Nissan has been manufacturing quality cars for many years. One of their most desirable features is Continuously Variable Transmission (CVT). This type of transmission has been used in Nissan vehicles for a while now, and it is becoming more popular due to its fuel efficiency and smooth driving experience. However, there have been some reported Nissan CVT transmission problems that have left some Nissan owners frustrated. In this article, we will discuss the common causes of Nissan CVT transmission problems and their solutions.
What is a CVT?
Before we dive into the common problems associated with Nissan CVT transmissions, let us first define what a CVT is. A Continuously Variable Transmission (CVT) is a type of automatic transmission that uses a pulley system instead of gears to provide a smooth and efficient driving experience. The pulley system allows the car to change seamlessly through an infinite number of gear ratios, unlike traditional automatic transmissions that have a fixed number of gears.
Which Nissan Cars Have CVT Problems?
Several Nissan models have been reported to have CVT problems, including:
- Nissan Sentra
- Nissan Altima
- Nissan Versa
- Nissan Juke
- Nissan Rogue
- Nissan Murano
- Nissan Pathfinder
- Nissan Qashqai
- Nissan Navara
- Nissan Micra
Common Symptoms Of CVT Transmission Problems
Jerking or Shuddering during Acceleration: One of the most common symptoms of Nissan CVT transmission problems is a jerking or shuddering sensation during acceleration. This can be caused by issues with the transmission fluid or other components.
Delayed Shifting: Another common symptom of Nissan CVT transmission problems is delayed shifting. This can occur when the transmission fails to shift gears at the appropriate time, leading to a loss of power or acceleration.
High-Pitched Whining Noise: A high-pitched whining noise coming from the engine or transmission area can be a sign of Nissan CVT transmission problems. This can be caused by issues with the transmission fluid or other components.
Overheating: Overheating is a common problem with Nissan CVT transmissions, which can cause the transmission to fail or even catch fire. Symptoms of overheating can include a burning smell, smoke, or warning lights on the dashboard.
Slipping Gears: Another symptom of Nissan CVT transmission problems is slipping gears. This can occur when the transmission fails to engage a gear or slips out of gear while driving.
Loss of Power: Nissan CVT transmission problems can also cause a loss of power or acceleration, making it difficult to drive your vehicle at normal speeds.
Causes Of CVT Transmission Problems
Overheating
Overheating is one of the most common causes of Nissan CVT transmission problems. The CVT transmission relies heavily on a transmission fluid to keep the transmission running smoothly. If the transmission fluid gets too hot, it can start to break down, causing the transmission to slip, shudder, or fail altogether.
The most common cause of overheating is towing or hauling heavy loads, which can put a lot of stress on the transmission. Other causes of overheating include driving in stop-and-go traffic or on steep inclines for extended periods. If your Nissan CVT transmission is overheating, you should have it checked by a certified mechanic as soon as possible.
Lack of Maintenance
Another common cause of Nissan CVT transmission problems is a lack of maintenance. Like all car components, the CVT transmission requires regular maintenance to keep it running smoothly. This includes regular oil changes, filter replacements, and fluid flushes.
If you neglect your Nissan’s CVT transmission, you may start to notice problems like slipping, shuddering, or a loss of power. To avoid these problems, be sure to follow the manufacturer’s recommended maintenance schedule for your car.
Sensor Issues
Modern cars rely heavily on sensors to monitor various components and systems. If the sensors fail, it can cause a lot of problems, including issues with the CVT transmission.
One common sensor issue is a faulty speed sensor, which can cause the transmission to shift erratically or fail to shift at all. Another common sensor issue is a faulty pressure sensor, which can cause the transmission to slip, shudder, or fail altogether.
If you suspect a sensor issue with your Nissan CVT transmission, you should have it checked by a certified mechanic as soon as possible.
Design Flaws
While Nissan’s CVT transmission has many benefits, it also has some design flaws that can cause problems. Among these design flaws is the lack of a transmission cooler. This can cause the transmission to overheat, leading to problems like slipping, shuddering, or failure.
Another design flaw is the use of a push belt instead of a traditional steel belt. Push belts are more prone to wear and tear, which can cause problems like slipping or shuddering.
If you suspect a design flaw is causing problems with your Nissan CVT transmission, you should contact a certified mechanic or your local Nissan dealer to discuss your options. If your vehicle is under 3 years old it should be covered by a manufacturers warranty.
Solutions to Nissan CVT Transmission Problems
Regular Maintenance
As mentioned earlier, regular maintenance is crucial to keeping your Nissan’s CVT transmission running smoothly. This includes regular oil changes, filter replacements, and fluid flushes.
Be sure to follow the manufacturer’s recommended maintenance schedule for your car to avoid problems like slipping, shuddering, or failure. If you are not sure when your Nissan’s CVT transmission is due for maintenance, consult your owner’s manual or contact a certified Nissan mechanic.
Transmission Fluid Flush
If you suspect that your Nissan’s CVT transmission fluid is dirty or contaminated, you may need to have it flushed. A transmission fluid flush involves removing all the old fluid and replacing it with fresh fluid.
Be sure to use only the recommended type of transmission fluid for your Nissan’s CVT transmission. Using the incorrect grade of this fluid can cause serious damage to the transmission and other components.
Repairs or Replacements
If your Nissan’s CVT transmission has already failed or is beyond repair, you may need to consider a transmission replacement or rebuild. While this can be an expensive option, it may be the best way to get your car back on the road and running smoothly.
If you need to replace your Nissan’s CVT transmission, be sure to choose a reputable mechanic or dealer who has experience working with Nissan transmissions.
Upgraded Transmission Cooler
If you suspect that the lack of a transmission cooler is causing problems with your Nissan’s CVT transmission, you may want to consider upgrading to an aftermarket transmission cooler. A transmission cooler can help keep the transmission fluid at a safe operating temperature, reducing the risk of overheating and other problems.
Be sure to choose a transmission cooler that is compatible with your Nissan’s CVT transmission and have it installed by a certified mechanic.
How To Prevent CVT Transmission Problems
- Regular Maintenance: One of the best ways to prevent Nissan CVT transmission problems is to schedule regular maintenance, including changing the transmission fluid and replacing the filter as recommended in your owner’s manual.
- Avoid Overheating: Overheating is a common cause of Nissan CVT transmission problems, so it’s important to avoid driving your vehicle in extreme temperatures or conditions. This includes avoiding heavy loads or towing, which can put extra strain on the transmission.
- Drive Carefully: How you drive your vehicle can also impact the health of your Nissan CVT transmission. Avoid sudden acceleration or hard braking, which can put extra stress on the transmission and other components.
- Upgrade to an Aftermarket Transmission Cooler: Installing an aftermarket transmission cooler can help prevent overheating and prolong the life of your Nissan CVT transmission. Be sure to choose a transmission cooler that is compatible with your vehicle and have it installed by a certified mechanic.
- Use the Right Transmission Fluid: Using the wrong type of transmission fluid can cause damage to your Nissan CVT transmission. Make sure to use the recommended type of fluid for your vehicle, and avoid using additives or other products that claim to improve performance.
- Pay Attention to Warning Signs: Finally, it’s important to pay attention to warning signs of Nissan CVT transmission problems, such as jerking, delayed shifting, or unusual noises. If you notice any of these symptoms, have your vehicle inspected by a certified mechanic as soon as possible to prevent further damage.
