It can be heard at idle and parking lot speeds, but nothing insane. Certainly if the radio is on even quietly or if you’re cruising down the road it definitely can’t be heard at all."
Even if it is "normal" meaning it functions correctly I'm not ok with that level of noise. It's super annoying.
Here's a other video from inside

It’s pretty loud. Mine chirps at idle and low speeds, but nothing crazy like that. It’s one of the originals pumps. Try to warranty the pump? Talk to them. My o-ring was seeping a bit of oil residue and I hit them up asking to purchase a new one and they sent me 2 for free.
