Sonata I45 (YF - 2011+) :: Fuel Smell From Engine Bay
Jul 6, 2016
I was one of the many lucky ones to have my engine stall on me, and just had the replacement put in back in April. Drove the car from San Diego to Phoenix, and everything was fine.
A couple of weeks ago, I noticed some gas vapor fumes coming into the car usually during the initial start up, and then the smell would go away.
I read some old threads from 2011 about the pcv hose causing this issue for many owners, so I replaced both the valve and the hose. This hasn't solved the issue, and when i run the vehicle and inspect under the hood, the fume smell is still coming from that vicinity.
Is there some other valve nearby that i should inspect or replace?

My car if left on in park for 3-4 minutes starts to have a heavy smell of something... Is my car running a little rich or is there a more serious underlying problem?
RPM of car idle is 750.
And car doesn't smell like fuel when I'm driving, only if I leave the car running for a while and it sits there does this smell begin to build up.

I own a 2011 Hyundai Sonata GLS with 20k+ miles on it. Purchased it about a week ago & had no issues until about now. About an hour ago, my check engine light came on & air from the driver side right vent started blowing even though the fan is off. What the issue might be? Also, my fuel door constantly pops open by itself. While driving, when I close my doors, and when I close my trunk it always pops open. Is there any way to fix this type of issue?

I was checking my oil the other the other day and it has a pretty strong smell of gas. The car has 2700 miles and still on the original oil. I drive about 20 miles to work one way and don't make a lot of short trips. I checked tho oil when the car was new and didn't notice the smell. Whats going on? Is this normal for a GDI engine? I will take the care in this week to talk to the service manager but wanted to get some input before i went in.

The past few days when I turn my car on and the before the AC comes on (I leave it on Auto) I get a smell like Silicon Caulk coming through the vents. I notice my AC doesn't actually light up until a few minutes on my Auto setting. It is usually 90+ degrees outside and I have the Auto set in the low 60's. After about ten minutes it will finally kick on and blow cold air.

Well I started smelling Gas fumes in the cabin of my 11 GLS. The smell was intermittent for about a month now. Then last weekend it started getting bad. I found it only smelled when pulling fresh air through the HVAC, so it had to be under the hood. Pulled the engine cover to find the foam backing was soaked with gas. Started the car and could see the Hard fuel line dripping.
I saw from other post on the forum that this tube has one time use fitting on both ends and that a special tool is needed to torque the fittings. Dropped it off at the dealer yesterday and they are replacing the line today.
I tell you all this because the Dealer said that their records show my car had the short block replaced at 24000 miles. When replaced they probably didn't torque the line correctly causing it to leak.
The question I have is, Should I be more or less worried about the bottom end of this engine now that I know it has been replaced? The car has 44000 miles on it now.

My 2011 Sonata smells like exhaust inside the cab of the car unless I keep the button pushed for "inside air circulation".
I called the dealer and as it turns out, this is a common problem with this model. A hose has to be replaced on the exhaust system.
I knew I was smelling exhaust and also knew there was a problem with the car/exhaust!

My wife was in the car today, and complained about a strange odor coming from the A/C vents. I would describe it as a slight vinegar/alcohol/sour odor. I think it is from the A/C vents.

I few weeks ago noticed musty smell out of my air vents but didn't mind it thinking it something temporary. Mind you that this only occurs when i have just the fan running without the AC or recycle feature. I opened up the filter and cleaned it out of debris. Looking at the filter it seem like it got wet because of color change that occurs on it, brownish(muddy). I bought the car pre-owned almost 10 months ago, had one service done but unfortunately Hyundai dealer scheduled the service hour before closing down and i think they didn't mind checking the filter, let alone checking tire/brake tread and no car wash.

I have a 2011 Sonata and have issues where my A/C won't cool properly and gives off a funky smell when I'm at a stop. Then it continues cooling when I drive at speeds.
I am going to the dealership for a steering clicking noise as well and was wondering is it worth telling them this problem too or should I go to an independent shop? My car is at 99,000 miles and I know A/C isn't part of powertrain.

Filled up with gas recently and afterward I have a distinct gas smell in the cabin and trunk. I see the 2011 Sonata has an issue with this. Apparently a pcv valve hose problem. The car is a GL. I did not overfill the tank and the cap is on tight. Has the pcv hose issue been fixed with the 2012 model? Are there other possible issues that could cause this? Plan to call the dealer tomorrow.

I bought a 2012 Sonata limited a month ago and have no complaints so far. I have never owned a Hyundai before and just wanted to ask if a burning smell above rear wheels after driving a bit is normal , due to the fact that the car is still technically breaking in ? It has 850 km on it. I can not smell that rubber burning odour when I park outside though. But when I park in my garage and just walk around or try to get something from my trunk I do get the smell. It used to come form both rear wheels and now it seems to be coming from the right one only, just above exhaust system. I checked the rear rims and breaks for temperature and they do not seem to be any hotter than the front ones. I did get undercoat shield protection called Platinum Shield frome the dealer and from what I could see it does not look like that they put anything on the exhaust system itself.

This morning the Fuel Door can't open, after I tried 7-8 times it opened. So I drove the the dealer, but after I arrive there it can open with each push. The car did that fuel door TSB last month.

I was auto crossing yesterday with about half a tank and I noticed my fuel gauge read 40miles to empty after one of my runs. I filled it back up to the top and it still reads almost empty. Im out of warranty so Is there something I can check before taking to the dealer?

For the last 60 miles, my fuel gauge is showing major usage,for every 6 miles it is using 1/10 of gauge.
When I go to fill gas it takes only less than 1/3 gallon of gas then it clicks full.
So I have driven 24 miles and it is showing 4/10 gauge used up.
No smell of gas

I have a 2011 Sonata GLS with ~65k miles. I have an intermittent problem with the cranking, but will not start. It sounds like the fuel pump is "whirring" before start, and this only happens once a week or so. Other times, the car starts fine. The gas tank is ~1/4 full also.
There has been another intermittent issue (not sure if it's related) - with the O2 sensor heating coil. The check engine light comes on for a day or two and goes away wit the O2 heater coil problem. However, I'm not sure a sensor coil problem would cause the car to not start when it's cranking.
Could it be the crank sensor issue? Is that issue known to be sporadic?

I just replaced my OEM battery with a duralast from autozone. The battery had 138,000 miles. Shortly after, the check engine light came on and code says P0106. Map Sensor. Seems like to much of coincidence that this happened. Have read that disconnecting battery cables for 3 hours may do the trick.

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.

My 2011 has just over 27K miles on it. On Saturday the Check Engine light came on. The next time I started the car, it cranked over for about 5 seconds before starting, which is unusual. Then multiple times Sunday and this morning, it seemed to take even longer to crank before starting. This morning, it barely would stay running. And there was a lot of hesitation driving down the road.
I scanned it with my OBD II scanner and got P0087 (Fuel Rail/System Pressure Low). I dropped it off at the dealer this morning and jut got a call that they are replacing the High Pressure Fuel Pump. But they had to special order it overnight and probably won't have it replaced for another day after that.
Is the high pressure fuel pump the device sticking out the top of the valve cover on the back, driver side of the valve cover, with the multiple fuel lines going into/out of it?
