Nissan has a 10 year warranty on all CVT's...they are not that bad, or pricey, but if something were to go wrong you do have to replace the whole CVT unit, cannot open it.
The one in the Rogue isnt noisy but if u drive like a grandma then you can feel a slight vibration due to the torque convertor locking/unlocking
Also the 08/09(think the 10MY too) had the paddle shifter/manual shifting option which can be pretty fun. Unfortunately Nissan removed it from the newer 2011/12's.
As well as the Rogue is not that great on power 170hp/175lbtq, even though the Rogue paired with the CVT makes for excellent low end torque, the Mazda cx-5 turbo motor definitely has more grunt and power, but is thirsty, and requires premium fuel.
The new Kia Sorento's aren't bad either
As said above go testdrive all of them yourself.
