What Is the Mercedes-Benz Lawsuit About? Hazdovac v. Mercedes-Benz USA, LLC et al., No. 3:20-CV-377

The lawsuit alleged that Mercedes-Benz USA failed to identify 14 vehicle parts as “high-cost” or “high-priced” emissions warranty parts under the requirements of the California Emissions Warranty — meaning those parts should have been covered for seven years or 70,000 miles at no cost to owners, but were not.

The specific law at issue is California Code of Regulations, Title 13, §§ 2035 et seq., which governs the California High-Priced Parts (HPP) Warranty. Under this regulation — adopted by 17 states through Section 177 of the federal Clean Air Act — automakers must cover certain expensive emissions-related components for seven years or 70,000 miles, whichever comes first. The plaintiff argues Mercedes-Benz deliberately left 14 parts off its HPP Warranty list to limit the company’s own exposure to warranty claims. That decision, the lawsuit says, left owners holding repair bills they should never have received.

If you owned or leased a 2015 or newer Mercedes-Benz, paid for a repair at a dealership, and later wondered why your warranty did not cover it — this case may be the answer. For related reading, see our guide to product defect and warranty class action lawsuits on AllAboutLawyer.com.

Who Qualifies for the Mercedes-Benz Emissions Warranty Settlement?

You are a Settlement Class Member if you are a person, in a Section 177 State, who purchased or leased a Mercedes-Benz vehicle between model year 2015 and the present that is covered by an HPP Warranty.

Here is how to know if you are in:

You may qualify if:

• You own or leased a model year 2015 or newer Mercedes-Benz vehicle
• Your vehicle was registered in one of the 17 covered states: California, Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, or Washington
• You paid out of pocket to diagnose, repair, or replace one of the 14 covered emissions parts
• The repair or diagnosis took place after your vehicle’s 4-year/50,000-mile warranty expired but before the 7-year/70,000-mile threshold — the window where the HPP Warranty should have applied
• The work was performed at an authorized Mercedes-Benz dealership or service center

You likely do NOT qualify if:

• Mercedes-Benz, your extended warranty provider, or any other party already covered the cost of the repair — there shall be no double recovery; any goodwill or extended warranty coverage received offsets the reimbursement available under this settlement
• Your vehicle is not a model year 2015 or newer
• Your vehicle was not registered in one of the 17 covered states
• You have no documentation showing you paid for the covered repair or diagnosis

The 14 covered parts are: Manifold PCV Connection Assembly, Power Train Control Unit (PCM), Accelerator Pedal Sensor, Accelerator Pedal, Partial Load Operation Crankcase Ventilation Valve, Clean Air Line, Pressure Sensor Downstream of Air Filter, Check Valve within the EVAP System, Crankcase Ventilation System, Vent Control Valve, Charcoal Canister, Fuel Tank Level Indicator Fill Level Sensors, Coolant Thermostat, and ESP Electronic Stability Program Control Unit. You can check the full list with descriptions at the official Eligible Vehicle Parts page.

How Much Can You Get from the Mercedes-Benz Settlement?

Your reimbursement depends on what work was done and what you paid. MBUSA agreed to reimburse up to 50% of out-of-pocket expenses for qualified repairs, limited to the cost of parts, labor, and diagnosis. For diagnosis only — where you got the car checked but did not have the repair performed — MBUSA agreed to reimburse up to 100% of out-of-pocket diagnosis costs.

The settlement does not have a fixed fund or cap — Mercedes-Benz is required to pay every valid claim based on the actual amounts documented. Your payment depends entirely on what you paid and what proof you submit.

To give you a practical sense of the legal settlement payout: if you paid $800 out of pocket for a covered repair, you receive $400 back. If you paid $350 for a diagnosis that did not lead to a repair, you receive the full $350 back. There is no minimum reimbursement threshold — if you paid $300 for a covered repair, you get $150 back.

Going forward, MBUSA also agreed to provide 100% coverage for the cost to repair, replace, or diagnose a subject part at an authorized service center between the 4-year/50,000-mile and 7-year/70,000-mile warranty period on vehicles registered in Section 177 states — and class members will not need to present any settlement-related documentation to receive that coverage at a dealership.

Is there a class action lawsuit against Mercedes-Benz for warranty issues? 

Yes. Hazdovac v. Mercedes-Benz USA, LLC et al., Case No. 3:20-CV-377, was filed in the U.S. District Court for the Northern District of California and alleges that MBUSA failed to classify 14 emissions parts as High-Priced Parts under California’s emissions warranty law, forcing owners to pay for repairs they should not have owed.

How much will I get from the Mercedes-Benz settlement? 

You can receive 50% of your out-of-pocket repair costs or 100% of your diagnosis-only costs, based on documented expenses. There is no fixed cap — every valid claim is paid individually based on what you actually paid. You need your itemized invoice and proof of payment to file.

Do I need a lawyer to file a claim? 

No. You can file directly through the official claim portal at no cost. If you want to understand your full options or explore whether a defective product lawsuit or individual claim makes more sense for your situation, a product liability attorney can offer a free consultation.

Is this settlement legitimate?

 Yes. The case is pending before Chief Judge Richard Seeborg in the U.S. District Court for the Northern District of California. The settlement is administered by Postlethwaite & Netterville, a court-appointed claims administrator. The only official website is HazdovacEmissionsWarrantySettlement.com — do not share your vehicle or personal information with any other site.

When will I receive my Mercedes-Benz settlement payment?

 The settlement administrator will issue payments within 30 days of the final decision regarding each individual claim — unlike many settlements that distribute all payments at once after final approval, this settlement can process and pay claims on a rolling basis.

What if I lost my repair invoice?

 Contact the Mercedes-Benz dealership or authorized service center where the repair was performed — they keep service records on file. You can also check your credit card or bank statements for proof of payment. If you still cannot locate documentation, call the settlement administrator at 1-844-459-3177 for guidance before the May 15, 2026 deadline.

Will this settlement payment affect my taxes?

 Settlement reimbursements for vehicle repair costs may be treated as a reduction of those expenses rather than income, depending on your tax situation. Consult a qualified tax professional for advice specific to your circumstances, particularly for larger reimbursements.
