Well, I FINALLY had the filler neck replaced and I've filled it with gas once since (because heaven forbid my ****** dealership put gas in it and test to make sure they actually resolved the issue) and I had no issues! The service slip I received said they found that the filler neck was damaged. I didn't squeeze the pump full force because I was nervous about it doing it again. Next time I will fill it as normal though and if it still has no issues, I'll consider it solved (although I do think it is). So yes, turns out I do know how to put gas in my car afterall and it was not user error as some had made it out to be.
Now I just have to get the blown door speaker fixed and possibly the clock (doesn't keep time). I'll be going to another dealer though because mine (Faulkner Hyundai) absolutely sucks.
