What happened
Plaintiff Cory Hazdovac filed this class action against Mercedes-Benz USA, LLC alleging that MBUSA did not identify 14 vehicle parts as "high-cost" or "high-priced" emissions warranty parts (HPP) as required by the California Emissions Warranty regulations (California Code of Regulations Title 13, sections 2035 et seq.) and adopted by 16 other Section 177 States. Under the HPP Warranty, those parts should be covered for 7 years or 70,000 miles, whichever comes first, but were instead treated as covered only by the standard 4 years/50,000 miles new-vehicle warranty.
MBUSA denies the allegations and denies any wrongdoing or liability, and the Court has not made any determination that MBUSA violated any law. The parties agreed to settle to avoid the cost, risk, and time of continued litigation. As part of the Settlement, MBUSA agreed to reimburse 50% of out-of-pocket Qualified Repair costs and 100% of out-of-pocket Qualified Diagnosis costs incurred between 4 years/50,000 miles and 7 years/70,000 miles, and to provide 100% HPP Warranty coverage for the 14 Subject Parts on a going-forward basis.

Where the money is going
There is no common settlement fund. Reimbursement and going-forward HPP coverage are paid by MBUSA on a per-claim basis as Qualified Repairs and Qualified Diagnoses are submitted, with no aggregate cap on payouts to the class. Attorneys' fees, expenses, and the Class Representative service award are paid separately by MBUSA, subject to Court approval, and do not reduce any class member's recovery.
All amounts listed above are subject to final court approval at the June 25, 2026 Fairness Hearing. The Court may award less than the amounts requested. Reimbursement is offset by any goodwill, extended warranty, or other coverage already provided for the same repair or diagnosis (no double recovery).
Common questions
How much money will I receive?
There is no common fund and no per-claimant cap. Mercedes-Benz USA reimburses 50% of out-of-pocket costs for Qualified Repairs (parts, labor, and diagnosis) and 100% of out-of-pocket costs for Qualified Diagnoses (labor and diagnosis only, where you did not also repair or replace the part) on the 14 Subject Parts, performed at an Authorized Service Center between 4 years/50,000 miles and 7 years/70,000 miles. Reimbursement is offset by any goodwill, extended warranty, or other coverage already received for the same repair, so there is no double recovery. On a going-forward basis, MBUSA also provides 100% HPP Warranty coverage for the same 14 parts under the same mileage and time window.
Do I need to submit proof of purchase?
Yes. You must submit four items with your Reimbursement Claim Form: an itemized repair order or invoice showing the Subject Part was repaired, replaced, or diagnosed and the cost; proof of payment (credit card statement, paid invoice, or receipt); proof of ownership or lease of the Subject Vehicle at the time of the repair; and proof that the vehicle was registered in a covered Section 177 State at the time of the claimed repair or diagnosis. Repairs subject to standard HPP Warranty exclusions (for example, odometer tampering, accident damage, abuse, or neglect) do not qualify.
What if I didn’t receive a notice?
You can still file a Claim Form even if you did not receive a direct notice, as long as you meet the eligibility requirements and submit the required documentation. For help, visit HazdovacEmissionsWarrantySettlement.com or call the Settlement Administrator at 1-844-459-3177.
Does staying in the class affect my right to sue later?
Yes. The deadline to opt out was April 30, 2026 and has passed. If you did not submit a written exclusion request by that date, you remain a Settlement Class Member and will be bound by the Settlement and its release. That means you cannot separately sue MBUSA or the other Released Parties about the legal claims at issue in this lawsuit. The full release is in the Settlement Agreement at HazdovacEmissionsWarrantySettlement.com.
When will payments be sent out?
The Court will hold the Fairness Hearing on June 25, 2026 at 1:30 p.m. PT before Chief Judge Richard Seeborg in San Francisco. Reimbursement payments will only be issued after the Court grants final approval and any appeals are resolved. The appeal process can take a year or more. The going-forward HPP coverage for the 14 Subject Parts also begins on the Effective Date. No action is required after a valid Claim Form is submitted, just check HazdovacEmissionsWarrantySettlement.com for updates.
