My Enclave spit gasoline at me twice.
I took it to the dealership, they said nothing is wrong, and they were able to put gas in it.

More Details:
- It probably had around ~3 gallons of gas
- I had driven it a week since putting gas in it, so I know it wasn’t anywhere near full
- I took it to a service station, started putting gas in it, and it spit it out and onto my leg
- I took it to a second service station, just before fueling I noticed liquid gasoline was pooling just behind the ‘flap’ into the tank, and bubbling lightly
- Even just letting the ‘flap’ close would scoop up some of the liquid gasoline and kick it out
- I was unable to add more gasoline to the tank at any point

But the dealership spent a day looking at it, said it throws no error codes, says the solenoid is fine, says they don’t see any problems. I asked them to recheck it and try to find even a speculative explanation, because I’ve never had that happen with any car.

Does anybody have any possible explanations?!
