REAR VIEW CAMERA STARTING WORKING INTERMITTENTLY. TOOK VEHICLE TO DEALER TO REPAIR. DEALER UPDATED SOFTWARE AND THE PROBLEM PERSISTED THE SAME DAY. RANDOM SCREEN FOR JUST THE BACKUP CAMERA WILL BE EITHER BLACKED OUT OR BLUE STATING TO SERVICE REAR CAMERA SYSTEM. HAVE TAKEN MY VEHICLE BACK TO THE SAME DEALER THREE SEPARATE OCCASIONS TO RESOLVE THIS ISSUE TO NO AVAIL. NOW THAT MY WARRANTY IS EXPIRED THEY HAVE A FIX THAT WILL COST ME OUT OF POCKET. THEY ARE OFFERING COST ASSISTANCE BUT THE PROBLEM WAS NEVER RESOLVED IN THE FIRST PLACE.

HESITATION WHEN ENGINE IS COLD SHIFTING FROM REVERSE TO DRIVE. SOME SHIFT IS SO HARD THAT IT FEELS LIKE BEING HIT FROM BEHIND. TOOK TRUCK TO DEALERSHIP TO CORRECT THE PROBLEM. THEY PERFORMED THE TSB 18-NA-355. THIS DID NOT CORRECT THE PROBLEM. DEALERSHIP ADVISED THERE WAS NOTHING ELSE THEY COULD DO ABOUT THIS ISSUE.

ELECTRICAL SYSTEM, ENGINE, EXTERIOR LIGHTING
AS I WAS DRIVING HOME MY CHECK ENGINE LIGHT CAME ON AND ALL OF MY LIGHTS WENT OUT. I HAD NO TAIL LIGHTS AND THE RADIO STARTED SAYING NO SIGNAL DETECTED. THE DASH SCREEN WAS SAYING SERVICE KEYLESS ENTRY SYSTEM. AND I HAD NO RUNNING LIGHTS BUT MY HEADLIGHTS. PRETTY SCARY THINKING NO ONE COULD SEE ME AS THEY WERE DRIVING BEHIND ME AT A HIGH RATE OF SPEED. MY TRUCK ONLY HAS 200 MILES ON IT SO THIS IS REALLY SCARY TO BE HAVING ISSUES SO EARLY IN THE OWNERSHIP OF THIS TRUCK. I'VE ALWAYS HAD FORDS BUT THIS TRUCK CAUGHT MY EYE AND I STEPPED OUT OF MY COMFORT ZONE AND NOW WISHING I WOULD HAVE STAYED IN IN.

SERVICE BRAKES
MY BRAKES ARE SQUEAKING VERY LOUDLY THEY HAVE BEEN SINCE AUGUST. I WAS DRIVING DOWN THE ROAD ON US1 AND PREPARED TO STOP TO MAKE A TURN AND MY TRUCK WOULD NOT STOP. I WAS MAKING A RIGHT TURN AND ENDED UP IN THE OTHER LANE OF ONCOMING TRAFFIC SIDEWAYS BECAUSE I TRIED TO TURN MY TRUCK TO SLOW IT DOWN. I COMPLAINED ABOUT MY BRAKES SEVERAL TIMES TO THE DEALERSHIP THEY ORDERED ME NEW BRAKES WITHOUT EVEN LOOKING AT MY VEHICLE AROUND AUGUST 8TH. WE ARE NOW AT THE LAST TWO DAYS OF SEPTEMBER AND THEY STILL DO NOT KNOW WHEN THE BRAKES WILL COME IN. THIS IS A SERIOUS SAFETY ISSUE AT THIS POINT. I HAVE NO OTHER VEHICLE TO DRIVE. I BOUGHT A 70,000 TRUCK AND MY AND MY FAMILY'S SAFETY IS ON THE LINE. GMC NEEDS TO FIND ME A COMPARABLE LOANER VEHICLE UNTIL MY TRUCK IS REPAIRED.

SERVICE BRAKES, ELECTRICAL SYSTEM, POWER TRAIN
THE FIRST THING THAT HAPPENED WAS THAT ALL OF THE ELECTRICAL SYSTEMS ON MY TRUCK WENT OUT AND MY TRUCK WOULD NOT START. IT FINALLY STARTED BUT IT WOULD NOT MOVE FINALLY IT WOULD MOVE BUT VERY SLOWLY THIS HAPPENED ON 11/20/2019 I HAVE DOCUMENTATION THROUGH ONSTAR FOR THIS INCIDENT. MY BRAKES STARTED SLIPPING ON 07/01/2020 AND STILL DO NOT WORK PROPERLY. MY TRANSMISSION HAS NEVER SHIFTED CORRECTLY. WHEN I ACCELERATE OR WHEN I SLOW DOWN THERE IS A SHUDDER AND A JERKING SOUND. AFTER SITTING FOR A WHILE WHEN MY TRUCK IS PUT IN REVERSE IT HESITATES AND THEN SEEMS TO JUMP INTO GEAR.
