The pickups have been among the industry’s fastest-selling vehicles this year. The Colorados were selling in an average of 24 days last month, a GM spokesman said. The Canyon’s turn rate was 37 days.
GM has been scrambling for the past year to squeeze more production out of the plant. It has been working three shifts and on weekends, with workers even agreeing to rejigger their break times to eliminate a six-minute lull between shifts.
GM previously contracted with AM General to build its Hummer H2 SUV, which was in production from 2002 to 2009.
