from another user here at FTE:
I have noticed the same thing lately on our early 2010. My wife is the daily driver of it, and she assures me that she hasn't been spilling gas out when filling. And I don't see any stain evidence of it, either.

After she parks it in the garage after a fill-up, it stinks up the garage for hours. After that, it doesn't smell. I was thinking that if a seal on the top of the gizmo wasn't sealing, why doesn't the gas smell continue day after day? I don't have an answer for that. I have the shop manual set, I'll have to see if they have anything on the capless filler.

Other than if there is a recall, I too will be the one to fix it, if anybody does.

 

I think there is that flag inside the spout that is the cause of this.


Is it dirty or not closing with a snap after fillup?

 

Let me know what you find out!

 

We have had that happen once on our 2012, there was some road crap keeping it from sealing properly. It took all of 10 seconds to fix. You can use the funnel in the rear storage panel to pop the latch, or if that is missing, the fat end of a 1/2" drive extension will pop it as well. A couple quick wipes and you are done. Also if your wife may not be spilling gas per se, but the trickle that is in all gas nozzles can be going into the drain, and if the drain is clogged, it will be there till it evaporates.
