Sonata NF (2006-10) :: No Sound From Radio When Engine Running
Oct 2, 2014
I'm facing a bit of a problem on my girlfriends dads 2009 Sonata (Non-Premium sound system). I just installed a Pioneer aftermarket head unit and am getting no sound when the car is started or when its in ACC mode. However, when the ignition is just turned to the "ON" position (first click) the head unit works flawlessly and all 4 speakers output sound. As soon as I turn it to ACC or start the car, there is no sound at all but the head unit still powers up and shows the track playing. I'm really stumped here guys. I've done literally countless head unit installations and I just can't figure this one out, nor have I ever seen this before. I thought the problem might have been a factory amp, but the head unit does not say JBL or Infinity so that leads me to believe it doesn't have a factory amp. Maybe I'm not the pro I though I was lol.
At any rate, just in-case it matters, there is a line out converter attached to the system in order to add a sub/amp to the stock head unit that I installed a few years prior to attempting the aftermarket head unit installation. I don't think that would matter but I may be wrong. I was planning to remove it and route the RCA's to the aftermarket head unit once everything was up and running.

I understand that filling up with gas when the car is running is not recommended. I did it once without realizing that it could cause issues. Now I am trying to determine if that action has anything to do with the CEL being on. The codes are P0442 and P0456. The codes have been cleared several times but the light pops back on after a while, anyway from one day to a week later.
Smoke test did not reveal any issues. My question is this, can filling up with the engine running cause any physical problems with any of the EVAP components? What would be the most likely problem? I plan on buying a new gas cap, since it is cheap. I do not wish to spend a lot fixing this problem.

My 2.4L engine is making a clanking noise while running. When I checked the oil level today, it was low by about 1.5 quarts. There's no check engine light.
Car has 74K miles now. I purchased the car two years ago with 35K miles. I have always performed regular maintenance myself. The car had its oil control valve replaced at 55K miles.

So this has been happening for a few months now. When the hood is closed it sounds like a fan with a bad bearing slowing down. I had the hood open today and turned the car off and it scared me. I've only ever heard it faintly since I have never turned the car off before with the hood open. It's definately ALOT louder with the hood open vs. closed...for obvious reasons... (See attached Video).

Yesterday, it started sounding like this: [URL] ....
Actually, yesterday it didn't sound as bad. Today I sprayed some BELT DRESSING on it, and NOW it sounds like this!

I own a 07 Hyundai Sonata Limited with 31000 miles. It is 20 degrees today. When I start the car up there is this knocking sound from the engine. Once the car warms up the knocking sound only happens when the car is in drive or reverse. When the car is in park or neutral it is fairly quiet. The sounds is still there but not as loud as in drive or reverse. I have done the routine synthetic blend oil changes between 3500-4500 miles.

My 2006 sonata (3.3l) 108k miles has developed a recent problem. The oil light will come on (usually during acceleration) and then go off in a second. i guess you could call it a flicker. I also notice a helicopter sound from the engine. When I rev it up in park I don't hear it. i hear a slight rattler In the alternator area. the serpentine belt is original.
So last week my daughter got the oil changed. I noticed it was leaking oil. I checked fluids and it was fine. I noticed oil on top of the engine, I just thought they spilled some. Continued to leak. checked the oil again and it was approx. 1 3/4 quarts low. The oil light never came on. I suspected the oil filter (its on top of the engine). brought it back to jiffy lube and they said the filter was loose. they gave me a new one and filled up the oil. no ticks or engine noises were noticeable.
So my question is could the oil light be something else (maybe tied to that helicopter sound)?. is an oil light flicker always low oil pressure.

I was driving this morning after doing a brake job (nothing to do with the problem, just anger coming out) made it about 10 kms and noticed when i took my foot off the accelerator, the heater fan powered down a bit, and back up when I gave it gas...noticed a knocking sound from the engine...pulled into a gas station and put it in park. After a hard time idling, it cut out. I started it again and the idle was not good at all. kept cutting out. Got it going and made it home with the same sort of power issue. Tried to start it a couple times and same issue with the idle. Sputtering quite a bit and noticed quite a bit of exhaust coming out. When I backed it out of the garage, I noticed a small puddle of oil.

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...

I recently bought a 2006 Hyundai Sonata 3.3 V6. Had another issue related to the rear wheel, which I fixed. Today, I changed the oil filter on the car (along with the oil). I have heard this engine noise before, but with the cover off it appears a little louder. It’s basically a ‘ticking’ sound.
The engine uses no oil, and has no other leaks. It has some noise on startup for maybe 1-2 seconds (like a loud lifter or something, but it goes away in less than 2 seconds, and at the same time the oil light goes out). I changed the filter today because I was told that a leaky gasket could result in the Filter not retaining oil between starts, causes some minor knock for a few seconds.
But anyway, this other ticking noise seems to be regular, regardless of condition. I have heard some people say that some engine noise is normal for this engine, but how about this?

I have a 2007 Hyundai Sonata 2.4l GLS. Staring to get an little noise from the engine about a few days ago. The noise what can only describe as a whirring sound and while in the cabin it sounds like it's coming from the right side and in the engine area, especially after a cold start and during acceleration. It is not very loud(have to turn stereo off to hear it and it only last for a couple of seconds as far as I know. My car now has about 240,000kms on it, and since the noise is coming from that area I am guessing it's a pulley of some sort. Serpentine belt was changed last year. What this noise is? I was thinking it might be the belt tensioner, probably should have changed it during my belt change.

I notice a light ticking noise coming from the front of the engine. It sounds like it's coming from the puppies and not inside the engine. The dealer says it's normal. Is this normal for these cars. Mine is a 2008 v6 With 80k.

Earlier today on a easy drive (not pushing it) I noticed a slight "whistle-sound" that I haven't noticed before. About then it became VERY sluggish and the Engine Management Light started to flash.
As soon as I could I pulled over and connected my AL619 and it says "to low turbo/supercharger flow".
I didn't notice any smoke or smell, just a serious lack of power (i was doing 30km/h at the top of the hill).
Just tried to locate the leak, but I cant feel it or see it. I guess one would need one of those "smoke generators" to see where the pressure goes out.
So, do I have a broken turbo, or just a blown turbo pipe/tube?

I have been experiencing a slight issue with my 07 Sonata V6 lately. When I am accelerating, most commonly when already at speed around 80 to 90 km/h, I would hear this 2-3 ticks / clicks when I press lightly or moderately on the accelerator pedal. The car would accelerate fine without any further noises. When I release the pedal, the car slows down a bit, and I press on the pedal again, then the same sound re-appears.

Today 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.

When the radio is on AM and the car is running, there is static . When the car is turned off and the radio remains on, the static disappears. We have had the antenna replaced, the radio replaced and all worked for a while but now the static is back. 2006 Buick Rendezvous...

I just purchased a 2008 Sonata Limited and the XM Radio is not working, when you press the button to turn it on it gives you a loading status on the screen and does nothing else. The radio will play on AM, FM, and CD

I've notice it do this probably 4 or 5 times in the last couple days. I turn my brights on and the radio will turn off for a second and turn back on by itself. Its not just the display going blank because the sound goes off also.
I trying to figure out all electrical I have going when this happens. Rear Defrost etc.
I think it went out once without turning the brights on but I can't remember what I was doing that time. Have less than 4k on my warranty.

2.5 SE ... Surely I must be overlooking something, but I cannot seem to have the radio on without the engine running. There doesn't seem to be a key position just for the radio and when the car is turned off e radio goes along with it. Can't find any settings in the in-dash computer on it. How to do this ?

My 2011 Hyundai Sonata Limited dimension radio (no nav or touch screen) is not working the display stopped working with no sound coming from the radio. It was cold one night and i shut the car off ran inside turned it back on and then came back out to start it and no sound then next day it came back on then shut back off. and no turn on 3 months later. I only had the car a year this Feb 2016 & of course they are saying nothing can be done. It'll be one thing if the radio just didn't turn on but my display is completely blank. No light no nothing. What was the result?
