Hi, welcome to Just Answer. My name is***** would definitely recommend getting the car inspected. Diagnosing a whining noise over the internet can be difficult. A whining noise associated with cold weather usually comes from the power steering. I would suggest that you get the car to the dealer to have the fluid level checked in the power steering and have all of the other fluids checked as well. They should also check the belts and pulleys for any bearing nosies. The dealer may need to keep the car overnight in order to duplicate the noise.
Let me know if you have any questions.
