Pump buzzing/humming noise varies depending upon whether accelerating, coasting, or decelerating. Sound is reminiscent of a dentist drilling my teeth. Is loudest while accelerating, hardly noticeable while coasting, and somewhat noisy decelerating. Had one suggestion that the FWD torque placed on the steering rack causes the different noises. Haven't been able to do anything to quiet it.
View 2 RepliesSo I went into my garage last night to shut the door. I heard a slight buzzing/humming noise coming from the car. I narrowed the noise to under the truck of the vehicle. It sounded like a fuel pump was running. I don't know when it started, but it was about 5 hours after the car was driven last. After a little research, I found this in the manual page 8:
"Approximately five hours after the engine is turned off, you may hear sound coming from under the vehicle for several minutes. This is the sound of a fuel evaporation leakage check and it does not indicate a malfunction."
I started my car and it stopped after that. Could this be The case of why some people have dead batteries on the 2014? Maybe this runs to frequently or stays on too long?
Was the warmest/hottest day of the year here so far and my black Prius had been parked in the sun all day. When I came to drive the car the a/c came on full power to lower the cabin temperature.
However, from the front of the car the two fans were making a really weird buzzing, humming noise (but were both spinning at high speed). Now I know a/c fans work flat out sometimes but I have never heard a noise like this before on a cars a/c. It almost sounded like the noise a jammed lawnmower makes, or some of the old lifts/elevators doors make. Almost an electrical buzzing noise of a solanoid but it was coming from the two fans.
Is this normal? Was it the fans or maybe the compressor or both? The a/c was working fine and was ice cold. When the cabin temperature reduced the noise reduced a disappeared with it. However, I did manage to repeat it by turning the a/c internal fan speed to full on a low temp setting.
I keep my 2015 RX 350 in the garage, and last night I noticed a humming or buzzing noise coming from it. I switched the ignition to accessory position and turned it off and the noise stopped. A search here turned up many discussions noting is is the gas evaporation leakage check valve and it is a normal function of the vehicle. My question, is this some sort of pump that is running and causing battery drain?
View 3 Replies2015 IS350 AWD ... Lately I have noticed on a cold start that when my idle is between 1000-1500 rpms, there is a slight buzzing/humming noise. It goes away if I rev the rpms past 2000 rpms and also when it drops under 1000 rpms. It's almost like a droning noise. I can hear it inside and outside the vehicle when the rpms are in that range. I feel like the noise is made at a certain frequency and it causes a vibration to occur.
View 3 RepliesI have a 2005 GLI tip-tronic. Bought used but the brakes are not that great. I know what the brakes should feel like since I did a swap for them on my GTI. I'm done brake pads /flush and cycled the abs pump to try an fix it. However on this car when I press the brakes I can here a humming/ buzzing noise. I'm assuming it the brake assist pump. Can this be eliminated or does it have to be replaced. The car stops just not all that great for it having the type of brakes it has.
View 1 RepliesOnce the car reaches about 80 miles per hour, a buzzing/humming noise is emitted from the front of the car. I can't tell whether it's from the dashboard area or the footwell area, but it sounds like it's coming from below. There seems to be an exact speed where the noise stops and ends. The car does not shake or vibrate when the noise occurs.
The noise has happened twice. Not coincidentally, those were the only two time the car has been above 75 or so miles per hour within the past few weeks. I have looked on some forums for similar happenings, and I found the answer could be bad wheel bearings.
Other problems with the car include a very-vibraty engine between 1000 & 1500 RPM, a gurgling noise at low speeds/idle, and harsh shifting from 2nd to 3rd gear.
I've posted a video on YouTube of the car making the noise. It's a little hard to hear the noise in the video: [URL] .....
Recently purchased a 2002 sc430 . After an hour of driving I began to hear a buzzing or humming coming from the backseat on the passenger side . Sounds almost like a fan. Car drives just fine but the buzzing is driving me nuts.
View 3 Replies2011 F-250 Lariat with 38,000 miles. What is the cause or source of humming or buzzing noise from the under the hood that starts once I turn the truck off and close the door? Lasts from 3-4 minutes and only started noticing it in the last two thousand miles or so.
View 13 RepliesMy 2002 outback tape deck, which I use primarily to listen to my phone via a cassette adaptor, has recently started making a very loud buzzing/humming noise. It does this with both my old and a new adaptor, as well as a standard audio tape.
I could try using a head cleaner on the tape deck, but my impression is that this isn't what typically would happen if the head needs cleaning, and I don't particular want to waste the time and money on a solution that I'm pretty sure isn't going to work, but I'm asking you all in case you know better than me (a real possibility). I just don't know if I should try that first, or if I should just go out and purchase a new car stereo that has either blue tooth, or an audio input plug so I can directly plug the phone in that way.
Also if I do go the way of replacing the stereo, is that generally a straightforward process? And would most replacement stereos be compatible with my vehicle, or do I need to be selective?
I own a 2004 V8 and when I have the air going I get a buzzing noise coming from the water pump or something. What is this and is it normal..
View 7 RepliesI have a 06 passat v6 with 34,5000 miles and with extended warranty,the car consumes about 14 mpg city and I noticed a humming noise coming from the back seat or bellow the trunk I am positive is the fuel pump, I will like to know if my poor mileage is related to the humming noise or should I take it to the dealer to have replace under warranty...
View 2 RepliesWhat is the solution to fix the secondary pump humming/vibration noise? I get this humming noise from my driver side center dash area and according to few other members, it's the secondary pump. Some dealer fixed it by moving it to the side a bit to stop the vibration.
My dealer told me that's false and it's normal to make that noise (never had this noise before) and if there is something wrong, VWoA will issue an TSB to fix it..
Well, they won't do anything until there is an TSB and I was wondering if it's a easy fix that i can do it myself??
Is it normal in these vans to here the fuel pump humming? I hear it when I turn the key on and while I am driving. It never gets quiet.
View 3 RepliesI have a 2005 F-150 supercrew 4.6L with appx 127,000 miles on it. Back in December i took the family to a drive in movie and left the ignition turned to the on position. I jumped the battery and drove a few miles home. The next morning when i tried to start the truck it would not turn over. There was a buzzing noise coming from the fuel pump but not enough juice to turn the truck over. This has happened a few times in the last couple of months but will jump and run fine for weeks at a time. I've taken a 2500 mile round trip to Texas with no issues. I took a 200 mile trip this past weekend and now it will not start. I'm thinking it could be the fuel pump relay? I went to the parts store and bought a relay but it's not the same size as the one in my Haynes Manual. The part from the store is the same size as the bigger relays in the kick panel fuse box but does not match any of the plugs. According to my manual the fuel pump relay should be a smaller relay.
View 4 RepliesI bought the car( like six months ago) there has always been a loud humming noise from the fuel pump ( I'm pretty sure it is the fuel pump anyways) not the normal whirring noise the fuel pump makes but a hum you can hear about ten feet away. Had no issues till just lately when the afternoons are well into a hundred degrees. That is when my car starts giving me issues. After one of these hot days on my ride home from work, I had just come off the highway and stopped at a stop light when I felt the engine bogging out, the engine stalled and I had to push it to the side of the road.
Its worth mentioning that this humming noise is much louder in the heat than the cool morning then when I turned the key to hear the fuel pump(auto fuel inject) it was louder than it has ever been, and would keep stalling on the way home, I had at the most a quarter tank of gas (gas boy is busted/stuck I think) the fuel pump is bad? Could it be the sock? I thought I read somewhere that my girl pump uses gas to cool down, and that having the tank any less than a quarter could lead to the fuel pump overheating????
The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?
View 3 RepliesOur 2012 camry se had a problem with the fuel pump running when the engine was off. Several hours after we came home I went into the garage for something and heard a humming noise. First thought was a distant neighbor using a leaf blower, then realized it was coming from the rear of car. definitely coming from gas tank area. Turned key on, then off and noise was gone.
View 6 RepliesI recently noticed a humming noise coming from the passenger side on my Mazda Protege 2000 ES . I suspected it was the water pump, so I took the car to my mechanic. He inspected the coolant reservoir and it was empty. He also checked the noise and the area were the pump is, and told me that the water pump had to be replaced.
My dad told me that his 1994 Sentra had the water pump replaced but none of these things had to be done and that it was unnecessary. But then I thought, every car is different.
I was in shock with how much the repair would cost, so he then gave me another quote with just the timing belt and water pump replacement for $503, but this time he said that he will not give me any warranty for the repairs because of the tensioner.
Recently purchased a 2002 sc430 with 80,000 miles on it. Car drives like a dream but I have a noise coming from the backseat. Rear Passenger side ,upper back area. Best way to explain it is that it sounds like a small fan???? Comes on here and there as I drive .
View 4 RepliesI have a very strange sound coming from the multi color display in the instrument cluster. Whenever the display is on (no need to start the car, just open the door) there is a humming or buzzing sound. Not very loud, but loud enough to get on my nerves.
