Recall N262576260 has just come out. My truck has the same symptoms/conditions consistent with the recall. I have a code P0420, check engine light, high oil consumption and loss of power. also, the GM representative i spoke with told me i have an open recall N242450631. it does not show on the NHTSA website and it does not show at the dealer. the high oil consumption has allowed the turbo to damage the catalytic converter and something in the engine to tap due to less lubrication.

I was driving my truck (2019 GMC Sierra 5.3L) while pulling a travel trailer to go camping. As I was getting onto the interstate, without any prior warning, all at once the truck began to shake, make a concerning noise, and various warning lights began displaying on the driver information panel. I pulled the truck off as safely as possible and had the truck towed to a GM Dealer for service. After investigating the engine, the service department informed me that an exhaust lifter failed, camshaft lobe was damaged, and a cylinder wall was scored resulting in the engine having to be replaced. As this happened while on the interstate with many other passenger vehicles and semis around us, and with the added component of pulling a travel trailer in the moment, my family and myself were in danger of oncoming high speed traffic while getting the hindered truck off of the road, sitting waiting for a tow truck to come, having to unhook the trailer on the side of the interstate and re-hook it up to another truck, and transferring my wife, kids, and myself to another vehicle.

Engine died while on the freeway. Had the truck sent to my dealer via flatbed with AAA. They diagnosed it as the known lifter issue—lifter broke and metal went into the camshaft and scored it. So I need to replace the camshaft and lifters. They’re quoting me $12k for that. I have 83000 miles on this car and I take very good care of it.

Vehicle started running very rough & displaying error codes for "steering assist IS reduced", "service parking brake", and "service esc". while driving vehicle it would accelerate & deccelrate on its own. limped the truck to our local reputable mechanic who ran tests & determined it as an issue with the lifters. it IS known gm IS currently having issues with the 6.2L V8 engines. clearly this issue IS wider spread than the current few years they are admitting to. we are having to have a new engine installed at our expense.

Engine failure. My engine is near failure, loud knocking, check engine light and trusted repair shop analyzed. The repair diagnosis is that the engine will fail in the very near future and that is not safe to drive because of risk of failure. I like the truck and it is still in great condition (129k miles). So, I search for recall information and see the 6.2L 2021-2024 recall and see there is additional investigation underway on newer models. Is it possible it goes back to the redesign of the pick-up in 2019? It sounds like the same issue.

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.

The vehicle has experienced repeated Electronic Stability Control (ESC) malfunction warnings that appear related to a prior GM recall for ESC malfunction codes. These warnings occurred before and after dealer repairs. The ESC malfunction may have affected other safety systems. I was involved in two separate accidents while driving this vehicle, and in both incidents the airbags did not deploy. In one accident, the vehicle struck multiple objects in a frontal collision at significant speed. The airbags did not deploy at all. I lost consciousness, sustained injuries, and have experienced ongoing physical symptoms since the incident. The ESC malfunction warnings continued even after GM dealership repairs following each accident. The defects were not resolved, and the vehicle has remained unsafe and inoperable. The vehicle has been inspected by a GM dealership multiple times, but the issues were not corrected. The ESC malfunction warnings and airbag non‑deployment have been reproduced and confirmed through these service visits. There were warning messages related to ESC malfunction prior to the failures, and these messages continued to appear. The combination of ESC malfunction, loss of control, and airbag non‑deployment suggests a possible cross‑module safety failure involving the airbag system and ESC. I have contacted GM’s corporate safety team and GM’s executive support, but the responses I received did not address the safety‑defect issues. I have sent follow‑up emails and made phone calls but have not received further assistance. The vehicle remains unsafe to operate, inoperable, and available for inspection.

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…
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.

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.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
