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.

Harsh words from senators over Chrysler's delay in reporting hack

The federal agency charged with protecting American motorists wants to know more about how hackers remotely commandeered and controlled a Jeep Cherokee. Hours after Fiat Chrysler Automobiles recalled 1.4 million cars affected by a flaw in their cellular connections, officials with the National Highway Traffic Safety Administration said Friday they'll further probe the defect by conducting a formal recall query investigation. "Opening this investigation will allow NHTSA to better assess the effectiveness of the remedy proposed," the agency said in a written statement. The remedy works, said Chris Valasek, one of the researchers who first discovered the security flaw. After testing for the vulnerability again Friday, he wrote on Twitter: "Looks like I can't get to @0xcharlie's Jeep from my house via my phone. Good job FCA/Sprint!" From his Pittsburgh home, Valasek had previously accessed and controlled co-worker Charlie Miller's Jeep along a St. Louis highway. Researchers have demonstrated remote hacks before, but the scope and severity of the Jeep vulnerability was unprecedented. The recall for a cyber threat was the first of its kind. Although a software patch and changes made by cellular provider Sprint appeared to fix the problem, news of the exploit and Chrysler's response brought a fresh round of consternation on Capitol Hill, where federal lawmakers had already expressed concerns about automotive cyber security. The Jeep hack elevated their concerns to a new level. "Cyber threats in cars are real and urgent, no figment of the imagination, as this huge recall demonstrates," said Sen. Richard Blumenthal (D-CT). "Incredibly, Chrysler delayed disclosing this chilling cyber-security danger egregiously and inexcusably, and strong sanctions are appropriate to send a message that other auto manufacturers will heed." Chrysler had known about the security gap since October, and Sen. Ed Markey (D-MA) wondered why it took the company so long to let customers know they were at risk. "Despite knowing about this security gap for nearly nine months, Chrysler is only now recalling 1.4 million vehicles to fix this vulnerability," he said. That's a potential pitfall for Chrysler, and something NHTSA will likely address in its investigation. Automakers are supposed to report safety-related defects to the agency within five days of discovery. But according to a chronology of events Chrysler submitted in its recall paperwork, it didn't inform NHTSA until July 15.

Chrysler says its 8-speed transmissions will save 700 million gallons

Chrysler Group's TorqueFlite eight-speed transmission could be earning some serious green bragging rights if the company's projections are correct. The recently widely proliferated automatic gearbox, which is now in more than a million vehicles around the world, is poised to save drivers an estimated 700+ million gallons of fuel over the vehicles' lifetimes (an expected cost savings of $2.5 billion). In addition, Chrysler expects a reduction in CO2 emissions by more than six million metric tons. According to Chrysler, and depending on the vehicle, the TorqueFlite can improve fuel economy. The TorqueFlite autobox features particularly close ratios from fifth to eighth gear (see the press release below for the specific numbers), and uses low-viscosity fluid that doesn't need to be replaced. Transmission software adapts to the driving situation to optimize efficiency based on driver behavior, temperature, grade, stability control, and longitudinal and lateral acceleration. The TorqueFlite is capable of handling a variety of duties. As evidenced by the wide range of vehicles Chrysler Group has seen fit to equip with the eight-speed transmission, the TorqueFlite is capable of handling a variety of duties. Since its 2012 introduction, the TorqueFlite has gone from performing cog-swapping duties in Dodge Charger and Chrysler 300 models equipped with the 3.6-liter Pentastar V6 to changing gears in vehicles such as the Pentastar- and Hemi-powered Dodge Durango, Jeep Grand Cherokee and even the Ram 1500 EcoDiesel. For the 2015 model year, the eight-speed is finding its way into even more vehicles with the addition of a third version. In addition to the American-made TorqueFlite 845RE and 8HP70, the new 8HP90 will be manufactured in Saarbrucken, Germany. The 8HP90 is designed for higher torque loads, making it ideal for high-performance vehicles like the 2015 Dodge Challenger SRT Hellcat. The already-in-use 8HP70 will expand its duties to be used in 2015 Hemi models such as the Dodge Charger, Challenger, and Challenger SRT8. You can see the list of those benchmarks in Chrysler's press release below.
