In the past 6 years I have owned 4 GMC 6.2L trucks the first was a 2019 no issues great truck. The second unfortunately had a Short life with another vehicle. In 2023 The third a 2021 Denali 6.2L truck at 34k began using oil and blowing blue smoke out the tailpipes. The dealer started an oil consumption test (like you couldn’t see it happening) so finally at 45k they tore down the engine and found worn out valve guides and scored cylinders. They ordered an engine the engine was installed and it failed in 25 miles come to find out it was not oiling on one bank, A second motor was ordered and installed it failed at start up. At this time it had been months that the truck was down. The dealer took a stand and moved me into a 2022 GMC AT4 with 6.2L with the hopes of removing the issue this truck was the internet sales managers truck that he had recently bought and had 15k on. We made the deal, well at 35k this truck begins consuming oil. The dealer once again starts the oil consumption test process. A couple of months ago. The truck now has 42k or so on it and on my last trip from Atlanta to Fort Walton after the dealer just topped it off 2 1/2 weeks prior to the first 2500 interval of the oil consumption test, the truck burned 1 1/2quarts in less than 2k miles and the oil warning light comes on as we arrive in Fort Walton. I would like a resolution to this, I have invested a lot of money into what should be one of the most reliable trucks on the road and all I hear is GM says it’s not met their threshold of a problem and you should expect to have to add oil to a truck with less than 45k on it and it’s not a problem. It’s already been proven with the 2021 that GM has a problem, I as well as the other 100,000 or so individuals with this same engine and GM knows it’s a problem with the quality of the engine build. GM has a quality issue and knows it but they are not addressing it, just making the consumer jump through hoops and not finding a fix in 5 yr's is bad

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).
