Toyota recalling 11,200 Scion iQ models over faulty passenger sensors

Toyota has announced a voluntary recall of 11,200 Scion iQ models from the 2012 and 2013 model years. According to the manufacturer, the problem with these pint-sized hatchbacks concerns the front passenger Occupant Classification System (OCS) weight sensor cables.
The OCS sensors in the front passenger seat control the operation of things like the airbags and seatbelt pre-tensioner. In these affected models, the cables for these sensors located in the seat track can become damaged as the passenger seat slides forward and backward. And if the cables are damaged, the airbags and seatbelt pre-tensioner may not function properly.
No injuries or crashes have been reported in conjunction with this issue.

Toyota recalling small number of 2014 FJ Cruisers for possible steering failure

Toyota is issuing a fairly tiny recall to fix a potentially serious problem in the FJ Cruiser. The company is recalling about 120 examples of the rugged SUV from the 2014 model year because the steering can fail. According to Toyota, the intermediate shaft that connects the steering wheel and steering gear box might not be welded correctly and can separate. If this happens, drivers lose steering control, which is obviously a major safety concern. However, the automaker is not aware of any crashes, injuries or fatalities from the problem. On the small number of affected models, Toyota will replace the intermediate shaft with a new one. TOYOTA RECALLS CERTAIN 2014 MODEL YEAR FJ CRUISER VEHICLES TORRANCE, Calif., February 5, 2015 – Toyota Motor Sales, U.S.A., Inc., today announced it will conduct a safety recall of approximately 120 Model Year 2014 FJ Cruiser vehicles. The steering system contains an intermediate shaft, which connects the steering wheel to the steering gear box. In the involved vehicles the intermediate shaft could have received an inadequate weld. Under some circumstances, the weld could separate, resulting in the loss of steering control and increasing the risk of a crash. Toyota is not aware of any crashes, injuries, or fatalities caused by this condition. Owners of the involved vehicles will receive a notification by first class mail. Toyota dealers will replace the intermediate shaft. Detailed information is available at www.toyota.com/recall and by calling Toyota Customer Service at 1-800-331-4331.

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.
