2017 CHRYSLER PACIFICA Power Train 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

After purchasing a used 2017 Chrysler Pacifica from Massey Cadillac of Orlando, a warning light appeared during the initial drive indicating a malfunction in the Auto Start/Stop system (capital letter “A” inside a circle with an exclamation point). The system was disabled and indicated service was required. The vehicle was inspected by an authorized Chrysler dealership, which confirmed that the auxiliary ESS (Engine Stop/Start) battery was missing, not failed. Installation of the auxiliary battery and associated mounting hardware was required, indicating the component was not present in the vehicle at the time of inspection. The auxiliary ESS battery is part of a safety-related system. The servicing dealership advised that operating the vehicle without this battery can result in intermittent loss of power steering assist and potential loss of motive power without warning, increasing the risk of a crash. The condition was confirmed by an authorized dealer and is available for...

Vehicle was purchased with 95,xxx miles. Within 10 days sporadic transmission jerks and stalls started. Taken to repair facility 3 times over next 2 months with no issues found. During long distance trip transmission felt rough and sluggish. Transmission was serviced. Engine light on. Repair facility replaced all spark plugs, coil packs and cleared codes. 2 weeks later light came back on. Transmission still not functioning properly. Repair facility called Chrysler specialist technician in and no issues found. Engine codes cleared. Engine light came on next day. Repeatedly faulting for cam response slow. Repair facility replaced lifters and rockers in cylinder 6. All cam sensors and solenoids replaced. Engine light stayed off for 3 weeks. A RECORD. Light back on but no issues found during 3 hour test scan. Transmission still shutters, jerks and stalls. Total “repairs” $68xx.xx and over 28 days out of service. Vehicle now has 128,xxx miles...

I am reporting a serious safety issue with my 2017 Chrysler Pacifica, purchased in February 2024. The vehicle experiences repeated drivetrain shutdowns and unsafe operation due to confirmed failures in the transmission control module and valve body, diagnosed by Chrysler Dodge Jeep in North Las Vegas, Nevada. These malfunctions prevent proper gear engagement while driving, creating a significant risk to myself, my five children, and others on the road. Multiple dashboard warnings—including “Service Electronic Stability Control,” “Park Sense Unavailable,” “Park Brake Temporarily Unavailable,” “Blindspot Alert Temporarily Unavailable,” “Service Trance Stop Safety Shut Off Engine to Engage Park,” and “Accessible Cruise Control Unavailable”—have appeared intermittently since purchase. Dealer inspections and diagnostic reports confirm the problem, but repair costs exceed the vehicle’s value, leaving the issue unresolved. This ongoing safety hazard requires immediate investigation to prevent potential harm to passengers and other drivers.

The contact owns a 2017 Chrysler Pacifica. The contact stated that while driving 60 MPH, the message “Service Rack and Pinion Gears” was displayed. The contact stated that it was difficult to turn the steering wheel to the left or right. The contact was able to drive the vehicle to an independent mechanic. The mechanic diagnosed the vehicle and replaced the rack and pinion gears and the steering module. The vehicle was repaired; however, after the repair to the steering, the contact experienced a failure with the transmission. The contact stated that while stopped at traffic signals, after depressing the accelerator pedal, the vehicle failed to respond. The contact stated that several unknown warning lights were illuminated. The contact stated that the engine was running but was vibrating roughly, and then the vehicle jolted forward. The contact stated that the failure was intermittent at first but had become a recurring...

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

I had the recall for 73B performed in mid October to my 2017 EV/Hybrid Pacifica- 2017 and only 67K miles. No issues before. Since the recall service I’ve brought it in twice with the same problems stating Hybrid Battery needs conditioning/service. I suspect it’s the recall update that has caused all types of issues. I did go to auto zone before I brought the vehicle in just this Monday to get the codes. U0412, P1A29, P0A7F- invalid Data received from Battery energy control Module A - Lost communication with Hybrid Battery Pack Sensor Module- A Deterioration. If you google 73B recall service problems on Chrysler Pacifica - the following appears: Failure to charge and engine light: Some owners have reported that the vehicle no longer charges after the recall service and has a check engine light, with error codes like P0A0A (High Voltage System Interlock Circuit) and P0A7F (Hybrid/EV Battery...

My 2017 Chrysler Pacifica Touring-L has suffered repeated and dangerous electrical failures since purchase. Shortly after buying it from AutoNation Chrysler Dodge Jeep RAM in Valencia, CA, I had to return it twice for electrical repairs that kept it in service several weeks under warranty. About two years later, while still under extended warranty, the engine underwent a complete rebuild for multiple-cylinder misfire codes that were likely caused by intermittent CAN-bus voltage loss rather than a mechanical defect. Over the past nine months, the vehicle has again developed severe electrical faults while driving: sudden loss of power steering assist, all dashboard lights illuminating, windshield wipers activating spontaneously, and the engine failing to shut off using the Start/Stop button. The vehicle has also stalled without warning while driving in traffic or idling at red lights, restarting only after 5–10 minutes and blocking traffic lanes, placing me and surrounding drivers at significant...

This van has a factory defect of the engine. These engines have known issues with blowing head gaskets and Chrysler doesn't seem to care. There are hundreds and hundreds of reports of this issue and these are just the people online talking about it. I am sure there are thousands more. https://www.pacificaforums.com/threads/2017-pacifica-engine-failure-owners-list.52928/page-19?post_id=723158&nested_view=1#post-723158

Backup camera - blue screen or black screen. This has been reported several times and was recalled for the 2021-2023 Pacifica. This is dangerous. The transmission jerks really hard between 2-3 great which has also been reported as a normal occurrence that Chrysler has not addresses.

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 transmission in our 2017 Chrysler Pacifica has had issues with slipping, or not engaging as well as violent, hard gear shifts for at least the last 40K miles. We have taken it to the dealership several times, but the dealership said they drove the van and could not replicate the issues. It is important to note that the issues are intermittent and there is no obvious reason why it happens sometimes and not others. There have been countless instances where the van starts rolling forward from a stop and effectively slips into a neutral position before hard shifting back into gear and moving forward. Sometimes when pressing the accelerator at a dead stop the engine revs up before the transmission engages and starts to move forward. Both of these issues create serious risk of being in the middle of an intersection when this happens as the slipping is most...

The contact owns a 2017 Chrysler Pacifica. The contact stated that while driving at an undisclosed speed, the gear shifter independently shifted into park, and the service shifter error message was displayed. In addition, the contact stated that the odometer reading was incorrect. The contact stated that the odometer reading showed more mileage than the actual trip mileage. The vehicle was taken to the dealer; however, the failure was not duplicated. The contact stated that the failure was persistent. In addition, the contact stated that the failure almost caused a crash while children were seated in the vehicle. The manufacturer was not made aware of the failure. The failure mileage was unknown.

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.

Transmission will have a very severe jerk when starting out, usually at low speeds, causing the driver to temporarily lose control and distract them from driving. This appears to be a very common issue on the recent model Pacifica that uses the ZF transmission. There is a serious disagreement about the servicing interval of the oil in the transmissions. Chrysler states that it is a "Lifetime" oil and does not require changing. The transmission manufacturer ZF, states on their website that it must be changed at 100,000 Km. Some Chrysler dealers say it needs periodic changing, while others say it never needs changing. The impact of this is that a significant number of transmissions are failing. When these are in warranty, they are replaced by the dealer, but those out of warranty result in a major expense to the owners, even though the owners are following the auto manufacturer's recommendations....

When driving van will jerk or bang like slipping in gear, feels like possible being hit from behind, we have tried the adaptive learning reset several times, we had just purchased this less than 2 months ago with about 4800 miles in it. Feels dangerous to drive, especially with kids. We are scared to even try the cruise control. We heard and read online many whey same issues, with warranty and having there vans in dealership on several events, having reset in software upgrades, transmission replacement with only the problem to return. Please fix this, this one of my vehicles that unfortunately I have to drive because it's my only vehicle. This problem happens at lest everytime I'm driving daily, it started maybe a few weeks ago from the time this has been written.

Engine lost power and shut down and would not restart. Engine has had continued issues for close to a year.

Although no active recalls are on the now. While driving the transmission changes hard. It makes a loud noise and jerks randomly. I’m concerned it wasn’t fixed during recall. I recently purchased this vehicle used. Do I have any recourse?

My 2017 Chrysler Pacifica hybrid has been at the Chrysler dealership since December 5th of 2024 for recall 73b and dtc p0c78 The dealership attempted to perform recall 73B but unfortunately were not able to because the hybrid battery would not accept a charge.(During the recall you have to fully charge the battery and then discharge it to test the battery) The dealership has gone back and forth with the recall team and a Chrysler engineer they finally gave me the news today that they will not be covering the battery, even though the battery is to be replaced if the battery is seen to be faulty they want to charge me $24,000 to replace the battery, I truly feel like Chrysler is not wanting to honor the recall and do what they should by replacing the battery I have spent thousands of dollars on this vehicle with parts that...

Hi! This vehicle stopped twice in the middle of a road on its own. Vehicle was driving fine and the next second it slowed down and wouldn’t accelerate as I would push the gas pedal. It’s as if the engine shut down due to the car signals not transmitting correctly. The screen started blinking on and off giving me warnings and one of them said “Service Shifter!” My safety and my children’s safety was put at risk because anyone could’ve hit us from behind as the car started decelerating on the road with oncoming traffic. I towed the car to a mechanic as the car does not run properly while being driven, and the mechanic said it has multiple electrical issues and multiple leaks. The vehicle was inspected by my own mechanic, as the dealer also inspected it and they tried to connect the scanner to turn off the engine...

Power steering module malfunctioned when taking kids to school. Auto repair shop confirmed.

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 -

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.

Unknown

The transmission shifts very hard, it causes the vehicle to jump forward and feels like you have been hit by another car. There is not one specific incident it happens frequently

Misfire cylinder 3 caused by head gasket failure. Known issue in Chrysler Penstar engines and they are not taking responsibility. Could have been stranded in middle of highway if I didn't get off the road

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.

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...

44,000 miles- engine shake and check engine light on. Dealership changed spark plugs as the issue. Spark plugs not even recommended to change till 100K miles Spring 2024- Active shutter grill replaced Fall 2024 92,000 miles- code Misfire Cyl 3 replaced spark plug and coil. Code came back a few days later. took to Dealership and head (Cyl 1,3,5) replaced. Dealership advised that they repair many engine heads

The contact owns a 2017 Chrysler Pacifica. The contact stated the gear shift was in reverse however the vehicle went forward independently. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 115,000.

Shifter assembly. Turned on Pacifica engine. The battery was also reading 14.2 and normally it's at 13. The steering wheel button light was on, and it turned on by itself. The shifter assembly light was off and wouldn't allow to go into gear. The check engine light turned on and the service shifter was on the screen. When I pushed the button to turn off the steering wheel button the engine started to vigorously rattle and the rpms were jumping all around. Towed it to dealership and they said the shifter assembly is failing but hasn't completely failed. This issue has happened 3 times.

Minivan was performing normally, then at a signal light after 14 min of driving on the hwy, the car stalled at a major intersection. Multiple attempts were made to restart but gear selector was locked in drive. The knob would not turn (locked). Multiple Error messages were displayed on central gauges and tow truck had to be called, since car was blocking freeway lane crossing. The car did restart eventually but gear selector still locked and minivan is not operational.

Our 2017 Pacifica has been in for diagnostic review/repair several times. While traveling between speeds of 50-70 miles per hour after a period of anywhere between 35-90 minutes when making easy right corners the steering sticks in place between 11 & 1 positions. Has been noticed on shorter distances in hotter weather than and on longer trips farther into the drive. We recently had the electronic power steering computer replaced which did not fix the problem. Currently the dealership is advising that the rack and pinion need replacing but the warranty company will not pay as they are not able to replicate the error in the presence of the warranty company inspector. Since replacing the electronic power steering was unsuccessful in correcting the problem, the warranty company is requiring the dealership to provide proof of part failure before they pay. My son turned [XXX] on [XXX] and got his drivers...

I purchased my 2017 in 2023. Within a few months, problems began. When we brought the van back to the Chrysler dealer to have it checked with their OBD2 code reader, multiple codes pulled up… First thing “needing” to be replaced was the hood sensor because the display said the hood was open (even though I was simply stopped at a red light). The auto start/stop light was also coming on and staying on. The dealer said that would go away after replacing the sensor. That repair was done (I believe) in April of 2024 at the Chrysler dealer (and the auto start/stop light came back on a week later, both batteries testing fine independently of one another). Next thing “needing” to be replaced was the accelerator pedal module because my van would start shaking, not accelerate, and go into (what I now know is) limp mode with all warning...

The contact was able to drive to the residence. The vehicle was not diagnosed or...

Cylinder head damage at 101,000 miles. Valve guides and seals degraded to where it misfires. Problem confirmed via code scanner and leak-down test with a local mechanic.

I was pulling into a parking lot and had my foot on the gas. The gas pedal suddenly stopped allowing me to accelerate. The dashboard read "place car in park" I lost power of the vehicle. I was able to pull safely into a parking space and then I put the van in park and turned it off. I started it up and it started without issue. This was a very scary situation as I almost hit a shopping cart where I was forced to pull in as I had no power and was coasting in a parking lot full of cars.

The contact owns a 2017 Chrysler Pacifica. The contact stated that while depressing the accelerator pedal, the vehicle would not immediately accelerate, and the transmission experienced hard shifting. The check engine warning light remained illuminated. The contact stated that later while driving at an undisclosed speed, the engine misfired. The vehicle was diagnosed, and it was determined that the transmission was faulty and engine coolant was present inside cylinders number 1,3 and 5. The vehicle was not yet repaired. Additionally, the driver’s and passenger’s side sliding doors malfunctioned and erroneously opened after being closed. The doors were reprogrammed, and the vehicle was repaired. The contact stated that after a cold start the brake pedal extended to the floor. The cause of the failure was not yet determined. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 40,000.

Blown head gasket at 64000 miles. Leaking coolant into the cylinders. Mechanic says the gasket has been repaired before.

Multiple events (over 5) have occured from December 2023 thru March 2024 involving the transmission clunk/jerk/bang with near total loss of speed when accelerating from a stop or low speed. Also several events with loss of acceleration (no reponse from the gas pedel). This happened with me turning left at a light and trying to clear an intersection. Van is available for inspection. Safety was put at risk by van stopping in moving traffic, and with being nearly rear ended several times. Also nearly being hit head on by not being able to complete the left hand turn thru the interesction timely. Vehicle has not been inspected by any dealer or law enforcement. There have never been any warning light given during these events. Dealer said by phone that without warning lights they would have nothing to trace the problem with. I have listed only the last event time below...

44110 miles. NO leaks, oil change every 2500 miles, all fluids are full and well maintained. Hard shift sometimes while in drive and accelerating. Engine light just came on yesterday with wife and 4 kids in vehicle, then engine light flashing. Pacifica felt sluggish and engine was rough. This happened driving on busy FREEWAY! Quickly pulled over at off ramp. Called tow and Mechanic neighbor pulled trouble code from ODB port using scanner P0306 which is engine misfire in cylinder 6. Car runs like crap and is unsafe to drive. Now need to tow to dealer for very expensive repair, just outside of 5 year warranty.

I purchased this Chrysler Pacifica from advantage auto sales in new Kensington pa. Making payments obviously but I have had nothing but issues since we got it.
