If you've never had your brake pads replaced then the brake pads could be worn down and could be causing the brakes to squeal while driving.
Brake pads have a wear indicator on them that touches the rotor and is supposed to make noise while driving so the squeaking brakes could be caused by that.
If the brakes only squeak or squeal when you press down on the brake pedal to stop then the pads could be bad or you could have a warped rotor.
However the most common cause of brake squealing and squeaking is inferior brake pads.
I would take the car to a shop and have them inspect the brakes just to be safe.
