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.

Sorry, rotary fans, Mazda's RX Vision probably won't happen

Mazda is doing a lot of things the right way in this age of beige-ness. It just crammed a turbocharged inline-four into the improved CX-9, a bold move unto itself, and one that should also be heartening for Mazdaspeed fans. Wouldn't that engine make for a swell Mazdaspeed3 or Mazdaspeed6? There's a reasonable ray of hope there, but not necessarily a guarantee. The RX Vision, though, is a pipe dream. Mazda is smart to keep the rotary dream alive. It's smart to keep developing it in back rooms and to keep the idea on the public's mind. Credit where credit's due: Mazda has solved some of the stickiest issues the rotary engine has, through savvy engineering and perseverance. We've seen promising patent filings for the Skyactiv-R engine, which is supposed to be found in the RX Vision concept. Mazda uses every opportunity to remind us that development is continuing and that the company would love to bring a rotary-powered sportscar to production. I believe it. But the RX Vision is just a design study. And there are some harsh realities about rotary engine emissions and fuel economy standards that are difficult for modern piston engines to achieve without expensive componentry. Emissions and fuel economy are both bugbears of the rotary, in case you've forgotten. And that explains Mazda's interest in running rotaries on hydrogen, but down that road lie infrastructure challenges as daunting as making a gasoline-powered rotary burn as clean as one of Mazda's Skyactiv piston engines. All this is meant to put Mazda's recent comments to Top Gear in context. Mazda's design director, Kevin Rice, spoke to TG at the Concorso d'Eleganza Villa D'Este, and was waving Mazda's rotary flag quite enthusiastically. "In the back rooms at Mazda, we're still developing it," Rice said, "and when the world's ready to buy another rotary, we'll be ready to provide it." I'd like that to be a comforting statement, but given the realities of fuel economy and emissions regulations and Mazda's position in the market, it seems like a hollow platitude. "When the world's ready" is just another way of saying "when we solve the fundamental issues with this engine layout, and there's an unambiguous market study that shows we can build these cars and make a profit, we'll consider it." That seems like a lot of "ifs". Perhaps Mazda does have a clean-burning, efficient, cheap-to-produce rotary running on an engine dyno in Hiroshima, and it's prepping an RX-9 for the next auto show.

2021 Mazda3 2.5 Turbo is official, with automatic transmission only

The Mazda3 Turbo is here, and while it’s no Mazdaspeed, this is still a happy day for enthusiasts. Its full, official name is the 2021 Mazda3 2.5 Turbo, which begins to describe it perfectly. Just as was expected, Mazda has taken its 2.5-liter turbocharged four-cylinder off its shelf and plopped it into the compact 3. When run on 93 octane fuel, Mazda claims 250 horsepower and 320 pound-feet of torque. You can still run it on 87 octane, but the numbers drop to 227 horsepower and 310 pound-feet of torque. Mazda says this engine has a specific calibration for the Mazda3 “to deliver the unique driving dynamics expected by our most passionate drivers.” The engine delivers a stout low-end shove in its other applications, so perhaps Mazda has found a way to make it more excitable in the upper rev ranges. WeÂ’ll see about that when we drive it. The Turbo is also paired exclusively with all-wheel drive and the six-speed automatic transmission. It is sad to see the six-speed manual being left in the dust here, but Mazda has decided to not offer it as an option. The all-wheel drive system operates the same as the one in the naturally aspirated version, which should hopefully be good enough to mitigate torque steer and understeer. Mazda hasnÂ’t quoted any official acceleration times for the Turbo yet, but we expect it could chop about a second off the carÂ’s 0-60 mph time. Something in the low 6-second range seems plausible. There are no changes to the chassis, suspension or brakes for this model; Mazda says "the current Mazda3, as well as all our vehicles, are always designed and tuned to be focused on dynamic driving. We are confident that the turbo engine will help to refine the already exciting driving experience without the need to add more than is necessary." It does come in a base trim (similar to a base hatchback in content), but even that trim is relatively well-equipped. A Premium Plus Package is available that raises the bar. This package includes leather seats, navigation, HomeLink, Traffic Jam Assist (provides steering inputs below 40 mph to stay in lane), 360-degree camera, rear automatic emergency braking, rear cross-traffic braking and parking sensors in front and back.  Unfortunately, the new driver assistance features we listed above are exclusive to the Turbo and wonÂ’t be available on other Mazda3 models this year.
