Issue filling up with gas

[santiagoc84]

I had a Passat TDI. It did the same thing at certain Diesel pumps. My Volvo does it at some pumps. The worst car I ever had for this was a Honda Accord. The answer you seek is pretty simple...other cars you have owned and/or rented, had different shaped fill tubes. No rocket science going on here. Slow down your pumping and/or adjust the position of the pump nozzle in your gas fill. Of course you can see if Hyundai will check it out...it is possible that YOUR Genesis has a defect in the tank fill tube and it is bent or crushed...but, I really doubt that, and I do not think I would want someone taking my car apart to check that. It is up to you. It seems to really worry you. Unless you smoking while you are filling up, it is unlikely to be a fire hazzard. And, if you wipe it off, it is unlikely to damage your paint. Keep extra wax on that area. I think you should drive more...worry less.

Thanks for the info on your past experiences with other cars. I just can believe that paying a premium on a Genesis gives you the issues that are not seen on Sonatas and other Hyundais.

I've already started a claim directly with Hyundai corporate... we'll see where this takes me. I wouldn't be pursuing it as much if everyone else was seeing it on all other Genesis...

No issues with my 4.6 in 6 months of use. I use the auto shutoff at full flow every time I fill up except once for a station with the hold-open rack removed.

Perhaps pumps have changed in recent years, but there used to be a little hole towards the end of the nozzle -- this would allow air to pass to the mechanism in the handle. When the air was interrupted (ie: fuel covered the hole), the mechanism would release and fuel would cease to be dispensed.

The only thing I can see causing your problem is fuel is leaking out of the filler tube BEFORE reaching the nozzle. Because modern fuel injected motors require back-pressure, this type of leak would likely trigger a check engine light (similar to leaving your fuel cap off.) If you've not experienced this, it has to be the fuel pump you're using... you're just unlucky.

It's interesting that you mention a check engine light, because I've had two of those occur, both cleared by the dealer. One they did an ECU update.

I have a 4.6 as well. I think it might be time for a visit to the dealer for you...this should definitely not happen.

Has never happened to me. Before checking with the dealer, you may consider trying a different gas station. Could it be that the pump pressure/flow rate at the particular station is a higher than average?

I can't really see how this is a "Genesis" problem, annoying though it is. The automatic shut-off is part of the Gas Pump not the car. Maybe the Genesis fuel filler pipe is so well vented or it does not allow fuel to fill the filler pipe until it is absolutely full. Either way, the sensible thing to do would be to revert to 'manual' pump operation at a lower flow rate when the tank is nearing full.

why don't you read the previous posts. he has said, he treid all other pumps from Orlando to Miami and in between. Where does he go next...? I mean you must go anffight it up buddy. Hyundai must fix it...

Considering that the fuel pump is designed to kick off once it gets the slightest pressure from gas filling the tank, I'd say maybe you're putting the fuel nozzle into the car incorrectly? Instead of trying to jam it down into the car so far, try the opposite and just get the nozzle in a few inches, so it can properly rest agains the bottom of the fuel tank pipe in the car. I've seen this happen before when people push the nozzle in to far and its elbow actually gets propped up in a way that no pressure builds until the gas is overflowing.

Maybe take a video of you pumping gas, and post it for us?

I'm currently waiting for the Hyundai Regional Manager to call me to schedule an appointment. In the mean time I will make sure to get a video and let you guys know how it goes. This is so annoying that even manually filling up without the automatic shut-off it even spills out, granted it's a bit less, but still enough to drip down the paint...

My first reaction was that you were experiencing a problem with a maladjusted gas station pump, but this seems to occur everywhere.

Most cars have a screen located within the filler pipe. This screen not only catches particles (sometimes) but it may act as a "throttle" slowing down flow. Try this for a theory: when fuel reaches a certain level it backs up against the screen causing the gas pump to turn off. If the screen is missing, or broken then I wonder if the gas pump will shut off later. It should be an easy thing to check if you do have a screen.

I have a 4.6 and have never had a problem. I set the flow to the lowest setting and once it shuts off, I don't top off. Have you tried the lowest flow setting?

 

[scottdk]

My Sonata just started doing this intermittently. Damn. Least I don't drive it

 

[realpix]

I've tried pumps from Orlando all the way down to Miami and in between... I see the problem on just about every gas station

I've had a problem on my 1st fill up - gas flow keep shutting off ev ery couple 10ths of a gallon - had an attendant come out and the nozzle had to be held up higher and manually holding the nozzle handle to pump gas.

Haven't had the problem on my 2nd fill up.

Finally, had my appointment with the Hyundai Regional Manager and I demonstrated the issue to him he acknowledged there was a problem (He mentioned it also doesn't happen on his own Genesis sedan).

After two days, the dealership just called me back that they had to replace the fuel cut-off valve. We'll see where this takes us...


Off topic: I asked him about the suspension on the 2010 vs 2009 and he mentioned that there will not be a retro-fit due because it's not just shocks and coils... he said it's much more that changed. He also mentioned that he had looked into it for his own Genesis.

I think it might be a problem with the gas pump. I've only had this happen at one gas station where I have to pull the nozzle out a little to get the gas to flow uninterrupted; everywhere else, it works OK.

Howdy folks--

I have this problem as well; 2011 4.6 sedan. We've had it in for service and the "vent pipe" was replaced--to no avail (in fact, it had to be returned for an additional fix as the new part caused a check-engine light).

Anyone else with this problem? Any updates?

Thanks!

No issues in my 4.6 in over two years and 25,00o miles. I always use the automatic shutoff at full flow. I don't top off, but I do usually run it up to the next .05 or .10 mark.

I had the fueling issue since day one with my car, but have not brought it up with my dealer because I dread the frustation associated with complaints of this nature. If for example, the left rear wheel falls off, it's an issue that a dealer must address. In this case, they're trained to wear one down rather than fixing it.

However, in the absence of a real solution, I find fueling to be tedious and uncomfortable (standing in below-zero weather adding 1/10 of a gallon at a time). On the other hand, if one takes time to fill the tank in small increments, it's possible to add at least 5 gallons more after the nozzle automatically shuts off. In one trip, a full tank took me well over 600 miles. Moreover, I've used different stations and brands from Michigan to Connecticut and had the same problem, so it doesn't seem a function of pumps or nozzles. Is it possible that tanks from one OEM supplier are baffled differently from those supplied by a different vendor?

I used to have this problem with my G35 - the only solution was not to insert the nozzle fully or to rotate it 180 degrees so that the handle was pointing up. It happened more at some gas stations than others.

I know this is an old thread But am having the same problem pump continues to shut off . Costco here in San Diego says this happens all the time with Hyundai being one of the worst . Santiago c84 did the fuel cut off valve fix the problem?? Thanks
