A long list of trucks and SUVs are affected.
There's disappointing news for thousands of General Motors truck and SUV buyers. After GMC dealers received a message that production of the LM2 3.0-liter Duramax diesel inline-six engine had stopped, the American automaker said that "GM can confirm this is accurate due to a temporary part shortage. GM will resume production with the 3.0L Duramax diesel as soon as possible," in a message to The Fast Lane Truck. No additional information was provided.
Customers who may have recently placed an order for a vehicle equipped with the diesel are being advised to opt for the L84 5.3-liter V8 or the L87 6.2-liter V8 gasoline engines instead. Unfortunately, this won't suit buyers that demand the Duramax's capabilities, including its 460 lb-ft of torque and greater fuel efficiency. But the good news is that GM maintains (for now) that the engine option will return at a later date. This is in contrast with Ford's decision.
Last month, GM's crosstown rival decided to discontinue its Power Stroke diesel V6, introduced only in 2018.
At the time, it offered best-in-class 250 hp and 440 lb-ft of twist and returned an EPA-estimated 30 mpg highway rating. Buyers also benefit from up to 11,400 pounds of towing and 2,020 of payload capacity. The F-150's sole oil burner option was ultimately dropped likely because there were simply too many engine options. Not including the all-new F-150 Lightning EV, there are presently six powerplants offered to buyers, including the acclaimed PowerBoost hybrid.
Neither GM nor Ford has updated their official websites as both diesel engines remain listed as available to order, though we expect this will change shortly.
