Ford - Focus :: 2011 - Loud Humming Sound From Engine?


Aug 17, 2014

After I took my Ford Focus 2011 to the dealership for a free oil change I noticed a subtle, low hum coming from the car when I hit speeds past 40mph. At first it sounded like the engine of a louder car driving near me so it took me a couple days to realize that it was actually my car making the noise. I intended to bring the car right back to the dealership to complain about this but I kept getting preoccupied with my studies for my summer courses. It's been roughly 3 weeks now and the low hum has gotten a lot louder now and can be heard over music.

The noise begins when I approach 40mph. The noise is probably at its loudest at speeds of 40mph-70mph. The noise is made even when I am not stepping on the accelerator or using the breaks. I haven't tried putting the car in neutral at those speeds. What might be causing that noise? Although I don't really trust the dealership since my car seems to manifest a new problem after each visit.

Sonata I45 (YF - 2011+) :: Loud Humming Sound Like Compressor Or Something Kicking On And Not Fully Engaging

I took my car in to get this checked out, but they say they can't hear it.

Sometimes when I turn my car on right after I turn it on, there's a loud humming sound like a compressor or something is kicking on and it's not fully engaging. And it only makes the sound for maybe 3-5 secs. Sometimes it won't happen when I turn the car on, but when I'm driving and I let off the gas and go to touch the brakes, it'll start.

The best I can describe it is a 'hum'...but it's loud, and I can feel it as if it's near the gas pedal right behind the firewall.

Dealer thought maybe it was the ABS switch testing itself..but they could never reproduce....I got in after they replaced my rims and checked it...and it did it 4 times when I started it, then turned it off. He came out to check, and it was almost as if you couldnt hear it outside of the car.

So, what the sound might be...I can't reproduce it anytime I'm there. Figures...... but I hear it almost daily. He put some foam tape on the firewall behind the gas lines saying the 'pulsing' from them might be doing it...but it did it again this morning.

Chevrolet - Malibu :: 2011 - Loud Humming Noise?

My 2011 malibu has approx. 20,000 miles, it makes a loud humming noise that is very annoying, can't even hear someone talking and must turn up the radio. It gets much worse when you get up to 55mph and above. I thought it might be the tires but they look good, but could it still be the tires?

Sonata I45 (YF - 2011+) :: Loud Ticking Sound From Engine When Idle

My 2011 2.0t has developed an odd ticking sound from the engine bay that is audible when idling. I haven't been able to pinpoint the source of the sound because once I drop the vehicle in Neutral it goes away although sometimes I do hear random ticks when I do this. The ticking sound is intermittent and sometimes I hear nothing.

In the video at 11 seconds the ticking starts. At 18 seconds it ends as I drop the car in neutral. What this sound could be? I'm going to try to hit the handbrake and check myself or have someone in the drivers seat while I go check but have yet to truly pinpoint the source of the noise.

Alero :: 2003 - Loud Humming Sound At 40 MPH+?

Our car is a 2003 2.2L 4 Door. 132,000 miles.

About 3 days ago it started doing this thing where once we hit somewhere between 30-40 mph, it started making a low pitch humming sound. At 40 MPH+ it is very loud. To me it sounds like an airplane, I don't know how else to explain it. There is no shaking, though sometimes I can almost feel the vibration from the humming at my feet. My husband says that the higher the RPM's, the louder and slightly higher pitched the sound is. If we go below 30 MPH it stops.

We were a little late on our oil change and I assumed that was it, but got it changed today and it's still doing it. Other than that, about 2 and a half weeks ago, our rear driver side tire went flat. My husband was in the middle of no where on the way home from work so he used Slime and that fixed it (never went to get it repaired because we didn't have the time and it didn't go flat again).

Could it be that the tires are not balanced correctly because of that, and it is causing the humming?

Also, this may be completely unrelated but: The only other problem we have had/still have with the car is that about 2 years ago we drove from Texas to Nevada, and at one of our stops the coolant dumped out (did not overheat/no other issues). Took it to 2 different shops and they couldn't find anything wrong with it. Drove fine until 6 months ago driving from Nevada to New Mexico, it did it again, but this time it also overheated. The mechanic said it was the water pump. Replacing the water pump (which is expensive!) did not fix it, so without consulting us they also changed the thermostat. Charged us for both, told us it was fixed, and about 2 month ago it did it again, but did not overheat/no other issues again. Hasn't done it since...seems it only happens on long drives. Anyway, I don't think it's related, but I thought I'd mention it.

Subaru - Outback :: Loud Low Humming Sound

This is a question about a Subaru Outback, but probably pertains to many other cars as well. I have a 2006 Subaru Outback with 112K miles. I bought new tires for it in May 2012, and in September 2013 I started to notice a low humming/buzzing sound while driving. I looked online and came up with 2 options - either the wheel bearings or the tires. Because the sound changed pitch depending on the road surface, I thought it must be the tires. I took it in for an oil change and had the mechanics check the bearings. They said the bearings were fine, but the tires were cupping and feathering badly because I hadn't rotated them, and that was the source of the noise.

I had them rotate the tires and do an alignment and went on my way. The sound slowly got worse - it peaks at ~65 MPH and then changes pitch above 70 MPH and is not so bothersome - and I started to lose gas mileage ( 4-5 MPG). On Dec. 30, 2013 I took it in for the next oil change and bought brand new tires - Bridgestone Turanza Serenity designed for quietness - and had them do an alignment, and drove away only to find that the noise is still there and I still have lousy gas mileage.

My next thoughts were the transmission or the catalytic converter, but since the noise doesn't change when I take my foot off the gas or put it in neutral I don't think it is either one of those. The alignment showed that the Caster on both front tires is off, but since both tires are off by roughly equal amounts I was told that this is not something to worry about. I do occasionally notice some vibration while driving or while idling, but it is intermittent and I don't think it has anything to do with the noise.

Sonata I45 (YF - 2011+) :: Squeal Noise From Front Tires / Loud Humming When Rotated

I bought my 2011 Sonata with 27k miles on it. After a while (few months) I noticed on occasion when turning I would get a screeching/squeal noise from the front tires. Only happened during certain turns (U turns I noticed where higher chance of happening).

I rotated the tires (Front to the rear, Rear to the front), and then there was a loud humming noise. I got it checked with the dealer and they confirmed tires were cupping (uneven treadwear right?) . So now its been 10,000 miles and the noise is the same. I just got an alignment done and there has been not much of a change.

So, other than getting new tires, should I get the tires balanced? Or just rotate them once more so that the rear return to the front again? Will I have to get another alignment done?

Ford - Explorer :: 1996 - Loud Humming Noise Then Engine Stalled

1996 Exp 4.0L OHV ... Wife drove it the other day, said made loud humming noise, then engine stalled. Drove it this am, did it to me too while idling in D with foot on brake... humms for about 1 min, and then stalls the engine... If I rev the engine, was still doing it... but came and went when I was driving then till I got her home...

I know there is a black plastic cap that makes a similar noise but not as loud, this seems like something else... and the fact it stalled the truck is bothersome... it started up then fine, but still. The only thing that is the same as when wife had it, is that both of these days are like under 10 degrees outside... So, me thinks MAP? or something else that doesn't like these REALLY cold temps? or??

Corolla / Matrix 2009-13 :: Loud Humming Sound At The Rear When Reaches At 40 Mph

I bought a used 2010 corolla and notice a loud humming sound at the rear when it reaches 40 mph. I figured it was the rear hub bearing assembly. I already bought a pair of Beck/Arnley 051-6262 hub assembly. I found two threads here about the removal/installation but did not say the torque of the 4 bolts behind the hub assembly. I read on the Toyota Manual that it is 74 ft-lbs. Do you think that this is too tight for a 10 mm back plate. The wheel/rims bolt torque is 76 ft-lbs but the nut is about an inch length. It is almost the same torque for an inch nut compared to 10 mm back plate. Is 74 ft-lbs right especially for an aftermarket beck/arnley brand? On the Toyota Manual, the 2003-2008 Corolla 4 bolt torque is 45 ft-lbs. The 2010 is 74 ft-lbs???

Sonata I45 (YF - 2011+) :: Humming Sound At Front End When Fan Is On

I've noticed that when I have the fan on...A/C on or off...there is a humming noise coming from the front of the car at approximately 900RPM - 1100RPM... At first I thought it was the A/C compressor but there's a sound even without the A/C on... the sound is like a motor running, low pitch sound...it is very noticeable when you are driving at very low speeds like when you drive around a parking lot looking for a spot... it is also noticeable when you are coasting to a red light or stop sign and the RPM's hit about 1000... not sure if it's the fan making the noise because it doesn't have enough lubrication or something of a bigger problem...

Santa Fe (CM - 2007-12) :: 2011 - Humming / Howling Sound At 55+ MPH

6K mile 2011 Santa Fe Limited front wheel drive V6 and I am getting a humming/howling sound at 55+ MPH and it is very annoying, not too loud but there. It is really bad at 75+...

The tires were road forced balanced and a alignment was done by the dealer. The Rear was way out of align but they supposedly fixed it.

I do not get any kind of vibration in the body or steering wheel but the humming/howling sound is terrible. Almost like when you crack one of the rear windows and you get that pressure sound...

Ford Focus 1.6 - Ticking / Clicking Sound From Engine Compartment

I need to locate an unwanted sound from my engine compartment. I am driving a Ford Focus 1.6 petrol engine/zetec (2000), mileage:166 000 km. It's best described as a clicking or ticking sound which is quite distinct. The sound seems to follow the "speed" of the engine.

Most likely the sound is coming from the drivebelt, and maybe from one of the tensioners which the belt is running on.
It's a visible wobble on one of the wheels but I am not sure if this is the case. It does not seem like the sound is originating from the engine itself but I am not 100% sure.

I attached a sound .wav file : ford.wav 1.03MB

Golf IV / Jetta IV :: 2005 - Loud Humming Noise From Engine At 75-80 Mph?

2005 Jetta. The car makes a loud deep humming noise once I hit about 75mph, and goes away once I get to about 82 or so. I've taken it out of gear and matched the rpm I get at those speeds, and I don't hear the noise at all. It's only when I'm in gear. What this could be?
