2017 CHRYSLER PACIFICA Engine Problems

The CAN BUS connector (found in the glove box area) fails periodically and without warning. It affects everything on the vehicle; it stops the car from shifting, car won't start up, windows stop working, all of the warning lights turn on, etc. The issue seems to be a manufacturing defect; the soldering cracks after a while, so the low voltage applications malfunction. Many people have noticed the problem, but the dealerships refuse to do a recall or address the issue properly. The vehicle has been in and out of the dealership probably 10 times in the last 7 months or so. The vehicle is available for inspection upon request. This problem is unsafe because it can occur while driving on a freeway which can cause an accident. Every warning light comes on when the malfunction happens.

I keep getting the same codes every few weeks. P0732

Oil leak from oil filter housing

2017 Chrysler Pacifica at 70k miles, check engine light came on. After engine warm up, engine starts to rough idle. Diagnosis is misfire on cylinder 2 (code P0302). In addition, vehicle voltage fluctuates in gage cluster between 12-14 volts. No issue until engine is warm and no issue above idle or with load. Injectors were checked and fine, coils and leads were replaced. Fix did not work. Took to Chrysler dealership for addition diagnosis. Dealership diagnosis is cylinder head warpage due to overheating. Single owner of vehicle, regularly maintained and with no “low coolant” engine light.

It loses power alot especially uphill. It smells like burnt oil all the time. Smokes out exhaust. Hesitates anytime you put the gas down. And then clunks around sometimes too

The van have issues with a head gasket, Chrysler is aware yet the dealers keep selling the van with this known problems, I reached out to Chrysler and they said they cannot help. I had the van less than a year and I had the van serviced multiple times. Im attaching this link to show you guys that there ia a lot of people having the same problem, everything starts with the smell of the coolant then the misfire PO201, po301, then after taking it it was po305 and po205, https://youtu.be/sUfTxNBkRLU?si=JoLL29t6YbHZIiVg they speak on the video how they replaced the apparently bad part then the codes come back. I had this vehicle less than a year and I had so many issues, in my search I found this happening to multiple pacifica owners. vehicle starts misfiring creating a real possibility of having an accident as the car speed had to...

The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The failure mileage was approximately 128,000.

I do all routine maintenance on my car and do my standard oil changes on time. I only have 80K miles on my car and may now have a head gasket issue. I have seen many online posts that there are many users that have experienced this issue and some looking to possibly do a class action law suit. Has this issue been looked into as a potential recall? When speaking with the dealership I advised that my check engine light had come on and I took it to my local repair shop and the code indicated it was either a coil or spark plug that needed to be replaced. My repair shop checked and it was the spark plug that needed replacing. The car was fine for 2 weeks then the engine light came on again. When speaking with the dealership they said that yes the code will usually...

Engine ticking,blind spot not working

The contact owns a 2017 Chrysler Pacifica. The contact stated that while his wife was attempting to park the vehicle with the brake pedal depressed, the engine unexpectedly began to rev. The vehicle then accelerated inadvertently, resulting in a collision with a pole in front of the parking space. There was no damage to the pole. The air bags did not deploy. The vehicle was towed to a collision center, and the insurance company declared it a total loss. No police report was filed. No injuries were sustained. A dealer was not contacted. The manufacturer was not notified of the failure. The failure mileage was 76,000. The VIN was not available.

After the latest 73B recall, the engine light sporadically turn on. In one occasion, while cruising at low speed ~25mph in the electric mode, the vehicle switched to gas engine mode even there was 16 electric miles on the battery. This issue was not there prior to the recall. Need investigation on the software reliability and the underlying battery issue

Blown head gasket

The check engine would blink and the engine would shutter for a few minutes when the van would start. It would drive around normal. A few days later the van would not start at all. We checked both batteries and they were not the issue. We then towed the van to a Chrysler dealer who checked the starter and alternator, those were both good. They stated the engine was seized and quoted $15,000 for a new motor.. the van has 120,000 miles on it. The van is worth less than the quote we received.

I noticed when I am driving the van would lose power and or the the transmission would shift very hard and stall the car engine would then take off very fast or slow. I reported the car to the dealership that I purchased the car from and to the customer service at the Chrysler Pacifica Corporation no one will help me I told them that the car was very dangerous while driving.

While stopped in traffic, the car started shifting from Drive to Neutral and Parking, the lights of the shifting wheel started blinking, and it was not possible to turn off the engine. After ~20 minutes, it stopped doing that and I was able to turn it off. 10 minutes later I started the engine and I was able to drive home but the steering wheel was very hard to move and the Check Engine light and there was a message in the cluster to take the Power Steering Assist and the electronic stability control system to service, but while stopped in the driveway with the engine on, it did exactly the same and I wasn't able to power off the engine. I wasn't able to start the engine again after that, the lights of the shifting whell kept blinking. I took the car to an independent mechanic and he was...

I am reporting a serious and ongoing safety defect with my 2017 Chrysler Pacifica (VIN: [XXX] , current mileage 51,875). The vehicle stalls and shuts off unexpectedly while driving, including in intersections, creating a life-threatening hazard. I have reported this issue multiple times to CarMax and Prestige Chrysler Dodge Jeep Ram in Las Vegas, NV, but it remains unresolved. Key points: • First reported to CarMax on 2/6/2024 (Invoice #[XXX]). • Battery health test passed on 3/1/2024 (Invoice [XXX]). • Dealership later misdiagnosed the problem as a dead battery and charged me $837.95 for a replacement on 10/11/2024 (Invoice #[XXX]), which did not fix the stalling issue. • I returned within 7 days with the same safety complaint. • Multiple service attempts have failed to permanently resolve the issue.

On Thursday May 30th was the first incident of the vehicle shutting down we were able to start it back up almost immediately within seconds on the 2nd occasion I was on a street with cars behind me going down to make a turn the stop start did not engage but we were still a ways away from the stoplight and suddenly the engine stopped no signs other than just stopping I could not start it back up I look down there was no indication of any issue other than a stalling so put it in part turned it off turn it back on no start try it again didn't work could not turn it over to neutral to get off the road police came while I had somebody disconnect battery and reconnect it to try to get it started again there was no less battery power on the engine...

The coolant leaked into the engine and blown the headgasket. This has been confirmed by Pepboys who work on my car. It has not been inspected by manufacturer or others. It started by causing the ignition coil to fail and the engine would start rough and check engine light would come on. started around 5/1/2025

The engine failed at 57,400 miles. My wife was driving with our kids and engine locked up. I took to the dealership and they said that the engine block and head is warped and cracked. The engine needed to be completely replaced. My warranty period was over and company did not want to stand behind the product and help with any repairs. They said the vehicle overheated but that never happened during this time.

We are the original owners of this vehicle, which has been consistently and properly maintained. Recently, the vehicle stalled unexpectedly in the middle of the highway and would not restart, creating a significant safety hazard. The check engine light illuminated, and the vehicle could not be shifted into neutral, preventing it from being safely moved out of traffic. After the vehicle was towed to the dealership, we were informed that the starter had failed due to coolant leakage from a compromised head gasket. This coolant intrusion damaged the starter, rendering it inoperable. The dealership advised that while the starter could be replaced, it would likely fail again unless the underlying head gasket issue is addressed. We have since learned that this is a known and recurring issue with certain Chrysler models. Unfortunately, Chrysler has not issued a recall, nor have they provided vehicle owners with any formal notification or long-term...

-Stalled while driving -Loud clanking upon start -No diagnostic info was accessible -Replaced Cadillac converter, was glowing red -Once replaced still hot, 10,000-20,000 degrees -

P0302 code triggered the CEL. Spark plug showed signs of coolant spark plug, and leak down pressure test presented a leaking cylinder head gasket. Disassembly of the air intake manifold revealed the oil cooler was leaking oil and mixing oil with coolant.

Had to have PLASTIC oil filter housing and Oil cooler replaced due to warping from the engine heat and leaking into engine bay causing a burning oil smell throughout the entire vehicle. Was replaced by Meineke car care with an aftermarket Aluminum constructed part. Constantly having transmission issues since the vehicle hit 70,000 miles. Now at 139,000. Fluid flush and fill done and transmission fluid was ridiculously thin and dirty despite it being known as a SEALED transmission and being told by Chrysler that no fluid changes should ever need to be done for the transmission. Seems as though the transmission may be slipping, and is shifting very hard after having the fluid changed.

Cylinder 5 was misfiring causing driveability problems. If the engine were to fail completely, then the vehicle could become uncontrollable and cause an accident. The manufacturer knows about the problem but has not issued a recall. The vehicle was repaired by the local car dealer. The problem occured around 57000 miles on the odometer. A check engine light did come on.

The contact owns a 2017 Chrysler Pacifica. The contact stated that while driving at an undisclosed speed, there was an engine misfire with the check engine warning light illuminated. The vehicle was taken to the dealer, where it was diagnosed with a misfire in cylinder #3. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The contact was informed that the vehicle was undrivable. The dealer declined to release the vehicle without repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 74,600.

Engine has a blown head gasket at 80k miles. Number 3 cylinder keeps misfiring due to the engine coolant being injected into the cylinder due to the blown head gasket. Poor engineering with this engine and I’ve read several others have experienced this same issue. Please do a recall for this issue due to the warranty not wanting to cover this!

The check engine light came on. Upon using a code reader, a code for a misfire in cylinder 3 populated. The ignition coil was replaced for cylinder 3. About a month later, the check engine light came back on and all 6 spark plugs were replaced. My vehicle had some rough starts periodically. As time went on, the rough starts turned into serious shaking. The check engine would come on and be gone in a day or so. Every time the code reader read cylinder 3. After months of trying to trouble shoot and do what we could, we took it to a mechanic where they informed us that my vehicle had a blown head gasket. They revealed to us that this is a very common problem with the particular engine, 3.6L Pentastar. This is a problem that they have seen for years in this particular engine. The mechanic had...

2017 Chrysler Pacific diagnosed with leaking head gasket at ~65000 miles. Initially diagnosed from a check engine light code for a cylinder misfire. My private mechanic said that he has done 4 of these in the past month (Jan 2025). He said this is a costly repair that should not happen with this low of mileage. In exploring the problem, it appears that it is a known issue.

Unknown, engine light came on flashing while driving. Car has been repaired by the dealership a few weeks ago and replaced the fuel pump.

The oil filter housing and oil cooler unit is made of plastic, mounted to the central engine (metal). It warped with heat and caused oil to leak into the valley of the engine and cause failure of bay 3 and 5 fuel injectors which caused multiple cylinder misfire. My engine experienced this problem for the first time in a busy intersection. With the engine heaving I had to pull over and tow the van to a shop. The faulty oil cooler unit was confirmed by dealership diagnostics and was not covered under warranty. I have the original part. This a recurring problem with many other drivers online and an aluminum aftermarket part has been made to solve this problem. The original part should be recalled and replaced by Chrysler. The EGR hosing is made of brittle plastic and split/cracked of its own accord. I have pictures and most of the...

[XXX] my check engine light came on and started blinking as I was driving. I then noticed that my car was sputtering. I stopped my car immediately and had it towed to a dealership at that exact point I had just over 64,136 miles on my 2017 Chrysler Pacifica. The following is the work that they performed on my vehicle. CONCERN VERIFIED. VEHICLE HAS AN ACTIVE MISFIRE, CHECK ENGINE LIGHT IS FLASHING. SCANNED VEHICLE FOR CODES AND FOUND MISFIRE ON CYLINDER 3. REMOVED COIL AND SWAPPED TO CYLINDER 1. SPARK PLUG REMOVED AND SWAPPED TO CYLINDER 5. RETESTED. MISFIRE MOVED TO CYLINDER 1. REPLACED IGNITION COIL AND ROAD TESTED VEHICLE. AFTER VEHICLE WAS WARM THE MISFIRE ON CYLINDER 3 RETURNED. SWAPPED FUEL INJECTOR TO CYLINDER 2. MISFIRE STAYED ON CYLINDER 3. REMOVED COIL AND SPARK PLUG FROM CYLINDER 3 AND BORESCOPED CYLINDER. FOUND COOLANT LEAKING INTO THE CYLINDER. RECOMMEND REPLACING...

Blown head gasket and oil cooler leak

My car shut down on highway and the dealership said it was the terminals on the battery being dirty it happened agin so I had the battery changed then it did it again and the dealership changed one spark plug , one coil pack then it happened again changed all spark plugs and coil packs my car did it again and now I’m being told I’m probably going to need a new engine I notified Chrysler telling them this has happened several times and they said there was nothing they could do

My car will start, i will start to drive and when i am driving a “electrical stability” label will pop up on the dash and then the battery icon and check engine icon will show up on dash. My radio screen will go blank and then the car will shut off completely. It will then pop up on the dash and say stop safely vehicle with shut pff soon

head gasket leak at 69k , crowley chrystler replaced head and now at 101 k leaking again

Check engine light. Cylinoid misfire reported, #3. Replaced. Check engine light reappeared. Coolant leak. Coolant checked with die solution to check combustion mixture. Tested positive. Head gasket leaks diagnosed. Possible head gasket crack. Vehicle was unsafe to family driving as failure could occur on highway. Family member had to pull over on side of road to prevent overheating.

This vehicle has been totaled about a week ago. I meant to report this earlier but since we're moving (military) I never had the chance. Around april 2023, I noticed my pacifica had a misfire. I assumed it was plugs and wires so I replaced them - check engine for misfire went away. A few weeks later same thing happened. This time, I was loosing coolant. Took it to a chrysler dealer top have it properly diagnosed fearing the worst - they told me without even looking at it that this particular year of pentastar on the pacifica has blown head gaskets and that they change them all the time. I decided to repair the head gasket myself and I did so and drove the vehicle up until last week when it was totaled. There are many others experiencing this same issue with the pacifica and Chrysler needs to do...

2017 through 2024 Pacificas with the 3.6 Pentastar engines have problems that in case of coolant leaks in the system, it leads to a engine coolant reservoir low level which allows air to enter the system and causes unrepairable damage to the engine that needs it to be replaced. ROOT CAUSE is FAC / Stellantis / Chrysler FAILED to install a simple and cheap engine coolant reservoir low level warning sensor which would save the majority of the people with blown head gaskets all this grief and expense. The 3.6 Pentastar engine uses aluminum heads with an open skirt design which means that the cylinder heads are weak and prone to warping under ANY overheat condition.

The contact owns a 2017 Chrysler Pacifica. The contact stated while driving at an undisclosed speed, the contact noticed a burning odor inside the vehicle. The vehicle was taken to an independent mechanic where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced. In addition, the contact was informed that the engine was operating on five cylinders instead of six. The vehicle was not repaired. The contact stated that previously the check engine warning light was illuminated, and the vehicle had been taken to an independent mechanic several times. The contact was informed that the failure was due to a plastic piece that was missing from the engine. The contact stated that the independent mechanic reset the vehicle and the check engine warning light was off. The manufacturer was not made aware of the failure. The failure mileage was unknown.

The incident first occurred in our 2017 Chrysler Pacifica while my wife was driving our Kindergartener to school. The vehicle stalled in high flow traffic almost causing her to get rear ended. Dash said to shift to park and turn van off. Was unable to get it restarted and had traffic blocked in the left lane for almost an hour waiting on a tow truck. Took it to the dealership and they told her it was a bad battery. Paid almost $400 to replace the battery, and today (11/16/2024) it just did it again while pulling into a gas station, still halfway in the road. Van said “shift to park to start engine.” Shifted and engine shut off but was able to restart it this time. Was unable to move shifter dial and sudden loss of power almost caused 2 wrecks so far within 2 months of each incident. Each...

The Check Engine light indicated a misfire is cylinder 1 and the car was running roughly. After changing the injector, spark plug and coil wire, the problem continued. The mechanic finally determined there was radiator coolant in the exhaust indicating a failure of the head gasket. A leak in the engine block, and improper combustion can lead to a myriad of safety issues. A check online revealed this to be a common problem in this Chrysler engine in 2017 in the 1-3-5 cylinders with some contributors suggesting an improper casting of the engine block during manufacture. It commonly appears around 60,000-75,000 miles, generally after the power train warranty has expired. My van was at 75,729 miles. The cost to repair the vehicle was $3488.48. The repair was done by my trusted mechanic as I am sure that the Chrysler dealer would be far more expensive. This is due to a...

Our vehicle started to shudder when we started. We took it to the dealership, who initially was unable to identify an issue. They then, a day later, identified that the head gaskets needed replaced. This required a significant repair. Reviewing online, there appear to be hundreds, if not thousands, of similar issues when this type of vehicle reaches approximately 70,000 miles. Our vehicle is a little beyond 70,000 miles. We have also had some other issues, including about 1.5 years ago where the vehicle would randomly turn off while driving. We did take this in for a repair.

Engine Coolant leaks inside the engine Cylinder #5 without warning and cracked the engine block cylinder head #5. This has happened 2 times on this vehicle replacing the engine once. Vehicle has been maintained in accordance with manufacture recommendations.

2017 Chrysler Pacifica with 103,000 miles experienced a blown head gasket.

The vehicle is available for inspection. At an intersection the vehicle abruptly turned off, while the engine was running and in drive. Children were in the vehicle and I was very scared and in shock when it happened. My car just randomly turned off, while I was sitting in the middle of an intersection and the vehicle was in drive (obviously). I was able to turn it back on, but it was very dangerous and could have killed us if a car had come through the [XXX] intersection while we were stuck there. Safety of other drivers on the road at risk, my life and children’s lives were at risk. Could have caused death had our van been stuck in the middle of this busy intersection a few feet more forward.
