HELP - High pitched noise when driving

You know that DVD that came with your instruction manual? Watch it.

 

Hey my neighbor was asking about that cd he has the case for one but don't have the cd. Do you know where he can get it.

 

i have the high pitch sound also.

it happens when the brake pedal is pressed.

the car can be moving or standing still.


something is wrong because i didn't have this noise when i first picked up the car.

i started noticing it after the tech took the dash apart.

anther tech listened to it and seemed to be familiar with it and will fix it next week when they fix my ipod connection.

 

I picked up my Gen III a few days ago and it had a horrible sound immediately. It only stopped when I was at full stop. I took it back and they looked at it and the next day they said there had been a pebble in the suspension (car people, does that make sense?) and all was good now.

So I drove it home yesterday and the horrible sound is gone, replaced by a high-pitched annoying sound that happens during acceleration. I suppose I could drown it out with the radio but I just paid a lot of money of a brand new 2010 Prius. Do all 2010s make this sound? Or should I take it back?!

 

Go back to your dealer. There is NO annoying noises what so ever in Priuses. What you describe is not normal and should be looked after by a competent tech.

 

I have heard the sound you describe and I don't think that anyone responding so far has heard it. It is a low volume but very high frequency "thin hiss" coming from the engine compartment. I hear it occasionally, when the car is very silent (the air conditioner is on, radio off). I've learned to ignore it.

 

I have a Gen III Prius V /w ATP that I just picked up today. I hear this faint high pitched noise coming from the direction of the dash as well. It tends to happen when I accelerate and goes quiet at times, changing pitch occasionally as well. Is this normal? I wonder if the original poster ever got this checked out by the dealer.. Being the the noise is so high pitched, I'm assuming some might not hear it as well as others.. perhaps younger people would notice it more. I'm going to mention it the dealer the next time I'm down there to see what they can do.
