Mike, i am getting a check engine light, and the engineers at the service centre pointed out that both the air mass and purge valve have failed. were so matter of fact about it and trying to lecture me about lifespan of parts! Was not convinced, and you all prove my point.
I do not know anything about the purge valve. It is not something I have had an issue on with my cars. The MAF on the other hand is a different story. Since you have a 2011 model, it does not make sense for the MAF to fail so soon. Best of luck resolving the issue. You might want to also consider getting your own OBDII scanner. If nothing else, it will give you some idea of what is going on before heading into the repair shop.
