Mazda recalls 1.37 million older vehicles for ignition switch short [UPDATE]

UPDATE: Mazda has confirmed to Autoblog that NHTSA's figures and list of effected models are accurate. Mazda is recalling 1,368,500 older vehicles in the US that date as far back as the late '80s because a potential short circuit in the ignition switch could cause a fire. According to the National Highway Traffic Safety Administration, the models include: 1990-1995 323 1993-1998 626 1993-1995 929 1989-1998 MPV 1993-1997 MX-6 1992-1993 MX-3 1990-1998 Protege Mazda reports that over time the grease around the switch's contact points can carbonize and become conductive, which can eventually lead to a short circuit. In some cases this results in smoke, but it could also lead to a fire. According to company spokesperson Tamara Mlynarczyk to Autoblog, there're no accidents, injuries, or fires in the US. Once the vehicle is running, the potential fault also doesn't affect drivability. Documents from NHTSA (as a PDF), indicate there was a fire in one of these vehicles in Japan in 2002 that could have been linked to this issue. The recall should begin in December. In its announcement of the issue below, Mazda reports 1.2 million vehicles affected and includes the 1990-1996 323/Protege. Autoblog has reached out to the company to understand the discrepancy.

In the affected vehicles, grease applied to the contact points inside the ignition switch may become conductive and overheat. CONSEQUENCE: If the ignition switch overheats there would be an increased risk of a fire. REMEDY: Mazda will notify owners, and dealers will replace the ignition switch, free of charge. The recall is expected to begin December 15, 2015. Owners may contact Mazda Customer Experience Center at 1-800-222-5500, option#6. Mazda's number for this recall is 8715J.

Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.

2020 Mazda CX-30 Review & Buying Guide | The new sporty

Is it a sporty crossover? Is it a tall hatchback? However you want to view it, the new 2020 Mazda CX-30 is a compelling new entry that delivers the sort of engaging driving experience and premium cabin environment you get in the company's 3 hatchback, but with the higher seating position of a crossover. Basically, if that Mazda3 had a child with the bigger CX-5, this is pretty much what you'd get, and we have to say it's a pretty good kid.   In terms of size, the CX-30 fits into a niche of in-betweener SUVs that slots between compact models like the CX-5 (plus the Honda CR-V, Toyota RAV4, etc.) and sub-compact ones like the Mazda CX-3 (plus the Honda HR-V, Hyundai Kona, etc.). If you don't have small children, and the car seats and strollers that come with them, it's a size that should make sense. The price is compelling too, especially when you consider the CX-30's high-end cabin and just how terrific it is to drive. With its tautly tuned chassis, communicative steering and sharp throttle response, the best words to describe it are "budget Porsche." Now, we should note that the Mazda3 is even better to drive and pretty much offers the same cabin space, design and quality. We also think it looks better. Nevertheless, people like sitting up high, and the CX-30 definitely satisfies that requirement. What's new for 2020? The Mazda CX-30 is an all-new model. What's the CX-30's interior and in-car technology like? Like the Mazda3 with which it shares so much, the CX-30's cabin makes you go "wow" considering its price and the vehicles with which it competes. Whatever trim level you're considering, the key to this wow factor is how Mazda's new dash design scheme removes visual clutter by reducing switchgear and effectively hiding air vents and door handles. It's then augmented by standard two- or three-tone color schemes – cars with cloth or leatherette vinyl upholstery are accented with black and blue dash/door trim, while those with leather get black and brown. For a car in the $20,000-$30,000 range, it looks and feels special. It's also of a high quality and quite functional. The steering wheel, which looks sensational, is an absolute treat to hold and has intelligently designed buttons/switches for the infotainment and cruise controls. There's considerable center console space, including a configurable under-armrest bin, and a decently sized forward bin for a smartphone.
