Another historical problem is the transmission belt slipping. The belt, which connects the pulleys and adjusts the gear ratio, may slip due to wear and tear, causing the vehicle to jerk or shudder while accelerating. This problem was common in Nissan Sentra, Nissan Altima, and Nissan Rogue models manufactured between 2008 and 2013.

Additionally, there were also issues with the CVT torque converter. A torque converter is used to transmit power from the engine to the transmission. A faulty torque converter can cause poor acceleration, shuddering, and even total transmission failure. The 2007-2012 Nissan Altima and the 2013-2014 Nissan Pathfinder were among the models affected by torque converter problems.

Lastly, another historical issue includes a delayed response when accelerating. The car might take a moment to ‘catch up’ after pressing the gas pedal. This issue was mainly reported by Nissan Murano and Nissan Rogue owners.

Known Recalls or Service Bulletins

Nissan has issued multiple recalls and service bulletins over the years regarding its CVT transmission. One of the major recalls was in 2009, when Nissan recalled over 200,000 vehicles, including the Altima and Sentra, due to an issue that could lead to an increased risk of a crash.

In 2013, Nissan issued a recall for over 300,000 vehicles, including the Nissan Altima, Pathfinder, and Sentra, due to a software problem that could cause the vehicle to stall. This recall included a free CVT software update which aimed to resolve the problem.

Moreover, in 2014, Nissan extended the warranty on their CVTs for certain models manufactured between 2003 and 2010. This extended the powertrain warranty from 5 years/60,000 miles to 10 years/120,000 miles, indicating Nissan’s acknowledgment of the CVT transmission’s problems. This included 19 models like the Maxima, Murano, Sentra, and Versa.

Signs of a Failing CVT

It is essential to recognize the early signs of a failing CVT to prevent more significant problems and potentially expensive repairs. Below are some common symptoms of a failing CVT:

Unusual Noises

One of the earliest signs of a failing CVT is unusual noises coming from the transmission. A well-functioning CVT will operate quietly and smoothly. However, if you start to hear high-pitched whining, rumbling, or rattling noises, it is a sign that there might be a problem with your CVT. This could be due to worn-out bearings or a failing belt or chain. It’s essential to address these noises as soon as possible to avoid more severe problems.

Delayed or Erratic Acceleration

A CVT should provide smooth and continuous acceleration. If you notice a delay when you press the gas pedal or if the vehicle’s acceleration is erratic and the RPMs are jumping around without a corresponding increase in speed, it could be a sign that the CVT is failing. This could be due to a variety of reasons, including a worn-out belt, a problem with the valve body, or a failing torque converter.

Overheating

CVTs tend to generate more heat than traditional automatic transmissions. However, if the CVT is overheating, it can be a sign of a problem. Overheating can cause the transmission fluid to break down, leading to increased wear and tear on the transmission components. If the temperature gauge on your dashboard is reading higher than usual or if you notice a burning smell, it’s crucial to address the issue immediately.

Slipping Between Gears

Although a CVT does not have traditional gears, the term ‘slipping between gears’ is used to describe a situation where the transmission cannot maintain a constant speed or ratio. This can cause the vehicle to feel like it’s jerking or shuddering during acceleration. It could be due to a worn-out belt or chain, a problem with the valve body, or a failing torque converter.
