In 2015, it was revealed that Volkswagen had been using a software "defeat device" that cheated emissions tests on its diesel cars. The company admitted that as many as 11 million of its vehicles were affected, and it eventually agreed to pay billions of dollars in fines and penalties to settle lawsuits related to the scandal.
