LANSING, Mich. (Michigan News Source) — Michigan drivers bought diesel vehicles marketed as clean and compliant. State officials say the fine print, hidden in software, told a different story.

Mercedes-Benz Group has agreed to pay nearly $150 million to settle a multistate lawsuit accusing the automaker of installing undocumented emissions software that allowed diesel vehicles to pollute more during everyday driving while still passing lab tests.

Attorney General Dana Nessel’s office says more than 2,700 vehicles sold or registered in Michigan were among the 211,000 diesel cars and vans nationwide affected by the alleged scheme, which spanned model years 2008 through 2016.

According to the settlement, Mercedes used software that temporarily boosted emissions controls during regulatory testing, then reduced them during normal operation—permitting nitrogen oxide emissions above legal thresholds, a pollutant linked to smog and breathing problems.

Mercedes will pay $120 million upfront, with an additional $29.7 million tied to a consumer relief program aimed at repairing or removing unrepaired vehicles still on the road. Michigan is slated to receive $805,067 from the agreement.

“Michigan car buyers expect and deserve honest advertising,” Nessel said.

Mercedes agreed to the settlement without acknowledging any wrongdoing, bringing the multistate case to a close.
