chirpping sound

I don't remember anyone mentioning a squeaky gas pedal, might just need some WD40 sprayed on the moving parts. Your car is still under warranty why not take it to a Toyota dealer and see what they think?

 

You may be referring to the noise of the electric motor. Sorry, we can only guess here without hearing the noise over the internet.

 

The one you hear when you open the driver's door is the brake booster pump. When you shut the car off sometimes another pump runs to check the vapor recovery system. While driving you will hear a whine from the inverters.

These are the most common but there are others. Use the search function and search for noise or noises, you should find a lot of them.

 

There are noises also coming from the electric power steering. If radio is off, windows closed and I am not driving too fast (rolling noise low) I can hear a very faint, but distinct "inverter like" noise. It is intermittent and comes and goes depending on when and how much I accelerate or steer. It can also the noise of the AC electric compressor propagating in from the outside, which is not constant.
If you are still in doubt, I would go and "bother" your Toyota dealer

 

I hear a low "tung" when I let off the pedal quick. I think it is the stop inside the housing. Since it is spring loaded, I think you are hearing it bottom out.
Of course I can only hear this when the stereo is off.

 

I believe my Prius has the same problem. It has only 2500 miles. The sound is not loud but we can hear it very clear. You are right it is not the dashboard rattle noise. I have searched on PC and found other ppl have reported the weird noise, but I am pretty sure this one is different.

We noticed the chirp sound when car accelerates. So we tested it on local road and highway, the result is pretty consistent. I called the dealer and they have no knowledge of it .

I was able to record it on my camera but I don't know how to post it on here.

 

Alright, I have posted the video on youtube here it is.

 

Very odd... I have never heard that in my car.

 

Hmmm...I've never heard that sound either, though I rarely drive without my cd player going. I've got over 12,000 miles and have had my car since June of last year.

You find the sound while you're trying to accelerate? To me it sounded like you were already driving really fast.

 

I was doing about 40-45 MPH. I wanted to point the camera to the road but I was afraid of not catching the noise. I will try to get a better video.

 

I have another video.

 

Hyhi,

I have posted 2 videos, just wondering if it's the same noise on your Prius.

BTW, did you call your dealer and what did they say?

Thanks

 

My Prius is due for the 5000 service, I'm going to ask the dealer to take a look at it.
Will keep posted.

 

I am having this problem - any resolution?

 

Thought I would let you all know my solution:

ust got my car back from Toyota. It seems they have fixed it! They called in a specialist (after their technicians couldn't diagnose it) and he said that it was a rattle of the "heater hoses and clamps" caused by the engine/antifreeze temperature combined with the RPM's of the motor. They rerouted the hoses and installed the clamps in different locations. Currently, my car is not making the noise. They said if it comes back let them know and they will try again.

So, if your car is making this noise - its not normal but it could be a common problem, seeing as to it was an engineering/design issue. If anyone is having this problem and takes their car in and the technician can't figure out what it is my service manager said they can reference this claim number: 111570301, to see what my service dept. did to fix the problem.

Good Luck!

 

Thank you soooooo much. I will contact my dealership next week to see if they are willing to fix for me.
