Sonata I45 (YF - 2011+) :: Starts Then Cuts Out With Humming Noise
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.

View 4 RepliesSonata 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?
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.

I have a 2011 Sonata. Recently, I have heard a faint knocking sound when I'm in reverse. It doesn't do it all the time. When I took it into the dealer, it would not make the sound while there. What causes that sound?

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?

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.
View 5 RepliesSonata I45 (YF - 2011+) :: 2013 - Rear Humming Or Roaring Noise
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.
Sonata I45 (YF - 2011+) :: 2013 - Humming Noise From Engine When Accelerate Or Car Decelerates
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?
Chevrolet - Suburban :: 2002 - Faint Humming Noise Coming From The Rear
I have a 2002 suburban . I have a humming noise coming from the rear . It starts at 45mph and then goes away at 47mph. I hear it again between 60-65 mph then goes away . This is a faint sound . When pulling a trailer the sound is much more noticeable and more constant from 55-64 mph . When I let off the gas the sound is still there and fades as the truck slows. Am I dealing with a bad tire ( I plan to rotate them to see if that is the cause ) or a wheel or axle bearing ? To note I replaced the front wheel hub/bearings just about a year ago .
View 2 RepliesCamry 2012+ :: 2013 SE With Faint Droning / Humming Sound - Suspension Noise?
I love the car, but had a few small gripes, including ride firmness and road noise. Well, the ride firmness has definitely calmed down a great deal over the first 3500 miles to now I find it has a perfect balance of handling vs. comfort. It's firm, but the bumps are not as jarring as those first 500 miles or so. I'm very happy with it.
The 2nd issue I hd/have, is road noise... or rather... I think... suspension noise. It's a faint droning/humming sound that I think comes mostly from the rear. You can start hearing it at 20-30mph on all but the smoothest of roads. The noise seems to be *in addition* to the very, very minimal tire noise I hear from the very nice stock Michelins. The harsher the road, the louder the noise of course.
My guess (and it's only a guess?) is that the metal bushing ('pillow ball') in the rear along with the other firmer suspension parts are the primary cause of this noise.
So I have tried a couple of things to try and counteract this noise:
1) Put D'amplifier Pro in the trunk - Got down the bare metal and put the stuff all of the place back there... Above the wheel wells also.
This did not stop the noise I hear.
2) I then put some sound deadening foam mats above both rear wheel wells.
This did not work.
The strange thing is that this noise is pretty faint, but unmistakable... however if I move my head forward (say, right in line with the steering wheel) 2 feet.... I barely hear it. But when I move back to the normal driving position, there it is.

Sonata I45 (YF - 2011+) :: Big Jerk And Rather Loud Noise When Shift The Car In Reverse
Today while backing into a spot at work (parked on a flat surface) my 2011 Sonata GLS automatic tranny, when I went to shift the car in reverse felt a big jerk and rather loud noise from shifting.... Haven't heard it since.... I think this happened to me once before many months ago... also on a side note why do I hear a almost a crunching noise when I am steering the car in reverse... I just had my car in for a oil change too.. I'm the only driver and owner of the car it has about 42k on the odometer.
View 17 RepliesSonata I45 (YF - 2011+) :: Unusual Engine Noise / Loud Growl
I purchased a 2011 Sonata about 6 weeks ago. I like almost everything about it, but the engine is very noisy. I'm not talking about a loud growl when you accelerate, but it's almost sounds like there are 2 frequencies sounding at once. It's higher pitched and at times sounds like pinging or clattering. It's very hard to explain. Unfortunately, sometimes it's worse than others and when I've taken it to the dealer, it's not at it's worst. The dealer I purchased it from told me that it was normal, even though I drove another 2011 on their lot that did not have the sound. Another dealer told me that it was a loud fuel pump because of the high pressure of the injectors and that Hyundai is aware and is working on a new "cover" that should muffle the sound. When I contacted Hyundai directly, they did not know of any new "cover" being developed . Assuming I've described it well enough to know... The only thing I know to do is wait for it to get consistently worse, and take it in again.
View 35 RepliesSonata I45 (YF - 2011+) :: Loud Thunk Noise When Shifting Out Of Park
I've got my 2013 sonata and have noticed over the past couple weeks that after the car has sat for a while and I shift out of park that it makes a thunk/shifting sound that's coming from right below the car. I think it's coming from the gear shaft but I'm not a car expert so I can't be sure, it's more prevalent when I shift into reverse. What it could be? The car is still completely under warranty so I'm fine with making it the dealer's problem.
