Santa Fe (CM - 2007-12) :: High Pitched Humming Or Whirling From Dashboard While Decelerating
Jan 30, 2015
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.

I have a 2007 Camry with 90k miles. All of a sudden today when I turned my car on I noticed a high pitched whirling noise, similar to a tornado siren that gets louder as I accelerated in my parking garage. Even when I turned the car off and on and it sat in park I still noticed it and it got louder as I press on the accelerator. I haven't driven over 20 mph since I noticed this so I'm not sure if it still does it at fast speeds.

How is the turbo in this new design cooled? Sometimes when I restart a hot engine, there is a high pitched whirling sound before I take off. Is this the turbo in action? Are there active shutters in this car? Twin Power Turbo 2011 BMW 535i....

I drive a 2010 Golf Wagon/JSW, and when I'm going at speeds around +60 mph/90 kmph and lift off the accelerator a faint high pitched whirling noise comes on. As soon as I tap the gas pedal it goes away. What this could be?
It's been a week now since I've noticed this, I guess I've never noticed it before or it's getting louder..i don't know?

I have a 2008 Santa Fe LTD, and just recently started experiencing a strange noise when I am accelerating, and I cannot pinpoint it. Here is some info on the noise.
-2008 Santa Fe LTD AWD, about 25,000 miles
-Sounds like a little higher pitched hum, not very loud
-Seems to be coming from somewhere near the passenger side backseat area (first found out about it when someone was sitting there and asked what the noise was)
-Cannot tell whether it is coming from the interior or exterior of the car, but I think exterior, but it is definitely somewhere along the passenger side, from the back half of the car.
-Noise occurs when accelerating from a stopped position, only when accelerating, never when braking or idle.
-Noise occurs only when car is in gear (hitting the gas pedal in park does not cause the noise to happen)
-Noise doesn't occur at high speeds or when accelerating at high speeds
-Noise only really occurs for a 2-3 seconds while accelerating, then seems to go away as I continue to drive.
-Noise doesn't seem to always happen, but very frequently.

Started hearing a weird humming noise (not the usual hyundai hum in the front passenger side) coming from the front when decelerating from approximately 20mph down to a stop or from a stop up to 20mph. Went to a shop and ruled out wheel bearings, brakes, rotation, alignment, etc. Noise stopped.
Couple weeks later noticed physical resistance and upon accelerating to about 40mph it felt like I had a flat tire. That bumping, vibrating, shuddering feeling. No flat tire. Physical resistance, not power. Came and went in severity depending on terrain and speed. Brought it to a 2nd shop because the first was closed. The guy found codes that indicated the anti-lock brake system had failed. Said it should be covered under warranty and I should go to dealer.
Dealer replaced a brake switch (which has been recalled and was replaced before) and an inhibitor switch. They assessed the brakes too.
Car drives fine for a week and suddenly the brakes are screeching and we can't reverse out of a parking spot like the car is stuck on a snow mound but isnt. Rock it- in and out of forward and reverse to get out. We test it putting it in reverse again and car slams to a stop. When the car was pulled up on the tow truck we noticed only the rear driver tire didn't spin-locked up.
Dealer says no computer codes and that they just had to "adjust" the brake switch they had replaced. Drove home fine. Next day and for these next few days-something is still wrong. Physical resistance, not power. Cracking/popping noises when braking.

I'm getting a vibration through the floorboards when I take my foot off the gas at high speeds. It has a low-pitched (like a subwoofer) hum to it. It's amplified when I go over dips and the suspension compresses, but doesn't exist when the car is in neutral.

Just picked up my car from the shop last night. Had a full tune up, air filter replaced, radiator upper hose replaced (was leaking), transmission service and an oil change. When I picked up the car at night I heard that it sounded a little off when starting but I was so excited to have it back that I drove it home. Once I was on the freeway, no weird noises and it drove perfectly fine. This morning when I started it up again the sound was there again. I can only explain it as a sort of high pitched humming. I pulled away from the curb and it made more noise - I heard that sound once when I needed power steering fluid. I put the car in park and popped the hood. Power steering fluid was full. My mom suggested I restart the car so she could hear the sound. This time when I started the car it sounded fine. Typical.
I drove it to work and it drove fine and never made that noise again.
(car is a VW Passat 01')

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?

My Prius IV with about 10K miles started to emit a high-pitched electrical humming sound under the hood when it was in Ready mode. It did not have this sound before. I opened the hood and found the sound was coming from somewhere around/under the engine area. I want to know if this is normal on Gen 3 Prius? I have seen post on the same noise in Gen 2 Prius but the posts (thread) stopped without a resolution.

I have a 2002 Honda Civic EX with 146,000 miles. It started making a whining/high pitched humming type noise whenever I turned. Every now and then it makes the same noise (though not as loud) when I'm just driving straight.
When I checked my power steering fluid, it was low, so I added to it. That worked with the noise briefly, but now it's back and the fluid level is fine.

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?

This has begun in the last few weeks on my '02 SF (which only has a couple of months left until it is retired )....
If I'm going anywhere between about 90-110 KM, I'll hear an odd high pitched whine. It sounds almost like microphone feedback, and I'm having a really hard time trying to find out where the sound is coming from. It is very subtle and comes and goes.

My wife's 2006 Prius is having some problems. The car has 187,000 miles on it. When the engine starts it makes a continuous whirling or humming sound. WHen I try to drive it has minimal power and can not be driven above 15-20 mph on my street. I bought an inexpensive Actron code reader and got the following codes. P0A92 P0300 P0303 P0304 P3191. Does it sound like a definite transmission problem and those other codes are caused by the transmission problem.

So I've started hearing a faint high-pitched noise when I apply my brakes. It's not EVERY time I apply the brakes, and it's not nearly as loud and annoying as the noise I hear other vehicles make when they need their brakes checked, but it's noticeable.
Also: There's a (possibly related) scratching/rattling noise that just started. I can only hear it with the windows down and it's not very loud. But it happens intermittently when the vehicle is moving or when it's braking, and it makes an almost sputtering sound when I slow to a stop. It will abruptly go silent before I'm fully stopped. Sometimes it cuts in and out, similar to when you've got a short in a speaker wire and the sound cuts in and out.
I'll be getting this checked out. Is this a "drop everything and go to the mechanic" issue, do you think, or more of a "get it looked at when you can"? I should note I haven't had any problems with the car actually braking (yet). It seems to function fine other than the new noises.

First I noticed that the parking brake light and battery light came on, which would indicate an alternator problem. I took it in, they cleaned up the engine, replaced a few hoses and said the alternator was fine. Two days later I'm driving home, I make it to my driveway and the battery dies. I was able to charge it up and dive it back to the station where they told me the alternator had burned out...
A few days later I notice my brake lights weren't working, but that was just a blown fuse.
Starting today, there is a high pitched whine when I'm driving. I can barely hear it when I'm idle, but going up to 20 or 30 it gets very loud, then kind of dies off. It definitely gets louder when I'm accelerating, vs going a steady speed. As I was driving earlier, the air bag light came on for a brief second, and I didn't think anything of it, until later tonight when I was driving home and it came on again, but this time it stayed on.

Just had 4 new rotors put on my '08 LWB after 70k miles. A few days later, I noticed a very high pitched whine that occurs occasionally at speed. When I brake, it stops, and it restarts a few minutes later. It almost sounds like what you detect during a hearing test, only louder. And before you ask, passengers can hear it too.

I purchased a 2014 LWB six weeks ago. The vehicle runs great. For the last three weeks, I hear an unusual high-pitched sound when starting the engine for the first time that day (temperature between 40-60F). See videos below. Ride height is set to normal, so I don't think it is the air compressor. You may notice that the whine goes away when the idle rpm falls from 1500 on the first start.

I get a very annoying high pitched electronic whine on an AM radio station that I like. It occurs all the time. Its like a grounding problem. It is so bad I can't listen to the station in my 2009 LS. Only one station, AM 810, has the issue. I don't have ML. Just a regular radio. No other radio issues.

I've got a 2007 pontiac grand prix that I picked up off a guy for $900 and so far it's been a head ache. So far, I've had to replace the power steering pump, pump lining, there's a hole in the radiator, and now a mystery problem that me and my lack of car knowledge can't diagnose.
Smoke/steam (smells burned) is coming from behind the engine and when the wheels are turned, it sounds like a high pitched grinding noise. I checked the oil, its fine. I filled the radiator with water as a temporary fix until I can afford to get the radiator fixed or repaired. Air conditioning only works on max setting. Before the problem occurred, I was pouring water into the extra reservoir when my friend started the car. Maybe the radiator sucked up some air while I was filling the reservoir.

I'm getting a very ugly high pitched screeching sound from my belt when the car has been sitting for 3 hours (cold start), or randomly when I turn my steering wheel. Based on that what does it sound like the problem is?
