About This Video

Things have officially escalated with the GM 6.2L L87 situation, and in this video I’m walking you through a brand-new NHTSA document dated March 10th, 2026 tied to Engineering Analysis EA25-007. This isn’t some media recap—this is a formal NHTSA information request letter sent to GM, and I go top-to-bottom explaining what the language actually means in plain English for truck and SUV owners. I also call out why this matters to me personally, because I own a 2021 GMC Sierra AT4 6.2L and my powertrain warranty just ran out. The big headline: NHTSA says they’ve received 225 reports of L87 engine failure in vehicles that were NOT included in the current recall (25V274), and many of those complaints describe sudden loss of motive power. I break down which vehicles NHTSA is looking at (Silverado, Sierra, Tahoe/Suburban, Yukon, Escalade, etc.), why an Engineering Analysis is a serious phase, and what regulators are demanding from GM—warranty data, field reports, internal engineering discussions, supplier component info, manufacturing changes, basically everything. My main takeaway is simple: this letter doesn’t automatically mean an expanded recall is guaranteed, but it confirms the investigation is active, evolving, and now focused on vehicles outside the recall population. GM’s response is due by April 22, 2026, and I’ll be watching NHTSA closely and updating you as soon as anything significant changes.
