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.

10 of 18 midsize SUVs earn 'good' IIHS side impact safety rating

It's not terribly surprising that midsize SUVs earned better safety ratings than small SUVs in the latest side-impact tests performed by the Insurance Institute for Highway Safety (IIHS). Just how much better they scored, on the other hand, certainly raises an eyebrow. Ten out of 18 midsize SUVs earned the highest rating of 'good' in the stringent new test, altered for vehicles starting with the 2020 model year with a heavier barrier (4,200 pounds) that moves at a higher speed (37 miles per hour) and is fitted with a hard honeycomb frontal structure. By way of contrast, just one out of of 20 small SUVs earned a 'good' score.  SUVs that receiving 'good' scores were the Ford Explorer, Infiniti QX60, Lincoln Aviator, Mazda CX-9, Nissan Pathfinder, Subaru Ascent, Toyota Highlander, Volkswagen Atlas, Volkswagen Atlas Cross Sport and Volkswagen ID.4. For EV fans, it's worth noting the ID.4 was the only electric vehicle included in the test. The Buick Enclave and Chevrolet Traverse scraped away with 'acceptable' ratings while the Honda Passport, Honda Pilot, Hyundai Palisade, Jeep Wrangler 4-door, Kia Telluride and Nissan Murano were deemed merely 'marginal' in the tough new test. Only two models — the Mazda CX-9 and Volkswagen ID.4 — earned a "Good" rating in every test category.  Interestingly, the Jeep Wrangler would have scored a 'good' rating if it were equipped with side airbags for the rear seating positions. It would likely be an engineering challenge to equip its removable top and/or doors with airbags, but the lack of that safety feature allowed the head of the rear passenger dummy to hit the vertical support of the top. Otherwise, the Wrangler scored good ratings across the board. The new Ford Bronco, which makes more allowances for side-impact safety, has not yet been tested.  The popular Hyundai Palisade and Kia Telluride SUVs stand out in the test with 'poor' ratings for driver pelvis injuries. The Nissan Murano, a vehicle last redesigned for the 2015 model year, was the only vehicle tested that received a 'poor' rating for its structure and safety cage. Videos of the tests of 12 of these 18 SUVs can be found on the IIHS' YouTube page.

2017 Kia Cadenza First Drive

"Garbanzo? Costanza? Credenza?" I can't tell if the guy at the bakery is trying to be funny or if he's genuinely forgetting the name of the car – I've told him twice; it's the 2017 Kia Cadenza. But you know, maybe the miscommunication is just fine. Like the Cadenza itself. It's fine. You shouldn't read that negatively. Every now and then in this job, you drive a car and simply come away thinking, "it was fine." And if you're building a car in this particular segment, that's practically the response you hope to elicit. A comfortable jack-of-all-trades at a price that isn't going to bankrupt the owner. Consider the Cadenza's competition: Toyota Avalon, Nissan Maxima, Chevrolet Impala, Buick LaCrosse. These aren't groundbreaking luxury vehicles, masters of utility or fuel economy, or Nurburgring-smashing sports sedans; they're... fine. You almost feel bad saying it – from a very reasonable angle it's a great segment, populated with cars offering a lot of the same equipment and a little more bang for the buck than a full-on luxury sedan, and tending to be roomier, too. And yet it's that dilution of dedicated purpose that keeps these models stagnant in showrooms compared to the more luxurious – and certainly to the more economical. It's hard to raise an eyebrow here. So it goes with the Cadenza. Despite looking a heck of a lot like the previous car, the new Cadenza has been reworked significantly – the use of high-strength steel has doubled, to over 50 percent; the use of hot-stamped steel has tripled; the doors are 16 percent more dent-resistant; the chassis has 35 percent greater torsional rigidity; there's a new subframe (similar to that of the Optima); the front windows are now laminated and there's 13 percent more sound insulation in the A-pillars; there's a full underbody cover and wheel air curtains; it has a new eight-speed transmission – developed in-house; there are 40 fewer pounds of unsprung weight thanks to aluminum parts; the brakes are bigger; and there's a bevy of upscale tech features – but we lost you halfway through that paragraph. The styling is a little sharper than the outgoing model's – it's not going to blow your pants off, but it's hardly a bad-looking car. The updated design features Kia's now-trademark quad-LED setup within the lower front grilles, and the main grille is a concave affair – base models get a "Diamond Butterfly" insert you know from other Kia models, and higher-end Cadenzas get "Intaglio" vertical slats.
