Hyundai, Kia recall 270,000 cold-weather state vehicles over rust

Hyundai has announced plans to recall 240,000 Sonata and Azera models registered in the northern United States over corrosion caused by the use of road salt. Exposure to the salt can cause rust to form (we know, basic chemistry here), and that the corrosion can change the alignment of the rear wheels, according to Reuters.
Sonatas from the 2006 to 2010 model years, built between March 1, 2005 and January 21, 2010, and Azeras from the 2006 to 2011 model years, built between September 27, 2005 and November 22, 2010, are covered only if they were registered in the following states: Connecticut, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, Wisconsin and Washington, DC. So basically, every state from the Midwest, to the central Atlantic coast, to New England. It is unclear exactly how many Sonatas or Azeras make up the 240,000 total number.
Hyundai is also recalling 20,300 of its 2013 Santa Fe Sports, while sister company Kia is recalling 9,345 2014 Sorentos. This second recall only covers Santa Fe Sport and Sorento models with the base, 2.4-liter engine and front-wheel drive. Apparently, the front axle driveshaft can develop cracks and separate.

Solid-state batteries: Why Toyota's plans could be a game-changer for EVs

Word out of Japan today is that Toyota is working on launching a new solid-state battery for electric vehicles that will put it solidly in the EV game by 2022. Which leads to a simple question: What is a solid-state battery, and why does it matter? Back in February, John Goodenough observed, "Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted." And risking a bad pun on his surname, he seemed to be implying that all of those characteristics weren't currently good enough in autos using lithium-ion batteries. This comment is relevant because Goodenough, professor at the Cockrell School of Engineering at the University of Texas at Austin - it so happens, he turns 95 today - is the co-inventor of the lithium-ion battery, the type of battery that is pretty much the mainstay of current electric vehicles. And he and a research fellow at U of T were announcing they'd developed a solid-state battery, one that has improved energy density (which means a car so equipped can drive further) and can be recharged more quickly and more often (a.k.a., "long cycle life") than a lithium-ion battery. (Did you ever notice that with time your iPhone keeps less of a charge than it did back when it was shiny and new? That's because it has a limited cycle life. Which is one thing when you're talking about a phone. And something else entirely when it involves a whole car.) What's more, there is reduced mass for a solid-state battery. And there isn't the same safety concern that exists with li-ion batteries vis-a- vis conflagration (which is why at airplane boarding gates they say they'll check your carryon as long as you remove all lithium-ion batteries). Lithium-ion batteries may be far more advanced than the lead-acid batteries that are under the hood of essentially every car that wasn't built in Fremont, Calif., but as is the case with those heavy black rectangles, li-ion batteries contain a liquid. In the lithium-ion battery, the liquid, the electrolyte, moves the lithium ions from the negative to the positive side (anode to cathode) of the battery. In a solid-state design, there is no liquid sloshing around, which also means that there's no liquid that would freeze at low operating temperatures. What Toyota is using for its solid-state battery is still unknown, as is the case for the solid-state batteries that Hyundai is reportedly working on for its EVs.

Hyundai recalls about 980,000 Sonatas for seat belt detachments

The Basics: Hyundai is recalling 977,778 Hyundai Sonatas and Sonata Hybrids for seat belts that could detach from their anchor pretensioners, which could lead to an injury. The recall affects 2010- cars including 2011-2014 standard Sonatas built from December 11, 2009 to May 29, 2014 and 2011-2015 Sonata Hybrids built from December 2, 2010 to January 9, 2015. The Problem: During manufacturing, some Sonatas may not have had the seat belt properly attached to the anchor pretensioner. According to NHTSA recall information, the seat belt is connected to the anchor after the latter has been installed, and it is possible that the seat belt didn't completely latch onto the anchor during assembly. If the seat belt was not properly attached, it can separate from the anchor during a collision, potentially leading to an injury. Injuries/Deaths: Hyundai has reported one injury to NHTSA. No deaths related to the recall have been reported. The Fix: Owners are asked to bring in their vehicles to dealerships to have the seat belt assembly inspected to make sure the belt is correctly latched. If not, the dealer will reattach it properly at no cost to the owner. If you own one: Hyundai will alert owners to the recall by mail starting April 7. Owners can also call Hyundai's customer service directly to ask about the recall at 1-855-371-9460. They can also enter their VINs at the NHTSA website to check if their car is included in the recall. Related Video:
