2014 GC Summit code P0302 Cyl Missfire
Hopefully you may be able to help me out with this. I have a 2014 Grand Cherokee Summit with a 3.6l V6 engine that has 2,495 miles on it. I purchased it in May.
About a day ago the check engine/MIL light came on while I was stuck in a traffic jam. I live pretty close to work so most of my driving is in stop & go situations.
About two weeks ago I went to the dealership to get the GC flashed with the latest transmission and ECM versions since the Jeep was shifting in a rough manner. Needless to say, they performed the flashes yet I continue to experience rough shifting at lower speeds (in sport mode and regular mode both with & w/o ECO mode).
I'm not sure if the aforementioned had anything to do with it but just wanted to mention it in case it helps. Point is, I ran an OBC code scan and found two codes. Both of them were P0302 which indicates a misfire on the #2 cylinder. I've read several threads mentioning that this is pretty common on the 2012 MY WK2. In some cases engine head replacements were the only solution.
Being that I have yet to find information regarding this issue in 2014MY Grand Cherokees, I would very much appreciate your input regarding the subject. Should I erase the codes and see if they come back? Or should I take it to the dealership and have them figure it out? Given that the solution seems to be a head replacement which, as others have mentioned, may take anywhere from 2 to 7, I'd also like to know if it would be ok to get through the weekend and turn the car in on monday.
I very much appreciate your help with this issue and will keep you posted regarding any updates.
