2018 Chrysler Pacifica complaints

The van continues to accelerate when I'm braking. This has happened 4 times after an hour or two of driving the freeway. As we were exiting the car continued to Rev up as we applied the brakes. Thank God the light was green. Another time I tried to park and as I was braking the car was accelerating. I had to quickly put it in park position. The van is in the shop, Hunter Dodge, now and they ran a diagnostic test and failed to find a problem.

Blown head casket at only 64000 miles. Engine light on and antifreeze I’m told is leaking now. No warranty or recall with the 2018 Pacifica but there is for the same issue with the 2017.

The check engine light came on after 2 weeks of owning the car. It threw a Code P0303. We replaced the coils on 1-3-5 and spark plugs on all cylinders and the check engine light came back on after 1 week. It finally would not start. Our mechanic has removed the head and gasket and discovered the cylinder 3 was full of water and water and oil in the oil pan creating a gooey sludge. This is apparently an ongoing problem with this engine to the point that gaskets to replace the head gasket are very hard to find.

We were traveling at approximately 45 miles per hour, slowed down around a bend in the road and hit an ice patch. The vehicle spun towards a truck stopped at a stop sign. We hit the driver's side of the truck with the driver's side of my vehicle. We continued to spin and hit the truck again with a side impact. and spun again after the second impact. The front airbags deployed but the over head side impact airbags did NOT deploy. My wife was driving and hit her head on the drivers side window resulting in a large contusion on her forehead. The only safety notice or recall information we had for this vehicle was concerning the electric start and ignition components with the batteries that left our vehicle stranded at one point, until we had that repaired. We never had any notice or alerts of any air bag deficiencies in the vehicle. The driver's side and driver's passenger side airbags should have deployed upon the impact. We had our two little girls 2yr and 9mo old, 12 yr old, myself, my wife and grandma in the vehicle. No one else was injured in the vehicle except my wife the driver, hitting her head on the side window.

Oticed that the CEL had come on, and after reading the codes, I found out that there was a cylinder 5 misfire. To fix the issue, I decided to replace all the spark plugs and ignition coils, and after putting everything back together, I erased the codes. However, the following day, the same code appeared again, and I realized that the coolant level in the reservoir was low. I performed a pressure test on the system and ran it to temperature, but there were no coolant leaks. While the car was running, I observed bubbles in the reservoir, and these signs pointed towards a blown head gasket. After checking online for Pacifica common issues, I found out that head gasket failure is one of the main complaints. As a mechanic with 13 years of experience, I know that these symptoms indicate a blown head gasket. Unfortunately, due to this issue, I had to leave work twice as my wife and four kids were stranded 30 minutes away from the house. This is not acceptable, and I've never had a vehicle blow a head gasket before.

After radiator was replaced by the dealership, our car has been experiencing coolant leaks that we have “repaired” twice, however the issue keeps coming back within the week. We are also experiencing stalled engine will driving, where the car just slows down instantly or stops.

Occasional loss of power steering and or locking up of the steering wheel resulting in excessive force to overcome the locked or "catched" position. Dealer has inspected and says that the electric steering gear is faulty.

The contact owns a 2018 Chrysler Pacifica. The contact stated that while driving at an undisclosed speed, the engine temperature gauge displayed that the engine was overheating. The contact drove the vehicle to a safe location and waited for the engine to cool down. The contact was able to drive the vehicle to the residence. The vehicle was towed to the dealer where it was diagnosed with a blown head gasket. The contact was informed that the head gasket needed to be replaced. The vehicle was currently being repaired. The manufacturer was made aware of the failure and agreed to supply the parts needed for the repair. The failure mileage was approximately 83,538.

The contact owns a 2018 Chrysler Pacifica. The contact stated that the main battery and the auxiliary battery had been replaced on multiple occasions. The dealer had not yet determined the cause of the failure. The contact stated that the frequent battery failures caused the vehicle to stall while driving at various speeds with the battery and check engine warning lights illuminated. In addition, the contact stated that the vehicle was diagnosed with a cylinder #3 misfire. Also, the contact mentioned that the vehicle would jerk forward upon depression of the accelerator pedal without warning. The vehicle was taken to the dealer for a diagnostic test; however, the dealer was unable to determine the cause of the failure. The manufacturer was not notified of the failure. The vehicle was not repaired. The failure mileage was approximately 46,000.

I have had transmission problems with this van since I bought it. Had it in the shop several times. It jumps or pops and throws vehicle forward. I also have had to replace the large battery and the accessory battery multiple times. This has left me stranded many times bc it will shut off while driving. Last time was today 11/01/2023. Large battery and alternator was good. Accessory battery dead completely and replaced for free since it was in warranty still. But they say it has caused my van to misfire in cyclinder 3. Car has only been maintenance through Elliot Chrysler Dodge in Carthage Tx

Failed cylinder head (misfire p0304). Need to have engine rebuilt or replaced. Also had oil cooler failure, losing coolant and oil. 71k miles, just over the 60k power train warranty. Need dealer to help fix but they are booked for next 3 months. Car initially cut out on the road in traffic after auto start stop, was scary and safety risk with family including kids onboard. Confirmed with independent mechanic, but also going to dealer as it is specialty work for that engine.

Coolant leaking into cylinder 4 causing a misfire and engine overheating resulting in blown head gasket. Vehicle had only 50K miles at the time; however problem was not diagnosed until just after 5 year mark (powertrain warranty expiration).

Suddenly our Pacifica would not start and started cycling through over a dozen error messages. We were finally able to get the vehicle to start and took it to the dealership. They confirmed that the star connector needs to be replaced. After looking at many forums, this appears to be a fairly common issue among the early hybrid pacificas, to the point that I felt I should report here, especially given the recalls that have already happened due to the electrical system in the car. We just got the last recall done in August and already we now have a ~$1000 bill to repair the electrical system again. Please have someone look into how many of the pacificas need this particular connector replaced given the prevelance of people with the same issue online.

At around 84000 miles the engine light came on and the van started spattering and when you start it. The first place I took it to said it was cylinder 6 was misfiring and they replaced the coil and spark plug. The van check engine light came back on and it started to overheat so we took it back in and the coolant was empty. They refilled it and I got it into the dealership and they found that it was the head gasket so they placed it. Upon picking it up the check engine light came back on and they replaced a cam shaft sensor.

What component or system failed or malfunctioned, and is it available for inspection upon request? The shifter module fails or malfunctions and it put the vehicle in park. All the electronic controls in the vehicle malfunctions even when the vehicle is driving like the ABS, displays, throttle, ADAS and all other controls How was your safety or the safety of others put at risk? The vehicle suddenly starts throwing the warnings while you are driving - sometimes in the freeways, it also jerks, throttle and other controls and displays goes blank, you are not sure even if the emergency flasher is activated Has the problem been reproduced or confirmed by a dealer or independent service center? Yes Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Yes Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? It started almost 2 years ago in Dec 2021 when the check engine light first came, dealer tried to fix by replacing the 12 volt battery but the problems started slowly and in August 2022 disabled the vehicle completely. The vehicle had been with the dealer most of the time since then and its still not fixed as of today

We could not locate an active coolant leak for almost two months (brought to several mechanics.) Added dye to the coolant and it showed in the oil. Waited over a month for an appointment with the dealership and was finally told that it was a bad Head/Head Gasket, Oil pump and would also need a new catalytic converter etc.... It is apparent from the chrysler forums that this is a VERY common problem. #5 cylinder, bad coolant channel design leading to engine failure. Even the mechanic at the dealership said (ON VIDEO) that this was a common issue. Chrysler is WELL aware of the issue but refuses to redesign or assist customers when the failure occurs. This is CLEARLY a safety issue that begs for a recall.

My van experienced sudden misfiring when I tried to start it. To address the issue, I took the van to the Chrysler dealership in Buford, GA. After their assessment, they informed me that cylinder 3 had a crack, and it necessitated the replacement of the entire engine. They provided a quote for this repair, which amounted to $13,000. I've been diligent in maintaining my van, regularly checking the oil levels, and there were no warning signs or indicator lights until the check engine light came on when the misfiring issue began. It's worth noting that my van only has 81,000 miles on it. While researching this problem, I came across a forum where numerous individuals shared similar experiences, indicating that this kind of catastrophic engine failure shouldn't be so common. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Engine sputtering, engine light came on P0303 cylinder 3 misfire. Light would come on and off every couple of days. Diagnosed with a blown head gasket at ~51,000 miles.

We began having major issues with our van in October 2022. There were numerous incidents of loss of power and sudden increase in temperature gage. We kept fluids checked. Kept oil changed on time. We reported this to the dealership multiple times before they agreed to fix under warranty. Even after fixing factory recall (which we were charged for by the dealership) and then replacing batteries, we continued having issues with loss of power and surge in temperature gage. July 8th of 2023 engine light came on and temperature gage shot up, van stalled at the intersection. I had My self and FIVE kids in the car. This was accompanied by a sudden loss of fluids. We had the van taken to another repair shop who then told us the head gasket was blown. This happened just 4 miles after our warranty lapsed. We had to have the entire motor replaced out of pocket. More than $8,000 in repair costs so far and the van I still making noises and not driving correctly.

62000 miles on the vehicle. Bought used from Chrysler dealership with 55K miles. Check engine light came on after starting in morning, rough idling. Brought it to dealership and was diagnosed as cylinder-4 misfire. Dealership replaced spark plug and coil, switched fuel injectors. Drove away from dealership, week later engine light came on again. Went to the dealership, they performed a block test, confirmed 4th cylinder head needed to be replaced. This is an extremely common problem in 2017-2018 Chrysler Pacificas. This is a travesty and needs to be rectified.

Driving through a parking lot when the van said shift to park and completely shut off while moving. Lost power steering and acceleration. Car then would not restart. Husband came and we hooked to his battery and somehow it cranked and we got it home.

Several near-accidents yesterday and today. Steering wheel randomly locks up when driving. This is an extremely dangerous situation for my wife and 4 children riding in the van. You have to physically force the steering wheel back over, which can easily result in over correction which could also cause a crash. No warning lights on at the time, and has happened 4 times yesterday and once today already. How is this not a recall?!

Our engine has stalled while driving the vehicle at least four times since July 1. The engine begins to shudder, and the car will not accelerate, and then the engine completely dies. After it happened today, it was not possible to restart the engine or put it in gear. My and my family's safety was put at risk because the vehicle was inoperable. Three times this happened on major interstates with traffic moving at high speeds. I had to move my children and their car seats into another vehicle while traffic passed. We have had the vehicle in for service at least three times, at least twice at Chrysler dealers. The problem has not been reproduced (yet) but this latest time it completely disabled the vehicle so expect they will see more of the problem now. After the engine cuts out, we get an electrical warning light that flashes briefly, plus a check engine light, and a message that instructs to move the gear shift to P to start the vehicle and another that warns that the Start/Stop system needs service. We have had these all serviced, the fuel pump and battery replaced, and have been told the problem is resolved and yet it keeps happening.

Vehicle is 5 years old and at 90,000 miles. Head gasket blew causing several thousand dollars in damage. This seemed very early to have to do this to the engine. I wanted to report in case this is a persistent issue with this particular model of car. If it is a consistent issue I would like to see. A recall issued.

My 2018 Chrysler Pacifica has a blown head gasket. It has been to a Chrysler dealership and an independent auto repair shop. Both places told me that this is a known defect and commonly occurring problem with this engine. I have conducted my own research and it definitely appears to be a known defect and common problem. I was told that the head gasket could be replaced but more problems would follow and paying the large repair bill wouldn't guarantee the van would be problem free. The best option I've been presented with is to replace the engine completely. It is very disappointing to need to replace an engine in a vehicle that is only 5 years old and just barely over 100k miles.

Engine Misfire was reported and did all the normal maintenance to correct from a certified mechanic. Misfire was still happening so I took it to a dealership and they couldn't find the issue. They wanted 2400 just to break the engine down to find the issue. A local mechanic did a coolant test and read the engine code to see that it was a coolant leak in the oil. Blown head gasket is the culprit. He suggest while you have it apart you should actually do both sides.

P0303 code. Ended up being a blown head gasket and required entire engine replacement from damage caused. Refused warranty as it was brought into dealership in Aug 5 2023 but warranty ended July 25 2023. All maintenance had been performed

The contact owns a 2018 Chrysler Pacifica. The contact stated that while her daughter was driving at an undisclosed speed, the vehicle stalled. The contact stated there were no warning lights illuminated. The contact related to the failure NHTSA Campaign Number: 23V010000 (Electrical System, Hybrid Propulsion System) however, the VIN was not included. The vehicle was towed to the dealer; however, the vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 50,000.

Van just unexpected shutdown no warming light nothing ! This is a handicap van rear entrance !!! On Tuesday August 8 2023, Daughter and handicapped granddaughter riding in van it just stopped she had to coast in the middle turn lanes until help arrived Did get daughter out in wheelchair push across 3 lanes traffic to safe very hot that day... On the NHTSA says as of January 17,2023 compaints on 2018 Chrysler Pacifica With inspected engine shutdown..

I purchased this vehicle used in 2022. A few months after purchase, I began to notice that while I was going through a sweeping curve in the road and traveling faster than approximately 30 MPH, the steering wheel would stick at approximately 1 o'clock or 11 o'clock depending on which way I was turning while attempting to straighten the wheel back out after completing the turn. To get the steering wheel to return to center, it takes forcible action. If not careful, this forcible action can cause you to overcorrect from the turn. This becomes quite dangerous especially on narrow one lane roads. This problem has been discussed with multiple service centers, but has not been able to be diagnosed. No warning lamps are present in the vehicle and all other systems seem to be working fine.

The contact owns a 2018 Chrysler Pacifica. The contact stated while stopped at a traffic light, the vehicle stalled. The message "Shift to Park" was displayed. The contact stated that she shifted to park(P) and turned off the vehicle and the vehicle failed to restart. A local mechanic met the contact at the scene and assisted in restarting the vehicle. The contact was able to continue driving. The contact stated that the failure recurred intermittently. The vehicle was taken to the local dealer several times; however, the dealer was unable to duplicate the failure. The contact stated that the failure had been recurring increasingly. Additionally, the contact stated that the failure started to occur after the head gasket was replaced. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure and informed the contact that they could not assist because the dealer had not performed a diagnostic test. The failure mileage was approximately 115,000.

Loss of power, multiple times, most serious @ 70mph freeway, baby on board, 500 miles away from home. No tow, no rental, no way to get home. Previously reported to dealerships, won’t fix issue, quotes for $7k of service, issue still persist.

Cylinder 3 misfire, combustion gases in coolant, coolant consumption but no leak, probable failed head gasket

A blown head gasket (and possibly warped head) were causing a cylinder 3 misfire. The vehicle has only 70,000 miles and has had regular maintenance performed. It appears the motor design is faulty, likely causing a build up of heat in the engine compartment or internal to the motor resulting in blown head gaskets. This is apparently a common problem and Chrysler should develop a solution to handle the issue.

Cylinder head inside the engine has a Crack with antifreeze leaking into the engine. I had been driving the car prior to being able to make an appointment at the dealership. Luckily there was not a crash due to this.

The contact owns a 2018 Chrysler Pacifica. The contact stated that while driving at an undisclosed speed, smoke came from underneath the hood; however, the contact turned off the vehicle. The contact waited for the smoke to settle before restarting the vehicle. The contact was able to drive the vehicle for a short distance, and then the vehicle was towed to the dealer. The vehicle was not diagnosed due to extensive melted engine parts. The manufacturer was not made aware of the failure. The failure mileage was approximately 60,000.

The engine is failing due to poor design and parts. Coolant has leaked into the motor causing a misfire and likely a ruined engine. With this damage, the engine can stop at anytime risking all occupants especially if driving at higher speeds. This is a minivan intended to safely transport families. It has not been to the shop yet. There was first a fuel pressure sensor check engine code and then after that was fixed we scanned the stats few weeks later and now there is a misfire. This is all a far too common issue for Chrysler Pacifica with the 3.6 L Pentastar motor.

Currently have 62,254 miles on my car and the head gasket is now faulty requiring a repair that’s almost $4,000. Check engine light came on prompting it to be looked at and head gasket was root cause. Appears to be a very common issue with Pacifica’s but no service bulletins or recalls associated with this issue yet.

The service electronic stability control warning is populated after the vehicle stalled while driving on the freeway. The vehicle often jerks and stalls when taking off or driving at slow speeds but this is the first time at freeway speeds. This early caused an accident for me and my family.

My car won't start it says that the engine or accessory is on when it isn't. I had this same problem last year during covid so I replaced both the batteries last year. Now it's doing it again. This time how ever the light is flickering on the drivers side. The doors when I first got it and sometimes says still that there not enough power to operate sliding doors.

In November 2022, roughly 2 weeks before Thanksgiving our 2018 pacifica showed an engine code on the way home, it read to be a misfire. We were already enroute and near home so we cotinued driving. The low coolant light came on briefly as we were pulling into the driveway and the engine became hot. When I looked under hood I could hear a gurgling noise and noted th coolant resovoir to be empty. The next morning I added coolant and used a Gasket leak detection kit to confirm a blown head gasket. Vehicle was dropped off on a Monday and was in the shop for nearly a month waiting on parts. We were very fortunate to be so close to home. Failure occured under warranty but upon research found that the issue was fairly common among vehicles with this engine, some failures as low as 40k on the engine.

- The car still has open recall Z11 ( RU PHEV hybrid traction battery fire). - The car had open recall XE1 RU PHEV transmission open. - The car became stranded refusing to put the transmission into gear. - Had to tow the car to the dealership. The dealer stated the traction battery fuse was blown. The dealer could not pinpoint the root cause of the issue, nor did chrysler have parts readily available to fix. The car still shows there's an open short. - The dealer could not complete diagnosis because of the Z11 recall. They stated that the traction battery can not complete self check procedure. - Chrysler is unresponsive in following up on the issue.

Sliding door closed on my daughters hand even though the dealership claims the sensors work fine.

I purchased this vehicle Certified Used from a Chrysler dealership 2/2020 and it did well until about 1 month ago. The motor was running "rough'' and sometimes losing power. Diagnostic code P0303 came up and I am told by our mechanic that the 3rd cylinder is ''blown''. Most likely due to dropped valve guide and / or warped head. When I began to look up reasons for this problem online, MANY problems just like this for the 3.6L V6 Pentastar motor. I was told not to drive it any more than I absolutely have to as it could / will lose power without warning. I don't know if this has been confirmed by dealer or ISC but it is on many forums and subject to class action lawsuit. There has been no other inspection besides my local mechanic. Engine light did come on when problem first began about 1 month ago.

Got a check engine light for misfire cylinder 4. Take it to a dealer and told its blown a head gasket at 76k miles. They act like this has never happened. Start reading all the forums and it’s a widely known issue that the manufacturer won’t correct. Could have an accident or catastrophic failure caused by their negligence.

GPS does not show accurate location. GPS location is showing vehicle location is 100s of miles from the actual location. This makes GPS unusable, and other vehicle functions that require the vehicles location to be unusable as well. There are extensive documented reports of this incident online.

Rough idle when starting cold. Cylinder 3 misfire. Loss of coolant. Jolt when accelerating .

The transmission shifts hard when traveling around 14 mph then will jerk (like being rear ended), slows down then accelerates on its own. I'm afraid it will cause an accident. Chrysler said it is supposed to work like that and nothing is wrong with it. I have had 3 diagnostic tests done it and it shows nothing is wrong.

Engine noise and rattling as well as coolant levels dropping dramatically. Mechanic advised head gasket repair and upon further inspection a NEW ENGINE on a 2018 vehicle. With more research, I see this has affected other Pacifica owners.
