Odd Sound

getting ready to part?

Describe the noise please.

 

Is it kind of a consistent ratcheting sound, like clicking? And heidm asked but you didn't answer. Can you clarify what you meant when you said, when you were getting ready to part? Park?

 

It might be the brake system. It adjusts the pressure in it's storage tank and there's a little compressor that makes that kind of sound. Typically, you have your foot on the brake when you park. Try shifting to N and taking your foot off the brake (assuming you're level and safe doing this) and then press the P button and see if the sound goes away.

I don't think it's anything to worry about.

 

My Prius has a rattle near the little window on the driver's side.

 

I noticed that mine does that too. It's normal. Though I did notice that when I first got the car, after I shut it down, I could hear this whine sound, that runs for about 10 seconds or so, then shuts off. I learned thats the transfer pump. Anyways, Latley I noticed that it sounds kinda sandy now. Like if there was pieces of sand or something. I have a feeling that is not normal. maybe the bearings are going out on it.

we will see.

It's a 05 with about 7,800 miles on it.

 

I have about 7200 miles on mine right now and it is doing the same thing. I have a tread out there about my experience so far with trying to get a dealer to acknowledge it. Let me try to find that and link it here.

Well, it appears that the entire topic about my loud hot coolant transfer pump was lost during the recent Priuschat loss. That really sucks. :angry:

 

The bees, the bees! And the talking spiders! Aaaah, make them stop!

 

What ever became of your noise? Did you get a new pump or are they still trying to find the source of the noise? To bad the thread got lost, .

I have the same noise. Bumping to see if anyone else has a metallic rattle/buzz coming from the driver's side B-pillar area. I've had mine into the dealer 2x and haven't gotten it corrected yet.

I hear it in my 2006 from time to time, and only when braking. It does sound like a tiny compressor or well-insulated vibratory pump.

Not the braking system..its a buzz in the cabin where the driver's seatbelt connects to the B-pillar.

 

I had this problem. The dealer didn't fasten the nut that is holding a plastic flap that is located in front of the rear tires. Maybe you can try to see if any plastic flaps are loose?

 

Bump. This noise is driving me nuts.

I took my '07 in to the dealer today for the same noise and the mechanic told me it was the ABS pump and sure enough, even if the car is parked, pressing the brake pedal multiple times will produce this noise. Mine seemed louder than the other two cars he tested but they all made that noise. Kind of annoying but it's not something they will address since they all seem to do it.
