Just have to pull the gun out of the tank a bit, if the sensor detects (by smelling) that the density of gas is high enough, the gun jumps.

This happened to me once. I just sort of shoved it (the nozzle) in and out and in and out and that was that. No problems since.

Yep.

This is still happening to me, definitely a venting issue. I’ve found it a bit easier to fill the tank when it’s cooler weather or at night (I’m in Florida), I have to hold the nozzle as far out of the filler neck as possible or it constantly clicks off. Has anyone replaced the charcoal canister? Thanks!?!?

On another forum this solution worked for several people - I have not tried it yet as I just read it this morning - my car has the same problem filling with gas - try this :
Remove the two 16mm bolts on front of the rear seat and lift it. I did not remove it, just pushed it up. Take out the four screws holding the tank cover off, and pull it up. You will see the top of the gas tank valve assy. The big hose is the vent. Give the top a whack and see if it fixes it. Mine worked like a champ.

Roll over valve is stuck in the sealed position trapping air pressure in the tank. Rap on it as suggested. If this happens repeatedly due to being gummed up, keeping a full tank for a while might help cleanse it of what residue might be causing it to stick.

My 2012 had the same problem. Your fix worked. I used a small rubber mallet all around te base a
nd a couple of taps on the tube assembly. Thank you!

Hi, I have a 2012 500 S and I have had the same problem. I had one mechanic look at it once, he said he just took a hose brush too it to see if there was any gunk or anything blocking the passage. Said his brush came out clean, so he didn't charge me anything because he didn't think he did anything. But for about 7 months the problem went away. Now its back again. I have tried pulling back the ring from the nozzle, and going to different gas stations. Still the problem persists. Which the gas station thing doesn't make sense anyway because I usually go to the same station by my house which works when the tank isn't giving me problems, and it doesn't work when it is.
I am going to try and see if I can get someone to just take a brush to it again, because that worked for a bit. but if it doesn't think time I might try some of the other suggestions.

It sounds like his brush bumped the roll-over valve, where the rubber hose attaches to the tank. A permanent fix is to replace the tank.

I had a mechanic tell me about using a plumber's snake to bump the valve on some cars. I guess he wasn't pulling my leg.

I bought a new car and gave my 2012 Fiat Abarth to my Fiance. She told me it was taking forever to fill the tank, must say I thought she was doing something wrong, until I tried it myself...took ~15 minutes to fill the tank, had to dribble it in. Took it to a mechanic, he said the tank would have to be replaced, that it's a known problem with the rollover valve in Chrysler autos.(of course Fiat is Mopar/Chrysler)
Thinking there must be some way to resolve this w/out spending $2K and why would they put a valve inside the tank, that can't be replaced, GRRRR!
Saw another thread where a guy tapped the top of the tank with a rubber mallet, going to give that a try, before doling out $2K for a new tank.

I have never faced such problem

Very strange issue, never happened to me
