While driving on the road the vehicle started sputtering and stalled! We pulled to the side of the road and tried to start the car but it rolled and would not start. We called a a mechanic who had it towed and found out that the fuel pump and the fuel control board had failed. Both have been replaced and the truck seems to be working again. Heard several other persons had this issue with their GCM Sierra Elevation so we wanted to report since there is currently no recall. Luckily the traffic was not going that fast or we could have had an accident and been seriously injured.

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.

On November 16, while driving on the highway, my GMC vehicle suddenly lost engine power without warning. I was forced to stop in traffic, creating a dangerous situation and putting my life at risk. The vehicle required towing and has remained at the dealership since that date. The dealership determined that the engine requires replacement. Repairs have been significantly delayed, including an incorrectly ordered replacement engine, and the vehicle remains out of service more than two months later. This defect caused a sudden loss of power while driving and presents a serious safety concern.After the incident, I contacted the dealership immediately. Diagnostic appointments were scheduled and then canceled by the dealership twice, which delayed inspection and repair. I was only able to leave the vehicle at the dealership on December 12 due to these delays.

My truck went into "limp" mode and had very little power. It was towed to the dealership where they diagnosed the issue as a bad solenoid causing the engine misfires. The solenoid was replaced, but the issue was not fixed. Now the dealership is stating the engine has bent lifters and the repairs will not be covered under the ongoing massive engine recall. The vehicle had the pico test on 9/17 and it "passed", but less than 3k miles later and the engine failed. This is a clear safety issue and well known by NHTSA and GM. Now I'm negotiating with the dealership to cover repairs and my truck has been gone nearly a month.

My truck is under the national recall from GMC for the 6.2L engine problems. I even received the recall notice from GMC stating this. This truck has been in and out of the shop for engine problems things I took delivery of it in 2022. The latest was in April of 2025 and while it was in the repair service at the dealership, the national recall came out. During that time the dealership tried to tell me the problem was with my exhaust system so I was not covered under the recall. I knew they were not being truthful so I refused to take possession of the truck as I new it had all the symptoms that GMC was describing in my recall notice. My truck sat at the dealership for almost 5 months and last week they force me to take possession of my truck my taking back my "loaner vehicle". They stated "my truck passed the required inspection", which I knew they were being dishonest, but was forced to take the truck back anyway. Three days after taking possession I was on the interstate doing 60 mph and the engine totally seized up and almost caused an accident from the vehicles behind me running into me because of the sudden decrease in speed. I was able to safely pull over and had to get towed back to the dealership. This incident is beyond just a engine recall now because they new my truck was not safe to drive and forced me to take back my truck. Im just thankful I was driving and not my wife, or having my two grandchildren in the truck with me. To make mtters worse in this scenerio, this truck is actually my replacement truck because my 2021 truck had to be taken back per the Lemon Law in 2022, so this will now be truck #2 being Lemon Law and my original truck loan isnt even paid off. I have all of the various engine repair paperwork on this truck dating back to 2022.

My daughter and I drove to town to run some errands, we live twenty-three minutes away and take the freeway. Speed limit on that specific section of the freeway (I80) is 80mph. As I was taking the on-ramp to enter traffic, My GMC started shifted very hard and losing power. The vehicle was sputtering and making strange sounds. I was unable to exceed 60mph due to excessive vibrations/shaking the vehicle. Steering was starting to be difficult at the same time I noticed Oil Pressure Gauge slowly dropping on instrument panel below 25psi. I had to pull over immediately. oil pressure remained lower than normal, verified Oil was filled to manufactures specifications (changed June 30, 2025). Returned the vehicle to my place of residence as safe and slow as I possibly could and parked it as it is a major safety concern.

Unloaded my Denali at huge loss with 30,000 miles because gm wouldn’t fix recall after many times in shop, broke down on freeway, and need to travel to Canada on business. Canada won’t allow vehicles with open safety recalls to enter country even though im pretty sure engine was MADE in Canada. Gm corporate office told me there’s nothing they can do. While in shop for 4 days of testing i watched vehicle on app, never started, moved, just put out back for 4 days then told absolutely nothing. Just wanted fair trade in for diesel. Truck looked identical to brand new on lot, 10/10 except engine recall. Gm promised to reimburse rental fees when broke down a week or so, submitted documents to Gm, nothing recieved. Bought ram instead for obvious reasons. Is there a lemon law, class action, agency etc that can help compensate for losses? The public should be warned!

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).
