“Total engine power loss while driving 70mph on the highway in steady moving traffic causing a safety hazard, with 3 young children in the vehicle. No prior warning lamps, messages or symptoms to indicate a problem. Engine completely shut down while driving and will not turn back on. Had vehicle towed to the dealership. Certified GMC dealership did a full inspection and indicated that the engine assembly needs to be fully replaced. NHTSA Campaign 25V274 for vehicles 2021 and newer is for the same exact engine failure issue with the same engine size. I would appreciate you exploring the possibility of covering this catastrophic malfunction as an exception to the aforementioned recall campaign. Many other drivers have noted the same failure with the 2019 as was included in the recall for 21-24. Thank you for your consideration, please feel free to reach out to me directly to discuss further. I look forward to hearing from you!”

“On [XXX], my 2019 GMC Sierra 1500 Denali equipped with the 6.2L engine suffered a sudden loss of power while driving. The vehicle lost propulsion and could not continue operating normally. The vehicle was taken to Orange Buick GMC in Orlando, Florida. The dealership advised that the engine is locked and unable to rotate manually, and that the engine requires replacement. The vehicle has approximately 126,000 miles. This failure occurred while the vehicle was being driven and created a safety concern due to sudden loss of propulsion. A sudden engine lockup or loss of power could increase the risk of a crash, especially if it occurs in traffic, at highway speed, while turning, or while crossing an intersection. There was no crash, fire, injury, or death. The vehicle remains at the dealership awaiting repair. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)”

“On May 27, 2026, I was on my way home from work when I went to accelerate the vehicle and all the sudden it started shaking and the check engine light came on with the EBS. I was able to get the vehicle to a repair shop local the next day, who took the car apart. What was thought to be an easy fix of spark plugs and fuel injector, became even more after they put back together and the cylinder was still misfiring. After several hours of taking apart the engine, the mechanic determined that the hydraulic valve lifters had failed. This has been an ongoing issue with with the 5.8L V8. Due to a recall not being under the vin yet, i have now incured a $16k expense to add an engine to it after i purchased it in Nov of 25 at $97,000. This is a saftey issue and luckily no one was hurt when the car started shaking and couldn't go over a certain speed. I want this reviewed and looked at for possible reimbursement as there have been several other vehicles with the same known issue.”

“TSB 19-NA-121. My truck is experiencing the exact issues detailed in the listed TSB. Randomly and quite often my truck feels like I am running over speed bumps. This just started about 3 days ago. The truck has been maintained. Oil is changed on time and there was a 100,000 mile service and I just had a 150,000 service done. Currently there are roughly $148,000 miles on the vehicle. Is there a way to have GM cover the costs of the repairs even though my VIN# was not listed. Also I am experiencing sudden power loss which is also mentioned in other bulletins. Basically it feels like the engine hesitates to accelerate.”

“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 (previously Preliminary Evaluation PE24004).While my vehicle is currently running and has 52,000 miles on the odometer, it falls squarely within the manufacturing window being investigated for premature engine failures due to defective connecting rod bearings and Dynamic Fuel Management (DFM) lifters.My primary concern is the severe safety hazard presented by a sudden, catastrophic engine failure. A sudden seizure or loss of motive power at highway speeds puts myself, my passengers, and other drivers at an immediate risk of a high-speed collision, especially if it occurs without prior warning lights or symptoms.Because GM’s previous engine recalls (such as 24V-418) excluded the 2019 model year despite utilizing the same vulnerable engine family, I am filing this report to urge the NHTSA to expand the recall to include 2019 models. I want my vehicle's VIN documented as part of this vulnerable population so that a proactive, permanent remedy can be mandated before a dangerous highway failure occurs.”

“Loss of motive power due to engine failure 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.  ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.”

“Loss of motive power due to engine failure 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). To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.”

It provides the ability via a single selection within Techline Connect to first identify which modules need updating and then proceed to updating affected modules (with some exceptions). The updating of modules is completed in parallel instead of the technician needing to update one module at a time. This allows a more streamlined approach for dealers and customers.”
