general problems of the 2019 Chrysler Pacifica - part 1

My 2019 Chrysler Pacifica touring l plus is experiencing coolant leaking into a cylinder, diagnosed by. This has rendered the vehicle undrivable. The pentastar 3. 6l v6 engine used in this vehicle has a well-documented pattern of coolant intrusion into cylinders due to head gasket failure across the 2017–2019 Chrysler Pacifica model years, based on extensive owner complaints already on file with NHTSA and reported by consumer advocacy organizations. Despite this known pattern, no recall currently exists covering this specific defect for 2019 model year vehicles. This is a safety concern because coolant intrusion into a cylinder can cause sudden misfires, rough running, loss of power, and potential stalling while driving — creating a hazard in traffic, particularly at highway speeds or during turns/merges. I contacted Chrysler case management regarding this issue. The manufacturer has attempted to attribute responsibility to the dealership rather than acknowledging this as a manufacturer defect in the engine design/manufacturing, despite the well-documented pattern across multiple model years of the same engine. I have also not been provided a rental vehicle despite my vehicle being undrivable.

As I pulled up to stop, in electric mode, at a stop light, the display screen pulled up a message to pull over safely because the engine would stop soon, within about 10 seconds the screen showed the engine stopped. I was still at the light. I tried restarting the vehicle, moving the shifter from drive to park and back, pressing the park button several times with no success. With cars honking behind me, I got out of the car, told them my car had died and asked them to drive around me. I got back in the car, repeated the actions a few times and the car started in electric mode. I drove home (about 5 miles) without incident. Check engine light was on. I pulled 2 codes u0412 and u029a. I have had the u0412 code a few times before with only the check engine light coming on. It would go away in a day or two (no check engine light and no code). U029a is new.

My 2019 Chrysler Pacifica experienced repeated electrical/network communication failures. The first sign was erratic dashboard behavior and a check-engine light in our resort parking lot. We drove to pep boys, where it was evaluated and we were told it was okay to drive. We then drove to chick-fil-a (. 4 miles from pep boys). While stopped in the drive-thru in drive with my foot on the brake, the vehicle began dinging, the engine revved, and multiple warning lights/messages appeared, including the check-engine light, red electronic throttle control warning, “blind spot alert temporarily unavailable,” “service trans stop safely shut off engine to engage park,” and “stop/start not ready. ” after shutting it off, it would not reliably restart, and when it did, I could not shift it to move. The vehicle returned to pep boys, where dtcs u0001 (can c bus) and u0401 (implausible data received from ecm/pcm) were documented. It then went to a Chrysler dealership in florida. They evaluated it and told us it checked out and was okay to drive. After leaving that dealership, the problem returned while my family and I were traveling at highway speed. The vehicle malfunctioned and began losing acceleration. I exited the highway. When I stopped at a stop sign, the vehicle died. It restarted but again would not shift. Eventually we were able to reach a nearby gas station. The problem continued intermittently as we tried to get home. Because we could not predict when it would happen again, we determined it was unsafe and had it towed. A Chrysler dealership in georgia then documented numerous loss-of-communication codes and performed a pcm software update. The vehicle passed testing and was released, but the problem returned again after we returned to ohio. The vehicle was ultimately towed to a Chrysler dealership in ohio. The communication faults became active during diagnosis, and the dealer replaced both can-c and can-I splice-block connectors. The problem has not recurred since.

On 7/16/26 vehicle would not start; high-pitched noise heard near engine during no-start diagnosis. Towed to goldy Chrysler Dodge Jeep ram, huntington wv. Per dealer invoice #27136: blown 500-amp main battery fuse found; after jumping past fuse, white smoke from exhaust and no coolant in system, diagnosed as blown head gasket. Repair: both-side head gasket replacement plus fuse assembly. Vehicle in shop 7+ weeks, returned 9/4/26 with new unresolved issue: strong smell of burned electronics and antifreeze in cabin. All failed components available for inspection upon request. Safety risk: head gasket failure/coolant intrusion caused engine hydrolock, a sudden uncommanded loss of engine power that can occur without warning, including while driving in traffic. Burned-electronics smell raises electrical/fire risk; antifreeze odor raises cabin fume exposure and window-fogging visibility concerns. Confirmed by dealer: yes. Goldy diagnosed and documented the fuse failure, coolant loss, and head gasket failure in writing, and performed the repair. Manufacturer/police/insurance inspection: not by police or insurance. Spoke by phone with a Chrysler hq rep 5 times (8/13-9/1/26) who was informed; no confirmed independent physical inspection by manufacturer beyond dealer's own diagnosis. Warning signs: p0304 misfire on cylinder 3 appeared first, progressing to complete no-start with high-pitched noise, prompting the tow-in and hydrolock diagnosis.

A misfire code came up. Had plugs done. . Didn’t solve problem now blowing white smoke burning antifreeze. Head gaskets bad. We just bought this 2019 7 months ago. And it only had 68,000 miles on it now 71000 miles on it. We thought we would get the newer better vehicle and having engine problem in a car that we paid 22000 dollars for. Going to be an expensive fix on a problem that shouldn’t be occurring on a car with that mileage.

The vehicle intermittently displays a "stop safely – vehicle will shut off soon" warning message accompanied by a turtle icon while driving, most often at highway speeds above approximately 50 mph. There is no consistent pattern or condition that triggers the warning. When the warning appears, I must immediately attempt to pull off the roadway because the vehicle indicates it will shut down. This creates a significant safety hazard, especially on interstate highways or roads without a safe shoulder. If the vehicle is turned off and restarted, the warning message disappears, but the check engine light remains illuminated. After the next ignition cycle, the check engine light also disappears, leaving no visible indication of the problem. The issue began occurring approximately once per year but has become progressively more frequent. It now occurs almost daily. During a recent 300-mile trip, the warning appeared four separate times. It also commonly occurs twice during a 60-mile drive. The increasing frequency has made the vehicle unreliable and unsafe to operate on highways. The vehicle has been taken to an authorized Chrysler dealership. However, the dealer stated they cannot diagnose or repair the problem unless the warning is actively displayed when the vehicle arrives. Because the warning clears after restarting the vehicle, the dealer has been unable or unwilling to identify the cause or perform a repair. I also contacted Chrysler customer service. I was informed that because there is no recall related to this issue, they could only refer me back to the dealership for diagnosis under any applicable warranty coverage. This defect poses a serious safety risk because the vehicle may lose propulsion while traveling at highway speeds, requiring an emergency maneuver to reach the shoulder while surrounded by fast-moving traffic. I am concerned that this could result in a rear-end collision or other serious crash if the warning occurs where there is no safe place.

While driving the car is unable to switch gears from d to l gear and has no power to accerlerate up hill.

The vehicle has no power going up hills or accelerating and just stops and doesn't move. To get the car to move again you have to turn the car off and back on. Even if you put the car in l it can still just go back in regular drive on its own an cut out with no acceleration.

Bad engine at 67,000 miles for a blown head gasket. Service records up to date,.

This has been ever since I got my van. Sometime when I drive my lights come on and it goes into limp mode. Most of the time. When I start my van my lights will turn on. I have to turn my car off . Then start again to get my van riding correctly. The other day I was making a u-turn and my engine stalled and I was almost hit by a truck.

We bought our brand-new Chrysler van in 2019. On [xxx] the oil filter housing needed to be replaced due to cheap manufacturing parts. It cost us $918. 78. In October of 2025, we were experiencing some shaking in our van. Upon investigation, it was diagnosed with a blown head gasket. The repair was estimated at $3000 - $4000. The mileage on our van was a little over 93,000 miles. We were meticulous with the maintenance of our van. This, according to Chrysler Pacifica owner online forums, is not uncommon. There is a general outrage at the obvious manufacturing error. Is there any class action lawsuit ongoing? is there any recourse available? Chrysler should pay out due to their shoddy work.

The contact owns a 2019 Chrysler Pacifica. The contact stated that the message “engine would shutoff soon” was displayed. The start/stop, engine, forward collision avoidance, and 4wd warning lights were illuminated. The contact stated that the power steering functionality had become inoperable. The vehicle had stalled on several occasions. The contact related the failure to NHTSA campaign number: 19v348000 (electrical system). The contact called the local dealer, but the vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic who scanned the vehicle and determined there was a code that “voltage-too-high” was displayed. The manufacturer was not notified of the failure. The failure mileage was approximately 129,000.

While driving light came on that car was hot. Immediately pulled over and had the van towed. Was told the head gasket was blown which damaged the engine. Engine now needs to be replaced. Cheapest estimate has been $9,000 at a dealership, van isn’t even paid off yet. My 5 children were in the car when this happened I was afraid the vehicle was going to stop in the middle of the rd. No other warnings or anything. Also when we first purchased van was idle and then go silent like it’s supposed to we have noticed it doesn’t even get quiet anymore. Very disappointed family of 7 with no way to have our van repaired.

While stopped at a red light my van alerted me that the start/stop feature was not working, turned itself off and put the van in park causing much confusion and my almost getting reended as I was unsure what to do.

There was a battery safety recall (72b) letter sent to me for potential fire danger. On the letter, in bold, "a vehicle fire can result in increased risk of occupant injury and/or injury to persons outside the vehicle as well as property damage" 3/25 - 3/29 - 72b recall work at autonation dealership completed since the recall repair, my “service engine” light will intermittently turn on/off. 5/30 - mile high hybrid diagnostic code - u0412 “invalid data received from battery energy control module” 6/12 - 6/18 - at autonation dealership. U0412 - only software upgrade completed 7/1 - 7/8 at autonation dealership - p0d57. They suggested it's a charger issues and to only use mopar charger 7/24- o'malley diagnostic code - u0412 - have only been using mopar charger. (not a charger issue) waiting to hear back from Chrysler on path forward. I want answers to get this hybrid battery issue fixed. Days at the shop: 3/25 - 3/29 - 4 5/30 - 1 6/12 - 6/18 - 6 7/1 - 7/8 - 7 total - 18 days.

Vehicle incident summary – 2019 Chrysler Pacifica [xxx] is the orginal owner initial incident – [xxx] at 50,779 miles, my 2022 Chrysler Pacifica lost all power while driving on mound road in sterling heights, mi. Officer nathan sears from the sterling heights police department assisted, and the vehicle had to be towed. The diagnosis at the time was complete battery failure—both batteries were replaced. Current ongoing issue – [xxx] at 86,000 miles, the vehicle once again became completely inoperable. It was towed to jim riehl’s Chrysler Dodge Jeep ram in warren, mi. I was initially told the issue was the starter, and I paid $1,200 for the repair. However, the vehicle still does not start. I have now been told the issue may be a blown head gasket or engine failure. The dealership is requesting an additional $2,000–$3,000 just to disassemble the vehicle to determine the exact cause. If it is indeed an engine failure, I’ve been informed that repairs could cost up to $12,000. Concerns: I paid for a starter replacement and the car remains undrivable. There was no resolution or refund offered despite a misdiagnosis. Now I am being asked to pay thousands more just to identify the problem. If this is engine failure, it occurred at only 86,000 miles. I have since found many other Pacifica owners reporting similar failures—battery, engine, and complete loss of power—raising concerns of a potential manufacturing defect. Why I’m reporting this: this vehicle has experienced major, potentially dangerous failures twice—first a complete power loss while driving, and now possible engine failure without warning. If this had happened at higher speeds or on the highway, it could have been catastrophic. I am requesting this issue be investigated for possible safety defects and design flaws.

As I'm driving down the road my mil comes on and tells me to pull over the engine will shut off. My vehicle has had the recall completed. This happened to me on the interstate with my family in the van. This is our only vehicle for the family and need it everyday. Now my dealership is telling me that it isn't a recall issue and I might have to pay for the repairs. This light started coming on about a week ago, and doesn't always come on. But it started to happen more frequently.

The head gasket leaks, full engine replacement is recommended. No accidents, only 79k miles on the engine.

I’m having trouble with my start stop. Sometimes it works and sometimes it doesn’t. Sometimes my motor goes into limp mode for no reason.

My vehicle suddenly lost power driving down the road at approximately 20mph. I rolled to the side and the vehicle engaged the electronic parking brake. It's been at Chrysler dealership for over a week and is now a stars case according to my service rep. .

While driving down the road and slowing down the van put itself into park and shut off. Had to then restart the van.

Van has 55,000 miles on it. Not overheating but noticed coolant reservoir keeps needing to be topped off daily. Also, just received check engine light code for cylinder 5. Shop diagnosed as head gaskets and now need an engine replacement. Absolutely unacceptable for a vehicle with such low miles.

The contact owns a 2019 Chrysler Pacifica. The contact stated that while driving at various speeds on several occasions, there was a clicking noise emanating from the engine compartment and the vehicle began shaking. The vehicle was taken to an independent mechanic, and the contact was informed that the control arm and bushings needed to be replaced. The vehicle was not repaired. The vehicle was then taken to a dealer who was unable to replicate the failure on one occasion; however, on another occasion, the vehicle was taken to the same dealer where it was diagnosed and determined that the alternator needed to be replaced. The failure persisted. The vehicle was taken to the same dealer where it was determined that the sway bar link needed to be replaced. The vehicle was repaired but the failure persisted. The manufacturer was not notified of the failure. The failure mileage was approximately 100,000.

The 2019 Chrysler Pacifica limited with 3. 6l pentastar engine had a check engine light come around 90,000 miles. The vehicle would suddenly lose acceleration power without warning, especially while getting onto the freeway. It was found that there is a known issue with the 3. 2 and 3. 6l pentastar engines where the camshafts begin throwing metal shavings into the cylinders. The issue first presented itself as a cylinder 6 misfire with error code p0306. After replacing the spark plugs, coils, and vvt solenoids, the problem continued until the metal shavings were discovered. The design flaw of the engine causing the camshaft to produce metal shavings into the cylinders that lead to the sudden loss of acceleration is a major safety concern.

Head gasket failure at 68500 miles. It causes a misfire in the engine and could cause an accident from the car bucking once it consumes the engine coolant and also causes overheating and a lot of smoke to come out of the tailpipe making it less visible for others on the road to see, if behind a car like mine.

The check engine light came on. The day it came on, when starting the vehicle, it started shaking while in idle and when initially driving. The same day I had the engine read and a cylinder 6 misfire came up on the report. When I began driving, the car was shaking and it felt like it could stop abruptly which could have caused an accident. Yes, it was inspected and it was diagnosed that the head gasket is blown. Yes, the check engine light came on. It should be noted that when my local mechanic diagnosed the problem, two other Chrysler Pacifica's and two other vehicles with the v6 engine have the same issue.

The contact owns a 2019 Chrysler Pacifica. The contact stated while driving 75 mph, the vehicle stalled, with the start/stop light illuminated. The contact stated that the vehicle shut off independently. The vehicle was not taken to be diagnosed or repaired. The manufacturer was notified on the failure. The approximate failure mileage was 70,000.

I am the mechanic that was hard to work on this vehicle and I am feeling this out for the customer but I am submitting it in my name . Vehicle has code p105c and p0303. The first code is pending permanent and stored, it is saying the intake valve is stuck in a low lift position. The second code is for cylinder 3 misfire. We had the coils switched over from cylinder 3 to cylinder 5 and made sure that the wiring was not damaged and the same code keeps coming back for that cylinder as well as the p105c. It causes the vehicle to start shaking while going down the road almost causing an accident. There is a recall on the 2020 Pacifica having the same code but there isn't a recall on the 2019 which has the same engine.

The coolant keeps disappearing from the resevoir tank and there is a gurgling noise coming from the front driver side. The engine starts rough with the check engine light on.

Around 79,000 miles, my 2019 Pacifica experienced check engine error codes. Upon diagnostics by a repair shop, found that the engine coolant was leaking into the engine due to a bad head gasket and that the engine cylinders were damaged and the only repair is a full engine replacement. The car has been maintained and received regular oil changes and should not fail in this manner at less than 80,000 miles. Reading through various forums I see this is a known issue with the 2017+ model year Pacificas.

Check engine light cam on then a message "stop safely vehicle will shut off soon" this is related to recall 23v-010.

My 2019 Pacifica hybrid started showing a message around 07/19 “service charing station” followed by service park brakes, service parking system and was not able to start or control anything in the car. After 15 to 30 minutes it started working and no errors. On Friday, 07/26, car stopped all of a sudden (luckily my family was in the parking lot) and showed a different message “stop safely. Vehicle will stop soon” message and after that it went completely dead. This is a concern that the vehicle would stop when driving and making the vehicle not responding to anything. You cannot control (brakes, driving modes, light) anything and when aaa jump started the car was in “running” mode and asking to power on the vehicle.

The transmission shifts/jerks hard and hesitates/struggles to accelerate at times. It has even shutdown numerous times while I was at a traffic light.

While @ highway speed this vehicle lost ipower steering, power braking and the engine stalled out…this latest event prompted my complaint and was the third time I have experienced this situation. In all three incidents I was simply able to coast to the side of the road and stop. Thankfully after a few attempts to restart the vehicle started and ran. It was very frightening given it lost total power on all three occasions without notice or warning it like it just turns itself off. I contacted rollx vans the folks from whom we purchased this handicap transport vehicle and they informed me of a safety recall v53 for 2017-2019 Pacificas. The recall details the exact symptoms of what I experienced. I took the recall information and the vehicle to a local dealership larry h miller Chrysler, tucson az and they mostly dismissed my account and said there is no recall on my VIN despite the v53 recall. They said the tech couldn’t get it to duplicate and situation. They said they checked the grounds and it’s all ok. I am not convinced considering the timeline of their alleged repair and the answers I rec’d from the service writer when I asked specifics about the repair. I suspect they simply test drove it when it did not duplicate the situation they said it’s ok.

Engine was running low on coolant due to malfunction of heads computer did not warn me or temperature senser gage showed normal engine needs replaced now.
