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 recalls 6,071 more Velosters over shattering sunroofs

Back in December, Hyundai issued a recall affecting some 13,500 Veloster hatchbacks because their optional panoramic sunroofs could possibly shatter while the vehicle is in motion. Now, an expansion of that recall has been announced, with an additional 6,071 units of the 2012 model year hatchback figuring in to the problem.
The original recall covered cars built between November 1, 2011 and April 17, 2012, but this expansion concerns vehicles built from July 4, 2011 to October 31, 2011. Just like before, the official National Highway Traffic Safety Administration bulletin states that these vehicles may be fitted with sunroofs that were inadvertently weakened during installation, and thus, can possibly break while the vehicle is in motion.
This second sunroof recall is expected to kick off next month. Dealers will inspect the sunroofs in these affected vehicles and will replace the whole assembly if necessary, free of charge. Scroll down to read the full NHTSA report.

Hyundai and Kia introduce new predictive transmission tech

Hyundai and Kia have announced that the two have developed a new transmission control system that optimizes shift logic to both improve efficiency and reduce "gear hunting." The system utilizes real-time traffic data, built-in 3D navigation and the same sensors that feed the cars' advanced safety and driver assist tech to proactively choose the right gear — even neutral in some cases — to reduce both fuel consumption and wear-and-tear. The Korean sister brands call it the "Information Communication Technology Connected Shift System," or "ICT" for short, and Hyundai says it delivers not just improved frugality, but a better all-around driving experience. ICT programming allows the transmission control unit to collect and interpret traffic, camera, sensor, navigation route, elevation and topographical data.  "Using all of these inputs, the TCU predicts the optimal shift scenario for real-time driving situations through an artificial intelligence algorithm and shifts the gears accordingly," the announcement said. "For example, when a relatively long slow down is expected and radar detects no speed irregularities with the car ahead, the transmission clutch temporarily switches to neutral mode to improve fuel efficiency." While this sounds like a primarily green play, there are quality-of-life improvements too. For example, ICT can also optimize gear selection and shift points for safer highway merges, effectively implementing the equivalent of a "Sport Mode" driving profile when a little extra punch is called for.  Hyundai says the resulting decrease in shifts was significant; in some test scenarios, such as roads with lots of curves, the number of shifts executed by the transmission was reduced by almost half. As an added bonus, these vehicles also utilized their brakes less often (11%), which would reduce wear (and accompanying maintenance costs) over time.  ICT is somewhat future-proof, too, as it was developed to incorporate vehicle-to-vehicle (V2V) data should such networks improve down the line.  The announcement did not say when the new tech would reach customers, committing only to introducing the technology "on future vehicles." If we're betting, the smart money says it will probably on a new Genesis model and trickle down from there. Related Video:
