There’s nothing wrong with GM’s popular diesel engine (unlike the Chevy Bolt’s batteries). In an age of endless production woes, though, The Drive reports that a part supplier for the 3.0 Duramax is unable to supply their parts, which has brought production of the entire engine line to a screeching halt.

GM uses this engine in the Chevy Silverado and GMC Sierra pickups, Chevy Tahoe and Suburban SUVs and the Express van, the GMC Yukon and Yukon XL, and the Cadillac Escalade.

No other engines are thought to be affected by the part shortage. GM believes the issue is only temporary and should be solved soon. In an age of “just in time” delivery, though, with few parts actually on hand, this is what happens when there’s even a small hiccup in the system. Between chip shortages and COVID-19, there are many worse problems than small hiccups in the supply line right about now.
