United States v. Hino Motors, Ltd.

On March 19, 2025, Hino Motors, Ltd. (HML) was sentenced to pay a criminal fine of $521.76 million, serve a five-year term of probation, during which it will be prohibited from importing any diesel engines it has manufactured into the United States, and implement a comprehensive compliance and ethics program and reporting structure. Additionally, the court entered a $1.087 billion forfeiture money judgment against the company.

HML was charged in a single conspiracy count with five objects: to defraud the Environmental Protection Agency, to defraud the National Highway Transportation Safety Administration, to violate the Clean Air Act, to commit wire fraud, and to smuggle goods into the United States, all in violation of 18 U.S.C. § 371.

Between 2010 and 2019, HML submitted and caused to be submitted false applications for engine certification approvals. Company engineers regularly altered emission test data, conducted tests improperly, and fabricated data without conducting any underlying tests. HML submitted fraudulent carbon dioxide emissions test data, which resulted in false fuel consumption values being calculated for its engines. Company engineers also failed to disclose software functions that could adversely affect engines’ emission control systems. As a result of the fraud, HML imported and sold more than 105,000 non-conforming engines between 2010 and 2022.

The U.S. Environmental Protection Agency Criminal Investigation Division and the Federal Bureau of Investigation conducted the investigation.
