NHTSA opens investigation into 130k Nissan Versas for breaking springs

The National Highway Traffic Safety Administration has opened a preliminary evaluation into a suspension problem that could affect an estimated 130,000 Nissan Versas from 2008-2010. According to the government agency's documentation (here as a PDF), there have been 93 complaints of the front coil springs fracturing while driving in these vehicles. Based on reports so far, it appears to NHTSA that this problem can happen at any speed and without warning. When the spring breaks, the pieces can also puncture a tire or brake line. A preliminary evaluation sets out to investigate "the scope, frequency and safety-related consequence" of the potential problem. According to a portion of a statement from the automaker to Autoblog, "Nissan is cooperating fully to answer the agency's questions regarding this issue in a timely manner." INVESTIGATION Subject : Front Coil Spring Fracture Date Investigation Opened: MAY 13, 2015 Date Investigation Closed: Open NHTSA Action Number: PE15019 Component(s): SUSPENSION All Products Associated with this Investigation Vehicle Make Model Model Year(s) NISSAN VERSA 2008-2010 Details Manufacturer: Nissan North America, Inc. SUMMARY: The Office of Defects Investigation (ODI) has received 93 complaints (VOQs) alleging incidents of front suspension coil spring fracture in model year (MY) 2008 through 2010 Nissan Versa passenger cars. Preliminary analysis of the complaints indicates that the coil spring failures occur without warning and can happen at any speed. One complaint (VOQ #10663102) reported the passenger-side coil spring fractured while traveling at 65 mph and caused a sudden tire failure by cutting the inner sidewall 360 degrees. Another complaint ( VOQ #10680740) reported the passenger-side coil spring fractured while traveling 40 mph and result in tire puncture and brake line failure. ODI has also received EWR field report information relating to coil spring failures in the subject vehicles. A Preliminary Evaluation has been opened to assess the scope, frequency and safety-related consequence of the alleged defect.

Four Wheeler crowns Ultimate Factory 4x4... who wins?

Nearly every automaker doing business in the SUV or pickup truck segments offers a package designed to improve the off-road capabilities of its wares. But, of course, not all such factory kits are created equal. How, then, to separate the wheat from the chaff? Gather each of them up and put them through their paces, naturally.
The folks from Four Wheeler and PickupTrucks.com joined forces to run just such a comparison test, with the winner named the Ultimate Factory 4x4. A total of seven vehicles showed up to the fight: the 2012 Ford F-150 SVT Raptor, 2013 Jeep Wrangler Rubicon, 2012 Nissan Frontier PRO-4X and Xterra PRO-4X, 2012 Ram Power Wagon, and 2012 Toyota 4Runner Trail and Tacoma TRD T|X Baja Series.
With the contestants in place, the whole crew put each vehicle through a battery of tests that included skidpad and acceleration measurements, a hillclimb, a rocky stairstep course and a rock garden. Considering the nature of the beasts, on-road ride and comfort were not part of the routine.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.
