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.

Watch what happens inside a rotary engine

Since it looks like Mazda may very well revive the Wankel rotary engine as a range extender for electric cars, there's no better time to become reacquainted with the quirky internal-combustion engine. And there's hardly a better way to become reacquainted than by peering into a running rotary engine, which you can do with the video above. The video comes to us from the YouTube channel Warped Perception. The channel has already shown what happens inside a conventional internal-combustion piston engine by putting a clear cylinder head on top of a flathead engine. This new video shows off the rotary engine by adding a clear side to a tiny model-airplane engine, something that we weren't aware existed and are glad to know about now. Despite the tiny size, the engine is functionally almost exactly like the bigger versions you'll find in Mazdas from about 1967 to 2012. It has intake and exhaust ports on the edges of the rotor housing, and the triangular rotor swings about in a peanut-shaped housing. For maximum effect, jump to right around the 7:40 timestamp. This is the point at which a bit of acetylene is added to the air-fuel mix for a brighter flame. It's at this point that you can really see when the mixture combusts and how the pressure of the flame pushes the rotor to produce rotational motion. Each stage of the video does slow things down to make everything as clear as possible. Even if you already knew how rotary engines worked, it's still fascinating to watch, first because it's something you don't get to see usually, and also because of the engine's elegant simplicity.

Subaru, Mazda profits dip; both blame exchange rates

While some larger automakers took a beating on Q4 earnings, some of Japan's smaller operations managed to keep their heads just above water despite currency issues and slumping sales industry-wide. Subaru, which capped off its 11th consecutive year of U.S. sales increases, reported a 42-percent drop in operating profit in the final quarter of 2019; Mazda, which operates on an even smaller scale, saw a 76-percent drop.  Per Automotive News, both companies faced challenges apart from navigating currency exchanges.  Subaru Subaru's 2019 was marred by warranty costs stemming from repairs on high-volume models, including the Impreza and Crosstrek. Despite the drop in profit, company revenues only slid 2.3 percent. The company also says that it has managed to curtail incentive spending, largely thanks to replacement models that needed less help moving out of showrooms.  America remained a bright spot, with 2019 sales volumes increasing by nearly 3 percent over 2018. Subaru is hoping that figure will increase to 4.0 percent in 2020. Subaru's wholesale deliveries also increased in western Europe, but dropped precipitously (28 percent) in the company's home market.  Mazda The smaller Mazda faced similar challenges, but its 2019 lacked some of Subaru's more dramatic bright spots. Worldwide shipments of new vehicles dropped by 8 percent, aiding a revenue decline of 5 percent. Mazda's vehicles remained profitable on a per-unit basis, but only just.  Mazda has been undergoing aggressive cost-cutting measures, but even those were no match for reduced volumes and unattractive currency exchange rates.  Despite these challenges, both companies are keeping their earnings outlooks unchanged. The fourth quarter of 2019 represented the third quarter in both companies' fiscal years, which will end in March.  Related Video: This content is hosted by a third party.
