    Hello everyone, I am having a rattle noise coming near the dashboard area.
    It is a 2021 prius prime XLE model and even though it is only 33K, it is out of warranty.
    The sound is similar to the below youtube video. It is generally a squeaky sound.
    I have tried many things, tighting hte wiper nuts on both, pushing the heat duct under the dashboard area, Tightening many of the bolts, and test the steering wheel but with no luck getting rid of the noise. It tends to be louder when it is on uneven road, and higher speed. Got a video below that will depict the sound I am talking bout.

    If anyone has any idea, I would appreciate your comment/help.
    Thank you in advance.

    I think it could be this.

    Thank you for the video. I believe that the squeaking sound is more of a metal to metal sound, and it sounds like it is ocming from the left side oft he car.

    Most of the bad squeaking Gen 4's were from 2016 til 2018. Not heard of this much in the 2021 models. Good luck and report back if you locate where it's coming from.
