Auto-industry supplier BorgWarner (NYSE: BWA) said that it expects to resume limited production at a tornado-damaged South Carolina factory in early May. The factory makes critical parts for four-wheel-drive versions of pickup trucks and SUVs made by automakers including Ford (NYSE: F), Fiat Chrysler Automobiles (NYSE: FCAU), and Toyota (NYSE: TM). The factory, in Seneca, South Carolina, suffered severe damage from a tornado strike on April 13 that killed one employee, a security guard who had been stationed outside.
