I did a search and there's no true answer to what this may be. My gas cap is as tight as it possibly could be. I'm afraid that if I bring it to the dealer under warranty, they will re-flash my computer removing the LET tune. Can't believe the code isn't even listed in the links below. Doesn't make sense.

Does someone finally have an answer before I go to the steelership? I have reset it and then go days before it reappears. At least it doesn't seem to affect the performance.
