On May 18, 2026, the California Air Resources Board (CARB) announced that Volvo has agreed to pay the state nearly $197 million as a settlement for alleged violations of emissions and certification requirements for some of its vehicles that were sold in California.
The settlement consists of approximately $18 million in penalties and costs, $71 million towards mitigation of the air quality harm caused by the violations, and an additional $108 million toward emission reduction projects throughout the state.
The settlement was the result of Volvo using undisclosed auxiliary emission control devices (AECD) that violated state requirements. These devices were used in approximately 10,000 Volvo diesel engines for model years 2010 through 2016. CARB alleged that the AECDs were not adequately disclosed during the required emission certification process, a major violation of California's heavy-duty engine regulations.
As a result, these engines emitted more smog forming nitrogen oxides (NOx) emissions than allowed by law.
Also, as part of the settlement, Volvo agreed to recall, repair, and extend warranties to address the non-compliant AECDs for model year 2014 through 2016 diesel engines.
Said CARB Chair Lauren Sanchez, “This case underscores why CARB's compliance testing and strong enforcement are essential to protecting the state's air quality and public health. Our responsibility goes beyond adopting regulations — we are committed to upholding them by identifying violations and holding companies accountable for meeting emissions standards.”
