Prius (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.

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.
Ford - Thunderbird :: Fan Coming On Occasionally / High Pitched Whining Sound
My 2003 T-Bird (52,000 miles, original owner and only driver) has a fan coming on occasionally (in front) while I am driving. No warning lights. It goes off when I shut off the engine but then I get a high pitched whining sound (in front) that shuts off after a few minutes. I took into the dealer and they checked out my radiator level (full) but found a pinhole leak in the radiator hose. "The engine is not overheating, not to worry, fan is electronic and is normal". I don't think its normal since this is the first time its doing this after 9 years. Could this be the same problem as Elaina is having: An evaporative emissions pump sticky valve or leak in this system?
View 5 RepliesSubaru - Xt :: 2005 - Whining Sound With Acceleration Recently
I bought my car new. It began having a whining sound with acceleration recently (at 98+ thousand miles). A garage replaced the power steering pump, THEN told me I needed a turbo. No problem to drive it to dealership, waving bye-bye all the while. By now, the car is no whining, it is chugging along making strange metal sounds. Dealership confirms that I need a turbo, and also by the way, an engine. There is metal in the oil pan. I have now seen many blogs, complaints, etc. on line about a defect in the turbo on this car that causes oil starvation to the engine. Question: With metal in the oil pan, is there any hope in flushing the engine, replacing the turbo, and getting some mileage out of it? It has 99,000 miles. Has Subaru given any "good will" compensation for this? There were service bulletins about it.
View 5 RepliesPrius (Gen 2) :: Loud Chirping / Whining Sound Under Acceleration While Driving
I have a 2008 Prius with 111,000 miles on it and lately, I hear a loud chirping, whining sound that is louder under acceleration and seems to vary only according to acceleration or deceleration. Acceleration makes a louder sound. The noise does not occur when vehicle is cold and first driven. It's only after it's driven for awhile and things are warmed up but then again, it doesn't always do it even though it's warmed up. Not sure I could reproduce the sound if I brought it to a dealer for service. When the noise does start up, it's very apparent and loud and then, after awhile, it goes away temporarily only to start up again.

My 2004 V6 has about 21,000 miles, and has run perfectly from day one. However, the last few days I've noticed a whining sound which I think is from the transmission. when I first start out, at very low speeds. I don't think it occurs at higher speeds, but I'm not sure because of road and engine noise. The noise doesn't really bother me--goes away quickly. But is this something I need to have the dealer look at? It's still under warranty.
View 1 RepliesPassat (B5) :: Whining Transmission Sound / Lack Of Fluid?
My 99B5 1.8T Auto is making some weird sounds... I heard that it is either a serious issue or just a lack of fluids. Sad to say that the same sound was coming from my Toyota Highlander right before the transmission died on it (I know, completely different vehicle; but same sound). What I can/should do about it. The sound starts in 1st, loudest in 2nd, and begins to leave around mid 3rd gear. (Again, same as the Highlander), I don't want this car to die too.
View 2 RepliesGolf 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 RepliesPassat (B7) :: Whining Sound That Increases With RPMs After Stereo Replaced
After having the stereo replaced over the weekend, our car has now developed a whining sound that increases with rpm's. My wife didn't notice the whining sound until today, which means the car was driven at least around 100 miles between the installation and this morning when she noticed it after leaving the house.
It sounds the same as I've heard before when the alternator makes a noise through the speakers, however the sound doesn't sound as though it's coming through the speakers. With the Pioneer unit that we have, you can turn off the audio source, but I don't really see a way to completely turn off the unit.
I went down with the thought of removing the fuse for the audio system, however the manual states that at the time of writing, they couldn't document all of the fuse mappings and to refer to the dealer.
We have an appointment in the morning to have the dealer check out the noise, but if it ends up being the stereo install that caused the problem, I'm thinking they may charge me for the service visit.
Which fuse controls the stereo so that I can pull that to see if the noise stops?
Accent RB (2012+) :: High Pitched Whining Noise?
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.
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.
GTI 337/20th Anniversary :: Low Pitched Whining Noise Coming From Engine
I just picked up a 20th about a month ago. It has 50k on it and recently I've noticed a faint whining coming from under the hood, most noticeable under idle and it changes pitch when I turn the wheel. I check the P/S fluid and it was low so I topped it off and I believe it has improved a bit but not too sure because I haven't gotten a chance to drive it yet. The steering does feel a little heavy but I figured that's normal because, well it's not a cadillac.

View 3 RepliesSonata NF (2006-10) :: High Pitched Whining Noise While Driving The Car
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.
Tiguan :: 2012 - Low Pitched Whining / Buzzing Coming From Engine
Over the last several days I've noticed a faint whining noise coming from the engine when I pull into the garage. Sounds similar to the noise you hear when you keep an elevator door open for too long.
This is the first turbo engine that I've had so I'm not really familiar with the sounds it may or may not produce, and whether this is normal behavior.
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.

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..

The car still performs fine, but I have noticed a slight decrease in acceleration speed..
