    There is a strange tweety-type noise coming from the passenger side dash. It's seemed to not be as loud when at increased speed. It's there when in Park, as well. I called Service and they've not heard of it and said to bring it in. Has anyone had this?

    I've noticed a similar noise coming from the passenger-side, behind the dash (but actually from the engine-side of the firewall) in my 2009 Gen II (163,000 miles). The noise is quite noticeable when the engine is cold and is absent after everything warms up. It sounds a bit like a dry bearing. The car is almost due for a 5k service so perhaps I'll have them take a listen when I take it in.

    Welcome to PriusChat!!

    Was this for the 2017 Gen4 in your profile, or are you referring to another Gen2 in your fleet?

    See if it changes with fan speeds. If so, check for debris in the fan assembly.
