2019 GMC SIERRA 1500 Complaints

Purchesed a 2019 GMC AT4 6.2 w/16300 miles on it on April 19, 2021. Yesterday w/18700 miles are began to exprience a loud ticking sound coming from my engine. The ticking is associated with a failed lifter or lifters. Had to get my truck towed to the dealership for repair.

Vehicle was 300 miles out of warranty when I get a service trailer brake warning on my info center replaced a blown fuse and the fuse blows again, no trailer has ever been hooked up to this truck. Went online and inquired about this problem and there's thousands of post and complaints about this problem, even on a GM site there's a PI investigation about this problem, why doesn't GM just do a recall to fix a problem they know about. I'm getting ready to buy a travel trailer and now I don't know if its safe to pull it!

I RECEIVED A BRAKE CONTROL MODULE WARNING ALERT. THE ALERT INDICATED MY ABS SYSTEM WAS SUBJECT TO FAILURE AND REQUIRED A SOFTWARE PATCH. I SEE THAT THE EXACT ISSUE I HAD WAS SUBJECT TO A RECALL OF 463,000 SIMILAR YEAR AND MODEL VEHICLES. DESPITE THE IDENTICAL ISSUE, IT BEING RELATED TO A FAILURE OF THEIR SOFTWARE THE GMC WEBSITE AND MY DEALER REFUSED TO COVER MY VEHICLE CLAIMING IT WAS NOT PART OF THE RECALL

TL*THE CONTACT OWNS A 2019 GMC SIERRA 1500. THE CONTACT STATED WHILE DRIVING 30 MPH, THE BRAKE PEDAL WAS DEPRESSED TO THE FLOOR BUT FAILED TO STOP THE VEHICLE. THE VEHICLE DROVE THROUGH A RED TRAFFIC LIGHT. THE CONTACT STATED NO WARNING LIGHT WAS ILLUMINATED. THE CONTACT STOPPED THE VEHICLE WHILE USING THE PARKING BRAKE. THE VEHICLE WAS TAKEN TO JACK GIAMBALVO BUICK GMC (1390 EDEN ROAD, YORK, PA 17402, (717) 781-2154) AND THE DEALER WAS MADE AWARE OF THE FAILURE. THE CONTACT STATED THE VEHICLE WOULD BE TOWED TO KOONS CLARKSVILLE CHEVROLET BUICK GMC (12421 AUTO DR, CLARKSVILLE, MD 21029: (410) 988-9522) TO BE SERVICED WHICH WAS STILL PENDING. THE VEHICLE WAS NOT YET DIAGNOSED NOR REPAIRED. THE MANUFACTURER WAS NOT INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 13,000.

TRANSMISSION SHAKES RATTLES AND JERKS AND HAS SINCE I GOT IT BRAND NEW. INTERMITTENT ISSUE NORMALLY BUT SOMETIMES IT'S EXTREMELY AGGRESSIVE AND LEGITIMATELY CAUSES A WHIPLASH MOTION

TRANSMISSION FEELS SLUGGISH AND JERKS. WHEN COMING TO A STOP FEELS LIKE YOUR BEING REAR ENDED. STEREO SYSTEM FREEZES AND GOES SILENT NO SOUND WHAT DO EVER

ON SATURDAY, FEBRUARY 27, 2021, MY HUSBAND (DRIVER) AND MYSELF (PASSENGER) WERE TRAVELING ON A SAINT LOUIS HIGHWAY AND THE REAR PASSENGER TIRE SUDDENLY BLEW WITH NO WARNING. THERE WERE NO TIRE PRESSURE OR OTHER WARNINGS DISPLAYED ON THE DASH OF THE TRUCK. AFTER PULLING OVER, WE DISCOVERED THE ENTIRE SIDE OF THE TIRE HAD COMPLETELY BLOWN (LARGE HOLES OVER THE ENTIRETY OF THE WALL OF THE TIRE). IT WAS NOT UNTIL A MINUTE OR TWO AFTER THE TIRE BLEW THAT THE TRUCK DISPLAYED A LOW TIRE PRESSURE WARNING. AFTER RESEARCHING THE TIRE MAKER'S WEBSITE, I DISCOVERED A RECALL FOR THE EXACT TIRE HOWEVER, THE DATE AS LISTED ON THE DOT NUMBER WAS ONE WEEK OFF. OUR TIRES SHOULD HAVE ALSO BEEN INCLUDED IN THE RECALL AS THE DESCRIPTION OF THE TIRE MAKER'S DEFECT WAS EXACTLY AS IT OCCURRED WHEN OUR TIRE BLEW OUT.

WHEN I GO OVER CERTAIN HUMPS IN THE ROAD WHILE GRASPING THE STEERING WHEEL WITH BOTH HANDS, THE STEERING WHEEL SLIPS OUT OF ITS LOCKING POSITION AND SHIFTS UP AND DOWN AS I PASS THRU THE HUMP. I HAVE OWNED THE VEHICLE 3 MONTHS AND HAS HAPPENED ON TWO OCCASIONS. WHILE MY VEHICLE IS COVERED BY WARRANTY (SO NOT LOOKING FOR ANY MONETARY COMPENSATION) IT ALMOST CAUSED ME TO LOSE CONTROL OF MY VEHICLE AND SEEMED LIKE A POTENTIAL HAZARD FOR OTHER DRIVERS.

2019 GMC SIERRA WITH 56K MILES WHEN ACCELERATING TRANSMISSION SEEMS TO GET STUCK IN FIRST GEAR MAKES IDOL SOUNDS RPMS JUMP UP THEN HARD SHIFT INTO SECOND, MAKES THE TRUCK JERK WHEN IT HAPPENS, SINCE THE ISSUE STARTED IT HAPPENS EVERY TIME I DRIVE IT. I TOOK IT TO LOCAL GMC DEALERSHIP ON 2/9/21 MANAGER SAID 'YES IT'S A KNOWN ISSUE WITH GMC & THAT YEAR MODEL TRUCKS' 2 DAYS LATER CALLED TO SEE STATUS OF TRUCK MANGER SAID HIS TRANSMISSION GUY FOUND THE ISSUE AND FIXED IT SAID COMPUTER AND TRANSMISSION NOT TALKING TO EACH OTHER DID A 'TRANSMISSION RELEARN' WAS COVERED UNDER POWER TRAIN WARRANTY. I HAD THE TRUCK BACK LESS THAN 24 HOURS AND NOW BACK TO HAVING THE SAME ISSUES AGAIN! CLEARLY IT'S NOT FIXED AND CONCERNING THIS IS GOING TO BE A SAFETY ISSUE WHILE DRIVING! GMC 'KNOWN' ISSUE THEN ISSUE A RECALL AND FIX IT RIGHT THE FIRST TIME!
