You did well to research this. Nearly all Nissan vehicles with automatic have or will have CVT transmissions. These units cannot be repaired or rebuilt by Nissan or anyone else. They are changed out in case of problems, and once out of warranty you will foot the entire bill.
As a result, I am reluctant to recommend ANY car with a CVT for the time being.
There are lots of other good vehicles on the market. Please note that the economy model of the new 2014 Corolla also has a CVT.
