Nissan recalls 3,065 Pathfinders for transmission fluid leak

Nissan is recalling 3,065 units of the 2013 Pathfinder equipped with the CVT, due to a potential transmission fluid leak. On crossovers built from April 18, 2012 to October 3,2012 "inadequate clamping force" on the hose connected to the internal oil cooler can cause the hose to come loose and let fluid escape. A severe loss of fluid can cause the transmission to stop working properly.
The recall is the result of a safety investigation begun last September, when it was thought a recall could involve 110,000 units of the Pathfinder and Infiniti JX35. Asked for comment about how such a large number of vehicles potentially involved could end up with just 3,065 being recalled, Nissan rep Steve Yaeger told Autoblog that Nissan initiated a service campaign for the issue last year - a service campaign notifies owners to take their vehicles to the dealer for repair of "what is generally not a safety issue" - and that there was a "production improvement" that addressed the clamping issue. The service campaign included the vehicles being recalled, but the recall is limited to just those vehicles that were built before the production-line fix.
Nissan will begin informing affected owners next month, at which time owners can take their vehicles to dealers to have the hose clamp repaired. The press release below from the National Highway Traffic Safety Administration has more information.

Japanese automakers will seriously subsidize hydrogen fuel stations

Fresh off the announcement of the EPA-rated fuel economy and range figures for the Toyota Mirai, three of Japan's major automakers are throwing their weight behind hydrogen on the other side of the Pacific. Toyota, Nissan, and Honda are detailing their partnership in Japan to subsidize the creation of an expanded FCV refueling infrastructure there in the coming years. The plan could provide a much-needed boost for goals that are already looking to miss their targets. The partnership, which is called the Joint Hydrogen Infrastructure Support Project, is subsidizing a third of the annual operating expenses up to a maximum of 11 million yen ($90,000) for any hydrogen refueling station that applies and is accepted into the program. For now, the automakers plan to keep this running through around 2020. Toyota senior managing officer Kiyotaka Ise tells Bloomberg the whole thing over that time is expected to cost 5 billion to 6 billion yen ($40.5 million to $49 million). In addition to the money, the companies are trying to raise awareness about the alternative fuel to build popularity. Japan has been pushing extremely hard to build the FCV market there for quite some time by subsidizing both the models and building refueling stations for them. By the 2020 Olympics, the country's goal is to have 6,000 fuel cell vehicles on the roads and possibly even 100,000 of them by 2025. The cars to fulfill these lofty hopes are just gaining steam, though. For example, the Mirai is already experiencing high demand, and Honda is set to bring its new challenger in 2016. This announcement says Nissan is aiming a potential entry for 2017, as well. According to Bloomberg, the fuel cell industry in Japan is forecasted to balloon from 400 million yen (3.3 million) in the current fiscal year to 100 billion ($813 million) by 2025. Toyota, Nissan, and Honda Agree on Details of Joint Support for Hydrogen Infrastructure Development Toyota Motor Corporation, Nissan Motor Co., Ltd., and Honda Motor Co., Ltd. have agreed on key details regarding a new joint support project for the development of hydrogen station infrastructure in Japan. In addition to partially covering the operating costs of hydrogen stations, the three automakers have also agreed to help infrastructure companies deliver the best possible customer service and create a convenient, hassle-free refueling network for owners of fuel cell vehicles (FCVs).

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.
