This could be an issue with the CVT control cable or the control module.
The tricky part is that the vehicle is not showing any error codes (warning lights).
Nissan did have some recall for these CVT transmissions.
Do you know if that recall was performed?
If you are not sure just call your local dealer and provide them with the VIN and they can let you know.
