Yes, Mercedes-Benz owners may qualify for reimbursement if they paid out of pocket for repairs to specific emissions system parts between 2015 and the present. A settlement called the Hazdovac Emissions Warranty Settlement could entitle you to recover up to 50% of repair costs for certain high-cost emissions parts that Mercedes allegedly should have covered under warranty. If you own a 2015 or newer Mercedes-Benz (non-electric) registered in one of 17 states that follow California emissions standards, and you paid for repairs to affected emissions components after your standard warranty expired, this settlement may apply to you.
The settlement addresses a specific practice: Mercedes allegedly intentionally omitted 14 high-cost emissions warranty parts from warranty booklets to reduce warranty claim exposure, in violation of California law that requires automakers to properly classify and cover expensive emissions components. The settlement has already received preliminary approval from the court as of December 4, 2025, and is scheduled for final approval hearing on June 25, 2026.

Are You Eligible for This Mercedes Emissions Warranty Reimbursement?
Eligibility hinges on three main factors: the year and type of your mercedes, your state of registration, and whether you paid out of pocket for specific repairs. The settlement covers all Mercedes-Benz models from 2015 and newer, excluding electric vehicles, that are registered in one of 17 states with california emissions standards (states that have adopted California’s more stringent emissions rules).
Your vehicle must have been registered in one of these covered states at the time of the repair for which you’re claiming reimbursement. For example, if you own a 2018 Mercedes C-Class registered in New York and paid $800 for an emissions component repair in 2022, you would likely be eligible to pursue a claim. However, if your vehicle is registered in a state that does not follow California emissions standards, such as Wyoming or South Dakota, you would not qualify, even if the repair was done at an authorized Mercedes service center.
What Are the 14 Specific Emissions Parts Covered by This Settlement?
The settlement covers 14 specific high-cost emissions warranty parts that Mercedes allegedly failed to properly classify in its warranty documentation. These are components critical to controlling vehicle emissions and reducing pollution, parts that typically carry premium replacement costs when they fail after your standard four-year, 50,000-mile warranty expires. Under the emissions warranty period of seven years and 70,000 miles—a requirement established by California law—these parts should have been explicitly covered, and Mercedes customers should not have been left paying full repair costs out of pocket.
However, not every emissions-related repair will qualify. The settlement specifically addresses the 14 identified parts; repairs to other emissions components, even if expensive, would not be covered under this agreement. Additionally, only out-of-pocket repairs performed at authorized Mercedes-Benz service centers count toward reimbursement. If you took your vehicle to an independent shop or if Mercedes covered the repair under another program, that claim would not qualify.
How Much Money Can You Get Back?
The reimbursement structure is straightforward: if you paid out of pocket for repairs to covered parts at an authorized Mercedes service center, you can recover up to 50% of what you paid. For diagnosis-only claims—meaning you paid just for the diagnostic work to identify the problem but did not proceed with the repair—you receive 100% reimbursement of the diagnosis cost. This distinction matters because some customers may have paid a dealer to diagnose an issue, decided the repair was too expensive, and lived without the repair; those diagnostic costs are fully reimbursed.
For example, imagine you paid $1,200 to have a covered emissions part replaced at a Mercedes dealer in 2023, well within the seven-year, 70,000-mile emissions warranty window but after your standard warranty ended. Under this settlement, you could recover up to $600 (50% of $1,200). By contrast, if you paid $150 just to have the part diagnosed as faulty but didn’t authorize the repair, you would recover the full $150. The reimbursement is capped, meaning there is a maximum amount per claim, though the exact limits depend on the part in question and other case-specific details.
How Do You File a Claim and What’s the Deadline?
To pursue a claim, you’ll need to visit the official settlement website at HazdovacEmissionsWarrantySettlement.com, where you can submit your repair documentation and eligibility information. You’ll need to provide proof that you own or owned a qualifying Mercedes-Benz, documentation showing your repair was performed at an authorized Mercedes service center, and receipts or invoices showing what you paid. The critical deadline is May 15, 2026, for claims relating to repairs performed before the settlement received court approval (pre-notice repairs); after that date, claim windows may tighten or additional requirements may apply.
The timeline is tight but manageable. Gather your service records now if you believe you qualify. If you no longer have paper receipts, contact the Mercedes service center where the work was done; they maintain digital records and can provide documentation. The settlement website will walk you through the submission process step by step, and there is no filing fee to submit your claim.
What You Need to Know About the Repair Center Requirement
One important limitation: only repairs performed at authorized Mercedes-Benz service centers qualify for reimbursement. If you took your vehicle to an independent mechanic, a non-franchised shop, or an out-of-network repair facility, even if they performed identical work, those repairs do not qualify. This requirement is central to the settlement agreement and reflects the specific terms that Mercedes negotiated. Mercedes dealers keep records of all warranty work performed, which makes documentation and verification easier for the settlement administrator.
There’s also a critical difference between repairs done before the settlement received preliminary approval and those done after. Repairs completed before December 4, 2025, fall under the “pre-notice” category and have a May 15, 2026 filing deadline. If your repair was done after December 4, 2025, different deadlines may apply, and you should check the settlement website for the specific rules governing post-notice claims. Missing the deadline for pre-notice repairs could mean forfeiting your reimbursement entirely, which is why moving quickly matters.
Why Was Mercedes Sued Over This Warranty Practice?
The lawsuit alleged that Mercedes intentionally omitted the 14 high-cost emissions parts from its warranty booklets and literature, despite being required by California law to designate such expensive emissions components as warranty-covered items. By leaving these parts off official warranty documentation, Mercedes shifted repair costs to customers who reasonably believed their emissions systems were covered during the full seven-year emissions warranty period. The settlement represents an acknowledgment that this practice violated the law, though Mercedes did not admit wrongdoing as part of the agreement.
This practice affected thousands of owners across 17 states. Over time, individual owners each paid hundreds or thousands of dollars for repairs they reasonably thought were covered under the manufacturer’s warranty. The class action mechanism allows these individuals to recover collectively, rather than each person pursuing a separate small claim against a major corporation.
What’s Next—Final Approval and Settlement Timeline
The settlement is currently in its approval phase. Preliminary approval was granted on December 4, 2025, and a final approval hearing is scheduled for June 25, 2026. During this period between preliminary and final approval, claim filing windows are open to eligible owners.
Once the court gives final approval, the settlement moves into payout phase, where the settlement administrator will process claims and distribute reimbursements to qualifying applicants. The fact that final approval hasn’t yet occurred should not deter you from gathering your documentation and preparing your claim now. All pre-notice repairs (those completed before December 4, 2025) have until May 15, 2026 to be claimed, which is before the final approval hearing. Being prepared and filing early reduces the risk of missing deadlines and ensures your claim is in the queue before final approval.
