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 CX-30 crossover will have its U.S. debut at L.A. Auto Show

After debuting at the Geneva Motor Show earlier this year, the Mazda CX-30 is ready to relocate to the U.S., and is now preparing to meet its future compatriots at the LA Auto Show. The small crossover — whose name is a workaround due to the Chinese-market CX-4 crossover — is five inches longer than the new Mazda3 hatchback and five inches shorter than the CX-5 crossover. Its appeal is intended to be a mix of high maneuverability and roominess for occupants and cargo, not to mention being the second vehicle in the lineup to adopt the evolved Kodo design language first expressed on the latest Mazda3.  In Europe, the CX-30 offers buyers a range of engines from a Skyactiv-D 1.8-liter diesel to the new Skyactiv-X engine with gasoline compression ignition. Last month, Motor Trend dug up a California Air Resources Board document listing the two engines and two transmissions for the North American market. Our continent gets the 2.0-liter four-cylinder mated to a six-speed manual or a six-speed automatic, and a 2.5-liter four-cylinder mated solely to a six-speed auto. The smaller engine and manual transmission are expected to be reserved for Canadian and Mexican buyers. The U.S. likely gets the 2.5-liter, the engine that makes 186 horsepower and 186 pound-feet of torque in the Mazda3 and 187 hp in the CX-5.  Mazda's i-Activ all-wheel drive is predicted from launch, and safety features should include front cross-traffic alert, adaptive cruise control, and driver monitoring linked to a Smart Brake Support system that cuts the reaction time to issue a the driver a brake warning. The CX-30 will share the Mazda stand with the 2019 Mazda MX-5/Miata RF, refreshed 2020 CX-5 and 2020 CX-9 crossovers, the 2020 Mazda 3, and Mazda3 TCR racer. Anyone with some free time at 1:20 p.m. Pacific Time on November 11 is welcome to stream the press conference at Mazda's YouTube channel.

Mazda officially hints MX-30 could get a rotary range-extender

Mazda recently penned a paean to itself celebrating 100 years in business. This, naturally, meant the document also served as a love letter to the rotary engine, since, "The joy of driving, lightweight design and the rotary engine [are] three elements that define Mazda’s DNA." One of those elements has been AWOL for eight years, since the end of RX-8 production. After years of rumor feverish enough to impress Slenderman, two years ago Mazda announced it was prepping a rotary range-extender engine for a model to debut in 2020. Here we are in the anticipated year, and we still don't know anything else about that vehicle — or perhaps we do. When Mazda debuted the MX-30 battery-electric crossover in Tokyo last year, it bore an e-SkyActive powertrain with a 35.5-kWh battery sending current to an e-motor on the front axle producing 141 horsepower and 195 pound-feet of torque. With a range of around 130 miles on the European cycle, even though the crossover was meant for markets like Europe and Japan, almost everyone chimed, "This would be perfect for that range-extender engine." The automaker has hinted at that very thing for its centenary celebration. In a paragraph touching on alt-fuel RX-7 variants, the Mazda press department wrote, "Later, the company developed a prototype Mazda2 EV with a small single-rotor engine used as a range extender. A similar system could find its way onto the Mazda MX-30, a brand new battery electric crossover SUV arriving at dealerships this year." The word "could" didn't make the leap from the printed page into the video translation of the presser, a Mazda video on "The Dream Engine" ending with footage of the MX-30 rolling under the caption, "Mazda MX-30 with rotary range extender." When asked, Mazda's head of R&D in Europe explained the battery size and resultant range with wheel-to-well considerations that factored energy input and emissions output from making the battery to exchanging the battery after 100,000 miles of driving. Since the carmaker doesn't deem the pure-electric MX-30 suited to the U.S., the question bubbling beneath the latest news is whether this revised model with more range could make it here. Given a suitably sized fuel tank that could power the little people mover beyond 150 miles on U.S. roads, and a fair price, we suspect there'd be a great deal of interest. Now, Mazda, about that rotary-powered RX-7 ... Related Video:
