GM Could Owe You Up to $12,712 If the Fuel Pump in Your Diesel Sierra or Silverado Failed

Previous owners of a 2011-2016 Chevrolet Silverado or GMC Sierra with the 6.6-liter Duramax V8 may also qualify for a payout

General Motors has agreed to pay $35 million to settle with owners following a class action lawsuit that accused the company of installing defective high-pressure fuel pumps in certain Chevrolet and GMC pickup models. The settlement comes after years of allegations that GM knowingly equipped some of its popular heavy-duty trucks with faulty fuel pumps, exposing owners to the risk of sudden engine failure.

The lawsuit targeted 2011-2016 Chevrolet Silverado and GMC Sierra models with 6.6-liter Duramax diesel V8 engines, which were equipped with Bosch ‘CP4’ high-pressure fuel pumps. These pumps were described as “unreasonably fragile and prone to catastrophic failure.”

It’s claimed that these fuel pumps tend to produce metal shavings when internal components grind against each other. Once these metal particles contaminate the fuel injection system, it can result in a complete engine shutdown—an issue that is both hazardous and expensive to repair.

Who Is Eligible?

While GM has denied any wrongdoing, the company chose to settle to avoid the rising costs of prolonged litigation. This settlement is significant for current and former Silverado and Sierra owners. To qualify for a payout, class members must have purchased an affected truck from a GM-authorized dealer in California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas.

Of the $35 million settlement, $30 million will be allocated to current owners who purchased an affected Silverado or Sierra between March 1, 2010, and September 13, 2024, and paid out of pocket for a CP4 fuel pump repair that wasn’t covered by warranty. Depending on the number of claims, individual payments are estimated to range between $6,356 and $12,712, offering significant refunds to those who faced costly repairs.

The remaining $5 million will be distributed to class members who no longer own their diesel trucks or didn’t pay out of pocket for a CP4 repair. These individuals can expect smaller compensation, likely between $400 and $800, though the exact amount will depend on the number of valid claims submitted. Additionally, those who haven’t yet experienced fuel pump failure but encounter it in the future may receive up to 50% reimbursement for repair costs, offering some relief for unlucky owners down the line.

How to File a Claim

If you or someone you know owned or currently owns a 2011-2016 Silverado or Sierra with the 6.6-liter Duramax diesel engine, it’s worth checking the GM Fuel Pump Litigation website to see if you’re eligible for this settlement. After all, how often do big companies hand out money?
