Toyota recalls power window switches for 6.5 million vehicles [UPDATE]

UPDATE: There was one incident of someone in the US getting a burn to the hand from this issue Toyota spokesperson Cindy Knight tells Autoblog that. "We have 11 reports where part of the door trim and/or switch was burnt," she said. The company isn't aware of any crashes from the problem, though. Because of a potential short circuit in the driver's side power window switch, Toyota is recalling 6.5 million vehicles worldwide, Reuters reports. Of those, the automaker says around 2 million are in the US. The affected models here are: 2007 and 2009 Camry and Camry Hybrid 2009-2011 Corolla 2008-2011 Highlander and Highlander Hybrid 2009-2011 Matrix 2006-2011 RAV4 2009-2011 Sequoia 2009-2011 Tundra 2006-2010 Yaris 2009-2011 Scion xB 2009-2010 Scion xD According to Toyota, the switch might not have received adequate lubricant grease during manufacturing, and over time this could lead to a short circuit. In a worst-case scenario, the part might even overheat, melt and cause a fire. As a fix, dealers will inspect the component on these vehicles and apply heat-resistant grease to it, and any broken examples will have an internal circuit board replaced. Toyota already issued one recall for this problem in 2012 when it had to repair 7.5 million vehicles globally from the 2007-2009 model years, including 2.5 million in the US. These latest models had the grease applied in a different way.

The involved vehicles include certain: 2007 and 2009 Camry and Camry Hybrid 2009-2011 Corolla 2008-2011 Highlander and Highlander Hybrid 2009-2011 Matrix 2006-2011 RAV4 2009-2011 Sequoia 2009-2011 Tundra 2006-2010 Yaris 2009-2011 Scion xB 2009-2010 Scion xD The Power Window Master Switch in the involved vehicles may have been manufactured with insufficient lubricant grease. If not enough grease is applied, under certain conditions the switch may develop a short circuit that can cause the switch assembly to overheat and melt. A melting switch can produce smoke and potentially lead to a fire. Toyota previously recalled certain 2007-2009 model year vehicles for a similar condition.

Toyota's hydrogen fuel cell Mirai isn't good enough to be a Lexus

It looks like the first hydrogen fuel-cell vehicle from Lexus will be faster than previously advertised, but it will get to the market slower than expected. It's all part of the paradox involved with Toyota looking to broaden its fuel-cell technology beyond the Mirai. Either way, the first Lexus fuel-cell vehicle is slated to start sales by the end of the decade, said Auto Express, citing comments from Alain Uyttenhoven, head of Lexus Europe. Uyttenhoven noted that it'd take an SUV to provide enough space to accommodate the packaging for the Lexus fuel cell powertrain. That comment may imply that the hydrogen-fueled powertrain from Lexus will offer similar performance to that of the Lexus RX450h hybrid SUV. That model delivers 300 horsepower and boasts a 0 to 60 mile-per-hour time of about seven seconds. Such a mill would be a departure from what we'd previously reported on Toyota's plans to expand its fuel-cell technology to its Lexus luxury badge. With Toyota believed to be planning to unveil as many as three fuel-cell models in time for the 2020 Summer Olympics in Tokyo, the Japanese automaker said early last year that it may have a Lexus fuel-cell vehicle available as soon as 2017, while reports suggesting the model would be a Lexus LS-based sedan. Additionally, the Mirai's fuel-cell powertrain had been believed to be the platform for the proposed Lexus fuel cell from the moment that model started sales in California last year. Apparently, though, the Mirai's 152-horsepower powertrain, coupled with a full-tank range that would be about 20 percent less than the 300-mile Mirai, isn't up to snuff for Lexus duty.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
