GM pauses 3.0-liter turbodiesel production due to a supplier shortage

General Motors confirmed it has temporarily stopped taking orders for trucks and SUVs equipped with the 3.0-liter Duramax turbodiesel six-cylinder engine. It blamed the last-minute pause on a supplier-related shortage. Website TFL Truck first reported the news, and a representative from General Motors quickly confirmed it. The spokesperson explained the issue is due to a "temporary part shortage" and added that production will resume "as soon as possible," meaning the Duramax engine (which is called LM2 internally) is not going away permanently. Additional details are not available, so we don't know if the issue is related to the ongoing chip shortage. Rather than delay deliveries and create a backlog, General Motors is reportedly asking its dealers to encourage buyers who want a turbodiesel engine to instead select either the 5.3-liter V8 or the 6.2-liter V8, depending on the model selected. Both are gasoline-powered units. There's no word yet on when Duramax production will resume. The shortage affects several models, including Chevrolet's Tahoe, Suburban, and Silverado 1500 and GMC's variants of these trucks. Cadillac's Escalade is temporarily diesel-less as well. Heavy Duty variants of the Silverado and the Sierra are not affected because they're powered by a different Duramax engine with eight cylinders. Motorists seeking a full-size SUV powered by an efficient turbodiesel engine are temporarily out of options because the Tahoe/Yukon and the Suburban/Yukon XL had the segment to themselves. The Duramax was surprisingly popular, too: in May 2021, GM Authority reported that the turbodiesel straight-six represented 8% of Suburban sales and 6% of Tahoe sales. Installed in a rear-wheel-drive Tahoe, the engine returns 21 mpg in the city, 28 mpg on the highway, and 24 mpg in a combined cycle, figures that make the body-on-frame behemoth more efficient than the unibody, front-wheel-drive Chevrolet Blazer that's 20 inches shorter and approximately 1,700 pounds lighter.

GM now finishing and shipping pickups it had parked for lack of chips

DETROIT — General Motors is more than halfway through shipping newly-assembled pickups that it had parked due to a shortage of semiconductor chips, a top executive at the No. 1 U.S. automaker said on Friday. "We've made great progress," Steve Carlisle, GM's North American chief executive said at the Reuters Events Automotive Summit. "We're a bit better than halfway through that at the moment and our goal would be to clear out our '21 model years by the end of the year. We'll have a bit of a tail of '22 model years into the new year but not for too long." The global chip shortage has forced automakers like GM to idle production or in some cases mostly build vehicles and then park them until the necessary chips can be installed, allowing those vehicles to be then shipped to dealers. Last month, GM Chief Financial Officer Paul Jacobson cautioned that GM's third-quarter wholesale deliveries could be down by 200,000 vehicles because of chip shortages. He did not break out what share of that was trucks. To expedite transportation of newly-built vehicles to dealers, Carlisle said GM bought a number of car haulers to deliver them from factories or distribution centers. The Detroit automaker has also allowed dealers to pick the vehicles up themselves in some locations. Carlisle said new vehicle inventories have shrunk to below 20 days in the United States due to the supply chain disruptions, but the company wants to get that back up to 30 to 45 days with some getting to 60 days depending on the product line. GM sees sales of gasoline-powered vehicles being steady over the decade and real growth opportunity in electric vehicles and software, with one not undermining the other, he said.  

2025 GMC Terrain is redesigned with bolder style and big tech

The 2025 GMC Terrain is here, and it’s following in the footsteps of its Chevrolet Equinox cousin but bringing the traditional GMC twist to the party. Its fresh design is noticeable straight away with a new front end inspired by the GMC Canyon. The front hood is substantially higher than before giving it a more muscular look, and the same bulking is evident in its emphasized fenders. An optional painted roof gives it some flash – itÂ’s painted gray for black cars (pictured above) and black in every other case. Bigger wheels up to 20 inches in diameter are available on the Denali. And speaking of trims, there are now just three: Elevation, AT4 and Denali. For 2025, the Elevation is the only model that will be on sale. GMC says both the AT4 and Denali models will follow later for model year 2026, and you can see a preview of those in the group photo below. They each have their own grille designs, wheel options and unique styling cues. As youÂ’d expect from the AT4, it also features an off-road-tuned suspension, small lift (by 12 mm) all-terrain tires, underbody skid plates, recovery hooks and a special “terrain” drive mode. The Denali has its own pluses like “Smart Frequency Dampers” for a better ride, tons more standard luxury equipment and the 20-inch wheels. What is common across all trims is the powertrain. Every next-gen Terrain will be equipped with a 1.5-liter turbocharged four-cylinder paired with an eight-speed automatic transmission. ThatÂ’s the same powertrain as the new Equinox, and while GM has indicated it will move to more hybrid options, thereÂ’s no word on if the Terrain would be a candidate for that strategy. The 2025 model will be all-wheel drive exclusively, but GMC tells us youÂ’ll be able to select a front-drive version come the 2026 model year. If you want to tow, though, youÂ’ll need the AWD version that maxes out at 1,500 pounds. The 2025 TerrainÂ’s interior gets a massive overhaul thatÂ’ll remind you of other new GMC products with its tall portrait-oriented touchscreen. ThereÂ’s the 15-inch screen in the center thatÂ’s accompanied by an 11-inch digital cluster, of which both are standard equipment. It runs Android Automotive software that nets you Google Maps as the native navigation system and the Google Assistant for voice queries. Both wireless Apple CarPlay/Android Auto remain onboard, though, as GM promised would be the case for its gas-powered vehicles.
