The worst model year for it is 2017.
We had to replace both head gaskets last July with only 70,000 miles on the vehicle. The repair cost was $4,600.00. This August, we started experiencing coolant leaks again. We discovered the cylinder heads are warped now. This was checked last year and it was not the main issue then. It is extremly disappointing that now at 80,000 miles we are looking at another $5000.00+ repair. There needs to be a recall on the engine cylinders and head gasket.

One year ago (114k miles) I started having some rough idle, stumbling, etc. Then a cylinder 5 misfire code appeared. I swapped around coils and injectors, replaced the PCV valve, replaced lower intake manifold, coolant flush. Still no improvement. So I then replaced all the coils, plugs, and bench cleaned and tested all of the fuel injectors and reinstalled them with new o-rings. Misfire code kept returning. On Veteran's Day last year on our way back from a parade it would barely go over 35 mph with the CEL flashing. I limped it straight to the dealership. For context, I have never run the vehicle hot and have kept up on regular maintenance intervals. I gave them a detailed list of everything I did to the vehicle. They had it in the shop and did a compression test. Compression was good on the cylinder head for 1, 3, and 5. However, a leak down test was performed and showed a significant leak in cylinder 5, prompting the need to replace that cylinder head. Luckily, we still had our extended warranty and this $10k job was completely covered. Fast forward to a month ago (126k miles) I was getting a noise from the accessory drive area. After looking closer, I had to replace the serpentine belt. In order to do that I had to remove the lower radiator hoses and drain the coolant. Got everything back together and started it up. The noise I previously heard was louder and more like a chatter. Then a cylinder 4 misfire code appeared. I tore it down, looked at the plugs and coils. All checked out. Did a compression test and compression in all 3 cylinders was good at #2: 155 psi, #4: 151 psi, #6: 153 psi. Ibwent ahead and replaced fuel injector for that cylinder. Vehicle has been running for a few weeks and is still registering misfires for cylinder 4. Everything is pointing towards a cylinder head replacement, which will cost upwards of $10k, just as the previous cylinder head replacement did. This is a far too common problem on these engines.

I experienced a sudden loss of power and steering while driving my vehicle. The screen advised me to pull over because the engine would shut off soon, but I already had lost steering and power. I turned the car off and was able to restart it and drive it 1 mile home, and the check engine light was on. I had it towed to the dealer. After 2 weeks of testing, the dealer reported, “When your vehicle was initially checked in, the following trouble codes were present: 5 BPCM FAULT CODES P1A21-00, P1D43-00, P1C01-00, P1A2A-00, and P1A29-00. We have completed Recall Y40.” The repair tech said they expected the engine to lose power again at some point and I would need to have it towed in again to be repaired then. The repairs made so far are only software updates, no hardware has been repaired because the dealer said the errors didn’t recur after they reset the system. I have elevated the issue with the dealer and am awaiting a response. I am concerned based on the error codes and technician information that my vehicle is still at risk of catching fire at any time or experiencing another catastrophic loss of power if the faulty hardware is not replaced.

The head gasket failed at 89,000 miles. The engine gave P0305 Cylinder 5 misfire codes and would run rough causing difficult to drive in standard traffic flow. There are borescope pictures of coolant in cylinder 5. We stopped using the vehicle until the repair can be completed. This appear to be a WIDESPREAD problem for 2017-2019 Chrysler Pacifica which are numerous on the road and could be hazardous if these vehicles failed on regular roads and highways.

On 7/16/26 vehicle would not start; high-pitched noise heard near engine during no-start diagnosis. Towed to Goldy Chrysler Dodge Jeep Ram, Huntington WV. Per dealer invoice #27136: blown 500-amp main battery fuse found; after jumping past fuse, white smoke from exhaust and no coolant in system, diagnosed as blown head gasket. Repair: both-side head gasket replacement plus fuse assembly. Vehicle in shop 7+ weeks, returned 9/4/26 with new unresolved issue: strong smell of burned electronics and antifreeze in cabin. All failed components available for inspection upon request. Safety risk: head gasket failure/coolant intrusion caused engine hydrolock, a sudden uncommanded loss of engine power that can occur without warning, including while driving in traffic. Burned-electronics smell raises electrical/fire risk; antifreeze odor raises cabin fume exposure and window-fogging visibility concerns. Confirmed by dealer: Yes. Goldy diagnosed and documented the fuse failure, coolant loss, and head gasket failure in writing, and performed the repair. Manufacturer/police/insurance inspection: Not by police or insurance. Spoke by phone with a Chrysler HQ rep 5 times (8/13-9/1/26) who was informed; no confirmed independent physical inspection by manufacturer beyond dealer's own diagnosis. Warning signs: P0304 misfire on cylinder 3 appeared first, progressing to complete no-start with high-pitched noise, prompting the tow-in and hydrolock diagnosis.
NHTSA complaint #11762335 — an unverified report by a vehicle owner.
When driving on freeway the vehicle overheated and engine warning light flashed and had to come to stop at side of freeway. The vehicle had lost its coolant from a rear heater hose connection. The car was towed to dealer and the repair comment was that a part was deformed from mis-assembly (or words to that effect) - rear heater core fitting clip distorted causing hose come of the core. This was an early life failure.

I am writing about a mechanical failure on my 2021 Chrysler Pacifica Hybrid. Recently, I took my vehicle in for 2 recalls associated with this model. Recall #: 66B, pertaining to the rearview camera & 52D, which corresponds to the high voltage battery. Recall #: 52D could not be completed at the certified Chrysler dealership due to the failure of the Electric Coolant Heater, throwing diagnostic trouble code, (P0E15-00). Due to my vehicle being past its warranty period, at the time of service, by 9,190 miles, I had to pay $1356.70 for the Electric Coolant Heater to be replaced, before my No-charge Recall #52D could be completed. While my vehicle is technically past its warranty period by 10,387 miles], I am reaching out because this specific component, the Electric Coolant Heater, is a well-documented failure point across the Pacifica Hybrid community. The breakdown of this heater directly impacts the vehicle's cabin climate control and the proper thermal management of the hybrid battery system, creating a significant inconvenience and safety concern during cold weather. Section 6 of the NHTSA 26V362 manufacturer filing states that the required remedy includes a software flash to track the battery pack's thermal performance. Because the high-voltage coolant heater core regulates that thermal loop, it is functionally impossible to safely execute the software parameter updates while the module is malfunctioning or failing the dealership's "soak test".
NHTSA complaint #11760367 — an unverified report by a vehicle owner.
The contact owns a 2017 Chrysler Pacifica. The contact stated that the check engine warning light was displayed on the instrument panel soon after the vehicle was purchased. An independent mechanic replaced the EVAP purge valve, but after the repair, the power steering assist failed, and several unknown warning lights were illuminated. A mobile mechanic attempted to clear the codes, but the power steering failure persisted. The vehicle was then towed back to the independent mechanic, where a diagnostic test provided several fault codes, including electrical, ABS, brakes, traction control, rack and pinion, and the check engine warning light was displayed. The vehicle remained with the mechanic unrepaired. The dealer and manufacturer were notified of the failure but provided no assistance. The failure mileage was 107,000.

This report is for a 2018 Chrysler Pacifica with 90,100 miles. The check engine light came on in July 2026. It was a cylinder 5 misfire. The spark plugs and ignition coil were replaced. The check engine light came on again about 2 weeks later (cylinder 5 misfire again), was dismissed and reset by the shop, and came on again about 2 weeks later. This time, the shop diagnosed cylinder 5 misfire due to "cylinder 5 is leaking coolant into the cylinders." They quoted $12,000 for engine replacement. Went for 2nd opinion at a Chrysler dealership. They confirmed cylinder 5 misfire due to coolant leaking into cylinder 5. Cylinder 5 had low compression. Tech recommended replacing cylinder head for $6200. My research shows that this issue is common for the Pacificas, so I reached out to both Chrysler and the dealer for goodwill assistance with the repair. It was declined due to the van being older than 2019. I cannot continue to drive it with this issue, due to the safety risk of engine failure while operating.

My 2019 Chrysler Pacifica Touring L Plus is experiencing coolant leaking into a cylinder, diagnosed by. This has rendered the vehicle undrivable. The Pentastar 3.6L V6 engine used in this vehicle has a well-documented pattern of coolant intrusion into cylinders due to head gasket failure across the 2017–2019 Chrysler Pacifica model years, based on extensive owner complaints already on file with NHTSA and reported by consumer advocacy organizations. Despite this known pattern, no recall currently exists covering this specific defect for 2019 model year vehicles. This is a safety concern because coolant intrusion into a cylinder can cause sudden misfires, rough running, loss of power, and potential stalling while driving — creating a hazard in traffic, particularly at highway speeds or during turns/merges. I contacted Chrysler Case Management regarding this issue. The manufacturer has attempted to attribute responsibility to the dealership rather than acknowledging this as a manufacturer defect in the engine design/manufacturing, despite the well-documented pattern across multiple model years of the same engine. I have also not been provided a rental vehicle despite my vehicle being undrivable.
NHTSA complaint #11758412 — an unverified report by a vehicle owner.
Failed head gasket that put vehicle in compromised working condition on the roadway - check engine light flash, poor and inconsistent engine running. First indications were 5-10 seconds of rough idle after startup when sitting overnight, then p0303 check engine code for cylinder three misfire as well as loss of coolant. Independent shop confirmed issue and replaced head gasket. Problem appears to have re-occurred after 2 years and 20000 miles with similar indications. Same shop advised likely engine block or cylinder head defect or damage and would not do any tear down or repair short of engine replacement.

The contact owns a 2018 Chrysler Pacifica. The contact stated that while driving 15 MPH, there was white smoke coming from the front of the vehicle. The check engine warning light was illuminated. A dealer was contacted. The vehicle was taken to a dealer to be diagnosed, and it was determined that coolant was leaking into cylinder #3, and the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the vehicle warranty had expired. The approximate failure mileage was 130,000.
NHTSA complaint #11756330 — an unverified report by a vehicle owner.
As I pulled up to stop, in electric mode, at a stop light, the display screen pulled up a message to pull over safely because the engine would stop soon, within about 10 seconds the screen showed the engine stopped. I was still at the light. I tried restarting the vehicle, moving the shifter from drive to park and back, pressing the park button several times with no success. With cars honking behind me, I got out of the car, told them my car had died and asked them to drive around me. I got back in the car, repeated the actions a few times and the car started in electric mode. I drove home (about 5 miles) without incident. Check engine light was on. I pulled 2 codes U0412 and U029a. I have had the U0412 code a few times before with only the check engine light coming on. It would go away in a day or two (no check engine light and no code). U029a is new.

While driving, the vehicle began to sputter and the check engine light illuminated. A scan at a franchised dealership showed a stored code for a cylinder 4 misfire. Further diagnosis found coolant intrusion into cylinder 4, indicating internal failure of the left cylinder head and/or head gasket, allowing coolant into the combustion chamber. Upon removing the left valve cover and camshafts, the technician found a broken head gasket and a warped left cylinder head. The dealership replaced the left cylinder head, head gasket, cylinder head cover gasket, and oxygen sensor, refilled coolant, and replaced the PCV valve as a maintenance item. After repair, the vehicle was test driven and no further misfire was detected. This failure occurred at approximately 72,000 miles, low mileage for a major internal engine component, shortly after the factory powertrain warranty expired, leaving the owner responsible for the full repair cost. A misfire caused by coolant entering a cylinder can cause sudden, unexpected loss of engine power and rough running while driving, a safety concern in traffic, on highways, or when merging and passing, since reduced power can make it hard to maintain speed or accelerate out of a hazardous situation. Continued driving with undiagnosed coolant intrusion can also cause secondary engine damage, including hydrolock. The failed cylinder head and gasket were not retained by the owner; the dealership performed the repair as part of the invoiced order. The manufacturer has not independently inspected the vehicle beyond the dealership's diagnosis, photographs, and repair documentation, available on request. This appears to be a recurring issue on this engine platform, as similar cylinder head/gasket coolant intrusion failures, with matching misfire codes, have been reported by other owners of similar model-year minivans with the same engine, typically presenting in the 60,000-85,000 mile range, shortly after the factory powertrain warranty expires.

While I was driving to drop my kids to school My Chrysler Pacifica PHEV dashboard chimed, the check engine light made an appearance, and the screen in my gauge cluster showed a large warning message. “Stop Safely, Vehicle Will Shut Off Soon.” I kept my foot in it and guided the Pacifica Hybrid through the off-ramp and into the rest stop’s parking lot And turned off the ignition and engine for 5 minutes and I started the engine and car allowed me to drive back home . The power tram warning got away that evening when I started my engine . The same problem came back again many times since then. I googled it and found that this is very serious problem which may lead fire .i would like to report this issue now.
