— A settlement in the General Motors Duramax diesel CP4 fuel pump litigation has been preliminarily approved after vehicle owners alleged that the Bosch CP4 fuel pumps were defective.
The fuel pump lawsuit involves 2011 through 2016 Chevrolet Silverado and 2011 through 2016 GMC Sierra trucks equipped with the Duramax diesel 6.6L V8 engine.
The Duramax truck fuel pump lawsuit claims these trucks are dangerous because the fuel pumps can shut off the engine while the truck is moving.
“The plaintiffs allege that GM then charged consumers $10,000 for the repairs, even though the company allegedly knew ‘that any such repairs would be futile as they would not actually resolve the problem as long as the vehicle was running on U.S. diesel.'”
Bosch CP4 fuel pumps allegedly failed when used with U.S. diesel fuel because the pumps were too fragile to handle U.S. diesel fuel. The plaintiffs claimed that the pumps produced metal shavings that damaged the fuel injection system and the Duramax engine.
The original consolidated fuel pump class action lawsuit was filed against owners nationwide and involved other vehicle models.
But as with many automotive class-action lawsuits, the trucks appear to be defective, but only if they were purchased in seven states.
To qualify for the settlement, owners must have purchased a 2011 to 2016 Chevrolet Silverado or GMC Sierra Duramax diesel 6.6L V8 truck from a GM dealer after March 1, 2010, and only in the following states: California, Florida, Illinois, Iowa, New York, Pennsylvania or Texas.
GM Diesel Fuel Pump Class Action Lawsuit (Chapman v. General Motors) is consolidated from the following class actions:
GM has denied all allegations and that the trucks are defective.
GM Diesel Fuel Pump Litigation Settlement — Compensation Fund
Vehicle owners who have diesel fuel pump repairs carried out at their own expense may be reimbursed if the repair work was carried out in accordance with the Bosch CP4 fuel pump’s alleged defect (causing metal shavings).
This meant that the problem must have been caused by metal fuel pump parts rubbing against each other, creating metal shavings that contaminated the Duramax diesel fuel system and caused catastrophic engine failure.
The amount of compensation depends on the number of customers who make claims.
Former diesel truck owners may also be eligible for compensation for allegedly overpaying for their vehicles.
GM Diesel Fuel Pump Litigation Settlement — Future Warranties
All current customers who still own their trucks will receive future warranty coverage for repairs on the CP4 fuel pump and related components at GM dealers.
However, due to limited warranty coverage going forward, GM diesel truck owners will have to pay 50 percent of the repair costs.
This fuel pump extended warranty is for up to 12 months from the date of final approval of the class action settlement or 200,000 miles from the date of original sale, whichever comes first.
The GM diesel fuel pump settlement final fairness hearing is scheduled for January 21, 2025.
The plaintiffs who filed the 574-page class-action lawsuit will each receive $5,000: Mark Chapman, Kyle McDuffie, Bryan Joyce, Stacy Wade Sizelove, Kevin Allen Lawson, Holly Reasor, Homero Medina, Jacqueline Bargstedt, Calvin Smith, Nathan Howton and Trisha Alliss.
Under the settlement, attorneys representing the plaintiffs will receive $15 million.
The GM Truck Diesel Fuel Pump Litigation has been filed in the U.S. District Court for the Eastern District of Michigan (Southern Division): Chapman et al. v. General Motors LLC.
The plaintiffs are represented by Hagens Berman Sobol Shapiro LLP, Hilliard Martinez Gonzalez LLP and The Miller Law Firm PC
