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.

GMC caught using Rivian R1T image for Sierra Denali EV Photoshop

The rise of electric start-ups have many legacy automakers checking their rear view mirrors as they scramble to join the EV party. Most wouldn't like to admit it publicly, but we know that at least some folks at General Motors are keeping an eye on Rivian. That's because a recent post on social media account by the General Motors design department appears to have used an image of the Rivian R1T, but heavily photoshopped. The post was intended as a peek of the GMC Sierra Denali EV's rear view. Eagle-eyed observers like AllCarNews soon noticed many familiar elements to the rendering, including the wheels and tires, mirrors and doors. Even the backgrounds are identical, including some leaves that the truck is kicking up. This content is hosted by a third party. To view it, please update your privacy preferences. Manage Settings. Seen side by side, the two pickups' similarities don't end there. The Sierra EV is wider, but the cab's rear pillars and glass look the same as the Rivian's, just stretched horizontally. The rear bumper and its license plate cutout and reflectors on either side look a bit too close for comfort as well.  The post as since been deleted. A GM spokesperson explained the situation to The Drive, "The GM Design Instagram channel is meant to give followers an inside look at the process of designing new products and the creative teams behind it. Often, these posts use sketches made for internal studio use during design development. The sketch in question was intended for internal use only, and was posted without the necessary approval. It has been removed from the GM Design Instagram page." Automakers often use products from the competition as benchmarks or design inspiration. Designers sometimes use existing images as a starting point as well, in order to quickly get an idea down "on paper". They just tend to do it in private. A juggernaut like GM using an image from an upstart like Rivian is embarrassing for the General, but surely an ego boost for the EV brand.  When dealing with an up-and-comer, perhaps it's best to take a page from Mad Men's Don Draper. In season four of the advertising drama, a newspaper calls the hot shot exec for a quote, after a young rival publicly says he's gunning for Draper. Draper knows exactly who the reporter is talking about but when asked for comment says, "Never heard of him." Related Video This content is hosted by a third party.

GM opens official investigation into C8 Corvette transmission leaks

In March 2020, a month after Chevrolet began customer deliveries of the 2020 C8 Corvette, a GM dealer technician created a Reddit thread about a leaking gearbox in a Corvette with 32 miles. That car hadn't even been sold yet. Since then, as a search of "C8 Corvette transmission leak" shows, it's been tales of woe for some owners. Something in the Tremec TR-9080 transaxle in the back of the mid-engined Corvette doesn't work as it should, the fault able to cause codes that the transmission needs service, or that the driver needs to shift to park. In some cases, the battery would die because of follow-on issues after the initial transmission code, that code preventing the car from powering down. As Autoevolution reports, GM filed paperwork with the National Highway Traffic Safety Administration in August to look into what's going on. Between forum threads and GM's investigation document, there are several issues mentioned. The most common appears to be the dual-clutch transmission leaking fluid due to gasket failures like the one suffered by one owner at 858 miles, and another for an owner currently enduring a second leaking transmission. The Midengined Corvette Forum reported that Chevy engineers redesigned the TR-9080 pan, fitting Corvettes with the new unit at some point in the 2021 model year. The original pan was stamped steel unit affixed to the engine with two studs and 13 bolts, plus "reinforcement plates." The updated pan is said to be a cast aluminum unit affixed with two studs and 17 bolts, omits the reinforcement plates, and gets a new machined new groove around its edge to seat the gasket seal. The GM paperwork now at the NHTSA mentions a P1789 code, and says one reason for it could be "debris on the park position sensor magnet causing an incorrect position reading to the TCM." This might be caused by another issue mentioned in forums, which is clogged transmission filters. GM gives instructions for returning transmission filters to the company, and a poster on one forum said the Corvette tech at the dealer where he bought his Corvette told him the automaker "requires every used transmission filter to be returned to GM."  Whatever's going on, the problems haven't stopped, and they go beyond the P1789 code. Over the weekend, a 2022 Corvette owner posted on Corvette Forums that he got a check engine light on his car after just 850 miles.
