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 its longevity and durability, which they attribute to their reduced exposure to heat and friction, the business argues that CVTs are more trustworthy. 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 long is the lifespan of a Nissan CVT transmission?
New vehicles with CVTs should operate dependably for up to 100,000 miles on the market today. Overall dependability for the majority of cars will be lower than what is anticipated with a typical automatic or manual transmission.
However, exemplary owner maintenance can extend this prediction. In fact, some owners can obtain up to 200,000 trouble-free miles with a CVT provided they adhere to the factory-specified service intervals, apply the advised lubricant(s), and drive sensibly.
Do Nissan CVT transmissions have any issues?
The Nissan CVT, or continuously variable gearbox, was explicitly exploited as a “key selling feature for Nissan vehicles and was particularly marketed for its “smoothness,” according to a lawsuit brought by Christopher Gann against Nissan.
The Nissan lawsuit’s plaintiffs contend that anyone who have driven vehicles with CVT transmissions could disagree with that assertion. The main reason of worry with these allegedly defective gearboxes, 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.
Has Nissan made any improvements to their CVT?
I haven’t noticed any of the jerky shifts or chattering noises associated with the Nissan CVT in newer cars, and to be honest, I was quite happy with how the new Rogue used it.
Nissan did make an early attempt to soothe some of the concerns by increasing the warranty on the CVT for the model years 2003–2010 to 10 years/120 miles. But because it is 2021, that is plainly no longer true.
According to the JD Power Vehicle Dependability Studies we’ve looked at, Nissan has been improving the general reliability of its vehicles, although they still frequently fall short of the sector average. However, in our opinion, improvement is always ongoing. These studies focus on 3-year-old automobiles, therefore I’ll be very interested to see the results in 2024 since 2021 is a key year for Nissan with its new and updated models.
In response to our inquiry, Nissan provided the following comment regarding the existing CVT and any prospective buyer issues that might exist:
“Nissan continuously works to improve the quality of its CVT development and manufacturing, and we have faith in this technology. The latest generation Xtronic transmission, which offers good fuel efficiency, a responsive acceleration sensation, and a great driving experience, is featured in the all-new Sentra and all-new Rogue.
“Customers are encouraged to contact Nissan Consumer Affairs at 800-647-7261 or visit an authorized Nissan dealer if they have any queries or issues with their car.
This gives me reason to believe that the wait-and-see strategy will be successful, and I can vouch for the statement’s claims about “responsive acceleration” and “strong drive experience.”
Which automobile manufacturer offers the greatest CVT?
Having said that, not all CVTs are made equal; some are superior to others. These vehicles all feature CVTs.
Honda (Jazz, City, CR-V, Civic, HR-V, Odyssey), Subaru (Forester, WRX), and Toyota make some of the greatest CVT-type automatics we’ve tested so far.
Due in significant part to the use of a torque converter to transfer power to the driving wheels, the CVT-type automatic transmission that is installed in these cars offers quiet operation and smooth acceleration.
However, the CVT installed in the Subaru WRX is the one that has so far shocked us the most. You wouldn’t be aware that the car has a CVT transmission if we hadn’t told you.
Contrary to other CVTs we’ve experienced, the Subaru WRX launches itself with great vigor when asked for more, and the CVT matches the shifting characteristics of conventional automatics, increasing the whole experience.
Then there is Proton, which continues to insist on equipping its vehicles with CVTs that have a start-up clutch.
Punch-sourced CVT-style automatic transmissions are installed in Proton vehicles such the Exora, Iriz, and Persona.
While it may appear positive on paper, Proton vehicles with CVTs are jerky in traffic, loud, and unrefined—exactly the reverse of what a CVT should be.
At least Hyundai-sourced 4-speed torque converter automatic has been installed in place of the Saga’s CVT by Proton.
To be honest, Mitsubishi’s application of CVT in models like the Outlander and ASX may best be regarded as average, as it is frequently hesitant when the pedal is pressed all the way to the floor and is far from being as responsive as its competitors. At motorway speeds, the noise level is likewise fairly loud.
Nissan CVT failures: why?
Overheating could be one of the causes of all that shaking. Nissan has been charged with utilizing a transmission cooling system that is insufficient.
The CVT may rattle excessively as it warms up. Additionally, when it overheats, the automobile enters a fail-safe mode that restricts engine RPMs in an effort to prevent damage.
One of the objections in a Sentra Xtronic Lawsuit is that this can put drivers in a perilous situation.
A CVT’s lifespan is 200 000 miles.
There are numerous elements that affect a CVT’s durability. Although CVTs have been around for a long, they have only recently become dependable and reasonably priced. With routine maintenance, a CVT in a modern car should easily surpass 100,000 miles, while older CVTs might not survive as long.
Some automakers have stopped producing traditional automatic transmissions in favor of CVT technology, which costs a lot of money. The quality of CVTs has substantially stabilized over the past few years, enabling the majority of manufacturers to confidently make them without experiencing significant reliability concerns.
A decent CVT will last a very long time when taken care of. The owner’s handbook should be followed for routine maintenance.
How much does a Nissan CVT transmission replacement cost?
How much does repairing a CVT transmission cost? A CVT transmission typically costs between $3500 and $8000 to repair. The cost of a CVT varies depending on the type and model of the car; Subaru CVTs are more expensive than Nissan and Honda CVTs.
How can you make a Nissan CVT last longer?
You need to take a number of steps to ensure that your CVT-powered car lasts for a very long time. Like any other device you use, your car is prone to damage that, if neglected, might end up costing you a fortune. Although CVTs are relatively simple to use and have quite a following due to their effectiveness and functioning, they are also the most prone to failure if not properly maintained. Here are some suggestions for what you should do if you drive a vehicle with a CVT.
- Mudguard: In a car with a CVT transmission, the front mudguard plays a crucial role that is often overlooked. Make sure it’s positioned properly because it helps keep your CVT from accumulating dust.
- Adopt safe driving practices. Instead of using the throttle to support oneself while driving up a hill, press the brakes to prevent rolling backward. Then, after releasing the brake, hit the throttle again. Do not neutral stop your car, as you would with any other automatic transmission vehicle, since this could harm the CVT.
- It’s crucial that your car has enough fluid because overheating is a key risk with CVTs. However, you must make sure that the amount of fluid you add doesn’t exceed 75%, or around 3/4 of the reservoir. It must be exactly where the cross-hatch marks are. The problem will worsen if your transmission reservoir is overfilled. Your transmission will last longer if you have it serviced by a trained mechanic on a regular basis.
- Overloading: Avoid overloading your car because the added heat will put a lot of strain on the CVT belt. Keep to the recommended factory set weight for your car, if at all possible.
- Fluid replacement schedule: The fluid replacement schedule mostly depends on the type of car you drive, however most cars require a change after 100,000 miles. For a precise range, consult your owner’s manual or stop by a nearby auto repair shop.
CVT Transmission Trouble 101
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
Signs to Watch For
You don’t want to spend money on unneeded, expensive repairs if your automobile is in good condition. You also don’t want to disregard emerging problems because they can get worse quickly. How can you tell when it’s time to discuss your Nissan CVT with a qualified technician? A fluid leak can provide a hint. You might have to pay closer attention to see if this is happening. Contrary to the reddish hue of normal transmission fluid, CVT fluid is more translucent and has a slight golden or green tint. Other common symptoms include transmission slippage, a burning smell, power loss, or jerking. Bring your vehicle to Dave’s Ultimate Automotive if you observe them.
