Check Engine light came on in October 2023. Code indicated misfire cylinder #5. Dealer could not reproduce problem in shop. Returned vehicle with instructions to drive until check engine light came back on. 800 miles later light came back on. Dealer reported code was misfire cylinder #5 again on Nov. 22, 2023. Also found coolant in cylinder indicating blown head gasket. Recommended repair was engine replacement as Chrysler did not recommend head gasket repair. Cost $11,500. Engine has 56,000 miles on it. Power train warranty was 5 years/60,000 miles, so just out of warranty for time but not mileage. Problem could result in total engine failure while driving, putting driver and passengers at risk of injury or worse. Problem was confirmed by dealer on November 22, 2023 and vehicle is currently at dealer service center awaiting repair decision. My research shows that there have been many reported failures of this vehicles' engines with the identical symptoms and repair recommendations. Many Owners who opted for head gasket repair often ended up having to have engines replaced anyway. My vehicle has been dealer-maintained on schedule since I purchased it, as I had an oil change and basic maintenance contract on it that expired September 2023. It gave no indication of any problems before the initial check engine light in October. Never overheated or any other warnings that it had a failing engine. A properly maintained engine should not fail at 56,000 miles.

While driving 70 mph on freeway passing a semi the engine shut off. Had steering and braking but no power. Managed to pull over without getting hit. Dash message "put in park, press brake and press start. Major panic attack as we were 200 miles from major town in the desert. Started car drove about 5 miles and it did it again. Dealer claims to never heard of that problem. Since getting home I've not taken vehicle on freeway. Utterly terrifying.

Hey everyone! I hope you're all doing well. I wanted to share an issue I've been facing with my 2017 Chrysler Pacifica, which I bought brand new back in 2017. Unfortunately, I'm currently experiencing a lack of heat while driving, and it turns out that the engine head gasket is blown and leaking coolant. It's quite disappointing to learn that this seems to be a common problem, with an ongoing lawsuit related to it.

Engine overheating, leaking coolant, Engine 3 misfire, apparently it is a common issue. I have two children I drive around every day and almost had an accident when my engine started overheating. Cost of repairs outweighs current value. Check engine light is constantly on because of this. Car shaking when starting up, etc. This is too common of an issue for it not to be recalled at this point. I have had this vehicle less than 1.5 years and I've already replaced the compressor, the spark plugs, cleaned the fuel injector and body, and have had a mechanic run diagnostics on it multiple times.

Had engine issues a few years back around 87,000 and was fixed at Chrysler in Sarasota FL. Rods and other engine parts had to be replaced and engine was running hot. On 11/4/23 our vehicle is again experiencing the same engine issue at 105,000 miles. From what I have read on threads many costumers have expressed similar issues. I have an appointment on 11/7/23 with the local dealership in Knoxville.

I received a P0303 engine misfire code. I have noticed a very slow coolant leak. Thankfully I noticed the leak before the coolant ran out or else the car could have overheated and left me in a very dangerous situation. My mechanic ran a test and confirmed that there is a blown head gasket. My vehicle has ~85,000 miles and from what I have read that is very few miles to be having a head gasket fail.

On or around September 11, 2023, our 2017 Chrysler Pacifica began to stutter and shake upon ignition. On September 27th, the high engine temperature alarm came up. The coolant reservoir was empty. We filled it up and scheduled an oil change and diagnostic. The Check engine line did not come on for the mechanic during the diagnostic and oil change. The oil change was on September 29th. Shortly after the oil change, the Check Engine line came on again, and on October 5th, the high engine temp alarm came on again. The coolant reservoir was empty again. I filled it again, and drove it to another location. Within a matter of hours, the coolant reservoir was empty again. I scheduled a maintenance visit with our local Chrysler Dealership. I told the dealership the Check Engine light was on and that the reservoir for coolant appeared to be leaking and I had filled it up 3 times. I was informed that the Check Engine light is a Cylinder misfire, and that the car may need a tune up. Upon hear this, I asked the service advisor if they had check the reason for the leaking coolant. I was in disbelief that this was not done as per my original comments. After checking on the coolant leak, the dealership noted that there was no external coolant leak. An internal coolant leak is indicative of a leaking or damaged head gasket. The vehicle purchased in 2017 has 66,000 miles on it. This defective component at this low mileage has put my family at risk of a major accident and will continue to do so due to poor design.

Bought the vehicle in 2020 (Second Owner) from a wholesale dealer and owned the vehicle for about 3 years. Bought with only 20K miles and currently has 55K on Odometer. Car one day wouldn't start. Had it towed to first Chrysler dealer and told it was a bad starter. Paid for starter and fuse replacement and told it filled the shop with smoke indicating a bad head gasket probably caused by a warped engine block. Had it towed to a second chrysler for addition opinion/look where they speculated it "dropped" exhaust/intake valve requiring a new engine/engine replacement. This vehicle is essentially a lemon and people are reporting many issues whith the 17-18 Chrysler Pacifica's. It has been in shops for over a month.

I received P258B warning and further diagnosis came to know that C0021-02 and C1252-92 warnings. While applying breaks i am getting hissing noise and break pedal pushes me back where i have to apply lot of pressure to stop the vehicle. This is happening only when i press the pedals hard. I did diagnosis and noticed that the break vaccum pump fuse gone and replaced the same again it blown. Then realized that that the Vaccum pump it self is not working and the same is ordered and replaced. Now the vaccum pump issue is fixed but still the break pedals are hard and getting hissing noise while applying breaks. Now i may need to change the break booster to get this fixed.

Misfire of cylinder 3 as many have reported. Chrysler stating car needs a new engine. Prior owner had warranty work done at 43k miles. At 60k miles, Chrysler diagnoses engine failure and replacement necessary. Chrysler and dealer denying any goodwill despite of history of problems with this vehicle and the Pentastar engine in 2017 Chrysler Pacificas. Engine light and high temp warning bounced on and off while on a highway. Exited to find no coolant, 600 miles after a $2000 tune-up. Added coolant but was losing coolant too. engine light back on. I am out a car, the money I owe on it or a $12k repair.

Continue issue with stop/start system failure that drains batteries to the point of total power loss, even at high rate of speed. An audible ticking sound, engine misfires resulting in bucking and surging, decreased engine performance, hesitation, loss of power. Start/stop system has been investigated by dealership multiple times. Power loss and engine misfire were reported as the result of the start/stop system failure. However it has been a reoccurring problem with continued worsening symptoms. The safety of myself, my passengers and other travelers is at risk due to the unexpected bucking, surging, hesitation and power loss that occurs during traveling. Problem has not been reproduced at service center as it has been -??solved-?? by replacing batteries and not investing further. Vehicle has been inspected by qualified mechanics. Warning lamps have recently alerted but the problem of engine bucking, power loss, surging, hesitancy have preceded the warning lamp. It has been at least 8 months of engine concerns and 2 years of power concerns that were reported to dealership and only 1 month of the warning light indicating a problem.

I'm writing to report a serious incident involving my Chrysler Pacifica with less than 70,000 miles. Recently, the engine light came on with error code P0303, leading to violent vibrations and power loss while I was driving my children to school. This hazardous situation nearly caused a major accident. A diagnostic at the dealer revealed a blown head gasket, raising concerns about the safety and reliability of this vehicle model. I believe this issue might not be isolated and could pose a widespread danger. I'm reporting this incident to the National Highway Traffic Safety Administration (NHTSA) to request an investigation into potential design or manufacturing flaws that could endanger drivers and passengers. Safety must always be the top priority. Therefore, I am taking the initiative to report this incident to the National Highway Traffic Safety Administration (NHTSA) because I believe that it is imperative to investigate the extent of this issue. It is my hope that through such an investigation, we can uncover any potential design or manufacturing flaws that could pose a significant danger to the driving public. Safety should always be the paramount concern when it comes to automobiles, and it is my fervent hope that by reporting this incident, we can prevent similar incidents from occurring and ensure the safety of all drivers and their passengers. I urge you to take this matter seriously and to conduct a thorough examination of the Chrysler Pacifica to determine whether this issue is more widespread than it appears. Lives may well depend on it.

The check engine light came on, upon inspection at our mechanic we discovered our head gasket was blown. Searching for recalls online I found several other owners of Chrystler Pacifica that have the same issue of blown head gasket at relatively low mileage. Contacted Chrystler and there is no current recall for any of those components.
