Lexus RC F 2015+ :: High-Pitched Whine Below 1200 Rpm After Cold Start?


May 30, 2016

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.

Lexus RC F 2015+ :: High Pitched Whine From Rear End - Car Has Been Off For Hours

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).

Subaru - Outback :: 2005 - High Pitched Whine When Car Is Cold And Around 20 Mph

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?

Lexus LS 2007+ :: High Pitched Whine With New Rotors On 2008 LWB

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.

Lexus IS 2014+ :: High-pitched Whine When Driving With Pressure On Gas Pedal

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.

Lexus LS 2007+ :: High Pitched Electronic Whine On AM Radio Station

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.

Dodge - Durango :: 2005 - At Start Up Emit A High-pitched Whine?

I have a 2005 Dodge Durango, 5.2 liter hemi engine, 135,000 miles. For the last three months the car has emitted a high-pitched whine when the engine starts, while the transmission shifts through the gears, and while the car is at speed. The tone remains the same as the car runs, but it seems liked to the engine revs as the transmission shifts. A very reputable mechanic has tried to find the source without success. He's run all the diagnostics, and used a stethoscope. He checked the alternator and the power steering pump and replaced two belt pulleys, but the whine is still there. He so far has not been able to locate the source. He says he's heard the same noise on a couple of other Dodges or Jeeps with the same engine. I'd like to know what's causing this whine and how to fix it.

Lexus LS 2007+ :: 2008 LS600hL - Power Steering High Pitched Whine?

I'm beginning to notice a high pitched whine when I first start up my 2008 LS600hL and turn the wheel slightly (like backing out of my garage). It almost sounds like the beginning of a power steering pump problem, but I think our power steering systems on the LS are electric.

Experiencing a slight whine/growling sound when the car is still cold and the wheel is turned? Maybe the sound has been there all along and I'm just now noticing it.

I did a search on this topic and came up empty. My car is still covered under a CPO warranty, so I'm not too concerned, but was wanting to get opinions from the forum on possible causes (or if this sound is a normal part of the electric power steering we have).

Sonata NF (2006-10) :: High Idle Speed About 1200 RPM On Cold Start

Bought my 2006, V6, about 2 months ago. This morning was the first really cold once since I bought the care. When I started it today, the idle speed was about 1200 RPM. It took a few minutes to warm up and then the idle speed dropped to normal. Quick question. Is this normal?

Lexus RC F 2015+ :: High Pitched Gurgling Noise When Accelerating On The Road?

I bought my RC F new about a month ago and have put a very fun 1450 miles on it. Ever since I got it, there is this weird noise happening right at about 2.8k - 3k rpms. It doesn't seem to happen when I'm hammering on it as much as when I just accelerate on the road to get around somebody and peak at those rpms.

Not quite sure how to explain the noise, it's kind of a high pitched gurgling. Is this normal?

I tried recording it but you can't hear it through the video at all. If you turn the volume up and put your ear right next to the speaker you *might* be able to hear it. It's much more apparent in real life.

Prius (2010-12) :: High Pitched Sound - RPMs Go From 1200 Up To 3400 In 10 Seconds

I was driving today and had just gotten off the highway. I was going at no more than 10MPH when I heard some high pitched sound. At first I couldn't figure out what it was and thought maybe it was some outside noise. It quickly got louder over the span of the next few seconds and then I realized it was the engine. I had the pedal barely down so was definitely in electric mode.

I quickly glanced at my Scan Gauge and actually saw the RPMs go from 1200's up to 3400 in no more than 10 seconds. I have never had the car rev this high, probably just 2400s when I'm on the highway going 70's. By this time I was getting very perplexed and worried, and had my foot completely off the gas pedal. I immediately pulled to the side of the road and parked (hit the P button). The car seemed to go into park mode fine and then over the next few seconds the RPMs went back down to 992, and I made it back to the house no problem.

Golf IV R32 :: High Pitched Noise On Cold Start

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?

Golf/GTI VI :: Medium To High Pitched Whine

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?

Touareg :: Intermittent High Pitched Whine Above 10 - 15 MPH

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....

Golf VI R :: Strange High Pitched Whine And No Boost

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.

Prius (2004-09) :: High Pitched Whine When Accelerating

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.

Santa FE SM (2001-06) :: 2002 - Odd High Pitched Whine Noise

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.

Azera TG (2006-11) :: High Pitched Whine Sound When Turn The Car

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?

GMC - Sonoma :: 2001 - High Pitched Whine When Apply Brakes

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.
