Last updated: July 12, 2026
General Motors agreed to pay $50 million to settle a class action alleging that the Bosch CP4 high-pressure fuel pump in certain 2011–2016 Duramax diesel trucks was prone to failure. The claim deadline has passed — it closed on November 6, 2025 — so new claims are no longer accepted. Owners who paid out of pocket for a CP4 repair can receive between $6,356 and $12,712, and those who didn't pay or no longer own the truck receive $400 to $800, with checks being distributed following the court's May 6, 2025 final approval.
The settlement, Chapman v. General Motors LLC (Case No. 2:19-cv-12333-TGB-DRG, E.D. Mich.), covers people who bought a 2011–2016 Duramax diesel Chevrolet Silverado or GMC Sierra from a GM-authorized dealer in California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas. Of the $50 million fund, $30 million is set aside for owners who paid for a CP4 fuel pump repair. The deal also added a renewed limited warranty on the CP4 pump that runs through May 7, 2026 or 200,000 miles, whichever comes first.
