Camry :: High Pitched Whining Noise Coming From The Engine Bay
Turned my car (07 SE v7 with 240k on the clock) on this AM and there was a high pitched whine coming right from the engine bay - matched to the revs of the car, regardless of gear.
This is a new noise to me and the car - but I'm assuming it's some kind of belt issue.
Camry :: 2010 LE - High Pitched Whining Noise When Accelerating Or Revving Engine In Park
I bought a CPO 2010 Camry LE (2.5 4 cyl, 6 sp auto) a few months ago. The car had around 34K miles when I got it, and ever since then, it has had a high pitched whining noise when accelerating or revving the engine in park. It is noticeable from around 2500RPM up, and seems to be a little louder when the engine is cold.
I have left it at the dealer twice, and both times they have come back and said it is normal. I can't believe this, because I have owned many cars over the years, most of them being fairly dilapidated, yet most of them haven't had a noise like this. I think I have read a comment online somewhere that an issue like this was found due to a bad power steering pump .
Prius (2004-09) :: High Pitched Whining Noise After Turn Off And Restart
I know this noise is the Thermos Pump and it operates when I turn the car on and off. Question - is it failing - also a really annoying noise, but I'll put up with it as long as nothing's breaking.

I got in my car today and realized it was making a whining noise, kinda like the whine of a super charger, I don't hear it at idle but when I accelerate or rev it in neutral it gets louder and higher pitched. Friend had this problem in his Mercedes and he said it was a bad belt.
View 3 RepliesPrius C :: High Pitched Whining Noise When Braking?
I've noticed more and more that when I am braking that I heard a high pitched whining noise. Sort of this ultrasonic type sound. It will only go away if I depress the brake pedal very firmly after being completely stopped. However every so often the firm press will not stop the noise. I hear it more in the evening on the way home than in the morning to work, though I may not be paying attention as much in the A.M. due to morning brain fog.
I don't hear it any other time. I'm worried something is wrong with my inverter.
Subaru - Legacy :: High Pitched Whining Noise For Engine

After it has been sitting overnight, I hear a somewhat high pitched whine while driving the car. It seems to go away after the car warms up a bit (maybe I can't hear it). Here are a few other details
a. 2006 Sonata 3.3 V6, ~85K miles on the odo
b. Transmission fluid flushed at Valvoline ~2 weeks ago. I changed it at 39K miles when I bought it. Checked at 78k miles and the color was was good (light red).
c. The noise goes up and down with engine rpm. I have a sound (wav) recording of it, but cannot figure how to attach it.
d. I tried putting it in park and neutral and revving the cold engine, but cannot hear the whine-only happens in drive.
e. Engine oil changed every 3-5k (wife drives it, so I'm not always prompt).
It shifts smoothly (always has) and otherwise drives well.
Hyundai - Elantra :: Faint High Pitched Whining Noise At About 2000 RPMs
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..
View 4 RepliesToyota - Yaris :: 2009 - High Pitched Whining Noise Getting Louder With Accelerator
I have a 2009 Toyota Yaris with 35,000 miles, and fully up-to-date with all the 5,000-mile usual maintenance checks [no prior problems]. Driving on a hot day, I hit Bakersfield and the car started to make a high-pitched whining noise, which got louder with the accelerator and softer when I took my foot off the gas. I thought perhaps the car was overheating and let it rest for a while, and checked the coolant [which was at a normal level]. I finished the drive to LA and stopped by the Toyota dealer who said it must have just been the fan given the hot weather.
The noise went away overnight, but the next day I was driving around town when it was overcast and cool, and even driving locally, the car made the whining noise intermittently, especially loud at low speeds like coasting in a parking lot, and the noise has been getting louder and sounding more pathological--not like a normal engine or fan noise, but like a truly problematic high-pitched straining sound. Sometimes it comes on when I start the car, sometimes restarting the car makes the noise go away for an hour or two.
It sounds almost like an electric razor being whipped around like a numchuck - a hitch pitched whine that is rotating in the engine and speeds up with the accelerator and calms down but doesn't go away at a stoplight. Perhaps I finally ran over my neighbor's annoying kitty. But today's latest Toyota mechanic also couldn't figure it out because the noise didn't start when he turned on the car and didn't restart on his test drive, but only a few hours later after I'd driven the car around town.
Civic - Honda :: 2002 - Whining / High Pitched Humming Type Noise When Driving Straight
I have a 2002 Honda Civic EX with 146,000 miles. It started making a whining/high pitched humming type noise whenever I turned. Every now and then it makes the same noise (though not as loud) when I'm just driving straight.
When I checked my power steering fluid, it was low, so I added to it. That worked with the noise briefly, but now it's back and the fluid level is fine.
Ford Super Duty (1999-2016) :: Truck Makes A High Pitched Whining Noise
I noticed my truck makes a high pitched whining noise. It does it at idle and while acceleration up to 40 mph or so. The pitch of the wine increases with RPM'S. It is not the cold start whine issue I have researched on YouTube.
It is in the cold or warmth. No difference. It's always there. My 2012 6.2 did not sound like this at all. I have crawled under the truck and it appears like it is coming from the transmission.
Lexus GX 2004-09 :: 2006 - Battery Light Came On - Whining Noise?
So about 3 or so weeks ago I brought my 2006 GX470 into the Lexus stealership and had the pulley's, water pump, and timing belt replaced. Fast forward to this morning, about 300 miles driven and it suddenly when started today has a terrible whining sound and the battery light is on the dash.
I need to go over the invoice from what they did but I believe it was 4 different pulley's they wanted to replace. Not sure if it was anything on the accessory belt path, but I imagine if I call they will blame the alternator and tell me to shell out hundreds more?
I didn't run it long like that, only a minute or so. Popped the hood and I could smell the burning rubber smell so I quickly shut it off. Nothing *appeared* seized to me however.
Ford F-150 (2004-2008) :: Battery Light On And Whining Noise From Pulleys
I have 2005 F150 XLT 5.4 litre engine and my battery light comes on after letting the truck run on idle or sometimes driving.
Last Saturday went out drove it heater on and radio on I smelled something coming from the heater kinda like burning wire smell didn't think anything of it no smoke from heater (indicating the core was bad) no lights on the cluster nothing; went into the bank let it run came back out my battery light on. Drove it home and while driving the light goes off.
Opened the hood and the smell was coming from the alternator. So I turned the truck off. Let it sit for an hour or so then I took my voltmeter to see if the battery was good. The battery was 12.4v with engine off. Checked my battery connection for corrosion or loose connections everything was tight there was some dust on the battery terminals so I brushed them off. I checked the battery cable that goes from positive to the alternator where it connects to the alternator with that nut it was good, clean and tight.
So I started the engine up and I can hear a whining noise from one of the pulleys. Let it idle for 2 minutes no battery light so I put my voltmeter on the battery it read 13.8v, so I turned on the A/C, head lights, radio and the heater tried again the voltage dropped down to 11.9v then the battery light came back on. Also through all this my battery gauge in the cluster always stays a half way mark doesn't drop or go high. Next with the engine turned off I took the belt off checked the pulleys the idler pulleys seem fine and the belt doesn't show any glazing but the alternator was hot almost like touching a hot exhaust manifold.
So for the last 3 days I have been trying to come up with how to resolve this issue obviously it could be the alternator going bad but the battery has never lost a charge yet I let the truck sit for these past 3 days and today I started the truck and it started right up I don't see any dimming lights except it has a whining noise and the battery light didn't come on immediately I let it run for 5-10 minutes before it came on; I even drove it around the block and the whining noise gets louder every time I step on the gas. To me it's either I need new alternator, tension pulley is bad or the idler pulleys are bad but they turn fine.
Ford 7.3L Power Stroke (1999-2003) :: Battery Light Flicker In Time With The Idle Of Truck
I bought a 7.3 f250 with 300k mi. It had a battery light on but didn't show any signs of trouble. Eventually started dropping volts a few days later and I replaced the alternator. The light is still on and flickers in time with the idle of the truck and sometimes goes out when I'm on the gas pedal. Some nights when the lights are on the voltage drops ever so slowly until its drained. Why the new alternator didn't fix the problem? NAPA's scanner says the truck has 12.4V at idle and 12.1V at idle with the lights on. Batteries are relatively new and test fine, dual Interstate Mega-tron Plus batteries-top of the line.
View 6 RepliesFord - Escape :: 2004 - High Pitched Idle
Earlier this year, I had to have my alternator changed out in my 04 Ford Escape - the local shop installed a re-manufactured part to save me a bit of money (which was fine with me, considering the brand new alternator I had had installed needed to be replaced after a year and a half). For the most part, the car works fine, but when it is idling (especially after a cold start) there is a constant high pitched "whir" sound. I have also noticed the lights dim a bit when more systems are used, but nothing ever stops working. I have had the alternator checked 3 times now, but each time it is charging the car normally. What could be causing this?

View 9 RepliesSanta FE SM (2001-06) :: High Pitched Whine - Parking Brake And Battery Light Came On
First I noticed that the parking brake light and battery light came on, which would indicate an alternator problem. I took it in, they cleaned up the engine, replaced a few hoses and said the alternator was fine. Two days later I'm driving home, I make it to my driveway and the battery dies. I was able to charge it up and dive it back to the station where they told me the alternator had burned out...
A few days later I notice my brake lights weren't working, but that was just a blown fuse.
Starting today, there is a high pitched whine when I'm driving. I can barely hear it when I'm idle, but going up to 20 or 30 it gets very loud, then kind of dies off. It definitely gets louder when I'm accelerating, vs going a steady speed. As I was driving earlier, the air bag light came on for a brief second, and I didn't think anything of it, until later tonight when I was driving home and it came on again, but this time it stayed on.

Golf VI R :: High Pitched Whining From Rear Of Car?
I've got a steady and consistent high pitched whine coming from the rear of the car. It's only audible when the car is running idle and/or at a standstill, A/C and radio off. Also can't be heard while driving. I've ruled out any rear diff issues and thinking it might be the fuel filter. I recall noticing the sound soon after getting the car, however it's gotten more prevalent recently.
View 2 RepliesPrius (Gen 2) :: High Pitched Whining Sound After Shutdown
Yesterday after a 45 minute drive home (GA and above 90 degree heat), I noticed a moderately high pitched whining noise after shutdown. The noise continued for about 5 minutes. From my understanding, the inverter coolant pump redistributes the coolant after shutdown and I have heard a humming noise previously which I assumed to be this action.
