What happened

General Motors sold 2011-2014 Chevrolet and GMC pickup trucks and SUVs with LC9 5.3-liter V8 engines that allegedly contain a defective piston assembly. The defect causes excessive engine wear, oil consumption, spark plug fouling, rough idling, check engine lights, and potential engine damage. GM denies any wrongdoing or that the vehicles are defective.

Common questions

How much does the GM Engine Litigation Settlement pay?
Estimated payout: From $2,149. The total settlement fund is $150M. 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.
Do I need proof of purchase for the GM Engine Litigation 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 Engine Litigation Settlement notice real, or a scam?
Postlethwaite & Netterville is the settlement administrator for this case. Claims are filed at gmenginelitigation.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 Engine Litigation Settlement be sent?
Class action payouts typically take 12 to 24 months after the claim deadline, and longer if the settlement is appealed. The final approval hearing for this case is set for October 6, 2025; no payments can be issued before a settlement receives final approval.
