L87 Catastrophic Engine Failure on second engine after 6300 miles. This is the second issue with the 6.2L engine in my Sierra 1500. The first engine passed the L87 Engine Loss of Propulsion field action and then suffered Catastrophic Engine Failure a month later. The replacement engine procedure took over 3 weeks to perform and no rental or loaner vehicle was provided by GM or the servicing dealership. The vehicle is currently in the service department at another dealership awaiting the 2nd engine replacement, but it has been over 2 weeks since the engine failure. This servicing dealer has provided a vehicle to use. This has been a very frustrating ordeal and I feel that resell and value of this vehicle has been compromised and GM has done nothing to offset this with me.
The vehicle is subject to Safety Recall N252494001 (NHTSA Campaign 25V-274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • Component/System Failed: The 6.2L V8 (L87) engine crankshaft and connecting rod assembly.

The vehicle is subject to Safety Recall N252494001 (NHTSA Campaign 25V-274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • Component/System Failed: The 6.2L V8 (L87) engine crankshaft and connecting rod assembly. The engine is available for inspection upon request. • Safety Risk: The defect can cause catastrophic engine damage and sudden loss of propulsion while driving, significantly increasing the risk of a crash. • Dealer/Manufacturer Confirmation: The problem was confirmed via the issuance of Safety Recall N252494001. A dealership inspection was performed previously as part of the recall. • Warning Signs/Symptoms: Common symptoms include engine knocking, check engine lights, and hesitation before sudden failure. The Issue with the Remedy: Federal law (49 U.S.C. § 30120) requires manufacturers to remedy safety defects "without charge". As a permanent safety remedy for this defect, GM has mandated a switch from 0W-20 to 0W-40 (dexosR) oil for the life of the engine to prevent bearing failure. However, the dealership and manufacturer are refusing to provide this mandated safety spec change without an ongoing $85 surcharge per oil change. While they performed the initial "inspection" oil change for free, they are now using the recall-mandated spec change to create a financial burden on the consumer. Because 0W-40 is now the mandatory factory requirement to prevent the safety defect, charging a premium for it constitutes a failure to provide the recall remedy "without charge." General Motors refuses to offset this cost, effectively penalizing the owner for a manufacturer safety defect. The dealership is also failing to honor my Platinum Wrap warranty and GM Prepaid service contract to perform the continued oil changes without additional charges.
While driving I get a reduced acceleration warning on my dash cluster, drastically reducing horse power. My check engine light came on. This has happened before. I checked the code and it was a P1098 code. After researching I found out it was the Engine coolant control valve. My fan is constantly running. This issue is ongoing.…

While driving I get a reduced acceleration warning on my dash cluster, drastically reducing horse power. My check engine light came on. This has happened before. I checked the code and it was a P1098 code. After researching I found out it was the Engine coolant control valve. My fan is constantly running. This issue is ongoing. This seems to be a common occurrence with my vehicle year.

My GM Dealership completed the GM 6.2 Engine Inspection and recommended Oil Replacement as part of the 6.2 Engine Recall. Roughly 5,000 miles after this service, the engine failed. I attempted to accelerate from 45-65 miles per hour while getting on the highway, and the engine seized up. I was able to coast/steer the vehicle to the side of the road. The vehicle's starter could not crank the engine. I had the vehicle towed to the shop where the dealership confirmed the engine had seized. The dealership and GM replaced the engine under a warranty repair. I am making you aware of this situation, as the manufacturers suggested solution to the engine issue (The Change in Oil Type, Filter and Cap) did not prevent the engine from failing.

To start off my truck has been to the dealership multiple time for the camera. After third time in the shop they fixed that issue. Then the infotainment started acting up after about 4 times in the shop it was fixed. They gave me the prescribed fix for the engine recall in november. Engine passed the test. Then 3 weeks ago the engine siezed up from the crank and bearings on the interstate doing 70 pulling a trailer in traffic. Leaveing me and my dad in the middle of the interstate. I had to have it towed 2 hours to my house. After the prescribed engine fix. They replaced the motor in 3 days. Great right? No they did not test drive long enough. Or they would have felt the shudder that developed after the new engine went in. It is now about to go back to the shop. Because of the shudder at low rpm and im haveing electrical issues again as well . My remote start also stopped working after the engine replacement.
I purchased my vehicle in June 2025. In January of 2026 the vehicle would sometimes shut down at red lights, requiring me to restart. No engine codes would pop up. On Jan. 16th, 2026, I exited my vehicle and heard a “cow bell clunking” coming from the engine area. I scheduled a service, and I was informed that the issue was part…

I purchased my vehicle in June 2025. In January of 2026 the vehicle would sometimes shut down at red lights, requiring me to restart. No engine codes would pop up. On Jan. 16th, 2026, I exited my vehicle and heard a “cow bell clunking” coming from the engine area. I scheduled a service, and I was informed that the issue was part of the GM recall for 6.2L engines. This concerned me, because my vehicle had already had the “remedy” for the recall (changing engine oil type) prior to me purchasing it Certified Pre-Owned, and the engine still failed. The dealer I brought the truck to did a full engine (and appropriate parts) replacement as part of the open recall.

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.
