Nissan Recalls More Than One Million Vehicles For Air Bags

Nissan is recalling just over one million cars, SUVs and vans because the front passenger air bags may not inflate in a crash. It's the company's second recall to fix the same problem. The recall affects the Altima midsize car, Leaf electric car, Pathfinder SUV and Sentra compact models from the 2013 and 2014 model years, as well as the NV200 Taxi van and Infiniti JX35 SUV from 2013. Also covered are the Infiniti QX60 and Q50 SUVs from 2014. In documents filed with the National Highway Traffic Safety Administration, Nissan says the vehicles' computer software may not detect an adult in the passenger seat. If that happens, the air bags won't inflate. Nissan will notify owners and dealers will update the software for free. The recall is expected to start in mid-April. Most of the vehicles were recalled in February of last year for a similar problem. Dealers replaced seat sensors, but Nissan said it continued to get consumer complaints and warranty claims in vehicles that had been repaired. Front passenger seats have sensors that determine the passenger's weight and turn off air bags off if a child is on board. The malfunctioning sensors can turn the air bags off even if an adult is in the seat. Nissan received three reports of air bags failing to inflate in a crash. Spokesman Steve Yeager said in an e-mail that he is not sure if anyone was hurt in those incidents. There have been no deaths due to the problem, he said. The recall affects almost 990,000 vehicles in the U.S., another 60,000 in Canada and small numbers in other countries, Yeager said. Related Gallery Nissan Searches For Identity In America

Basic Continuously Variable Transmission explained with Legos

In recent years, the search for better fuel efficiency and smoother shifting has produced automatic transmissions with double-digit gears. Alternatively, the same quest has boosted the popularity and usage of a different type of automatic transmission without any fixed gears, the continuously variable transmission, or CVT. YouTuber Sariel's Lego Workshop recently took the time to build a CVT demonstration model out of Legos to help explain how they work. Sariel begins by showing the model's input and output shafts that are parallel to each other. Each shaft has a cone attached to it, and they are inversely placed so that the large part of one cone is next to the small part of the other cone. The two cones are connected using a rounded rubber band.  By shifting the rubber band up and down the cones, the machine changes the effective ratio between the cones. So, a 1:4 ratio can be smoothly transitioned to 4:1. No clutch is required to operate the mechanism, and it eliminates hitches or pauses between gear changes. CVTs are also advantageous over 9- or 10-speed automatics in that they are far less complex and weigh less.  To demonstrate how the CVT operates in a vehicle, Sariel used a joke about Top Gear. The original Top Gear is represented by a faster-moving car that has the rubber band around the large part of the cone on the input shaft. Top Gear without former hosts Richard Hammond, Jeremy Clarkson, and James May is represented by a slow-moving car with the rubber band around the large part of the cone on the output shaft.  For an even more detailed explanation of how CVTs work — albeit one that doesn't involve toys — you can click here.

Ousted Renault CEO Bollore raised concerns over Ghosn investigation

PARIS — Renault's former chief executive Thierry Bollore, who was ousted in October, had sought to flag alleged conflicts of interest and governance problems at the company's Japanese alliance partner Nissan before his departure, Le Monde reported on Monday. Citing a letter from Oct. 7 addressed to Nissan's board, of which he was member, France's Le Monde newspaper said Bollore had raised questions over the firm's internal investigation surrounding former alliance boss Carlos Ghosn. Nissan and Renault were left reeling by Ghosn's arrest in Tokyo a year ago, on financial misconduct charges which he denies. They have since tried to reboot their strained partnership by revamping their management teams, including by purging them of Ghosn allies and removing people in top jobs at the time of the scandal. Bollore — who took a step up at the French carmaker when Ghosn left even though he was known for his close ties to the alliance founder — was eventually pushed out as Renault's CEO on Oct. 11, days after penning his letter. In comments sent to Reuters, Nissan spokeswoman Azusa Momose denied there were any irregularities in its internal investigation of Ghosn's affairs, and added that the company had reviewed its processes once again following Bollore's letter. "Nissan's independent directors confirmed that the investigation was properly conducted and could be relied on," Momose said. Nissan directors had discussed all the allegations raised by Bollore and the company "concluded that Bollore's concerns were not founded and were based for the most part on inaccurate information and speculation," she added. Bollore said in the letter that he was particularly concerned by the revelation that Nissan had a list of 80 managers implicated in financial dealings similar to the ones attributed to Ghosn. He also raised issues with the chain of command at Nissan, saying some key board members were sometimes kept in the dark on internal matters. Renault, which is still searching for a permanent replacement for Bollore as CEO, had no immediate comment. As well as changing its CEO, Nissan recently demoted senior vice president Hari Nada — a key whistleblower against Ghosn and whose role was also questioned in Bollore's letter — although its internal investigation had found no evidence against the executive.
