 I love my Infiniti.  What I do not love is the CVT transmission.  I bought the car (LOADED by the way) in April 2015.  We have certainly had our issues along the way, but BY FAR, the biggest issue is the CVT transmission.  It started after we had a transfer case FAILURE, but I won't go into the story.  My car started to have a vibration around 30/40 MPH when trying to stay at a constant speed.  If you do a lot of local driving like I do, you are in this constant speed mode a lot.  The dealership says they cannot 'replicate' the problem.  It gets worse, and since I drive a lot, I am in the dealer about once a month for an oil change.  EVERY MONTH I complain.  Every month, they cannot replicate it.  The last time in, I was set to leave it for life.  They got the service manager and he drove it with me in the car.  He told me that he would contact their area rep and he would come sometime later in the month (August) and we would all go out for a drive, but that his opinion is the 'definitive' opinion.  In other words, he would come out and tell me they cannot replicate it.  So August has come and gone.  My husband called the service manager three times and has not had the courtesy of a return call.  So we have been doing research.  This CVT engine has been a real problem for Nissan.  There is a class action suit for the earlier version CVT .  I think they may have changed some part of the CVT, but I am now deathly afraid to put my children in this car.  Did I mention I have 65K miles...yes, I drive a lot and we travel.  There is a rumor the new 2018 will have a different transmission.  I have been reading online how Nissan North America is not at all helpful.  As I said, love the car, but I cannot safely live with this transmission.  If I hear 'replicate' one more time, I will scream.  They use it for everything.  I had a noise in the fan area for ac/heat.  Can't replicate.  MY HUSBAND took it in THE NEXT WEEK, and all of a sudden, there was a new something needed.  My service advisor told me that Nissan doesn't care about customers, they just want to make a profit.  How about that?
