Since Nissan’s initial global adoption of the continuously variable transmission in 1992, it has undergone steady research, augmentation, and improvement. The 2003 Nissan Murano was the first significant vehicle to use the XTRONIC CVT in the American market.
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.
Nissan, which made the conversion from traditional geared automatic transmissions to CVTs in the mid-2000s, was (perhaps) the first major automaker to do so.
Nissan has agreed to extend the warranty on some of its CVTs found in cars manufactured between 2003 and 2010 and 2012 and 2017.
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
Is the CVT in Nissan Reliable? Most likely not.
In 2002, Nissan proudly unveiled what they hailed as “the first CVT for passenger cars.” Mixed reviews were given to it, although that is to be anticipated for a first-generation product. The most frequently reported issues were slow acceleration, trembling or stuttering, running hot, and abrupt shutdown. Fortunately, Nissan would later resolve the majority of these worries.
The joke is on you. Now, 15 years later, Nissan customers continue to experience these issues. Nissan officials have reportedly been too preoccupied straightening out their cash piles to work out the kinks.
The future is today.
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 strives to improve the quality of CVT design and production, and we have faith in the capabilities of our CVT 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 urged to contact Nissan Consumer Affairs at 800-647-7261 or visit an authorized Nissan dealer if they have any questions or concerns about their vehicle.
This gives me reason to believe that the wait-and-see strategy will be successful, and I can personally attest to the statement’s claims about “responsive acceleration” and “strong drive experience.”
constantly changing transmission
An automated transmission that can vary smoothly across a continuous range of gear ratios is known as a continuously variable transmission (CVT). Other transmissions, in comparison, only offer a finite number of gear ratios in predetermined increments. With the right control, a CVT’s flexibility may enable the engine to run continuously at a set RPM even while the vehicle’s speed changes.
Nissan stopped utilizing CVT transmissions when?
The dated, current-generation Nissan Pathfinder is a three-row SUV that is pretty underwhelming. It lacks the nameplate’s tough history and handles more like a minivan than an off-road capable SUV.
It is therefore not surprising that Nissan intended to revamp this car for the upcoming model year. The company gave the 2022 Nissan Pathfinder an edgier look by drawing inspiration from the past. However, the mechanical parts of the SUV also brought an antiquated approach.
For the 2013 model year, the automaker gave the Pathfinder its first CVT, and the SUV has been using one ever since. Up until now, that is.
Nissan declared that the new nine-speed automatic transmission will be available on the 2022 Nissan Pathfinder. A front-wheel-drive system and a 3.5-liter engine with 284 horsepower are connected to this system. For individuals who desire extra traction or intend to use this SUV off-road, four-wheel drive is an option.
Depending on who you ask, switching from a CVT to an automatic transmission is either a step forward or backward. You must first comprehend the variations in these qualities before passing judgment.
Do all Nissan vehicles have a CVT?
Nissan was one of the first automakers to make a significant shift in favor of CVT gears. Because of this and their strong belief in the technology, most of their vehicles utilised CVTs starting in the 1990s and continuing through the 2000s and 2010s. The heavy-duty and high-performance Nissan vehicles are the only ones without CVTs. These include the Titan, Armada, 370Z, EV Leaf (an exception), GT-R, and 370Z. Their other vehicles, including the Altima, Pathfinder, Murano, Maxima, Rogue, Sentra, Versa, and others, all have CVTs as standard equipment. Nissan appears to be turning away from these though and toward more traditional automatics.
Nissan’s CVT transmission is produced by whom?
Because their only indication of driver participation is engine drone when the throttle is applied heavily, CVTs are our least preferred transmission type. Despite the broken heart, CVTs are gaining ground on manuals and traditional automatics. For instance, Toyota now offers a new belt-and-pulley transmission as standard on three-quarters of its Corolla lineup for 2014.
The CVT’s lack of drama is beloved by slow-laners. Put it in D, let the gas out, and rely on the flux capacitor in the engine compartment to act morally. In the event that one of these cruisers chooses to pass one of their own, a slight push of the accelerator offers additional thrust without even the slightest suggestion of shift shock.
Toyota, Subaru, Honda, Hyundai, and Audi all produce their own CVTs. Nissan holds a majority stake in JATCO, the company that provides Chrysler, GM, Mitsubishi, and Suzuki with 49% of the gear-free transmissions produced worldwide. Additionally, a JATCO-supplied CVT is available in roughly half of Nissan’s current U.S. models.
The advancements in CVT efficiency have sparked automakers’ interest. For the two eighth-generation JATCO gearboxes featured in the 2013 Altima, Nissan asserted a 40% decrease in friction. This resulted in a 10- to 15% gain in gas mileage when combined with other changes.
Toyota created an engine-driven oil pump with a second discharge port to reduce parasitic losses in its new “intelligent shifting” CVT. The transmission lubrication is done through the low-pressure outlet. The hydraulic pressure required to tightly clamp the steel belt between the driven and driving pulley halves is provided by a variable high-pressure port. This clever pump setup reduces power usage while preventing slippage. In addition, the CVT in the Corolla S includes seven synthetic “gears,” a performance mode, and paddle shifters to address two common complaints: the rubber-band effect and the lack of driver participation.
The second area where CVTs outperform other gearboxes is in ratio spread, or the ratio of the lowest driving ratio to the highest. The Nissan Altima’s 7.0:1 ratio spread may not seem spectacular compared to the 9.8:1 ratio spread in ZF’s new nine-speed automatic, but it was a 17-percent improvement over JATCO’s seventh-generation CVT. JATCO engineers acknowledge that wider ratios are both theoretically possible and a major priority in their future designs, but they won’t say how much the gap can be widened.
The first hybrid SUVs with belt-type CVTs have just been produced thanks to a partnership between JATCO and Nissan. A supercharged 2.5-liter four-cylinder engine and an AC motor that provide a combined 250 horsepower and either front-wheel drive or all-wheel drive power the 2014 Nissan Pathfinder and Infiniti QX60.
Pure electric vehicles have so far avoided any form of drive-ratio change, but don’t be shocked if you see a future Nissan Leaf with a JATCO-supplied CVT. The Leaf’s acceleration, cruising manner, and range might all be improved by adding a transmission. When braking and decelerating, using low drive ratios will considerably increase the amount of energy that is returned to the battery through regeneration. The friction binders should only be used in emergency stops, therefore brake pads should last the entire life of the vehicle.
This is not meant to imply that CVTs are about to become widely used. And our objects of love, such as Corvettes, Porsches, and similar vehicles, are out of their reach. But be prepared for your neighbor to boast about his brand-new, non-shifting transmission.

- 2019-2022 Renault Rogue
- Nissan Versa, 2018–2012
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.
