Do you still have the grill for sale? I live in Dothan al and would probably come get it if you still have it? Also any more pictures if you still have it?

I took my to the dealership and they said mine was a bad gas cap! I had just bought my 4runner and it can on two days later the same thing yours did so I would try the gas cap first. Hope this helps!
