Feds investigating 2010-11 Mazda CX-9 CUVs over braking issues

The National Highway Traffic Safety Administration is investigating 62,000, 2010-2011 Mazda CX-9 models over brake problems. The government safety watchdog says it has received seven complaints of an observed loss of power braking power to stop the crossover, according to the The Detroit News.
The NHTSA complaints say that the problem causes a hard pedal, increased braking effort and reduced braking effectiveness. Some complaints allege that they hear a hissing noise during braking similar to the sound of air leaving the tires. No injuries or crashes have been reported.
"As always, we are fully cooperating with NHTSA on their investigation. We cannot comment further at this time," said Mazda spokesperson Tamara Mlynarczyk to The Detroit News.

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.

The 2016 Mazda MX-5 Miata Has Arrived

Ladies and gentlemen, meet the 2016 Mazda MX-5 Miata. The highly anticipated fourth-generation (ND) model made its official debut in Monterey, CA this evening, and while details are slim (as in, we have practically none), there's one big thing to talk about: less weight. Yes, Mazda has confirmed that the new Miata sheds some 220 pounds over the model it replaces, and is "the most compact of any generation MX-5 so far." For those keeping track, that means the new MX-5 should weigh in somewhere around 2,200 pounds. Mazda's Kodo design language is obvious here, with a seriously wide and low demeanor, and a mix of flowing lines and sharp angles. We don't have any powertrain details to report as of this writing, but Mazda says the full suite of Skyactiv technologies are onboard, and the motto in creating this car was "Innovate in order to preserve." Click the image above to see the new MX-5 Miata in high resolution, click below for the press release, and stay tuned to this space for more details as they break. UPDATE: Want more Miata details? Please check out our in-depth firsthand report from the Miata's reveal event by clicking here and see the first-ever rolling footage of the car in our brief video here. Mazda Unveils All-New Mazda MX-5 HIROSHIMA, Japan-Mazda Motor Corporation today celebrated the unveiling of the fourth generation Mazda MX-5 (known as Roadster in Japan) together with fans at events held simultaneously in Japan, USA and Spain. The all-new MX-5, which adopts both SKYACTIV TECHNOLOGY and Mazda's KODO-Soul of Motion design language, will be rolled out to global markets starting in 2015. The MX-5 is an iconic model representing Mazda's vehicle-engineering philosophy-the pursuit of driving pleasure. "Innovate in order to preserve" was the motto for the fourth generation, as the development team searched for innovations that go beyond simple evolution. Environmental and safety demands are much more stringent than they were when the first generation MX-5 was introduced 25 years ago, but the fourth generation stays true to the model's original aim of offering the pure driving fun that only a lightweight sports car can. It achieves this through the adoption of SKYACTIV TECHNOLOGY and refinement of its appeal to the senses and sensations through which people enjoy cars. The design of the all-new MX-5 reveals another layer to Mazda's KODO design language.
