HI!
I know that we have had some CVT transmissions with whine noises and had to replace the transmission , if you think it is to loud and the dealer will not fix it , you can go to another dealer or call Nissan at 1-800-Nissan-1 they will make sure your car is fixed and make you happy, Thank You, Let me know if you have any more questions, ROY!
I have not seen this problem cause a problem just a noise, I think you will be ok to drive your rogue Thank You, Let me know if you have any more questions, ROY!
