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.

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.

I have a 4 cylinder 2012 Toyota Camry SE. It is 3 months old and has 2,300 miles.
My husband and I notice a high pitch humming noise that happens mainly on the freeway, when you get over 45 mph. We tried ruling out different things like, bluetooth, radio, air conditioner, wind noise etc. We realized that the noise happens with you push on the accelerator pedal. If you hold the pedal to maintain speed, it does not happen. Only when you push the accelerator pedal. The noise was more noticeable when I drove it up in the mountains and had to push on the accelerator pedal off and on to maneuver turns and up hills.
I figure that we can bring it up to our dealer in October at our 5,000 mile service.
Camry 2012+ :: High Pitch Whirl When Heavily Accelerating At About 4000 RPMs
Is this normal for the Camry? When you're flooring the car besides the typical roar I hear like a small high pitch noise, it's gone once I let go of the gas. I tested it & start to hear it at about 4000RPMs I believe. Recorded it on video but you can't hear it at all on video.

I bought a 2002 accord with 105800 miles 3 weeks ago. I got the timing belt and water pump replaced within a week of that. I have noticed that the car makes a high pitch noise upon accelerating after replacing the belt. It does not happen always, but sometimes. I have noticed it on 3 days in last 2 weeks. A preliminary web search tells me that it could be a tight timing belt.
View 3 RepliesLexus GX 2004-09 :: RPMs Started Surging While Idle And High Pitch Humming Noise When Accelerating
My girlfriend has a 2008 with around 120k miles on it. It's been pretty flawless but yesterday the RPMs started surging while idle and made kind of a high pitch humming noise when accelerating.
Today on her way to work she said the radio was going in and out, the battery light lit up and then the rest of the dash lights came on, and the speedometer stopped working.
What could be the problem? Could it just be the battery?
Ford Escape / Hybrid :: 2001 - Loud High Pitch Whistle / Whirling Sound When Accelerating
My girlfriend has a 2001 Ford Escape 3L, 6cyl. When accelerating there is a loud high pitch whistle/whirling sound. The sound varies with the amount of throttle you give it. More throttle = louder whine. Doesn't seem to do it when idling or coasting. What that could be? I'm about to remove the belt and take a look at the drive belt tensioner and other pulleys.
Just checked pulleys and tensioner and the tensioner seems fine, a/c pulley spins smooth and free no play, alternator spins smooth no play. The belt needs to be replaced. I wouldn't think this would cause such a load whistle under acceleration. I would expect it to do it all the time if it was the belt. I'm looking at the water pump pulley and belt too and they seem ok as well.
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.

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 (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.

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.

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.

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).
