Could also be power steering pump.
Whining noise at all rpms - suspect serpentine belt
Hey There,
This is my first post on here, I have a 2015 subaru XV with 117k and haven't had too much maintenance to deal with up until this point. However, I am having this whining noise at all rpms, and it is especially noticeable during the high idle period after starting. The AC compressor switching on does not change the sound much. During research people have said that it could be the idler pulley or the water pump bearings. However, when I sent it to a friend thats super familiar with cars, it was not the sound he was expecting. I've never replaced the belt, so going to start with that for sure and investigate all the pulleys. I've attached a video of the noise right after starting. Any advice is appreciated, thank you!

I'd be looking at the alternator but you really need to get a stethoscope (link below) and listen each component be it idler alternator or power steering pump. I'd replace an idler but I think I'd let the others go awhile.

I had the EXACT same noise. It was a cheap simple fix. IDLER PULLEY $67 bucks. BAM! Piece of Cake.Hey There,
