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?
View 2 RepliesMy wife loves her Mercedes 1999 320CLK. Low mileage (120,000), excellent interior and body condition. One problem. When she turns on the heater there is a very high pitched whistle that gets loud and then slowly tapers off. This repeats from time to time. Randomly there is a sound like a flap/door slamming shut. All sound comes from behind the dash. Also, from the dash behind the steering wheel area you hear a sound kind of like someone squeezing a plastic water bottle - plastic crackling sound. Our mechanic took a look at this and told us that some sort of hose was loose. It was reconnected and things got better for a little while....now its back. Once in a while this happens with the AC.

View 1 RepliesI 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.

A high pitched chirping noise comes from the front passenger side wheel ONLY when turning left and ONLY when it's below 40F. Goes away once it warms up.
Wheel bearing?
I started hearing loud fan like noise today. It stayed on for a bit after the car was turned off. I usually wouldn't mind lil bit of fan noise.. but this was horrific loud.. I'm guessing I just need to replace the fan.
View 11 RepliesWhile driving home tonight in the snow, about half away home I noticed the most god awful high pitched squeal sound coming from what sounded like the back passenger side of the car. The squeal was so loud it made me cringe. I couldn't really get any near 40 mph because I could hear it start and instantly it would become really loud and would only stop when I slow down almost completely and then maintain a speed around 30 mph. It's pitch black out so I couldn't conduct a real thorough inspection however a quick look over and I didn't see anything wrong.
View 22 RepliesThis is kind of an odd ball problem since I have not encountered this before, but every time I turn my wheels full left or full right and start moving a really high pitched squeaking sound comes from the front of the car. Is it bad alignment or wear sensors on the brake pads rubbing? the brakes have a lot of pad left so i find that hard to believe.
View 5 RepliesMy 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!?
Last night around 1:00, I was awakened by a noise I think was coming from my car parked below my window. It was plugged in at the time. I heard a loud, high pitched whine, followed by a couple of knocks or thumps, then a sound like R2D2 makes when he turns his head, then a couple more knocks, and another R2D2 noise. I think I may also have seen lights flashing around the the edges of my blackout blinds, but am not sure, since I had just been sound asleep.
View 4 RepliesI have been getting a loud, high-pitched mechanical-sounding noise coming from the middle of the dash, near the CD player. It lasts only a few seconds, but it scares the sh!t out of me every time! It happens out of the blue after I've been driving for a few minutes about every 3 weeks or so. The sound is almost impossible to describe...but if you've had it happen you probably know exactly what I'm talking about. It happened today while I was listening to a CD, so I can't imagine it's the player that's doing it. Non-Nav/Air V8
View 1 RepliesI recently had to have e my alarm replaced on the car and after i left the dealer i parked and locked the car and came to notice that the chirp is no longer a chirp but a high pitched very loud beep that lasts longer than the previous chirp. The odd thing is that when i activate the alarm it sounds exactly as it should. I contact the dealer and asked if they gave me the right alarm and assured me that it is right and properly installed. What is going on??
View 6 RepliesEvery morning for the last 3 days I've gone to go warm up my car and each time i turn on the car only from a cold start up i hear this loud high pitch noise from the motor. If i turn the car off and restart it. It goes away and the car is at perfect idle. what is this and do i have some serious problems?
Is this true? If it's only on a cold start up, and then it goes away during normal driving, you have no need to fear....that's the Secondary Air Injection Pump that turns on during cold starts, and the plastic hose just needs to be replaced.. If so where is it located so i can replace this hose.
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 think my setup may be unique in that I have an XM commander, and Christian at Enfig made a special cable so that I have power connectors to the CD changer and my XM commander unit. Christian did a great job with this.
My dilemma is that there is a high pitched noise coming through the XM when the engine is running. It is not loud, and is not as audible at lower volume, but with my hearing problems, it is louder to me than to others.
The noise is not there when the car is not started. I guess there is no filter running the power to the changer (I am guessing), and now my XM commander box. I would not even know what to do regarding a filter or where it should go. The CD still plays clear with no noise. I have not connected an IPOD yet to the X3, but since the power to the CD and the XM commander is coming from the car battery, I figured that was the culprit.
Also, if I did not need the additional audio inputs, the XM roady I had in my center console via FM transmitter had more volume and more bass than my XM commander via X3. The XM roady did not sound good at all via the X3, and the XM commander was clearly better via X3 interface.
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]....................
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.

Started my R this afternoon and got a new high pitch noise that I have never heard before. [URL] .... What it is?
View 14 RepliesI have a high pitched noise coming from my car's navigation DVD. If I eject the DVD, the noise goes away. It starts up again when I put the DVD back in. Sometimes it doesn't make any noise, but it's typically on the whole time the car is on. When I stop the car, it continues for a little bit, which makes me think that it has something to do with the DVD rubbing against something.
A few months ago, I would get sporadic errors about the disc that would go away if I ejected and reinserted the disc. Other than the high pitched noise, it seems to be running fine now. The main question I have is whether replacing the disc has any hope to get rid of the noise or if I have a bigger problem and need to repair the system.
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?
