GM 6.2L Engine Failures: What To Do If Your Truck Isn’t in the Recall (L87 Investigation Update)

GM 6.2L L87 Engine Failure & Investigation Update — What Owners Should Do (Not Legal Advice) The NHTSA investigation into GM’s 6.2L L87 V8 engine (Investigation EA25007) is still open, and every week I receive messages from Silverado, Sierra, Yukon, Tahoe, Suburban, and Escalade owners who experienced engine failure outside the official recall window — and don’t know what to do next. In this video, I break down: • What’s happening with the L87 investigation • Why some 2019–2021 owners and early 2021 builds are not in the recall • What steps you can take if you’ve had an engine failure • How to file proper documentation with NHTSA & GM • How to advocate for yourself respectfully and effectively This is not anti-GM. I own a 2021 GMC Sierra AT4 and a 2022 Cadillac Escalade. I love these vehicles and share this information so owners can stay informed and safe — and so GM has clear, documented data to help resolve legitimate issues. 📌 If Your 6.2L Engine Failed and You Were Not in the Recall Here are the recommended steps discussed in the video: 1️⃣ File a Safety Complaint with NHTSA (U.S. owners) (These reports help NHTSA track patterns affecting the open investigation.) 👉 https://www.nhtsa.gov/report-a-safety-problem 2️⃣ Contact GM Customer Assistance – United States ➡️ GM “My GM Experience” Support Page https://experience.gm.com/ ➡️ Chevrolet Customer Assistance https://www.chevrolet.com/contact-us ➡️ GMC Customer Assistance https://www.gmc.com/contact-us ➡️ Cadillac Customer Assistance https://www.cadillac.com/contact-us 3️⃣ GM Canada – Contact Information (For Canadian Owners) ➡️ GM Canada Customer Care https://www.gm.ca/en/contact-us.html ➡️ Chevrolet Canada Support https://www.chevrolet.ca/en/support ➡️ GMC Canada Support https://www.gmc.ca/en/support ➡️ Cadillac Canada Support https://www.cadillac.ca/en/support 4️⃣ Include this information when you contact NHTSA or GM: • Year, model, mileage • Full description of symptoms before the failure • Dealer diagnosis (if available) • Photos/videos if applicable • Any out-of-pocket repair estimates • Whether your VIN was included in recall 25V-274 The more complete your documentation, the easier it is for regulators and GM to understand and track the issue. 📘 Official Documents & Investigation Here are the primary publicly available sources referenced in my ongoing coverage: • NHTSA Engineering Analysis EA25007 (Open) PDF: https://static.nhtsa.gov/odi/inv/2025/INOA-EA25007-23191.pdf • Original GM Recall 25V-274 (for certain L87 6.2L engines built March 2021 – May 2024) https://www.nhtsa.gov/recalls • NHTSA Vehicle Lookup (to check your VIN for recalls) https://www.nhtsa.gov/recalls Full Video from the Corvette Driving School: We Drove Our NEW Corvette C8 to Track School… Should We Have?! https://youtu.be/hyya4V71jOE 🙌 About This Channel I’m Don from Donslife — I create home & automotive DIY content, tech reviews, and honest coverage of issues that affect me and my audience.
