Same problem! Tired of it! How am I suppose to know when I have a REAL problem? lol
My Check Engine Light was going on, too, even though I'd securely tighten the gas cap after fueling. Even after I had the gas cap replaced, it'd occasionally go on. I just live with it.

No matter what the mechanics do, the light will not stay off. It always point to the gas cap. I've gotten it replaced with a new one and the problem continues.
Worn gas cap had to replace
Light comes all the time even after replacing the gas cap
Check engine light is on and won't go out.

My check engine light comes on every gas tank fuel fill at different levels. I changed my cap and it is still doing it
The gas cap wore out, and I replaced it for about $20.
