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.
View 13 Replieswhat could be causing this. The faster I go the higher the pitch sound. It only occurs when pressing the gas pedal. As soon as I let off the gas the noise is gone.
View 5 RepliesMy 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.
View 14 RepliesIt'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.
View 10 RepliesWhen 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).
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...
View 10 RepliesSometimes I will stop at a light and my idling rpm will go from 600 (usual rate she idles at) to about 950. While this may seem inconsequential in the grand scheme of things, it's noticeable enough that it seems like the car wants to go. It'll lead me to depress the brake more. You can also hear the higher pitch of the faster turning engine (it is a 50% increase in speed). This will happen at random times so I have not been able to pinpoint if it is caused by a particular driving style. ECM for this?
View 7 RepliesYesterday 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.
View 7 RepliesSo 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???
View 16 RepliesAccording to the manual the high pitch sound is to let driver know that the pads are worn out but i checked and my pad still very thick after 15k miles.?
View 13 RepliesI'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.
I have 1,600 miles on my elantra and this sound just started. On initial starting, when the engine is cold, there's this loud low pitch then high pitch sound. It only lasts for 1.5 seconds but it's loud. What could it be?
View 3 RepliesMy 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!!
The tone of my horn changes intermittenly from normal sound to high pitch. The high pitch sounds similar to a Japanese made 4 cylinder...for lack of a better description.
View 1 RepliesWhen 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?
View 10 RepliesMy 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.
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 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?

View 4 RepliesMy girlfriend has a 2001 Ford Escape 3L, 6cyl. When accelerating there is a loud high pitch whistle/whirling sound. The sound varies with the amount of throttle you give it. More throttle = louder whine. Doesn't seem to do it when idling or coasting. What that could be? I'm about to remove the belt and take a look at the drive belt tensioner and other pulleys.
Just checked pulleys and tensioner and the tensioner seems fine, a/c pulley spins smooth and free no play, alternator spins smooth no play. The belt needs to be replaced. I wouldn't think this would cause such a load whistle under acceleration. I would expect it to do it all the time if it was the belt. I'm looking at the water pump pulley and belt too and they seem ok as well.
It was a very nice week and rolled my windows down at Disney resorts. I noticed a very high pitch noise that the brakes did not seem to impact.
