Sonata NF (2006-10) :: 2 Oil Leaks In Engine Bay
Dec 23, 2011
Taking a look around my 06 LX with 72k miles I noticed a couple of oil leaks.
First one is on the left hand side of the engine what looks like right above the alternator.
Second one is on a hose at the back left hand side of the engine bay, right in front of the firewall..
This car has had the timing belt chain tensioner fix applied to it about 2 years ago.. other than that its basic service at all the major milestones..Its been in Hyundai dealerships for regular oil changes in the last 6 months and they never noted anything..

2006 sonata gl with 4-cyl engine. Car runs/feels fine. Installed HID kit a while ago (with harness) and no problem. Driving home late afternoon (with AC on hi) stopped on red light. Radio was on but NO HID lights on - then momentarily car stalls. Starts back up right a way and NO check engine light. Tried AC- works fine, turn the lights on (HID 35w slim balast), radio on - everything is fine.
My "suspect" is old battery (original!) and I think that for a short moment charging system (alternator) could not keep up/charge battery while car was idling with AC and radio on (hi load).
How long is original battery good for (5-6-...yrs)? Looked earlier at Everstart batteries (or was it Eveready brand?) made by Johnson. I could only find a few batteries but they were sitting on the shelf since last summer (sticker said made 07/2010 !). Are they any good?

I recently got a Sonata from my parents when they moved to Pennsylvania. It's a 2007 with the 2.7 liter engine. It has had low oil for some time, so when I got it (last week) I put more in, up to but not above the full line.
It has had now for just a couple of days a very bad rattle, which is barely audible (but still IS audible) at idle and gets very severe during and after acceleration. It remains for some time even after the gas is no longer being pressed, then subsides a bit. I diagnosed it as knocking, but just today the check engine light came on and the rattle got louder.
I don't have another car to drive and I have class in five hours. Should I drive it or call a cab?

I unplugged the battery and left it over night. Started her up and there was no check engine light. I'm thinking it could be because of the CAI I have installed? Took it to autozone and he said it showing no codes.

I just bought a 2010 Sonata. It runs just fine while running and about half of the time while I'm idling. The other half of the time I can feel my engine sputter. At first it wasn't all that bad but it has gotten worse lately. What could be causing this?

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.

I have a 2006 Hyundai Sonata V6.
The Check Engine light came on days ago. I have tried to re-close the gas cap, it's not it. This morning, I am on my way to bring my daughter to school and maybe 500 feet out of my driveway onto the main road, my car loose it's acceleration power. I pulled over and noticed the ESC light was on. I turned off the engine. Turned it back on. Both lights still on. Rinse...repeat with turning it off and turning it on....this time it worked, ESC light was now off but the Check Engine light was still on. I proceeded back onto the road with no more acceleration problems.

I drive a 2007 Sonata GLS with 54k miles on it. Recently, the engine has lost a lot of power and the fuel economy has gone down quite a bit. (20 mpg in mixed driving)
I replaced the engine oil; air filter & oil filter myself (Full Synthetic & FRAM filters). Engine is sounding and driving lot smoother now. However, the power & acceleration are still pretty bad. MPG is slightly better at 21mpg
I would like to change spark plugs myself and see if that will result in any improvements.
1. What spark plugs do you recommend should I use (there are too many brands out there)
2. How difficult is it to change them.
3. How I can get the car to perform better.

I've Sonata 2006 and it's just fine no problems at all, until this problem comes. When I start the car the engine crank but not start, RMPs is jumping to 4 then into 0.. I checked fuel pump, battery and sparks all are good.

I'm having trouble removing the plastic engine cover on my 2008 Sonata. I removed the two 10mm nuts on top and can raise the front part up, but the rear won't release...so what's holding it on and how do I release the rear side?

Today I experience something new. When I start the car and go on reverse I hear a weird noise coming from the engine. It happened twice today.

When I drive on a hot day the engine overheads; it almost red-lines. This occurs mostly when I drive up long steep hills (I live in the mountains) with the AC on, but even without the AC on very long steep hills (5+ miles) the engine will overheat badly. I can go over a hill and head downhill or flat and things return to normal quickly. I can also drive with the AC on doing 0-80 mph on a flat road and everything is fine all the time.
- Fan is working
- Thermostat has been replaced
- Radiator flushed
- Engine coolant temp sensor replaced
- Heat is working

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).

I just changed out the spark plugs in my 06 Sonata and now the check engine light is on. The car runs fine but I can't find out why the light is on. Is there some reset switch?

Sometimes when I start my car, either after work or in the morning, I can feel the engine shaking. At times it does it after the engine is warm. Its the '06 3.3, I've had the car for 5 days now...

Ok, got a hesitation when the engine is cold, almost feels like a miss. Dealer could not find anything and there are no engine codes. They wanted to replace the plugs with new platinum plugs. I said did you pull any plugs, not that is what the tech said it could be. Could it be the Mass air flow sensor? Or a coil. After a mile or 2 it is fine. I switched to shell premium since dealer told me I had to get a decarbonization from using cheap gas. I used exxon regular and BP regular with a treat of premium every few tanks. But now I am on shell and they said I needed another decarbonization, This is getting rather expensive, I may go back to my local mechanic once the warranty is out. But the hesitation puzzles me.

I got a 2010 sonata, just outside of the warranty with 60,400 miles. as of today these problems arose out of nowhere. the husband had trouble starting the vehicle today and got a check engine light. someone came, jumped it, and was good to go.
Well he comes home on break after 20 mins & goes to start the engine again and it takes 2-3 times to actually start. it's seems to be more difficult the longer it sits; if you turn it off and start it again it's less hesitant. we then replace the old battery that happens to be bad as well, with a relatively new one from my car and have the same problem. no more check engine- but it's still hesitating.
Possible starter problem? is something loose?

Just went and got my check engine light looked at.
This is what code I'm getting P0174
It's also listing ignition misfire condition
Fuel injector problem
and engine mechanical condition.
I don't know if this is listing probable causes of the P0174 or if it's saying those are also problems.
First time dealing with autozone and there check engine light look up.

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.

Few days ago I noticed the noise coming from the engine.
Went to dealership. They removed the oil pan and found metal shavings there .The car has 90,000 miles. They will put a new short block (will be covered by warranty ).
Since they basicaly will disassemble the whole engine, I thought to ask them to replace also drive belts, timing chain tensioner, not sure if the short block comes with the water pump , will ask them . W
