The Check Engine light indicated a misfire is cylinder 1 and the car was running roughly. After changing the injector, spark plug and coil wire, the problem continued. The mechanic finally determined there was radiator coolant in the exhaust indicating a failure of the head gasket. A leak in the engine block, and improper combustion can lead to a myriad of safety issues. A check online revealed this to be a common problem in this Chrysler engine in 2017 in the 1-3-5 cylinders with some contributors suggesting an improper casting of the engine block during manufacture. It commonly appears around 60,000-75,000 miles, generally after the power train warranty has expired. My van was at 75,729 miles. The cost to repair the vehicle was $3488.48. The repair was done by my trusted mechanic as I am sure that the Chrysler dealer would be far more expensive. This is due to a manufacturers defect, not normal wear and tear. This expense should not be borne by the consumer.

Our vehicle started to shudder when we started. We took it to the dealership, who initially was unable to identify an issue. They then, a day later, identified that the head gaskets needed replaced. This required a significant repair. Reviewing online, there appear to be hundreds, if not thousands, of similar issues when this type of vehicle reaches approximately 70,000 miles. Our vehicle is a little beyond 70,000 miles. We have also had some other issues, including about 1.5 years ago where the vehicle would randomly turn off while driving. We did take this in for a repair.

Engine Coolant leaks inside the engine Cylinder #5 without warning and cracked the engine block cylinder head #5. This has happened 2 times on this vehicle replacing the engine once. Vehicle has been maintained in accordance with manufacture recommendations.

- Ashland, VA, USA

The vehicle is available for inspection. At an intersection the vehicle abruptly turned off, while the engine was running and in drive. Children were in the vehicle and I was very scared and in shock when it happened. My car just randomly turned off, while I was sitting in the middle of an intersection and the vehicle was in drive (obviously). I was able to turn it back on, but it was very dangerous and could have killed us if a car had come through the [XXX] intersection while we were stuck there. Safety of other drivers on the road at risk, my life and children-??s lives were at risk. Could have caused death had our van been stuck in the middle of this busy intersection a few feet more forward.

- Andalusia, AL, USA

Numerous issues: 1. Multiple misfire codes, check engine 2. Loss of Coolant, no indication of leaks 3. Faulty thermostat. Loss of A/C and heat 4. Bottom of both sliding door panels corroded, with paint loss 5. Uconnect system malfunctioned, not working at all **Repairs have costs thousands already. And based on the other complaints, probably much, much more. Something is obviously wrong here, but Chrysler is NOT doing much about it unfortunately.

We bought the van on 03/31/2022. On 08/31/2023 we went to get into the van, while it was parked outside of our home, and I tried to start it up but it wouldn't start. I had my mechanic look at it and he said it would need a new engine. I"m so glad that it happened in front of my house or else I would have been stranded somewhere with my kids- which would have been very dangerous. There were no symptoms or indicators of the problem before it happened. It happened out of nowhere. Our warranty on the vehicle expired 5 months prior to it breaking down so we haven't taken it to the dealer. We can't afford it. Before it broke down it went to every single service appointment and was up to date on every oil change/ service it needed.

Blown Head Gasket Had vehicle less than 6 months

Intermittently my van will lose power, all dash lights will pop up, active parksense unavailable, service required, blind spot alert temporarily unavailable, service shifter, fcw unavailable service required, service electronic stability control will pop up on the dash and in the message center. Code p0420 has popped up on a reader. Several trips to the dealership purchased at, and they cannot figure out the issues. I have 2 kids, this is a major safety concern. I had it shutdown on a highway 3 weeks ago with my 9 month old in the van. Recall list says everything was repaired, but it seems there needs to be more recalls. These vans are not safe. Recall them all. Chrysler is going to end up with a lawsuit. I think this is a major defect on the electrical and computer systems. When driving the van it will show I'm doing 70 but really 35mph. The van will rough idle. Again these are all intermittent issues that happen all at once. It seems like the van will reset itself once it's sat overnight. We just bought the van in May 2024 and this started a few weeks later. Very frustrating. The dealership won't buy it back, they can't figure out what the issue is. I

Purchased 2017 Pacifica Limited in [XXX] from Carmax. 38K miles. Purchased Carmax 100K warranty. Within 90 day Carmax dealer repair warranty, Misfire cylinder 3 check engine light came on. Carmax replaced coil, injector etc. Cleared check engine light. June 24 Misfire cylinder 5 check engine light came on. Vehicle never over heated. Took the vehicle to independent repair shop that performs MaxCare warranty work. Diagnosis: Blown head gaskets. 950/? in coolant when tested. 3 week parts B/O. That would indicate many problems. Chrysler Pacifica Forums have hundreds of blown head gasket entries for years 2017-18. The blown head gaskets were causing rough starts, rough idling, and stalls. Additionally, I don't know why this has not been addressed as a safety issue. When this started occurring, my wife would have to hit the START button 2-3-4 times to get it to start and then it ran rough for a few minutes. Some times stall. The Start/Stop feature is affected when the engine does not rapidly start when the pedal is pushed. This is a big safety issue when on the road and in traffic.

Minivan was performing normally, then at a signal light after 14 min of driving on the hwy, the car stalled at a major intersection. Multiple attempts were made to restart but gear selector was locked in drive. The knob would not turn (locked). Multiple Error messages were displayed on central gauges and tow truck had to be called, since car was blocking freeway lane crossing. The car did restart eventually but gear selector still locked and minivan is not operational.

I have researched this and it seems to be a problem that is very common to the Pacificas. Some examples can be found here, but there are hundreds of reports of this across the Internet. [XXX] The problem is twofold. 1. The plastic oil cooler that Chrysler uses on these vehicles is substandard and will fail. Typically this happens just outside of warranty. These parts were made to fail which induces a very expensive repair. 2. There is a very common issue with the head gaskets on these vans. So much so, that when I had one of them replaced on my van the service advisor suggested I do them both because he said the other one would fail soon. He said it happens all the time on these vans. I spent almost $4000 to have one replaced, there is no way I could afford to have more done. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
