The “HPP warranty” from Mercedes-Benz USA covered their vehicle. The warranty applies to high-priced, emissions-related parts between four years/50,000 miles and seven years/70,000 miles (excluding electric vehicles).
They paid out of pocket for the diagnosis, repair or replacement of any of the following “subject parts” between four years/50,000 miles and seven years/70,000 miles:

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
ESP control unit

Their payment for diagnosis, repair or replacement occurred between four years/50,000 miles and seven years/70,000 miles.

The model year coverage start date varies by state:

For California, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont and Washington, coverage starts with model year 2015.
For Colorado, coverage starts with model year 2022.
For Minnesota, Nevada and Virginia, coverage starts with model year 2025.

How much can class members get?

There are two main categories of reimbursement:

Qualified repair reimbursement: Consumers who paid for a repair or replacement of a covered part after their vehicle’s four-year/50,000-mile warranty expired but before the seven-year/70,000-mile warranty expired can claim 50% of their out-of-pocket costs (including parts, labor and diagnosis).
Qualified diagnosis reimbursement: Consumers who paid for a diagnosis of a covered part during the same period but did not proceed with a repair or replacement can claim 100% of their out-of-pocket costs for the diagnosis.

Additionally, after the settlement’s effective date, Mercedes-Benz USA will provide 100% coverage for the repair, replacement or diagnosis of these parts at authorized service centers for eligible vehicles within the seven-year/70,000-mile period.

Consumers who did not incur any out-of-pocket costs for a qualified repair or diagnosis before the effective date of the settlement will not be eligible for reimbursement. However, they may still benefit from the settlement’s forward-looking warranty coverage for the subject parts.

Why is there a class action settlement?

This lawsuit alleged Mercedes-Benz USA LLC failed to identify and cover 14 emissions-related parts as “high-priced parts” under California’s emissions warranty regulations. The plaintiff claimed the automaker should have covered these parts for seven years/70,000 miles but did not provide the required coverage.

Mercedes-Benz USA denies any wrongdoing but agreed to settle to avoid further litigation costs and uncertainty.
