Among the victims of the volcanic ash cloud was Ford, which had to close two plants because of parts shortages: the Mustang plant in Flat Rock, Mich. (where the Mazda6 is also made), and the Focus plant in Wayne, Mich.
Elsewhere, parts shortages led to a weeklong shutdown at BMW’s plant in South Carolina because the transmissions and other components coming from Germany couldn’t get off the ground.
The supply chains for automotive parts are long and complex and often involve the kind of trans-Atlantic flights that were completely shut down by the volcanic ash cloud. Though that cloud has now cleared, geologists fear another eruption could be triggered in the coming months.
