Prius Squeaking Dash

Squeaks can be difficult to locate and then also difficult to fix. But a common one in the dash area is the plastic trim in the tiny A-pillar window. When you hear the squeak try pressing down on it (a passenger will have to do the passenger side) and see if the noise changes. Other than that... press on all different parts of the dash WHILE you hear the squeak in motion and check the contents of the glove box. Try sitting in the passenger seat yourself and listening, a different perspective might help locate it better. Good luck and be sure to update when you find and fix it!

my body shop gave me a brand new aftermarket side mirror after I got side swiped and I had a high pitched noise above 40mph, he then gave me a used OEM mirror and the noise went away, visually I couldn't see any difference b/t the mirror but i'm pretty sure toyota tests in a wind tunnel and smaller companies do not.

my problem was easy to diagnose, but the body shop guy says most noise problems are difficult to pinpoint so best of luck to you lad

 

The whistle noise at high speed probably comes from one or two open holes in the mirror housing. The holes on the underside of the Prius mirror housing are covered with tape and if the tap falls off then comes the whistle.

 

Here is a great way to fix this kind of noise:

I had the same problem in my 2008 Prius and agree that the noise is coming from the area adjacent to the little window in the A pillar. I believe the noise is exacerbated by the attachment of the vent duct from underneath and I've noticed the problem is much worse when the weather is cold outside and the noise goes away when it get warm. I fixed it by wedging some black foam between the glass and the plastic panel that has the duct connected to it. The bottom of the glass has a black band around it and hides the foam well.

 

My wife's 2007 has this sqeaky sound in the dash also. Except for her it gets worse when the tempature goes up - 80s-100s. Goes away in the winter...Haven't taken it to the dealer yet as I don't know if this is covered by the extended warranty.

Try tightening up the screws in the glovebox.
