Mercedes Sold 200,000+ Cars That Violated Emissions Standards and Caused Thousands of Tons of Excess Air Pollution
Attorney General Schwalb today joined a coalition of 50 attorneys general announcing a $149,673,750 settlement with Mercedes-Benz USA and Daimler AG (Mercedes) for deceptively marketing, selling, and leasing more than 200,000 diesel vehicles in the United States, including approximately 380 vehicles registered in the District of Columbia, that violated DC and federal emissions standards and resulted in thousands of tons of excess air pollution.
The attorneys general allege that Mercedes designed and deployed software defeat devices intended to allow vehicles to effectively cheat emissions testing-allowing cars and vans to pass tests, even when they exceeded air pollution limits in normal, real-world operation. They also concealed the defeat devices-and the true levels of air pollution produced by their diesel vehicles-from the public and from state and federal regulators. Now, under the terms of a settlement agreement, Mercedes will pay significant penalties to the states, including $250,000 to the District, repair the affected vehicles that remain on the road so they meet emissions standards moving forward, and pay $2,000 in restitution to impacted consumers who have approved emission modification software installed by Mercedes on their vehicles.
"My office will not allow companies to profit by cheating the system, lying to consumers, or polluting our environment," said Attorney General Schwalb. "This bipartisan investigation and settlement holds Mercedes-Benz USA and Daimler AG accountable for years of fraud and sends a strong message that this type of deceptive and illegal behavior is unacceptable anywhere and at any time."
From 2008 through 2016, the states allege that Mercedes manufactured, marketed, advertised, and distributed more than 211,000 diesel passenger cars and vans equipped with software defeat devices that optimized emission controls during emissions tests, while reducing control of emissions during normal operations. The states allege that, when operated outside of emissions tests, these vehicles can emit many times the legal limits of nitrogen oxides (NOx), a harmful pollutant that causes respiratory illness and that contributes to the formation of smog. Mercedes allegedly engaged in this conduct to avoid implementing available NOx control technologies, which can decrease fuel efficiency and may require additional maintenance.
Mercedes violated DC consumer protection laws by:
Under the terms of a multistate settlement agreement, Mercedes is required to:
The company must also comply with reporting requirements and reforms to their practices, including a prohibition on any further unfair or deceptive marketing or sale of diesel vehicles, or misrepresentations regarding emissions and compliance.

Automaker Fiat Chrysler and its subsidiaries paid $72.5 million to the states in 2019. Bosch paid $98.7 million in 2019. Volkswagen reached a $570 million settlement with the states in 2016.
