The check engine light came on and we brought it to a mechanic to assess the issue. Codes indicated a misfire on Cylinder 3. The mechanic did not state that they observed any physical damage to the head gasket however the engine has coolant in it. The recommended repair is to replace the engine at a cost of $12k.

2017 Chrysler Pacifica LX (~85,000 miles with documented regular maintenance) FEB 2024 vehicle lost acceleration briefly when on highway, almost causing rear-end accident. Coolant and engine temp spiked around 235F (typically 212F-215F range) ambient outside temp (~19F). Took to Chrysler dealer in Walled Lake, MI. Oil leak detected, fixed right head gasket failure (common issue for this engine mechanic says). April 2024 coolant leak detected after coolant reservoir levels became low and smoke of burning coolant was noticed. Coolant leak possibly coming from water pump area after dyed antifreeze inspection. Taking to another Chrysler dealership for service. Complaint is that this is a safety hazard and after further research many owners of this vehicle/engine type complain of this issue, either for the head gasket issue or coolant leaks. (Reference: [XXX] ). I believe this not only a safety hazard but should be filed under a class action lawsuit. This is Chrysler's responsibility to cover when vehicle is outside the 5 year/60K mile warranty when these specific issues occur. Due to the fact that this is a known defect to a significant enough owners and some people either need to pay for costly repair bills or completely need to swap out the engine.

Engine light came on while driving. Had a 303 code for misfire In cylinder 5. Also smelled coolant but didn't see a leak. Brought I. to dealer where they inspected it and said it was a cracked head gasket. Which seems to be a common issue with this vehicle. The repair was done and I'll be bringing it back in tomorrow 2 days after repair for white smoke coming from engine. Also noticed coolant level was lower than when I got it back from shop.

2017 Chrysler Pacifica experiencing engine misfiring / stalling due to blown head gasket and possible engine block cracking at 78000 miles. Happens at idle. Appears to be a common issue and part of a legal settlement in 2023. Have attempted to repair the issue once and vehicle is currently at the dealership service awaiting resolution with independent Arbitrator.

Car has had on going transmission issues with slipping and power loss that dealer was not able to diagnose. The car check engine light came on, and at the dealer the code was for cylinder failure and on inspection at the dealer the left 4th cylinder has failed and the car will need a new engine with only 80,000 miles and proper maintenance. This is available for inspection. Our safety was at risk that the car has had difficulty shifting and has lost power in traffic.

The contact owns a 2017 Chrysler Pacifica. The contact stated while driving approximately 50 MPH, she observed a humming sound coming from the engine compartment. Additionally, the vehicle lost motive power and would not accelerate as intended. The check engine warning light illuminated. The vehicle was taken to the dealer where DTC Code: P00B was retrieved; however, the contact was informed that the engine needed to be taken apart for the vehicle to be fully diagnosed. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 111,000.

Hotter than normal engine heat. Smells very hot even when driving in cabin like some liquid ( maybe Coolant) is burning. Code P0303. Misfire #3 cylinder. Reported issue to dealer several times. Very hot.. paint on hood bubbling. They repaired paint per 100,000 mile 7 year extended warranty. No diagnosis disclosed re known issue with head gaskets on these 3.6 ltr engines. No code until two months after warranty expired. Chrysler mechanic in Santa Barbara told me today that they have to replace gaskets and heads on these 3.6 engines all the time and likely a recall coming soon. Overheating is a safety issue. Leak down test verified bubbling in Coolant reservoir. Mechanic says this issue was highly likely occurring over 1-2 years until it actually triggered engine light and misfire code. Many complaints on Pacifica forums on this exact issue. Have service records re same concerns including from 2022. Thank you

44110 miles. NO leaks, oil change every 2500 miles, all fluids are full and well maintained. Hard shift sometimes while in drive and accelerating. Engine light just came on yesterday with wife and 4 kids in vehicle, then engine light flashing. Pacifica felt sluggish and engine was rough. This happened driving on busy FREEWAY! Quickly pulled over at off ramp. Called tow and Mechanic neighbor pulled trouble code from ODB port using scanner P0306 which is engine misfire in cylinder 6. Car runs like crap and is unsafe to drive. Now need to tow to dealer for very expensive repair, just outside of 5 year warranty.

of all the issues, I want to bring attention to 2 very serious ones. 1) Engine has transmission issue. Auto Shifting of gears give constant jerks and this was never resolved. Chrysler has always avoided this as it's a very expensive fix. Have taken to several different dealerships in 2 different states. (NJ & TX) 2) Coolant leaking. This ends up becoming an engine problem that they don't fix.

I purchased this Chrysler Pacifica from advantage auto sales in new Kensington pa. Making payments obviously but I have had nothing but issues since we got it. Now it-??s up at #1 Cochran and they did a exam and they sent me a video and the transmission is bad, (which when I got the vehicle I been saying something is wrong with the transmission, took it to the garage they kept telling me to take to for now 3rd gear to be grinded out. Head gaskets went in it as well they kept it for over 2 months to not even put parts back together properly, axle is bad. Leaking oil somewhere where still, this fan flapper thingy in the front is bad and been since day 1 there is a bad sensor on it which they told me they fixed and clearly didn-??t. I have had nothing but issues on this vehicle since I got it. It sees more garages than it does outside. I have 4 kids. Making a lot of trips to doctor appointments and such.. so I need a vehicle, they don-??t care. I went to the dealer yesterday and they just told me to take it to another place to get the transmission rebuild or whatever but I feel that isn-??t going to fix it and I-??m just gonna have more issues in the long run. Can you guys help me at all ?! I need something done. My warrenty is up soon and they only cover 8,000 of the tranny and it-??s a 10,000 tranny.

Head gasket blown at 79,000 miles. This is a known issue on this model but Chrysler won-??t admit fault.

My van experienced a cylinder 3 misfire and coolant leak which I now understand is due to a known manufacturing defect in the 2017+ Pacifica engine. I have already spent north of $1700 over multiple trips to my mechanic to replace spark plugs, ignition coils, and coolant flush. Even now, the check engine light continues to come back on when I start the vehicle. This continued malfunction of an engine that overheats and becomes inoperable is indeed a safety defect, especially in a vehicle advertised for families with kids.
