GM Fuel Pump Settlement 2026 -- File Your Reimbursement Claim by July 5

What happened

Class period: March 1, 2010 through September 13, 2024

• Plaintiffs sued General Motors alleging that 2011-2016 Chevrolet Silverado and GMC Sierra diesel trucks equipped with 6.6L Duramax engines contained a defective high-pressure fuel injection pump known as the CP4
• The CP4 pump is alleged to be unreasonably fragile -- its internal parts rub against each other, generating metal shavings that contaminate the entire high-pressure fuel injection system and can cause complete engine shutdown
• Plaintiffs alleged GM knowingly concealed this defect from truck owners, causing economic damages; this lawsuit does not involve personal injury claims
• GM denied all wrongdoing and contested the claims; the court did not rule on who was right or wrong
• The parties reached a $35 million settlement to resolve the case, which received final court approval on May 6, 2025

Extra details

• The Reimbursement Program covers parts, labor, diagnostic testing, and mechanical damage to the CP4 fuel pump and related components listed in GM Technical Service Bulletin 16-NA-102 -- it does not cover diagnostic fees or repairs to components not specifically on that list
• Repairs must be performed at a GM-authorized dealership to qualify -- GM dealer staff cannot process or answer questions about the reimbursement claim itself; contact the settlement administrator directly
• The future warranty coverage transfers with the truck if you sell it, subject to the same time and mileage limits (12 months from May 6, 2025, or until the truck reaches 200,000 miles, whichever comes first)
• Any settlement funds remaining after all valid claims are paid will be donated to charitable causes that indirectly benefit the class -- none will be returned to GM
• Use the VIN lookup tool at gmfuelpumplitigation.com to verify your truck is a class vehicle before filing
