Common Problems with Nissan CVT
Historical Issues with Nissan CVT
Nissan has faced various issues with its CVT transmission over the years. One of the most common issues includes the transmission overheating, leading to the failure of other parts. This is primarily because the CVT generates more heat than traditional automatic transmissions. The transmission fluid would overheat, leading to the CVT not functioning correctly. The 2003-2010 Nissan Murano was particularly affected by this issue.
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.

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.
Warning Lights on Dashboard
Modern vehicles have a sophisticated computer system that monitors various components’ performance, including the transmission. If the computer detects a problem with the CVT, it will illuminate a warning light on the dashboard. This could be the ‘Check Engine’ light or a specific transmission warning light.
