GMC Truck Settlement: $35M for Faulty Fuel Injection Pumps

In a significant development for owners of certain GMC and Chevrolet trucks, General Motors has agreed to a GMC truck settlement worth $35 million. The settlement has been reached in a class action lawsuit against the company stemming from various 2011-2016 truck models produced with allegedly faulty high-pressure fuel injection pumps, otherwise known as the CP4s.
The GMC truck settlement is meant to provide relief to owners who experienced economic damages due to the fragile nature of these CP4 pumps, which were prone to failure and led to costly repairs. In total, the proposed settlement covers 2011-2016 Chevrolet Silverado and GMC Sierra trucks equipped with Duramax diesel 6.6L V8 LML engines.

Eligibility for the GMC Truck Settlement
To be eligible for a payment under the GMC truck settlement, you must own one of the affected vehicles purchased from a GM-authorized dealer in California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas between March 1, 2010, and September 13, 2024. The specific models covered by the settlement include:
- 2011-2016 Chevrolet Silverado trucks with a Duramax diesel 6.6L V8 LML engine
- 2011-2016 GMC Sierra trucks with a Duramax diesel 6.6L V8 LML engine
Owners who are unsure if their vehicle qualifies for the GMC truck settlement can use the provided VIN lookup tool on the litigation website to check their eligibility.

Payout Options for Affected Owners
The GMC truck settlement outlines three different types of payment for affected parties, with payout amounts depending on the number of valid claims received. The options include:
- Out-of-pocket reimbursement: Owners who paid for CP4 repairs not covered under warranty can claim from a $30 million fund, with individual payments ranging from $6,356 to $12,712.
- Financial assistance: Owners who lost their affected trucks without paying for a CP4 repair can draw from a $5,000,000 fund, with payouts between $400 and $800 per person.
- Future repair credit: Owners whose trucks still need a CP4 repair can get 50 percent of the repair cost back if the work is done at an authorized GM dealership within 12 months of settlement approval, or before 200,000 miles, whichever comes later.

Filing a Claim for the GMC Truck Settlement
To receive a cash payment under the GMC truck settlement, affected owners can file a claim online, by email, or by phone. Owners have six months to file, though the deadline could be as early as July 21, 2025, depending on the final court hearing. More information on the settlement's status is available on the litigation website.
Owners who want reimbursement for future repair costs need to file a Reimbursement Request Form. That option only becomes available once the settlement receives final approval, and claims must be filed within 60 days of the repair date. The repair itself has to be done at an authorized General Motors dealer to qualify.

GM Denies Wrongdoing in GMC Truck Settlement
Despite agreeing to the $35 million GMC truck settlement, General Motors denies any wrongdoing. The company chose to settle rather than face the cost, time, and uncertainty of continued litigation, a move it says serves the best interest of both GM and affected vehicle owners.
The settlement is still pending final court approval before the claims process can move forward. Once approved, it should provide meaningful relief to owners who've been financially hit by the defective CP4 fuel injection pumps.

The Importance of the GMC Truck Settlement
The GMC truck settlement is a reminder that automakers can be held accountable for defective parts that create real financial strain for vehicle owners. By agreeing to the settlement, General Motors is taking responsibility for addressing the fallout from the CP4 pump issue, even without admitting fault.
The case also offers a useful example of how and when consumers should take action if they discover a defect in their vehicle. By participating in the GMC truck settlement, affected owners can recoup some of the expenses tied to the defective fuel injection pumps and get their vehicles properly repaired.
As the claims process moves forward after final court approval, eligible owners of the affected 2011-2016 Chevrolet Silverado and GMC Sierra trucks should stay alert and follow the necessary steps to secure their compensation. Cases like this one underscore how important consumer protection remains in the auto industry.
