How reliable is the CVT transmission of 2016 altima?

What is your question?

How reliable is the cvt transmission of altima 2016 compare to altima 2013-2014-2015? I'm asking that because those models are having a lot of problems with their transmissions. I own a 2.5cc S 2016 with 50k miles and I'm super scare bc the most of the people experience troubles with theirs around 50-60k miles. So i don't know is it is a good idea to sell the car before it happens. I ask to the dealer and they say that they do not put new transmissions when they have to change them, they put refurbished ones.
