I don't know about the waterfall noise. I've never heard a description like that. The issue with the brakes is a problem with the ABS. This should be checked by a qualified tech.

We have the same noise and still finding what it is............. Any one else?????

Possibly low coolant level and what you're hearing is the coolant, and air bubbles, being pushed through the heater core when the engine is running. The heater core is under the dash on the passenger side and this is a common complaint when the coolant is low.

The buzzing brakes is most likely due to a problem with a wheel speed sensor for the ABS brake system. The vehicle must be checked out with an ABS capable scan tool to acurately diagnose it.

Sometimes a 'waterfall' noise is caused by a seized fan clutch.... which causes the cooling fan to push far too much air than is required.
