Sonata NF (2006-10) :: Humming Noise Pulsating On And Off
Apr 25, 2011
I have a 2009 Sonata GLS with about 45,000 miles on it. Lately when I am driving over 50mph it has been making a very annoying, high pitched humming noise. The noise seems to pulsate on and off. If I am going in a straight line, the noise is present, pulsing steadily. If I turn right, the noise speeds up and gets louder. If I turn left, the noise slows down or goes away completely. The noise is not super loud yet, but it is driving me crazy.
I took it into the dealership and they said it was a tire problem - one is worn more than the others (though not so much that it needs to be replaced yet)
From what I have been reading online, it sounds to me like it's a wheel bearing problem, and possibly the worn tire is a symptom of that problem. However I have also read that the average wheel bearing should last about 100,000 miles with proper maintenance. If it is a wheel bearing, it should be covered under warranty, shouldn't it?

I recently bought an used 07 elantra w/ only 34000km (21080 miles), the inspection came up fine but he said I would have to change the timing belt within the next year and he said both set of tires (winter and summer) are on their last season.
Yesterday, I was driving for the first time on the highway with it and I notice a pulsating humming noise at speeds of 110km/h and more (~68mph+). I read that I should try and turn to see if the noise is louder, I will do this tonight.
Could it be the bearing even if the car has only 34k or is it probably the worn tires?

My 2004 Santa Fe 2.4L manual transmission with 200,000km on it has this hard to explain noise when in gear and coasting. This is when my foot it off the gas and say I'm going down a slight incline. There is a pulsating humming noise, worse in the lower gears that coincides with the engine holding the car back. This only seems to happen during coasting and not when down gearing to slow down. And even when coasting if I press even ever so slightly on the gas so the engine is not holding the vehicle back, it goes away.
The clutch has never been replaced and I'm somewhat assuming it may be the clutch becoming worn.

09 i4 AUTO 47K miles ... When the car is running at around 50mph and if I give it very slight throttle (enough only to keep speed constant), I would hear this rhythmic humming noise. The hum rhythm has a frequency of about 1/2 second each. It is very muffled, almost like exhaust noise or tire noise. However, if I downshift to 4th gear, keep the same speed, and apply the throttle in the same way, the noise doesn't occur.

I recently bought a 2007 Sonata V6, and the brakes pulsate (when applied) at highway speeds, so I am looking to replace the front rotors & pads. I have been told that the OEM rotors/pads aren't great & that as a result many owners have a brake pulsating/vibration issue.

My 2005 Toyota 4Runner is the V8 version with 4 wheel drive. I'm getting a pulsating humming sound at around 70 MPH - woh woh woh. Thought it might be new tires but it stops the instant you let off the accelerator. Hard to pinpoint location but if I had to guess I'd say driver's side front.

In my 2007 Sonata, I hit a poorly placed high manhole cover in a dip in the road, in the dark, going 30MPH, whacked it good before I could adjust...
I then pulled the car over, it seemed to go dead, then the car did crank back up, the engine sounded much louder, like a loud rev/hum, not quiet like usual.
I next drove a mile to a c-store, transmission seemed OK, no leaks, did see a check engine light briefly, but it disappeared. Car cranked OK, headed home, same sound right at cranking and at moderate speed.
Finally, I jacked the car up on the front left, from research appears that the plastic engine shields got smacked good along the front and near the right tire and bent back quite a bit on the left side. There seems to be no other structural damage that my untrained eye could see, just one indention you'll see in a couple of the photos that I think is part of the car design at that spot.
Again, no leaks, no smoke, no caution lights of any kind now.
Photos are attached...
My Hyundai's engine now sounds like a Mustang! Hoping it's just the engine noise from these plastic covers now being bent/destroyed in some spots, exposing the engine and the typical noise you'd hear without them...

Folks, my '07 SE has developed something interesting, and it's being a pain to diagnose. When I'm driving freeway speeds, whenever I make a right hand turn, I hear a low hum, and feel a slight vibration in my steering wheel. I know wheel bearings tend to vibrate all the time when going bad, but this one has me scratching my head. It also won't do it at lower speeds.

Have this issue during full stops or at slow speeds?

I'm the second owner of a 2011 Hyundai Sonata SE 2.4L with about 79,000 miles on it. I've had it for about 6 months and I go to get into my car this morning, and my car wouldn't start.
It starts to start but then cuts out and does a humming noise. I don't know if that counts as "turning over" because its a push start, but there were no clicking noises like it was trying to catch, just the hum. It also started making this same humming noise when I turn the car "on" without turning on the engine.
Everything works, my stereo, ac, headlights, taillights. I even tried jumping it and that did not work. We checked the fuses and they all look ok too.
I also put the key in the manual key hole in the center console while doing all this just to make sure.
Although it looks like the car is on, after I try to start it, the lights on the dash go out and my meters all turn on just as if the car is on, but the engine will not start. I can even shift the gears from parked to drive, neutral, etc and power steering works.
Finally after about an hour of messing with it, I gave up and tried to shut the car power off, and it wouldn't turn off! I went back n forth between the two on modes for a good 5-7 minutes before it FINALLY turned completely off and I was able to lock up and leave it...
*I have also had issues before where one or two dome lights randomly turn on when i unlock the car (with them set to OFF at all times). Maybe this is a minor electrical issue that turned into a bigger problem from ignoring it?
**I DO have an aftermarket stereo and alarm installed FYI.

So I just got my sonata back from the dealer, they fixed an intermediate problem i was having with the starter solenoid when it rained. car wouldn't turn over when key was turned for about 20 clicks.. (free under warranty and got a loaner!) new starter and solenoid!
But when I got my car back i noticed a new humming coming from the AC (passenger side dash) when it was on high.. i never really noticed it before.. do you think this could be from the cabin filter? or the tech that worked on the car messed with the blower?
I was thinking about going back to the dealer and asking my service advisor about the noise.. and if he said it was normal i would walk over to the sales dept and ask to test drive one of their NF's to see if the AC made the same noise.. and either leave the dealer knowing it's a normal sound, or drive the test vehicle up to the service advisor and ask him why this sonata doesn't make that noise?

I have a 2011 Sonata Limited 2.0t. I get a humming noise that starts out faint but gets very loud. This happens with the ac on and while coming to a stop or while stopped.

Layely with my 2011 SE I've been getting a low pitch humming noise while traveling at low speeds, mainly going into a stop sign or light and searching for a parking spot. It happens with the AC off as well, not so much a vibration just a low pitch hum, also does it with foot off brake too as I just let it coast. Kind of annoying and want to make sure its good.

My 2013 Sonata GLS has a noise that is in the rear of the vehicle going down the road. I rotated tires from back to front and noise seemed to move to front. I moved them back to rear so noise would be behind me. This told me the noise must be the tires or wheels. The tires are a long way from being worn out so I keep running them. I have the stock alloy wheels but previous owner put 225/40R18 tires on car. Tires size on door jam label says tire size on this GLS is supposed to be 225/45R18.
Could it be the wheels and not the tires? Another possibility could be factory lug nuts on back wheels. I read in my street rod magazine that lug taper length must be shorter than the taper length on wheel lug holes. Lugs cannot be so long that lugs hit the wheel backplate leaving the wheels slightly loose and not centered leaving a slight tire wobble when driving. The article says the lug taper much be shorter than the taper in the wheels in order to snug the nuts. I did not switch the lugs when rotating tires to front. If this is the problem rather than tires or wheels, Hyundai had a lug supplier problem.

New Sonata GL owner. Just picked it up last week and I love the car. Great drive, great features. Only thing is I am noticing that there's a humming noise from the engine whenever I accelerate and when the car decelerates. It's not really noticeable during the day when the streets are busy and I'm listening to the radio etc., but at night when I'm driving on quiet streets its quite audible and it almost sounds like Diesel engine.
I read a few threads on this and people have attributed it to the direct fuel injection - is this humming sound normal? Do all sonatas sound like this? Or should I go back to the dealership and get it checked out?

Got a weird pulsating feeling right through the accelerator when I get to 40 through 45 mph. Tires are new (245/40/18) with approx 2K mikes on them. I guess I have two things to do rotate and balance or just balance. Hope it's nothing to do with the larger tires and messing up something in the car.

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?

Having some issues randomly in the car, the dome lights/headlights are pulsating. Like the power isn't there. I have LED's connecting the battery, so I am thinking it might be a problem with the ground on teh battery. I know I can eliminate everything but the LED ground.

When ever I change the temperature up or down there is a humming noise coming from the back of the glove box for a short time. Is there some kind of temperature motor back there?

I thought it was the tired due to the cold weather. But now it is warmer the noise is still there. Bareknuckes previously mentioned wheel bearings as a potential problem. The car is driving (sound-wise) like I have some huge mud-bogger tires on or like crossing a cattle-guard continuously. so loud (in the cabin) that sometime I forget to shift because I hear the humming rather than the engine.

My 2006 hyundai accent makes a humming noise while driving. it gets louder the faster i accelerate. I have checked the wheel bearing but they appear to be fine. i jacked the car up and tested the wheel by pulling and pushing back and forth at the 12 o' clock position and etc. no give in either wheel. i also held the spring and spun both wheels with no vibration. I also rotated tires back to front. when i did this noise seemed to be lower.But still there. I did hit a fallen sign on the highway going 70 mph. I am wondering if this may have damaged my tires or if it still could be wheel bearing. and there is no vibration in steering wheel or while driving. just annoying humming.
