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.

VISIBILITY/WIPER
BACK UP CAMERA IS AWFUL AT NIGHT. THIS IS A SAFETY ISSUE BECAUSE YOU CANNOT SEE ANYTHING WHEN BACKING UP. MY TRUCK HAS 323 MILES ON IT AND I WENT TO DEALERSHIP THEY SAID I WOULD HAVE TO LIVE WITH IT. THAT IS NOT ACCEPTABLE TO HAVE A SAFETY FEATURE THAT IS FAULTY.

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, STEERING
EVERYTHING WAS FINE FOR ABOUT 6 MONTHS AFTER HAVING PURCHASED VEHICLE AS NEW. THEN I GOT WARNING LIGHTS ASKING ME TO BOTH SERVICE THE PARKING BREAK AND SERVICE ESC WITH A WARNING THAT DRIVING WOULD BE COMPROMISED JUST OVER 60MPH. I NOTIFIED DEALER WHO SAYS THEY FIXED THE GLITCH BUT IT HAPPENED AGAIN. THE LAST TIME, MOST RECENTLY, I TRIED TO START THE TRUCK THE NEXT DAY AND ALL THE WARNING LIGHTS CAME ON. THIS WAS FOLLOWED BY A COMPLETE SHUT DOWN. NO ENGINE, NO LIGHTS - NOT EVEN LOCK/UNLOCK WITH KEY FOB. IT HAD TO BE TOWED. THIS IS A 2020 VEHICLE AND SEEMS LIKE IT WILL STRAND ME SOME PLACE AT THE VERY LEAST. AWFUL, EXPENSIVE, AND PERHAPS DEADLY DYNAMICS HERE. GMC, GET YOUR ACT TOGETHER. YOU OWE US IMMEDIATELY. PROVIDE THE FIX IMMEDIATELY OR GIVE ME MONEY BACK WITH NO CONTEST.
