After a couple days in the shop and some diagnostics, they are ordering me a new head for replacement. (Fingers crossed)

Not sure if applicable, but I got a notice some time ago about a warranty extension for similar possible issues. Again, not sure if relevant to this specific issue or for others who come across this post. Here's a pic of main letter details about the warranty.

I never received that notice but I remember seeing it. Pretty sure they won't do anything unless there is a CEL. I'll have to wait a bit I guess and maybe make an appointment in a few weeks.

No doubt. :crazyeyes: Glad you at least knew of the extension, though your still under the 100k for now.

Sounds like you just used the key method?

The built in key option only shows current codes, if there's a stored code and the problem isn't currently happening it will take a few drive cycles to go away. Any code reader will give you the stored code, if you don't care to find out what the code was then disconnect battery, wait 15 and it should clear. If it returns get it looked at.

My advice would be to have someone pull the code and clear it, then you know what caused it.

More thank likely, you have a leak at your EVAP canister. More times than not, at the connection where the little white box goes into the big black one. A new gasket or some RTV here may be all you need.

Thanks I pulled the code with a buddies reader and sure enough it was P0456 Evap purge system small leak guess it's time to look for some sealant. Thanks again..

Resurrecting an old thread here. It seems like everyone that has had this problem was under 20k miles. Mine popped up a couple of months ago and, if I remember correctly, it pulled cylinder 4 misfire and multiple cylinder misfires. I have 42k miles and am wondering if this will be covered under the power train warranty? It seems like it is the same problem as everyone else's as I have an early 2012 (bought in Oct 2011). I am taking it in next friday so my fingers are crossed that it will be covered.

Should be covered. They extended all the warranties on the engines do to that problem.

Good to know. Maybe I can sleep better tonight. Definitely don't have the cash to throw down on new heads. Hopefully the wait time isn't 2 months like WOL and the others experienced.
