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.
View 2 RepliesI'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.
View 3 RepliesHave a moderate pitch whine in front end only when steering or turning to right. Gets louder w higher speeds but pitch is about the same. Thought it was a left front wheeling bearing. Also needed new pads and rotor. While doing the job noticed grease all over the lower ball jt. Discovered a tear in the outer axle boot. Net net replaced pads, rotor, axle hub assembly and axle complete. To my chagrin the noise has changed one bit. The noise also doesn't change when I put the car in neutral while traveling downhill. With the hope that I replaced the wrong bearing I have ordered a new one for the right passenger side. When I tried the 6-12 wheel rocking test on the right there did not appear to be any looseness.

View 8 RepliesI 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 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.
View 4 RepliesWhen 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?
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?

View 5 RepliesI'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 a 2013 Prius. I was noticing a high pitch coming that I could hear when I had the driver side window down and the sound was reflecting against things I was driving by. It was strange because it didn't change pitch at different speeds, and it would be there most of the time regardless of whether I was speeding up or slowing down. And regardless of whether I was using the brakes or not. I've been told this is the sound of the inverter.
View 9 RepliesOver the weekend I discovered that the rarely used front passenger's window makes a consistent, continuous, low-pitch grunting noise while being raised up. You know like the motor is about to give up. It hasn't slowed down compared to the driver's window.
View 1 RepliesThe 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....

View 7 Replies2002 Passat wagon. I recently had my independent VW shop install new front and rear brake pads and rotors that I provided. The pads are PBR Axis Deluxe ceramic pads. Soon after, the front brakes started a high pitch squeal - mostly when cold or wet.
I took it back to the mechanic and he told me there is nothing he can do about it - I must have defective pads and that maybe they are covered under warranty, as they certainly need to be replaced, ...
This shocked me, especially the lack of customer service, but because I provided the pads I don't think I have much leverage with them other than not to do business with them again.
Is there any way to quiet a squeaking brake pad? Might the mechanic not done something he should have done to prevent squeaks?
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.
View 1 RepliesNew 2012 SE, I noticed a high pitch noise coming from the rear side of my car. The high pitched noise/whine happens as soon as the car is running, and continues until it is turned off. I can hear it every time when standing idle or at lower speed. So I brought it into the VW dealership, and my technician: "found noise described is the high pressure pump in the tank".
We tested another 2012 Passat SE and we found the exactly same(even louder) high pitched noise coming out from the high pressure pump. I was told by a service manager that it is a standard high pressure pump noise for 2012 Passat. Well I don't think that any high pitch ultra whine/noise should be a standard feature in any car...It is very,very annoying noise...
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.
So today pulling out of the gas station I turned my steering wheel to the left and I heard a high pitch squeal from the drivers side. It wouldn't do it again unless I was just creeping, nothing going down the road. I did a few searches on here but they all are if the truck is moving say 30 mph or better. I know I need to replace my ball joints. 99 F250, V10, 4X4, extended cab.
