(Antranik Tavitian/Detroit Free Press/TNS) General Motors said Thursday it is now able to increase vehicle deliveries to its dealers and customers in the United States and Canada despite a massive shortage of semiconductor chips, and that means most of its U.S. assembly plants will not take traditional summer shutdown. Shipments of Chevrolet Colorado and GMC Canyon midsize pickups built at Wentzville Assembly in Missouri will increase by about 30,000 total units through the week of July 5. Other vehicles are expected to see more deliveries to dealers soon, too.
