Any of you guys having these issues, if you're under warranty still, put it back to stock and get it to a dealer asap. Mine started mysteriously misfiring on cold starts about a week ago. Went a day without it happening, then it became every morning and after work as well. Coolant level dropping progressively more, misfiring on cold start, smell of coolant, a little white smoke out of the tail pipes...black and white signs of head gasket issues. Drove perfectly fine all day, it was only symptomatic on cold starts. I saw the writing on the wall and got it into the dealer...currently waiting on them to decide if it needs a new short block or a full long block...
If you don't think it's producing white smoke, set up your phone to record your cold start(s). I didn't think mine smoked either until I watched the video I recorded.
If you're out of warranty...I would personally recommend you stop driving it right now with the hope that it will only be a head gasket job. Not worth the risk if it's on your dime.
@RichBrew has been through this already with the same symptoms as @Cmw458 and I. Don't take this lightly for too long and/or pass it off as carbon build up.
