February 5 2024 my check engine light came on and started blinking as I was driving. I then noticed that my car was sputtering. I stopped my car immediately and had it towed to a dealership at that exact point I had just over 64,136 miles on my 2017 Chrysler Pacifica. The following is the work that they performed on my vehicle. Concern verified. Vehicle has an active misfire, check engine light is flashing. Scanned vehicle for codes and found misfire on cylinder 3. Removed coil and swapped to cylinder 1. Spark plug removed and swapped to cylinder 5. Retested. Misfire moved to cylinder 1. Replaced ignition coil and road tested vehicle. After vehicle was warm the misfire on cylinder 3 returned. Swapped fuel injector to cylinder 2. Misfire stayed on cylinder 3. Removed coil and spark plug from cylinder 3 and borescoped cylinder. Found coolant leaking into the cylinder. Recommend replacing cylinder head gasket and checking the cylinder head for warpage. Removed cylinder head and found cylinder head to be warped and needing to be replaced along with the gaskets. Replaced left and right valve cover gaskets, cylinder head, cylinder head gaskets, timing cover gaskets, exhaust manifold gasket, spark plugs, upper and lower intake gaskets. Completed oil change. Fast forward to December 14, 2024 vehicle mileage 74,955 my wife was leaving to go to the farmers market. She called me to inform me that the check engine light came on blinking and the car started sputtering again. The exact same issue happened again. I told her to stop the car immediately and we had it towed to the same car dealership today December 20, 2024 was the first call that I received from the dealership they informed me that cylinder six has failed the compression test and they recommend having the engine replaced. Currently waiting to speak to more people to see what can be done.
