Sonata I45 (YF - 2011+) :: 2013 - Humming Noise From Engine When Accelerate Or Car Decelerates
Aug 2, 2013
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?

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.

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.

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.

I just purchased a 2011 Hyundai Sonata with 126K miles on it and so far it has been okay. The only thing I noticed is a whining noise when I go to accelerate and the other day I went to put the car into reverse on the odometer it did not display what gear I was in nor did it illuminate on the gear shift whether I was in drive or not.

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?

I notice some faint knocking from the engine when I accelerate. I notice this symptom during summer months.
What to do? 2012 2.4l engine ...

Every time when i accelerate, there is a 'blade spinning sound' coming out from the engine, i noticed it when my car hit around 5k miles, now it's about 7300 miles. any idea what that is? could be the belt problem?
The second noise is a constant 'locking' sound comes from back passenger side. when I locked all doors, (especially in quiet night makes noticeable) about every 10 minus, the door kept making a 'locking' sound, it sounds the latch and the lock can't fully attached each other, and the door has to constantly reboot the auto-lock system.
What are the issues of these two annoying sounds?

Remote App will not turn engine off, just start it. How Dumb is this to design car to remote start but Not Remote Turn Off???

So about a month ago my 2013 Sonata GLS started to make some clunking noise going over the littlest bumps over the road from the front end on both right and left side.
I brought it to one mechanic and they said the rack and pinion needs replacing which is an expensive fix. I couldn't believe that was the problem as I had no leaks and it was on their solid. I ended up taking it to my uncles mechanic and he stated its the stabilizer links on the front right and front left wheels. My way to work has a lot of bad pot holes... so I'm hoping that the stabilizers are actually the problem.
Anyways, tomorrow I will be bringing it to the mechanic to have them both changed. I know a lot have been complaining about this issue and instead of replacing the rack and pinion, I thought I'd try and see if it actually is the stabilizer links and provide a fix for some of the sonata owners on here.

When going down the road I notice a rattle noise coming from the steering column area. I took it to the dealer a week or so after noticing it. I purchased the car brand new and like I said I took it to the dealer a week after purchasing it and they said they could not find anything and said they zip tied the brake lines or some bs hoping that would solve my problem.
It is now kind of obvious and I am going to take it back in to another dealership that has a better reputation.
I took a video last night so you can hear the noise I am talking about.

Heard wicked vibration from front of car (almost like I hit something and it jammed under car) pulled over to realize sound was still there when stopped. after a few seconds realized it was the fan running (on setting 4) now a couple days later sound isn't as bad but still vibrating, doesn't matter where it's blowing (feet, chest, windshield). I bought sonata 20 months ago and has just under 23000 miles...

Looking for pictorial descriptions / videos on how to replace the CV axles on 2011-14 Sonata 2.4? Mine starts developing clicking noise under tight turns about 10k miles ago but the boots are absolutely fine. I just hope to buy some time on it before I can confidently replace those axles myself as I only have limited cash.

I have a 2013 Sonata SE without about 41K on it. I got the oil changed back in May, and a few weeks after I discovered that it was leaking. I took it back to the oil change place and they ensured me that they cleaned up the mess they may have left behind. A month or two later, I believe the engine is still leaking. I've cleaned up two significantly huge puddles of oil, yet the dipstick says the oil level is right below the dot under the full mark. I checked to see if the oil filter was dirty, meaning the leak would come from there if the wrong filter was installed. The oil filter is clean.
There is also a clear fluid leaking out of the engine now too. I thought it was water, but it has a bitter taste to it. It may be the air conditioner, but it has never once spit out water like this since purchasing the car new in October of 2013.
My engine also gets hot much quicker than it ever did before. I can move the car a few feet after starting it up and it will go one notch below halfway on the temperature gauge. It has never exceeded this temperature, but it sure gets there quicker now after this oil issue began. I can also tell when the car is feeling a little sluggish in terms of acceleration, and right now, it's certainly feeling sluggish. The 2.4L isn't as peppy as it usually is.

I got the 2013 sonata gls, 5700 kms.
I live in southern Ontario, in Canada and the weather is starting to drop here in the mornings and nights.
The mornings are not 0-3 degrees Celsius and at night a little bit colder.
I have notice that when I start my car in the morning it seems like the engine takes a little big longer to start. It takes no longer than 2 seconds to actually start, it just sounds like its struggling a bit more.
I notice once i drive the car for a bit, park and then start the car again it seems like it fires up quicker and without ease.
Is this due to the drop in weather? or something else at play here.
Also it seems like in the mornings when the car has been sitting for like 9 hours, after it starts the engine sounds louder than usual.

I just bought a 2013 Sonata. There is a whistling noise from the passenger side vent closest to the door that appears at about 70 mph when in MaxAC mode. It is high pitched like a venturi. It goes away when switched out of MaxAC mode or when the speed drops below 70. I am guessing that it has something to do with the outside air being squeezed off.

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...

I was installing a new engine mount the one on the tranny and one of my jack stands failed on me, luckily I wasn't under the car. I always put a tire under the car just in case and it worked for me, but now whenever I accelerate I have a humming/whining noise. Can this be the transmission? This is on the 07 Camry 4 Cylinder.
