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 durable is a Nissan CVT?
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.
Nissan CVT failures: why?
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 gets too hot, which results in a loss of power.
How can I tell if my Nissan CVT needs repair?
As a relatively new product on the market, CVTs can be highly challenging to diagnose and repair. Even though CVTs are a newer technology and are simpler in design and have fewer moving parts, our specialists are well suited to operate on your car because they have undergone comprehensive training specifically for CVTs.
The following are some CVT issues to watch out for:
- Engine Check Light On
- Transmission “jerking,” “slipping,” “grinding,” or “jumping” while the car is accelerating and changing gears
- Low or contaminated transmission fluid
- Overheating
- Driving when noisy
- When driving, some consumers experience “whining,” “clanging,” or “rattling” sounds, especially with Nissan CVTs.
- Changing gears at a high RPM
Has Nissan addressed the CVT issues?
According to The Car Guide, an expert contacted by the Automobile Protection Association (APA) asserted that technological adjustments made by Nissan in 2020 most likely resolved issues with the CVT.
We don’t yet know with certainty what those technological adjustments were. But critics have been praising the new 2022 Sentra, awarding it Best New Small Car Under $30,000 by Consumer Reports. This recognition would suggest that Nissan has solved its CVT issues.
This only applies to newer Sentra models made after 2020, though. Nissan may offer tailored extended transmission warranties for older cars on particular models and years with the CVT. Nissan provided a 10-year/120,000-mile guarantee, which is twice as long as the industry standard, for CVTs made between 2003 and 2010 (Automotive Addicts). Nissan’s Warranty page does not yet mention models manufactured between 2011 and 2017 as potentially being eligible for extended warranty coverage.
We advise contacting your neighborhood Nissan dealer for precise warranty information if you currently own a Nissan with a CVT manufactured between 2011 and 2019.
Which Nissan has issues with the CVT?
The above-mentioned defective CVT transmission has reportedly been found in the following Nissan models.
- Maxima Nissan 2016–2021
- Nissan Quest, 2015–2017
- Sentra, Nissan, 2018–2019
- Versa Note Nissan 2018-2019
- Altima Nissan 2017–2021
- Nissan Pathfinder, 2018–2021.
- Nissan Rogue, 2015–2017
- Nissan Murano, 2015–2021
It is obvious that this is a severe issue because there are numerous ongoing class-action lawsuits against the firm as a result of these defective transmissions.
Several class-action lawsuits and subsequent settlements have been obtained for the company’s factory-built vehicles from the preceding model year. The aforementioned comment led to an expanded warranty being offered to numerous customers for the Nissan CVT transmission. Despite associated payments and agreements, Nissan CVT transmission issues continue to prompt fresh lawsuits.
Compared to conventional gearboxes, continuously variable transmissions are allegedly more difficult to fix, don’t last as long, and are more prone to overheating. Nissan transmissions frequently experience problems.
Nissan’s CVT gearboxes have been known to have issues since 2009, but the firm hasn’t exactly taken quick action to fix the problem.
Lessees and owners of various vehicles have reported similar problems with Nissan CVTs, it has been observed. The following are only a handful of the common issues with Nissan’s transmission:
- breakdown of the transmission too soon
- Unusual changing sounds
- a revving engine
- sluggish acceleration
- excessive transmission heat
- burning odors
- Vehicle stuttering or hesitation
- trembling and swaying
- jerking and lurching
- Torque converter issue
- engine light that flashes
- poor fuel efficiency
The National Highway Traffic Safety Administration has received complaints about serious safety hazards brought on by these defective transmissions. According to one complaint, when driving on flat ground, a car may suddenly roll backward due to transmission issues.
Despite replacing four continuously variable gearboxes in less than two years, a second assessment found that Nissan vehicles had lost power in congested intersections and on motorways.
When acceleration problems arise on highways, at crossings, on freeway ramps, and at stops, drivers are more likely to cause a crash or rear-end collision when using a defective CVT transmission.
Are CVT engines as durable?
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 frequently should the fluid in a Nissan CVT transmission be changed?
How frequently does my Nissan need to exchange the CVT fluid? The continuously variable gearbox fluid should be changed approximately every 30,000 miles, according to Chapman Nissan.
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.
If properly maintained, a good CVT will last a very long period. The owner’s handbook should be followed for routine maintenance.
Is CVT preferable to automatic?
Benefits of CVT When compared to a conventional automatic, a CVT may offer a smoother driving experience depending on the car and the driver. One of the biggest benefits of having a CVT, according to Carfax, is that they frequently use less fuel than a standard automatic.
How can I make my 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.
- 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.
- 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.
- 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.
- 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.
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.
