Is Your GM 6.2L V8 Engine Failing? Know Your Legal Options

BY PREMIER LEGAL CENTER, APC February 3, 2025

General Motors (GM) is struggling to keep up with the demand for replacements of its 6.2L V8 engines. This powerful engine, used in several popular GM vehicles, has been plagued by performance and reliability issues. Many customers have reported excessive oil consumption, engine knocking, power loss, and recurring check engine lights, leaving them frustrated and searching for solutions.

If you own a GM vehicle with a faulty 6.2L V8 engine, you may be entitled to relief under California Lemon Law. When a manufacturer fails to repair a vehicle’s persistent defects under warranty, the law protects consumers by offering options such as a replacement vehicle, refund, or cash compensation. Understanding your rights is essential in ensuring you receive fair treatment and compensation.

Understanding the 6.2L V8 Engine Issues

The 6.2L V8 engine, featured in high-performance GM trucks and SUVs like the Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade, is known for its power and capability. However, many owners have reported significant problems, including:

  • Excessive Oil Consumption – Some drivers have reported that their 6.2L V8 engines burn through oil at an alarming rate, leading to frequent refills and potential engine damage.
  • Engine Knocking and Ticking Sounds – Unusual noises from the engine, especially knocking or ticking, can indicate internal mechanical failures.
  • Loss of Power and Stalling – Many GM owners have complained about their vehicles suddenly losing power or even stalling, posing a serious safety risk.
  • Check Engine Lights and Misfires – Recurring check engine lights and cylinder misfires have left many drivers frustrated with ongoing repairs.
  • Transmission and Drivability Issues – Some drivers experience rough shifting and hesitation, which may be related to the engine’s malfunction.

GM’s Response to the 6.2L V8 Engine Failures

Due to widespread complaints, GM has attempted to address these issues with Technical Service Bulletins (TSBs), software updates, and warranty-covered repairs. However, many customers find that these fixes do not permanently resolve the problems. Some dealerships are facing backorders on replacement engines, leaving owners without a functioning vehicle for months.

Data According To the Automotive Industry

  • Over 60,000 GM vehicles have been affected by 6.2L V8 engine failures.
  • Some owners have waited over six months for a replacement engine due to supply shortages.
  • Lawsuits and customer complaints against GM have increased by 30% in the last two years.

What Can You Do If Your GM 6.2L V8 Engine Fails?

If you are experiencing engine problems and repeated repairs haven’t solved the issue, you may qualify for a vehicle buyback or compensation under California’s Lemon Law. Here’s what you need to do:

Document Everything – Keep records of all repair attempts, dealership visits, and communications with GM. Service invoices and repair orders are crucial.

Know Your Rights – California’s Lemon Law protects consumers who have purchased or leased defective vehicles. If your car has had multiple repairs for the same issue under warranty, you may be eligible for a refund or replacement.
