Passat - Volkswagen :: 2001 - High Pitched Humming On Start Up
Jan 25, 2014
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.

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.

2003 Jetta station wagon, disc brakes all around.
Recently changed all 4 pads + the rear rotors. about 2 weeks after this the car started making a horrible noise from the rear driver side wheel- like the tires were dragging metal.
We took off the wheel last night, replaced the caliper, and discovered one caliper bolt was missing. We think this caused the caliper to misplace itself and start riding the rotor. The caliper was also in pretty bad shape so we went ahead and replaced it because we had already bought the part.
Anyway, we put everything together, drove it last night a short distance, everything was fine.
Today after driving apx. 25 miles since the replacement, the car has started whistling. I'm not sure where the noise is coming from, but it only happens at higher speeds, and I don't know if turning affects it but it happens going straight. It is a cyclical type of sound and goes away when braking.
Note: when replacing the caliper, my dad did not use the little metal brackets because we couldn't figure out how to place them and didn't think we needed them. Would that cause this noise? Is that dangerous to do?
UPDATE: I've mislead you all! Upon further inspection the whistling noise is coming from the serpentine belt area. I had assumed that it was coming from the wheel because we had JUST messed with it, but I was wrong. Now I'm wondering what's going on with the belt!

My car occasionally makes a high pitched whine while driving it's very loud and very frustrating. I've come to the following conclusions: It only happens when the car is warm, it only happens at speeds above 40mph, it doesn't correspond to either accelerating or decelerating, it happens either way and in between. I've had people in the car while it's happened and the noise seems to come from the driver's side rear wheel. Sometimes it gets so loud and then gets even louder when I begin to apply the brakes, it's as if it starts screaming.
I've had mechanics take apart the complete brake system on every wheel and put them back together. They've put anti-squeal on the brakes to no avail. While driving the noise can come and go, with no apparent reason why. It happens in rain and on warm sunny days. Also, the noise seems to oscillate as if it is something that's spinning, I'd guess it's at approximately 160 beats per minute. This has been occurring for about a year, it was not this way when I got the car. No mechanics have ever found anything, but it's so loud! And so annoying and embarrassing. This can't be normal, what is it!?

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.

I have the most annoying high-pitched squeak/whine coming from my front left tire. For those who cant see the video, its making a high pitched, metal on metal noise... at all speeds... especially when making slight turns... my foot was not on the brake when the video was taken (coasting around the parking lot at around 10 mph)...

So it only happens when I start the car, I'm thinking its the starting needing to be replace. The car starts everytime, Just when it cranks it makes a the noise, but fires up right away. The noise is gone once the car is started.

2008 Volkswagen Passat 2.0T... I am trying to figure out whats going on with my car for a few weeks now. I have a few things going on and I am not if they are related.
First off I am hearing a odd noise now and then from my engine area. Its so hard to explain, but its kind of like when a plastic bag gets stuck to your car, a fluttery higher pitched noise (and it lasts only a few seconds). It happens now on heavy acceleration (almost always), normal acceleration and even sometimes at start up. Its mostly random and started awhile back but I use to only hear the sound every couple weeks. Now its daily.
Related or not I also have noticed this really bad lag with heavier acceleration, after lagging it then down shifts VERY hard before taking off.

Driving yesterday with A/C on & I start to hear this high-pitched squeal from the engine compartment. It sounds like an annoying cell phone ringing constantly.
It only occurs in motion under full or partial engine load (or in drive w/ PB engaged) with the A/C on. It's coming from the front of the engine compartment.

I have a 2002 prius with 147612 miles on it and a problem with my braking system. When I turn on the car the ABS and Brake light turn on and there is a high pitch sound that beeps continuously. Sometimes after a while the warning lights and beeping stop only to return a little while later. I can drive the car when the warning lights are on but i have to press harder on the brakes than normal to get the car to stop and the braking system feels looser. However, when the warning lights turn off I can brake as i normally do and the system feels normal. This problem goes on intermittently as I'm driving.
I took the car to the dealership today and paid $143 for a diagnostics and was told that DTC C1251 was retrieved from the diagnostic computer. The technician told me that the ABS Motor is bad and because of that the car thinks I'm skidding so the ABS shuts off. He recommended that I get the ABS Motor ASSY ( Part #47071-47010) replaced.
Also, I read a post to resolve it by flushing the brake fluid. I checked the brake fluid level in the cylinder and it is at the max level and there aren't any leaks. Would that be an option?

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.

When I apply my brakes I hear a high pitched whine. I thought the pads needed replaced, but upon checking them there appears to be plenty of pad left. What else could this noise be? It's only when I apply the brake that I hear this, I suspect it may be something with the brake line but am not experienced enough to be sure.

I'm completely new to hybrids. I have a 2001 Toyota Prius with 146k miles and its been running very good until some weird things started happening during the past couple of months. When I start it up, the brake light and abs light come on along with a steady high-pitched noise and grinding noise (sounds like ice being scraped). While the lights are on and the sounds are being made, the brake becomes very soft/"spongy" and goes down to the ground without much force at all (It usually always does this when I start it up and sometimes - but not very often - when I'm driving). Sometimes it all goes off and everything is normal again after about 10 mins, sometimes all day, and sometimes only after a minute or two (It usually does it on a cold start, but sometimes even if the engine is heated up, it does it).

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.

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?

I have a 2002 B5.5 Passat sedan. 140K.
Inside my passat, when I run my heater on #1 speed setting there is a high pitched squeak but it goes away on the #2 speed setting. It hasn't been a constant annoyance but enough to want me to fix it now. [URL]....................

So now that it is winter, I have started to use the heater in the car. It works fine for about 10 minutes until a loud high pitched noise starts. Sounds like something is grinding. Any clue what it is? Is so, how to fix it?

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.

On Sunday the high-pitched beep went off while driving, followed by the orange engine light to the left of the speedo needle and EMISSIONS WORKSHOP coming up on the computer.
Everything is normal. Revs are fine, temp is fine, no other lights come on. I checked the coolant and that is fine too. This happened about two months ago, but it stopped after a couple of days.
Could this be something like an O2 censor?
