2020 GMC SIERRA 1500 Complaints

MY TRUCK TUESDAY MARCH 16TH HAD ME UPDATE SOFTWARE AS SOON AS I GOT TO WORK, AFTER IT WAS DONE I GOT OUT OF MY TRUCK AND IT WOULD NOT LOCK WITH PUSH BUTTON OR FOB. WHEN I GOT INTO MY TRUCK TO GO HOME 10HRS LATER IT MADE A BUNCH OF CLICKING NOISES AND AFTER A MINUTE IT SHOWED UPDATE COMPLETE ON SCREEN THEN STARTED. THE VERY NEXT DAY I DROVE BACK TO WORK WHICH IS 22 MILES. WHEN I TOOK MY TRUCK TO LUNCH THREE BLOCKS AWAY I HAD ESC SERVICE LIGHT AND SERVICE PARKING BRAKE ACCOMPANIED BY CHECK ENGINE LIGHT. I CALLED LOCAL DEALERSHIP TO GET IT LOOKED AT AND THEY SAID FRIDAY WAS AS EARLY AS I COULD GET IT IN. I LEFT WORK EARLY AT 1:30 AND TRIED TO DRIVE IT AND IT WAS SQUALENE LIKE A BAD POWER STEERING PUMP AND SHAKING AS I DROVE. I WENT AHEAD AND TOOK IT THE DEALER.

2020 GMC SIERRA SLT VIN:[XXX] 15,700 MILES. BRAKING SYSTEM FAILURE AT ABOUT 45MPH ON HIGHWAY 78 IN LOGANVILLE, GA APPROACHING AN INTERSECTION WITH RED LIGHT, VEHICLE SEEMED TO LOOSE ALL POWER BRAKING. I STOOD WITH ALL I COULD ON THE PEDAL, AND TURNED TO AVOID REAR ENDING STOPPED VEHICLES, RUNNING INTO MIDDLE OF THE INTERSECTION BEFORE IT STOPPED; NO ACCIDENT ! DEALER IS REPLACING MASTER CYLINDER AND BOOSTER BRAKING SYSTEM, ALONG WITH COMPUTER SYSTEM UPGRADE. MY CONCERN IS THE DEALERSHIP AND NHTSA IS AWARE OF THIS ISSUE, YET NO CEASE AND DESIST DRIVING DIRECTIVE HAS BEEN ISSUED ! INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

WHEN STATIONARY AND PREPARING TO START VEHICLE INTERMITTENTLY SEE "SERVICE STEERING COLUMN LOCK" MESSAGE APPEARS AND DISAPPEAR ONCE VEHICLE IS STARTED. THIS WAS PREVIOUSLY SUPPOSED TO BE ADDRESSED WITH SERVICE BULLETIN 20-NA-21 HOWEVER BEING TOLD BY SERVICE DEPARTMENT THAT VEHICLE HAS ALL CURRENT UPDATES APPLIED A YEAR AGO, INCLUDING THE ONE THAT SHOULD OF ADDRESSED THE ISSUE. TOLD THAT THE VEHICLE HISTORY SHOWS RECORDS OF PAST "LOSS OF COMMUNICATION TO DIC" BUT AS THEY CAN'T IMMEDIATELY REPRODUCE NO ACTION WAS TAKEN.

DANGEROUS VISIBILITY HAZARD WHEN BACKING UP VEHICLE AT NIGHT. INFOTAINMENT SCREEN SWITCHES TO "FULL BRIGHTNESS" WHEN BACKUP CAMERA IS ACTIVATED, RESULTING IN BLINDING LIGHT TO DRIVER. DRIVER CAN NOT BACKUP SAFELY WITHOUT PHYSICALLY COVERING THE SCREEN TO REGAIN VISIBILITY. SCREEN BRIGHTNESS REFLECTS OFF ALL 4 WINDOWS, WINDSHIELD AND BACK GLASS. SIDE MIRRORS ARE UNUSABLE IN THIS CONDITION. THERE WAS A FIX FOR THIS ISSUE ON PREVIOUS GM MODELS, (PRIOR TO 2018), HOWEVER NO FIX FOR 2019 - PRESENT

THE STEERING WILL COMPLETELY LOCK UP, THIS IS THE 2ND OCCURRENCE. IT WAS AT THE DEALER 1143 MILES AGO AND CODES WERE CLEARED, PROBLEM REOCCURRED. I WAS ABLE TO START THE VEHICLE, PUT IN DRIVE/REVERSE NEUTRAL ETC WITHOUT ISSUES, HOWEVER THE STEERING WAS COMPLETELY LOCKED UP AND WOULD NOT ALLOW STEERING/CONTROL OF THE VEHICLE. THE VEHICLE WAS PARKED IN DRIVEWAY, COLD OUTSIDE BOTH TIMES. I HAVE VIDEO EVIDENCE. THE FIRST OCCURRENCE 12/26/2020 AT 9591 MILES, 2ND OCCURRENCE 2/16/2021 AT 10733 MILES (1142 MILES LATER)

WHILE DRIVING ON A STATE HIGHWAY, I HEARD A "POP" SOUND, I SAW NOTHING CONTACT THE VEHICLE, BUT I THEN NOTICED THE WINDSHIELD WAS CRACKED. THE WINDSHIELD CRACKED FOR NO APPARENT REASON..

AT ABOUT 3500 MILES LIFTERS ON TWO CYLINDERS COLASPED. TOOK TO DEALER THAT DEALER HAD THREE WEEKS BUT FIXED IT. 1500 MILES LATER AT 5036 MILES IT HAPPENED AGAIN ON A DIFFERENT CYLINDER. NUMBER 8. THE FIRST TIME IT WAS 3 AND 5. THE FIRST TIME THE DEALER REPLACED ALL 8 CYLINDERS. SO CYLINDER NUMBER 8 WAS NEW AS WELL. GMC HAS SAID THERE IS NOTHING ELSE THAT CAN BE DONE TO FIX THE ISSUE. THE SECOND DEALER SERVICE MANAGER STATES THAT HE WOULD NOT TRUST IT EITHER TO GO ANY LONG DISTANCE . ALSO STATED THAT THEY HAVE PUT 3 SETS IN TO ONE VEHICLE BEFORE. AS AN ASE MASTER CERTIFIED TECHNICIAN I FIND THIS DISTURBING. I ALSO WAS A GMC,PONTIAC, OLDSMOBILE MASTER TECHNICIAN. THIS IS UNEXCEPTABLE FOR GM TO THINK THIS IS OK TO TAKE PEOPLE'S HARD EARN MONEY AND NOT FIX THERE ISSUES OR MAKE IT RIGHT. I OWNED A 2014,2016,2018 SILVERADO'S THAT HAD NO ISSUES WHAT SO EVER. TO MAKE THINGS WORST GMC ROAD SIDE ASSISTANCE FORGOT ABOUT THE TRUCK BROKE DOWN IN 7 DEGREE WEATHER WITH 35 MILE AN HOUR WINDS. FOR OVER 24 HOURS AND SEVERAL CALLS BACK TO FINALLY GET A SUPERVISOR TO SPEAK TO. TWO DEALERS SAY THAT IT IS UNACCEPTABLE EXCEPT THE CURRENT DEALER THAT IS DEALING DIRECTLY WITH GMC. ANYONE CAN DO A SEARCH ON GM TRUCK LIFTERS COLLAPSING AND YOU IMMEDIATELY OVERWHELMED WITH INFO. IT IS ALSO DISTURBING THAT A DEALERSHIP SERVICE MANAGER SAYS WE COULD PUT A NEW ENGINE IN AND THE SAME THING COULD HAPPEN. THAT TO ME IS POOR QUALITY CONTROL AND POOR CUSTOMER SERVICE. I HAVE ALWAYS BEEN A GM ENTHUSIASTS BUT THIS WILL BE MY LAST ONE. HORRIBLE CUSTOMER SERVICE AND DO NOT BUILD A GOOD PRODUCT OR STAND BEHIND IT. GM SHOULD BE ASHAMED OF THERE FALL FROM GRACE. THIS ALL HAPPENED JUST DRIVING ONCE TO WORK AND ONCE HAULING A ATV ON A TRAILER.

WIPERS FROZE TO WINDSHIELD WHILE DRIVING WITH DEFROSTER ON MAX. DESIGN OF THE WINDSHIELD AND DASH MEANS WIPERS SIT LOWER THAN WHERE THE DASH AND WINDSHIELD MEET, AND NO WARM AIR FROM THE DEFROSTER CAN GET TO THE WINDSHIELD WHERE THE WIPERS SIT. THERE IS NO IN WINDOW DEFROSTER (LIKE REAR WINDOW) WHICH CAN HELP. MAJOR SAFETY ISSUE IN SNOW/ICE CONDITIONS.
