I noticed the check engine light came on yesterday comming home from work.My neighbor is a somewhat mechanic and has a reader to read codes.It came up with one code.P0455.I looked up the code on the internet and it says "Evap Emission Ctrl Sys Gross Leak Detected".Also, this morning when putting gas in my H3 I had to let it kind of trickle in,and not full pump at full speed,or it would overflow all over the place.Gonna take her to the dealer tomorrow.Anyone have any ideas on what this could be,just a quick heads up before going to the dealer.

 

Interesting.. I'm not a mechanic or anything, but it sounds like that evap canister isn't letting the pressure in the gas tank release, which is causing it to overflow from the gas tank when you try filling it too quickly.
