Hazdovac v. MBUSA Settlement: Covered Parts, Claims, and Payouts

The Hazdovac v. MBUSA settlement is a proposed resolution of a class action against Mercedes-Benz USA alleging the automaker failed to classify fourteen emissions-related parts as “high-priced” under California’s emissions warranty rules, which would have extended their coverage to seven years or 70,000 miles. If the court grants final approval, owners and lessees of qualifying 2015-and-newer Mercedes-Benz vehicles registered in any of seventeen states can get 50% reimbursement for past out-of-pocket repairs on those parts, 100% reimbursement for diagnosis-only visits, and free coverage for future repairs on those parts through the 7-year/70,000-mile mark. Mercedes-Benz denies wrongdoing and settled to end the litigation.¹

Do You Qualify

The class includes anyone who purchased or leased a Mercedes-Benz vehicle of model year 2015 or later (excluding electric vehicles) that carries a high-priced-parts emissions warranty, so long as the vehicle was registered in one of seventeen states that follow California’s emission standards under Section 177 of the Clean Air Act.² Those states are California, Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, and Washington.³

Coverage does not begin in the same year everywhere. Most states are covered from model year 2015 on. Colorado-registered vehicles are covered starting with model year 2022, and Minnesota, Nevada, and Virginia starting with 2025.⁴

The Fourteen Covered Parts

The settlement applies only to work involving one of fourteen specific components the lawsuit alleged should have carried the extended 7-year/70,000-mile warranty:¹

Manifold PCV Connection Assembly
Partial Load Operation Crankcase Ventilation Valve
Crankcase Ventilation System
Clean Air Line
Pressure Sensor Downstream of Air Filter
Coolant Thermostat
Check Valve within the EVAP System
Vent Control Valve
Charcoal Canister
Fuel Tank Level Indicator Fill Level Sensors
Power Train Control Unit (PCM)
Accelerator Pedal Sensor
Accelerator Pedal
ESP Electronic Stability Program Control Unit

Repairs on other parts are not covered by this settlement, and only work performed at an authorized Mercedes-Benz service center qualifies.⁵

What You Can Recover

Two things are on offer: cash reimbursement for past repairs, and extended warranty protection going forward.

Past Repairs

If you already paid out of pocket at an authorized Mercedes-Benz service center for work on any of the fourteen parts, and the service happened after your standard 4-year/50,000-mile warranty ran out but before you hit 7 years or 70,000 miles, you can claim:¹

50% of your out-of-pocket cost for a repair or replacement, including parts, labor, and diagnostic charges.
100% of your out-of-pocket cost when the visit was diagnosis only (labor and diagnostic charges).

Extended Warranty Going Forward

Once the settlement takes effect, Mercedes-Benz will cover 100% of the cost of repairing, replacing, or diagnosing any of the fourteen parts on qualifying vehicles that are past the 4-year/50,000-mile mark but still within 7 years or 70,000 miles. The coverage attaches to the vehicle, so it transfers to a subsequent owner.¹

Deadlines and How to File

The deadline for claims covering repairs performed before March 16, 2026, was May 15, 2026, and that window has closed. For any qualifying repair or diagnosis performed on or after March 16, 2026, a claim must be filed within 60 days of the service date.⁵

To submit a claim, you complete the Reimbursement Claim Form and attach four items:⁵

Proof of the repair or diagnosis, such as an itemized repair order, invoice, or service documentation showing the covered part and the cost.
Proof of payment, such as a credit card statement, receipt, or zero-balance invoice.
Proof you owned or leased the vehicle at the time of service.
Proof the vehicle was registered in a covered Section 177 state at the time of service.

Claims can be submitted online, by email, or by U.S. mail to the settlement administrator.⁵

If You Did Nothing, or Opted Out

The opt-out deadline was April 30, 2026.⁵ Class members who did not opt out are bound by the settlement’s release of claims, meaning they cannot separately sue Mercedes-Benz over the fourteen parts covered here, whether or not they filed a claim. The release does not extend to personal injury claims, unrelated matters, or any contractual coverage that lasts beyond 7 years/70,000 miles.¹ Class members who validly opted out kept the right to sue on their own but are ineligible for any settlement benefits, including the extended warranty.

Approval Status and When Payments Arrive

Judge Richard Seeborg of the U.S. District Court for the Northern District of California granted preliminary approval on December 4, 2025.⁶⁷ If the court grants final approval, reimbursement payments are expected within 30 days of the final decision on each individual claim, and the extended warranty on the fourteen parts formally takes effect at the same point.⁴
