Nissan

I bought my Nissan Juke 4 months ago. Since last week that the exterior temperature is showing wrong information. I contacted the dealership (myself because my wife called before and they said that they had few complains before with similar situations and would be loosing their time to go there with the car because they did not find any problem) where i bought the car and first they told me that they could not do anything, i called to my home country and asked my father to contact Nissan there as i also have a Juke. The said that the service in my dealership need to fix the issue as they already had similar issues and they changes the sensor and problem was solved. I have several videos showing the real temperature outside and what the car is showing (Example: Outside 18 car is showing 32). I have more examples in video when the car is standing all night and real temperature outside is 12 car is showing 25 ( no sun). The person who took care of my case told me that the sensor is good and that they contacted the warranty manager who denied to change the sensor for me. If the car and the sensor were OK until last week it is obvious that there is an issue with the sensor or anything else. Did not liked the way my process was conducted and i am very dissatisfied with service provided that was none.
