Subaru - Forester :: High Pitched Whistling Sound Comes Out Of Dashboard / Vacuum Leak
Aug 2, 2014
My mother, who is retired, has a Subaru Forester, probably a 2001 or thereabouts. It runs great, but recently whenever you let off the brakes, there is a high-pitched whistling sound that comes out of the dashboard on the driver's side. My mother claims that she took this to a mechanic and they told her that there is a small vacuum leak in the power brake line. They also told her that the leak was small and that there was no hurry to fix it (that was in April). Now it is August and my mother is still putting off fixing it because of the cost. They will have to pull out the engine and the dashboard to get to the leak. In the meantime, she continues to drive the car saying that the worst that will happen if it fails is that the power brakes won't work, but she'll still have her regular disk brakes, she'll just have to mash down her foot a little harder. Is this safe?

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.

I finally got a recording of this, after trying to describe it without much success. Dealer drove the car 2x and claimed they don't hear it.
Video here, turn up your sound... noise happens just as the gas is let off...
As you can hear (if you turn speakers up, recording isn't very sensitive), it's kind of a high pitched whistling sound or whining sound. Happens when coasting (foot off gas) at 60mph. In gear or neutral, same noise. Only around that speed, only when foot off the gas.
What do you think this is? Some have suggested wheel bearing but if you listen this is more of a steady high pitched noise, not a helicopter like sound.

High pitched noise when car is running at idle and when not on the gas. Whenever I accelerate it goes away. Pitch/Loudness seems to be higher with RPM's. Could be coming from front of the car.
Checked so far:
I read some other posts about this and fully disconnected my aftermarket radio. I'm pretty sure it is not a ground loop as no power to HU shouldn't still create the whistle.
What I have:
I have an EIP aftermarket street exhaust. I checked the exhaust to see about the flapper, but I don't believe I have any of the items involved - maybe I'm wrong. After some more reading it sounds like a vacuum leak as it goes away upon acceleration. I need identifying what vacuum hoses are still in place/clamped off with having an aftermarket exhaust.
I do not have a CAI, just a K&N drop in.

97 Sierra K1500, 5.7 liter. High pitched whistling sound underhood in the vicinity of the throttle body. Starts after truck warms up and quiets down when accelerating. I've wiggled hoses, disconnected what I could without stalling engine, checked air lines into throttle body, checked air filter, etc. Sound does not change when I apply brakes so I don't think it's related to master cylinder. The only time it changes is when I accelerate, then only gets quiet until I come back to steady speed.
Truck has 85,000, runs great. No codes.

I have recently noticed that there is a loud, high-pitched whistling sound coming from under my hood that has progressively gotten worse over the weeks. At first, it would only occur when I had my AC or heat on and would stop immediately once i turned the AC/heat off, and will also happen from time to time when I accelerate. Now, this noise is happening right when I start my car and takes a few seconds to stop.

So I noticed when it started getting cold that my Jeep emits this extremely high pitched whistling sound and I can't figure out what's going on. I've taken it to two mechanics and both said it was a belt that needed to be replaced so I had the belt replaced and the noise persisted. I've noticed a few things about the noise, it only happens when it is approximately 30 degrees outside or lower; only while the car is idling (when I accelerate the noise goes away immediately); It only happens after I've gone above approximately 30mph; The noise will go away after I've gone through a series of idling and accelerating; and stops immediately once I turn the car off. The Jeep is almost up to 150,000 miles.

Car suddenly started a high pitched whistling noise/metal on metal sound at highway speeds. It is intermittent, no noticeable pattern w/acceleration or braking. Similar sound at lower volume when the shock/spring is depressed (pushing down on that corner of the car). Louder at low speeds.

Very high pitched "whistle"(enough to give you a headache) as vehicle speed increases or fan speed increased. This will not occur on recirculate and will go away if a window or roof is opened.

4601 DBP, just under 35k on it. At idle, i hear a slight whistling almost like squeaking. I took it to my independent tech and he showed me that if he removed the dipstick for a second while idling, the noise stopped, due to lack of vaccuum, so he believes its in the pcv system. I am still under powertrain and obviously federal emissions 8yr 80,000. Go start your R and listen at idle inside the car for a whistle or squeaking noise that seems like its inside the passenger dash.

Got a tire rotation a two weeks ago on my new 2013 Kia Forte (purchased in August 2012).Now, I have a very high pitched whistling noise coming from the rear tire area. The sound happens at all speeds. The sound is the worse at very slow speeds; the sound is also very bad at very slow speeds when I touch the brakes and turn the wheel.I looked at back tires from outside the car (not underneath the car). The mechanical set-up of back tires look very different than that of the front tires. The back tires have metal parts touching each other while the front tires do not.

I seem to have this high pitched whistling noise as I am driving at normal speeds (starts at ~40-45 mph). It seems to coming from my rear drivers side, but I'm not entirely sure. My R has about 78,xxx miles and I haven't done this 80k....

There is a whistling noise that is coming from under the hood of my Jeep. It is more noticeable on cold days. It temporarily disappears when my foot is on the accelerator or after I have been idling at a stop sign for 30 seconds. The noise starts again when I start driving.

My 2012 Accent Blue is making a low pitched whistling sound when its in motion. I have an annoying problem with my car. While I'm driving the car whenever I pass 90 km/h a whistling noise are started in front of my car. Hyundai Service nor Hyundai Customer service come up with a solution. They say just go an another service an check it. I uploaded 2 videos :

My car is making a sort of whining noise; it sounds like some sort of tire noise, but I checked the tires and don't see anything that could be problematic. My husband checked to see if anything was rubbing, and doesn't find anything. The car is quiet when it is not moving, and the noise gets somewhat louder and slightly higher-pitched as I accelerate. It almost seems like the noise changed on a different road surface, but again, I don't see anything different with the tires. The car has about 140-150,000 on it. The noise has only been noticeable for a couple of weeks. No other problems, no change in steering or handling. No incident that I can think of that could have been a catalyst.

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.

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.

Every time I hit a bump, even a small one, I get a high-pitched rattle from the center of my dashboard that sounds just like a cricket chirp. I'll bring it up when I visit the dealer for a courtesy check-up, but Was it diagnosed and repaired?

I am slowly coming up on my 3 year anniversary with my Santa Fe 2007 3.3 AWD transmission , and after 50,000 trouble free miles I've encountered a problem.
It started this summer when I was towing my trailer on about a 300 mile journey. It sounded like a high pitched humming or whirling from the dashboard, while decelerating. It would stop at around 15 MPH. You cannot hear it while cruising. After days of head scratching I determined that the noise is coming from the transmission. It comes from the output side, as it shifts through all the gears smoothly, however it makes the sound with the engine off while coasting with the transmission in neutral too.
I noticed the transmission fluid was slightly burnt. As I am student, the problem was solved by turning up the radio, and as the car shifts great no thought was given.
During Christmas break I drove the car out to the west coast and about 400 miles into the journey the whining really got loud and frankly freaked me out. The car now sounds like little aircraft jet engines whinding down when you decelerate. OK its not as loud but when you're 400 miles into a 1600 mile trip you tend to get panicky about such things.
The car made it back fine. It still shifts great except for the whiney turbine noises that disappear below 15mph. I've got transmission fluid so I will start today by doing a couple drain and fills, but I suspect that since I've been a bit too lackadaisical about the problem that will not be sufficient.

My son has a 2001 Subaru Forester that has a 5 speed manual transmission (transaxle) that is leaking from the drive axles . The question is how difficult is it to change these seals?
