Hello all - I just filled up my 13 GT500...believe it or not - my fuel door will not shut all the way...it stays open about a quarter of an inch. I brought it to the Ford dealer - three people looked at it including two mechanics...none of them have ever seen this. One said something seems bent. There is no way anything is bent. Car has 16k miles - I'm the only one to put gas in it. Car is still on warranty - but I'd rather research and fix myself. Has anybody here ever heard of this? Thanks
