The news broke on Friday September 18, 2015 that the EPA had accused Volkswagen of violating emission standards on TDI models from 2009-2015 because of software that was installed that manipulated emissions tests. At this time, Volkswagen is halting all sales of TDI models as an investigation takes place. There is no recall at the moment and all vehicles are safe to drive.
