Any very long term reliability issues with it? If not, that'd be great as I frequently get Check Engine lights in my Miata when the gas cap comes loose.

It's not unreliable at all - it merely has a strong enough latch in the system that it can do the job of the gas cap without it. My 2011 has had zero problems with it. Nice little feature.

Yup I love this feature. Edmunds needs to take this car to Thunderhill to see if any gas leaks out under high cornering loads.

Ford has worked out the problems. See how the Mustang's filler is set out from the surrounding area? That prevents junk from collecting, a problem in older versions, like my 2011. There's a cleanout routine on Youtube for when junk prevents the filler flap from fully closing, throwing a code.

I know a few people with Ford models that have the capless fillers. Personally, I think it's a great idea. No possibility of forgetting to put the cap on and having it bounce against your paint as you drive down the road. I work at an auto parts store and we have plenty of people come in wanting a code scan because of a check engine. I've seen quite a few instances when the code refers to a leak in the evaporation system that's simply due to a gas cap that wasn't tightened all the way. With a capless filler design, there's less of a chance of this happening.

It's great until you want to pour in a bottle of Techron or Lucas Oil Upper Cylinder Lubricant. Then you have to find the special funnel that Ford provides for this purpose.
