The Court in charge of this case authorized the Notice to inform you about a class action settlement in a lawsuit known as Chapman, et al. v. General Motors LLC, Case No. 2:19-cv-12333, currently before Judge Terrence G. Berg in the United States District Court for the Eastern District of Michigan. You received a Notice because General Motors LLC’s (“GM”) records indicate you may be a current or past purchaser of a Class Truck. 

Plaintiffs sued GM alleging that the Class Trucks had a defective high-pressure fuel injection pump known as the CP4 pump. Plaintiffs allege that the CP4 pump is unreasonably fragile and prone to catastrophic failure. Plaintiffs allege the failure occurs when the CP4 pump parts rub against each other and generate metal shavings which contaminate the entire high-pressure fuel injection system, sometimes leading to engine shutdown. 

Plaintiffs claim that GM knowingly concealed this defect and filed a class action lawsuit based on this defect. Plaintiffs further claim that they and other owners of the Class Trucks have suffered economic damages because of the alleged defect.  This lawsuit does not involve any claims for personal injuries. 

GM denies any wrongdoing and denies that the Class Trucks’ fuel pumps are defective. GM asserted a number of defenses to Plaintiffs’ claims. The Court did not decide who is right or wrong. Instead, the Parties agreed to the Settlement to avoid the costs, risk, and delays associated with further litigation.

The Court did not decide in favor of any Plaintiff or GM on the legal claims being resolved here.  Instead, both sides agreed to a settlement, which avoids the risk and cost of a trial but still provides relief to the people affected.  The Class Representatives and their attorneys think that the Settlement is in the best interests of Class Members and that it is fair, adequate, and reasonable.

You are a Settlement Class Member if you purchased a Class Truck from a GM-authorized dealer in California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas from March 1, 2010 through September 13, 2024. Class Trucks include model year 2011-2016 Chevrolet Silverado or GMC Sierra diesel trucks equipped with 6.6L Duramax engines and Bosch “CP4” high-pressure diesel fuel pumps. 

To check whether you have a Class Truck, you may enter your VIN using the VIN lookup tool.

The Settlement will provide cash payments and other valuable benefits to Class Members. These benefits include:

•    $30 million to pay Class Members who paid out of pocket for a CP4 repair that was not covered by warranty (the “Repair Fund”). The cash you may get depends on how many valid claims are received and could range from $6,356 to $12,712 (see FAQ 9 below).    

•    $5 million to pay Class Members who no longer own their trucks and did not pay out of pocket for a CP4 repair (the “Former Owner Fund”).  Again, the cash you may get depends on how many other claims are received and could range from $400 to $800 (see FAQ 9 below).

•    Cash back for future repairs.  A Partial Repair Reimbursement Program (the “Reimbursement Program”) provides future warranty coverage by reimbursing 50% of costs paid for a CP4 repair. The repair must be performed at a GM-authorized dealership on or after May 6, 2025. The Reimbursement Program will end May 6, 2026 or until the truck reaches 200,000 miles (whichever occurs first). The 12-month future warranty period began May 6, 2025. So if you still own the truck and haven’t had a CP4 repair, please keep the notice so you have it handy in case you need to repair the truck in the future.  Payments might be approximately $5,000 based on average repair cost. Please check this website frequently for additional updates.

For more information: See FAQ 9 for estimated payment amounts. See FAQ 7 to learn more about how to claim a cash payment. See FAQ 12 to learn more about how to request cash back for future repairs. 

Some of you may be paid directly if our records identify you as a Class Member who paid out of pocket for a CP4 repair. But everyone should submit a claim form to make sure that we identify you as a Class Member.    

If you no longer owned a Class Truck on May 6, 2025, and you did not pay for a CP4 repair, you must file a claim to receive a payment. Former owners who do not file a timely and valid claim will not receive any payment from the Settlement.

See FAQ 7 for information on how to submit a claim for a cash payment. See FAQ 9 for information on how much money you might receive.   

To get a cash payment, file a claim online.  You can also download a copy of the Claim Form from the Important Documents page if you cannot complete the form online. You can also request a copy of the Claim Form be mailed or emailed to you by calling or emailing the Settlement Administrator at info@GMFuelPumpLitigation.com or 1-866-848-0815.  You should keep a copy of the completed Claim Form for your own records. Mail or email the Claim Form with the required documentation, described below in FAQ 8, to the Settlement Administrator at: 

GM Fuel Pump Settlement

The deadline to file Claim Forms and supporting documents is November 6, 2025. Check this website regularly for updates. If you do not submit or mail the Claim Form and supporting documents by the required deadline, you will not get a payment unless we are able to pay you directly. Submitting a Claim Form late or without documentation will be the same as doing nothing. 

All claims require supporting documentation, including proof of purchase and proof of repair.  If you no longer own the truck and did not pay out of pocket for a CP4 repair before May 6, 2025, you do not need to submit proof of repair, but you are required to submit proof of sale.  More details are provided below.  

Proof of Purchase: You must submit proof that you purchased your truck from a GM-authorized dealer in California, Florida, Illinois, Iowa, New York, Pennsylvania, or Texas from March 1, 2010 through September 13, 2024, such as a purchase agreement or financing documentation showing your name as well as the name and address of the GM-authorized dealer where you purchased your truck.

Former Owner Proof of Sale: If you sold the truck before May 6, 2025 and you did not pay out of pocket for a CP4 repair while you owned the truck, you must submit proof showing the date you sold your truck.  It should include the date, your name, the Vehicle Identification Number (VIN), and the buyer’s name. 

Proof of Repair: If you paid out of pocket for a CP4 repair before May 6, 2025, you must submit proof of the repair that includes your name, the Vehicle Identification Number (VIN), and clearly identifies the covered parts that were repaired or replaced.  This could take the form of a repair order, invoice, or other documents from the shop that completed the repair.  If you no longer have your CP4 repair records, you must send both of the following: (a) proof of payment for the CP4 repair, such as a copy of a banking or credit card statement that clearly identifies your CP4 repair costs; and (b) a completed Declaration Form.  The Declaration Form is included with the Claim Form.

Different payments are available depending on whether you paid for a CP4 repair before May 6, 2025 and whether you still own the truck.  

Repair Fund: The Repair Fund will be distributed to all of the people that we can pay directly and to people who submit valid and timely claims. The payment amount will be based on the number of people we pay directly, plus the number of people who submit valid claims. Payment amounts for each CP4 repair will be the same for people who are paid directly and people who submit valid claims. Payment estimates for each CP4 repair are provided below.  

•    If 25% of the Class Members who paid for CP4 repairs submit valid claims or are paid directly, payments are estimated to be approximately $12,712.  
•    If 50% of the Class Members who paid for CP4 repairs submit valid claims or are paid directly, payments are estimated to be approximately $6,356.  

Former Owner Fund: The Former Owner Fund will be distributed evenly among former owners who did not pay for a CP4 repair and who submit valid and timely claims.  Payment estimates are provided below. 

•    If 5% of former owners submit valid claims, payments are estimated to be approximately $800.
•    If 7% of former owners submit valid claims, payments are estimated to be approximately $571.43.
•    If 10% of former owners submit valid claims, payments are estimated to be approximately $400.

When you submit your claim, you can choose whether to receive a paper check in the mail or an electronic payment by virtual debit card, Venmo, or PayPal. 
 

Payments will be sent after the Settlement’s “Effective Date” and after the Settlement Administrator has validated the claims. The “Effective Date” will depend on when the Court enters its order finally approving the Settlement and its Judgment, and whether there is an appeal of the Judgment. 

The Final Approval Hearing was rescheduled for April 25, 2025 at 3:00 PM ET.

Please check this website for updates about the timing of settlement payments.

The Settlement will provide cash-back reimbursement of 50% of all costs paid by Class Members or future Class Truck owners for CP4 repairs or replacements performed at GM-authorized dealerships for the following time period: 12 months from May 6, 2025 or until the Class Truck reaches 200,000 miles, whichever occurs first. Covered repairs and replacements include the costs associated with replacement parts, labor, diagnostic testing, and mechanical damage to the CP4 fuel pump and the related components listed in GM Technical Service Bulletin 16-NA-102, available on the Important Documents page. The Reimbursement Program does not cover diagnostic fees or repairs for components that are not specifically included in this list. 

The future repairs described above must be performed by a GM-authorized dealer or they will not be eligible for cash-back reimbursement. This part of the Settlement does not revoke or alter any existing warranties that apply to the Class Trucks. All existing warranty coverage for the Class Trucks is still in effect. Additional terms apply.

For further information about the Future Warranty Coverage and Repair Reimbursement Program, please review the Settlement Agreement, which is available on the Important Documents page.

To qualify for the Reimbursement Program and receive cash back for future repairs, you must first obtain and pay for a CP4 repair or replacement at a GM-authorized dealership on or after May 6, 2025, as described above in FAQ 11.  Then you can complete the Reimbursement Request Form. If you cannot complete the form online, you can download it from the Important Documents page or email or call the Settlement Administrator to request that a copy be mailed or emailed to you.  

The deadline to file a Reimbursement Request Form is 60 days after the date the repair was performed. The Reimbursement Program will be available until May 6, 2026 or until the date the truck reaches 200,000 miles, whichever occurs first. The 12-month future warranty period will begin May 6, 2025.

GM-authorized dealerships cannot reimburse you for these repairs or answer questions about the Reimbursement Program. You can only receive cash-back reimbursement by submitting the Reimbursement Request Form along with all required documentation to the Settlement Administrator. If you have questions about the Reimbursement Program, please contact the Settlement Administrator at info@GMFuelPumpLitigation.com or 1-866-848-0815.

If you believe your truck needs a CP4 repair and is within the qualifying time/mileage requirements, you should contact your local GM-authorized dealer to find out how long they will need to have your truck so you can schedule the appointment at a time that is convenient for you, as the dealer may not provide a loaner or rental vehicle. This will also allow the dealer to order parts if they are not already in stock.

Payments will be sent to Class Members with approved Reimbursement Requests within 60 days of the form’s submission.

Yes. The Future Warranty Coverage will transfer with your truck for the duration of the warranty period, subject to the time and mileage limits described in FAQ 11. 

No amount of the Settlement Funds will be returned to GM. If there are any funds that remain after paying all Class Members with valid claims and other settlement costs, and if it is not feasible and/or economically reasonable to distribute the remaining funds to eligible Class Members, then the remaining balance will be paid to charitable causes that indirectly benefit the Class.

Unless you excluded yourself, you will be part of the Settlement Class. By staying in the Settlement Class, you will be eligible for all settlement benefits described in the Notice, and you will release GM and all Released Parties from any liability, cause of action, claim, right to damages or other relief, and any other legal rights to which you may otherwise be entitled under the law(s) of your state or any other applicable law, relating to the CP4 pump in your truck. By staying in the Settlement Class, you will give up your right to be a part of any lawsuit or arbitration, or pursue any claim, against GM and any Released Parties relating to the claims in this lawsuit. Staying in the Class also means that all of the Court’s orders will apply to you and legally bind you. 

This settlement does not release any claims for death, personal injury, damage to property (other than damage to the Class Truck related to a qualifying condition), or subrogation.

The scope of the claims and causes of action being released and the parties being released are outlined in Section VII of the Settlement Agreement, available on the Important Documents page should you wish to review it. You may also contact Class Counsel, listed below in FAQ 20, with any questions you may have. 

The deadline to exclude yourself from the Settlement was December 12, 2024, and has passed. 

No. If you did not send your request for exclusion before the December 12, 2024, or if you failed to include the required information, you remain a Class Member and will not be able to sue GM about the claims that the Settlement resolves. If you did no exclude yourself from the Settlement, you are bound like all other Class Members by the Court’s orders and judgments in this class action lawsuit, even if you do not file a claim.

No. You will not get money from the Settlement if you excluded yourself. If you excluded yourself from the Settlement, do not submit a Claim Form asking for benefits from the Settlement. 

Yes. The Court has appointed the law firms of Hagens Berman Sobol Shapiro LLP, Hilliard Martinez Gonzalez LLP (n/k/a Hilliard Law), and The Miller Law Firm P.C. to represent Plaintiffs and the Class Members in this Action. These law firms are known as “Class Counsel,” and they are listed below.  

Class Counsel asked the Court to award reasonable attorneys’ fees and expenses up to $15,000,000 including costs, for litigating this case and securing this settlement for the Settlement Class. These attorneys’ fees and expenses are completely separate from the $35 million available to Settlement Class Members discussed in FAQ 5 above. The Court approved Class Counsel’s request for fees, expenses, and service awards.

Class Counsel asked the Court for service awards of $5,000 for each of the 11 Class Plaintiffs who have conditionally been approved as Settlement Class Representatives (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), for their initiative and effort in pursuing this litigation for the benefit of the Settlement Class. Service awards will not affect the $35,000,000 fund for Class Member payments.

The deadline to object to the Settlement was December 12, 2024 and has passed. 
 

Objecting is simply telling the Court that you do not like something about the Settlement. You can object only if you stay in the Settlement Class, in which case you will be bound by the Court’s final ruling. Excluding yourself is telling the Court that you do not want to be part of the Settlement Class and the Settlement. If you exclude yourself, you have no basis to object because the case no longer affects you.

The Final Approval Hearing was held April 25, 2025. 

The Court held a Final Approval Hearing in Courtroom 709 of the United States District Court for the Eastern District of Michigan, Theodore Levin U.S. Courthouse, 231 W. Lafayette Blvd., Detroit, Michigan 48226. At this hearing the Court considered whether the Settlement was fair, reasonable, and adequate. If there were objections, the Court considered them. The Court issued Final Approval of the Settlement on May 6, 2025. 

No. Class Counsel answered questions the Court may have had. However, you were welcome to come at your own expense. If you sent an objection, you did not have to come to Court to talk about it. As long as your written objection was timely, the Court considered it. You may have also attended or paid your own lawyer to attend, but it was not required.

Yes. If you did not exclude yourself, you may have asked the Court’s permission to speak at the hearing. If you intended to appear at the Final Approval Hearing personally or through counsel, you or your attorney must have filed with the Clerk of the Court and serve on all counsel identified in FAQ 20 a notice of intention to appear at the hearing. The notice of intention to appear must have include copies of any papers, exhibits, or other evidence and identity of witnesses that would have been presented at the hearing. Your notice of intention to appear must have been postmarked by December 12, 2024.

If you did nothing, you will be bound by the Settlement if the Court approves it and release the claims described under Section 2.24 of the Settlement Agreement. Unless you are paid directly, you must file a claim to seek a payment. 

No. The Settlement was approved May 6, 2025.
