STEERING
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)

UNKNOWN OR OTHER
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.

ENGINE
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.

SERVICE BRAKES
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.

VISIBILITY/WIPER
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.

STEERING, SUSPENSION, WHEELS
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.

ENGINE, FORWARD COLLISION AVOIDANCE: WARNINGS, LANE DEPARTURE: ASSIST
WITHIN 3 MONTHS (<4000 MILES) FROM PURCHASE VEHICLE BEGAN SPUTTERING WITH HESITATION, AND TICKING NOISE FROM ENGINE WHILE IN MOTION FOLLOWED BY MULTIPLE ALERTS POSTING ON DRIVER DISPLAY. VEHICLE DISPLAYS LOSS OF POWER, AND STRUGGLES TO KEEP UP WITH TRAFFIC. CHECK ENGINE LIGHT FLASHING FOLLOWED BY CONSTANTLY STAYING ON, SERVICE ESC SYSTEM ACTIVATED, SERVICE PARKING BRAKE, AND STEERING ASSIST REDUCED DRIVE WITH CAUTION LIGHTS ALL ACTIVATED DURING THIS EPISODE. DEALER WORKED ON VEHICLE ENGINE ( AND COMPLETED ON OR AROUND 1/08/2021), AND REPLACED LIFTERS, AND OIL CONTROL VALVE. ON 01/13/2021 NOTICED THAT VEHICLES LANE KEEP ASSIST IS NOW WORKING SPORADICALLY, WILL NOT ACTIVATE CONSISTENTLY WHEN VEHICLE VEERS OFF THE PROPERLY MARKED LANES ON HIGH-WAY/ROADS, AND INCONSISTENTLY ALERTS DRIVER WHILE IN MOTION. THE LANE KEEP ASSIST IS SUPPOSE TO CORRECT STEERING, BUT THIS DOES NOT HAPPEN CONSISTENTLY. THE COLLISION ALERT SYSTEM DOES NOT ACTIVATE OR WORK CORRECTLY. NOTICED WHILE DRIVING THAT VEHICLES IN FRONT ARE NOT DETECTED CORRECTLY, AND INFORMS THE DRIVER THEY ARE WITHIN SAFE DISTANCE (GREEN THIS SUDDENLY CHANGES TO YELLOW). IN ADDITION WHEN VEHICLES IN FRONT APPLY BRAKE, THE COLLISION ALERT SYSTEM DOES NOT ALERT AS IT IS SUPPOSED TO, IT STAYS IN GREEN EVEN AT EXTREMELY CLOSE RANGE. SAFETY MECHANISMS DON'T APPEAR TO WORK CORRECTLY, AND DETECTS ITEMS THAT ARE NOT PRESENT. NOTICED THAT VEHICLE DETECTS LANES EVEN ON UNMARKED ROADS, AND THE FRONT PEDESTRIAN ALERT SYSTEM ACTIVATES SPORADICALLY EVEN IF NO PEDESTRIANS ARE IN FRONT OF VEHICLE WHILE DRIVING. CONCERNED ABOUT SAFETY FEATURES LEADING TO HAZARDOUS DRIVING CONDITIONS.

ELECTRICAL SYSTEM, STEERING
ON DECEMBER 14, 2020 MY SIERRA WITH 2339 MILES DISPLAYED, AT STARTUP, THE POWER STEERING WAS OUT, TO DRIVE WITH CARE. ALSO DISPLAYED SERVICE ESC AND TRACTION CONTROL FAILURES. I DROVE WITH MUCH DIFFICULTY, WITHOUT POWER STEERING, TEN MILES TO THE NEAREST GMC DEALERSHIP, LAFONTAINE IN HIGHLAND, MI. I PICKED UP THE VEHICLE ON DECEMBER 29, 2020 WITH AN ADDITIONAL 60 MILES. THE SERVICE PERSONNEL SAID THEY WERE UNABLE TO DUPLICATE THE PROBLEM, THEREFORE NO REPAIRS WERE MADE. LAFONTAINE HAD CONTACTED GENERAL MOTORS TECH CENTER WHO OFFERED NO SOLUTIONS OTHER THAN CHECKING THE BATTERY AND WIRING HARNESS CONNECTIONS. THE PROBLEM HAS NOT REAPPEARED IN THE FIFTEEN DAYS SINCE I PICKED UP MY VEHICLE.

SERVICE BRAKES, POWER TRAIN
CAR WAS IDLING AND PARKED. WARNING CODE SHOWED UP ON DASHBOARD ESC, ELECTRONIC STABILITY CONTROL, REDUCED ENGINE POWER. VEHICLE THEN DISPLAYED TRANSMISSION DISRUPTION, WARNING LIGHT DISPLAYED AS WELL. I WAS ABLE TO DRIVE IT TO THE DEALERSHIP BUT THE PERFORMANCE OF THE VEHICLE WAS LIMITED BY THE REDUCED ENGINE POWER. TRANSMISSION WAS HESITATING AND CLUNKY DURING GEAR CHANGES. MY SIERRA HAS 5,000 MILES ON IT AND THE TRANSMISSION WAS ALREADY REPLACED AT 2,000 MILES. GMC HAS A SERIOUS PROBLEM WITH THIS MAKE AND MODEL. UNSURE WHAT THE RESOLUTION WILL BE, BUT I AM NO LONGER CONFIDENT IN THE PRODUCT GMC IS SELLING.

SERVICE BRAKES, ELECTRICAL SYSTEM
ON TWO SEPARATE OCCASIONS, THE TRUCK HAS BEEN DEAD WHEN ATTEMPTING TO CRANK. THERE WERE NO LIGHTS OR DEVICES LEFT ON AFTER THE PREVIOUS TIME THE TRUCK HAD BEEN USED. SOMETHING IS DRAWING POWER FROM THE BATTERY CAUSING IT TO BE DEAD. AFTER RECHARGING THE BATTERY, THE CHECK ENGINE CODES READ THAT THERE IS A PROBLEM WITH 'BRAKE LIGHT ILLUMINATION.' HELP IN DETERMINING WHA T IS CAUSING THE BATTERY TO DIE ON SUCH A NEW VEHICLE WOULD GREATLY APPRECIATED! I'M UNCERTAIN AT THIS TIME AS TO WHETHER OR NOT THE BRAKE LIGHT ILLUMINATION IS CAUSING A SAFETY HAZARD.

AFTER HAVING ALL SORTS OF WARNINGS OVER TIME LIKE "SERVICE ESC," "SERVICE PARKING BRAKE," AND MORE, I NOW SEE "BRAKE SYSTEM FAILURE: 62 MPH TOP SPEED" FLASH ACROSS MY DASH. I AM READING AND HEARING THAT THIS IS A VERY DANGEROUS PROBLEM. NEW TRUCK. BRAND NEW. HAD IT LESS THAN A YEAR. BRAKE MESSAGE ALWAYS ON START UP.

ELECTRICAL SYSTEM
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.

ELECTRICAL SYSTEM, ENGINE
THERE IS NO WAY TO PERMANENTLY DISABLE THE AUTO START STOP ON THE VEHICLE. SEVERAL OTHERS HAVE COMPLAINED ABOUT THIS, NO RESPONSE FROM GM. THERE NEEDS TO BE A FIRMWARE UPGRADE TO THE ECM TO ALLOW THE OWNER MAKE THE DECISION ON IF THAT IS ENABLED OR DISABLED. ON MINE, I HAVE TO PUSH A BUTTON EACH TIME I START THE ENGINE TO DISABLE THAT. SOME GM VEHICLES DON'T HAVE THAT OPTION.
