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 RepliesI'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.
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.
"93 Subaru legacy 175,000 miles: Just picked it up yesterday after timing belt/water pump replacement. Now it makes a high pitched whining noise sounds like from engine, the mechanic called it a whistle, but it ain't no whistle and wasn't there before.
View 3 RepliesAfter 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.
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.
View 4 RepliesStarting 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 RepliesI 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.
Yesterday as soon as I started my car, I noticed a high pitched whining noise. As I drove, it seemed to stop, but as I slowed down and idled, it came back. After driving a couple miles, the battery light came on, so I turned off the AC, radio, and lights and it went off again, but as I sat at stop lights it would flicker on and off again.
View 4 RepliesI 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 .
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.
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.
My Accent makes a really bad whining noise whenever I give it any gas, so I took it to the dealership. The tech who looked at it confirmed my suspicions and said he thinks it is something with the transmission. I have the 6mt. He said the head technician will look at it tomorrow and determine if it needs a rebuild... I am just hoping they don't pull some crap and say I damaged it with my driving (because it is the manual trans and that seems like the kind of thing a dealer would say) and say it won't be covered under warranty.
View 13 RepliesI have a 2012 golf R with about 25500 miles. I'm getting this high pitch noise coming from the front of the car. I can only hear it with the windows down. It is intermittent, sometimes doesn't show up sometimes there. Gets louder when I turn right. What am I looking at? Wheel bearing? I'm on coilovers.
View 8 RepliesI'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 RepliesI recently noticed that I'm getting a high pitched whining noise after I drive anywhere then stop and turn off the car. The noise is a buzzing/whining sound that lasts about 10-15 seconds and then stops. The noise sounds like it's an electronic component maybe having to do with the transmission? What it might be?
View 7 RepliesYesterday 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.
View 10 RepliesSo 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.
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 RepliesOver 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.
I've got an unknown issue with my 07 Accent (1.6L):
There is a low tone noise coming from near the upper area of the engine. It sounds like air or fluid traveling through a hose. The tone of the noise has recently become progressively louder, so that it is noticeable over normal road noise when driving. The noise does not fluctuate in tone or intensity with changes in RPM. However, the tone changes to a higher pitched frequency, almost like a hiss, when the clutch is fully engaged and held to the floor, both when in gear and when not in gear.
What the cause may be? And potentially required maintenance?
