The idea behind CVTs is easy to understand: a heavy-duty drive belt or chain runs within a grooved pulley system with hydraulic actuators allowing the affective ratio to be infinitely varied within a range of ratios, seamlessly. But the reviews from actual owners are a lot less rosy. Low speed acceleration is a particular trouble-spot for this CVT.
According to owners, their vehicles will shutter and shake while getting up to speed. Run away from this car! My transmission was reprogrammed at 12k miles. Drove well, no issues and all scheduled maintenance done regularly at the dealer.
At 65k transmission started shuddering and then vehicle would stall and die in traffic, very dangerous. Vehicle was sent into dealership three separate times, for engine pulley, reprogramming, completely new ECM.
Each time the car ran worse. The vehicle is the worst I have ever owned, and would never buy another Nissan due to this. The TSB, which was written for the Murano, tells mechanics to check for these conditions if an owner complains about hesitations:. One of the reasons for all that shaking might be an overheating. Nissan has been accused of using an inadequate cooling system for their transmission.
As the CVT heats up it can vibrate excessively. And when it overheats it sends the car into fail-safe mode which limits engine RPMs as it tries to prevent damage. This can leave drivers in a dangerous position, and is one of the complaints in a Sentra Xtronic Lawsuit. CVTs are, by design, going to feel different when you cram the accelerator to the floor. While a geared transmission will typically burst off the line, a CVT has a much smoother and slower increase to maximum power.
But some say the CVT's sluggishness goes too far. Some go so far as to call it a safety hazard when trying to merge onto a busy road. The car has had the same problem for several years. CVT whine is a common problem and not unique to Nissan vehicles.
It got worse every summer and even would suddenly stop accelerating. I took the car into the dealer for 3 summers in a row. The first two summers they basically told me I was crazy because they could not reproduce the issue. In the case of Kobe Falco, et. Nissan North America, Inc. The technology delivers seamless performance without shift changes when accelerating and decelerating.
Further, the optimal transmission control makes for a drive that is intuitive, with a superb driving performance.
CVT adjusts the width of two pulleys and changes the arc radius of the steel belt running between them in order to control the transmission gear ratio. In the illustration above, the arc radius of the belt for the engine shaft pulley gets narrower. That would be Armada , Pathfinder and later , Frontier and Titan. However, as the sheer volume of comments on my social posts suggest, the Nissan CVT has an incredibly bad reputation.
Looking at sites like CarComplaints. In fact, some of those vehicles, such as the Altima , get a special badge on CarComplaints. It looks like the bulk of the lawsuits center around models, with the primary complaints coming from Altima, Pathfinder and Rogue. When we did a quick search for lawsuits pertaining to the Nissan CVT, the newest model year engaged in litigation is the model year.
Part of that could be the continuous improvements Nissan is making to the CVT. However, our view: Continuous improvement is, well, continuous. It uses a heavy-duty drive belt or sometimes chain that operates within a hydraulically triggered, variable pulley system. It moves gears up or down in a smooth motion resulting in stronger acceleration and increased fuel economy.
Nissan states that their XTronic CVT offers rapid, seamless acceleration, significant improvement in fuel economy, and a lighter, more compact unit.
