For the first time since General Motors emerged from bankruptcy in 2009, the company has announced a new model truck to be produced at the Flint Assembly plant in Michigan.

The 3.7-million square foot facility is General Motors’ oldest manufacturing plant in the United States. Despite decades of factory closures that eliminated tens of thousands of jobs from the city, the Flint Assembly plant continues to thrive.

It survived 17 of GM’s plant closures around the country in recent years.

Instead of fretting about their future, Flint Assembly workers say they’re confident they’ve developed a successful formula that will keep the plant open for years to come. For the past two years, trucks made at the plant have received honors from J.D. Power and Associates for highest initial quality.

The company invested nearly $330 million preparing Flint Assembly for production of the 2015 Chevrolet Silverado and GMC Sierra heavy-duty pickup trucks, which are built with increased towing and hauling capability and improved safety features, according to Tom Wickham, a GM spokesman for the Flint area.

America Tonight went inside the plant to see what works inside the facility. Union workers and management suggested their collaborative and cooperative relationship has helped them succeed in their quest to build quality trucks that American people would want to buy.
