Nissan has had a lot of problems with their CVTs for a long time now. They have a high failure rate in almost all the cars they use it in. Once the new CVT's warranty ends, I suggest getting another car. It is unfortunate that Nissan continues to use them because their cars hold up otherwise.
If you are looking to trade for a similar car, the Honda HR-V, Kia Niro, and Hyundai Kona are great choices. If you want something bigger, the Honda CR-V, Toyota RAV4, and Mazda CX-5 are the best.
