Yikes, Just sent in my 2018 Chrysler Pacifica into the shop with a P0305 code. Was hoping for a spark plug or coil issue.... Just received a call saying it will need a teardown... Crossing my fingers for a recall

Any word back from you mechanic on outcome of teardown? I received my new engine at 66k miles from a P0303 code and blown head gasket. I was fortunate the vehicle was still under warranty until 100k miles. I still never received an explanation from dealer or Chrysler on the cause of head gasket to fail. I doubt they will ever say even if they did know.

They called and said they started the teardown and noticed excess fuel in the cylinder. They said it could be a faulty fuel injector. I asked about the head gasket as well amd they said it didn't look to be the cause of the code. They also said it doesn't appear to be from a warped head. I asked them to check further into it as I would like it fixed fully and to not have to revisit this issue in a few months. I will let you know when they get back to me with the final diagnosis!

Almost by definition, a misfire is incomplete combustion, which would result in unburned fuel in that cylinder. Have they taken the head off or just inspect the cylinder via the spark plug hole? If they took the head off, then you should be getting a new head gasket - only the lousiest mechanic would put the head back with an old gasket.

I recently took my 2018 Pacifica Limited with just under 66k miles to dealership for a check engine light code p0303 (cylinder 3 misfire). The car would idle roughly. clearly distinguishable. No other OBDII codes. No overheating or coolant issues. The dealership mechanic diagnosed and determined a blown head gasket and requested to conduct a full engine tear down. I approved and now the dealership is having Mopar inspectors to check engine. Since I bought from a dealership in 2020 as certified pre-owned, it is still under a 7 year or 100k warranty. As anyone had any issues with getting mopar to honor the warranty? The dealership service rep is hinting that mopar sometimes will not and find ways to say the owner has not properly followed the EXACT manufacturers recommended maintenance. For example getting oil changes every 3k miles. I mean with synthetic oils, do you really need them every 3k? Also, it seems the blown head gasket is common for pacificas at such relatively low mileages. Any other owners have similar issues?

Same issue! 62000 cylinder 3 misfire. Trying to figure out what to do!

Get it into the dealer with a level 3 tech asap so they can do a proper diagnostics. You need a dealer with a level 3 tech in order to get anywhere with possible head gasket issues. I've just gone through this process myself for my 2018 and currently waiting for it to finish being repaired.
