR THE PROBLEMS, THEY CHECKED EVERY COMPUTER, COULD NOT DUPLICATE WHAT HAPPENED. THEY REPROGRAMMED ALL THE COMPUTERS. THEN IN CINCINNATI, OH THE POWER STEERING ASSIST WENT "OFF", WHILE STAIONARY. I TRIED RESTARTING SEVERAL TIMES TO NO AVAIL, DROVE THE 3 MILES LEFT TO THE G'KIDS HOUSE, NO POWER STEERING, TRAILER PROBLEM LIGHJT ON, NO RPM OR MPH NEEDLES MOVING. CALLED LOCAL DEALERSHIP (BORCHARDING) AND THEY SUGGESTED I DRIVE IT TO THEIR LOCATION 12 MILES AWAY. WHEN I STARTED IT, THE POWER STEERING WAS BACK ON, BUT THE UNIT WOULD NOT GET OUT OF 2ND GEAR, RAN 40 MPH AT 2500 RPM, WARNING LIGHTS ALL ON, ENGINE LIGHT STILL ON. NEXT MORING I STARTED THE VEHICLE, EVERYTHING WAS OKAY INCLUDING THE TRANSMISSION PROBLEM, BUT STILL HAD THE "CHECK ENGINE ON", THE DEALERSHIP KEPT IT (2) DAYS, INVOLVED GMC ENGINEERS, COULD NOT DETERMINE THE CAUSE FOR ALL THE PROBLEMS,INCLUDING LOSS OF "STEERING ASSIST". THEY DROVE IT OVER 50 MILES ON TWO TRIPS,COULD NOT DUPLICATE WHAT HAPPENED. THEY TOLD ME IT WAS SOME KIND OF COMPUTER PROBLEM, BUT COULD NOT DETERMINE, THEY RESET EVERYTHING AGAIN.
