GM fuel pump settlement overview:ย 

  • Who: General Motors has reached a $50 million settlement with drivers of certain diesel trucks and vans.
  • Why: The plaintiffs said their vehicles were fitted with CP4 fuel pumps that came with โ€œcatastrophicโ€ complications.
  • Where: The GM fuel pump settlement was filed in a Michigan federal court.ย 

General Motors has reached a preliminary $50 million settlement agreement with drivers who accuse it of selling vehicles with CP4 fuel pumps that are โ€œticking time bombs.โ€

The plaintiffs filed a motion indicating their support for the proposed settlement on June 7. The settlement would end class action claims that GM knowingly sold diesel trucks equipped with CP4 high-pressure fuel injection pumps supplied by Bosch.ย 

Although these fuel injection pumps reportedly saved money for GM, the pumps allegedly resulted in โ€œcatastrophicโ€ complications.

The plaintiffs alleges the CP4 fuel pumps are not compatible with American diesel fuel and reportedly โ€œrun the pump nearly dry so that it destroys itself, and โ€” ultimately โ€” destroys the fuel injection system and engine altogether.โ€

Judge: Proposed settlement appears fair

On July 11, a Michigan federal judge indicated he would give his initial approval to the settlement, Law360 reports.

U.S. District Judge Terrence G. Berg said the class settlement with GM seemed to give a fair amount of payment to drivers who say they either overpaid for their allegedly defective vehicles or had to pay out of pocket for repairs.ย 

โ€œThe pump secretly deposits metal shavings and debris throughout the fuel injection system and the engine until it suddenly and catastrophically fails without warning,โ€ the CP4 fuel pump lawsuit argues.

The settlement covers customers who purchased certain-year GMC and Chevrolet diesel trucks that were fitted with 6.6L V8 Duramax LML engines or LGH engines equipped with a CP4 fuel injection pump from GM-authorized dealerships in California, Florida, Illinois, Iowa, New York, Pennsylvania and Texas.ย 

Under the settlement, GM would pay $50 million to compensate truck owners who paid out of pocket for repairs to their engines due to the alleged defect and former owners who allegedly overpaid for their vehicles. Drivers who had to pay for repairs could see between $6,300 and $12,700, depending on the number of claimants, Law360 reports.ย 

GM also agreed to provide a 12-month future limited warranty that covers 50% of the cost of repair or replacement if a fuel pump on a class memberโ€™s car fails during the warranty period, which begins after final approval of the settlement.

    There is no settlement administrator website created for this? Anyone know details of when that will be created? Or do we contact GM directly?

    1. Ken Kozola says:

      I have a โ€™16 Chev High Country with the 6.6 diesel and CP 4 pump. It is a low mileage truck and I havenโ€™t had a problem yet. Hearing about this defect has me very concerned. What can I do to protect myself if my truck should develope a problem in the future? Is there a way for GM to replace the CP4 pump with a more reliable model prior to failure and significant expense?

        Get an airdog lift pump and use standyne additive for lube.
