Gas / Hybrid:
2017 Chrysler Pacifica here with 49000 miles, just out of power train warranty. Wanted to share my story, if if helps others. Same issue, cylinder 3 misfire. Final diagnosis after tear down is that they needed to replace they upper head cylinder. They state there is no warpage, however this is the diagnosis, I assume because they know what is needed to fix this issue. What scares me is that they are only fixing the right upper head, and leaving the original left upper head. I cant really argue much more than I already have about needing both due to a likely manufacturer defect, or a while new engine for that matter.
