NHTSA opens investigation into Nissan's handling of airbag recall

In March of 2014, Nissan recalled eight models among its Nissan and Infiniti brands, totaling more than one million vehicles, over faulty occupant classification system software controlling the passenger airbag. The company discovered a variety of factors that would interfere with the system's ability to detect an adult passenger in the shotgun seat, resulting in an illuminated warning on on the dashboard and the passenger airbag not deploying in an accident. Yet 124 complaints submitted to the National Highway Traffic Safety Administration since the recall allege that the dealer-installed fix hasn't actually fixed the problem; some consumers say the problem persists after multiple trips to the dealer. The Detroit News reports that NHTSA is opening an investigation into the matter to determine whether a new recall is needed. The occupant sensor has been a bugbear for Nissan over the past couple of years; a much smaller recall for the issue in 2013 covered five of the eight vehicles that were recalled in 2014, and that earlier recall also continued to generate complaints after the issue had supposedly been fixed. At the same time, the company learned that in two instances there was another twist, where the dashboard warning wasn't illuminated but the passenger airbag still didn't go off in an accident. Nissan isn't alone, though, with airbag recalls on a steep upswing across the industry even before the Takata debacle.

DC fast charging not as damaging to EV batteries as expected

As convenient as DC fast charging is, there have been lots of warnings that repeated dumping of so many electrons into an electric vehicle's battery pack in such a short time would reduce the battery's life. While everyone agrees that DC fast charging does have some effect on battery life, it may not be as bad as previously expected. Over on SimanaitisSays, Dennis Simanaitis, writes about a recent presentation by Matt Shirk of the Idaho National Laboratory (INL) called DC Fast, Wireless, And Conductive Charging Evaluation Projects (PDF) that describes an ongoing test of four 2012 Nissan Leaf EVs that are being charged in two pairs of two. One pair only recharges from 50-kW DC fast chargers, which the other two sip from 3.3-kW Level 2 chargers exclusively. Otherwise, the cars are operated pretty much the same: climate is automatically set to 72 degrees, are driven on public roads around Phoenix, AZ and have the same set of dedicated drivers is rotated through the four cars. "Degradation depends more on the miles traveled than on the nature of recharging." What's most interesting are the charts on page seven of Shirk's presentation (click the image above to enlarge), which show the energy capacity of each of the four vehicles. When they were new, the four batteries were each tested to measure their energy capacity and given a 0 capacity loss baseline. They were then tested at 10,000, 20,000, 30,000 and 40,000 miles, and at each point, the DC-only EVs had roughly the same amount of battery loss as the Level 2 test subjects. The DC cars did lose a bit more at each test, but only around a 25-percent overall loss after 40k, compared to 23 percent for the Level 2 cars. Simanaitis' takeaway is that, "INL data suggest that the amount of degradation depends more on the miles traveled than on the nature of recharging." The tests are part of the INLs' Advanced Vehicle Testing Activity work and a final report is forthcoming. These initial numbers from IPL do mesh with other research into DC fast charging, though. Mitsubishi said daily fast charging wouldn't really hurt the battery in the i-MiEV and MIT tests of a Fisker Karma battery showed just 10-percent loss over 1,500 rapid charge-discharge cycles.

Renault to alert prosecutors about Carlos Ghosn's wedding costs

PARIS — Renault has found evidence that it paid part of Carlos Ghosn's wedding costs and is preparing to turn the investigation over to prosecutors, two weeks after the French carmaker's scandal-hit chairman and chief executive was forced out. An internal probe established that a 2016 sponsorship deal with the Chateau de Versailles included a 50,000 euro ($57,000) personal benefit to Ghosn, the carmaker said on Thursday, confirming a report in Le Figaro. The carmaker replaced Ghosn on Jan. 24, more than two months after his arrest in Japan over allegations of financial misconduct uncovered by Renault's Japanese affiliate Nissan, which he also chaired. Renault began its own examination of payments to Ghosn within days of his detention but had not flagged any irregularities until now. Renault has discovered that "Mr Ghosn was accorded a personal benefit valued at 50,000 euros under the terms of a sponsorship contract with the Chateau de Versailles," the company said in a statement on Thursday. "Renault has decided to bring these findings to the attention of the judicial authorities." The office of Ghosn's Japanese lawyer Motonari Otsuru did not immediately respond to a request for comment. Ghosn remains in detention in Tokyo with limited opportunity to respond publicly to allegations against him. Renault had agreed before the wedding to sponsor 2.3 million euros of Versailles renovations in return for a credit granting the carmaker services from the chateau worth 25 percent of that amount, or 575,000 euros, a person with knowledge of the matter told Reuters. Le Figaro reported that the chateau allowed Ghosn to host his wedding reception on its grounds in exchange for Renault's donations to the Versailles estate, resplendent home to France's last kings. The rental fee was deducted from Renault's credit for use of the Grand Trianon at Versailles on Oct. 8, 2016, when Ghosn and his second wife Carole hosted their wedding reception at the 17th-century palace, the source said. The event had already attracted public attention for its opulence and Marie Antoinette-themed costumes. The Renault board was informed about the discovery on Wednesday, as reported by Le Figaro, the source added. Earnings/Financials Government/Legal Mitsubishi Nissan Renault renault-nissan
