Production of the best-selling combo of vehicles in the US has just been put on hold. A new report says that General Motors is planning to stop production of the GMC Sierra and the Chevrolet Silverado pickups at its assembly plant in Silao, Mexico. While production stoppages, especially in the summer, are not unusual, this extended shutdown seems like it could be something different. When combined, the mechanically identical Silverado and Sierra outsell Ford’s F-Series, America’s best-selling vehicle for decades now.
