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.

2018 Kia Stinger GT AWD Review: A 1,400-mile grand tour in Kia's grand tourer

They call the 2018 Kia Stinger a GT. It's powerful and sleek with a low-slung seating position, quick steering and, even with all-wheel drive, a tail-happy nature. It looks killer in red. And with its V6-powered engine, the letters GT are even festooned upon its liftgate. Well, that's nice, but how does it actually deliver on the grand-tourer formula of rapid, comfortable and stylish transportation? Well, to find out, I put the Stinger GT to a grand-touring test. Starting in the western Rockies and the remote ski town of Crested Butte, Colo., my destination would be home in Portland, Ore. The Google-suggested way is 18 hours on mostly Interstates 70, 15 and 84. However, interstates are boring and are better suited to a perfectly capable but utterly soulless family transportation appliance. A proper grand tour should include two-lane highways and scenic detours, so that's exactly what I'd do. It would add hours and miles, but also, most hopefully, a vastly more memorable experience. Well, as my photos will attest, the scenery didn't disappoint. And, as you'll see in the videos, neither did the Stinger. Episode 1: Setting Off Episode 2: It's a hatchback! Crested Butte, Colo., to Moab, Utah Crested Butte is way off the beaten path, a charming mountain village deep in the western Colorado Rockies mostly free from the usual uber-commercial, Disney-like feel of ritzier, easier-accessed ski towns. Its main street thoroughfare, authentically Western rather than engineered to be so, is surrounded by scattered subdivisions and majestic mountains beyond. It had been buried in 9 feet of snow just a few weeks prior. The local citizenry didn't seem particularly bothered by that. Though most of that 9 feet had melted, the ground was still very much white, requiring the Stinger GT to shed its usual summer rubber in favor of Michelin Pilot Alpin PA4 winter tires. These are specifically intended for performance car applications like the Stinger, sacrificing just a smidge of icy traction in favor of superior handling and steering feel when on dry pavement. There's no need to delay the verdict here: after 1,400 miles, the Stinger felt just as generally compelling and dynamic on the Alpins as when I drove it last November in Southern California on summer tires. The other half of the Stinger's snow defense is the GT's optional all-wheel-drive system, which adds $2,000 to its price tag (as-tested $52,300).

The Kia Optima is now available as a plug-in hybrid

The Kia Optima gets electrified two ways for 2017. In addition to the conventional hybrid, there's a new plug-in version as well – makes sense, since the Optima's corporate sister, the Hyundai Sonata is offered with both options. The new Kia Optima Hybrid ditches the larger 2.4-liter internal combustion engine from the previous model in favor of a smaller 2.0, good for 154 horsepower, and mated to a six-speed automatic transmission that does away with the torque converter in favor of an electric clutch, with electric water and oil pumps to help optimize efficiency. Working in tandem with the 38-kW electric motor and juiced by a 1.62-kWh lithium-polymer battery pack, the powertrain delivers a total of 193 horsepower while targeting a 10 percent improvement in fuel efficiency over the previous Optima Hybrid. Not enough? Tew Optima PHEV that uses the same 2.0-liter four, but instead of 38 kW (51 hp), the plug-in's electric motor produces 50 kW (or 67 hp), and instead of 1.62 kWh, the PHEV's lithium-ion battery pack is rated exponentially higher at 9.8 kWh. It's said to travel for 600 miles before needing to stop, or up to 27 miles on electric power alone. And of course it can be recharged directly from the socket, taking less than nine hours on 120 volts and less than three on 240. If those powertrain components sound familiar to you, that's because they're identical to those offered in the Sonata Hybrid and Plug-In Hybrid from Kia's sister brand Hyundai. Only here they're packaged into a more angular, less curvy form and capped by a Kia badge and tiger-nose grille. Interested? There's plenty more to digest in the pair of press releases below.
