According to a [Reuters report](), the NHTSA Office of Defects Investigation determined the scope and severity of the problem was high enough to take a closer look. Federal Investigators believe a bearing failure could result in engine seizure or breading of the engine block by the connecting rod. This failure would lead to a loss of power. NHTSA states they have received 39 complaints and several early warning field reports from vehicle owners. These owners also said the loss of power was sudden and they had no warning signs before the engine failed. There have been no crashes or fires reported. GM says it will work with NHTSA during this probe. ## Structured page information ~~~json [ { "@context": "https://schema.org", "@graph": [ { "@type": "Article", "@id": "https://pickuptrucktalk.com/2025/01/nhtsa-begins-gm-6-2l-v8-engine-failure-probe/#article", "isPartOf": { "@id": "https://pickuptrucktalk.com/2025/01/nhtsa-begins-gm-6-2l-v8-engine-failure-probe/" }, "author": { "name": "Tim Esterdahl", "@id": "https://pickuptrucktalk.com/#/schema/person/82b06f99329f69a069a5ab6caed18593" }, "headline": "NHTSA begins GM 6.2L V-8 engine failure probe – 870k trucks", "datePublished": "2025-01-17T15:31:12+00:00", "dateModified": "2025-07-23T15:09:41+00:00", "mainEntityOfPage": { "@id": "https://pickuptrucktalk.com/2025/01/nhtsa-begins-gm-6-2l-v8-engine-failure-probe/" }, "wordCount": 176, "commentCount": 0, "publisher": { "@id": "https://pickuptrucktalk.com/#organization" }, "image": { "@id": "https://pickuptrucktalk.com/2025/01/nhtsa-begins-gm-6-2l-v8-engine-failure-probe/#primaryimage" }, "thumbnailUrl": "https://pickuptrucktalk.com/wp-content/uploads/2025/01/2024-gmc-sierra-denali-ultimate-050-copy.webp", "keywords": [ "cadillac escalade", "chevy silverado", "Chevy Suburban", "Chevy Tahoe", "gmc sierra", "gmc yukon" ], "articleSection": [ "Recalls" ], "inLanguage": "en-US", "potentialAction": [ { "@type": "CommentAction", "name": "Comment", "target": [ "https://pickuptrucktalk.com/2025/01/nhtsa-begins-gm-6-2l-v8-engine-failure-probe/#respond" ] } ] }, { "@type": "WebPage", "@id": "https://pickuptrucktalk.com/2025/01/nhtsa-begins-gm-6-2l-v8-engine-failure-probe/", "url": "https://pickuptrucktalk.com/2025/01/nhtsa-begins-gm-6-2l-v8-engine-failure-probe/", "name": "NHTSA begins GM 6.2L V-8 engine failures probe -
