The CVT is an automatic transmission that runs a steel belt between two pulleys. The diameter of the “drive pulley,” which transmits torque from the engine, and the “driven pulley,” which transmits torque to the wheels, are simultaneously adjusted by the CVT to continuously modify its gear ratios.

Nissan CVT transmissions: Are they dependable? Customers Suggest Otherwise!
The continuously variable transmission (CVT), an automatic transmission that uses computer software to control the ratio of gears chosen for the optimal driving experience, was invented by Nissan and is frequently credited as its inventor. The firm started working on its CVT in 1992, but didn’t start using it on a regular basis until around 2003. Nissan’s CVT transmission is merely impeding the company’s potential to expand and advance, even though the CVT is a brilliant milestone in the optimization of modern automobiles.
Nissan customers are unable to benefit from the device’s ongoing improvements since they are constantly need to deal with the CVT’s negative impacts, despite its numerous advancements. Due to their endurance and durability—which they attribute to their reduced exposure to heat and friction—the business notes that CVTs are more reliable. Nissan’s confidence in the dependability of its CVTs has, unfortunately for many customers, been disproved by this component’s flaws, which have subjected them to higher temperatures and friction than they were intended to withstand.
How does the CVT in a Nissan vehicle operate?
Nissan uses a belt and pulley arrangement for its CVT transmission. This belt connects a pair of movable pulleys and is comprised of metal links. This mechanism modifies the transmission’s gear ratio. Theoretically, CVT transmissions have “infinite” gear ratios. In this manner, a driver is spared from having to “shift” gears in response to changes in the driving environment or when accelerating or decelerating.
101 CVT Transmission Issues
Let’s start by discussing the CVT overview. Continuously Variable Transmission is what it stands for. Once activated, it operates similarly to a conventional automatic transmission, requiring no further intervention from the driver. But the CVT has no gears. It operates with a dual pulley system. A smoother transition between lower and higher speeds as well as improved fuel efficiency are the goals of this more recent transmission. Although this makes sense in theory, there have been some issues with Nissan applications. The problems were typically reported between 2012/2013 and 2018. When Nissan first started utilizing this transmission in 2003 and during the generation of CVTs from 2007 to 2012, there were a few issues. The Murano, Sentra, Altima, Rogue, Versa, and Versa Note are specific models.
Although anything might go wrong for any manufacturer, Nissan’s issue is most likely the result of overheating. Failure to adequately cool the transmission might hasten the deterioration of the transmission. Additionally, for these specific models, the automobile detects heat distress and lowers its RPMs to prevent damage, which naturally affects horsepower. Nissan’s extended warranty may be useful for a while if your vehicle is affected and/or recalled. Transmission coverage was extended for some vehicles from 5 years/60,000 miles to 10 years/120,000 miles. Nevertheless, the warranty will eventually expire, and you might discover that your car needs, which
A little history
A CVT is a single-speed or stepless gearbox that uses a pulley system to shift gear ratios, in case you are unfamiliar with the word. There are several (countless) films and animations that demonstrate how it works; if you want to see it in action, just search for it on Google, but I felt this one did a decent job of explaining how a CVT works without being too technical.
Nissan’s Xtronic CVT, which made its debut in 2011, is currently in its third iteration. But this CVT has actually been around for a little little longer. Although it made its debut internationally in 1992, the U.S. didn’t see it until the 2003 Murano, according to Nissan’s customer website. Since then, the range has made extensive use of it, with examples of it being used in the Altima, Maxima, Kicks, Rogue, Rogue Sport, Murano, Versa, and Sentra. Along with the defunct Juke and Versa Note, it was also utilized in the Pathfinder of the prior generation, which dates from 2021 and earlier.
Which automobiles lack it, maybe, might be a better query? Armada, Pathfinder (2022 and later), Frontier, and Titan fall under this category.
Nissan does not refer to the CVT as reliable in the FAQ at the end of its CVT primer, but it does note that it has fewer moving components, which lowers friction and heat. It “may” survive longer as a result than a conventional transmission.
Nissan CVT transmission failures have a cause.
Nissan CVTs are notorious for overheating, especially while going up a steep incline or for an extended period of time at highway speeds. The transmission frequently enters a fail-safe or “limp” mode when it overheats, which results in a lack of power.
Do Nissan CVT transmissions have any issues?
The Nissan CVT, or continuously variable gearbox, was especially promoted as a “key selling point” for Nissan vehicles and was praised for its “smoothness,” according to a lawsuit Christopher Gann filed against Nissan.
The Nissan lawsuit’s plaintiffs contend that anyone who have driven vehicles with CVT transmissions could disagree with that assertion. The biggest issue with these allegedly defective transmissions, according to the plaintiffs, is “sudden, unexpected shaking and violent jerking.”
Nissan owners with vehicles with model years in the range of 2013 and 2020 have complained to the National Highway Traffic Safety Administration (NHTSA) alleging that CVT transmission flaws have harmed their vehicles.
It has been reported by drivers that their transmissions jerk, stall, shiver, hesitate, or even fail prematurely. Some drivers claim that an unexpected engine power surge occurs after these accidents. Many drivers have reported that as they try to accelerate, these CVT problems start to occur.
These types of car flaws can be risky because they could come as a surprise to the driver and make them lose control.
This effect is thought to be brought on by problems with the transmission, hose leaks and failures, CVT transmission error messages, and a loss of power.
How long is the lifespan of a Nissan CVT transmission?
The lifespan of a CVT transmission is the same as that of a conventional automatic transmission, and they are built to last the entire life of the car. The lifespan of a normal CVT is at least 100,000 kilometers. Some vehicles, like the Toyota Prius, frequently have a lifespan of far over 300,000 kilometers. Some brands, like other automotive parts, last longer than others when maintained properly.
How do I reset the CVT in my Nissan?
For comparable vehicles, the Nissan XTRONIC CVT transmission can significantly increase fuel efficiency over earlier CVT transmissions by up to 10% or more. The snappy and potent acceleration is provided by the Adaptive Shift Control, which adjusts shifting patterns to match each driver’s preferences and the road. The engine’s speed-dependent rev limit is maintained by the control system, which also works to reduce noise.
The clutch point relearn operation must be carried out if the XTRONIC CVT has been serviced or if components like the valve body have been replaced. Perform this manual process if the scan tool does not offer this option. Before starting this procedure, clear all previously stored trouble codes.
1. Turn on the engine and let the transmission warm up to 122 degrees Fahrenheit (50oC). To check the transmission temperature, use a scan tool.
2. Switch off the air conditioning.
3. Place the gear selector in Park, turn off the ignition, and then wait five seconds.
4. After starting the engine, let it idle for five seconds.
5. After waiting for 30 seconds, turn off the ignition.
6. Complete two more cycles of steps 4 and 5 for a total of three cycles.
Start the engine again.
8. Let the engine run at a standstill for 30 seconds.
9. Put the “D” position on the shift selector.
10. Use a low throttle to accelerate the car from 0 mph (0 km/h) to 40 mph (65 km/h). roughly 1/8 of the throttle.
11. Slow down the car without applying the brakes to 18 mph (30 km/h) or less.
12. Bring the car to a complete stop and set the gear selector to Park.
13. Exit the vehicle and wait five seconds.
14. Start up the vehicle.
15. To complete five cycles, carry out steps 13 and 14 four times each.
16. Place the “D” position on the shift selector.
17. Use a low throttle to accelerate the car from 0 mph (0 km/h) to 28 mph (45 km/h). roughly 1/8 of the throttle.
18. Come to a complete stop and place the park position on the gear selector.
19. Switch off the ignition and give it five seconds.
20. Let the engine start.
21. Complete steps 19 and 20 a total of four times for five cycles.
Drive the car to make sure the CVT transmission is working properly.
Note: If this retrain method is not completed properly, shifts will be quite hard.
Is the Nissan CVT transmission subject to a recall?
Nissan North America and customers of certain Nissan cars with faulty continuously variable gearboxes have achieved a class action settlement (CVTs).
According to the most recent case, the Japanese carmaker purposely sold cars with faulty CVT transmissions. Nissan entered into a deal to address some accusations of defective transmissions in which it agreed to pay approximately $277 million. The 2022 Nissan CVT settlement covers the following Nissan models:
- 2018-present Nissan Rogue
- Nissan Pathfinder, from 2015 to 2018.
- Infiniti QX60, 2015–2018
In the most recent class action case against Nissan that was settled, it was claimed that a number of the automaker’s vehicles had defective CVTs. According to a number of drivers, their vehicles’ transmission and other lemon problems started in as low as 20,000 miles.
Three distinct class action lawsuits were resolved with Nissan North America in 2020. Similar allegations, namely that the manufacturer knowingly sold automobiles with defective CVT transmission systems, served as the basis for these lawsuits.
All three of the earlier claims, which involved the following Nissan vehicles, resulted in class action settlements.
- Versa 2012-2017 Nissan
- Nissan Versa Note, 2014–2017
- Nissan Sentra, from 2013 to 2017.
- Nissan Altima from 2013 to 2016.
- Nissan Juke, from 2013 to 2017.
