2021 Mazda CX-5 High Pitch Noise

[Ryland_01]

My Cx-5 makes a high pitch squeak when coasting at different speeds very inconsistent but also makes that same squeak when turning off the car even when it’s just the battery on and I turn the car off. It sounds like it’s not coming from under the hood. Anyone have any idea what this could be?

The High pressure fuel pump makes a high frequency noise which lasts several seconds after I shut the engine off.

Okay this is the sound. Almost sounds like metal on metal.
