I have been noticing that the ballasts have been making buzzing sounds a lot lately. Is this something normal that is suppose to do? I have the slim ballasts from xenon supply.
View 19 RepliesWhen the engine is in gears say 1-3 (doesn't seem to work in neutral or park) when the engine rev's to about 2500 - 3000 RPM there's a metallic vibrating noise that almost sounds like a buzzing/chattering sound. When you reach over 3000, it goes away.
Here's the curve ball - it stops doing this when the engine is really warm. It only seems to do it when cold or it's been sitting a while. So - it's limited to an RPM range between gears 1-3, it goes away when it's warm.
I am inclined to think this is related to engine mounts... And here's why. It seems to only happen when in gear and we know that the engine changes it's pitch/stance when in different gears versus in neutral/park. So I think when it's in gears 1-3, the engine is tilted a bit and something is coming into contact with something (maybe my strut bar) more than it used to due to more slop/movement from my worn out engine mounts. As to why it goes away when the engine is really hot (driven for an hour or so) is because maybe whatever it is that's coming into contact with something else is (perhaps a hose and its clamp?) is much more pliable while warm and clears whatever obstruction it was hitting while cold? (a lot of speculation and creative thinking here).
Anyway - after the engine is super warm and I've been driving it I cannot for the life of me get it to do it... It rev's super smooth and not a hint of any bad sound.... 2011 2.0T Limited ....
I have a 2012 Sonata GLS with 3300 miles on it. I have noticed that now that the temperature has dropped to below 60 degrees I have annoying dash rattle. It seems to be based on the rpm of the motor (1200-1500 rpm). So every time I take off from a stop sign or stop light I have this buzzing rattling coming from the center of the dash. It sounds like it is in the upper part behind the radio. The wife drove last night and I put my ear on the passenger side vent by the radio and I could hear the rattle. I am just trying to isolate the problem so when I go to the dealership I can give them some decent information. I thought the problem was the cowling on the bottom of the windshield. In the center of the window it had warped up. They replaced the cowling earlier this week and the problem is still there.
View 9 RepliesSo recently I took in the sonata to get the inhibitor switch replaced at the dealership (faulty switch causes loss of the gear indication and the car doesn't move when in gear). After getting the car back, it now buzzes when I put it into reverse or drive. It never did this before. Is this normal after getting the inhibitor switch changed and if it will go back to normal after a while.
View 1 RepliesToday I went out to crank my Sonata SE 2.4. Pressing the ignition button only got me a buzzing and no turning of the engine. We've been out of the country for 2 weeks and the car has been in the garage since then. I have a portable battery booster that I attached to the battery and the car started normally. I drove it for around thirty minutes and switched it off in my driveway. Immediately tried to restart and it would not start. Boosted again and headed to Auto Zone to have the battery tested. Battery tested bad so I had it replaced. The car started immediately so I turned it off and tried to restart as a precaution. No go.... boosted again and cranked fine. The new battery tested out good so we decided that maybe the charge could be low or? maybe we just needed to run it some on the interstate.
I now had a cel on. So we get out onto the interstate and drive about two miles and the engine looses power, limp mode ?. Pull to the side of the road and RPM's at only 1500 with the accelerator to the floor. I was afraid to restart the engine that it would possibly not restart and I'd have to be towed.
Luckily, we were about two miles from the Hyundai dealership so we limped there at 20 MPH. The car is at the dealership now being diagnosed.
I cant recall if these sounds were there when i first bought the car, probably because i have the radio on most times. I think the buzzing sounds were present in the last month at least.
After i start up my car and even after idling for a while, i hear a buzzing sound coming from the engine. It gets louder when I accelerate. When I let go of the gas, the buzzing sound lags for a few seconds and then quiets down a little bit, but still can hear it in the background.
I lifted the hood up to listen more closely. I am not totally sure, but i think i can also hear a faint hissing sound ( sounds like leaking air?). I cant pinpoint where it is, but its around the engine.
I also notice that when I am idle, the MPG number in the dashboard is dropping fairly quickly. Like 0.1 mpg every 20 seconds. This is new and started today. I last drove it 4 days ago and didn't notice it happening then and i watch the mpg very closely every time i drive. Could there possibly be some gas leak?
We have changed the brakes and the caliper on the right passenger side of our 2008 Hyundai Elantra. When we brake, we a getting a grinding sound. We had to change out the caliper 2x before we got a working one. Now with a working caliper, we are still getting getting the loud grinding sound. We had greased and removed all rust in and around the caliper. The brakes are new.
View 3 RepliesI normally drive with my arm (elbow) on the armrest and my hand resting on the gearshift. I have an automatic 2013 SE and for a while I didn't think much of it but sometimes it just concerns me because it's almost everyday now that I notice it... bu there is some kind of clicking sound a I can feel it through the gearshift. It sounds like it's coming from under it or somewhere behind the dashboard (like behind the radio console). I hear it every 3 seconds or so.. it's very subtle so I mostly hear when at a red light... it kind of sounds like something stretching or expansion, sort of like the sound wheels (or the exhaust.. not sure which makes that sound) make after you stop driving. The car seems to be running fine and I have no other issues with it. This is more of an annoyance so far but I just want to make sure this won't turn into a bigger issue.
View 8 RepliesIs it possibly related to the blind spot detection system. I have had this happen to me once at an intersection (no lane change) and I thought someone was blowing their horn at me. My wife has had it happen on several occasions (never lane changes). This morning she was leaving he shopping mall at a stop sign and a car was coming down the cross street towards her (but not close) and there was this mysterious horn sound. I remember the salesman saying something about a warning sound when backing out of a parking space if a car was coming at you.
View 3 RepliesToday I woke up to go to work and noticed that I don't have any sound coming from my radio. At first, I thought the station might be having some issues so I tried a different station and still no sound. I switched to CD player and guess what...no sound. I tried XM and guess what...no sound. I tried bluetooth and guess what...still no sound. When I got to my destination, I shut off the car, then started the car back up and guess what...still no sound. I messed with the sound settings and it's not in mute, volume controls are functioning fine. I know that the Dimension sound system have some kind of amplifier that is powering the speakers.
View 1 RepliesI'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...
View 8 RepliesSo on my new 2.0T Sonata I noticed a brief metallic rattle in the 2K-3K RPM range when you rev the throttle. I was very concerned.
The sales rep said it may be the heat shielding that is coming lose. He was concerned and said to bring it back when Service is open.
I just got back from the dealer: The service manager didn't know what it was but his tech said it was part of the turbo system, it's a 1/4 inch bar (parallel with the bumper) you can plainly see between the firewall and engine. He said what it did but I forgot to take notes.
I listened to another 2.0 Turbo Sonata on the lot and it has the exact same rattle when rev'd.
My vehicle: 2013 Sonata Limited - 4500 mi. When I park on an incline, set the parking brake then release the foot brake, hear a 'creaking' noise from rear. Dealer says "it's normal and nothing can be done" ? I don't think so...
View 6 RepliesWhen you back up slowly from a parking lot or a parked position and start to pull out slowly turning... the car starts making this clicking sound... its not from the steering wheel.. but it feels and sounds like the sound is coming toward the front wheel somewhere...
View 6 RepliesI have 2011 Sonata Ltd. As I cross over 60 mph, I hear a whinning sound from the rear wheels. I have 50K miles on it and is still under warranty. All 4 tyres were recently mounted and balanced by another dealer.
Dealer checked and said it is from tyres, but also said the tyres look good. Rotated the tyres but I am still getting sound from behind. At times it is quite loud.
The 2011 sonata gls won't start - i put key in, turn, lights come on but there is a clicking sound and the car won't start. Is this a battery issue?
View 28 RepliesI have a very intermittent problem when starting my car. Usually it is when it's very hot outside, although not always. Start the car with the AC on, recirc, after about 3-5 seconds its a very loud "slide whistle" type sound (going from lower to higher, pretty high pitched). It only lasts about a second and sounds like something opening and creaking? Brought it to the dealership before, but its so intermittent that I doubt they tried very hard to find it. It probably only happens once or twice a month and will not duplicate if I turn off the car and start it again.
View 35 RepliesI've got a 2011 Sonata GLS with 83k on it.
Last night I was driving and started to hear a repetitive knocking sound. Stopped to determine if it was only when moving but it continued in park.
Checked the oil and apparently there was very little of it.
Don't know how I screwed that up but the mechanic heard the engine for 1 second and said I need a full engine replacement.
So, yeah I am ticked off and need to take care of it.
The VIN qualifies for a replacement under the recall but I don't know how the dealership will feel about the present engine condition.
If that's not an option, where do I even begin to look for a replacement?
2011 2.4 L Sonata. So when I drive the car onto pot holes and rough roads I get some vibration sound from inside the steering. If I hold the steering tight while driving into a pot hole I don't hear the sound. Steering is tight but within the steering there is a part that is vibrating badly and makes cheap sound.
View 3 RepliesThis is my 2011 2.4L Hyundai Sonata with around 78,000 miles(no warranty). For the past two days car wasn't accelerating as it used to and all of a sudden today it started to produce hammering sound. Sounds gets loud with speed. Gears are switching like normal. There is a warning signal also that is attached in the picture below.

I want to know where is the sound coming from? Should i fill any oil? If so what brand and where is the nozzle located.
I was checking the air filter today, when I went to turn off the engine it sounds weird , check in the video on second number 6...
