GM taps Honeywell's Quality Control System for Ultium battery plant

The Chevrolet Bolt recall has been so frustrating for General Motors that the automaker made an unexpected show of public hopelessness in saying it was "not confident" that LG — which produces the Bolt's batteries — could produce batteries without defects. Even though the remark came before investigation teams founds the source of the Bolt battery issue, it was even more strange considering GM and LG are still in bed together, the two having invested more than $2.3 billion in a 2.8-million-square-foot plant to make GM's Ultium batteries in Lordstown, Ohio. Now that GM has even more motivation to keep its Ultium batteries free of scandal, GM has tapped Honeywell for that company's Quality Control System at the Lordstown facility. The Honeywell QCS will monitor four of the production lines at the facility using "high-precision scanners and basis weight sensors." One of the parameters measured will be electrode coat weight, a key stat in battery performance. Another measurement and control company wrote, "Improving the electrode coating process is a significant part of the equation to delivering better quality and better performing cells – and coating uniformity is seen more and more as a critical requirement." Honeywell says it has more than 20 years of experience with lithium-ion technology, and the firm is already found throughout the green economy. A GM spokesman made sure to say that "the awarding of the Ultium contract to Honeywell has nothing to do with the Bolt recall." Yet in the Honeywell press release, a company director spoke words that could have come straight from GM, with, "Given the opportunity at hand, battery manufacturers such as Ultium Cells must be able to bring new solutions to market with confidence." The new Lordstown facility is scheduled to open in the first quarter of next year. It will employ more than 1,100 workers building the prime movers for coming EVs like the new Hummer and the Cadillaq Lyriq. Ideally, before then, GM will have found and fixed all of the Bolts with issues, and can begin its Ultium era under sunny skies. The automaker started accepting LG batteries again last week, the new batteries should begin reaching dealers around the same time Bolt production resumes on October 11.

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 announces 3 new recalls affecting 1.7M vehicles in North America [w/video]

Still embroiled in the ongoing ignition switch recall, General Motors announced today three more discrete recalls, affecting a grand total of 1,546,900 vehicles in the US. The Detroit News reports that some 1.7 million vehicles are affected overall in North America. The first and largest of the trio of new recalls concerns some 1.18-million Buick Enclave and GMC Acadia crossovers from the 2008-2013 model years, Chevrolet Traverse from 2009-2013 (pictured above) and Saturn Outlook vehicles from 2008-2010. All of the crossover utilities may have an issue with the wiring harness for their seat-mounted side airbags. Apparently, the vehicles are equipped with a Service Air Bag warning light that, if ignored, "will eventually result in the non-deployment of the side impact restraints." Those restraints include the side airbags, a front-center airbag if the vehicle is so equipped and seatbelt pretensioners. Dealers of affected vehicles will be instructed to remove driver and passenger side airbag wiring harness connectors, and then "splice and solder the wires together." The second recall affects 303,000 Chevrolet Express (pictured right) and GMC Savana vans from model years 2009-2014, and with gross vehicle weights under 10,000 pounds. Said vehicles do not comply with a head impact requirement for unrestrained occupants, and will need a reworking of the instrument panel material to be sent back on the road. It doesn't sound as though there's a quick fix for this one, as the GM press release states: "Unsold vehicles have been placed on a stop delivery until development of the solution has been completed and parts are available." Finally, the third recall affects 63,900 Cadillac XTS luxury sedans from model years 2013 and 2014. A brake booster pump may be susceptible to corrosion by way of the relay, potentially causing and electrical short, overheating, melting of plastic components and even engine fires. GM says it is aware of two engine fires in unsold XTS models and two cases of melted parts. Repairs for the issues affecting the XTS have not not mentioned by GM in the release. The Detroit News is also reporting that along with news of the triple-recall, GM is taking a $300-million credit to help pay for the repair costs, and to deal with the ongoing costs associated with the ignition switch recall. In an attempt to explain just what GM has been doing in the face of these very serious issues, newly minted CEO Mary Barra has addressed the issues in a new video.
