Mar 1, 2015
It's been cold, but I've been driving. When I park and power down, I'm hearing a high-pitch sound...like a fàn...it lasts about 10 seconds.

Ford F-150 (2004-2008) :: Metallic Clacking Sound At High Speed / Low Pitch Whirring At Low Speed?
I have a 2004 F-150 SCrew Lariat 4X4 with 80K miles. Over the past month or so, every once in awhile there would be a loud metallic "clacking" sound (kind of like sticking a peice of aluminum in a bike's spokes) that would start at higher speeds and would turn into a low pitched whirring gear sound as I slowed down and eventually there would be a thud followed by a sensation of running over a small bump and the noise would be gone. Kind of confusing I know, but that is the best way to describe it. My gut feeling is a wheel bearing or transmission problem....

I've noticed, maybe a handful of times in the 5k miles I've owned the car, that the engine will rattle excessively for maybe 30 seconds or so on a drive. This only happens during high load/low speeds and I think after the engine has been off for at least about 10-15 minutes. It doesn't happen on start up, only after the car is warm, but hasn't been using the engine for a bit. I'm thinking this is fuel enrichment (really rough running) because the cat has cooled.

I have a 2013 Prius c #2. At 62 mph and faster there is a high pitch sound that gets louder the faster it goes. I have asked two other Prius c owner's and they don't hear it. You will need to roll up the windows and turn the radio off to hear this.

My 2004 V8 Toureg has around 7K miles on it. The brakes are squeaking at a very high pitch. The same squeaky sound a bus makes when it stops. My dealership told me it is due to me not hitting my brakes hard enough. I have hit my brakes hard many times as of late and the squeaking continues loudly as folks will turn their heads. The dealership told me it is due to brake dust accumulation which if I wash the car they still squeak. Dealership also told me the VW regional field rep has told them that to rough up the brake pads which is a temporary fix. Dealership also stated if the brakes were replaced the brakes would start squeaking in a matter of a few months because this is how German cars behave. Not sure where to take this matter.
My other problems as of late are a bad power steering pump(replaced), bad suspension controller arms(new parts are ordered-kept hearing a popping sound when turning the tires and braking and grinding noise from the suspension), a bad keyless access module(replaced), steering column not centered(re-centered), wind noise from the rack ontop (basically to fix and probably only temporarily, unlocked them and then moved them forward a bit and then back to their original location- may have been loose as no more wind reverberation inside the car now), and rubbing from my driver side wiper. The brakes are the real thorn in my side at the moment due to other drivers hearing the noise while driving as they turn their heads. Very embarrassing especially coming from a new car!!
Prius Plug-in 2012-15 :: High Frequency Pitch Sound
When I test drive the PIP, I kept hearing a high frequency pitch noise whenever the car was accelerating. It almost sounds like when you lightly touch the trigger on a cordless drill. Sales guy and my wife couldn't hear it, but I do have extremely sensitive hearing.
A quick search didn't reveal anything, so I am wondering if this is a problem, or maybe part of the pedestrian warning system (although it happens at higher speeds as well).
Prius (2004-09) :: High Pitch Whine At 50 Mph
I've got a 2006 Prius - yesterday afternoon my wife and I noticed a high pitched whine coming from the front (maybe right hand side) of the car - we don't hear it until we reach about 50mph. It gets louder as we increase speed and then trails off when you step off the accelerator and can't hear it all below 48-45mph.
We bought the car new and are familiar with the various noises the car makes, but this one is new - never heard it before yesterday.

I have a 2003 Toyota Prius, that you have to push sooo hard to make it stop, the ABS and brake light are on and there is some aweful chime that is solid and doesn't go away (very high pitch), I just got the car, and got it like this. I think its signs of a BRAKE BOOSTER, but I have been unable to loacted that, I found the Master Cylinder, but looks like you have to remove the Hybrid engine to do... Is there a procedure for this...

My 2007 Prius Touring creates high pitch Squeak/Whistle sound while accelerating and braking, But if I put the car on neutral then the sound completely goes away. I have all the holes covered on the both side mirrors and this still occurs. The sound is constant for as long as I accelerate and Brake and the intensity varies with how hard I accelerate or brake, It also does that during regen braking when I leave the accelerator.

View 2 RepliesPrius (2004-09) :: 2005 - High Pitch Noise That Won't Stop And Locks Up?
I tried to start my 2005 Prius this morning and a high pitched noise started (the same noise that happens when you hit the power button without having your foot on the brake). The emergency light was locked on as well as a message on the display screen about setting the emergency brake. This has happened one other time an after about two minutes the noise stopped, and I was able to start the car. This time the noise and lock remained for about 20 minutes until we disconnected the battery in the back. We re-attached the battery after we removed the ignition key and after a few moments all the power seemed to be gone. The fob doesn't work at all and the electronic lights and dash flickered and faded out. Our gut instinct is that the battery needs to be replaced. Was it the 12V battery?
View 5 RepliesPrius (2004-09) :: No Whirring Sound After Shutdown
I have a concern about not hearing the whirring sound after shutdown anymore. I know that the sound comes from a small electric-pump that pumps 3 liters of coolant into a thermal container (to keep it hot) everytime I turn the hybrid system power OFF. When the power is turned back ON, the coolant is pumped back into the engine.
I've noticed that after I got an oil change and tire rotation at Pep Boys the sound is no longer there after shutdown or power up. Then after a couple of days I took the car to the dealer to fix the tire rotation (because Pep Boys didn't do a good job at rotating the tires, there was a woo woo woo sound while driving) and the dealer also did a multi-point check, but they didn't say anything was wrong with the car.
Prius (2004-09) :: 2006 - Motor Whirring Sound After Turning Off?
We are only one week in to owning our 2006 Prius! Question is why does it sound like a motor whirring sound after turning it off? It only lasts 20 to 30 seconds, just wondering if this is a normal sound?
View 4 RepliesPrius (2004-09) :: 2005 - Whirring Sound When Take Foot Off The Gas Pedal
I have a "05" Prius problem that I'm stumped on. I have 165k miles. I am the original owner and have maintained this car really well and it really runs incredible. I just started to hear a strange new whirring/winding sound coming from the front when driving. When accelerating it goes quiet. When I let off on the gas it starts whirring. Between 40-45 MPH if I let off on the gas it will whir but then when I drop below 40MPH it does it intermittently. It almost sounds like it is attempting to slow the car down . I've looked over the forum and other sites and hear about other sounds like this (ex: A/C motor), but nothing that matches my symptoms. I can say this, it in no way affects the performance of the car, just very annoying. If it is serious I would like to jump on it right away and try for 200K .

My "05" Prius has 164K, I'm the original owner and I have had great success with this car. I know some owners talk about the loud whining humming sound from the A/C unit which I am aware of but this newest sound is different and after 4 hours with a Toyota tech all they can come up with is an A/C compressor going bad. I only hear this sound after I reach 40MPH+ and then decelerate. It then winds down with the speed of the car sometime intermittently. If I accelerate it goes quiet.
I've also tried speeding up to 40MPH and then move into neutral. It will stop the noise. I'm adding a video and I realize there is standard road noise but if you watch my energy monitor you will hear the noise whirring winding when the green arrows point back to the electric motor. Pay close attention to the viseo frames at 13 seconds, 22 seconds and again at 29 seconds. Turn up the volume. Of course inside the cab it is much more pronounced. I'm finding it hard to believe this is an A/C compressor. Sounds more like an electric motor whining/whirring. I'm concerned about driving my car for safety reasons.
Prius (2010-12) :: High Pitched Sound - RPMs Go From 1200 Up To 3400 In 10 Seconds
I was driving today and had just gotten off the highway. I was going at no more than 10MPH when I heard some high pitched sound. At first I couldn't figure out what it was and thought maybe it was some outside noise. It quickly got louder over the span of the next few seconds and then I realized it was the engine. I had the pedal barely down so was definitely in electric mode.
I quickly glanced at my Scan Gauge and actually saw the RPMs go from 1200's up to 3400 in no more than 10 seconds. I have never had the car rev this high, probably just 2400s when I'm on the highway going 70's. By this time I was getting very perplexed and worried, and had my foot completely off the gas pedal. I immediately pulled to the side of the road and parked (hit the P button). The car seemed to go into park mode fine and then over the next few seconds the RPMs went back down to 992, and I made it back to the house no problem.
Prius (2004-09) :: 2008 - Constant Whirring Sound When Engine Is Running
My 2008 Prius has started making a noticeable soft whirring sound whenever the engine is running. You can hear it both inside and outside of the car. The sound lasts exactly 30 seconds, then pauses for 4 seconds, than repeats . When the car is turned off, the sound can be heard for about another 10 minutes before it shuts off entirely.

I have a 2009 Prius with about 56K miles on it that I absolutely love. Now I know from reading in the forums an my own experience that when the A/C compressor starts running you hear an electric whirring sound. My question is... is it a cause for concern when the sound it makes seems different -- the pitch sounds lower to me now. The A/C still works fine, but I didn't know if this changing sound means the compressor was on the way out.
View 13 RepliesPrius (2004-09) :: Whirring / Roaring Sound From Front Driver Side
Prius owner. I have 200,000 miles on the car and have done nothing except change the oil, tired and battery. No other maintenance was performed.
While driving straight the front wheel seems to vibrate some and make a whirring/roaring sounds. When turning to the left the noise is greatly reduced. When turning to the right it still exists.
Any potential causes? Possibly the struts? They as well as all the front end components are original.
