GM investing $2 billion in Tennessee plant to build Cadillac Lyriq, other EVs

DETROIT — General Motors said on Tuesday it will invest $2 billion to convert its Spring Hill, Tennessee, factory to produce electric vehicles, starting with the new Cadillac Lyriq, alongside existing combustion-engine Cadillacs. Spring Hill will be GM's third U.S. electric vehicle factory, along with existing plants in Detroit and Orion Township, Michigan. The Tennessee plant was built in 1990 as the exclusive source for GM's now-defunct Saturn brand. The Cadillac Lyriq crossover is slated to go into production in Spring Hill in late 2022, according to AutoForecast Solutions (AFS), which tracks industry production plans. AFS said it expects some electric vehicle production will be announced at a later date for a factory in Mexico. Among additional investments, GM on Tuesday said it will spend $32 million at its truck plant in Flint, Michigan, to increase production of the Chevrolet Silverado and GMC Sierra heavy-duty pickups. GM will spend $100 million to shift production of the redesigned GMC Acadia crossover from Spring Hill to a plant near Lansing, Michigan. Spring Hill will continue to build the gas-engine Cadillac XT5 and XT6 crossovers. The plant also will build other future electric vehicles in addition to the Lyriq. The automaker's plans for investing in U.S. factories comes with two weeks left in the U.S. presidential election campaign. President Donald Trump and Democratic rival Joe Biden are competing for support from auto workers in Midwestern swing states. GM Chief Executive Mary Barra has outlined plans to invest $20 billion by 2025 in new electric vehicles and battery technology. The automaker is spending $2.2 billion to overhaul and retool its Detroit-Hamtramck factory to build a GMC Hummer EV electric pickup truck in late 2021, followed by an automated robotaxi and other electric vehicles. GM builds its electric Chevrolet Bolt at a large assembly plant north of Detroit.

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 recalling Silverado and Sierra HD diesel pickups over fuel gauge follies

General Motors is recalling 9,733 of its heavy-duty twins over concerns with their 6.6-liter diesel engines and dual fuel tanks. The recall covers some Chevrolet Silverado HD and GMC Sierra HD pickups from model years 2012 and 2013, although the exact dates that the recalled trucks were built isn't specified. There's also no mention of how many models come from Chevrolet and how many are from GMC.
The problem rests with the transfer pump responsible for moving fuel from the rear tank to the front tank - it could fail, resulting in an inaccurate fuel gauge. It hardly requires explaining, but a faulty fuel gauge could leave drivers in a situation where they run out of diesel.
GM will begin notifying customers of affected vehicles, who will be asked to report to their dealers for a free replacement transfer pump.
