Because of this situation, Toyota has decided to cease exports of its vehicles to Iran. The automaker issued a statement saying that this decision was made after considering "the international environment," and that it would "continue to closely monitor the international situation."
Toyota's sales in Iran have fallen drastically over the past few years – only around 220 vehicles were sold this year, up until the company's decision to remove Iran from its export list. This is indeed quite a change, as Toyota sold nearly 4,000 vehicles in Iran just two years earlier.
Currently, no American automakers have a presence in Iran, and with Toyota moving to stop exports to the country, we'll be interested to see if other manufacturers follow suit. Currently, major European automakers like Mercedes-Benz and BMW continue to export to Iran.
