Gasoline smell after fill up

[shagnat]

On occasions after a fill up, I have a strong odor of gasoline inside the car. No, I didn't over fill or spill any gasoline. Just a regular fill up.

Anyone else?

As in life......it's good to give the hose a little shake (tap, if you will) before you put it away.

There are a fair number of threads on this subject. It has happened to me about 6-8 times since I have owned my 2009 Genesis. Some of the other threads may have some answers, but I just try to not fill it up all the way, which seems to have helped.

No filling it up is a work around. I'd rather solve the problem, but, thanks for letting me know that you've also experienced this issue.

As I said, there are several threads on this issue that may have more info, and possibly discuss a Hyundai fix for it. Problem is that Hyundai has a general policy that dealer must be able to replicate a problem before replacing parts.

Yeah, that's the case with most warranty claims with any manufacturer. If they are unable to reproduce a problem, then it doesn't exist in their minds.

I've done some searching but no fixes are found. I've contacted the dealer to see if this issue is at least on the radar screen.

Well, no, it isn't. Virtually every auto manufacturer suggests letting the pump cut off and then removing the nozzle without trying to top it off.

There is a vacuum line which goes from the top of the tank to just below the filler neck and if fuel is blocking that line you can get fumes inside the trunk and cabin. If you let the fuel pump quit normally the fuel level should still be below that line.

Also, it goes without saying that you should ensure you tighten the gas cap so you hear at least one click.

I have never topped off my tank beyond the auto shutoff, yet I have had fumes more than half a dozen times. I believe that some others have had the same experience. I never experienced this on any other car, so not sure we can blame faulty gas pump shut-off mechanisms. I also am very careful about making sure the gas cap is installed correctly after fill-up.

These days, I look at my gas gauge before fill-up, and try to estimate how much gas I can put in without the pump auto shut-off engaging, in order to avoid the gasoline smell. That means I usually end up with about 1-2 gallons short of full each time, which is not a big deal for me since I don't drive much.

Shag have you had your fuel tank worked on (including fuel tank air filter)? They have to pull the back seat to open the access hatch on top of the tank. If they didn't re-seal the hatch right, it could vent fumes into the back seat.

Yes, I've had the same problem and that is without a top off of the tank. Forget the top off issue. It has happened with 3/4 tank. Took my unit to the dealer twice. Could not replicate. Called Hyundai Customer Service 800-633-5151 and opened a case. They sent out a filed engineer who could not duplicate the issue. I asked them not to test drive the car but the POS drove the car 22 miles during the time they had the vehicle. Please call and complain. Service manager said, well it is the hot weather and you just have to put up with it. BS-How about the last half dozen vehicles I've had in the pat ten years-not one with heavy and overwhelming gas smell. Never had this issue with any other cars I've owned. Something is amiss and Hyundai can't figure it out yet.

Even if they did figure it out, they probably don't want to fix everyone's car.

I have had the problem with 3/4 of a tank also. I think it may have occurred after a sudden stop or sharp curve with high G forces, etc, that may have precipitated the problem. Obviously there is a design flaw in there somewhere, since as you say, never happened on any other car I have owned or driven (and I have driven a lot of rentals).

I don't know about Shag, but I have never had any work done on my car in that area of the car. I have only taken the car into the dealer one time, and that was fairly recently, well after more than half a dozen occurrences of overpowering fuel smell. All the dealer did the one time I took it to them was an oil change and a few TSB's (DOT-4, airbag, etc). I do all my own oil changes, except the one recently done by the dealer (which I had to do over again when I got home because they did not use the oil I supplied for the oil change).

I've never done any really hard cornering so I can't say about what effect that might have, but a few times after driving the vehicle in hot weather for an extended period (doing chores etc) and coming home I noted a very strong overwhelming smell of gas. After having the car parked in the garage all day when my wife gets home from work she comments on how heavy the smell was. A few times after the vehicle was taken to the dealer it happened again but I was not in a position to immediately go to the dealer so they could smell it. That is most likely how the mystery will be solved.

First Off,
other car manufacturers have had and are having the "Gas Smell" issue..
The only time I have had the "Gas Smell" was on my recent Grand Canyon vacation..An older type fuel pump did NOT auto turn Off, spilled a few pints till I pulled the filler.. I washed the paintwork down and then ran the car thro' a carwash..The fuel smell lingered for a few hours..Otherwise no problems..

I suspect (hope) that they have fixed it by now and would not occur on a 2013 like yours, but I don't know for sure.

On my 2009 Genesis, the fuel smell is inside the car only, and quite overwhelming. I have had to open all the windows to avoid being overcome by fumes. It has only happened about 6-8 times on my 2009, but not necessarily right after a gas fill-up (although always seemed to happened when tank was at least 3/4 full). But I try not to even fill up to the point of auto shutoff of the pump anymore, and just put in what I can calculate I need to get to about 7/8 of tank full.

I am relieved (in some respect) that others are having the issue. Hope Hyundai makes a concerted effort to fix it. Seems as if the strongest odor outside the car are in two places-near the gas cap and by the left front fender just behind the left front wheel. That is where I seem to get the strongest smell although inside is very strong too.

As I mentioned, there are old threads on this subject that go back a long time and quite a few have had this happen a least of couple of times. I don't think it is a big deal for most people, since it only happens occasionally, but would be a bit embarrassing if it happened with other people in the car.

Hyundai may have fixed it on new models (I don't really know), but I think it is safe to say that they are not going to fix it on any existing cars unless they can replicate the problem, and even then it is so intermittent that I am not sure they can (or would) even fix it they could replicate it. I guess it may have something to do with fuel air filter. I wonder if the fumes are also in the trunk, which would scare me since that is where the battery is, and I could imagine that a spark could set off an explosion.

You're just bored, right?! I've been filling up gas tanks on more cars than I can count for over 50 years...... do you really think I need a lesson on how to fill a gas tank...... or how NOT to fill a gas tank!

 

[shagnat]

Shag have you had your fuel tank worked on (including fuel tank air filter)? They have to pull the back seat to open the access hatch on top of the tank. If they didn't re-seal the hatch right, it could vent fumes into the back seat.

I bought the car used, but, I'll definitely check with the dealer (bought at the same dealer that sold it new and first owner had all the work done there).
Thanks for the tip!!

Fuel tank air filter clogged or low flow? Other posts on forum seem to say that it does get dirty and needs changing at Hyundai intervals shown. If it is restricted charcoal system will not allow pressure relief when tank is closer to full could be another reason. Fumes build to higher pressures as heated and sloshed around.

Or maybe the tank air filter was changed at some point. And not a good seal which shows up in different conditions (not all the time) of temps and pressures.

I am not saying any of this is definitive. Suggesting another line of troubleshooting.
