Nissan Quest under investigation for inaccurate fuel gauges

After receiving 12 complaints in the last 14 months, the National Highway Traffic Safety Administration has begun a preliminary investigation into a fuel gauge issue with the 2007 Nissan Quest. Drivers have reported that the fuel level gauge will show there's gas in the tank when there actually isn't - in two cases, the digital distance-to-empty gauge indicated more than 70 miles of remaining range - and it will stall out.
This is the second time the 2007-model-year Quest has been involved in the same fuel gauge issue. In 2010 Nissan recalled seven models, including the Quest, from the 2005-2008 model years because of faulty fuel readings. The 12 vehicles in this latest complaint could have slipped through the cracks then, but we'll find out more when NHTSA updates its progress with the investigation into the estimated 37,656 units.

Will Nissan's Cummins deal upset Ram's marketing mojo? [w/poll]

Ram has used Cummins engines in its heavy duty trucks since 1989, and it is the only pickup truck brand to use products from the Indiana-based engine maker. With the announcement that the next Nissan Titan will also use a Cummins powerplant, and a Nissan spokesman having already said "We will definitely leverage the Cummins brand name," a piece in Automotive News wonders whether the deal will affect the way Ram markets its tie-up with Cummins.
The question really is, how intense is this competition? While it is the first time that trucks from two different brands have used Cummins engines, they'll be two different engines in two different kinds of trucks; Nissan is going to put a 5.0-liter turbodiesel in a non-heavy-duty Titan, Ram only uses its 6.7-liter, inline six-cylinder turbodiesel in heavy-duty offerings. The diesel that Ram will offer in its light-duty, half-ton 1500 is a 3.0-liter V6 EcoDiesel with 240 horsepower and 420 pound-feet of torque - compared to about 300 hp and 550 lb-ft expected from the Titan's Cummins - and its marketing so far has focused on the fuel economy gains.
If Nissan was going to prove its commitment to the segment, it had to do something compelling. If we're talking about sales competition between Ram and Nissan, Ram has sold 201,633 trucks as of July this year, up 24.2 percent, 31,314 of those sales coming last month; Nissan has sold 10,020 Titans through the end of July, down 21.1 percent, and just 1,168 in July itself. Nissan's new truck boss - who hopped there from Ram - said that buyers have asked for a powerful turbodiesel in something other than a heavy duty pickup, and from what we've read on various comment boards, the pickup truck crowd is excited about Nissan's move.

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:
