With Volkswagen’s emission crisis winding down (but seemingly never over), Daimler AG is taking center stage as the next automaker to potentially face serious hardship for dastardly diesel misdeeds. For the last few months, investigators from the United States and Germany have begun suspecting that Mercedes-Benz equipped its vehicles with defeat devices similar to those used by VW. While no evidence of fraud has surfaced, there’s reason to believe Daimler may have violated emission standards — especially now that it has decided to recall 3 million late-model diesels.

“The public debate about diesel engines is creating uncertainty,” Daimler CEO Dieter Zetsche said in a statement on Tuesday. “We have therefore decided on additional measures to reassure drivers of diesel cars and to strengthen confidence in diesel technology.”

After staying relatively clean in the ongoing diesel emissions scandal that’s keeping European automakers up at night, Mercedes-Benz now finds itself the potential target of an Environmental Protection Agency investigation, Automotive News Europe reports.

The EPA’s request for information targets the nitrous oxide emissions of the company’s Bluetec diesel engines, and comes less than two weeks after a class-action lawsuit was filed by law firm Hagens Berman (of General Motors ignition switch fame).

Yes, that sound you’re hearing is executives loosening their collars in Stuttgart.

The Mercedes-Benz ML is the latest victim of powertrain downsizing, but this time, it’s the diesel version that’s getting its cylinder count trimmed.
