i have similar rusting yellow spots on rotor only 4K ,2021 elantra model
taking it to service to see whats going on
Some parts of the rotor don’t come in contact w/the pads, and there it’s normal for rust spots. If there’s rust spots on the rotor in the pad area, and you drive the car daily, your plan to have a shop check it out is a good one.

Rotors are bare cast iron. It must be bare where the brakes touch to work properly. Iron rusts. These are facts of life.
What you see is normal.
