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.

'Killing a Duramax' Gale Banks YouTube series methodically tunes a diesel to death

Learning or perfecting a skill by watching YouTube videos is known as attending YouTube University. GM Authority picked up on one of the video site's more fascinating courses, hosted by Gale Banks; in a fair world, he should be referred to as Professor Banks when it comes to diesel engines and truck tuning. A few months after GM introduced the updated L5P 6.6-liter Duramax diesel V8 in the 2020 Chevrolet Silverado HD and GMC Sierra HD that ships with 454 horsepower and 910 pound-feet of torque, Banks decided he wanted to methodically tune the engine to death. The purpose of the resulting series, called "Killing a Duramax," is to push more power out of the engine in order to discover which parts break and when — or, as Banks puts it, force-feed the Duramax "until the crank hits the street and the heads hit the hood." With that knowledge, Banks can figure out all the weak points on his way to building what he calls a "Superturbo," that being a supercharged, twin-turbo race engine with more than 1,000 hp. What makes the series fascinating is Banks' knowledge, paired with the company's comprehensive iDash engine monitoring system that keeps tabs on a glut of parameters every step of the way. So for instance, you get Banks explaining the differences between inches of mercury and barometric pressure, how those are different from the water content of the air measured in grains, then showing those readouts on the iDash, then explaining in detail how they affect the air density in the Duramax system. The stock Borg-Warner variable turbo gets a lot of airtime — Banks accuses it of being "out to lunch" because he feels it's the weakest link on the engine. That turns into a turbo teardown and a deep explanation of performance pitfalls, such as when air pressure on the turbine begins to diverge from the boost pressure coming from the compressor. Banks says he can keep close tabs on where power's coming from, because the iDash monitors the horsepower contribution provided by the ambient air, the turbo, and the intercooler separately. The major changes so far are a stouter Precision 7675 turbo and TurboSmart wastegate (episode 5), a twin intake (episode 6), a custom liquid-cooled intercooler from a marine engine, a new GM oil cooler and synthetic oil (episode 10), and new injectors (episode 11).

2022 Detroit Auto Show Editors' Picks

As tends to be the case in this post-ish-pandemic world of auto shows, the North American International Auto Show was a strange one. It was at least mostly indoors and thus not at the mercy of Mother Nature. And unlike that first Chicago Show following the initial pandemic shutdown, this one was all assembled before the media arrived. Even with a much thinner show floor, the Detroit Auto Show still gave us a number of noteworthy reveals. Now, full disclosure, the rules for our Detroit picks were made a little more flexible, since some of these vehicles were revealed a little before the week of the show. But we still focused on vehicles that were making their show debut, and were actually present on the floor. Sadly, that means we had to leave out the Jeep Recon and Wagoneer S electric SUV concepts. Odds are, those would've made it into our list of the top five if they had actually been on display. Now, on to the winners. 2023 Jeep Wrangler Willys 4xe View 18 Photos 5. 2023 Jeep Wrangler Willys 4xe This was an easy one. While there's nothing so remarkable about the Willys that it makes this package a must-buy, it's nice to see another model available with the 4xe powertrain. Just one question, though: Where was the Recon? – Byron Hurd Chevrolet Blazer EV View 7 Photos 4. 2024 Chevy Blazer EV As a fan of the K5 and S-10 Blazer generations, I was a bit bemused when the current-gen crossover came out ... until I drove it and realized how good it actually is. Now that there's a Blazer EV incoming, I feel like I can become a true fan again. And there's a lot for fans to appreciate: FWD, RWD and AWD versions, and even a 557-horsepower SS variant. In a lineup of practical, Ultium-based Chevy utes, it's good to see an attainable product that enthusiasts can get behind — along the lines of Ford with its Mustang Mach-E — while we wait for an electric Corvette. — Senior Editor, Green, John Beltz Snyder 2023 Chrysler 300C View 28 Photos 3. 2023 Chrysler 300C In a poignant press conference with the Spirit of Detroit statue in the background, Chrysler sent its flagship 300 out properly with a 6.4-liter Hemi V8. Stellantis design chief Ralph Gilles articulated the car's successes — its many awards and sterling reviews from its early days — and the cover came off with a veritable 300C hot rod on display. One more time, the 300 is at full strength. To be clear, this isn't the 300S with an available 5.7-liter.
