Learn more about how you can join the GM class action lawsuit.

Why Are There GM Class Action Lawsuits?
General Motors faces multiple class action lawsuits due to widespread vehicle defects affecting safety and reliability. Current GM lawsuits include the $150 million oil consumption settlement, 6.2L V8 L87 engine failures, and transmission defects in 8L90 and 8L45 systems. These recurring issues affect thousands of GM vehicle owners nationwide.
GM Class Action Lawsuit Eligibility Requirements
Check Your Vehicle Model and Year
Not all GM vehicles qualify for class action lawsuits. Current active lawsuits include:
- GM Oil Consumption Lawsuit affecting 2010-2019 Chevrolet
- GMC vehicles with excessive oil burning
- GM L87 Engine Lawsuit covering 2019-2024 vehicles
- 6.2L V8 engines experiencing premature failures
- GM Transmission Lawsuit for vehicles with 8L90 or 8L45 eight-speed automatic transmissions
- GM Fuel Pump Settlement for 2011-2016 Chevrolet Silverado
- GMC Sierra diesel trucks
Document Qualifying Defects
Your GM vehicle must exhibit serious, recurring problems to qualify for class action participation.
These typically include engine stalling or complete failure, excessive oil consumption requiring frequent top-offs, transmission issues like shuddering or harsh shifting, brake malfunctions that affect safety, and fuel system failures. The key is demonstrating that these problems persist despite multiple repair attempts.
Maintain Repair Documentation
Successful GM class action claims require comprehensive documentation of your vehicle’s issues and repair history. This includes all repair invoices and service records, warranty claims filed with GM, communication records with dealerships or GM customer service, and photos or videos of defects when possible. Thorough documentation strengthens your case and proves you’ve given GM opportunities to resolve the problem.

Step-by-Step Guide on How to Join GM Class Action Lawsuit
1. Consult a Lemon Law Attorney
Contact a qualified lemon law attorney specializing in GM defect cases. California residents should seek attorneys familiar with the state’s strong lemon law protections. Most attorneys offer free consultations and work on contingency fees.
2. Verify Your Eligibility
Your attorney will review your vehicle identification number (VIN) to confirm affected models, examine your purchase or lease documentation, analyze your repair history and warranty claims, and determine whether your case fits class action requirements. This thorough evaluation ensures you meet all necessary criteria before proceeding.
3. Gather Required Documentation
You’ll need to compile essential documents including proof of ownership such as your title, registration, or lease agreement. Complete repair records from every service visit related to the defect are crucial, along with warranty documentation for any claims filed with GM. Communication logs including emails, letters, or phone records with GM or dealers also strengthen your case.
4. File Your Class Action Claim
Once eligibility is confirmed, your attorney will submit your claim to join the appropriate GM class action, ensure all required documentation is properly filed, and represent your interests throughout the legal process. This formal step officially makes you part of the collective lawsuit against GM.
5. Stay Updated on Case Progress
Class action lawsuits can take months or years to resolve. Your attorney will provide regular updates on settlement negotiations, court hearings and deadlines, and final approval of any agreements. Staying informed helps you understand the timeline and any actions you may need to take.

Weighing the Pros and Cons: Is Joining a Class Action Right for You?
It’s worth noting that class actions aren’t the only way to pursue compensation. If you’re in California, you could explore filing an individual lemon law claim, which allows you to work directly with a lemon law attorney on your own claim. This can sometimes lead to a quicker resolution than joining a class action.
| BENEFITS OF JOINING A CLASS ACTION | CONSIDERATION BEFORE JOINING |

| Possible access to collective compensation or repairs | Settlement amounts vary, and compensation isn’t guaranteed |
