Are old airbags killers?

Takata airbags may not be the only ones with some very serious problems. A new report from TheDetroitBureau.com claims that the National Highway Traffic Safety Administration has opened its second investigation into bad airbag inflators, and this time, they aren't from Takata. The focus of this latest case is on the airbag inflators in some 500,000 older Chrysler Town and Country minivans and Kia Optima sedans, all of which come from ARC Automotive. While the Takata case looks at problems stemming from the engineering and production process, the ARC investigation focuses on the age of the inflators. As TDB explains, airbag inflators are essentially what the military refers to as shaped charges, sort of like Claymores (for fans of the Call of Duty series). In combat, they blow up in a specific direction, protecting those behind the explosion, although in the case of airbags, the explosion "[creates] a precise rush of hot gases" that inflate the bags. NHTSA's worry is that with the increased average age of today's vehicles, years and years of being bounced, jolted, and shaken about and exposed to often-radical temperature changes have altered the nature of the explosives in these vehicles, causing too big of an explosion. "It may be a reasonable assumption that as these things age they deteriorate." – Analyst George Peterson "It may be a reasonable assumption that as these things age they deteriorate," analyst George Peterson told TheDetroitBureau.com. NHTSA boss Mark Rosekind backed up aging angle. "Cars are lasting on the road a lot longer than ever before," Rosekind told TDB, adding that seals could start breaking down. "Is aging now an issue? That's part of the investigation going on." NHTSA has only identified two "incidents" so far, although according to Center for Auto Safety Director Clarence Ditlow, there's genuine concern that there could be additional unidentified cases. "Could we have missed more? That could be the case," Ditlow told TDB, citing the misidentified deaths in the Takata investigation. Ditlow was quick to point out that, even in older vehicles, airbags are much more likely to protect than harm. "No one is saying you should disable your airbags," the safety advocate told TDB. "You're far more likely to be helped than hurt by one if they go off." At least one automaker, meanwhile, has already been advised of the investigation by NHTSA and is checking its airbags.

Hyundai and Kia set aside $412 million for false mileage claims

We still don't know how the whole fuel economy ratings debacle is going to play out for Hyundai and Kia, but both automakers are preparing to make good on their promises to reimburse vehicle owners for lower-than-promised mileage figures. According to Automotive News, Hyundai and Kia have set aside a combined total of $412 million ($225 million for Hyundai and $187 million for Kia) as compensation, which will be sent out on a case-by-case basis via debit cards depending on the vehicle and the mileage driven.
Announced back in November, the exaggerated miles per gallon claims affect around 900,000 Kia and Hyundai products produced for the 2011 through 2013 model years sold in the US and Canada. This whole deal has had plenty of action ranging from suspected whistleblowing from a rival US automaker and even insider trading, but it has probably been most frustrating for vehicle owners who, in most cases, saw their vehicles' city and highway ratings drop between one and three digits.

A closer look at the Kia GT4 Stinger Concept

When we named the Kia GT4 Stinger Concept as our top debut at the 2014 Detroit Auto Show, our comments section had, let's call it, a tantrum. People were not pleased. Debuting alongside hugely significant production cars like the Chevrolet Corvette Z06, Ford Mustang, Ford F-150, Lexus RC F, BMW M3/M4 and Chrysler 200 (not to mention great concepts like the Toyota FT-1, Infiniti Q50 Eau Rouge and Volvo Concept XC Coupe), what business did a tiny, turbocharged, rear-drive Kia concept car have winning the prize as the best of Detroit?
Well, as it turns out, it has every right to be there. Our own Michael Harley sat down with the head of US design for Kia, Tom Kearn, to discuss the GT4 Stinger and find out just what the brand was thinking when it decided to create such an enthusiast-oriented concept. The interview gives a great insight into the car and its design, while Harley goes into some detail at the end of the video about why the GT4 was the Autoblog Editors' Choice of the 2014 Detroit Auto Show.
