A General Motors spokeswoman told a web forum that production of one type of Duramax engine has been halted temporarily due to supply chain problems, but plants in Moraine and Brookville are not affected, another GM representative said Monday.

A post on PickupTruckTalk.com said Monday that production of the 3.0 liter Duramax engine was temporarily halted, which a GM spokesman confirmed to the Dayton Daily News.

“DMAX in Moraine is not being impacted at all,” GM spokesman Daniel Flores said. “They’re still running regular production.”

The DMAX plant in Moraine, owned by General Motors and Isuzu, produces the 6.6-liter Duramax engine.

The 3-liter engine, built in Michigan, instead is temporarily impacted. “We stopped production due to a parts shortage,” Flores said.

The recently built Brookville DMAX plant operates concurrently with the original DMAX plant in Moraine, sending the Moraine plant machined engine components.

From Moraine, finished diesel engines go to a GM plant in Flint, where the engines are built into the new Chevrolet Silverado and GMC Sierra HDs (heavy duty) trucks.

DMAX in Moraine has about 800 workers.

The site quotes Megan Soule, a spokeswoman for Chevrolet trucks and SUVs.

“The 3.0-liter Duramax diesel is not being discontinued,” Soule is quoted as saying there. “We have currently paused production of trucks with that engine due to a temporary part shortage. We will resume production with the 3.0-liter Duramax diesel as soon as possible.”
