The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the vehicle came to a full stop to allow wildlife to cross the road. Upon accelerating, the engine made an abnormal banging noise. The contact stopped to inspect the vehicle and observed an engine misfire while idling. The vehicle was towed to the residence, where an independent mechanic diagnosed that the lifters had collapsed, and that the engine needed to be disassembled for further diagnostic testing. The failure mileage was approximately 159,000.

The backseat middle passenger seatbelt failed to release causing my [XXX] child to become stuck and restrained in the seatbelt blocking his circulation, therefore for the safety of my child I had no choice but to cut the seatbelt. I have tried to report it to the dealership and insurance company but both advised that this is not something that is covered by insurance or warranty. Is this a recall that the manufactory can repair? INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Since I purchased my vehicle in 2021, I continued to have issues with my oil pressure light coming on usually about 2000 - 3000 miles past the oil change. When checking oil, I would find that it was low 2 quarts of oil each time. I reported this to the GM Dealer and they did oil consumption tests and determined the oil loss was within GM tolerances. So apparently it is ok to burn a quart of oil every 1000 - 1500 miles. Then fast forward to January 2025, apparently my rear main seal was blown out. Unfortunately by then my Powertrain warranty had expired. So that cost $3,794. Now fast forward to March 2026, I hear a noise in my engine and notice it is leaking oil again. Upon taking it back to the dealer, they tell me the engine needs replaced or rebuilt. The rear main seal is bad again, a lifter bad and they specifically say "The engine still has excessive blowby due to stuck piston rings or a scored cylinder". This is the first time it was ever reported to me that the engine as blowby. Regardless of all this, I had to replace this engine with less than 117,000 miles on it. I was reporting the oil issue when it was well under the powertrain warranty, but the first Oil Consumption test was done at 51,946. So again under powertrain warranty. However I continued to tell them about it until these issues occurred. Now I have $10,912.75 invested in repairing/replacing an engine. I pushed it to GMC Customer service and they didn't want to help. However when investigating this issue wi

I am writing to formally log a safety concern regarding my vehicle’s 6.2L L87 engine, specifically in relation to the known defects under NHTSA’s ongoing Engineering Analysis EA25007. The engine seized up while driving in traffic which has a safety impact on the occupants and other drivers. The vehicle was towed to GM and the they noted the the engine has catastrophic internal failure with large metal debris in the engine oil and filter. This is consistent with failures that other GM owners have experienced with GM's L87 engine. The initial recall (Recall 25V-274) for a specific manufacturing window (March 1, 2021, to May 31, 2024), the NHTSA launched EA25007 because it continued to receive a flood of complaints from owners whose vehicles fell outside that original recall window. That is me, I am outside that original window. But I am confident that the issue was known by GM and should have been handled several years ago with a wider recall window. Now I was exposed to a safety issue and I am stuck with a large repair bill. I think there is an even broader active investigation EA26005.

I HAD COMPLAINED TO THE DEALER LESS THAN ONE YEAR AFTER PURCHASE IN MAY OF 2019 THAT THERE WAS A SHUDDERING NOISE AND THE TRANSMISSION HESITATES AND SEEMS TO LOCK UP AT TIMES. I WAS TOLD IT WAS "JUST HOW THE 8-SPEED TRANSMISSION OPERATES". IT HAS CONTNUED THROUGHOUT OWNERSHIP AND NOW SEEMS TO LOSE POWER AND VIBRATES EXCESSIVELY DURING ACCELERATION.

I was coming to a stop at a stop a 3 way stop intersection. I parked completely and when I stopped the vehicle just shut down I did not have any warning signs come on prior as I looked at the dash it said place vehicle into park and start. I tried that but truck did not start. Call my friends we towed the truck on a trailer to my house and set up an appointment with gmc here in Tucson az

See attached document for complaint.

My truck is a 2019 6.2 motor GMC it fell outside of the motor recall. On May 23, 2026, I had a catastrophic engine failure. GM would not cover any costs associated with the engine replacement. I have a photo of the failed lifter. This issue is a problem with GM and its active fuel management system. GM knew about the issue and put the engine into service.

Engine went out very devastating $10k out of pocket

2019 GMC Sierra 1500 Denali Ultimate (6.2L L87 V8 Engine)Description of Safety Defect & Incident Chronology: XXX (49,801 miles): While idling in my driveway, the engine began ticking loudly, running roughly, and ultimately stalled. The vehicle was towed to Hight Chevrolet in [XXX]. The dealership stated they test-drove the vehicle twice while monitoring live data, could not duplicate the noise, and released the truck back to me.XXX (57,920 miles): The engine began ticking loudly again. I returned the vehicle to the dealership. Upon inspection, technicians found metal debris in both the oil filter and the oil pan. The dealership diagnosed a catastrophic bottom-end engine failure.Resolution: The original engine was replaced with a GM remanufactured crate engine, covered under the GM factory warranty.Safety Concern:Although my vehicle is a 2019 model, it suffered the exact same catastrophic bottom-end bearing failure currently being investigated by NHTSA for 2021–2026 GM 6.2L L87 engines. This defect poses an imminent safety hazard, as a sudden bottom-end failure can cause the engine to seize without warning, resulting in a complete loss of motive power and propulsion at highway speeds, drastically increasing the risk of a crash. Furthermore, despite GM's claims regarding limited production windows, this case proves the defect is present in earlier 2019 model years.

My 2019 6.2 engine suffered from severe loss of compression caused by internal piston ring failure and bore scoring also loss of power . In the 6.2L engine , piston ring failure and ring- seal are direct consequences of connectiing rod alignment errors, My engine failure is proof that this is the same situation that is currently under investigation and have proof with compression test and report done by my Technician . First time it happened to me it just stopped on me in the middle not the road all lights came on the dash including ESC light something it never done before. But before this happened it had been running rough. I took it first to the local repair shop and they wouldn't be able to work on it , So I took it to the local dealer and there it got. worse from there . Took it to the dealer changed the battery and it was running again but they found it had really bad leak on the rear main seal spent over $3,000 for all of it. Thought the problem was over after that months later after it was running rough again took back to the dealer and from there they told me there were oil coming through the piston rings and metal shaving in the engine and from there found out engine needed to be replaced Warranty company would not cover it. I had to pay 1500.00 for rental car coverage, teardown of engine was 3,500 since the extended warranty did not cover it Endurance Warranty Co. denied my claim.Dealership is charging me out of pocket charges of 13,495 for the engine replacement pl

Truck has the 6.2 Litre engine,failed.GM won't do anything to fix or replace the engine.

Several months ago while having my truck serviced, I asked the repair shop to inspect the ball joints on the passenger side because they would make a popping noise when turning the wheel. The shop inspected them and said that was a normal sound due tot he factory lift. Recently I was driving home and about to turn into my lane when the front passenger wheel assembly collapsed under the truck due to the a upper ball joint failure separating the brake line and loss of steering. At the time, I was only going about 25mph and the truck slid to a stop on its own. The truck has 65,000 miles on it and if this had happen at highway speeds personal injury to myself and others would have been likely. The repair cost were $7,500. Fortunately I purchased an extended warranty which covered all but $1,700 of the repair.

The contact owns a 2019 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the accelerator pedal was depressed and the vehicle started jerking and shaking before unintendedly accelerating. Additionally, the vehicle jerked and started to lose motive power. The dealer was contacted; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 108,000.

On XXX at approximately 3:00 p.m., I was driving on the highway in [XXX], at approximately 65 mph when my truck suddenly displayed a warning stating that all oil pressure had been lost and that the engine needed to be shut off immediately. Within roughly seven seconds of seeing and comprehending the warning, I attempted to safely shut down the engine. Before I could do so, the engine seized while the truck was still traveling at highway speed.The engine failure caused an immediate loss of power steering and power-assisted braking, leaving me with limited control as the truck coasted at highway speed. This was an extremely dangerous situation that could have resulted in a serious accident, injury, or loss of life. The truck was towed to a repair facility, where technicians confirmed that the engine had seized and recommended replacing the long block. A new GM Genuine Parts engine was installed, and the repairs were completed on XXX. Today, XXX, the replacement engine has approximately 40,000 miles on it. I recently began hearing a ticking noise followed by knocking, and the engine nearly stalled while idling. I immediately checked the oil and confirmed that oil was present on the dipstick. I have consistently maintained the vehicle and completed every oil change at intervals of 5,000 miles or fewer. I returned the truck to the same repair facility that installed the replacement engine and was immediately informed that the truck requires yet another engine replacement. This is

Engine seized on June29th while driving on I 64 . (6.2 L87) due to oil line failure. Engine replaced on July 18th, 2026. New engine started leaking oil from camshaft and gasket on August 10th 2026, back in GMC Shop on August12th 2026 for repairs, still waiting parts today. Sudden failure on road in traffic Inspected by GMC Southpoint. No indication prior to failure and shut down completely. Could not do anything to move vehicle out the road.

My 2019 GMC Sierra 1500 AT4 equipped with the 6.2L engine experienced an internal engine/lifter failure. The vehicle was inspected by an authorized GMC dealership. The dealership documented damaged lifters, including rough edges and visible signs of friction, and advised that the camshafts on these vehicles can also have issues. I was provided estimates for both a lifter repair and complete engine replacement. Due to the possibility of additional internal engine/camshaft damage and the risk of having to repeat the lifter repair, complete engine replacement was recommended. The dealership is replacing the engine with a GM remanufactured engine, part #19420611, carrying a 3-year/100,000-mile warranty. The customer-paid repair is approximately $9,400 plus applicable taxes and shop charges because my 2019 vehicle/VIN is not currently included in the existing L87 engine recall. I am submitting this complaint because NHTSA is currently investigating failures involving 6.2L L87-equipped vehicles outside the existing recall population. I believe this failure should be documented and considered as part of the investigation into whether the affected vehicle population should be expanded. I have requested the dealership provide the technician's complete diagnosis and documented cause of failure and can provide additional information when received.

There was a catastrophic internal engine failure, due to cam/lifter/bearing issues. This caused the timing chain and tensioner to jump and the engine to be out of alignment. This caused the valves to all be bent as a result. I believe that this has been an issue for longer than what GM has originally recalled for, and I am submitting this complaint because I read that there is an active investigation into this.

At approximately 85,000 miles, the engine in my 2019 GMC Sierra 1500 seized. The vehicle was parked when it occurred. This created a safety risk because an engine seizure can cause sudden loss of propulsion in traffic. Before the failure, I didn't notice anything that would raise any alarms. The problem was inspected and confirmed by a GMC dealer, which diagnosed the condition as an engine seizure. The failed engine is not available for inspection. I am not aware of the precise internal cause beyond the dealer’s diagnosis.
