Sonata NF (2006-10) :: Engine Overheated / No Hot Air In Cabin / Leak In AC System?
Jan 31, 2015
Sonata 2007, SE, V6 3.3 engine, 110000m .... I was driving today on a highway and 5 miles from home notice no hot air coming in cabin. Outside temp was 20 degree. Accidentally AC button must been pushed since the light was on. Engine temp gauge was off and few times it jumped from off (as in completely cold engine) to overheated (max top value). Drove back home and let it cool. I can see there is no coolant left. Obvious there is leak somewhere but the only visible spot is on the passenger side, towards the front of the engine compartment - seems like the leak is from the AC coolant hose between the front and the low pressure service port - or the AC pressure transducer.
Antifreeze can be seen under that part, but is clear that it has not come from the overflow reservoir or any main hose. Is there antifreeze flowing on those parts or should I look at somewhere else? Coolant splash seems too high to be from the water pump - definitely seems as leak from above on one of the hoses or the A/C Pressure transducer. Can this be the primary reason or this is just safety due to other (thermostat or other) issue with the cooling system? What can be done?

2008 with 165K. I had the fuel pump replaced then started getting this code. Garage said they did a smoke test could not find any leak. I then replaced this part (CCV #31453-3K500 / picture attached) I still get the code.

For the past couple of days i've had condensation on the windshields during cold mornings and nights and thought something was up. I looked around and found the carpet on the driver's side of my car is damp and there was a puddle of water directly underneath the seat. I've read it might be a clogged AC drain or something like that. Some solutions seem to be either blowing the AC drain underneath the car with compressed air to get rid of a clog, or finding the tube inside the car and properly reconnecting it incase it got dislodged or kinked somehow. Or does this sound like a different problem? Again only the driver's side carpet seems to be wet.

I drove an Avante 09. Recently, my car was breakdown due to engine overheated, as radiator coolant is dry out and noticed there is a hole in in the pipe and hence cause leakage in the system. As the breakdown was happened in johor bahru, I have no choice but towed my car to hyundai msia dealer workshop in JB. However, after they check, they refuse to repair it due to the reason they do not have the spare parts, as my version is 1600cc and msia version is 2000cc.
Thereafter, I towed my car to the workshop in JB, recommend by my friend in JB. After they checking, the said my engine block is made of aluminum, very easy get out of shape when overheated. They say by changing the headset parts will not completely solved the problem, said to completely solve the issue must changed the engine block. To me, by changing the engine block equivalent changing the whole engine, am i correct?
Any bro here facing engine overheated due to dry out of coolant? Can cause such a big issue? In fact I am a bit doubt on their diagnosis. I don't really think the overheat will cause the engine block damage.

So if i turn off the radio and turn the cabin fan on (lowest level) i hear a tick-tick-tick within the dashboard. It seems to be louder than I remember it to be..
Its there with both the a/c on and off, all temp settings. Fan going bad?

Problem: All of a sudden my car has developed an intermittent smoky smell in the cabin (I'm NOT a smoker). There are no check engine lights on and the car is running fine. The smell is not the classic "hot engine block" smell of the car overheating (which it is not according to the gauge). The smell I am getting is a hot smoky smell, doesn't smell like rubber either. No visible smoke in the cabin or the engine compartment.
Smell usually shows up after driving the car for around 2 minutes, but can vary and sometime not show up at all. The only thing that I can comment is a chirping sound from the pulleys that seems to be associated with humidity (power steering, radiator, etc) and the A/C blower intermittently not working (have not had any issues in past 3 months). How I can diagnose this?

So I've been getting that nasty, musky odor in my 2006 Sonata. I just purchased it used last December, so don't know when the cabin air filter was last changed. I had to do this with my Camry not too long ago, so I still have the spray to try on it if the filter isn't too old/dirty. The problem:
When I lowered the glovebox to get to the cabin air filter, one of the tabs was broken off. I figured no big deal. I pressed on the other three and they all broke off. My husband tried to get it out, but no luck. I'm afraid of damaging it if I try to pry it out and even if I succeed, do I have to do that every time I need to get to the filter? Where I would find a new housing?

About month ago, my cabin lights stopped coming on when I open the door. I can turn the lights on, so it is not bulbs. It's a pain to come home at night and not have the lights come on for a few minutes as I get out of the car.

I bought the car with it a bit over 3 months ago, that was the only problem and simply couldn't pass the deal. Even used car dealer didn't know what it was.
You can only hear it when you go over 50-55+ mph and it comes from cabin air filter area.
I already changed cabin air filter, the other day I replaced filter tray as well due to broken clips. Cleaned the whole area real good and still can't get it to stop whining.

I recently acquired a 2014 Sonata Limited 2.4L. Don't know if its me or not but engine noise seems to be excessive in the cabin especially when I am accelerating from a very low speed, almost like something in the engine is loose. Had it at the dealership today for warranty work (seat belt) and recall work and asked the techs to take a listen when the do their inspection. They came back and said that the noise is coming from the electric fuel pump and that it is totally normal. Previous car I had was a 2011 Honda Accord Ex and it seamed quieter.

I have a 2011 Sonata Limited that now has 70k+ miles on it. For the past year I have been having a problem with the car turning off intermittently, it will occur at random times. I have had no issues starting the car whatsoever.
When I go to shut off my car the engine will turn off, but the cabin lights, and radio will stay on. The screen will also tell me to shift to park. Without turning the car fully on, I can shift the gears sometimes and I will shift it from drive to park again, and it still will not fully shut off. Today, it actually took 20 minutes to get it to go off - every time I hit the start/stop button I could hear it click as well, which was a new noise that I hadn't detected.
I have presented this problem to the dealership, but every time I do take it in the issue never seems to occur while there (just my luck) and they say they have "never heard of such an issue" to the point where I feel insane.
All recalls have been taken care of on my car at this point so I am not sure what the issue is, my fear is the switch is going out, but wouldn't I have the same issue starting the car?

Do I buy an engine or sell the car for parts? My son’s car overheated while driving down the hwy due to a radiator leak. After a first and second opinion, two separate mechanics told me the engine has no compression so basically was shot. The car was in good shape with 102k miles and everything worked. Internet surfing has some used engines with 80-100k miles from $800-$1200, some guaranteed some not. Is it better to rebuild the original engine or buy another used one? Labor cost on top of an engine wont be cheap. Are other parts under the hood expected to be replaced too as a result of the engine overheating?

I went to a holiday light show event with friends, where you drive through about a mile of light displays at a few MPH, but there were long lines to wait to even get in, so the car went from freeway driving to being stopped and occasionally creeping forward a bit, then stop and go slow once in the exhibit, all told probably 1-1/2 hours like this. The air temperature was in the mid-20's F. To my great surprise, my heat gauge went to the top of the scale and I got a red dash light. I did not see any coolant steam from under the hood but I found I needed to add to the tank today, it was on the add line.
It certainly looks like the low speed fan never came on. I was looking through the forums and someone said the low speed fan is supposed to be made to run by the engine temperature reaching a certain point, is this a computer function or a mechanical switch? I also understand that A/C operation makes the fan run at high speed. I will probably let the dealer diagnose this, what happened here? Was it a mistake to keep going and allow the engine to stay hot even at idle? One more thing, as soon as I got back on the road, the temperature went right back to normal.

After hitting 100K mile, every single time I fill her up, I smell strong gas smell around my gas cap area. And yesterday I was about to see my friend around 6pm and check what I found. Gas was leaking under the car. I don't know what is happening and I did all my maintain whenever it come.

What the heck? I have not heard of an over heated O2 sensor. I know they have an extra wire in them for a heater element but I have two temp codes indicating the failure and a permanent code as well.
I know its under warranty but what a weird failure. Overheating...Guess Ill be making that appointment at service earlier than I expected.

3 days ago I bought 2006 sonata GL (I4) from a guy. He showed me his service record and he had his oil change right before he sold the car to me. However, I notice a fairly big oil drop on the ground after I drove for a while and parked. I tried three times and it all dropped.
One thing that I noticed was that the oil was dropping from the shield on the bottom of the car. So I looked into the engine and I have noticed bunch oil oil wet spot around the oil filter hole on the shield. I have Wix oil filter currently. Is the leak coming from the filter?

Was told my Sonata has a leak at the Timing Cover Gasket by two different service stations. Took it to the Hyundai Dealership and they said they would need to pull the engine out to fix it and it would take a couple of days. I read on a couple of other posts that people were able to replace the timing cover gasket themselves. So, I don't understand why the Dealership said the engine would need to be pulled, but I'm reading others say they fixed it without pulling the engine. Am I missing something...? I'd rather not have the engine pulled out if it doesn't need to be.

I've got a 2006 Sonata LX, that has been leaking PS fluid for a while, but has gotten quite a bit worse lately. I finally put it up on ramps, and crawled underneath, and from what I can see, I think it's leaking from the pressure hose someplace.
The hose is covered with some type of a silver wrap. I wiped everything down as much as I could with a rag, waited for an hour, then crawled back underneath. There was some new fluid on the hose wrapping right above where it goes into the steering gear box (the driver-side leg of the hose).
Does this sound like it could be the hose? Would it be ok to remove the protective wrap to make sure? it's only wire-tied on to secure it, so I don't see why not.

I have a 07 Sonata and having recurring valve cover leak. First time it happened it leaked onto my alternator and had to get car towed and whole bit. About a year later they discovered it again during routine oil change and had it fixed again. Yesterday during a routine oil change, they discovered a leak again!! I know this is an established problem but how many times can the same problem occur?? I'm passed the warranty (103K).

My son has a 2007 sonata v6, daughter has one too. Both have about 130K miles, and both developed slow coolant drip leaks. I took off both hoses on both cars, cleaned the crud from the housings and replaced with new hoses and clamps. Problems solved in daughter's car, not so in sons car. I note that it looks like the area below the thermostat housing is wet - and thought that was from the crud/hose situation. But he is still losing coolant, even more now that its getting colder at night, and I's sure its not the hose connection anymore.
The car will generally NOT leak when hot, only as/when it cools off. I.e. puddle in the morning situation.
Looking at the diagrams, it looks like that "housing" is really a connection to the crossover pipe, heater hoses, other stuff (throttle body heat) and also contains what looks like a temp sensor.
I suppose any of these are possible, but my first thought was either a leaky temp sensor (or possibly loose) or something more serious like a cracked housing, leaking o-ring, gasket etc.
