CVT Transmission is awful!!!
 I bought a used Rogue a little over a year ago.  It had 45,000 miles on it.   The transmission started making a weird whining noise this summer.  I googled the issues and was shocked to see the list of issues with the CVT transmission.  I ended up bringing it into to Nissan and was told that sometimes with the heat the CVT transmissions will whine but to have the fluid levels checked often.  It did stop whining when it got colder and I have the fluid levels checked when I get my oil changed.  Well today out of no where my transmission went.  I wish I had researched a little more before buying this vehicle.  A quick search will show pages of complaints on these transmission.  It's a clear problem.  Don't buy!!
