Pending 3.0-liter Duramax diesel production



It appears that Chevrolet’s Silverado, its sibling GMC Sierra, and several other General Motors full-size trucks and SUVs continue to run out of product, and parts shortages are still the main reason.

In July, it was semiconductors, and even more so the global shortage of these valuable microchips, that caused production for the lion’s share of GM’s large-scale rigs to shut down. Now, again, a shortage of parts is the cause of the latest shutdown, which company officials maintain is only “temporary.”

However, it is important to note that this downtime was not mandatory for the vehicles themselves. Assembly activity at General’s engine plant in Flint, Mich., Halted only for the optional 3.0-liter Duramax LM2 I-6 diesel engine developing 277 horsepower and 460 lb-ft. for certain Chevrolet and GMC trucks and SUVs. models.

So, for now, the dealership order submission process is on hold for 2022 GM platforms that meet the criteria (3.0-liter Duramax diesel). When will the delay be over? Megan Soule, communications manager for Chevrolet trucks and full-size SUVs, said the company “will resume production as soon as possible.”

In addition to the Silverado and Sierra half-tons, the 2022 Chevrolet Tahoe and Suburban, Cadillac’s GMC Yukon and Escalade are also affected by the situation. Assembly of the 5.3 and 6.2 liter gasoline V8 engine continues as planned.
