)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. Update on P0455 issue 5/2/18:
I have been in contact with a Hyundai Master Technician who is working on getting us a fix for this issue. They have discovered that some of the fuel/vapor lines (plastic ones) for the EVAP system near the fuel tank are collapsing. Completely unheard of, but I've seen photos. There will likely be a recall to replace the hoses, as well as the Purge Control Valve. And a software update could come with it.
I will update this again when I hear more.
