Sonata NF (2006-10) :: 2007 - Both Headlights Suddenly Go Out
Feb 25, 2011
I have a 2007 Hyundia Sonata. Currently have a 7" after-market head unit, four after-market speakers and a sub that is currently not plugged in. I also put HIDs in the low beams. It has about 73,000 miles on it. I bought it when it had 36,000 about a year and a half ago.
The first time I noticed an issue was about 3-4 months ago. Both of my stock headlights went out at the same time. I checked all fuses, nothing blown. Odd right? I thought there might be something going on with the electric but I was like O.K. i guess i'll get new ones, i could use some brighter ones anyways. So I went with Sylvia SilverstarUltra's. These lasted 2-3 months before one went out. I didn't think at the time that this was connected to the previous problem because only one went out and I drive a LOT with my headlights on during the day and SilverStarUltras have a short life span. So I bought an HID kit off ebay (just the ballast and bulb, not really a 'kit'). I installed them on Jan 28th. Today, Feb. 25, they both went out. NOT COOL!
Electronics : Sometimes as I am driving the electronics in the car "de-surge" if you will. Another words, they seem as though they have less power, the interior lights dim, the fan for the heats slows. This happens only for a second and then returns to normal. It has happened a few time. I don't remember the stereo being effected however.
Sub : The sub on my speaker system. A couple of months or so ago I noticed that my sub on my speaker system had stopped working. It was installed late last summer. I investigated and found no potential short, the ground was secure, and no fuses were blown. I didn't even think this could be related to everything else until today, but it kinda seems like it might be.
I was wondering if maybe I had created a short of some type when installing the stereo system. However nothing in the stereo system seems to be effect besides the sub. Which gets it's power directly from the battery, not the stereo system.
I read on another thread about a older Elantra that had this problem and someone mentioned that it could be the regulator in the alternator going bad and intermittently outputting too much voltage. Although I don't know why that would make the fan and lights in the car slow/dim. I'm currently trying to find someone who can lend me a voltmeter.
How I could locate an electrical problem with my stereo install, or elsewhere in my car?

Both of my 2011 Santa Fe's headlamps (high and low) are not working. The fuses seem to be ok (ohm meter checked) and so do the relays (swapped with other relays). When I switch the lights on to the first position, I hear the relay for the 'parking' lights switch on and those lights work. When I move it to the headlight or auto positions, I don't hear the headlight relays click in.
Is there a schematic/parts location/troubleshooting diagram anywhere (they are not on the HMA web site)? Is there a known connector/wiring issue? I just found a diagram for the multifunction switch on steering wheel, with a pin out of the connector, but that's all I have. This will be hard to trace without some idea of where the wires are going.

Recently, I have had 3 instances where my car alarm suddenly goes off. All times, my car was parked in my garage, unlocked. The keys were sitting on the table and had not been touched.
The only thing is that I think the battery in my remote is started to get low I think but I don't really see how that would cause this issue.

I gotta problem with my headlights. they're too low and I tried to raise them with the adjustment screws but they won't move up no matter how long I crank em... Plus the high beams are also aimed low. Does the adjustment screws both the low and high beams?

The low beams on my 2010 Sonata seem dim compared to my other vehicles. I do not want to install HID lamps but would like a recommendation for a brighter lamp.

I have a 2010 sonata GLS which just turned a year old today. About a month or so ago I bought a 8000K HID kit. Its been working fine but the other night i went to leave a friends house and my headlights would not turn on at all. I replaced the fuse and still nothing. All the wiring is fine on the kit and inside the harness and the headlight. I don't know what to do. I have 2500K yellow high beams and I've been driving with them for the last few days but they blind people and i hate driving with them on. This didn't start until the day i took the car to the dealer for an oil change. what should i do?

I have a 2009 Sonata Limited with the Infinity sound system.
Was driving along today, with music and bass quite loud and the front driver door speaker just simply turned off. All other speakers work fine, including the tweeter on the driver side.
Before I take apart the door panel to check for connections (my main suspect), I'd like to have your opinions on this issue. I already broke the tweeter panel when taking it off to replace my broken side mirror, I'd rather skip taking this off again, with the door panel, if I don't have to. But I assume it will be inevitable to get started!

My 2009 Hyundai Sonata's dashboard readings suddenly went "dead" yesterday that is - the fuel gauge read empty, the speedo wasn't registering nor was the tachometer and the led display couldn't be altered? What might be wrong and whether I can do anything to fix it?

Today my transmission suddenly disengaged while slowing down from 3rd to 2nd as if i switched to neutral.Car revved freely when i pressed accelerator. Then suddenly after a second it engaged again and shifted normally. Never had this issue before i racked up 1,29,000 KM on my ride.
I can't see it as "slipping" as there was no change in speed and it revved freely. Also I 'm due for fluid change. What can be the issue?

Last week I smelled something burning when I arrived home. I looked around the car and did not see any smoke. I noticed the other night that I had no headlights (low or hi beam) The fog light work fine. No fuses are out.

Just purchased a 2007 Sonata Limited from an original owner. Love the car so far and generally super-pleased with my purchase. However, I noticed last night, while driving it at night on highway for the first time, that the headlights (low beams) didn't look like they were aligned correctly. I could see a cutoff showing as a shadow and that looked like the lights were partly being obscured on the bottom half. It seemed more prevalent with the driver-side headlight.
I took it to a local dealership service center (rhymes with Bitz) and the service guy claimed that nothing could be done about it. It is just this way. I figure I'll get a second opinion 'cause it sounded like BS, but I wanted to at least ask on here about this.

Installed a HID conversion kit last night and I was wondering how to adjust the headlights. I did use the adjustment knob on the back of the light unit but that only goes up and down. How about left and right?

So i have a 2005 Sonata GLS and it has been giving me issues. A week or so ago, the 'check engine' came on so I took it to the shop to have it fix. Problem fix, no more light popping up. Now two days ago, the car all of a sudden started stalling and hesitating while I was driving. I kept pressing the gas and the car will accelerate to 40 before slowing down to 20 and the acceleration will then drop as well. I had a mechanic look at the issue and he said it was the throttle position sensor. He changed the sensor and its still acting up. He said to buy the carburetor cleaner and it worked fine for a hour until we drove it again. The problem is still not fix.

My problem is on wed I was driving my car,when I suddenly lost acceleration power, after pulling over to the side of the road I turned off the car and restarted it. However I still had the same problem with acceleration. After a while of trying to get the car to start I called a tow truck and got it towed to the dealer. When I got there they told me it was likely and issue with with a sensor on the gas pedal and the engine. At the dealership I started the car to show them the problem however the car drove perfectly and no engine light came on.
They told me it was most like what they said over the phone the sensors. However on xmas eve they called me and left a voicemail saying the rear cat had went out and taken out both rear exhaust manifolds and it would coast $3000 to fix. My question is how can all that happen without the checking engine light coming on in the car and the car showing no problems while i was driving it and how did they miss it when I had took the car in two weeks earlier for regular maintenance and to correct a drive belt issue due to it walking after I purchased a new drive belt and pulley.

Past week I have noticed a flicker on all lighting (head/taillights, interior lights) on my '06 Sonata (4cyl). Seems to be an intermittent problem, as one time in three there is no flicker, and everything seems to be fine.
Yesterday, when pulling into my driveway, I momentarily lost all lighting/radio/fan for what seemed to me a full second and a half before everything "came back on".
I've checked fuses, battery cables (batty is new, 6mos)... Is this alternator related? What else should I be looking at? My Sonata has been bulletproof. No mechanical issues whatsoever....

Is it normal that while driving I can see my headlights wiggling? I have only noticed it on the highway and it is on all types of highway surfaces. I wouldn't doubt it if it was also happening on regular streets as well.
What I mean is that while driving at night on the highway if I look at highway signs or big rigs in front of my car I can see the lights shining from my headlights and they are shaking like crazy.

I have a 2006 Sonata, last night I was driving and when using my high beam headlights they would stay bright and then dim then brighten up again. The battery has not been replaced since I have had this car, but I didn't know if it could be the battery, alternator or maybe the headlights? They work fine on regular beam, no dimming on this setting.

I recently noticed both of my headlights had a little bit of moisture inside the lens. I'm not sure if it had to do with the HID installation. I remembered I had to make holes on the dust cap but I made sure I closed up the holes with electrical tape after I was done.
Recently (couple hours later) I went to check on the headlights, the passenger side lens seems like it evaporated but the driver side lens has a minor streak of moisture at the bottom. I took pix but i cant upload through my phone. I will post them up on Monday. The climate is constantly changing here in NYC because of the fall season.
Could it be the heat from the HID bulb and the humidity from outside?

My pax headlight on my '09 Sonata is significantly shooting left compared to what it was, how to adjust them horizontally? I know how to do vertical but can't find anything for left and right adjustments.

Both the high and low beams for the passenger side on my 06' GLS are not working. Fuses and bulbs are fine.
Is there anything additional I can check that provides electrical power to one side of the headlights?

I have a 2006 Hyundai Sonata that in winter does very strange things, almost ghostly. While driving, headlights flicker on and off, the dash abs and esc warning lights go on, and rpm's shoot up and stay there as if it downshifted by itself. I have to pull off the road and turn the car off.
Further, three different times I shut the car off and then nothing would work, including not being able to start the car. After it sits a while it then seems to reprogram itself and works properly.
I contacted Hyundai, and they only said bring it in and pay to diagnose it. But there appears to be no fix, as many have reported electrical problems for this model on the internet.
