Sometimes voicing your concern in a way that gets Nissan's attention does the trick. Someone once complained in a YouTube video, it went viral, owner got a response 
Just make sure its a reputable dealer that's willing to investigate the issue, some brush it off unless there's a TSB to go with.I noticed the same issue... I can't stand to be in the car above 62 degrees... But I did notice that after the car has been running a while, and if it is cold outside, I'll juice the temperature to 65-68. Thankfully, the engine heats up quickly!
I also noticed that in the summer, the air conditioning doesn't get "ice cold." I keep the air set on "auto" at 60 during the warm months.
My husband noticed the same issues in his Kicks, too.
Next time I'm in for service, I'll mention it to my garage. Can't hurt!
have the same problem with my kicks sv. at 61degrees it is cold and 62 and up it is 90 degrees. after the first week i took it back to the dealership (Michael Jordan Nissan). the first visit they replaced a sensor, the second visit they replace a sensor board. still didn't work. after they contacted Nissan they told me to call Nissan direct because they couldn't figure it out. i had to go thru arbitration because i didn't want a car that isn't 100%. Nissan said they would have to send there own tech for an inspection in order to determine if they would buy back the car. the next appointment they had available was in 2 months. thankfully MJnissan gave me a rental. 2 months goes by, their tech comes with me there and sees the same issues i was complaining about and tries to tell me this is normal and reports to Nissan that it is operating as it is designed. they denied my arbitration request to get another vehicle. they offered me a settlement of $1500 dollars for my inconvenience and for the repairs and if i accepted in turn i would have to agree to not sue them. and i am stuck with a car that you cant control the temperature. has this happened with anyone else? and no i did not take the settlement.
