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.

Why it's difficult to accurately test the efficiency of a plug-in car

When it comes to electric vehicles and plug-ins in general, the Environmental Protection Agency-certified range is a hugely important number. While actual range anxiety is largely psychological, the magic number does provide a point of comparison of buyers considering one EV over another. The driving distance is also often touted by automakers when marketing their models. Unfortunately, as Green Car Reports finds in a recent deep dive, the way the EPA calculates the figure is a convoluted mess, and discovering the reasons why is definitely worth the read. The issue isn't about bad science but instead comes down to vague wording. The EPA's accepted range test is sourced from an evaluation called J-1634 from the Society of Automotive Engineers, and it seems to provide balanced results for vehicles that automatically reach a single state of charge when plugged in. However for models with multiple charge settings, the situation gets complicated very quickly. Of course, these modes are often created in the software, meaning that a car's certified driving distance can change with just a few taps of the keyboard without the real world results owners might experience actually changing. By showing the test's effects on the certified range for the Tesla Model S, Nissan Leaf and Mercedes-Benz B-Class Electric Drive over the last few years, Green Car Reports makes a compelling argument that it's the evaluation that needs to change. Thankfully, it appears that the solution is a very simple one. Get the details here.

Mitsubishi cheated on Japanese fuel economy test since 1991

Mitsubishi now says that its cheating on Japanese fuel economy tests stretches as far back as 1991. The automaker has hired an independent panel of investigators to get to the bottom of what happened, and the company will give them three months to prepare a report about the deception. Mitsubishi's cheat involves how the company calculated driving resistance to determine fuel economy. In 1991, Japan's Road Transport Vehicle Act established a coasting test to establish the driving resistance, but Mitsubishi's engineers used their own "high-speed coasting test," according to its statement. In 2007, the company decided to only use the country's mandated evaluation, but the employees kept utilizing the high-speed test in the field. In the most recent scandal, workers selected low values for driving resistance from the results, which made the fuel economy look better. Mitsubishi's presented these details in a report to the Ministry of Land, Infrastructure, Transport, and Tourism. "We are currently investigating the reasoning behind each of the decisions," the company said in a statement. It also hired three former prosecutors to figure out why this happened for so long. At this time, Mitsubishi only confirms the incorrect figures for some of the company's minicars, but this investigation could discover more transgressions. This fiasco started when Nissan discovered fuel economy discrepancies in some of its Mitsubishi-made tiny kei-class cars in Japan. Mitsubishi came clean and admitted the problem affected about 625,000 vehicles in the country. Japanese media have alleged more vehicles have incorrect mileage, including the Outlander. The National Highway Traffic Safety Administration in the US has also requested data from the Japanese automaker to confirm similar deceptions didn't happen for vehicles here.
