2016 Mazda CX-5 recalled to address failing DRLs

Mazda announced Tuesday that it will recall more than 35,000 examples of the 2016 CX-5 crossover to address an issue that may lead to deterioration or failure of its LED daytime running lights.  In affected models, the gasket used to seal the wiring harness to the LED module was not manufactured to Mazda's specification. As it degrades over time, it can release sulfur, which in turn can potentially corrode the LED control circuit, causing the LEDs themselves to flicker, illuminate poorly or even fail outright.  Per Mazda, there is no alert for this condition, so drivers can potentially lose daytime running light function without realizing it, leaving them tougher to spot in poor light.  The campaign will cover 36,761 CX-5s sold in the U.S. and U.S. territories. Mazda says no accidents or injuries related to the issue have so far been reported.  This new campaign has not yet been published in the National Highway Transportation Safety Administration (NHTSA) recall database, and Mazda's statement did not include details of the proper remedy for the issue or when customers can expect to be contacted to arrange for service.  We expect that all 2016 CX-5s with LED DRLs will receive new harness gaskets and that those showing signs of LED module corrosion will have those replaced as well.  The 2016 CX-5 has been the subject of four other recall campaigns — including one for an improperly torqued steering knuckle bolt and another for a defective fuel filler pipe — but this is the first  new campaign for that model year since 2016.  Related Video: This content is hosted by a third party.

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.

Mazda teases its Tokyo-bound EV again — and it's a crossover coupe

Another 15-second teaser clip, the third so far, stars Mazda's coming electric vehicle in the role of coquette. This time we get a glimpse of the body shape, and coming as a shock to no one since Mazda practically admitted it, we'll be seeing a crossover coupe on the Tokyo Motor Show floor. Mazda says there'll be a few surprises therein, though. The overall line and detailing embody "an expansion of our renowned Kodo design philosophy" at the same time as the EV "explores new directions in design." And within the "uncompromisingly simple" form we're told to expect "a unique door concept, opening your mind." Another couplet in the press release poetry promises a "friendly expression" up front for a new segment entry embodying "futuristic values and changing lifestyles." Well then. This will be Mazda's fourth electric vehicle, but the first meant for mass production. The company built a small batch of the Mazda Demio (our Mazda2) battery electric vehicle in 2012 for the Japanese market, leasing them to government and corporate customers. The following year the automaker built a Mazda Demio EV prototype with a 330-cc rotary-powered range-extender engine. After that came the e-TPV prototype that the company's used to prove out the powertrain going into this month's show car.  The urban-focused electric runner should go on sale next year in markets like Japan, China and Europe, where dense city centers negate the need for sky-high range figures; the 35.5-kWh battery is likely to return a 150-mile range at most. As foretold in the most recent teaser, the interior will deliver an airy sense of space thanks to open spaces between the driver's and passenger's seats. Zoom-Zoom will come with EV internals, too — Autocar recently drove the eTPV prototype and lauded it for being "well-planted," "original to drive" and "more like a car in the traditional sense of the word."
