Please explain "doesn't have a clue". What exactly did they say?
No lights on the dash are normal and fine. They may be irrelevant to what you're asking about, but they're telling you that There Are Problems, noticeable or not, and a forest of codes from irrelevant things can make diagnosing the problem you do care about overly complicated and expensive.
Circling back to thank all who provided advice. It turned out be a front left speed sensor and my eMileage is slowly ticking back up to normal. Thanks!Probably not but depends on when you hear it. Brake or wheel bearing sounds would be directly related to vehicle speed. So constant or periodic sound getting louder, changing tone, or getting faster with vehicle speed. Something not periodic and squeaky is probably a ball joint, bushing, or shock. You would then only expect it to make noise when going over bumps or rough pavement. It might be possible to replicate by bouncing the corner of the car when stationary.
