General Motors (GM) is recalling certain 2019-2021 GMC Sierra 1500 and Silverado 1500 vehicles equipped with certain accessory road tires and a 17" spare tire. The 17" spare tire provided with the vehicle is not compatible for use with the accessory wheels, which can cause the anti-lock brake system (ABS) to not function properly under certain conditions.
An ABS system that does not function properly can increase the risk of a crash.
Dealers will provide a new 17" spare tire and wheel assembly that is compatible with the accessory wheels, free of charge. Dealers will also apply a new spare tire information label, and provide owners with an owner's manual insert clarifying which spare tire to use with the accessory road tires and with the 17" original tires.

6.2 liter engine failure @ just over 100,000 miles. Prior to 100k miles I had taken to the dealership for sporadic loss of oil. They confirmed that the oil had been upgraded previously as instructed by GM so must be another source of the leak. Engine locked up while driving down the road. Had to have the vehicle towed and the mechanical said the motor is shot, and related to lower camshaft bearing issue. The only warning signs were the low oil light which happened around the mid 90k miles, so I would monitor that. When the engine failed there was no low oil light on, it just started shaking/vibrating and then kicked out. I think hte mileage read right around 103,000 approx. when it died.

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 with other mechanics, they all seem to know about all the issues these L87 engines have. Then I found out that 2021 - 2024 L87 engines were recalled, but my 2019 was not. It appears my engine has similar issues as the recall. I was just lucky enough that nothing happened while I was driving. So I asked that if a recall occurs that GMC should be responsible for refunding all of this money as they should have taken care of it when I told them 100,000 miles ago.
Engine, Sep 10, 2026
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.

Engine went out very devastating $10k out of pocket
Engine, Aug 30, 2026
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 plus engine teardown Endurance Warranty Co. denied my claim. Even after paying for warranty for almost 2 Years. GM says manufacture warranty is out of coverage can not be apart of the recall but engine failure mirrors 21-24 recall 6.2 engines.

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.

On [ADD DATE] while driving 40-45 mph westbound on [XXX] near XXX in [XXX], in a school zone, the engine suffered sudden catastrophic internal failure with complete loss of propulsion and would not restart. No prior warning lights or low oil pressure warning. Vehicle required tow from school zone. GMC dealer inspected and verified catastrophic internal failure. Dealer stated verbally failure is either camshaft broken in half or timing chain sprocket/pulley broken off or loose causing timing chain to come off. Timing cover was not removed to confirm. Dealer stated engine is not repairable and quoted $13,500 for new engine replacement only. I have copies of the work order and the dealer's written statement verifying internal failure and replacement recommendation. Engine and vehicle have been retained.

Engine, Aug 19, 2026
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 now the second 6.2L L87 engine that has failed in this vehicle. Two catastrophic engine failures—one involving a replacement GM Genuine Parts engine after only approximately 40,000 miles—are completely unacceptable. The first failure created a severe highway safety hazard, and the failure of the replacement engine raises serious concerns about the reliability and safety of these engines.

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. Inability to start. This created a safety risk because an engine seizure can cause sudden loss of propulsion in traffic. Before the failure, I did not notice any red flags. 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.

Complete failure on Cylinder 3 after AFM system caused lifter collapse in 5.3L V8. Lifter fell into cam shaft and scored the shaft at 55mph. Truck started surging and shaking violently. Truck shaking had me swerve to the side of the road as I was coming up on a crosswalk with golf cart about to cross the road. Vehicle was inspected at Atwater GM in Aitkin, MN and component failure was identified. Two weeks later I paid $14,149 to have a complete engine replacement. There was absolutely no indication that this event would take place. Just months before I took this truck from [XXX] to [XXX] and back without an issue. GM should be held responsible for a complete lack of safety due to faulty AFM engines. Not only did this endanger my safety, but I also had to withdraw from my 401k to pay for the outrageous cost of a new engine replacement because of a single point of failure.
