Lexus ES 2007-12 :: High Pitch Jet Turbine Like Whine When Driving At 75 Mph
Nov 30, 2014
I just bought a 2007 es350 yesterday with 67k miles. When I test drove the car, the highway was too congested to get the car above 50 mph. So, the car sounded fine to me and I purchased it with a free 90 day, 3k mile powertrain/engine/transmission warranty. The car should still be under its standard 7 year 70k mile warranty as well, right?
Fast forward to today. The highway was less congested and I was able to get the car up to 80 mph. However, I noticed a constant hum start at 60 mph, which became louder and more high pitch at 75 mph. I am taking this back to the Lexus dealership from where I purchased it to get the sound diagnosed and repaired. I'm hoping it's a problem still covered by the warranty, like the differential (does the ES350 have a differential since it's fwd) or pinion bearings. Could it be something simple, like a bad tire?

I went to go start my LS460... put the heat on, its fine.. when I turn the heat up on high I get this annoying high pitched sound. It has to do with the heat system because when I turn it off it goes away... I'm scared to keep the car running...

I've got a 2006 Prius - yesterday afternoon my wife and I noticed a high pitched whine coming from the front (maybe right hand side) of the car - we don't hear it until we reach about 50mph. It gets louder as we increase speed and then trails off when you step off the accelerator and can't hear it all below 48-45mph.
We bought the car new and are familiar with the various noises the car makes, but this one is new - never heard it before yesterday.

During around town driving I am experiencing a faint high pitch whine when braking. This sound is not mechanical, but more electrical coming from the dash-engine area. It is very noticeable when slowing between 40 mph to 20mph.

I have 2002 Chevy suburban. Recently, a high pitch whine has developed. When accelerating the whine intensifies. I replaced the alternator ... No change! What could it be? Speedometer cable?

I had a rebuilt alternator installed on Thursday and for the past two days when I start up the car there is a high pitch whine coming from what I believe is the alternator. Do some rebuilt alternators make noise when charging the batter after start-up? The alternator has a 3-year warranty and I'm going back to the shop tomorrow.

When I'm driving at a certain speed (usually between 65-70 mph), my 06 Sonata GLS V6 develops a really soft (but really annoying) high-pitched whine that decreases when you take your foot off the gas. Not much at other speeds (sometimes it will kick in real quick at high rpm before the automatic trans shifts), but when the car hits 66-67 mph that little subtle whine kicks in. By 75 mph, it's gone (I drive 75+). Sounds just like a high-pitched dog whistle.
Not a wind noise....sometimes it sounds like it comes from below me, sometimes it sounds like it's coming from the dash. Dealer don't hear anything (of course), even when I'm in the car with the tech and can hear it (maybe I'm part dog.....who knows).
Here's my guess.......I think that it's the electric fuel pump. Sometimes if I'm outside the car, I'll hear a whine back in the fuel area that is almost the same pitch as the whine I hear at 70. Since the whine varies (or disappears) with engine rpm and application of the gas pedal, my thought is that I'm hearing the fuel pump hit a certain pitch, which causes the whine.
2006 Sonata?

I've got a 2006 Prius - bought new in 2006. Yesterday I started to hear a high pitched whine or hum from what sounds like the front right side of the car. I hear it when the car reaches about 48-50 mph and seems to increase as you go faster. Once I let off the accelerator the sound slowly goes away. I know there are a lot of noises from the Prius, but this is one I've not heard before.

Our 2008 Honda CR-V w/120k one owner, always dealer maintained, vehicle has recently started exhibiting a little high pitch whine coming from the engine area which increases when you rev the gas. I checked the transmission dipstick and the level is just below the bottom hole (owners manual says it should be between the bottom and top hole). Would this make the whine? By adding some fluid should it go away? Is it okay to use a fluid other than Honda's?

I have a 1995 Lexus ES300 with 130,000 miles on it. When I reverse, I get a low-pitch growling and as as soon as I apply the brakes by a high-pitch, ungodly screech. This noise is definitely coming from the rear wheel areas. I'm not sure which tire is the culprit (I hear both sides from while listening from both the inside and outside). It happens frequently but is particularly bad on rainy, snowy, misty, or high humidity days. Two years ago I replaced the pads and rotors. At this point, the pads look to have about 40% life on them yet. This problem started happening about a year ago.
My initial thoughts were that it was just rusting because of the frequency on high moisture days. But both noises are way too loud for that. My second speculation was that the emergency brake was catching, but after examining it I think not. I've taken the entire assembly (brakes, rotors calipers, and emergency brake) at each tire apart and looked for any obvious issues that look incorrect. No luck. I've also applied brake quiet with similar results. Now my thoughts are that the low pitch is the rotors being warped. But that doesn't explain the screech and why it only occurs in reverse.

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.

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.

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.

We've got a 2011 Santa Fe V6 that's putting out a low pitch cyclical whine at speeds between 5 and 15 mph. It could be making the sound at higher speeds but if it is the engine/wind noise drown it out.
If you're coasting or braking and drop below 5-7 mph, the noise cuts out completely and abruptly. Makes noise regardless of A/C running or off. Sounds like a motor turning on and off. Never makes noise while parked and revved, only while moving at low speeds (stop and go traffic, driving through parking lots, etc) - and is just loud enough to drive us crazy wondering what it is!
Dealer service center checked it out for 3 days - 4 different techs drove it, all heard the noise, but none knew where it was coming from. When you're driving, it seems to be coming from the passenger side of the engine.
On a side note, we first started hearing this noise after we got it back from dealer service, where they replaced the TPS and A/C compressor. I'm wondering if it could be from something they had to move to access the compressor?

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).

When driving in 3rd gear I can hear this quiet yet distinct high pitch whistling sound. It almost sounds kind of digital. You can hear it inthe other gears but just not as well and I know it's not the turbo or anything. What it may be and if it's normal?

The car required a new water pump, the mechanic suggested to also replace the serpentine belt because of age - after a week the car made high pitch noise when started, the noise stopped after the initial start-at the shop it was explained that a new serpentine belt requires tightening after the car has been driven for a while - like a week- is this correct or was the belt not installed correctly....

I purchased a new 2011/2012 Santa Fe (R2.2 VGTi Auto 7 Seater GLS AWD) recently and noticed a high pitch noise on the audio system. This high frequency disturbance is audible with the engine off (eliminating the alternator as being the source). This is also present with the volume set to a minimum.
