The 2018 Kia Rio makes a quiet debut in New York

While the 2017 New York Auto Show might be dominated by another variant of the Dodge Challenger, the new 2018 Kia Rio sedan proves that the show isn't all about horsepower and quarter-mile times. We saw the latest iteration of the littlest Kia last fall in Paris, but we all know how much America loves sedans, so the Korean automaker saved the four-door debut for the US. The Rio gets a ground-up redesign for what will be its fourth generation. The design predictably looks like a shrunken version of the midsize Optima. Its handsome, if not exactly groundbreaking. All Rios ride on 15-inch wheels. Although they provide plenty of sidewall to soften the ride, they look just a little too small for the car. Both the sedan and five-door models are slightly longer than the previous models, meaning there's a bit of extra leg and trunk space than before. Inside, like the current Optima, expect a stark improvement over the previous generation when it comes to fit, finish, and interior materials. From the A pillar forward, the Rio sedan is essentially the same as the five-door. Notably for the segment, top-trim Rios have a touchscreen infotainment system with Apple CarPlay and Android Auto. Power comes solely from a 130 horsepower 1.6-liter inline four, a decent amount of power for this class. Drivers have the option of either a six-speed manual or six-speed automatic. Fuel economy numbers haven't been announced, but expect it to meet or exceed the previous model's rating of 27 city and 36 highway. The sedan and five-door models are set to go on sale later this year. Related Video:

NHTSA opens probe into 3 million Kia, Hyundai vehicles for fire risks

The National Highway Traffic Safety Administration said on Monday it would open a new safety defect investigation into three million Hyundai and Kia vehicles for fires not caused by crashes. The investigation is in response to a petition seeking a probe by the Center for Auto Safety. The auto safety agency since 2007 has been investigating some Hyundai and Kia vehicles for fire risks. The South Korean automakers have recalled more than 2.3 million vehicles since 2015 to address various engine fire risks. Hyundai did not immediately comment, while Kia did not immediately respond to a request for comment. NHTSA said the decision to initiate the additional safety defect probe was based on its analysis of information received from multiple manufacturers, consumer complaints and other sources. Last month, Connecticut Attorney General William Tong said a group of U.S. states is investigating Hyundai and Kia for potential unfair and deceptive acts related to reports of hundreds of vehicle fires. In November, Reuters reported that federal prosecutors had launched a criminal investigation into Hyundai and Kia to determine if vehicle recalls linked to engine defects had been conducted properly. Reuters reported in January that the companies would offer software upgrades for 3.7 million vehicles not being recalled. A South Korean whistleblower in 2016 reported concerns to NHTSA, which has been probing the timeliness of three U.S. recalls and whether they covered enough vehicles. In 2015, Hyundai recalled 470,000 U.S. Sonata sedans, saying engine failure would result in a vehicle stall, increasing the risk of a crash. At the time, Kia did not recall its vehicles, which share the same "Theta II" engines. In March 2017, Hyundai expanded its original U.S. recall to 572,000 Sonata and Santa Fe Sport vehicles with those Theta II engines, citing the same issue involving manufacturing debris. On the same day, Kia also recalled 618,000 Optima, Sorento and Sportage vehicles, all of which use the same engine.Reporting by David Shepardson.

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.
