My 07 SCREW 5.4L 4x4 has 77,000 miles and has a high pitch whining noise on front right side of engine. Sounds worse in the cold,increases with RPMs.
View 5 RepliesMy 2007,4.6 is making a whinning noise from the front of the engine around the idler/tensioner/alternator. What I have read it might be a problem with the alternator getting cold, I forgot to mention it's cold up here. Fixed by changing the alternator and did the noise come back as it seems to be a design problem?
View 12 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.
My sons 97 LeSabre runs and drives like a top most of the time. Twice now though over the last three months it has died on him. Both times the car stalling out has been preceded by a high pitch whining noise that seems to be coming from the fuel pump. The first time, it would restart and run for a few minutes with the whining sound then die again. We towed it and let it sit a couple days and found that cleaning the MAF sensor may fix it. We did this and it worked.However, yesterday afternoon he and a couple friends ran into town, about a 20-mile drive, to run a couple errands. Drove around in town for about 30 minutes and it started the high pitch whine from the tank again and made it a couple miles across town before it died again. Pushed it around the corner to a gas station and parked it. A few hours later, my wife and I went to go get it, didn't know if I would have to push it or tow it, but I turned the key and it started immediately with no whining noise, so I drive it the 20 miles home without incident. The outside temperature yesterday was in the mid 90's and humid, and thinking back to the first time the car did this, the weather and circumstances were almost identical? When used to go to work out, or to work, or just little drives around there seems to be no problem. The car has even run this 45-50 mile round trip without incident numerous times, but at different times of day with cooler temps, and some lengthy waits between driving times.Does this sound like a fuel pump or sensor that could be failing? And why would it only act up under high temp situations? Almost like it was vapor locked, it had plenty of fuel, and didn't make a difference earlier in the heat even opening the gas cap to relieve any pressure? Completely stumped here?
View 5 RepliesI have a 2007 Sonata, 2.4L 4cyl. and it is making some weird noise as of late. I have done some research and from what I have read it seems like it may be a bad engine mount. One thing to note is that the noise really only happens when the car is cold and hasn't warmed up yet or on a cold day.
Basically the best description is that the noise is a high-pitched rattle/vibration noise. The noise seems to match the vibrations of the engine but doesn't seem to get more intense if I rev the engine. The noise does get quieter if I put it in neutral but it is still there. The noise also happens even if the car is parked and off, and I do something like shut the door or trunk. I haven't gotten a chance to get in there and look under the hood myself to try...
'05 F150 5.4 Sounds like a whining noise from the front end when turning to the right or going straight. Goes away on left turns. Thought it was tire whine but put originals back on and got same thing. 13.5x35 verses 275 Truck has a Fabtech 6" lift. Right CV axle seems tight, rotor assembly replace 2k miles ago. Any other option before going into front diff?
View 2 RepliesOver the weekend I discovered that the rarely used front passenger's window makes a consistent, continuous, low-pitch grunting noise while being raised up. You know like the motor is about to give up. It hasn't slowed down compared to the driver's window.
View 1 RepliesI've got a 2006 Prius - bought new in 2006. Yesterday I started to hear a high pitched whine or hum from what sounds like the front right side of the car. I hear it when the car reaches about 48-50 mph and seems to increase as you go faster. Once I let off the accelerator the sound slowly goes away. I know there are a lot of noises from the Prius, but this is one I've not heard before.
View 2 RepliesI noticed my engine whine more than it usual since the last few days. So, I took it to the dealership and have them check. They said that it is the idler pulley going bad.
View 4 RepliesAny way, my 2007 Sonata with 57,000 miles just developed a whining noise on the right side of the engine compartment. It sounds like it is concurrent with RPM and I thought it might be the alternator, the drive belt or some pulley. I have even seen on the general internet that some others had a bad oil filter. To me, the noise seems to be coming from the alternator area. It is a relatively high pitched noise that almost sounds like an electric motor. Would love to get it fixed. I am nearing the 60,000 max on replacement from certain items and do not know if the alternator is covered.
View 4 RepliesMy 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 RepliesI have a 2011 F-350 Diesel. It started making a strange whining sound when I start it in the morning. Very random and only does it when it's 0- -4 c. Took it to the dealership and they said its the cooler fan clutch. Got it replaced yesterday, and this morning I started it up and the whining sound was back. It also had a weird vibrating sound. What it could be?
View 10 RepliesCar wouldn't start, would just kind of do a high pitch whining. Bought new battery and still does it. It might crank right up or take up to 5-6 times. I'm a second owner and I believe it is the starter.
View 12 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...
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 RepliesThe car required a new water pump, the mechanic suggested to also replace the serpentine belt because of age - after a week the car made high pitch noise when started, the noise stopped after the initial start-at the shop it was explained that a new serpentine belt requires tightening after the car has been driven for a while - like a week- is this correct or was the belt not installed correctly....
View 11 RepliesI purchased a new 2011/2012 Santa Fe (R2.2 VGTi Auto 7 Seater GLS AWD) recently and noticed a high pitch noise on the audio system. This high frequency disturbance is audible with the engine off (eliminating the alternator as being the source). This is also present with the volume set to a minimum.
View 14 RepliesI just drove away in a new 2014 Dodge Grand Caravan - had 106 miles when I took title at the dealership - and immediately noticed the most annoying high pitched whine or whistle. It seems to occur under 2000 RPMs and starts around 25mph. It continues until about 45 mps and then either becomes less audible behind the engine noise or stops - hard to tell. When the car slows down, it comes back -- most of the time. It changes in pitch as the car goes faster and as it slows down.
It has been so loud at times that I think it's a police or ambulance siren and I have gotten ready to pull over. It does not happen in neutral when I rev the engine - the car has to be moving. Turning the wheels doesn't seem to make a difference. I am going to take it in to the dealer but I suspect they will just laugh and say that's how the car sounds. I've never had a car that had such an annoying soundtrack - and I've rented about 5 of these minivans over the past 3 years and never experienced this, either.
My 2007 Prius Touring creates high pitch Squeak/Whistle sound while accelerating and braking, But if I put the car on neutral then the sound completely goes away. I have all the holes covered on the both side mirrors and this still occurs. The sound is constant for as long as I accelerate and Brake and the intensity varies with how hard I accelerate or brake, It also does that during regen braking when I leave the accelerator. What could be wrong?
View 2 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?
I need to diagnose an issue I've had with my 2007 Prius with 79,000 miles on it. Several months ago I noticed a distinctive whining/humming noise coming somewhere from the engine compartment of the car while driving. The noise may be present at lower speeds, but the volume of the noise appears to increase proportionately with my acceleration and as such is most noticeable at highway speeds of 50 - 70 miles per hour. As I accelerate faster, the noise level seems to increase. If I take my foot off the gas and coast, decreasing speed, the whining noise gets lower in volume. I believe I first noticed this noise about 6 months ago, but wasn't more proactive about it like I normally would be because at first the noise didn't seem overly loud and my extended warranty unfortunately was up once I hit 77,000 miles. Now 6 months after I first noticed the noise, I believe it's definitely louder than it was when I first heard it, so much so that I can pick it out over the radio being on at a decent volume.
After checking some forums I thought the culprit might be a wheel bearing. I took it into a local Midas shop at they informed me that my passenger-side front wheel bearing was actually breaking apart in pieces. Obviously I had that wheel bearing replaced but I was also hoping this was the source of the whining noise. Unfortunately that wasn't the case as driving it home the noise was still present. They also said the tires were not balanced properly (from my Toyota Dealership no less when I had them install new tires) so I had the tires rebalanced as well. They did take the car for a test drive but probably stop looking for issues with the car as soon as they saw the wheel bearing in that condition. Also that shop does not specialize in Prius' or hybrids so they might not be able to notice the noise that shouldn't be there like I can.
Other than wheel bearings, where this noise could be coming from. Some posts on here possibly pointed to the ICE water pump or transaxle fluid (which as far as I know has never been replaced since I bought the car new).
