GM 6.2L V8 L87 Engine Recall: What You Need to Know About Motor Oil

General Motors has issued a recall affecting nearly 600,000 full‑size trucks and SUVs with the 6.2L V8 L87 engine built during 2021–2024. Certain engines may fail unexpectedly due to manufacturing defects in the crankshaft or connecting rod, which could result in total engine failure and risk of crash or injury.¹

Recall Scope and Inspection Protocol

• The recall covers certain Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade/ESV, Chevrolet Tahoe/Suburban, and GMC Yukon/Yukon XL vehicles from model years 2021–2024. 2025 models, as well as 2019 and 2020 units, are not included.²

• Dealers will inspect each engine based on VIN classification. Vehicles that pass inspection typically receive an oil and filter change using 0W‑40 dexosR oil—and a new oil cap to indicate the switch. If the engine fails inspection, GM may install a replacement or extend engine coverage.³

Oil Viscosity Change: Why It Matters

Under the original owner’s manual, these engines were recommended to use 0W‑20 dexos1 Gen 3 oil. However, the recall mandate requires 0W‑40 dexosR oil in non‑replaced engines, due to its thicker viscosity at operating temperature. The goal is to enhance lubrication and reduce bearing stress related to the manufacturing defects.⁴

Owners should be aware that using a thicker oil like 0W‑40 may result in slightly lower fuel economy. At the same time, GM’s Oil May serve as a temporary measure—or “bandaid”—until the engine warranty period expires. Some ongoing class‑action lawsuits argue that the oil change solution may be inadequate and that engine replacements are not always effective or necessary.⁵

What to Do If Your Vehicle Is Recalled

1. Confirm recall eligibility using your VIN through GM Owner Center or the NHTSA website. Recall notices began mailing in June 2025.¹

2. Bring your vehicle to a GM‑authorized dealer to complete the inspection and follow the prescribed remedy.

3. Keep detailed records of all correspondence, inspection results, oil change receipts, and work orders.

4. Stay informed on warranty coverage — GM is providing up to 10‑year/150,000‑mile extended coverage for certain classifications.²

Legal Developments and Consumer Rights

Consumers have filed class‑action lawsuits alleging that GM’s recall remedy is insufficient. Plaintiffs claim that engine replacements may contain the same defective parts and that GM did not adequately inform owners. These filings seek compensation based on safety risks, diminished resale value, and repair expenses.⁶

Bottom Line

If your GM vehicle is equipped with a 6.2L L87 V8 engine built between 2021 and May 2024, it may be at risk. The recall process involves inspection and an oil change remedy for non‑replaced engines. While thicker motor oil may offer added protection, it is not a permanent fix—and your warranty rights may be your best safeguard.
