17’ 2.8l Canyon Whining noise

Have a 2017 slt canyon with 40k on it. Started to notice a whining noise the other day when I am accelerating. It is very loud when it is cold and as it warms up it gets better but doesn’t go away entirely. I don’t believe it goes away entirely when cruising but rpms are much lower so it’s way quieter. Wasn’t sure if maybe it was a pulley or pump. It almost sounds electronic and seems to be on the passenger side but hard to tell. Just wondering what everyone’s thoughts are? Thanks in advance.

Check fluids, my wife's Acadia had a whining noise. Ended up power steering fluid was low.
