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.

Prius (2004-09) :: High Pitch Squeak / Whistle While Accelerating And Braking

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.

Prius (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?

Lexus - Es300 :: Low Pitch Growling In Reverse / High Pitch Screech When Apply Brakes

I have a 1995 Lexus ES300 with 130,000 miles on it. When I reverse, I get a low-pitch growling and as as soon as I apply the brakes by a high-pitch, ungodly screech. This noise is definitely coming from the rear wheel areas. I'm not sure which tire is the culprit (I hear both sides from while listening from both the inside and outside). It happens frequently but is particularly bad on rainy, snowy, misty, or high humidity days. Two years ago I replaced the pads and rotors. At this point, the pads look to have about 40% life on them yet. This problem started happening about a year ago.

My initial thoughts were that it was just rusting because of the frequency on high moisture days. But both noises are way too loud for that. My second speculation was that the emergency brake was catching, but after examining it I think not. I've taken the entire assembly (brakes, rotors calipers, and emergency brake) at each tire apart and looked for any obvious issues that look incorrect. No luck. I've also applied brake quiet with similar results. Now my thoughts are that the low pitch is the rotors being warped. But that doesn't explain the screech and why it only occurs in reverse.

Prius (Gen 2) :: High Pitch Noise From Transaxle During Acceleration

I have a 2007 Prius 3 Touring Edition. I purchased it new in Dec. 2006. I have had NO issues with my favorite car of all time, and currently have 90,600 miles. I have noticed a high pitch for a long time coming from the transaxle during acceleration. The pitch is only present when MG1 or MG2 is engaged. The pitch stops in stealth mode. My finance also has a 2007 Prius, and her's does not make the noise or whine when I drive her vehicle.

I have changed the transaxle fluid at 65,000 miles, but I did not see the plug when it was changed so I don't know how much, if any, shavings were stuck to the magnetic bolt. If you are wondering, yes, the high pitched noise was present before the fluid change. Also, as I accelerate and increase speed, the noise pitch increases.

Is my transaxle displaying a tell-tale sign of imminent failure?

Prius (Gen 2) :: 2009 High Pitch Noise At Low Speed

I have a 2009 Gen. II with 48000 miles on it and it started having a high pitch noise when driving. Thought it was wind noise at first but does it at low speeds also. When you roll the right passenger side window down you can hear it much louder sounds like it is coming from the right front.

Prius (Gen 2) :: Faint High Pitch Whine When Braking

During around town driving I am experiencing a faint high pitch whine when braking. This sound is not mechanical, but more electrical coming from the dash-engine area. It is very noticeable when slowing between 40 mph to 20mph.

Prius (Gen 3) :: High Pitch Chirp Occasionally When Accelerating Between 25 - 30 Mph

Recently upgraded from an 05 Prius to a 13 Persona Prius. Loving it! The 13 was used and it had about 17k miles. What I have noticed, and still learning all the new stuff on this gen 3, but while testing out power mode driving in town, occasionally I will get a high pitch whistle while accelerating after its reached maybe 5mph.

The high pitch sound lasts only a few seconds and if I take my foot off accelerator it immediately stops. Sometimes it does it again when I tap the accelerator again but stops after just a couple of seconds and speeds are up past maybe 15mph.

Weird? Never heard anything like on my 05 ever.

Civic - Honda :: 2004 - High Pitch Noise When Accelerating

My Civic started to make high pitch noise when turning right or left, and also when accelerating. It makes more noise when I keep the wheels turning but ceases the noise when I let the handle go and go straight. When accelerating, it ceases the noise as it reaches 30 mph or so. It has got 93000 miles on it. It started the noise about 10 months ago and I feel like it increased the noise over the time. I don't drive everyday and I try to drive my wife's Prius when I drive since it has better gas milage. But this noise is quite annoying and wonder what it is.

Touareg :: 2004 - Brakes Squeaking / High Pitch Sound?

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 (Gen 3) :: High Pitch Coming When Having Driver Side Window Down

I have a 2013 Prius. I was noticing a high pitch coming that I could hear when I had the driver side window down and the sound was reflecting against things I was driving by. It was strange because it didn't change pitch at different speeds, and it would be there most of the time regardless of whether I was speeding up or slowing down. And regardless of whether I was using the brakes or not. I've been told this is the sound of the inverter.

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).
