US expands probe into ZF-TRW airbag failure-to-deploy to 12.3 million vehicles

DETROIT — U.S. auto safety regulators have expanded an investigation into malfunctioning airbag controls to include 12.3 million vehicles because the bags may not inflate in a crash. The problem could be responsible for as many as eight deaths. Vehicles made by Toyota, Honda, Kia, Hyundai, Mitsubishi and Fiat Chrysler from the 2010 through 2019 model years are included in the probe, which was revealed Tuesday in documents posted by the National Highway Traffic Safety Administration. It involves airbag control units made by ZF-TRW that were installed in the vehicles. The control units can fail in a crash, possibly because of unwanted electrical signals produced by the crash itself that can disable an air bag control circuit housed in the passenger compartment, according to NHTSA documents. The electrical signals can damage the control circuit, the documents say. ZF, a German auto parts maker which acquired TRW Automotive in 2015, said in a statement that it's committed to safety and is cooperating with NHTSA and automakers in the investigation. The case is another in a long list of problems with auto industry airbags, including faulty and potentially deadly Takata airbag inflators. At least 24 people have been killed worldwide and more than 200 injured by the inflators, which can explode with too much force and hurl dangerous shrapnel into the passenger cabin. The inflators touched off the largest series of automotive recalls in U.S. history involving with as many as 70 million inflators to be recalled by the end of next year. About 100 million inflators are to be recalled worldwide. On April 19, NHTSA upgraded the ZF-TRW probe from a preliminary evaluation to an engineering analysis, which is a step closer toward seeking recalls. So far, only Hyundai and Kia and Fiat Chrysler have issued recalls in the case. Four deaths that may have been caused by the problem were reported in Hyundai-Kia vehicles and three in Fiat Chrysler automobiles. NHTSA opened an investigation in March of 2017 involving the TRW parts in Hyundais and Kias. The upgrade came after investigators found two recent serious crashes involving 2018 and 2019 Toyota Corollas in which the airbags did not inflate. One person was killed. Jason Levine, executive director of the Center for Auto Safety, a nonprofit consumer group, said the ZF-TRW case shows the auto industry thus far has learned very little from Takata.

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.

Senator pushes for up to life sentence for auto execs found to delay recalls

Democratic Senator Claire McCaskill (shown above) has had it with automotive execs stalling when it comes to recalls. The Missiourian has proposed a new bill, the Motor Vehicle and Highway Safety Enhancement Act, which aims to improve the automotive safety following the high-profile fiascos involving General Motors and Toyota. Aside from a doubling of the budget for the National Highway Traffic Safety Administration over the next six years and the removal of the $35-million limit for fining automakers, the plan includes a provision that would punish auto executives if it's discovered they knowingly delayed recalls. How will it punish them, you ask? Oh, you know, just life in prison. The bill "gives federal prosecutors greater discretion to bring criminal prosecutions for auto safety violations and increases the possible penalties, including up to life in prison for violations that result in death," McCaskill's office told The Detroit News. If a delayed recall led to serious injuries, meanwhile, execs could still face a 15-year stint behind bars. As for that change in the fine structure for automakers, the removal of the limit is complemented by a hefty increase in the per-vehicle fine, from $5,000 to $25,000. With this change, GM could have been on the hook for $55 billion (with a "b") in fines for its bumbling of the ignition switch recall, rather than just $35 million. The News says, though, that NHTSA has "wide discretion" in handing out the fines. Considering a $55-billion fine is enough to sink any automaker, it is unlikely that such a monumental sum would be handed out. Still, the potential threat of such a death sentence should be enough for any automaker to sit up and take notice. "With millions of Americans behind the wheel every day, and more than 33,000 killed on our roads each year, we've got to do more to keep our cars and the roads we drive them on safe," McCaskill said, according to The News. "Painful recent examples at Toyota and GM have shown us we also must make it easier to hold accountable those who jeopardize consumers' safety. For too long, auto safety resources have remained virtually stagnant while cars and the safety challenges they present have become more complex." What do you think? Do you agree with McCaskill's proposed bill? Should the punishments for automakers and execs be more or less harsh? Have your say in Comments. News Source: The Detroit NewsImage Credit: J.
