GM Fuel Pump Settlement Payout Date: What You Need to Know in 2026

If you own a 2011–2016 Chevrolet Silverado or GMC Sierra with a 6.6L Duramax diesel engine and are waiting for your GM fuel pump settlement payout, here is the key takeaway: The payout date is not a single fixed date, but depends on which claim type you filed. The settlement website confirms that the Reimbursement Program for future repairs is available until May 6, 2026 (or until your truck reaches 200,000 miles, whichever comes first). For past repair claims, the deadline to submit a claim form was November 6, 2025, which has already passed. The court held a final approval hearing on January 21, 2025, and payments are expected to be distributed after the court's final approval is finalized.

Who Is Eligible for the Settlement?

The settlement, known as Chapman v. General Motors LLC, covers consumers who bought a model year 2011–2016 Chevrolet Silverado or GMC Sierra equipped with a 6.6L Duramax diesel engine and a Bosch CP4 high-pressure fuel pump. You must have purchased the vehicle from a GM-authorized dealer in one of these seven states: California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas. The purchase must have occurred between March 1, 2010, and September 13, 2024.

What Are the Payout Amounts?

The total settlement fund is $35 million. Payout amounts vary based on your situation:

  1. Past repair claims (now closed): If you paid out of pocket for a CP4 fuel pump repair that was not covered by warranty, you could receive between $6,356 and $12,712. The exact amount depends on the number of valid claims filed.

  2. Former owner claims (now closed): If you no longer own your truck and did not pay for a repair, you could receive between $400 and $800.

  3. Future repair reimbursement (still available): If you pay for a CP4 fuel pump repair at a GM-authorized dealership on or after May 6, 2025, you can get 50% of your repair costs reimbursed, up to $5,000. You must submit a reimbursement request form within 60 days of the repair date. This program is available until May 6, 2026, or when your truck reaches 200,000 miles.

Important Deadlines to Remember

The settlement has several deadlines, and some have already passed:

  • December 12, 2024: Deadline to exclude yourself from the settlement or object to it (passed).
  • January 21, 2025: Final approval hearing (completed).
  • November 6, 2025: Deadline to file a claim for past repairs or as a former owner (passed).
  • May 6, 2026: Deadline for the Reimbursement Program for future repairs (still active).

If you missed the past repair claim deadline, you can still benefit from the Reimbursement Program if you have a future repair at a GM dealership. Check your VIN on the official settlement website: www.GMFuelPumpLitigation.com.

What If You Need a Replacement Fuel Pump?

Whether you are covered by the settlement or not, if your fuel pump fails, you need a reliable replacement.
