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.

Kia showcasing Optima T-Hybrid concept in Paris [w/video]

At the Geneva Motor Show earlier this year, Kia showcased a new diesel hybrid powertrain. And at the rapidly approaching Paris Motor Show, it will present that new technology in the Optima sedan concept you see here.
Called the Kia Optima T-Hybrid, the concept mates a 1.7-liter diesel with both a turbocharger and electric supercharger to a small electric motor and a 48-volt lead-carbon battery. The mild hybrid setup allows it to travel in electric-only model at low speeds and at cruise, regenerating brake power to recharge the battery. Kia said it chose the lead-carbon battery pack over lithium-ion because it's easier to recycle and does not require active cooling.
Because the powertrain is still under development, Kia isn't saying what kind of fuel economy or emissions figures it gets in the Optima T-Hybrid concept, but it is targeting a "significant reduction" in emissions and fuel consumption, while delivering 15 to 20 percent more power. Check out the system in action in the video below.

Kia teases Cross GT concept for Chicago debut

Kia is headed to the Chicago Auto Show with a new concept. Details are scarce on the Cross GT at the moment, but we know the machine was penned as a luxury crossover. Larger than the current Sorento, we would wager there's three rows of seating on board. And while it's unclear whether or not Kia plans to bring something similar to market, we like what we see in the shadowy teaser above. The Cross GT seems to wear the company's "tiger nose" styling well, and the familiar D-pillar upkick ties the machine in nicely with the rest of the company's people-movers.
The 2013 Chicago Auto Show kicks off on February 7th, and should feature a number of interesting reveals. Those include the upcoming Toyota Tundra and what could be a special version of the Dodge Dart. Stay tuned for our live coverage on the show floor.
