Hyundai - Sonata :: 2008 - Gas Tank Overflows When Filling
Jan 21, 2011
I have a 2008 Hyundai Sonata that overflows at most gas stations when filling. To fill the tank, I set the pump on autofill and walk away. The pump clicks off and then the car "burps" and gas comes out the filler neck and runs down the outside of the car and out the bottom. It does not do this at one gas station by my house but seems to at all others almost every time. The car is still under warranty (42,000 miles but the issue started at 29,000) and I have brought it to the dealer 3 times. Each time they claim to have found something new wrong and fix. The first time they replaced the fuel filler neck, 2nd time fuel filler neck assembly (and tested at a gas station and it worked), 3rd time the vent valve. Each time I try it and it overflows for me (except at that one gas station). I have never had this issue before with any other car including my wife's current car. I'm truly stumped, but feel that a car should be able to fill up at a gas pump without overflowing.

I have an 04 Elantra GT. My gas gauge is showing full but the car is running out of gas. I try to fill the tank and I get the annoying click and after trying for a few, gas comes up the filler and overflow tube and makes a mess. At the same time, I was getting a P0449 code. I got an evap canister from the junkyard and that seems to have gone away.
Tried diagnosis but dropping the fuel tank to access the lines. When I jack the tank back up into position, you can hear gurgling sounds and as if the gas is coming up the fill tube. I also opened the access panel under the seat to see the pump assembly and when I removed the 8mm bolts, gas came pouring out. There was definitively gas in there. Checked the float on the pump assembly and it moved?
There is also something at the fuel neck at the top. Don't know what it is and if that could also be part of the problem.

I have a 2008 Hyundai Santa Fe. Runs great, except for the last two months, every time I fill it with gas, it tries to stall out when I start it. Once I get it running for a minute or so, it is fine until the next time I fill it with gas. Tried filling it with premium gas a few times to see if that made a difference...it didn't. Took it to my mechanic; he said the car was fine. This only happens at the gas pump and no other time.

Having trouble filling gas tank, the pump nozzle keeps cutting off. Have to fill by dribbling the fuel in until filled. What the problem might be?

So I fill up my 2007 Sonata for the very first time. I'm squeezing the trigger on the pump, it clicks off automatically when it senses it's full, then about a pint of gas backs up out of the tank and onto the floor. Is there some sort of design flaw on the Sonata that causes this to happen? It could have been a problem with the pump, but I don't usually have that happen with my other cars.

I was filling up my tank, as I was running in fumes a few days ago (just 14 miles before death as per trip computer) and to my surprise, when I filled my tank, it only went roughly up to 16 gallons (15.9xx to be precise) before the nozzle kept shutting off. Was the nozzle defective (or was I in a rush for not waiting until the vapors leave the tank?) or the 18.5 gallon tank has a ~2.5 gallon reserve that even the instrument gauge doesn't account for, as it was all the way in the E with the yellow gas pump icon on?

This just gets stranger by the month. I could have sworn when I first got this 2011 Sonata that the console read 341 after filling it up for the first time. I thought it had said that after I filled it the second time (just after Hurricane Sandy - yes, before the long lines - I was lucky) and it read 329. On those occasions the console had read approx 67 & 69 miles to empty. I know I filled it with 87 the second time around. The first time may have been with 89. And when it stopped at 14.x I thought to myself, hmm, didn't it fill to 15.x the first time? Weird. So I went on with my life.
This past weekend it read 50 miles to empty and so I filled it again with 87 (same gas station I should point out). And just like the last time, before this time, it filled with 14.1xx and read 288 miles to empty. It just seems to me that "Miles to Empty" has slowly gone down. On the third filling I believe it may have read 303 to empty.
Is it me? I am imagining things here. Could have that much sludge/dirt/whatever it my tank because of the gas station I visited or the 87 and not 89 that I have been putting in? Oil and filter were changed in mid October and then again in mid March. Thats about to happen again on the 28th but also to have the required NYS Inspection done. What should I say to them if anything? Could I have picked that crappy of a local area gas station?

I have a 09 sonata NF. The gas pump continually clicks off while filling the tank. I saw this issue discussed here before but I cannot find it. Has to do with a vapor canister and valve?

So I have a little weird issue. My car has been sputtering a little when sitting idle at lights and such. But once I fill it up with gas the sputtering is even more noticeable. What this is?

I have a 2009 Sonata GLS 2.4. According to this site, it's NF model. It's been a great car, and I was able to take care of it's simple maintenance(oil, brakes, etc). However, started late last year, I'm getting the CEL. And every time I pump gas, it would burp and overflow even if I pump only 1-2 gallons. So since then, I pump real slow (and it will still burp, but less). So you can imagine how long it takes me to pump 13-14 gallons.
I read the code, and it's coming back as P0449.

After I fill my 6 cyl 2004 Hyundai Sonata (280,000 km), the engines starts, then stalls. I can only get it to work by keeping the accelerator pushed to ensure sufficient rpm's. If I remove my foot from the accelerator, the rpm's drop to zero.With the engine revving, I put the car in drive and 'lurch' away from the pump. After that, everything is fine. It starts up properly … until the next fill. My mechanic is mystified and I am frustrated.

I have 2008 Hyundai Sonata. The TPMS light has been on for months. Not the little round tire low light...this is the actual letters TPMS. I have had issues in the past with the low pressure light coming on with weather temp changes which were quickly remedied by putting air in the tires. After several new tire purchases the low level light would come on when I left the store and as I drove out and drove a little while they would go off and stay off. I have had tire centers break the sensors and have to replace them. After the last one they reset the sensor, however some time later the TPMS letters came on and will not go off. No one can seem to fix it permanently. The Hyundai dealer service center tells me it's a tire center problem.

My Hyundai Sonata 2008 vibrates when driving at 40 km/h. Steering wheel doesn't shake, only car vibrates. And this happens regardless of pressing gas pedal or not. Front wheels are balanced(as the car is front wheel drive) yesterday but no success.

There is a problem in radio of my 2008 Hyundai Sonata. The radio display illuminates but does not display anything. But sometimes it displays ok magically then again problem appears. All the buttons are working and sound is ok.
But, a week ago radio stopped working at all. When i press on/off button, nothing happens. Only once in 2-3 days it works for some hours then again turns off.

My 2008 has the airbag warning light on - the dealer wants to replace the whole passenger seat bottom. They also say as long as the light is on no airbags will work. Is this true and do I have to just cough up the money and replace this?

My 2008 Hyundai Sonata wouldn't start on two separate occasions after I had refilled my tank. The first incident happened a little over a month ago (early August 2011), the starter would crank, and crank, but no signs of life in the engine. Tested the spark plugs, I was getting spark, but the sucker wouldn't start. The car was only at about 55k miles when this problem began.
I had the car towed to the dealership, and they said after 4 long attempts, they got it to start. I took it home, and the next morning I couldn't start it again. Towed it back a second time, and it started right up for them. Drove it back home again, and for a little more than a month, the car ran fine, but things started acting up again.
A few days ago the wife pulled the car out of the garage (fyi: my garage is level) stopped the car on our slanted driveway and when she came back to start it just minutes later, it hesitated, but did turn over. I filled up the tank, parked it in my garage and the very next morning, I could not start my car again.
Called for a tow from AAA, and the driver said "let me try something". Pulled out a hammer, and wacked the bottom of my gas tank 4 or 5 times. The tow guy gets in, tuns the ignition to engage the fuel pump (didn't turn the key all the way), he does this about 4 times, then the very next turn of the key it starts right up. The driver said it sounded like a bad fuel pump.
I drive the car back to the dealership (this is the third time) and talk to the same guy I had dealt with all along. He calls me later in the day to tell me they finally got it to not start and were able to isolate the problem to the fuel pump sensor. They replaced the fuel pump assembly and I was off and running.
To summarize:
*Refilling the tank on two separate occasions seemed to be related to the car not starting the following day.
*Towing the car allowed the car to jostle back & forth, which for some reason would allow the dealer to start it when it arrived.
*Was able to start the car by hitting the fuel tank (just underneath it) with a hammer, turning the key 3/4 of the way on a few times, then turning the key all the way.
*Dealer diagnosed bad fuel pump sensor, and replaced fuel pump assembly.

My CEL came on today, gas level was a little under a quarter tank.
Took it to Advanced on the way home to have them scan it quick, and it threw a fuel pressure regulator code. I stopped in the gas station on the way home and filled it up, and the CEL was gone and hasn't been on since. I'm thinking HPFP, but maybe not? Could it be injectors?

I have a 2003 hyundai Santa Fe that has had a problem for a few years that I can not figure out, nor can the hyundai dealership. (Though they seem to only want to hook it up to a computer, which tells them that nothing is wrong.) After filling up the car with gas, the car will turn over, but will stall immediately. You can press on the gas and it will stay going, but once you take your foot off the gas it stalls. It act like when you used to flood the corroborator. It takes about 4 times of turning over the car and stalling before it runs normally.
It is a GLS 4-cyl automatic AWD.

I have a 2005 Hyundai Santa Fe, about 128,000 miles on it. For the past 5 months or so, the engine simply won't start after filling with gas - and only after filling with gas. I've tried filling partially from near-empty, as well as filling full from halfway or more full...it consistently won't start up after filling with gas.
After turning the ignition, the engine will turn over, but quickly quits. Lately it's had more trouble turning over at all. To get the car moving, I need to actually feed it gas with the pedal, and "simulate" idle. Even after a couple of minutes, if I let off the pedal it dies right away....as if gas just isn't getting to the engine on its own.
In order to get the car moving, I just have to keep feeding it a bit of gas while shifting to drive (and stepping on the brake), then I give more gas and let the brake go almost as if it's manual-transmission....off it goes.
Oddest thing: as soon as that happens; as soon as the car moves forward (even just to get out of the gas station), everything's back to normal. The car idles healthily at the next stop, as if nothing happened.
No check-engine light, no diagnostic codes come up with a scan. Same results on warm or cold days. Most recent maintenance on it was new spark plugs almost a year ago (doesn't seem related).
Of course, the only time it DID fire up normally after filling with gas was when I had the mechanic with me in the car!

I filled my 2010 Prius IV. Every day since, my indicated MPG has gone up about one MPG, with my 40 mile round trip to work.
I had been running around 46-48 MPG indicated this winter. Next day it was up over 50. Yesterday 52, today it is up to 53 mpg and I have used 1/2 tank on 256 miles, which is much better than my winter stats.
