Capless Fuel problem solving

Maybe you could put some expandable polyurethane tape around the inside of the gas cap door.

One week of ownership and filled it today when the low fuel warning popped up. The cap-less fill worked fine - it's like not knowing you are pumping gas. I do have it covered with this dust cap to keep things clean and dry:

Does that slip on and off easily? One can't help but wonder how functional it is a -20F in a snow storm for ease of removal, or if it will crack. Nothing seems easy at temps like that.

Yes and seals tightly - -20F - All bets are off...........

Unless they made some change I can't see can't you just buy a 2016 filler pipe and change out that section and put a cap on it.

It only looks like $60 to $70 in parts.

It's a two part filler pipe connected with hose clamps.

While this capless thing might be fine for the average user, it seems to be a real PITA for those that fit outside the average user. There are many reasons that it would not be ideal. Those of us that live rural, there are times when getting gas from the tank for some use is necessary. Also, the amount of crud that can build up under the fill door when living and driving several miles daily on gravel roads. Some of us fill from gas barrels that we have on our property and those nozzles do not always conform exactly to nozzle sizes that are typically at gas stations.

It is ideas like this that get thrust upon vehicle owners, irregardless of OEM brand, that makes owning a newer vehicle seem less and less of a proposition to look forward to. Was recently looking over vehicle offerings from several OEM's, including GM, as a possible replacement for the wife's 2006 Cadillac CTS. All I got was depressed. All vehicles I looked at had some features that were nice, but more that turned me off. I finally gave up. The Caddy is still in pretty good shape, body wise, so I am considering just dropping in a reman engine when this one goes south and keeping the car. I am glad I got my 2015 2500 when I did. Not quite what I would have liked in a pickup (none of the pickup brands are what I consider totally ideal), but it is strong and reliable. At least it had more positive features than negative ones.

2017 Silverado 1500 50K miles showing code P0442. “Small evap leak detected”. Filled up. Saran wrapped filler neck and cleared code. Code was coming in every evap test cycle. Stayed clear until I removed Saran Wrap for next fueling. Obviously a bad capless filler neck. Is there a recall or warranty to cover this? If not does the aftermarket vinyl/rubber dust cap seal enough to pass emissions test? Dealership wanted $130 dollars to “ smoke test” evap system. $1 worth of Saran Wrap was all troubleshooting required.
