Lexus GX 2004-09 :: Faint High Pitch Ringing From Idle To 2.5k RPMs Or So
Jul 30, 2015
I just changed my alternator because it was making a whining sound off/on, then just went completely dead. I got it back from the shop and that certainly fixed the problem. However, I now notice a very faint high pitch ringing from idle to 2.5k rpms or so, I hear it more so in the cabin. Also, if I hold at 1,500 rpms now the engine vibrates and stumbles right at that holding point, it didn't do that before. Is there a chance that this remanufactured alternator could be the problem?

My girlfriend has a 2008 with around 120k miles on it. It's been pretty flawless but yesterday the RPMs started surging while idle and made kind of a high pitch humming noise when accelerating.
Today on her way to work she said the radio was going in and out, the battery light lit up and then the rest of the dash lights came on, and the speedometer stopped working.
What could be the problem? Could it just be the battery?

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 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 just drove away in a new 2014 Dodge Grand Caravan - had 106 miles when I took title at the dealership - and immediately noticed the most annoying high pitched whine or whistle. It seems to occur under 2000 RPMs and starts around 25mph. It continues until about 45 mps and then either becomes less audible behind the engine noise or stops - hard to tell. When the car slows down, it comes back -- most of the time. It changes in pitch as the car goes faster and as it slows down.
It has been so loud at times that I think it's a police or ambulance siren and I have gotten ready to pull over. It does not happen in neutral when I rev the engine - the car has to be moving. Turning the wheels doesn't seem to make a difference. I am going to take it in to the dealer but I suspect they will just laugh and say that's how the car sounds. I've never had a car that had such an annoying soundtrack - and I've rented about 5 of these minivans over the past 3 years and never experienced this, either.

Starting about a week ago whenever my car goes above about 2 thousand rpms I start hearing a faint high pitched whining sound, increasing to a more audible level as the rpms increase.. I've ruled out breaks and tires, which weer my initial thoughts, and I think it's something with a belt or the engine now. I have manual shift 2002 Hyundai Elantra.. The car still performs fine, but I have noticed a slight decrease in acceleration speed..

Is this normal for the Camry? When you're flooring the car besides the typical roar I hear like a small high pitch noise, it's gone once I let go of the gas. I tested it & start to hear it at about 4000RPMs I believe. Recorded it on video but you can't hear it at all on video.

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...

Yesterday my truck started making a loud high pitch squeal at idle. Messing with it this morning I found when I turn the a/c on it quits. Then it will do it for a second at startup and quit. If the a/c system is turned off it comes back. I thought exhaust leak until I found the a/c link.

I've only had my RX330 for a week. Dealer set up our phone to work in the navigation screen. Everything worked fine until tonight. When we get an incoming call it no longer 'rings' through the car's audio system. How do I get the 'ring' back? The screen indicates an incoming call, but the ring has stopped.

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?

My 2013 GX makes this noise when I step on the gas padel when the speed is 70 mph or higher. It is not very loud but noticeable, even with the radio on. I noticed this these past two days on highway. There is no such sound during local drive or speed below 70. It sounds like it came from the engine compartment, but I am not 100% sure. Is this normal? Could it be from the wheels or chassis? My truck only got 1800 miles after 2 months driving.

Sitting in parking lot listening to ipod thru aux port opened door to access door pocket and sound system went nuts. I now have a high pitch noise coming through all speakers on all settings even with audio off.

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.

I have been driving my new ES 300h for a few days and have noticed that often when I apply the brakes, there is a faint high pitched noise in the cabin. It's not a brake noise of any sort, its clearly some electronic component. I was just wondering if this is a normal part of the regenerative braking system or not, as it is definitely quite audible and takes away from the otherwise very quiet ride of the vehicle.

It's been cold, but I've been driving. When I park and power down, I'm hearing a high-pitch sound...like a fàn...it lasts about 10 seconds.

I have a 2003 Toyota Prius, that you have to push sooo hard to make it stop, the ABS and brake light are on and there is some aweful chime that is solid and doesn't go away (very high pitch), I just got the car, and got it like this. I think its signs of a BRAKE BOOSTER, but I have been unable to loacted that, I found the Master Cylinder, but looks like you have to remove the Hybrid engine to do... Is there a procedure for this...

My Civic started to make high pitch noise when turning right or left, and also when accelerating. It makes more noise when I keep the wheels turning but ceases the noise when I let the handle go and go straight. When accelerating, it ceases the noise as it reaches 30 mph or so. It has got 93000 miles on it. It started the noise about 10 months ago and I feel like it increased the noise over the time. I don't drive everyday and I try to drive my wife's Prius when I drive since it has better gas milage. But this noise is quite annoying and wonder what it is.

My 2004 V8 Toureg has around 7K miles on it. The brakes are squeaking at a very high pitch. The same squeaky sound a bus makes when it stops. My dealership told me it is due to me not hitting my brakes hard enough. I have hit my brakes hard many times as of late and the squeaking continues loudly as folks will turn their heads. The dealership told me it is due to brake dust accumulation which if I wash the car they still squeak. Dealership also told me the VW regional field rep has told them that to rough up the brake pads which is a temporary fix. Dealership also stated if the brakes were replaced the brakes would start squeaking in a matter of a few months because this is how German cars behave. Not sure where to take this matter.
My other problems as of late are a bad power steering pump(replaced), bad suspension controller arms(new parts are ordered-kept hearing a popping sound when turning the tires and braking and grinding noise from the suspension), a bad keyless access module(replaced), steering column not centered(re-centered), wind noise from the rack ontop (basically to fix and probably only temporarily, unlocked them and then moved them forward a bit and then back to their original location- may have been loose as no more wind reverberation inside the car now), and rubbing from my driver side wiper. The brakes are the real thorn in my side at the moment due to other drivers hearing the noise while driving as they turn their heads. Very embarrassing especially coming from a new car!!

I have problem with my brake system. When is comes to last 10 feet to a stop light always make this squeaky noise/high pitch noise. Brought it to the dealer for few times and they said this is a high-performance brake that's why there is these type of sound. I have a 2014 IS350.

I've noticed a noise coming from my car (2014 IS350 RWD) that sounds like a light, irregular rattle, when the engine is running in the 3500 - 4500 RPM range. I don't hear it necessarily under load, but if I am in manual mode in a lower gear, and let off the throttle, I can hear it.
The best way I can describe the noise is like a bowl of rice crispies (rapid and random), only slightly louder. You have to listen for it, the road/traffic should be quiet, and if you get back on the gas, the intake noise that's plumbed into the cabin pretty much covers it up. I can also hear it in Park or Neutral.... I've wondered if it's a loose heat shield, or an exhaust issue, but I can't hear it standing next to the car or with my head under the hood. I only hear it from the cabin. The rhythm of the noise is irregular.
I don't think it's ping/detonation, since that usually shows up under load, is much louder and has a decidedly metallic sound to it compared to what I'm hearing.
