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.

Chevrolet Silverado reportedly getting the GMC Sierra's MultiPro tailgate

GMC reinvented the pickup tailgate when it added a six-way option named MultiPro to the current-generation Sierra it introduced in 2019. It kept this clever feature to itself as a way to differentiate the Sierra from the Chevrolet Silverado, but a recent report claims it will begin sharing it in the not-too-distant future. Enthusiast website GM Authority learned from anonymous sources familiar with Chevrolet's product plans that the Silverado will soon receive its own version of the MultiPro tailgate. It will be called either MultiFlex or Multi-Flex, a name Chevrolet has already trademarked, and it was initially scheduled to make its debut for the 2021 model year. Its arrival might be delayed until the 2022 model year due to the coronavirus pandemic, however. Chevrolet's Silverado and GMC's Sierra are nearly identical under the sheet metal, so adding the latter's six-way tailgate to the former will be a relatively straightforward and cost-effective process. Interestingly, GM Authority wrote engineers could add a seventh function to the tailgate, though it didn't reveal what they have in store. It's also not sure whether both trucks will get the new feature, or if it will exclusively be offered on the Chevrolet. 2022 will bring major updates to the Silverado and the Sierra, potentially including — as we've previously reported — an independent rear suspension. Interior upgrades will allegedly be part of the mid-cycle changes, too, but we still don't know if the Silverado will receive the tough carbon fiber cargo box available in the Sierra. In the meantime, motorists in the market for a Sierra will temporarily have fewer options to choose from. GMC has asked its dealers to stop taking orders for the regular- and double-cab variants of the truck, according to a separate report from GM Authority. Putting the slower-selling regular- and double-cab trucks on hiatus will allow dealers to build up their inventory of crew-cabs, which sell far better and are in relatively short supply. These restrictions will remain in effect until the 2021 model year, which starts on September 14 for double- and crew-cab models and on September 21 for regular-cab trucks. All three body styles will be available in 2021. Related Video:

Aston Martin DBX and the craziest car redesigns | Autoblog Podcast #716

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor James Riswick. They chat about slumming it in the Aston Martin DBX, the brand's first SUV, which they didn't have terribly high expectations for yet utterly blew them away. Riswick in particular notes it's one of the best cars he's ever driven, describing it as a family GT car. They then switch to a very different family vehicle: the 2022 Kia Carnival, and the unique second-row seating arrangement we've dubbed the "Captain Kirk chair." Greg has also been driving the Chevrolet Tahoe Premier. They also chat about two of Riswick's recent features: the 20 craziest car redesigns of the past 20 years and the best cars for snow.  Autoblog Podcast #716 Get The Podcast Apple Podcasts – Subscribe to the Autoblog Podcast in iTunes Spotify – Subscribe to the Autoblog Podcast on Spotify RSS – Add the Autoblog Podcast feed to your RSS aggregator MP3 – Download the MP3 directly Rundown Cars we're driving Aston Martin DBX 2022 Kia Carnival 2022 Chevy Tahoe Features 20 craziest car redesigns of the last 20 years Best cars for snow Feedback Email – Podcast@Autoblog.com Review the show on Apple Podcasts Autoblog is now live on your smart speakers and voice assistants with the audio Autoblog Daily Digest.
