2013 Nissan Pathfinder drivers reporting loss of power, 'shuddering' [w/video]

No one appears to have a handle on the numbers, but more than a few owners are registering the same complaint about the CVT-equipped 2013 Nissan Pathfinder: that it "shudders" and loses power when accelerating from a standstill or at low speeds. According to posters at places like Pathfinder Talk, Edmunds, Auto Recalls for Consumers and About Automobile, it happens between about 20 to 40 miles per hour, the sensation is described as being like "driving over a rumble strip" and the power loss occurs for about three to four seconds.
ABC 13 in Houston rode with Pathfinder owner Marlise Holzworth to experience the issue, Holzworth saying that it feels like her vehicle is about to stop when the shudder occurs. Nissan responded to the report, saying that, "A new part has been developed for 2013 Pathfinders that exhibit symptoms similar to those Ms. Holzworth describes. The necessary part should be available at Nissan dealers in June."
Likewise, according to a post on the PathfinderTalk forum, user Krsin97 was informed by a Nissan engineer in April that "[We] are aware of the problem and Nissan is working on update that will come out at the end of June to eliminate the problem."

Nissan alters all CVTs to act less like a stretched rubberband

Among automotive enthusiasts, no one seems to hold a neutral opinion when it comes to continuously variable transmissions. CVTs are either praised for their ability to boost fuel economy or chided for their occasionally poor driving dynamics. Nissan is among the masters of these un-shifting gearboxes in the US, and it uses them in many vehicles in its lineup. However, for the 2015 model year, several models are getting a software update to make their CVTs a bit more like a conventional automatic.
To give drivers the option of feeling gearshifts while on the road, Nissan is adding its D-Step Shift Logic feature to the CVTs in multiple vehicles. Steve Powers, Nissan's senior manager of powertrain performance, told Autoblog the system forces the transmission to "hold a ratio and then shift" to simulate the way that a traditional automatic would. It's simply a change in software, but the company "can't do it to older CVTs," he said, because it would require changes to transmission logic, as well. According to Automotive News, the upgrade is coming to the 2015 Versa, Versa Note (pictured above), Sentra, V6-equipped Altima, Pathfinder and Quest. "We're rolling it out to all programs," said Powers.
Interestingly, buyer perception appears to be pushing the upgrade. John Curl, a Nissan North America regional product manager, told Automotive News that the decision to add the tech partially comes because some owners are bothered that the CVTs aren't changing gears. According to Powers, D-Step "avoids the rubber band feel," that many drivers didn't like. The different sensation of these transmissions seems like something consumers would notice during the test drive, or that the salesperson would inform them about. The same issue cropped up last year when the company was facing customer satisfaction problems among new buyers customers' unfamiliarity with the gearboxes.

Next Nissan GT-R to take cues from GT-R LM Nismo Le Mans entry

For those wondering why Nissan named its coming Le Mans Prototype the GT-R LM Nismo, colliding the two worlds of sports car and prototype racing, an article in Autocar might have the answer. The deeper union is explained by saying that the next-generation GT-R will use "hybrid technology that will closely align it" with the GT-R LM Nismo.
The point could be further driven home by the fact that the GT-R LM Nismo will begin its FIA endurance racing campaign next year, and the next GT-R is due to debut next year as a 2016 model. The expectation is that it will use a hybrid system possibly dubbed R-Hybrid and perhaps developed by Williams. Just like performance car makers Ferrari and Audi, Nissan wants its racing efforts to pay off with road car technology, company vice president Andy Palmer saying they "want to link technological linkages between future evolutions of the GT-R and evolutions of what we do in LMP1, and the two do go in both directions."
The bigger question is, with the GT-R getting hybrid assistance, will it also get the weight gain that usually comes with it? Enthusiasts would love to see the trend reversed, especially on a car that's already no lightweight.
