Sonata NF (2006-10) :: Oil Leak After Driving When Parked
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?
Sonata NF (2006-10) :: Leak At Timing Cover Gasket
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.

Sonata NF (2006-10) :: Power Steering Hose Leak?
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.
Sonata NF (2006-10) :: 2007 - Valve Cover Leak
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.
Sonata NF (2006-10) :: Engine Overheated / No Hot Air In Cabin / Leak In AC System?
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?
Sonata NF (2006-10) :: Small Leak From Upper Radiator Hose
I smelled antifreeze when walking by my fiances Sonata, so I popped the hood and saw there was a small leak from the upper radiator hose, where it meets the thermostat housing. I adjusted the stock clamp, but the leak was much worse.
I swapped it out for new clamp that you can tighten, and all is well again. But, what I noticed when I had it off was that the metal neck of the housing was really corroded. Only 15,000 on the car, so I was surprised to see that the corrosion on the metal had already built up causing the leak (pushing the hose away from the housing). I scraped and scuffed to get it clean again, but just wanted to give you all the heads up in case you notice a leak in the same area. The antifreeze tested good and is really clean.
Sonata NF (2006-10) :: P0456 Code - Small Evap Leak Detected
My 2007 Sonata continues to throw a P0456 code, small evap leak detected, gas cap is tight, getting ready to check the evap hoses. The question I have is the evap system covered under the emissions warranty at all ?

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.

I have an 06 sonata 2.4l--last week the CEL came on so I took it to my mechanic and he said it was p0455 which is a large vapor leak in fuel assembly. We tried tightening the gas cap and resetting the code with a scanner but it came back on a day or two later. I have never overfilled my tank and i do not smell gas anywhere. the only real symptom (maybe non related)is my speedometer , it works but it is just a little slow to react when increasing or decreasing speed.---my gas mileage seems to be normal.We got under the car and looked around and couldn't notice any obvious tears in any lines -- should i try buying a new gas cap?--I was thinking it may be speed sensor but my mechanic said if it was the speed sensor , my tranny should be shifting funny , my trans shifts fine. I am at a loss and don't want to have to go to dealer with this.

I have a 2006 sonata 3.3 with auto trans I'm having trouble with fluid leaking from the passenger side axle seal. I have already replaced the seal with a Hyundai seal and it is still leaking. Not as bad as before but it leaks onto the exhaust and smells really bad. The transmission is not overfull...
View 2 RepliesSonata NF (2006-10) :: Valve Cover Gasket Leak But Minor As Dirt Stick To It
I'm suspecting a small valve cover gasket leak. I've noticed dirt starting to accumulate near the alternator side of the front valve cover, there is dirt on there stuck to oil, I don't see any wet oil but its so minor the dirt just sticks to it. 107k miles here. Seems to be a common problem. I think Downhiller had a large oil leak, source unknown around his crank pulley area. You wouldn't think a car this young would leak oil. It's not bad, I havn't had to top any off I just like a mildly clean engine.
View 38 RepliesSonata NF (2006-10) :: Sunroof Leak - Water Coming From Rear Left Side Ceiling Handle
My 2006 Sonata GLS 3.3 started dripping water the other day from the ceiling handle. The drain hoses do not appear to be plugged, water runs freely out. I pulled off the headliner around the place of the leak, and I can kind of see a plastic attachment with the drain hose on the corner of the sunroof frame. The water is coming from somewhere from it, but not from the hose attachment.
My question is, Do I have to replace the sunroof frame? Is it difficult to do? Or can I get away epoxying around the leak if it's small enough? In any case, how hard is it to remove the headliner?

I went into my 2011 se this morning and noticed all 4 doors had water stains on the headliner in the exact same spots. Not sure how this happened and how it's all 4 doors in the exact same spot. Another weird thing is, I don't have a sunroof.

Sonata I45 (YF - 2011+) :: Water Leak At Sunroof Area
2011 2.4L Limited leaking at the sunroof area? On a rainy day after my 60,000 mile service I noticed my driver side floor mat was wet. Took it out, vacuumed the water out and asked the dealer to check it at one of my other recall visits. They could not find the source so I took the car to a body shop who confirmed the source of the leak as being in the sunroof area, but are not able to find a solution.
View 8 RepliesSonata I45 (LF 2015+) :: Tire Developed A Slow Leak
I have a 2015 sonata SE with the stock 16 inch kumho summer tires. One of the tires just developed a leak, a slow one, after 5 days psi drops from 34 to 28. I am guessing I ran over a nail? or maybe valve leak? I don't recall driving over a pothole or anything that would otherwise damage the tire or rims.
Now suppose it is a nail, is it dangerous to keep it in there? will it deteriorate the rubber even more? Or is it one of those things i can leave in there, and just keep pumping air every few days?
Just wondering is it worth it to bring it to the tire shop and have the check for where the leak is and have them patch it.
I have 3750 miles on my tires, when should i get it rotated and/or replaced? How does one replace tire since there is a TPMS system? is it easy to do without dealership?
Sonata I45 (YF - 2011+) :: Gas Leak At High Pressure Fuel Pump
I have a gas leak at the connection of the High Pressure Fuel Pump and high pressure fuel pipe. Gas drips and sprays out from the nut area (see pic). The car take a several seconds to turn over to start.
What is the most likely cause? The car is out of warranty, so trying to repair myself without having to replace any expensive parts unnecessarily.
