    Anyone else hear this noise between 6-16 MPH, coasting or accelerating? It's the warning for blind people, right? Asking for a friend, anyone know how to disconnect the speaker?

    The warning noise for blind people is called VESS and can be temporarily disabled by pulling out fuse labeled "Module 4". There is a diagram inside owner manual. Because the fuse is shared with other components, you will also lose some other non-essential features like automatic emergency braking, blind-spot detection, etc. I suggest only pulling it when you want to record the noise and then putting it back.

    You can hear what mine sounds like with VESS disabled, in this post:

    I hear a rapid tapping or drumming noise that increases in frequency in the range you described.

    VESS sounds totally different. It's like the tune in this Kona EV video:

    Basically, the alignment of the shaft connecting the electric motor to the reduction gear was off, so needed to realign the shaft and re-grease with the correct grease (apparently, the improper grease was also used on this car).

    I'm waiting patiently for someone to post a YouTube video showing how to disable the VESS (and only the VESS) without leaving any warning lights on the dash. As far as I can tell, the VESS is a US federal compliance requirement on Kia as a manufacturer, not a requirement in most US states. (In other words, most people--maybe all--will still be able to get a passing vehicle inspection with VESS disabled.) The sound is annoying, particularly in echoey garages and parking structures.
