Five automakers now being investigated by NHTSA for airbag woes

It appears that Toyota's renotification to owners of recalled vehicles from last year is just the tip of the iceberg for what could potentially be a much larger industry-wide recall. The National Highway Traffic Safety Administration is opening a preliminary evaluation investigation into roughly 1.1 million vehicles from Chrysler, Honda, Mazda, Nissan, Toyota and parts supplier Takata regarding faulty airbag inflators in several models.
NHTSA has received six reports - three directly, two from Takata and one from Toyota - of vehicles with ruptured airbag inflators from 2002-2006, which resulted in three injuries. So far, all six incidents have occurred in high humidity areas like Florida and Puerto Rico. According to Toyota's latest recall announcement, the inflators may have an improper propellant that could cause it to rupture in a crash and the bag to deploy abnormally.
This new investigation follows a previous recall from April 2013 of about 3.4 million vehicles worldwide for the airbag inflators from Takata. As Autoblog reported, Toyota jumpstarted the new situation when it found that the original list of serial numbers for the faulty part was incomplete and discovered more cars in need of replacement. Honda and Nissan told us that they were investigating whether further models would need called in again as well. Mazda told Autoblog: "Regarding the current Takata situation, we're working closely with NHTSA and investigating the situation, but nothing else to report at this time." Chrysler Group responded to us with the statement: "Chrysler Group engineers are conducting the appropriate analysis. The Company will cooperate fully with the National Highway Traffic Administration."

Sweating the small stuff | 2017 Mazda CX-5 First Drive

The 2017 Mazda CX-5's door handles got their own design study. They got their own graphs, maths, and a team of people scientifically analyzing how humans interact with them. There was a whole to-do. And yet, you look at them back-to-back with their predecessors, a Spockian eyebrow reaching to the stars, and wonder what all the fuss was about. But apparently they're better. They're also perfectly illustrative of the entire effort to re-engineer and improve Mazda's best-selling model. At first, the 2017 Mazda CX-5 seems like a sensible evolution of its well-loved predecessor – there's sexier styling, a more premium cabin, and additional features, but the dimensions and engine specs look awfully similar. It certainly looks like one of those "the old car's great, let's not overthink the new one" redesigns. Except it isn't. Dig deeper and you'll see just how much meticulous work – from the door handles to the throttle response – went into making the new CX-5 a crossover that thoroughly trounces the majority of its competition. Take the efforts to make it quieter. According to Mazda's internal measurements, the sound-quelling improvements made for the CX-5's 2016 refresh already made it one of the quietest compact SUVs on the market. That apparently wasn't good enough. To what seems like an absurd degree, Mazda's engineers obsessively examined every nook, cranny, corner, and crevice to sniff out noise and eliminate it. Gaps were filled, insulation was injected, seals were added, air was redirected, glass was double glazed, and carpet replaced plastic coverings. It would seem that the Society of Persnickety Engineers is well represented at Mazda HQ. "I'm not sure how they found some of these," said Mazda vehicle development engineer Dave Coleman with a shake of his head, almost amused by the obsession and dedication of his colleagues across the proverbial hall in the sound-deadening department. (He goes over many of their enhancements in the video below.) And it worked. The new CX-5 is indeed incredibly quiet, even on San Diego's notoriously loud corrugated concrete freeways. It is quiet for a Mazda – a brand previously known for the exact opposite – and the entire segment. Even the fairly quiet 2017 Honda CR-V we drove on the same freeways on the way to San Diego couldn't match it. Actually, much of the driving experience can't be matched by a competitor.

Mazda G-Vectoring Control makes driving better without you knowing

Mazda has just spent eight years developing a new technology that will make its new cars a lot more fun to drive, even if you have absolutely no idea that it's working. And subtlety's the point, Mazda engineers told us at a press event at Mazda Raceway Laguna Seca. In fact, the effects of what they've dubbed G-Vectoring Control are so fine that the marketing and PR teams are at a loss for how to do their jobs with it. "The engineers have done their work," said Mazda Director of Communications Jeremy Barnes, "But how do we get the message across?" The basic premise is this: G-Vectoring activates only when the car's on-board computer reads simultaneous steering and throttle input. The data — including throttle position, steering angle, and, crucially, how quickly you're adjusting the steering angle — are then funneled through an algorithm to reduce engine torque, which transfers vehicle weight, adding more grip to the wheels that need it. The system will appear first on 2017 Mazda6 sedans arriving in showrooms later this year, followed by the 2017 Mazda3. Actually, "subtle" does not even begin to describe the effect. G-Vectoring Control can detect as much as one tenth of one degree of steering angle, and changes the cornering forces only 0.1 to 0.5 g as a result. "That's less than the human body can feel," explained Vehicle Development Engineer Dave Coleman. In practice, G-Vectoring reduces the steering angle at turn-in, as well as the rate at which one turns the wheel. To demonstrate, Director of R&D Kelvin Hiraishi rode shotgun with us in a specially equipped Mazda6 that allowed him to turn G-Vectoring on or off at the push of a button (production cars will always have it on). Hiraishi had us drive a number of courses, including Mazda Raceway Laguna Seca itself, while an engineer measured our steering inputs with a laptop Matrix'd into the car's electronic brain. I drove the same course several times with the same car in the same conditions, with cruise control locked and the system turned on or off. Lo and behold, with G-Vectoring activated, the engineer's output graph showed that my steering inputs were indeed reduced ever so slightly. There were two times that G-Vectoring was markedly noticeable. The first on a turn with a minor banking toward the outside, and the second was during cornering over an artificially wet section of the course — in other words, when the car was at the limits of adhesion.
