The noise in your video is with the engine OFF ? Its hard to tell bc of all the other background noise. IF so... its probably your electric water pump going bad. They should not make any noises like that.

I would have a dealer check for any waterpump failure codes. Normally you get a code thrown shortly before the pump dies. But you would never know bc you do not get any warning lights, until you are left stranded on the side of the road.
