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 considering new powertrain options for large SUVs

Aside from the new General Motors offerings, there's not a whole lot of action going on in the fullsize SUV segment. That doesn't seem to be stopping GM from pushing the envelope in the market as Automotive News is reporting that the automaker is looking to introduce some new powertrain options into the Chevy Tahoe (and Suburban), GMC Yukon (and Yukon XL) and the Cadillac Escalade - all have been redesigned for the 2015 model year.
Now, we already know that GM and Ford are collaborating on nine- and ten-speed transmissions for a broad range of applications (including the big SUVs), but this new report says that GM is also considering other options as a way to one-up the competition and, of course, to optimize fuel economy. AN quotes Jeff Luke, executive chief engineer for GM trucks, as saying that "interesting powertrain technologies" are coming including a return of a hybrid SUV and possibly even a diesel engine. Although it sounds like the latter could come down to how customers respond to the 2014 Jeep Grand Cherokee EcoDiesel.

GM recalls nearly 1 million vehicles for airbag defect

WASHINGTON — General Motors said on Friday it will recall nearly 1 million sport utility vehicles in the United States because the driver's airbag inflator may explode during deployment. The recall covers 994,763 Buick Enclave, Chevrolet Traverse, and GMC Acadia vehicles from the 2014 through 2017 model years with modules produced by ARC Automotive Inc. Dealers will replace the driver's airbag module. The National Highway Traffic Safety Administration said a driver in Michigan of a 2017 Chevrolet Traverse was in a crash in which the front-driver airbag inflator ruptured during deployment causing facial injuries. An April 25 inspection confirmed that the front driver airbag inflator ruptured in the vehicle. The National Highway Traffic Safety Administration (NHTSA) demanded the recall of 67 million air bag inflators because it believes there is a safety defect, but auto supplier ARC Automotive Inc rejected the U.S. regulator's request, documents released on Friday show. The auto safety agency said the inflators pose an unreasonable risk of death or injury. Even as ruptures mount, "ARC has not made a defect determination that would require a recall of this population," NHTSA said in its demand letter to the Tennessee-based company. "Air bag inflators that project metal fragments into vehicle occupants, rather than properly inflating the attached air bag, create an unreasonable risk of death and injury." GM said it was still investigating the issue with the assistance of a third-party engineering firm. "GM is taking this expanded field action out of an abundance of caution and with the safety of our customers as our highest priority," the Detroit automaker said. GM said it was aware of two prior ruptures of ARC-manufactured airbag inflators in 2015 Chevrolet Traverse vehicles, and GM conducted two earlier small recalls of about 3,000 ARC inflators. All three rupture events in Chevrolet Traverse vehicles involved the same inflator variant. ARC noted in a letter made public Friday that no root cause for those ruptures has been identified by ARC or GM. ARC said it was assessing the scope of GMÂ’s recall.  Government/Legal Recalls Buick Chevrolet GMC Safety Crossover SUV
