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.
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 .
I have a high pitched ringing noise coming from the engine and I can't figure out what is causing it. The only thing I can recall is that it started happening after I changed out all the spark plugs.
This is the area it is coming from...

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 3 RepliesI 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 1 RepliesMy 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 RepliesMy GF drives a '05 Camry V6 with 82k miles on it. Just the other night, out of no where my GF's car starts to have this high pitch whining coming from the engine.
I was about 20ft. away when she started the car and from there it sounded like the power steering was out of fluid.. made the exact same sound (any guy worth his whit knows the sound). After I opened the hood I realized it wasn't the PS. After a little trouble shooting the noise seems to be coming from the left side... thought it could be a belt at first, but after playing around I swear it's coming from the heater core/AC lines.
I can feel the vibration in them and when I was pinching them together and putting pressure on them sometimes the noise would lessen or completely go away. I had my GF rev the engine and one time (when I was holding the lines) the noise was completely gone for a few minutes.
I can't pinpoint the exact place the noise is coming from... but after googling it it seems that most of the time strange noises are coming from that area it's either the water pump bearing, alternator or TB.
I took a video, but you can't really hear the noise cause it's a crappy cell video.... but the noise is really loud.
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.
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.
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 RepliesUsually after I run the car in manual/sport mode, I begin to hear a high-pitched 'hissing/whistling' noise coming from the engine. It sounds like a vacuum leak. It is audible while driving with the windows down.
I am having problems pin pointing the source, but it sounds like its coming from the center block. What is the right direction to the leak? It starts exactly at 1500 and cuts off at 2200 rpm (while in gear). 1500 to 3000 rpm while in park..
I have a Takeda intake installed and I re-tighten the fittings.
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 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.
Need to determine the cause of a strange high-pitched squealing noise coming from the engine compartment of my 2008 Subaru Outback 2.5l automatic. The squeal happens only when the temperature is cold (below 32 degrees) AND I hit a bump. It happens more often the colder it is outside. The noise is definitely coming from the front of the car and seems like the passenger side but I can't be sure. It happens with the blower fan/AC both on and off so I don't think it is caused by that. It happens when the car is cold or driven for a while and warmed up.
It occurs at both high & low speeds. I checked all my fluids under the hood and everything is filled as it should be. There are no lights (check engine or ABS) on. Recommend any troubleshooting that I can try? I have not taken it to a mechanic yet as they might have a hard time reproducing the noise since it has to be below freezing and hit a decent bump. I attach a video that I took while driving last week on a 16 degree day and heard the squeal when I hit a bump. I had been driving for about 30 min when it occurred. I have more videos of the noise if needed.
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.
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.
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 RepliesWhilst driving on the motorway at the weekend I noticed a very load high pitched noise which seemed to be coming from the rear/centre underside of the car. It lasted for about 30 seconds and then went. It has happened before about two months ago and after the first instance I had the haldex and rear diff oil changed. On both occasions it has been very wet on roads with torrentian rain.
