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.
View 6 RepliesI 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....
View 5 RepliesI 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.
View 1 RepliesMy 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.
View 3 RepliesI have been hearing an intermittent high pitched squeal at 50 MPH and higher. Taking my foot off the gas or taking it out of gear doesn't change the noise. Hitting a bump or tapping the brakes makes it stop momentarily. It sounds like it is coming from the front driver side, though it's hard to tell.
I have about 33,000 miles on the car. My manual says that the brake pad replacement indicator should squeal when the brakes are applied.
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.
View 3 RepliesThere 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.
View 6 RepliesAlright I did a search and found these threads with no final resolution on each. My new 2013 has the whistling noise at high speeds (65+) and high winds. It's for sure not from the engine and coming from both the driver and passenger mirrors. I can hear it with either or both front windows down but not back windows. No whistle at idle or due to high RPMs. What is the Jetta TSB # or a fix for this issue.

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.
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.
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.
View 5 RepliesHigh 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.
Having problem on mrk 6, sounds almost like a high pitched vacuum leak but I can't find it.
View 11 Replies97 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.
View 4 RepliesMy 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 RepliesSo 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.
View 4 RepliesI have a 04 v6 model , in the last couple of months when I am on the interstate at about 75-80 mph. I get a very loud vibrating noise coming from the rear of the vehicle. The dealer thinks the drive shaft has some play in it.
View 6 RepliesI've noticed that at speeds of 60+ (especially 65+), the Prius control doesn't seem "tight." I wouldn't go as far as saying it has a "shimmy" but it's harder to keep straight on the highway. I absolutely adore my Prius but this bothers me. I had the alignment checked and it's perfect. I know all small cars tend to be less grounded than, say, an SUV, but I'm still curious if this is normal before I take it into the dealer.
View 15 RepliesWhen I am driving, especially at high speeds on the highway, the Navigation System on my Prius runs pretty slow. As the GPS icon is traveling, the movement is very choppy. It is not a smooth transition. Is there any way that I can fix this?
