My mom has a 2012 GMC Acadia with about 104k miles. It’s oil and filter is going to be changed tomorrow as scheduled but I started the battery to check the odometer because I was curious and it started making a weird noise, and I started recording to take note of it. It magically stopped about 7ish seconds after I started recording. I don’t even know how to describe it. I posted a video so you can listen

Was it just the one time?
Go on and tell us everything you know. Be as specific as you can.
It happened once today, but it hasn’t done it since. I don’t even know how to explain it. It sounds fluid-like. I think it could be some sort of pump? Hopefully they find it when it goes in today, but I want advice on what it could be so we don’t get scammed on something that wouldn’t cause it.
