Prius (2004-09) :: High Pitched Squealing Noise From Front Driver Side At Above 30 MPH In Cold Weather

When it is cold (below 30 degrees) and above about 30mph, there is a loud high pitched squeal (rather like the pitch of a squealing hearing aide)that seems to come form the front drivers side. The colder it is, the louder it is.

When I am able to take it in it is too warm to hear it. What might be causing the noise and will they be able to figure it out if it isn't making the sound?

Subaru - Outback :: 2005 - High Pitched Whine When Car Is Cold And Around 20 Mph

About 2 months ago, I noticed a high pitched whine on my 2005 Subaru Outback. It honestly sounds like a siren and is very noticeable. It occurs more often when the car is cold (1st thing in the morning) and around 20 mph. It sounds like it is coming from the rear of my car. It occurs whether or not I am pressing on the gas pedal. Once I get above about 30-40 mph, I don't notice it anymore (don't know if this is because other engine noises are drowning it out or what). It does not change or get worse when I turn. It seems to subside once my car is warm. Other people have heard it and some describe it like an airplane taking off.

I took it to the Subaru dealership and they said it was my alternator. Lo and behold a few hundred dollars later, it was still making the noise. A few days later, my CAM sensor went bad and I was back in the shop. Of course, I tried to get my car to make the noise for the mechanic, but it wouldn't cooperate. They didn't see anything wrong, but it is still making the noise. I have taken it to the dealership and they couldn't get it to make the noise. My rear wheel bearings were going bad and so I replaced those - under warranty, but it still makes the noise. I keep up with all my oil changes, services, etc. I just had the fluids checked and the power steering fluid is normal. The power steering pump has also been checked and it is normal. What this might be?

Ford F-150 (2004-2008) :: High Pitched Squeal Coming From Engine Compartment

I just bought a 2006 F150 SuperCrew with a 5.4L engine and since the weather has turned cold, I've noticed an intermittent high pitched squeal coming from the engine compartment. I've replaced the serpentine belt and the idler pulley plus another belt pulley but none of the above worked.


I've also had two separate mechanics look at the problem and both are at a loss as to what could be causing the noise. The guess is maybe its an air leak coming from either the intake or vacuum lines. But nobody is really sure.

The noise seems to really become noticeable when the temperature gets below 20 degrees and around 2000 rpms, but sometimes it happens at other times. Where this extremely annoying sound might be coming from?

Jeep - Cherokee :: 2000 - High Pitched Whistling Noise In Cool / Cold Weather

My Jeep makes a whistling noise in cool/cold weather (~60 degrees and below) that no mechanic has been able to diagnose let alone fix the problem. Here are the details...

-high pitched whistling (can be heard inside and outside the car - very loud) only when temps are about 60 degrees and below-after 5 minutes of the car running-only when RPMs are about 2.0 or below.

However, RPMs can be higher when it is colder out and it will still make the noise-as you push on the accelerator, the noise gradually decreases until RPMs are high enough to completely stop the noise.

When temps are around 50-60 degrees, sometimes the whistling will stop after the car has been at a complete stop for about 1-2 minutes-If you turn off the car and let it sit for 1-2 minutes, then turn it back on, usually the whistling will be gone. It will need to sit in the off position for longer the colder the temps are. This problem has been ongoing for about 4 years.

Subaru - Outback :: 2009 - Squealing Noise From The Engine When Car Started

2009 Subraru Impreza Outback Sport (60K miles).. I'm trying to figure out what's wrong with my clutch. When I start my car I hear a squealing noise from the engine that sticks around until my car is warmed up. If I depress the clutch while it's warming up (and squealing), it goes away. Bearing?

Subaru - Forester :: High Pitched Squeaking Noise Coming From The Area Near Front Left Of Car

What is causing this strange noise. I have an old 1998 Subaru Impreza that runs well but has this mystery squeaking noise coming from the area near the front left of the car. It seems to happen most on cold, dry days, and I can hear it when the car shakes, but only when it is driving, never at rest. I can usually make the noise if I let up on the gas while still in gear, and it happens sometimes while going over bumps, but typically only if the bump only affects one side of the car. If I am accelerating quickly or braking, the noise usually doesn't happen. It also usually only happens when I am in gear and have the gas pedal pressed, but it can still happens on bumps even if the car is in neutral, the noise is usually much quieter if the car isn't in gear.

I can't tell if the noise is coming from inside or outside of the car, but it seems to be louder inside and I can't hear anything from outside when driving through a parking garage with my windows down.Now this noise first appeared a few days after I got my clutch plate, fly wheel and axles replaced several months ago but I haven't been able to find anything on my own and the shop said they didn't see anything that could be causing it.I have included a recording I took while driving, if you listen its the high pitched squeaking. So far the only thing I have done is checked the sway bar and bushings and those are all in good condition and covered in lube.

Subaru - Outback :: Exhaust Smell In Cold Weather When Idling At Stop Light

Whenever the temperature is below 20 degrees F and am idling at a stop light, if I have the heater fan running I get a horrible exhaust smell inside my car. I have discovered that I can lessen the bad smell by turning off the fans when the car is idling and then turning it back on when I start to drive.

Subaru - Outback :: 2002 - Metal On Metal Rattle With A Very Slight High Pitched Whistle

Yesterday, I noticed a rattling sound coming from the entire car a 2002 subaru outback 2.5l 4 cylander (it seems a bit louder on the passenger side but it literally can be heard throughout the car). I was on the expressway and got off and stopped at a red light when the check engine light came on and started to flash and the rpm's dropped rapidly and the needle began to bounce up and down. I pulled into a gas station to check it out more and popped the hood to find that when the car is rattling it is also shaking and rocking the engine of the car from side to side slightly.

When I'm idling the rpm's drop and the car feels like it is going to stall out. Then, as I accelerate, the rpm's barely go above 2000 and jump up quickly between 3000 & 4000. It sounds like a metal on metal rattle with a very slight high pitched whistle and you can hear a fan kick on and the engine try to keep the rpm's up every couple of seconds when the car is stopped. I had the timing belts replaced 2 years ago and it sounds very similar to how it did when they needed to be changed, however, the engine never felt like it was going to stall until yesterday.

When idling the noise gets louder and when accelerating it can still be heard but barely. Also, the rattling has caused the entire car to vibrate all of the time. I noticed yesterday that the oil was low and topped it off, but I don't think that would cause such a hige issue so quickly. When I go uphill, i have a good amount of power but every 30 second or so the car shifts and the rpm's jump lurching the car forward because of the surge of power. Also, when I hit the brakes, my rpm's jump slightly to about halfway above the 1 but the engine does not accelerate.

Ford F-150 - 1997-2003 :: High Pitched Backfire In Engine Compartment And Trans Not Shifting

1991, F-250, automatic, 150,000 miles, two tanks. Used mostly for towing an RV plus some pleasure. Not in daily use. A month ago I parked it and a few days later cranked it up and found it wouldn't run over thirty MPH. There was some high pitched backfire in the engine compartment and the trans. wouldn't shift. I parked it and the next day it wouldn't start. When I turned the key on the fuel pumps (either tank) ran continuously. Towed to a garage (I am not a Mechanic). They have replaced the fuel pressure control, checked all pressures and it still won't run right. The problem is intermittent. My tranny man said the trans was good. My mechanics don't know what to do. I bought it in 1998.

Camry :: V6 - High Pitched Ringing Noise Coming From Engine

I have a high pitched ringing noise coming from the engine and I can't figure out what is causing it. The only thing I can recall is that it started happening after I changed out all the spark plugs.

This is the area it is coming from...

Attached is a link to the video and sound of the noise [URL] ....

Camry :: High Pitched Whining Noise Coming From The Engine Bay

Turned my car (07 SE v7 with 240k on the clock) on this AM and there was a high pitched whine coming right from the engine bay - matched to the revs of the car, regardless of gear.

This is a new noise to me and the car - but I'm assuming it's some kind of belt issue.

Rodeo :: 99 - Intermittent High Pitched Squealing Noise At Highway Speeds

I just purchased a 99 Rodeo 4X4 with the 5-speed stick. It makes an intermittent high pitched squealing noise at highway speeds. This noise comes up through the floor right about where the center console glove box is. In fact, it really sounds like it is coming from the console glove box.

Phaeton :: High Pitched Squealing Noise Every Time Depress Brake Pedal?

So - I'm sitting at my VW dealership, hoping that their can figure out why I'm getting a high pitched, miserable squealing sound, every time I depress my brake pedal. It's metallic sounding, and with the history of brake issues I've had in owning other VW models, I just figured it was the brake pads they use. Sounds like their tech believes it is an issue with the tires??? I've got an 04 Phaeton with roughly 38K miles on it - and it's supposedly "certified"....

Hyundai - Elantra :: Intermittent High Pitched Squealing Noise At Highway Speeds

My girlfriend's Elantra (mid 90s model, I think) makes an intermittent noise when on the highway. It sounds to me like it could either be from friction or some sort of wind noise, but I suspect it's the former. It only seems to happen at speeds above 50 or so. When it occurs, it is always the same pitch and loudness -- these don't seem to vary. It's rather loud, to the point where it is pretty unpleasant to drive when this is going on. It has happened both when my foot is on and off the gas pedal. When the noise happens, it can last anywhere from just a second to up to a minute or more. I haven't been able to identify anything obvious that it's correlated with -- wind direction, grade of road, etc. The only thing I do know is that it only seems to happen at highway speeds. We never hear it during city driving. So far one mechanic has confidently misdiagnosed the problem as a bad wheel bearing.

IS F (2008-2014) :: High-pitched Hissing / Whistling Noise Coming From Engine At 1500 RPM

Usually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.

I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..

I have a Takeda intake installed and I re-tighten the fittings.

Toyota - RAV4 :: Medium Pitched Whirring Noise From Passenger Side Of Engine Compartment

So my girlfriends Toyota RAV4 (2005) is making a medium pitched whirring noise from the passenger side of the engine compartment. (Same area where the serpentine belt and the alternator and all those goods are located.) The battery warning light is on, solid. I have not had a chance to take my DMM and check voltage but I suspect this is going to be a bad alternator since it is a noise consistent with the RPM of the vehicle and visual inspection of the belt is that it is still in one piece, not frayed, flexible, etc. I didn't rev the engine because I didn't want to freak her (the gf) out. My plan is to test voltage before she does anything rash like take it to the dealership which she is already planning on doing but the noise concerns me since noises tend to come from things that move which is probably an indication of some sort of mechanical failure and that tends to cost money. Luckily it's her car.
