Applies to California, Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, Nevada, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, Virginia, Washington
Main deadline May 15, 2026 (for repairs or diagnoses that occurred before March 16, 2026). For repairs or diagnoses that occur after March 16, 2026 but before the settlement effective date, submit within 60 days of the repair or diagnosis date.
Benefit 50% reimbursement for out-of-pocket repair costs and 100% reimbursement for standalone diagnosis costs for covered parts; plus ongoing warranty coverage for those parts going forward.

What happened

Class period: Model year 2015 to present (coverage start date varies by state). Repairs or diagnoses must have occurred after the vehicle's 4-year/50,000-mile warranty expired and before the 7-year/70,000-mile warranty limit.

  • Plaintiff sued Mercedes-Benz USA, LLC (MBUSA) alleging that 14 specific vehicle parts in Mercedes-Benz cars should have been classified as "high-priced" emissions warranty parts (HPP) under California law -- meaning they should have been covered for 7 years or 70,000 miles, whichever comes first
  • Because MBUSA allegedly did not classify these parts as HPP parts, owners and lessees in California and other Section 177 states were not notified of this extended warranty coverage and paid out of pocket for repairs and diagnoses that should have been covered
  • The 14 subject parts include components such as the Power Train Control Unit, Coolant Thermostat, Charcoal Canister, Accelerator Pedal, Crankcase Ventilation System, and ESP Electronic Stability Program Control Unit, among others
  • MBUSA denies all wrongdoing and denies that the parts were improperly classified
  • The settlement covers owners and lessees of model year 2015 and newer Mercedes-Benz vehicles registered in California or the other 16 Section 177 states that adopted California's emissions warranty requirements

What you can get

50% reimbursement for out-of-pocket repair costs and 100% reimbursement for standalone diagnosis costs for covered parts; plus ongoing warranty coverage for those parts going forward.

FAQ

What is this lawsuit about?
Plaintiff alleges that Mercedes-Benz USA, LLC failed to classify 14 specific vehicle parts as "high-priced" emissions warranty parts under California law.

How much money can I get?
If you paid out of pocket for a covered repair or replacement, you may receive 50% of your out-of-pocket costs. If you paid only for a diagnosis and did not have the part repaired at an authorized center, you may receive 100% of that diagnosis cost. Amounts vary based on your actual costs and supporting documentation.
What if I have not had a repair yet but my vehicle might need one?
Once the settlement is effective, MBUSA will provide 100% coverage going forward for repairs, replacements, or diagnoses of the 14 subject parts at an authorized Mercedes-Benz service center, as long as your vehicle is within the 7-year/70,000-mile warranty window. You do not need to submit a claim to receive this going-forward coverage.
