Lexus ES 2013+ :: Faint High Pitched Noise In The Cabin When Apply Brakes
Jan 4, 2013
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.

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.

I have had my certified 2010 Prius II, not two because it is a 2010 and 2010 used uppercase roman numerals for model designation, with 82000 miles about 3 months and sometimes when I apply the brakes I hear a high pitched whirring noise. I think the closest thing to compare it to would be a skill saw but not that loud.

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.

I drive a 2010 Golf Wagon/JSW, and when I'm going at speeds around +60 mph/90 kmph and lift off the accelerator a faint high pitched whirling noise comes on. As soon as I tap the gas pedal it goes away. What this could be?
It's been a week now since I've noticed this, I guess I've never noticed it before or it's getting louder..i don't know?

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..

So I'm driving home late at night, few cars on the highway, I turn off the radio and I hear a faint, very high pitched whine coming from the engine bay when going 40-50 mph. It sounds like an electric motor spinning at high speed and frankly it's a bit irritating. The sound is there whether the engine is running and charging the battery, the car is using the traction battery or it's coasting and regenerating power. The sound stops for a moment if I gently accelerate and then lift off, but it comes back on coasting.
It's different from the louder, low pitched subway-train sound that comes from regen braking at low speed. Could this be the dreaded CVT whine reviewers complain about? Or is it the normal sound of the MG1 unit? This car is really quiet so weird noises pop up more.

I finally got a recording of this, after trying to describe it without much success. Dealer drove the car 2x and claimed they don't hear it.
Video here, turn up your sound... noise happens just as the gas is let off...
As you can hear (if you turn speakers up, recording isn't very sensitive), it's kind of a high pitched whistling sound or whining sound. Happens when coasting (foot off gas) at 60mph. In gear or neutral, same noise. Only around that speed, only when foot off the gas.
What do you think this is? Some have suggested wheel bearing but if you listen this is more of a steady high pitched noise, not a helicopter like sound.

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.

When I apply the brakes on and off while in park, I hear a "fluttering squeaking" noise. I examined the brake pads and calipers, and everything seems to be fine. I greased up all the brake hardware and no luck.
Also, I have a popping noise while making turns while I am not braking. I really doubt there is any connection with the brakes? I recently went testing in a parking lot, and while slightly turning from left to right I noticed the popping constantly. Keep in mind no brakes were applied.
Last year the dealer replaced the brake actuator and all arms were replaced. BTW, I am past my extended 100K warranty!!

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?

With only 1,800 miles on my 2016 Sonata Limited, the brakes make a high-pitched noise when applied and backing up. I noticed yesterday the noise has also started as I brake for red lights.

Hear a high pitched whistle inside the cabin while driving above 60 mph? I can even hear it over the radio most of the time, with the windows up! I have found it to be the mirrors! After hearing this noise, and pinpointing when it occurs, we finally found it is the mirrors. When they are folded in at speed, the noise disappears completely. I had it to the dealer, who couldn't pinpoint it, and I was trying to blame it on the tires, but found this instead.

When I accelerate A/C is fine but when I go to brake (RPMs go down and car downshifts) my A/C blower power goes from high to low and then fixes itself and if I brake again same thing but it does it intermittently. What it could be?

The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?

I have a 2007 Sante Fe Limited that has 93k on it. Within the last year I have noticed the steering wheel will shimmy when you apply the brakes at high speeds, it's slowly came to the point now that anything above 40mph will cause the steering wheel to shake while applying the brakes. I am guessing I have warped or unevenly worn front rotors. The car supposedly had a break job done at 74k and this started happening at about the 90k mark.
I was looking at these : Front Performance Brake Rotors Posi Quiet Ceramic Pads for Santa FE 07 09
Second question, any tool list or required sockets sizes to complete a front rotor and pad replacement? I have a floor jack, jack stands, a set of 3/8 deep metric sockets. I also have a breaker bar. This is my only car so I want to make sure I have everything I need before I start taking stuff apart.

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.

I purchased a 2014 LWB six weeks ago. The vehicle runs great. For the last three weeks, I hear an unusual high-pitched sound when starting the engine for the first time that day (temperature between 40-60F). See videos below. Ride height is set to normal, so I don't think it is the air compressor. You may notice that the whine goes away when the idle rpm falls from 1500 on the first start.
First start (8PM), driver window open, high-pitched motor whine [URL] .....
Second start (8:05), window open, normal engine noise [URL] .....
Third start (8:10), window closed, normal noise [URL] ....

We own a 2013 RX 350, purchased less than a year ago. We are experiencing this rattling noise coming from inside the side panels, its frequency changes depending on road and weather conditions like if road is rough or if its windy. We have taken the vehicle to Lexus Service three times so far for the same issue, they have acknowledged the issue. Last service took almost a month but still no remedy.
As of last service, Lexus took the entire roof liner down to fix the issue but it came back after one day post service.
Noise is extremely irritating because it occurs next to driver's left ear and is annoying as anything can be. Same goes for right ear for the front passenger.
We have owned Nissan Maxima, BMW and Lexus before and none of the vehicles had this issue.

I have a 1999 Ford Taurus. I have noticed a faint knocking sound for about 6 months. I took it in and the mechanic said ' what noise? '. Then it got louder so I took ot back in and he ssid 'bad water pump' I had another mechanic friend check, and he said the water pump was fine. Plus, I've never had any overheating . a 3rd mechanic said "could be loose torque converter bolts." It sounds like metal clunking on metal under the hood.. rpms, speed, & temperature make no difference. Occasionally get a smell of coolant inside the cabin . I'll attach audio of the noise.

I recently purchased a used 2009 Kia Rio. I really am enjoying the car. While there is nothing fancy to it, it gets me to and from work and that's basically what I need. However, when I apply the brakes, there is a high-pitched squeal that is made until the car is almost at a stop. It does this I would say 90% of the time. The brakes work just fine and are in fact very sensitive. I've tried researching this online and it seems a lot of people have this problem because of the type of brake pad used. The dealership I purchased it from is more than an hour away from my home, so I am reluctant to drive down there if there really is nothing that will be done.
