Chevy Silverado Fuel Pump Failure Lawsuit: Are You Eligible for a Payout?

Here’s how owners of 2011-2016 Chevy Silverado and GMC Sierra diesels can check and see if they’re part of a class action settlement. 

As many Chevy Silverado (and GMC Sierra) HD owners are already well aware, problematic Bosch CP4 fuel pumps made their way into a variety of 6.6-liter Duramax diesel-powered trucks from 2011-2016, which were prone to failure. In fact, this problem was so widespread that a group of owners later filed a class action lawsuit against General Motors – Chapman, et al. v. General Motors LLC – which the automaker opted to settle just this past October. Now, owners of impacted Chevy Silverado and GMC Sierra models can check and see if they’re eligible for a portion of that payout.

GM will pay out $35 million following this decision, but those funds will only be disbursed to a select group of owners. For starters, owners must have purchased their trucks from a GM-authorized dealer in the states of California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas, and need to have done so between March 1, 2020, and September 13, 2024. Folks that meet these requirements will then want to head over here and enter their vehicle’s VIN to see if it qualifies for part of the settlement payout.

On top of these stipulations, impacted Chevy Silverado and Sierra owners with faulty CP4 pumps must still own their vehicles – former owners can still get some money back, though it’s quite a bit less. Those that previously owned one of these diesel models and paid for out-of-warranty repairs can receive somewhere between $400-$800, but current owners that did the same can get anywhere between $6,356 and $12,712.

This is likely to come as a bit of good news for those that have experienced major issues with their CP4 pump, which stem from parts rubbing against each other and generating metal shavings, which can contaminate the entire high-pressure fuel injection system, in some cases leading to engine shutdown. However, in spite of the settlement, GM still denies that the CP4 pumps in question are defective, and denies any wrongdoing in this case.
