The GM 6.2L L87 Engine Defect: What Owners Need to Know

General Motors (GM) has acknowledged a serious manufacturing defect in its popular 6.2L V8 L87 engine. The defect involves the connecting rod and/or crankshaft components, which can fail without warning. This leads to catastrophic engine damage, sudden loss of propulsion, stalling, and in some cases, engine fires or crashes.

The defect has triggered:

• A massive safety recall (NHTSA Campaign #25V274000 / GM #N252494000)
• Multiple class-action lawsuits that have now been consolidated in federal court
• Ongoing NHTSA investigations (including a new probe opened in January 2026 after post-recall failures)

Even after the recall remedy (oil change to heavier 0W-40 viscosity, filter/cap replacement, or full engine swap in some cases), many owners continue to report failures, reduced fuel economy, and higher maintenance costs. If your vehicle has been repaired multiple times, been out of service for 30+ days, or still exhibits the same dangerous issues, it may qualify as a lemon under your state's Lemon Law.

Affected Vehicles (2021–2024 Models with L87 6.2L V8)

The recall and lawsuits primarily cover these GM full-size trucks and SUVs:

• Chevrolet — Silverado 1500, Tahoe, Suburban
• GMC — Sierra 1500, Yukon, Yukon XL
• Cadillac — Escalade, Escalade ESV

Note: While some earlier 2019–2020 models have reported similar issues and are included in certain class-action complaints, the official safety recall applies to vehicles produced between March 2021 and May 2024. Check your VIN with your dealer or on NHTSA.gov to confirm eligibility.  Approximately 597,630 vehicles in the U.S. (and over 721,000 worldwide) are part of the recall.

Common Symptoms of the Defective GM 6.2L Engine

• Sudden loss of power or complete engine shutdown while driving
• Loud knocking, banging, or metallic noises
• Check engine light or low oil pressure warnings
• Transmission hesitation or surging RPMs
• Engine seizure or connecting rod breaching the engine block
• Stalling on highways or in traffic
• In severe cases: engine fire or crash risk

These problems can occur at low mileage (some as low as 1,200 miles) and often strike without prior warning.

Your Legal Rights: Lemon Law + GM Class Action Lawsuit

Lemon Laws (varies by state but generally applies to new or certified pre-owned vehicles) If your GM vehicle has a substantial defect that:

• Substantially impairs its use, safety, or value, and
• GM/dealer cannot repair it after a reasonable number of attempts (typically 3–4 repair attempts for the same issue or 30+ days out of service), …you may be  entitled to:
• A full refund (minus a reasonable usage fee where applicable)

• A replacement vehicle of comparable value
• Cash compensation for diminished value, repair costs, towing, rentals, and attorney fees

The GM recall does not prevent you from pursuing a Lemon Law claim. Many owners who received the recall “fix” still experience recurring failures and successfully lemon their vehicles.

Class Action Lawsuit Update and Concerns Multiple lawsuits alleging GM knowingly sold vehicles with this dangerous defect have been consolidated into a single massive case in the U.S. District Court for the Eastern District of Michigan. The consolidated complaint (389 pages) seeks damages for affected owners.   While the class action may provide some relief, an individual Lemon Law claim often delivers faster and more complete results (full buyback vs. partial settlement).  While the class action may provide some relief, an individual Lemon Law claim resolve your claim quicker and with better compensation.  Why?
