Just weeks after starting production of the new 2011 heavy-duty pickup trucks at the Flint, MI assembly plant, General Motors suspended work last Thursday to replace a defective component. Engineers found a problem with the unidentified part during routine testing and immediately found a replacement. Three shifts of Chevrolet Silverado and GMC Sierra HD production were canceled on Thursday and Friday, but assembly is scheduled to resume on Monday morning.
Trucks that have already been built and shipped to dealers over the past four weeks will also be retrofitted before customer delivery. In July, GM will also add production of light-duty pickups at Flint.
