Honda - Accord - Noises :: Inconsistent High Pitched RPM Related Whine
Aug 1, 2013
I have a 99 Accord, automatic trans with over 197,000 miles, appropriately maintained.
What is the most likely cause of a very high pitched whine that comes up when throttle is being added? Here are some facts: -This is not a constant, or even a daily occurrence. Very randomized. I think I first noticed it over a year and a half ago (20,000 miles).-The sound will continue if the transmission is put in neutral and the RPM maintained (usually 2,000 - 2,500).-If the A/C is on when the sound happens, it will go away when I turn the A/C off.-When the sound is happening, there are no adverse symptoms to go with it. The car runs and drives quite well. Well, this issue is just that inconsistent.

I just had my 2003 Honda Accord Ex in the shop. I was without my car for a week. I broke down on the highway and had to have it towed, not once but twice. I took it to a reputable Honda/Acura repair shop. It turns out the ECU was corroded and the A/C drain was plugged up. I was not aware of the design of the Honda in this area, however, with the A/C unit being above the ECU in makes it easy to destroy the ECU if there is any problem with the A/C. Seems to me that Honda might have wanted to recall this to put plastic between the 2 to prevent the corrosion of the ECU or something, however, no such luck. The mechanic pointed out that the carpet on the passenger side was damp and to check it. Who would a thunk?
I got the car back yesterday. After running the diagnostic equipment they had to replace the ECU and ignition responders, put plastic between it and the A/C unit, replace the spark plugs (apparently the wrong ones were installed), and #4 coil, have the keys reprogrammed, replace the A/C filter and clean the A/C drain. Now here is the rub..I got it back and drove down the block. There was a high pitched whine or whistle sound that occurred when I accelerated. And the same sound when I took my foot off the petal as it was slowing down.
I immediately drove back to the shop and the mechanic and I took a drive. He had heard it also before I got it back. He mentioned it might be the transmission and that if it needs replacing. The car has 170,000 miles on it and it the past 2 months I have had new tires. He suggested I drive it over the long weekend (Labor Day) then make an appt to bring it in next week to have the transmission checked. So here is my concern, if it is the transmission will I do more damage by driving it? Will it get worse quickly and break down thereby leaving me stranded again? What is the best thing to do?

My car started whining a couple of months ago. It is intermittent, at slow speeds or totally stopped. It's a high-pitched whine that sounds like a small dog yelp. I can't make it happen and can't discern a pattern as to when it happens except that if it occurs once one day, I'm likely to hear it a few more times that day. It sounds like it is coming from the right hand side, perhaps from underneath the car. I've taken it in to the dealer who checked it over. Of course it didn't make the noise for the mechanic. The dealership said they have heard this complaint one other time by an owner of a high mileage CRV. They are not able to determine the cause. My car is 2002 and has 172,000+ miles.

Parked my Honda Civic (1997 stick shift) in driveway at a slight forward downward slant. Two days later it wouldn't start: dash lights come on, get high pitched noises from engine but no start. Tried for 2 days, same results. Ambient temp is in 60's. Had routine service 2 weeks ago and it was running fine.
Tow truck driver tried it, got same results. Had it towed a mile to mechanic (front end elevated while towing). Mechanic called to say it started on first try for him but seemed to be running rough. He checked it over and now has come up with 2 or 3 things it may be but isn't really sure.
Mechanic Is going to replace the ECP (?) to start with but is going to be going at it one part at a time.

I recently had an oil change at a new shop. While I was there, they said I needed to get a power steering and brake fluid flush and recommended a fuel induction service. I have a 2003 Honda Accord with about 107,000 miles on it. The car runs fine, I have no problems. Occasionally, when I hit the brakes, there is a high pitched squeak.
I've been doing research and getting mixed results on if these services are necessary. What could be the cause of the brake noise?

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?

The 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.

My 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.

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.

Car 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).

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.

I 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?

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.

About 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.

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 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.

I'm going to take my 2012 Camry SE in for service sometime in November and experienced a high-pitched whine (very low volume) in the front end of their car. This sound seems to be coming from the front passenger side of the car and has surfaced only within the last month or so, between 70-75 MPH. Above and below that speed range I hear nothing. This car has low mileage; after almost two years, it has only about 12,500 miles on it.
I'm wondering whether it's a trans-axle whine, but it is of such low volume I don't think it would be easy for a tech to diagnose. Also, other than the D1T recall, are there any other TSBs that I should be aware of, and any recent Entune updates that need to be applied? And, whether Toyota has a remedy for D1T yet?

I 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.
