Nissan owners complain to feds about rusting floors

"You can feel it's soft right here," Jeff Talman told KSHB. "Right under his driver and passenger seats, the floorboards were rusting from the inside out," a KSHB reporter said. "This is a seven-inch area where it's actually rotted up here," Talman said. That was Jeff Talman, just one of many who have had issues with rusting floorboards in Nissan Altimas. KSHB reported the National Highway Traffic Safety Administration has received more than 400 complains about rust issues in 2002-2006 models. NBC highlighted a Chicago woman's 2005 car, which had rusted so much the floorboards were actually crumbling. "The hole was big enough to fit her foot through," NBC reporter Tom Costello said. "I'm not Fred Flintstone. This is not a good thing," Marie DeMaria said. While NBC reports snow and road salt could account for rust damage in some vehicles, that's probably not the cause in places that don't get snow and ice. And complaints are coming in from all over the country. Both Toyota and Ford have recalled hundreds of thousands of vehicles in the past few years because rusting underbody parts made the vehicles fall apart. Despite the number of complaints, Nissan isn't recalling the Altima vehicle models in question. "It's not a safety recall problem that's going to cause immediate death and injury if you have a hole in the floor. As a result of that, what we've seen is that Nissan has been able to get away with this problem," auto safety expert Sean Kane told WBZ-TV. KSHB reports the age of the cars is another way Nissan is able to avoid covering cost to fix them. "Once it's out of the warranty period, obviously they don't have any legal obligation. It becomes more of a customer service issue of whether they want to deal with it or not," body shop owner Bill Eveland said. NBC did reach out to Nissan for comment, but the carmaker reiterated that both it and the National Highway Traffic Safety Administration do not consider the rust problem to be a safety defect.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:

This map reveals the cleanest vehicles based on location

Naysayers love to point out how dirty the electricity grid mix is when it comes to charging electric vehicles. Curmudgeons are eager to jump into any conversation about EVs to enlighten the lucky listeners about how plug-in cars contribute to pollution, sometimes even throwing in a dash of climate-change denial for good measure. (Thanks, buddy. Pray, tell me more about the plight of oppressed SUV owners.) Unless someone buys an EV just because they think they're cool (which, yeah, they often are), they probably have at least a passable understanding of their environmental pros and cons. As many EV owners are already aware, location has a lot to do with any particular plug-in car's carbon footprint. Still, there's always more to know, and knowledge is not a bad thing, especially if one uses it to do the right thing. That's why this handy-dandy map from Carnegie Mellon University is so interesting. CMU researchers have compiled information about the lifecycle greenhouse gas emissions of various EVs based on where they're charged, as compared to gasoline-powered vehicles. The researchers looked at the Nissan Leaf, Chevrolet Volt, and Prius Plug-In Hybrid versus the gasoline-dependent Toyota Prius hybrid and the stop-start-equipped Mazda3 with i-ELOOP and compared grams of CO2 emitted per mile. CMU takes into account the grid mix, ambient temperature, and driving patterns. CMU takes into account the grid mix based on county, as well as ambient temperature and driving patterns in terms of miles traveled on the highway or in the city. For instance, if you drive a Nissan Leaf in urban areas of California, Texas, or Florida, your carbon footprint is lower than it would be if you were driving a standard Toyota Prius. However, if you charge your Leaf in the Midwest or the South, for the most part, you've got a larger carbon footprint than the Prius. If you live in the rural Midwest, you'd probably even be better off driving a Mazda3. Throughout the country, the Chevrolet Volt has a larger carbon footprint than the Toyota Prius, but a smaller one than the Mazda3 in a lot of urban counties in the US. The Prius and Prius Plug-In are relatively equal across the US. Having trouble keeping it straight? That's not surprising. The comparisons between plug-in and gasoline vehicles are much more nuanced than the loudest voices usually let on.
