April 16 (UPI) -- Tesla has halted production of its Model 3 sedan for the second time just days after CEO Elon Musk said he would try to speed up production of the long-awaited vehicle. Tesla employees told Buzzfeed News that the pause came without warning and would last up to five days. Employees affected by the production pause will have to use vacation pay or stay home without pay if they can't be found work elsewhere in the Fremont, Calif. factory. Dennis Virag, an automotive manufacturing consultant, told the Wall Street Journal that halting production is an unusual step for a car manufacturer. "It's unheard of in this day and age," Virag said. Tesla's first production pause came in February.
