High-pitched beeping sound

[HowdyDoody]

Recently I discovered a high pitched beep-type sound when driving between 55 and 65mph. It's not loud, in fact with the windows down or the radio up, I can't really hear it. But it's impossible to tell where its coming from, and I only hear it when I am sitting in a normal driver position. If I lean to the side or front and back more than a foot away, it subsides. It's bizarre. Anyone else experienced this issue? Could it be the tires?

I have heard something similar. It sounds like a high-frequency, low-tone tone intermittent beep about every twenty seconds or so with a duration of .5 to 1 second. It almost sounds like a quick dog whimper--and yes I made sure no dog was living in my frunk. I can only hear it with the windows closed and the radio off. Nothing is associated with it, so I pretty much ignore it. My Mach E has enough other issues.

To clarify it only happens when driving 60mph +-5mph and is a fast paced beep, like 120 bpm

I think you need to check front motor drive and its oil.
