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.

Nissan Leaf sales double Chevy Volt to close out winning 2014

To close out the year, sales of the two most-popular plug-in vehicles in the US kept going in the direction that they had been all year. The Chevy Volt dropped and the Nissan Leaf had another record month. Sound familiar? The Volt sold 1,490 units in December, a year-to-year drop of 37.7 percent. For all of 2014, Volt sales were down 18.6 percent to just 18,805 (from 23,094 in 2013). On the Nissan side of the ledger, the Leaf sold 3,102 units, up 22.7 percent from the 2,529 sold in December 2013. For the year, Nissan sold 30,200 Leafs, up 33.6 percent from the 22,610 sold in 2013. A few other things to note: For every month in 2014, the Leaf sold more than it did for the same month in 2013. For the Volt, this was only true for three months (April, May and July). Funnily enough, the Volt sold exactly 1,478 units in both March 2013 and 2014. The Volt's 2014 total was lower than both 2013 and 2012, while the Leaf had its best year ever. There were three months in 2014 when people bought at least twice as many Leafs than bought a Volt (September, November, December). The Leaf outsold the Volt every month in 2014. The closest gap was 215 units, in February. The biggest was 1,612, in December. As you've most likely seen, GM is still busy teasing the new Volt, which will make its official debut at the Detroit Auto Show next week. We'll have a more in-depth green car sales post up soon. <iframe embedded="true" "="" scrolling="no" src="https://docs.google.com/spreadsheets/d/1oIuH75vaSHaaplD4x6gLsYjSsiN4oGmez1T63eaYdhY/pubhtml?widget=true&headers=false" height="430"> Nissan celebrates 30,000 leaf sales in 2014, best year ever for sales of any plug-in vehicle NASHVILLE, Tenn. (Jan. 5, 2015) – Nissan, the world leader in electric vehicle sales, shattered yet another sales record with 30,200 LEAF vehicles sold in 2014, which is the first time any plug-in has sold more than 30,000 units in a single year. "Now in its fifth model year, Nissan LEAF is more popular than ever and continues to bring new buyers to Nissan," said Brendan Jones, director, Nissan Electric Vehicle Sales and Infrastructure. "From the beginning our vision was to bring electric vehicles to the mass market in a practical and fun-to-drive package, which is what makes Nissan LEAF the best-selling electric car in the world." Last month, Nissan sold 3,102 all-electric LEAFs, up 22.7 percent from the prior year and a December record.

GM recalling 686k Lambda-platform models for hatch repair

General Motors is recalling 686,287 units of its Lambda platform crossovers. On models equipped with a power rear hatch the system can potentially fail. This campaign includes the 2008-2012 Buick Enclave, 2009-2012 Chevrolet Traverse, 2007-2012 GMC Acadia, and 2007-2010 Saturn Outlook. According to GM's documents to the National Highway Traffic Safety Administration (as a PDF), dirt can get into a portion of the strut that holds up the hatch and cause the part to prematurely fail. There's a redundancy in place called the Prop Rod Recovery system that's designed to shut the liftgate if there's a malfunction. However, if the breakdown happens too quickly after the hatch is opened the prop rod might not work the way it's supposed to. If someone were in the way of the falling liftgate, they could be hurt. For the repair, dealers will update the software for the power liftgate actuator motor control unit to prevent the hatch from closing so quickly. They'll also check the operation of the system afterward.

The affected vehicles, equipped with the power liftgate option, have gas struts that hold the power liftgate up when open. These struts may prematurely wear and the open liftgate may suddenly fall. CONSEQUENCE: If the open liftgate unexpectedly falls, it may strike a person, increasing their risk of injury. REMEDY: GM will notify owners, and dealers will update the software for the power liftgate actuator motor control unit so that the motor will prevent the rapid closing of the lift gate, free of charge. The manufacturer has not yet provided a notification schedule.
