Prius C :: 2013 - High Pitch Sound At 62 Mph And Higher

I have a 2013 Prius c #2. At 62 mph and faster there is a high pitch sound that gets louder the faster it goes. I have asked two other Prius c owner's and they don't hear it. You will need to roll up the windows and turn the radio off to hear this.

Lexus - Es300 :: Low Pitch Growling In Reverse / High Pitch Screech When Apply Brakes

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.

Santa Fe (DM - 2013+) :: Ventilation Fan High Pitch Noise / Squeal

Yesterday I heard a high-pitch noise/squeal coming from the vehicle and after some searching, figured out it was from the ventilation fan. It went away after 5 mins of being on but is rather annoying. Not too keen to take it in as I'm sure the dashboard will need to be removed and afraid it won't go back in perfectly.

Lexus ES 2013+ :: ES300h - High Pitched Whining Sound When Going At 40 - 50 Mph

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.

Lexus GS 2013+ :: High Pitched Whistling Sound When Coasting At 60 Mph

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.

Passat (B6) :: High Pitch Sound - Possible Boost Leak

So i have a '06 2.0t 6spdman passat. I started getting this high pitch sound (like a boost leak) when under hard acceleration from second gear and up. I went to the dealer today and they replaced my PCV system, and told me that was the noise i was hearing. Pulled out of the dealer like half a block and same thing happened. Then the tech went with me heard the noise, went back put it on a lift. And proceeded to just rev the engine. They say its my Intake system, yet I have had it on the car for 2 and a half years. Could it possibly be the DV???

Elantra GD (2013+) :: Clunking Noise Coming From Steering Area / High Pitch Squeak When Fan Turned On

I've been noticing some new noises in my Elantra in the last couple of months.

First, there's a clunking noise that sounds like it's coming from the steering area. It usually happens when I back up and rotate the steering wheel, like when I back out of my parking spot. More often it's in the morning.

Second, when I turn the fan on there is a high pitched squeal. If you turn the fan off you can hear the squeal more clearly for a moment as the fans die down. This one only started happening in the last couple of weeks.

I guess I'll have to take it in and get them to take a look. Last year it was a squeaking in the pano roof which only happened when it was hot out. They seemed to have lessened it but it wasn't gone completely.

Prius Plug-in 2012-15 :: High Frequency Pitch Sound

When I test drive the PIP, I kept hearing a high frequency pitch noise whenever the car was accelerating. It almost sounds like when you lightly touch the trigger on a cordless drill. Sales guy and my wife couldn't hear it, but I do have extremely sensitive hearing.

A quick search didn't reveal anything, so I am wondering if this is a problem, or maybe part of the pedestrian warning system (although it happens at higher speeds as well).

Touareg :: 2004 - Brakes Squeaking / High Pitch Sound?

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!!

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?

Golf/GTI VI :: 2012 - High Pitch Continuous Whistling Sound From The Engine

My first VW was a 2001 4-door Golf (Silver), traded to 2003 GTI (Silverstone), traded to 2006 Jetta Wagon (Blue). Then the wagon was traded for a SUV. Well last week, I have decided to pick up my 4th VW. It's a 2012 CSG 4-door GTI.

After driving the car for a week, and putting on 350 miles, I heard a high pitch continous "whistling" sound from the engine. Took the car to the dealer this afternoon. Tech came out and loosened the coolant reservoir. I heard a "pooof", sound of air build up. The tech said VW is aware of this problem. Something to do with the water pump bearing. It has to be replaced. They took the car in to replace the water pump.

Golf/GTI VI :: 2010 - Faint High Pitched Whirling Noise While Cruising

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?

Ford Super Duty (1999-2016) :: 2011 - Whining And High Pitch Squeal Sound?

I have a 2011 F-350 Diesel. It started making a strange whining sound when I start it in the morning. Very random and only does it when it's 0- -4 c. Took it to the dealership and they said its the cooler fan clutch. Got it replaced yesterday, and this morning I started it up and the whining sound was back. It also had a weird vibrating sound. What it could be?
