I was told that I needed a new head gasket. It was replaced, and I picked up my car 3 days ago. So far so good. Car started well and has been driving well.
Since my symptoms are identical, I'm assuming that will be the case with mine. How much did they charge you to replace the head gasket? Did you have the dealer do it, or someone else?

Thanks for the follow-up. I'm just sick over this :(

I happened to have gotten a 10 percent off service coupon from the dealership the week before I brought the car in (max. $200 value per the fine print.)
Excellent idea! I pulled my coupons and see which one will benefit me the most. Thanks for letting me know all the details. I feel a bit better overall, although it still sucks!

Sounds identical to my situation, albeit at 5k miles and under warranty. If they're are so many cases like this, not feeling good about the future with this car. Will be exploring lemon laws this weekend...

This same thing happened to T&Cs I think 2011-2014 models and Chrysler gave an extended warranty on the engine on the firewall side up to 130,000 miles with no time frame if I remember correctly. Had something to do with the casting sand not being properly installed/removed causing a production problem. The outcome over time was warped/cracked blocks, warped/cracked heads, head gasket failures, coolant entering the combustion chamber.

Is this happening again on the backside of the engines (firewall side) again?

Am I late to the party?

Our 2018 Pacifica had 82k miles on it when the CEL came on: misfire in cylinder 3. The van drove fine but had a slightly rough idle. I replaced the spark plugs and intake manifold gaskets, swapped the #3 and #5 coils, and checked all fluids. Everything seemed repaired/normal for 1 week, approximately 200 miles. CEL returned, same code: misfire in cylinder 3.

I pulled just the #3 spark plug and found it was fouled with white deposits and burn marks on the insulator, so I replaced it with a new one. I checked the fluids, cleared the code, and crossed my fingers.

The CEL returned immediately, then turned off a couple of days later, then turned back on. So I popped the hood last night, and suddenly... no coolant in the reservoir.

It's been about 3 weeks since this started. We have a backup car (from my inlaws) and a service appointment next Tuesday. We'll see what they say...

Our issue is definitely the left bank, against the firewall. It would be nice if FCA would review these cases and apply the previous warranty extension.

If you find anything out, please reply here and let me know. Dealership has had my van for a week with no information yet other than misfires, which I already knew :(

I have a 2018 Pacifica Limited with 70K miles and it has a blown head gasket. The vehicle is barely 3 YEARS OLD! Until this point this was the best vehicle my wife and I have ever owned. We LOVED it and were constantly showing off the features to friends!

I am just 10K out of warranty (by miles) but called Chrysler Care as I expected this type of issue would be covered with Good Will funds. The rep told me because I am not the original owner, I am not elligible for Good Will discounts. How does that work!?! Why should it matter if I'm not the original owner? Chrysler is still the original manufacturer and something is VERY wrong if this happens to an almost brand new vehicle they produced. I guess they don't want me to ever buy a Chrysler again.

They told me I could try going to the dealer to see if they will offer me a good will repair. If the dealer doesn't, I will make sure I am extremely vocal to everyone about not buying a Chrysler...I will make sure I tell far more people to avoid Chrysler than I told to buy it. I AM SO FRUSTRATED! To make matters worse I was planning to drive this vehicle from California to Utah to see my college kids for Thanksgiving. Now I'm not sure how we're going to get there.

I'd love it if anyone has any suggestions.

My van has been at the dealer for close to 2 weeks with NO help or even a diagnosis. I may have to have it towed to another dealer at this point. I, like you, have loved this van, but at this point, I won't ever buy another or recommend buying one. I've had people who have driven their vehicles without changing the oil or having regular service and don't have a serious issue like a blown head gasket. I'm pissed, to say the least!

This is my exact same story! Took my van in for oil change and a tune up. I have 100,740 miles. After the repairs I keep getting a po305 misfire. It’s been messed up since 11/3. Dealer called today said there is coolant in my cylinder. I could need a new head gasket or engine. I am beyond upset about this situation and at a loss what to do :(

I have a 4-year-old Pacifica brand new off the lot. Now has about 67,000 miles on it, of course, just past the manufacturer’s power train warranty. At the 4-year old mark almost on the nose, without any previous issues, the check engine light came on & the car was running “rough” while in idle. Garage identified “head gasket issue.” We brought it to the dealer & filed a claim with Chrysler in shock this could happen to a 4-year-old car. Dealer has had it for a month now & diagnosed “warped engine block” and “needs new catalytic converter due to warped engine block causing coolant to leak into engine cylinder.” Has this happened to anyone?? It was a brand new minivan purchased at a an authorized Chrysler dealership. I am told $10,000 worth of parts & labor work, with a month backlog on parts. I am lost and angry!!! Any suggestions??
I know it's late in the game and very sorry for what happened but what was your ultimate fix?
