Transmission failures in the Teana mainly occur in the 2011 model. Regarding the symptoms of transmission failure: 1. Inability to accelerate: After prolonged driving, the vehicle's speed remains at 120km/h, and the car exhibits an inability to accelerate. The engine RPM continuously rises, but there is no significant increase in power. Even after restarting the car, the transmission issue persists. 2. Jerking phenomenon: When driving at normal speeds above 30km/h, the car experiences jerking. Pressing the accelerator pedal still fails to improve acceleration. 3. Engine burning smell: During normal operation, the dashboard displays a yellow warning light indicating engine trouble. Continued driving may result in a burning smell from the engine, severely impacting normal vehicle operation.

I remember working in the auto repair industry for many years, and the CVT issues with the Altima mostly appeared in models from 2008 to 2012. The main reason was some design flaws in the transmission during those years—the internal chains weren't very wear-resistant, and combined with poor oil temperature control, it was prone to overheating during long highway drives or in stop-and-go traffic, leading to sluggish shifting, vibrations, or strange noises. Many owners started experiencing problems after around 50,000 kilometers, and repairs were costly, often requiring either an oil change or a full transmission replacement. Nissan made minor improvements starting with the 2013 model, and by 2015, the issues were mostly resolved. For those driving these models, I recommend regular fluid checks to prevent small problems from becoming big ones. Safety-wise, if you notice any issues, address them immediately—don’t risk an accident on the road.

As an owner of a Teana, I've driven the 2010 model, and the transmission was a major issue. Models from 2007-2013 commonly had faults, with the CVT chain prone to wear, causing jerking or strange noises when accelerating. A friend of mine experienced overheating and breakdown in the 2012 model, costing nearly ten thousand in repairs. Nissan redesigned the models after 2014, and there have been far fewer complaints. For daily driving, it's important to accelerate gently and maintain regular oil changes. This issue affects the driving experience, so if you're buying a used car, avoid the 2009-2011 models.

Those familiar with cars know that the transmission issues with the Teana were concentrated between 2008 and 2012. The CVTs from those years weren't durable, with frequent oil pump or chain defects, manifesting as rough shifting or sudden deceleration. After Nissan's optimizations in 2013, reliability improved in the 2014 models and beyond. Maintenance-wise, early oil changes can mitigate risks, but older models still require caution. Market feedback data shows a peak around 2010, so it's best to avoid buying used cars from that period.
