Whining noise coming at startup

Hey all, recently, my 2017 SR with 84k miles has been making a high pitched whine when it first starts up. For a while, it was just at startup, but today I noticed it a little (although quieter) while driving. Any idea what it may be? I’ve read some things it might be the serpentine belt, but I checked my belt and no visible cracks or anything.

I would check the serpentine belt. Visually might be good but if it’s loose it might cause the noise issue or a possible pulley starting to go bad . I would spray some lubricant around the moving components avoid any on the belt .

 

And or the power steering fluid.
