Feds investigating Mazda CX-9 over suspension problems

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2007-2008 Mazda CX-9 because the lower ball joint in the front suspension can potentially separate while driving. An estimated 54,000 examples of the crossover might be affected. The investigation was prompted by six complaints of this happening on the road. Because the complaints are coming more rapidly as of late, NHTSA thinks the issue could be getting worse. The problem also appears to be more prevalent in states that use salt on their roads in the winter. None of the failures caused any injuries, and all but one happened at 20 miles per hour or slower. NHTSA's preliminary evaluations "assess the scope, frequency, and safety consequence" of a potential problem and can sometimes lead to recalls.

SUMMARY: The Office of Defects Investigation (ODI) has received six (6) complaints (VOQs) alleging incidents of front suspension LBJ separation in MY 2007 through 2008 Mazda CX-9 vehicles. The reports appear to show an increasing trend. One of the separations allegedly occurred at 40 mph and the other 5 incidents occurred at speeds between 0 and 20 mph. The first VOQ was received in October 2013, followed by 2 reports in late 2014 and 3 reports in the first 5 months of 2015. Four of the VOQs are from states using high volumes of road salts (?salt states?) which, for purposes of this investigation, include: Connecticut, District of Columbia, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin. The other VOQs were from northern Virginia, which borders the ?salt state? region, and South Carolina. ODI also identified EWR field report data related to the alleged defect in the subject vehicles. A preliminary investigation is being opened to assess the scope, frequency, and safety consequence of the alleged defect. The six VOQs associated with this investigation are: 10717510, 10714469, 10695142, 10668978, 10640541, and 10546535.

Car and Driver lists 10Best for 2013, same as it ever was

Forgive us for having the distinct feeling of déjà vu, but it certainly feels like we've been here before. By that we are referring Car and Driver and the announcement of its annual 10Best vehicles for 2013. To be sure, it's an impressive selection of cars that combine heart-pounding performance and frugal sensibilities, but it also represents something of a broken record on the part of C/D. We're not so sure that's a flaw, though, as the resulting list is tough to argue with.
Vehicles like the Ford Mustang, Porsche Boxster, and BMW 3 Series have maintained their high-horsepower spots on this list for several years now. Even on the more practical and nimble end, the Honda Accord, Honda Fit and Mazda Miata have not budged. These continued spots are even in light of redesigns for some vehicles such as the Accord, Boxster and 3 Series.
In fact, the only newcomer to the 10Best list this year are the Scion FR-S/Subaru BRZ twins, which knocked out the Cadillac CTS-V. We think it would have been a huge misstep to have excluded the FR-S/BRZ, even in light of the supercharged Caddy's lamentable departure from 10Best.

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.
