Subaru - Outback :: High-pitched Squealing Noise Coming From Engine Compartment In Cold Weather

Need to determine the cause of a strange high-pitched squealing noise coming from the engine compartment of my 2008 Subaru Outback 2.5l automatic. The squeal happens only when the temperature is cold (below 32 degrees) AND I hit a bump. It happens more often the colder it is outside. The noise is definitely coming from the front of the car and seems like the passenger side but I can't be sure. It happens with the blower fan/AC both on and off so I don't think it is caused by that. It happens when the car is cold or driven for a while and warmed up.

It occurs at both high & low speeds. I checked all my fluids under the hood and everything is filled as it should be. There are no lights (check engine or ABS) on. Recommend any troubleshooting that I can try? I have not taken it to a mechanic yet as they might have a hard time reproducing the noise since it has to be below freezing and hit a decent bump. I attach a video that I took while driving last week on a 16 degree day and heard the squeal when I hit a bump. I had been driving for about 30 min when it occurred. I have more videos of the noise if needed.

Prius (Gen 2) :: High Pitched Squealing From Passenger Side

I was driving home from work tonight. It was a rather windy and rainy drive home. Anyways, I started to notice a high pitched squealing from the passenger side. I couldn't tell if this was from the window or coming from a vent.

I tried to slightly crack the passenger side window. The sound wasn't too loud, but just wanted to make sure it wasn't something major.

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.

Prius (2004-09) :: ICE Rev Abnormally High During Very Cold Weather

I have an 05 Prius with 108k miles I bought about 2 months ago. My commute to work each morning is 1.5 miles with speeds of 25mph or less.

Usually the car has acted the same way each day. The ice spins consistently as I creep along to work. But last night the temps dropped to -10f and this morning when I left for work it was about 3 above. I turned on the car and instead of the few seconds after ready it takes for the ice to turn on it turned on right away today. I let it warm for about 3 minutes then set off. Right away I noticed the ice start to Rev up.

And as I slowly approached 25 MPH it was revving abnormally high. It was showing energy from the ice to the wheels and to the mg and charging the battery which was at the normal state of charge. All blue, right before green. When I stopped at a light about 1 mile in the ice turned off as normal, and started right away as normal. But it seemed the ice was still revving as if it was working very hard to pick up a slow increase in speed.

I pulled into my parking spot, battery showing green state of charge now, and the motor stopped as usual. I do not run the heat on this trip and it takes usually 5 minutes, so I just tough it out.

Prius (Gen 2) :: Driver Side Mirror Heater Stopped Working In Cold Weather

Well, as the cold weather has approached, a minor issue has surfaced.

It appears my driver-side mirror heater is not working. Both mirrors still move as they should, and the rear defroster and passenger side mirror both heat as the should with the defrost button, but the driver side does not, as it is cold to the touch and naturally did not melt the frost yesterday.

I looked at the fuses hoping it would be something as simple as that, but it does not appear there are separate fuses for each mirror; the naming is a bit cryptic, but it looks like there may be one for both mirrors, which logically would not explain the situation.

Seems to me the heater itself is defective, and I am not exactly looking forward to opening up the mirror and/or spending money to fix this...

The Prius is a 2006, and I am up to 256K KM (~160K miles) to date.

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.

Ford F-150 (2004-2008) :: Front 4x4 Hub Binding / Squealing From Driver Side

I have an 07 f150 base model truck, manual 4x4 no push button. It seems something is binding in the hub once in awhile. I am driving down the road and all of a sudden i hear a loud squealing from the front drivers side. I slow down and then something seems to engage when I am almost stopped. I did a little research and have come up with the actuator might be bad. I just don't wanna throw parts at it that it don't need. Here's a lil more info. Last winter I put it in 4 wheel drive and the passenger side was making the same noise with the 4x4 not working when I hit the gas. I am thinking actuators need replacing on both sides.

Elantra MD (2010-15) :: Squealing Noise From Front Driver Side Wheel Area

About 6 weeks ago I noticed a noise coming from the front driver side wheel area. We had just gotten the tire rotated and once at freeway speed it was like a squealing noise, just like when you have worn brakes. Since then the squealing noise is gone and now it's a faint (hard to describe over text) "whomp whomp" noise as if I have off-road tires. I notice it more on freeways I supposed because it's a smoother straighter surface. On a particular right bending street by our house it's louder. What it might be? Car has 36k miles.

Touareg :: 2004 - High Pitched Noise From The Right Front Wheel

My '04 started making a high pitched noise from the right front wheel within the last two weeks. It's in the local dealer now and they tell me they suspect a bad right front wheel bearing. I don't see any posts about similar experiences here. I kind of worry that the fact the vehicle is two years old and only has 9200 miles on it may be part of the problem-is infrequent use enough to cause the bad bearings? I drove it infrequently (1-2x/week, sometimes no driving for a week or two) up until the last three months, and now it's being driven daily.

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.

Prius (2004-09) :: 2008 - High Pitched Woo-woo Noise During Acceleration

I took my 2008, 56k in for a new battery after my car sat outside in negative degree temps for a few days. After doing that repair, the dealer recommended a new serpentine belt. Ever since that service appointment, the car is making a high-pitched "woo-wooo" noise during acceleration. It's definitely a noise I've never heard before. I took it back to the dealer two days later; he had the service guy drive it and they both claim the noise is normal and just due to the cold. Is it the belt? Is it the cold? Am I losing my mind?

Prius (2004-09) :: Driver Side Front Wheel Loud Hum Noise

I have a 05 Prius. Developed a low hum noise some time ago. It now is so loud can't hear the radio. Sounds like a heavy agressive truck tire rolling down the road. When turning the steering wheel from right to left quickly, noise level changes. Does this sound like a bad wheel bearing and if so what am I looking at for repair costs?

Prius (2004-09) :: High Pitched Whining Noise After Turn Off And Restart

I know this noise is the Thermos Pump and it operates when I turn the car on and off. Question - is it failing - also a really annoying noise, but I'll put up with it as long as nothing's breaking.

Prius (2004-09) :: 2008 - Rattling Noise From Driver Side Front Wheel?

First issue started a few weeks ago. When turning left at a speed > 20mph or when turning wheel quickly I get a rattling noise, which is more prominent with the driver window down, so it sounds like it comes from the driver side front wheel, but not quite sure. It is fairly loud as I have had pedestrians look at my car when turning because they can hear the rattle.

Second issue started this morning but has persisted every time since. When the car is cooling down, we get that whirring noise, which I presume is thr coolant pump. That noise also happens now when I enter the car, and it is accompanied by a knocking noise as if somebody is hitting the outside of the car repeatedly. This is quite unnerving as it sounds like something is hitting the bodywork of the car. It stops immediately when the normal whirring stops.

I had the steering and water pump recall done in november last year, could this be related to that? Forgot ti add the car has done 49000miles....

Prius (2004-09) :: Awful Noise Coming From Front Driver Side Of Car - Mid Hub Assembly Stuck

I've had some awful noise coming from the front drivers side of my car. Determining the likly cause to be the wheel bearing, I decided to tackle replacing the hub assembly as a lovely weekend project. Things were going along ok - Removed brake caliper, removed the axle nut (that wasn't fun), removed the rotor (rather persistently stuck on, but it gave in the end), and then came removing the hub assembly itself. Had a rented hub puller, put it on, started tightening it down and tapping on the hub as I went. It was getting pretty tight on there (was starting to worry about the safety of the cv shaft), and then as I tapped on the hub one last time, the hub and hub puller popped off the car... I was elated, until I realized rather than pulling the entire hub assembly out, it had actually separated the inner track of the bearing from the outer track, leaving the wheel bearing and flange behind inside the steering knuckle.

So, here I sit, with half my hub assembly on the ground and the other half still in the car. How to get the rest of the hub assembly out, now that there is nothing to really pull on? I've tapped around on it for a couple hours, and soaked it in enough penetrating oil to make the car flamable, but no give. I've even tried putting the hub bolts back in through the back and tapping on them with a hammer to no avail (probably going to have to replace the bolts now, but one problem at a time).

Golf IV R32 :: High Pitched Noise On Cold Start

It's been pretty cold here and haven't started my R in 2 days at the most. I turned it over this morning and got this high pitched noise, like maybe a belt slipping or a bad bearing? The CEL flashed a few times then went away.

I couldn't stick around to check codes or inspect the bay, but what it might be?

Camry 2012+ :: SE - High-pitched Whine From Front Passenger Side Of Car

I'm going to take my 2012 Camry SE in for service sometime in November and experienced a high-pitched whine (very low volume) in the front end of their car. This sound seems to be coming from the front passenger side of the car and has surfaced only within the last month or so, between 70-75 MPH. Above and below that speed range I hear nothing. This car has low mileage; after almost two years, it has only about 12,500 miles on it.

I'm wondering whether it's a trans-axle whine, but it is of such low volume I don't think it would be easy for a tech to diagnose. Also, other than the D1T recall, are there any other TSBs that I should be aware of, and any recent Entune updates that need to be applied? And, whether Toyota has a remedy for D1T yet?
