Jeep - Wrangler :: High Pitched Whistling Noise Coming From Under The Hood
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.

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.
Touareg :: High Pitched Whistling From Fan Coming With Increased Speed
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.

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.

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.

Whilst driving on the motorway at the weekend I noticed a very load high pitched noise which seemed to be coming from the rear/centre underside of the car. It lasted for about 30 seconds and then went. It has happened before about two months ago and after the first instance I had the haldex and rear diff oil changed. On both occasions it has been very wet on roads with torrentian rain.

In the last few days there has been an intermittent high pitched whirring noise coming from the rear undercarriage of my 2009 Elantra with automatic transmission, at least it seems where it is more pronounced on the outside of the vehicle. The pitch is unaffected by acceleration or climate control changes. It just comes and goes at random. The temperature here has dropped considerably in the last week or so and seems to have started since then.

View 5 RepliesJeep - 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.

View 4 RepliesLexus GS 2013+ :: High Pitched Whistling Sound When Coasting At 60 Mph
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.
Golf IV R32 :: High Pitched Whistling Sound When Car Running At Idle
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.

View 11 RepliesSierra :: 1997 - High Pitched Whistling Sound Around Throttle Body
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.
Subaru - Forester :: High Pitched Whistling Sound Comes Out Of Dashboard / Vacuum Leak
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?
View 6 RepliesJeep - Grandcherokee :: 2002 - Extremely High Pitched Whistling Sound While Idling
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.

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.
