Mercedes-Benz will pay $149.7 million to settle claims that it intentionally cheated on diesel emissions tests, misleading consumers and violating environmental regulations across the United States. The agreement, reached with a bipartisan coalition of state attorneys general, brings fresh scrutiny to the automaker’s practices following similar scandals involving Volkswagen.
How the Cheating Worked
Between 2008 and 2017, Mercedes equipped over 211,000 diesel vehicles with undisclosed software designed to artificially lower emissions during testing. In real-world driving, these vehicles emitted up to 40 times the legally allowed levels of nitrogen oxide (NOx). This deception allowed Mercedes to falsely advertise its diesel cars as “clean” and “low-emission,” while circumventing regulations.
The vehicles used what regulators call an “Auxiliary Emissions Control Device” (AECD) which detected when the car was undergoing testing. During tests, the AECD activated a more compliant emissions mode. Outside of the lab, the vehicles reverted to a high-emission mode to maximize performance and fuel economy.
Terms of the Settlement
Under the agreement, $120 million will be allocated to states for air pollution prevention and abatement programs. An additional $29.7 million penalty is suspended, contingent on the automaker repairing, buying back, or removing affected vehicles from the road. Mercedes will offer $2,000 to owners who get an approved emissions modification by September 30, 2026.
The settlement also prohibits Mercedes from selling diesel vehicles with illegal defeat devices and bans misleading emissions claims. The company must now provide regular reports on repair progress.
Models Affected
The affected vehicles include several popular Mercedes models from 2011 to 2016, such as the E350, GL-Class, GLE-Class, GLK-Class, ML-Class, R-Class, and S-Class. The Sprinter van is also implicated.
Why This Matters
The Mercedes scandal is a stark reminder of the industry’s willingness to prioritize profits over environmental responsibility. Automakers face increasing pressure to comply with stricter emissions standards, yet some continue to exploit loopholes. This case underscores the need for greater transparency and enforcement to protect public health and the environment.
Mercedes has already settled with the US Government for $2.2 billion in a separate case. The ongoing legal action highlights the lasting consequences of automotive fraud.
