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.

2020 Mazda CX-5 diesel is still, and perhaps forever, MIA

Halfway through 2020, the most recent Mazda CX-5 diesel you can find anywhere in the U.S. is a 2019 model year — the only one offered so far. With automaker factories beginning their model-year turnovers shortly, CarsDirect did some poking around as to the fate of an oil-burning 2020 CX-5. The outlet couldn't get definitive answers, but a host of secondary evidence suggests the diesel crossover will skip this year, naturally leading to the question of whether the model will skip this market from now on.  Asked in April about the crossover's fate or its arrival, Mazda would only say that "with the current state of the world, many things are tentative." The following month, the automaker's early fleet ordering guide pegged this month as marking the end of CX-5 production, 2021MY crossovers starting down lines in August. Mazda had nothing to say about that information, either. When CarsDirect got in touch again for this latest report, Mazda professed the delay has nothing to do with emissions certification. Then the wall went up again, the only other comment being, "We cannot confirm any details for the CX-5 Diesel at this time."    We're speculating, but at this point, even if Mazda could get 2020MY CX-5 diesels on the lot, why should the automaker bother? The challenges for diesel in general, and this expression of diesel particularly, are clear to everyone; our last post on the CUV, six months ago, was about the five-figure discounts dealers were offering. A quick check on Autotrader at the time of writing shows 45 examples of the 2019 CX-5 diesel available nationwide, plenty of them still priced in the low- to mid-thirties. On Autotrader Canada, which specifies vehicle availability beyond the "1,000+ Results" on the American site, there are 6,135 CX-5s listed nationwide, only 58 of them diesel. Canadian outlet Motor Illustrated wrote, "Mazda recently told us they had a lot of Mercedes-Benz GLE diesel owners and other diesel fans with upscale models trade for a CX-5 diesel." Apparently luxury diesel crossover conquest buyers aren't numerous enough to support a model line. The gasoline versions of the 2020 Mazda CX-5 launched in November last year. It shouldn't take that long for us to find out about the fate of the 2020 CX-5 diesel, or if there will be a 2021 model. Related Video:    

Mazda development chief discusses future rotary platform

The switch can again be flicked from "The Rotary Engine is Doomed" to "The Rotary Engine Lives!" Mazda is re-tooling the once nearly forgotten rotary to work as a range extender for hybrid vehicles, with a chance for it to do even more than that. The latest information sounds rather promising for those still holding out a candle for the rotary. Mazda's powertrain development chief, Ichiro Hirose discussed future rotary plans with the Australian Drive at the CX-30 crossover's launch. Hirose told Australia's Drive that Mazda is currently working with a very flexible and efficient rotary hybrid platform that doesn't necessarily come with the heavy emissions and fuel consumption baggage the rotary engine has earlier been saddled with. Hirose calls the rotary-based solution "XEV," referring to its adaptability. "It has the generator function and also it can be used to provide the drive force to give you traction. [...] Because the rotary engine is compact in terms of its packaging size [and] if we should choose to do so we can have the generator, rotary engine and electric motor all in one [driveline] because of the small packaging." The result is an electrified platform that could be made to work as a mild hybrid, series hybrid or a battery electric vehicle with a rotary range extender (if given a plug), depending of the required implementation. It's as if Mazda had a slider to adjust the balance of using a rotary engine and using electric power, to make the platform more of a jack-of-all-trades. Hirose explained: "If you reduce the other way around it could be a pure battery-electric, using really the rotary engine as a range extender and, according to the balance, you can even provide something akin to the series hybrid that is providing the drive force. [...] So, we are looking at a wider coverage and scope. Based on this architecture it allows us to do that, to explore the huge range of applications we can have with the rotary." The platform would also be flexible when it comes to meeting various stringent emissions standards. To be able to sell XEV-based vehicles globally would mean introducing a certain setup for one region and one for another, keeping in mind when the rotary power would kick in and how. While Hirose keeps the question open whether these vehicles would make it for sale in the United States, he says Mazda would be able to make them pass U.S regulations. "I'm just saying that — theoretically — if we were to introduce it in the U.S.
