Fingers point to dragged-out NHTSA investigation after second death by ARC airbag inflator

Safety advocates have increased criticism of the federal government's National Highway Traffic Safety Administration after an exploding airbag inflator that's been under investigation for more than six years killed a second person.  On Wednesday, NHTSA posted recall documents filed by General Motors that revealed the second death, the driver of a 2015 Chevrolet Traverse SUV with an inflator made by Tennessee company ARC blew apart, spewing shrapnel. No details were given about where and when the death occurred. NHTSA has said that ARC Automotive of Knoxville has manufactured about 8 million inflators used nationwide in vehicles made by General Motors, Fiat Chrysler (now Stellantis), Kia and Hyundai. “NHTSA should have been all over this along time ago,” said Rosemary Shahan, president of California-based Consumers for Auto Reliability and Safety. “There's just no denying that itÂ’s a (safety) defect.” NHTSA, the agency charged with with keeping America's automobiles and roads safe, began investigating ARC inflators in July of 2015 after two people were injured by flying shrapnel. The investigation became more urgent in 2016, when a Canadian woman driving an older Hyundai Elantra was killed by metal airbag fragments. Public records show only a little progress on the probe. In April, the agency posted a memo in saying it was reviewing volumes of information it received from ARC. Safety advocates such as Shahan say that the dragged-out investigation is an example of the deadly consequences that can result from an understaffed and underfunded agency. The second death should not have happened, Shahan said, and vehicles with faulty ARC inflators should have been recalled faster. The agency, Shahan said, is “grossly underfunded," but it still should have sought recalls of the ARC inflators. She said historically NHTSA has taken little action during Republican administrations but has ramped up safety efforts when Democrats control the White House. Messages were left Wednesday by the Associated Press seeking comment from NHTSA and ARC. At this time, relatively few vehicles are effected. The GM recall covers only 550 Chevy Traverse SUVs from the 2013 through 2017 model years, as well as Buick Enclave SUVs from 2008 through 2017. The automaker said in a statement that the faulty front driver's airbag inflators were either installed at the factory or in replacement airbag modules.

2022 Chevy Suburban, Tahoe, GMC Yukon, Cadillac Escalade up another $1,600

The 2022 Chevrolet Tahoe and Suburban, the 2022 GMC Yukon and the 2022 Cadillac Escalade have all gone up by $1,600. The GM profit and loss department added $1,500 to the MSRP for each of the full-sized SUVs and $100 to their destination charges, that destination fee now $1,795 for each vehicle. It's not an inconsequential bump; however, considering where the trucks were priced at launch, and everything that's happened since, the latest retail prices don't seem that bad. Take the Suburban — in February 2020, Chevrolet practically carried over pricing for the truck with a revamped interior and independent rear suspension, starting it at $50,295 after destination. After this latest increase, the 2022 Tahoe LS in two-wheel drive costs $55,590, after destination.  The delta between the 2021 Suburban at launch in March 2020 and the current model is a little grander compared to the Tahoe, like the SUV itself. Back then, it started at $52,295, the same price as the outgoing model. After this third price increase in the past year, the 2022 Suburban LS in 2WD starts at $61,290 after destination. GM Authority says the 2023 Tahoe and Suburban are reportedly headed down production lines in the middle of July. The biggest addition to both models will be the availability of Super Cruise, which is already available on the sister SUV, the Cadillac Escalade. The hands-free driving assistance feature can only be optioned on the Premier and High Country trims. It costs $2,500 to put Super Cruise on the Escalade. GM hasn't divulged the feature's price yet for the Chevy twins; that's likely to come when the automaker announces 2023 Tahoe and Suburban MSRPs, so beware of more potential price increases. After that, there's a heavy refresh planned for the 2024 model year, including a new instrument panel design that looks like it replaces the current gauge cluster with a large, freestanding screen.  The Yukon's entry-level price goes up to $57,590 for the SLE trim turning the rear axle.   The Cadillac Escalade's second MSRP bump takes it to $81,235 for the Luxury 600 trim in 2WD, and $84,235 for the extended ESV model in the same trim. The price creep hasn't stopped Escalades from pulling off dealer lots almost as soon as they're delivered, sales for the first quarter of the year totaling 10,505 units, trouncing domestic and foreign competition.

GM exploring ways to raise half-ton Duramax diesel tow rating

Lots of truck owners cheered when GM announced fuel economy numbers for the 2020 Chevrolet Silverado with the 3.0-liter Duramax diesel inline-six. Even after Ram let loose its EPA mileage ratings for the 2020 Ram 1500 EcoDiesel, the Chevy oil-burner still took the trophy. The victory was years in the making, GM engineers spending an entire four-year development cycle refining the LM2 Duramax to increase mileage. The tradeoff, as well all know by now, is towing; the Duramax in half-ton duty pulls a maximum 9,300 pounds in the Silverado. Rivals across town can do more, the Ford F-150 PowerStroke rated at 11,500, the Ram 1500 EcoDiesel game to pull 12,560. GM engineer John Barta told Muscle Cars & Trucks that more hauling chops could be on the way, explaining, "We’re actually looking at upgrading some of the materials around (the engine bay) to see if we can maybe raise our tow rating." Engine bay materials are at issue due to thermal complexities underhood. John Barta, GM's assistant chief engineer of diesel engine controls, said the Duramax's inline-six configuration allowed engineers to get emissions hardware like the combined selective catalytic reduction, diesel oxidation catalysts, and diesel particulate filter unit closer to the engine, where it heats up quicker, getting emissions down quicker. But that filter puts another heat source in those confines, enforcing a cap on the tow rating to keep the engine and other systems from overheating. "If you look under the hood," he said, "youÂ’ll see a significant amount of silver ‘moon tapeÂ’ around to make sure things arenÂ’t getting overheatedÂ… if we were to go up in higher towing, which we can, we start impacting the possibility of deteriorating some of the components.” There isn't much space for more grille, so swapping for a better grade of "moon tape" or a different kind of material could reduce engine bay heat, extracting a higher tow rating in the process.  It's important to note a point Barta's been making for months about the Duramax figures, though. "Even though itÂ’s nice to brag about big numbers, in reality, light duty customers are not towing that large with their trucks," and, "We do know that (95 percent) of our light duty customers donÂ’t tow over 9,000 pounds." On our First Drive of the 2020 Silverado diesel we called out the tow rating, but emphasized that the Chevy and GMC have more important challenges to overcome.
