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.

Nissan expands, shrinks Leaf recall for missing weld points

Chalk this one up to the quirks of the English language. The other day, we had a post on the recall of a small number of 2014 Nissan Leaf EVs that were missing weld spots. The official bulletin from the National Highway Traffic Safety Administration said that "any vehicle missing welds will be replaced, free of charge." We read that as saying that the welds would be replaced, but in fact it's the cars themselves that will be swapped out. NHTSA said that 211 Leafs were potentially involved in this recall, but we heard from Brian Brockman, Nissan's senior manager of corporate communications, that Nissan is actually looking at, "approximately 276" vehicles. More importantly, Brockman clarified that, "If a vehicle is found to be missing the welds, the entire vehicle will be replaced." NHTSA documents on Inside EVs show that Nissan expects just 0.65 percent of those Leafs will need to be replaced. Brockman wouldn't say exactly how many cars Nissan thinks are affected, but 0.65 percent of 276 is just 1.8 vehicles. Brockman did say that, "you'd be correct to say that we expect the number to be very low." Read Nissan's full statement below. Nissan is conducting a Voluntary Recall Campaign on approximately 276 MY2014 LEAF vehicles to inspect the front member assembly welds. Due to an isolated supplier process error that has been corrected, a small number of vehicles within a subset of MY2014 LEAF vehicles manufactured during a two-week period may have front frame member assembly components that were not welded to proper specification. This can affect crash performance. Within the next few weeks, affected LEAF owners will be asked to bring their vehicle to a certified Nissan LEAF dealer for an inspection. If the vehicle is determined to be affected, Nissan will provide owners with a brand new replacement vehicle at no additional cost. A loaner vehicle will be provided during the vehicle exchange process. It is anticipated that only a handful of retailed vehicles are affected by the weld issue and require vehicle replacement. Nissan is committed to a high level of customer service and satisfaction and is working with its dealers to provide an outstanding ownership experience to Nissan LEAF owners.

Nissan seeks tech tie-up without Renault as alliance nears end of road

Nissan is developing growth plans in areas such as software and electric vehicles (EVs) independent of Renault SA as the automakers work to finalize terms of a sharply limited alliance, said seven people with knowledge of the matter. Japan's third-biggest automaker by sales is seeking a partner outside the auto industry to develop software that connects vehicles to cloud-based services, two people involved in discussions said, without elaborating on candidates. That would address a relative weakness for Nissan as it tries to make cars "smarter and more connected," one of the people said. It is also working on an expanded strategy for all-battery and plug-in EVs for North American and Asian markets that will be for Nissan alone, they said. The revelations come as the alliance oversight board met this week to discuss a rebalance that will see Renault cut its stake in Nissan to 15% from 43% — matching the size of Nissan's stake in Renault — and Nissan gain reciprocal voting rights. Under the deal, to be finalized by mid-year, Nissan will also invest in the French automaker's new Ampere EV business. Imbalance had long riled Nissan executives who complained Renault did not pay its fair share of costs for innovation and development. Nissan's emerging strategy reflects a belief within the automaker that the 23-year-old alliance has run its course for many of the biggest challenges it faces, the people said. While Nissan sees continued savings in shared parts procurement with Renault, it has no plan to provide engineering support to Ampere, said two of the people, who all asked not to be identified because talks between the pair are ongoing. It also has no plan to provide its e-Power hybrid technology to a gasoline powertrain-focused joint venture Renault has with China's Zhejiang Geely Holding Group Co Ltd and Saudi Aramco Base Oil Co JSC, two of the people said. GOING SOLO Such go-it-alone thinking is shaping a longer-term plan that could be announced by year-end focusing on improved operational performance, electrification and software allowing self-driving and other "connected car" features, one of the people said. "Even if Renault gets something from Nissan, benefits moving in the other direction are hard," a second person with knowledge of Nissan's stance said.
