Ford under investigation in US over emissions certification problems

As part of Ford's latest regulatory filing with the Securities and Exchange Commission (SEC), the company announced there was a "potential concern involving its US emissions certification process". Ford says it voluntarily informed the Environmental Protection Agency (EPA), California Air Resources Board (CARB) and other agencies about the matter in the middle of February this year. As a result, the US Department of Justice has also opened up a criminal investigation into the matter.
