2003 trailblazer Lt . when the motor is running the high pitch noise is coming from the fuel filter / fuel line area, if i crawl under there whil itd running i can get it to change noises when im grabbing the lines and filter but but it seems like it changes thje most when i mess with the hose where you hook a pressure gage up to it or bleed it
View 2 RepliesWhen the car is cold & first started, the high pitch noise by the fuel injectors is the loudest. When it warms up the noise is reduced quit a bit.
I thought maybe the fuel injector O-rings are bad, but the car idles and runs fine ( no error codes). Maybe the intake manifold gasket, but the car idles and runs fine. It is a weird noise.
Sitting in parking lot listening to ipod thru aux port opened door to access door pocket and sound system went nuts. I now have a high pitch noise coming through all speakers on all settings even with audio off.
View 8 RepliesNew 2012 SE, I noticed a high pitch noise coming from the rear side of my car. The high pitched noise/whine happens as soon as the car is running, and continues until it is turned off. I can hear it every time when standing idle or at lower speed. So I brought it into the VW dealership, and my technician: "found noise described is the high pressure pump in the tank".
We tested another 2012 Passat SE and we found the exactly same(even louder) high pitched noise coming out from the high pressure pump. I was told by a service manager that it is a standard high pressure pump noise for 2012 Passat. Well I don't think that any high pitch ultra whine/noise should be a standard feature in any car...It is very,very annoying noise...
Whenever I start my R32, I have some high pitch buzz noise coming from the rear, stay and never go away while even driving.
View 16 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 a 2009 Tiguan 2.0t 4 motion and recently has started having a very high pitched squealing noise coming from either the accessory belt area or the timing chain. The noise is constant until you are under acceleration and then it goes away. The CEL came on but when scanned it said no codes. and now sometimes the CEL will flash and the car has been idling rough. What it may be?
View 3 RepliesI had an oil change done last week for my 03 trailblazer, and was getting valve tapping on startup after sitting 8 hours in the cold, it goes away after a few minutes. I stopped by today, and they looked through the maintenance records and noticed a new i.e., supersedes the old filter filter model had been used, they are going to pick up the old model filter and swap it out. I can get the part numbers tomorrow, but in 154 k I have never had such a noise. And it started day 1 after the oil change. 5w 30 as specs and level was full.
View 19 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 have a 2013 Prius. I was noticing a high pitch coming that I could hear when I had the driver side window down and the sound was reflecting against things I was driving by. It was strange because it didn't change pitch at different speeds, and it would be there most of the time regardless of whether I was speeding up or slowing down. And regardless of whether I was using the brakes or not. I've been told this is the sound of the inverter.
View 9 RepliesOur 2008 Honda CR-V w/120k one owner, always dealer maintained, vehicle has recently started exhibiting a little high pitch whine coming from the engine area which increases when you rev the gas. I checked the transmission dipstick and the level is just below the bottom hole (owners manual says it should be between the bottom and top hole). Would this make the whine? By adding some fluid should it go away? Is it okay to use a fluid other than Honda's?
View 3 RepliesI 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.
My 2005 F150 has developed an intermittent high pitch electronic tone that seems to be coming from the dash. Sometimes it comes on for a few seconds. Sometimes for several minutes. It never varies in pitch. It will occur even if the radio and fans are turned off. It will also occur if the engine is off and the key is just in the accessory position.
View 9 Replies I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?
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.
View 11 RepliesMy friend and I both have the MK4 R32. He had a bunch of stuff replaced in the engine. (a bunch of plastic parts that are super expense, the timing chain, something related to the guide, basically the plastics that holds the engine cushion/absorb) Anyways, his engine sounds great and quiet at the same time with a little high pitch noise when the RPM is hanging in between 1K and 2K.
Our cars were in the garage and I did the same thing and it sounded NOT quiet, a lot more noise than his. There was an obvious difference in noise coming from the engine with the hood open. I do have cams and a light weight pulley. Can that have an affect on the engine noise? If I am not making sense, then i should probably video record the sound or take it to the dealership for a check up. Also, I am at 93K.
I have a 2007 Prius 3 Touring Edition. I purchased it new in Dec. 2006. I have had NO issues with my favorite car of all time, and currently have 90,600 miles. I have noticed a high pitch for a long time coming from the transaxle during acceleration. The pitch is only present when MG1 or MG2 is engaged. The pitch stops in stealth mode. My finance also has a 2007 Prius, and her's does not make the noise or whine when I drive her vehicle.
I have changed the transaxle fluid at 65,000 miles, but I did not see the plug when it was changed so I don't know how much, if any, shavings were stuck to the magnetic bolt. If you are wondering, yes, the high pitched noise was present before the fluid change. Also, as I accelerate and increase speed, the noise pitch increases.
Is my transaxle displaying a tell-tale sign of imminent failure?
I have a 2009 Gen. II with 48000 miles on it and it started having a high pitch noise when driving. Thought it was wind noise at first but does it at low speeds also. When you roll the right passenger side window down you can hear it much louder sounds like it is coming from the right front.
