2020 GMC SIERRA 2500 Complaints

THE SCREEN ON MY TRUCK HAS GONE BLANK SEVERAL TIMES AND THE VOLUME ON THE RADIO GOES SUPER LOAD AND THE ONLY WAY TO STOP IT SEEMS TO BE TO STOP AND TURN OFF THE TRUCK, OPEN THE DOORS AND RE START TRUCK. TODAY, I COULDN'T GET MY SCREEN TO GO OFF IN MY TRUCK WHEN I TURNED IT OFF, I TRIED TURNING OFF, RESTARTING ETC BUT TO NO AVAIL. I'M AT WORK NOW AND FEAR THAT THE BATTERY WILL GO DEAD BEFORE I GET OFF WORK. I JUST HAD THE TRUCK AT GMC 2/6/2021 AND WAS TOLD THAT THEIR WERE NO RECALLS. ALSO, NOTE THAT WHEN THE SCREEN KEPT GOING OUT I TOOK IT TO THE DEALER AND THEY SAID THEY HAD TO REFLASH/REPROGRAM IT WHICH TOOK 5 HOURS.

BRAKES SINCE NEW SQUEELED. TOOK TO DEALER AND DEALER SAID IT WAS NORMAL. HAVE HAD THE TRUCK ABOUT 11 MONTHS NOW. DEALER STATED GM NOW USES A DIFFERENT PAD MATERIAL AND I WOULD HAVE TO PAY FOR IT AT A COST OF CLOSE TO $1,000 TO REPLACE THE PADS.

THE VEHICLE PULLS TO THE RIGHT OR LEFT INTO ONCOMING TRAFFIC WITHIN 800 FEET OR SOONER DEPENDING ON SPEED. THIS OCCURS ON CITY STREETS OR INTERSTATE. GM AND GM APPROVED DEALERSHIPS SAY THIS IS DONE TO GM SPECIFICATIONS. THE FIRST 7000 MILES, IT DIDN'T PULL. AFTER GM SHOP ALIGNED, AND 3 MONTHS LATER, IT IS UNSAFE TO OPERATE.

WENT OUT TO MY VEHICLE THAT HAS BEEN SITTING IN MY DRIVEWAY FOR 24 HOURS AND ATTEMPTED TO UNLOCK IT WITH THE KEY FOB. NOTHING. TRIED THE OTHER FOB. NOTHING. USED THE KEY TO UNLOCK THE DOOR AND GET IN TO PUSH BUTTON START AND NOTHING. I PLUGGED BOTH BATTERIES INTO CHARGERS AND THEY WOULD START TO CHARGE, THEN DISCHARGE AFTER THE BATTERIES GOT UP TO ABOUT 20% I CALLED GMC ROADSIDE ASSISTANCE AND THEY SENT SOMEONE OUT. THE SERVICE GUY SHOWED UP ABOUT 45 MIN LATER AND HOOKED UP A JUMP BOX TO EACH BATTERY. STILL NO LUCK IN GETTING IT STARTED. HE SAID IT MUST HAVE SOME MAJOR ELECTRICAL ISSUES. SINCE WE COULD NOT GET IT TO SHIFT TO NEUTRAL, HE COULD NOT TOW IT AND I AM NOW WAITING FOR A TOW IN THE MORNING. THIS TRUCK HAS LESS THAN 10,000 MILES ON IT. I'M DEALING WITH THIS LESS THAN 5 MONTHS INTO OWNERSHIP AND THIS COMES AFTER I HAD TO TAKE IT INTO SERVICE THE SECOND DAY OF OWNING THE VEHICLE BECAUSE I HAD A DEF SENSOR CRYSTALLIZE AND GO BAD. SO, I OWNED THE TRUCK FOR LESS THAN 24 HRS AND HAD TO PUT IT IN THE SHOP FOR A WEEK. NOW, IT GOES BACK. THIS IS RIDICULOUS FOR A $81,000 TRUCK THAT HAS LESS THAN 10K MILES.

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.

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.

TL* THE CONTACT OWNS A 2020 GMC SIERRA 2500. THE CONTACT STATED THAT WHILE DRIVING AND TOWING A TRAILER, SHE DISCOVERED THAT THE BRAKES WERE OVERHEATING. THERE WAS A STRONG BURNING HOT ODOR COMING FROM THE BRAKES. THE CONTACT PULLED OVER AND DISCOVERED ALL FOUR BRAKE ROTORS WERE EXTREMELY HOT. THE CONTACT DROVE AND DROPPED OFF THE TRAILER. THE CONTACT DROVE 20 MPH AND DOWN SHIFTED TO CONTROL THE SPEED TO GET BACK HOME. THE DEALER DAVE ARBOGAST BUICK-GMC (3540 S CO ROAD 25A, TROY, OH 45373, (937) 335-0068) STATED THAT INCORRECT BRAKE PADS WERE INSTALLED ON THE VEHICLE FROM THE FACTORY AND THERE WAS A TECHNICAL SERVICE BULLETIN FOR THE FAILURE. THE VEHICLE WAS NOT REPAIRED DUE TO THE REPLACEMENT PARTS NOT BEING AVAILABLE. THE MANUFACTURER WAS CONTACTED AND PROMISED TO PROVIDE A CALLBACK. THE FAILURE MILEAGE WAS 500.

2020 GMC SIERRA DENALI DURAMAX 3000 MILES TRIED TURNING ON TRUCK THIS MORNING TO GO TO WORK AND WOULD NOT EVEN CRANK IT IS A PUSH START OPTION HAVE NO CLUE ON HOW IM GOING TO TAKE IT TO THE DEALERSHIP IF I CANT GET IT OF PARK INTO NEUTRAL FOR A TOW TRUCK AT LEAST ! TRUCK DOES NOT CRANK IT THROWS ME A TON OF MESSAGES STABILITY TRAK DSC ABS POWER REDUCED 4WD CHECK TRAILER LIGHTS. BUNCH OF MESSAGES I TOOK VIDEO OF IT AND SO TRUCK DOESN'T EVEN TRY TO START. I TOOK A VIDEO OR THE PROBLEM

THE FRONT PARK ASSIST SENSORS ON THIS TRUCK DO NOT OPERATE AS INTENDED, OR AS ON PRIOR YEARS OR AS ON OTHER VEHICLES. THE SENSORS DID NOT PICK UP PARKING BOLLARDS IN FRONT OF A CONVENIENCE STORE AND RESULTED IN A MINOR DING THAT COST OVER $1300 TO REPAIR. WHEN BUMPER WAS REPAIRED THE SERVICE PERSON SAID SENSORS WERE FIXED, YET, TO HIS SURPRISE, WE WERE ABLE TO INCH UP TO A CAR DIRECTLY INTERSECTING THE FRONT OF THE CAR AND IT DID NOT PICK IT UP. I DID A SIMILAR TEST WITH A BRAND NEW/UNSOLD VEHICLE ON DEALER LOT IND IT FAILED TO SENSE THE LARGE TRUCK DIRECTLY IN FRONT OF IT. THIS I BELIEVE CAN BE A VERY DANGEROUS SAFETY ISSUE AS THE TRUCK HOOD SITS VERY HIGH IMPEDING VIABILITY AND A SMALL PERSON OR PET CAN EASILY GO UNDETECTED. THESE VEHICLES HAS ALSO HAD NUMEROUS RECALLS INCLUDING ONE FOR THE POSSIBILITY OF THE HOOD FLYING OPEN WHILE OPERATING. I HAVE SOLD THE TRUCK AS ALL OF THESE ISSUES HAVE DEVALUED THE VEHICLE, IT REMAINS UNSAFE AND GM RESPONSE HAS BEEN LESS THAN FAVORABLE.

TL* THE CONTACT OWNS A 2020 GMC SIERRA 2500. THE CONTACT STATED THAT WHILE DRIVING, HE NOTICED SMOKE ENTERING THE VEHICLE THROUGH THE AIR VENTS. THE CONTACT COASTED TO THE SIDE OF THE ROAD, EXITED THE VEHICLE SAFELY WITH HIS PASSENGER, UPON OPENING THE HOOD NOTICED THAT THE WHOLE ENGINE COMPARTMENT WAS ON FIRE. THE CONTACT STATED THAT THE FIRE DEPARTMENT ARRIVED BUT WAS UNABLE TO EXTINGUISH THE FLAMES AS THEY ALLOWED THE VEHICLE TO BURN UNTIL THE FIRE SELF EXTINGUISHED. THE DEALER NOR THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 2,800. VIN WAS NOT AVAILABLE.
