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 will recall more than 3.3 million vehicles in China for suspension defect

BEIJING (Reuters) - General Motors' joint venture in China, Shanghai GM, will recall more than 3.3 million Buick, Chevrolet and Cadillac vehicles stating Oct. 20 because of a defect with the suspension system, China's market regulator said on Saturday.

The recall includes cars produced between 2013 and 2018, the State Administration for Market Regulation said in a statement. GM will contact those affected and repair the vehicles free of charge, it said.

GM will expand Super Cruise to entire U.S. lineup after 2020

General Motors plans to bring its Super Cruise semi- autonomous highway driving technology to its entire U.S. lineup after it rolls it out to all Cadillac vehicles in 2020. Mark Reuss, GM's executive vice president for global product development, made the announcement at the Intelligent Transportation Society of America conference in Detroit. Automotive News reports he also announced plans to offer vehicle-to-everything (V2X) communication in a high-volume Cadillac crossover by 2023 — technology that will also eventually spread across the luxury brand's portfolio. Super Cruise is GM's semi-autonomous, lane-centering driving system that uses lidar mapping, GPS, cameras and sensors. The system offers hands-free driving on the highway, with an infrared camera and lights that track the driver's head position to make sure the driver is paying attention, ready to take over when needed, and not nodding off. If it senses the driver is unresponsive, it can bring the vehicle to a stop on the shoulder and activate OnStar. Super Cruise is already an option on the 2018 CT6 and standard on the Platinum trim model. You can read our First Drive review of the technology here. Meanwhile, Cadillac launched vehicle-to-vehicle technology in the 2017 CTS sedan, allowing equipped Cadillacs to share information regarding speed, direction and location at distances of up to 980 feet to help avoid collisions. By going one step further with V2X, Cadillac can tip off drivers to hazardous road conditions, the status of traffic lights, work zones and threats of crashes. It's the first major announcement from the luxury brand since the departure of former CEO Johan de Nysschen and his replacement by Steve Carlisle in April.
