While driving on the highway, our car started to make a jerk, like it was having trouble shifting gears, which is weird because we were driving through Kansas and the road was smooth and flat. Then suddenly the car lost power, but did not turn off. Pressing the accelerator did nothing. We turned on the emergency flashers and pulled over to the shoulder, shifted into park and then turned the car off. We waited a few moments then restarted, everything appeared fine. We started to accelerate and merge back into the highway when it started to happen again. This time, our dash reported a message of "shift into p to start." We again pulled over, waited even longer, and restarted again. After about 5 miles, it did it again. After several occurrences of this, we eventually looked to have it towed to the nearest dealership. However, now it also has trouble starting. This is incredibly concerning, losing power going 75mph.

My 2017 Pacifica just passed 96,000 miles and started acting weird. We sent it into the mechanic and they said there is a blown head gasket on cylinder 1. The repair will be between $4,500 and $5,000. Under normal conditions, a head gasket should not be blown on a regularly maintained vehicle with less than 100,000 miles.

I turned on the vehicle cold in the morning and it started shaking violently. The check engine light came on with a code of P0303, which indicates a cylinder 3 misfire. We took the vehicle to the Chrysler dealership in our area and they said there was nothing they could find. The dealership cleared the codes and the check engine light didn't come back on for another week or so. Then the same thing happened again. Cold start, with violent shaking. Check engine light came back on and same engine code P0303.

The van stalls and completely turns off while coming to a stop, while stopped, and while accelerating from a stopped position. I have to wait a few seconds, then push the brake and the ignition switch to restart the van. The van acts as if it's been parked. This has happened 6 times in the last four days.

As soon as I stopped at a light, the entire car shut off on its own. No lights, no engine. It took about 45 seconds for lights to come back on. I was able to restart the car. When restarted, the electronic throttle indicator light was on and the car was jerky to drive. I cut the car back off and on and it drove normally. The engine has cut off 3 other times stopped at red lights, but those times, the lights stayed on. I was able to immediately turn the engine back on. I believe there is a major electrical issue happening. I have taken the car to a dealership and an independent mechanic. No one can find out what is wrong because they couldn-??t mimic the problem.

I purchased 2017 Chrysler Pacifica in 2021, I started having issues my vehicle after my 30 day warranty expired it seemed on and off at times now more noticealbe the START/STOP feature failed to work properly. The vehicle stalled when the brake pedal was released I had to restart the vehicle. The contact disabled the START/STOP feature. Additionally, while driving at night in the rain the vehicle acted up or started to blow hot air from the AC unit at 75 degrees with out the option to change it only way to restart was to turn on and off the vehicle. I also had problems with the coolant being low, and coolant was added. The vehicle was taken to an independent mechanic who informed the contact that the check engine and coolant lights were illuminated. The battery was faulty, and the START/STOP feature was inoperable. A pressure test was performed however, the mechanic was unable to locate a coolant leak. The vehicle was taken to two mechanics EGR cooler valve was cracked and my engine was damaged as well as the pistons. The vehicle had to have the whole engine replaced which was an expensive expense I had to pay out of pocket, the dealer did not cover the damage. The manufacturer was notified of the failure and referred the contact to NHTSA for assistance. The approximate failure mileage was 104, 000 or so. I still do not feel safe using this vehicle it is my family vehicle, please advised. I have invoices but not at the moment I had to replace the engine, the battery, the coolant container, and the radiator for a total amount of about $5000

Blown head gasket

Engine 3.6l non-hybrid has bad head gaskets/heads causing misfire and dangerous potential for vapor lock and engine failure. This is a known issue and there is a recall for the exact same vechile and engine up to 2016. Mine is a 2017 so its not covered in the recall for the exact same condition with the exact same engine. Spoke to manufacturer today they looked at offering some assistance in the price to fix the known issue, unfortunatley I bought the car used (paid over $25,000 in 2018) due to this the manufacturer can not assist in anyway. This is a known issue that is well documneted online by thousands of upset customers. I have no choice but to pay an exorbitant amount to have it fixed before it vapor locks going down the road and hurts my family.

P303 issue but the dealer is asking to replace whole engine.

The van began to run rough in the mornings when I first started up. I initially thought a tire was flat. But all tires were fine. It did this several mornings but then would begin driving smoothly as normal about 2-3 minutes after the drive started. A little less than two weeks later the check engine light came on for the first time. It ran roughly but lasted a little longer; maybe 5 minutes. The check engine light would go off. It did this a couple of times. The third time, the check engine light came on and started blinking. Then maybe 20 minutes into the drive the van began to overheat. I turned on the heat and the gauge went down to normal right away and drove as usual. The check engine light stopped blinking but stayed on. No problems for the rest of the hour-long drive. The next day, the same thing happened while i was on the highway. It started overheating, but the overheating lasted longer and intensified at higher speeds, so I had to drive about 24-35 on an expressway. I took it to a Fiat Chrysler Auto/Mopar Service repair shop immediately. The manager suspected that there was a crack in the cylinder and coolant was leaking into possibly the engine or somewhere else. They said they've seen this same crack, in the same location on many other Chrysler Pacificas. They took pictures (see attached) and sent it to FCA/Mopar. It took several weeks for an FCA/Mopar Inspector to come out. But once they did, they confirmed a crack and the van required a new engine. I'm told this engine is on backorder and it will take months before I can get a new one. I've read many stories online of other people having similar issues. The fact that this engine is on backorder for months is telling. The company Chrysler Customer Care/Mopar/Stellantis has not been helpful in providing useful timelines throughout this repair process. In addition to the above issue, I've also had to replace both main (2x) & aux batteries and experienced problems with sliding doors failing to open.

Since buying our Pacifica it would shift really hard and shake the car. Upon taking it into the dealer they said it was a common problem and there-??s nothing they could do for it. Now, with only 64,000 we have a broken head gasket. There are many complaints of this online right around this mileage and it should definitely be recalled.

Now one week after cylinder 5 being fixed, the Pacifica bas a blown head gasket. Tons of smoke, tons of shaking and jerking.

I have been trying to take care of this urgent safety recall since February 2023. The local dealership (4520 Shelbyville Rd, Louisville, KY 40207) keeps telling me that they don't have a "loaner" care to provide to me while my vehicle is being repaired. I am a single father with 7 year old and primary care giver to 77 year old mother with Alzheimers, I must have a replacement car while mine is being repaired especially since this is the manufacturer responsibility. Please help.

Our 2017 Chrysler Pacifica's check engine light came on. We took it in and the dealer replaced the spark plugs. Two days later the light came back on. They are telling us its a cylinder misfire and cylinder 5 is filling with coolant. They are charging us thousands of dollars to fix this issue. The car is not safe to drive until this is fixed. We have researched and found that this is a very common issue with these vans. Chrysler needs to be held accountable. They could have fixed this issue with a recall instead of waiting for our safety to be compromised and then spending thousands of dollars for the repair.
