Hawai‘i Joins $149.7 Million Multistate Settlement with Mercedes-Benz

On Dec. 30, 2025, a coalition of state enforcement authorities announced a $149,673,750 settlement with Mercedes‑Benz USA, LLC and Mercedes‑Benz Group AG to resolve claims that the company marketed, sold and leased vehicles equipped with defeat devices or other undisclosed software that circumvented emissions standards. The Hawai‘i Department of Commerce and Consumer Affairs’ Office of Consumer Protection joined the multistate action alongside 50 state attorneys general.

The settlement covers allegations that affected vehicles did not comply with regulatory or consumer expectations about emissions performance. Under the agreement, the total fund will be divided among the participating states and used to remedy consumer harm as well as finance enforcement and consumer‑protection programs. Specific allocations to Hawai‘i and the mechanics of any consumer relief were not detailed in the announcement shared by the department.

For Kaua‘i residents, the settlement matters because it is intended to provide redress and to bolster state capacity to pursue misconduct that can affect local motorists and the environment. Owners and lessees of Mercedes vehicles in Hawai‘i may be among those eligible for remedies depending on the final allocation and the claims process. The DCCA’s participation signals the state’s interest in ensuring consumers in Hawai‘i receive their share of enforcement outcomes and that agencies here retain resources to pursue future consumer protection work.

This multistate action follows broader regulatory scrutiny of automotive software and emissions compliance in recent years, reflecting international and national concerns about manufacturers’ disclosures and regulatory conformity. The settlement’s emphasis on remedying consumer harm and funding enforcement underscores a policy trend toward using recovered funds both to compensate affected individuals and to strengthen oversight capacities.

Kaua‘i residents with Mercedes vehicles should monitor announcements from the Hawai‘i Department of Commerce and Consumer Affairs for information on eligibility, filing a claim, and timing. Keep vehicle documentation, purchase or lease records, and service receipts accessible in case official notices request proof of ownership or service history. The department’s involvement provides a local point of contact for questions and next steps as the allocation and consumer relief details are finalized.
