It doesn't sound like rushing water or pooled water, just a single drop sound.

    I have heard the same single-drop sound. It's almost like a recording of a water-drop sound effect: "bwop." It's from the rear right part of the car. It comes only sporadically, and it's too loud to be an actual fluid.

    Exactly! Any luck determining the cause?

    Not yet. My mechanic's never heard of this. Have you asked a dealer's mechanic?

    Not yet. I believe it started after I took it in for the 90k mile service. I have an appointment in a few weeks, so I will ask them.

    Did you ever find out? I'm having the exact same issue: A recorded-sounding electronic "bwop" sound (like an old Apple Mac "droplet" sound) that comes from the right rear on my 2007 Prius, which currently has 95K on it.

    It's sporadic, and I can't figure out it's relationship to braking or inclines.
