Common questions

How much does the GM Fuel Pump Settlement pay?
Estimated payout: Cash payment for CP4 fuel pump repairs paid out of pocket; cash payment for former owners who no longer own their trucks; 50% reimbursement for future CP4 fuel pump repairs performed on or after May 6, 2025. Actual amounts depend on how many valid claims are filed — most settlements divide a fixed fund pro rata, so a higher claim rate means a smaller individual check. An "up to" figure is a cap, not a guarantee.
What is the claim deadline for the GM Fuel Pump Settlement?
This settlement is closed to new claims — the deadline was November 6, 2025. Once a claim deadline passes you generally forfeit your share, even if you qualified.
Do I need proof of purchase for the GM Fuel Pump Settlement?
Yes. This settlement asks for documentation supporting your claim — a receipt, an account record, or the notice you were sent. Check the official settlement website for exactly which documents are accepted.
Is the GM Fuel Pump Settlement notice real, or a scam?
JND Legal Administration is the settlement administrator for this case. Claims are filed at gmfuelpumplitigation.com. Filing a class action claim is always free — no legitimate settlement charges you to claim, and no administrator will ask for payment, a gift card, or your full Social Security number by email or text. If a notice asks for any of those, it is not from the administrator. When in doubt, ignore the link you were sent and go to the official settlement website directly.
When will payments from the GM Fuel Pump Settlement be sent?
Class action payouts typically take 12 to 24 months after the claim deadline, and longer if the settlement is appealed. Payments cannot be issued until the court grants final approval and any appeals are resolved.
