At 63000 miles engine misfire occuered needing to replace the head gasket causing leaking coolant into the combustion chamber causing a misfire. Very concerning considering relevtivly low milleage and potential ongoing engine concerns. Wife and children were driving when check engine light went on, resulting in misfire causing car to shutter and stiring wheel shake. Car is curently being serviced at the dealer. There were no early indicators prior to this incident.

I was driving my Pacifica 2018 on the road when suddenly I heard a beep, I looked at the dashboard, it had a red light indicating that my car is overheated, my kids were panicking, hoping it shouldn't start burning. I couldn't stop on the highway because of passing cars. it was towed in to the dealer, I got a phone call that I need a new engine... I had no prior indications of any problem.

Car engine has stalled a dozen times or so. On one occasion it stalled and would not restart, had to tow to a dealer to repair it and it ended up costing $2700. And when it doesn-??t stall on the road the engine constantly has weird acceleration dips where it almost stalls. This has been a constant problem for me and I purchased the vehicle used with 39000 miles on it. Which is not much mileage so I was not expecting this many problems.

The car battery system has failed over 5x when driving. All of a sudden the car battery lights start coming on & stearing shuts down and car stops. The last time it completely shut down. No power to even run hazard lights. No power to lock the car or rollup the windows. It has been 2 weeks and dealership mechanic can not figure out what is wrong.

2018 Pacifica Wheelchair Accessible Van has on several occasions without warning, decelerated and stalled. Displays Place into Park and restart. Van starts sputtering & decelerates. After pulling over, waiting a few minutes it does start again. We've had the van over a year without any issues until now. We did have it at a dealership for a week. They were unable to find anything wrong with it. Very frustrating as we use this van to transport our disabled daughter. Recently we received notice of Class Action Lawsuit for this problem. Doesn't help me right now.

Vehicle began to idle rough, then the check engine light came on with the code P303 (misfire in cylinder 3). Vehicle diagnosed as having a bad head gasket. This appears to be a VERY common occurrence on this vehicle based on posts made by owners here: https://www.pacificaforums.com/

Van started running slightly rough in the mornings if the engine was cold. CEL eventually came on with a P0304 DTC. I replaced the igntion coils and spark plugs since the van was right at 80,000 miles. Seem to run fine for a day after, then issues came back. Took it to the dealership for more in-depth troubleshooting and repair. They failed to do anything after almost two weeks except that now my van wouldn't start. Took the van to a non-dealership affiliated repair shop and they said the starter had failed, but the engine passed the pressure check of the head. Waited almost another two weeks for a new starter, mechanic got it back together, found some coolant coming out of the exhaust manifold and recommended adding leak stop that there might be a small casting issue with the engine. They added leak stop and returned the van to me stating they think there was a small hole in the engine from casting and that coolant was getting by and causing the misfire. Subsequently, the coolant would then travel to the catalytic converter where it would burn off but caused the cat to be much hotter than normal and that was in-turn frying the starter which is pressed up right next to the cat. The van continued to run rough for a couple days before it finally wouldn't start again and now i'm having to have it towed back to the shop. I suspect the issue may a issue with a warped head or something even worse. A cursory search of both online forums and NHTSA reports that this is not a one off or new issue and only seems to be getting worse and more prolific as the average age of the fleet pushes towards 80-100K+ miles. Modern vehicles should be able to go 150-200k miles before head gasket issues become a serious concern.

The engine overheated while driving and required immediate attention, leaving me and my family stranded on the highway. The original code that tripped the check engine light was for a misfire in Cylinder #3, upon further inspection at the dealership it was concluded that the issue was a blown head gasket, causing the engine to overheat and fail. This was confirmed by the dealer. I have sent the issue to the manufacturer as well. There are a number of these issues in public forums. It is apparently a well known defect.

I have owned van for 1 year and taken it into the shop 6 times for blown head gasket, leaking coolant, over heating due to leaking coolant, and now it needs a new ignition coil and spark plug due to coolant leaking. Check engine light pops on every time and the van notifies me that the engine is over heating. Must pull over on the side of the road to let car cool down. Problem has been confirmed, taken to car dealer at every instance. After issue has been taken to dealer and "fixed" check engine light returns after 4-6 weeks, every time. Paperwork can be provided on request.

Van showed the message "Stop safely the vehicle will shut off" and stopped on the road. It was immobile for close to 30 mins. I was able to start and drive back home. It again stopped on the road on the way to the dealer. I have seen number of complaints on this van on the internet. My van is still with the dealer and they could not fix the problem in the past 15days

Vehicle with 60,850 miles (just out of warranty) had leaky right head gasket. This caused the engine to hesitate where power was needed before starting to move and engine did not run smoothly. This caused unsafe conditions when parallel parking - where quick engine response was needed to get out of the roadway from oncoming traffic. The problem was confirmed by check engine light and repaired by a Chrysler dealer for $3,500. Online forums indicate that there are many drivers who have encountered this same issue with early mileage gasket issues with this particular engine.

I confirmed this issue on chrysler pacifica owners forum. Engine block failure at less than 70K miles. Maintained car per owner's manual recommended schedule. Despite good maintenance, we had the issue first manifest as a single-cylinder misfire. Replaced the spark plug and coil to find that the car wouldn't start. Then found a blown 500 amp fuse at the block above the battery terminal. White smoke from exhaust at restart. Ended up with a diagnosis of block failure / warped head gasket. Confirmed large number of reports on the chrysler pacfica owner forum.

The contact owns a 2018 Chrysler Pacifica. The contact stated that while parking the vehicle in her garage, the gear shifter indicator light was not illuminated while shifting from the drive (D) to park (P) and the vehicle was not able to turn off after pushing the START/STOP button. Additionally, the rear liftgate door was not able to open as needed. Several unknown warning lights were illuminated. The contact's neighbor disconnected the fuel lines and was able to turn off the vehicle; however, the instrument panel light and headlights were not able to be turned off. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 47,000.

Months after a start/stop recall software update, my wife and children were entering the intersection to make a left turn and made a complete stop. The vehicle-??s engine stopped. The oncoming traffic cleared up. My wife proceeded to make the left turn but the vehicle did not respond. The engine did not restart on its own. The D on the shift gear began to flash. The throttle sensor lightning bolt symbol appeared on the dash and there was nothing that would allow the vehicle to shift or restart. The vehicle needed to to be powered off. The traffic light turned red and the car was blocking the intersection for the other traffic. After restarting the vehicle, the turn was completed and ran normally. This occurred 3 more times at a stop light on different occasions. The dealership found a wiring issue associated with the start/stop and the vehicle hood open sensor.

I was driving on the highway at approximately 60mph when the engine suddenly quit and the message "Put vehicle in Park to restart" appeared on the console. I managed to get parked in a precarious position on the wedge between an on ramp and the interstate. Although I was able to shift into Park I was not able to restart the vehicle for some time. During that time I called Chrysler Roadside assistance which could not help with the problem and 911 (because it was so unsafe to remain in place) A policeman came and called for a tow but while waiting, the car finally shut down and restarted. The check engine indicator was still on but I managed to drive to the next exit and get to a safe location. I finally was contacted by Roadside Assistance but they could offer no assistance. I restarted the car. The check engine light was off and I completed my trip without incident. This is the third time this problem has occurred. In the other two incidents the vehicle restarted right away. This is an extremely dangerous behavior, however, and seems to be commonly reported on chrysler forums. I do not know if it is related to the current recall or not. I was under the impression that prior recalls had resolved this problem but see it reported in more current models as well. Chrysler apparently does not understand the cause or have a fix. In most cases, it appears they are unconcerned.
