A shortage of parts from Mexico is hampering the General Motors Co.’s plans to increase its production of pickup trucks, according to a report by The Wall Street Journal that cited a union official and other people familiar with the matter. GM has postponed plans to add more shifts due to the shortage, according to the report. The auto maker doesn’t yet have the flow of parts it needs to accelerate production as planned, and it has postponed plans to call back roughly 1,300 workers to factories in Indiana and Michigan. A spokesperson for GM told the newspaper that the company continues to plan “to ramp up production in a gradual cadence,” without discussing scheduling specifics. Earlier this week, Ford Motor Co.
halted production at two plants in Illinois and Michigan also for reasons related to the coronavirus pandemic.
