P0455 CEL for EVAP Issue List

Everyone, some of you may not be on my facebook group (join if you haven't! :) )so I thought I would post this here as well. Several of you have had the CEL illuminate with P0455 due to an evaporative emissions problem. This is currently a very common issue, especially those that live in cold climates. I think there's enough of a problem here that it needs to be brought to Hyundai's attention, so I put together a little form for people to fill out that have had the issue. That way we can get a list together as proof that, at the very least, a TSB should be issued for a fix.

Please do not fill out this form if you have not had a CEL for P0455 or do not currently own an Elantra Sport.
