Licensed independent service center diagnosed that I have coolant leaking into cylinder 5 and that the head gasket is compromised and needs to be replaced. My vehicle only has 84k miles. No warning lights illuminated until I started to experience a shudder when starting the vehicle, shaky start and then the check engine light came on with a cylinder 5 misfire code. I noticed coolant was low and topped off. The vehicle has never indicated it was too hot, but I need to refill reservoir each time the vehicle is driven. I no longer feel safe driving my vehicle as a hot engine could cause failure while driving, leave us stranded in a vehicle with small children, or worse cause engine fire, accident, injury or death. I would never expect to have head gasket failure at such low mileage. I should be able to trust that an auto manufacturer can build a car that will last more than 84,000 miles without engine failure. Many people online are experiencing this same issue with large repair bills or engine replacements needed. I sincerely hope that a recall will be issued for this repair as it presents a safety issue.

-service engine light went on 2 weeks ago, intermittently. - escalated when engine began locking/ shuddering while driving and engine light began flashing. - had vehicle towed to the nearby dealership - dealer diagnosed it as a blown head gasket due to manufacturing defects. Dealer offered up that -??they see this issue all the time-?? with the 3.6L Pentastar engine. - dealer quoted $6000 for the repair but forewarned that the other head gaskets would likely fail as well because of the manufacturer defect. Quoted $9500 to replace both - dealer suggested replacing both head gaskets but also refused to confirm integrity of the engine block and all additional cylinders with micrometer measurements and pressure readings. - there is a known and frighteningly frequent breakdown of this engine in the Chrysler Pacifica. - complete engine failure should not be common place for a vehicle with less than 100,000 miles.

Piston Number 3 is misfiring which is the from an error code. Replaced the piston 3 twice and now coolant is leaking into the engine which cause the coolant to leak into the engine. This is a safety risk since the car does not give a warning until there is no more coolant in the car which can cause a fire while driving. The issue was shown twice and confirmed by 2 independent mechanics and the dealership. The vehicle has been inspected and checked out by 2 independent mechanics and the dealership. It first appeared Feb 16 2024 when the check engine light came on and the next Monday the car lost coolant. The car also shook violently when it was started.

The engine overheated and the vehicle became with three children inside on a major New Jersey highway. This vehicle was advertised for families with kids, and appears to have a safety defect. The first sign something was wrong was when the check engine light came on; shortly after the vehicle became inoperable on the highway. We took the vehicle to several different mechanic shops, including the dealership, and we were told the vehicle has a major engine defect, either a blown head gasket or a total engine failure. The vehicle is currently at a Chrysler dealership being examined.

I keep getting a check engine light that reads as cylinder 5 misfire. I have replaced the spark plug and coil pack and it still will read as a cylinder 5 misfire. Often times when we start the van, it acts as if it has engine problems. I know this is very common in 2017-2018 Pacifica's and seems very unsafe. Something is wrong with the engines in those years of Pacifica's. I have had this check engine light read 4 times and 2 mechanics looked at it and replaced some parts to success.

The #5 cylinder keeps having a misfire sometimes causing failure of the vehicle to get up and move when needed in an emergency Situation this being a family van make even putting children in danger at times. After inspection by myself a Mechanic that even taught College Automotive repair, I have also taught Jet engine repair I find this concerning. Is what is happening is the head gasket is leaking coolant into the #5 Cylinder and we all know water will not admit a spark. Rust can be seen on the Valves and top of Piston cylinder upon inspection. This is a well know issue across the United States and Chrysler Dealers and manufacturers, their mechanics, parts and service departments also know this. This is poor workmanship inferior parts. But the most concerning is not being able to get a response out of the vehicle to get out of the way in an emergency situation and that the owners of Chrysler Corporation do not care. With the cost the consumers paid for these Vehicles it should not have to fall on them due to the inferior parts and workmanship of the manufacturing Company. The Average Consumer cannot afford to fix this issue, and some are still paying for their Pacifica's Immediate action should be taken with this problem as many Babies, Children and adult lives are being put at risk. I would recommend to stop driving these vehicles immediately until the problem is resolved. Accident waiting to happen possibly causing bodily harm.

Received message that Start/Stop component was not working. A few weeks later, check engine light came on. Brought to mechanic, was told to replace main and auxiliary battery. Paid to replace those and two days later, got both the start/stop message and the check engine light again. Brought back to mechanic who, upon finding countless other consumers who have had the same issue, found a blown head gasket with coolant leaking into the engine. Our vehicle has only 44k miles on it and is at risk of overheating while driving and the engine may be damaged.
