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.
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.

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.
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.
View 3 RepliesI will try to film the sound and post it later; but for now I have a 3.5L V6 AWD with 85k on it. i get grunting and groaning on colder mornings and sometimes a med pitched whine, more noticeable at higher speeds in town.
View 9 RepliesI have the Bridgestone Turanza EL400 radials on my car and now at 8000 miles I have started hearing a noise that is hard to describe. It sounds like a singing, or medium to high pitched whine (no, it's not the transmission sound others have reported). It occurs anytime I'm above 20 MPH. I can put the car in neutral at 55 and coast and it's still there, so it's not the engine (which is idling while I'm coasting). I can't detect any noise from the engine at all at idle or at speed. I took a dealership technician on a ride and he thinks it sounds like tire noise. I have heard some complaints on one of the tire sites about this brand being noisy after a few thousand miles.
View 9 RepliesI'm having an issue with my 2001 F350 V10. A seriously annoying high pitched whining noise appeared a while ago, then disappeared, and has now come back.
It happens as soon as I start my truck, whether it's cold or warmed up already. it increases in pitch and loudness as I increase RPM, it also does exactly the same in neutral. As soon as I put it in gear (R, D, 2, 1) it completely disappears and will come back as soon as I shift back to P or N. Strangely, if I drive around town for a few minutes, when I get back home and shift to park the sound doesn't really come back, sometimes it will be faint but usually it's totally gone. But if I shut the truck off and turn it right back on again then it's there again.
It's coming from somewhere in the engine compartment or close but due to the nature of the sound it's very difficult to locate. I got underneath using a screwdriver as a stethoscope and listened to the transmission, transfer case, starter, oil pan and even the gastank and it doesn't sound like it's coming directly from any of them. While underneath I noticed power steering fluid leaking from the pump behind the pulley and dripping off the hose. Somehow though I don't think it's related as the sound disappears in gear and doesn't change at all when turning the wheels. I cleaned the fluid off and drove around a bit and it doesn't seem to be leaking too badly and my reservoir is totally full.
The truck otherwise is driving as good as it always has and whatever this sound is doesn't seem to be having any effect on performance (yet...) ...
There's a high pitched whine type noise coming from my Mass Airflow Sensor. I can get it to go away temporarily if I goose the gas pedal, but it comes back after a minute or two. Has not affected drive-ability, but it's pretty annoying. It sounds like the hot wire is probably vibrating. Is there any fix for it, or do I have to replace the sensor to get rid of it?? Have tried cleaning it, but that did not work.
View 6 RepliesI 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.
Had my first drive with the windows down for a long time and noticed a new medium to high pitched whine, stays relative to engine speed. Not the turbo, its much louder than that, i searched about the water pump issues and no one seemed to mention any associated noise, just coolant on the driveway. Waterpump? Alternator?
View 5 RepliesThe vehicle is a 2005 Touareg 4.2 v8 with 81k miles. I purchased from a dealership and have been having nothing but problems from the day I purchased it. (2 months ago) the day after I purchased it check engine light came on, headlight range light, air bag light, and now this noise I have owned about 15 vag cars and also own vagcom no codes pertaining to this noise... Above 10-15mph there is an intermittent whine (high pitched) for the most part the noise is there most of the time.
It does not stop when in neutral not effected when the air is off or on, does not change if you down shift, no change if the wheels are turned. I broke down and took it to a very trustworthy Audi shop in the area and you guessed it the entire way there no noise... The tech drove it no noise so I had them flush and fill the trans as it was due for it anyways. They informed me that it was dirty and I figured that it may have taken care of it. Well after a 20 minute drive home the noise started again! I took a short video....
I recently noticed that my Golf R was making a strange high pitched whine and it seemed like there was no boost. I took my car to the dealer, and it turns out that part of the CAI broke off (a mounting component) and made its way into the turbo, effectively destroying it.
My dealer was initially intending to cover the turbo under warranty (prior to investigation), but now that it is clear that a failure in the CAI caused the issue, they cannot (obviously) cover it under VW warranty. Unitronic CAI failure led to turbo failure.
The serviced manager did some research prior to getting back with me, and was somewhat puzzled since the Unitronic CAI displayed on their website looked slightly different from mine in that the component that failed was not there. The service manager called Unitronic and learned that the failed component was a known issue (it had apparently failed before), and thus they modified the design - hence the picture of the revised version did not match the older version that was installed on my Golf R. The Unitronic rep offered to replace the CAI - but did not mention anything about the failed turbo (when he spoke to the service manager).
I found the following thread which illustrates that this was a known issue: [URL] .... I just wish I had found out about this before it failed.
My car has 155k miles and I haven't had any previous issues with it. I noticed probably 30k miles ago the beginning of a whine sound when the car accelerates. The noise has been getting louder (it's really not that loud) but I am wondering what this could be. I want to avoid anything happening to the car and want to find out what the problem is so I can fix it.
View 6 RepliesMy 2009 Camry with 72k on it has started to make an intermittent high pitched whine from the rear of the car. It's only noticeable while accelerating or maintaining speed.
View 1 RepliesJust 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.
View 2 RepliesCar was in the garage. Had been off for hours. Husband noticed a high pitched whine coming from the rear of the car. Louder underneath. I opened the trunk and took out everything in the cargo net (thought something had gotten stuck in it, a gadget of some kind). Nothing there. I went to unhook the net and pull up the mat etc. and the noise stopped (coincidence I'm sure). I couldn't find anything. It didn't sound like it was coming from the wing at all (had trouble with wing being stuck down when I first got it).
View 13 RepliesI noticed when I first start of my 2006 Azera at night or even during the day and make the first turn of of my driveway or out of the parking lot at work there is a high pitched whining sound. Sounds like it maybe coming from under the car maybe from the back. I thought at first it maybe a belt (power steering) under the hood but it sounds like it coming from the back side of the car. It only does it one time mostly when its cold outside. What can it be?
View 8 RepliesAbout 2 months ago, I noticed a high pitched whine on my 2005 Subaru Outback. It honestly sounds like a siren and is very noticeable. It occurs more often when the car is cold (1st thing in the morning) and around 20 mph. It sounds like it is coming from the rear of my car. It occurs whether or not I am pressing on the gas pedal. Once I get above about 30-40 mph, I don't notice it anymore (don't know if this is because other engine noises are drowning it out or what). It does not change or get worse when I turn. It seems to subside once my car is warm. Other people have heard it and some describe it like an airplane taking off.
I took it to the Subaru dealership and they said it was my alternator. Lo and behold a few hundred dollars later, it was still making the noise. A few days later, my CAM sensor went bad and I was back in the shop. Of course, I tried to get my car to make the noise for the mechanic, but it wouldn't cooperate. They didn't see anything wrong, but it is still making the noise. I have taken it to the dealership and they couldn't get it to make the noise. My rear wheel bearings were going bad and so I replaced those - under warranty, but it still makes the noise. I keep up with all my oil changes, services, etc. I just had the fluids checked and the power steering fluid is normal. The power steering pump has also been checked and it is normal. What this might be?
I have about 1000 miles on my 350 F Sport AWD, whining noise. When I am driving with any pressure on the gas epedal, I hear a high-pitched whine in the cabin. If I take pressure off the gas pedal, the sound stops. It comes back as soon as I touch the gas pedal. The sound seems to be coming from the rear of the car, and it happens whether the audio is on or off.
View 5 RepliesI 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.
View 10 RepliesI posted a related video in the fuel pump thread here where the high whine noise is apparent several seconds after a cold start. Now from inside the cabin, looking at the revs, the "sewing-machine-like" whine disappears above 1200 rpm.
