Hello - hoping someone can help. Purchased a used 2021 Elantra. Attached video with audio of a chirping sound. It does this randomly, and I even heard it with the car off. I can’t figure out if this is coming from the car itself or if there’s some kind of device in here making the sound. Anyone heard this or might know what it is? Sounds like coming from rear of the car.

Thanks!
