2017 CHRYSLER PACIFICA Electrical System 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.

The contact owns a 2017 Chrysler Pacifica. The contact stated that while driving approximately 30 MPH, the steering wheel became difficult to turn to the left or right before the vehicle stalled. The steering assist warning light was illuminated. The vehicle was pulled over and restart and driven to the residence. The vehicle was not taken to a local dealer or independent mechanic to be diagnosed or repaired. Prior to the failures, the vehicle was difficult to start while cold-starting. The contact researched online and related the failure to NHTSA Campaign Number: 19V348000 (Electrical System); however, the VIN was not included in the recall. The manufacturer was not informed of the failure. The failure mileage was approximately 125,000.

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...

We purchased the vehicle in 2020 with appx 33,000 miles. In fall 2023- winter 2024 it began having electrical glitches when the weather was cold. The car will start, but will not shift into gear. It throws alarms such as service Parking Brake, Shifter, Engine, Traction Control and that you must put it in Park. Although it obviously is in park or it wouldn't have started. The dealership kept it for a month Nov-Dec 2023 and could not get it to recreate the problem, but replaced the battery since it "failed". We went on vacation for Christmas and had issues with it not shifting after it sat all night in the cold. However, the problem is intermittent. But the cold seems to be the consistent factor. Once the weather warms up, it does fine. Although 1 time in sumer 2024 with very high temps 100+ it threw the same alarms...

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.

This is a complaint regarding an inadequate recall remedy for Recall Z75 (NHTSA 24V-538). The manufacturer's software update rendered my 2017 Pacifica Hybrid inoperable due to DTC P0C77. While the battery was ultimately replaced under warranty, the manufacturer is refusing to reimburse $1,948.74 in rental expenses despite a prior verbal commitment to do so. This constitutes a failure to provide a 'free and effective remedy' as required by federal law for safety recalls.

We bought this vehicle from a local dealer in March (9months ago) in the time we’ve had it… it’s been in the shop for about 6 of them. 1- About 3 weeks after the purchase it shut off while I was driving on the highway. We then took it to the dealership in Jasper, Ga bc the error code said the pcm needed to be reset. They couldn’t get it to reset so they embarked on a diagnostic that took 3 months to discover the fuel pump was “too small”. The dealership repair guy assured us this was a solve to the issue, they’re tech put 200 miles on it an had no issues. 2- The day we got it back the check engine light came on and while going around a curve to the right, the wheel locked up on me and almost drove me into a mailbox. We...

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...

I have been driving, usually at lower speeds and the entire electrical system shuts down. This has left me and my children in the middle of a busy road without brake lights. It has happened multiple times. The battery will be dead and charge multiple times, but then I end up having the electrical failure. It is terrifying. I had the battery checked and it is not the issue. I have not contacted the dealership, but plan on it tomorrow.

Despite repairing multiple things on the vehicle, the automatic engine start/stop continues to malfunction.

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...

My 2017 Chrysler Pacifica is shutting off while driving need to be repaired

My 2017 Chrysler Pacifica shuts down while in driving

My car keeps draining my battery. Just bought brand new batteries from Less Schwab and they are both failed! The auto shop did a draw test and says the car isn't drawing power. But it's drawing power somewhere. I found 2 videos saying there's issues with the sliding door wiring corroding? Still working snd causing issues. So I'm going to test it out myself. Super frustrating. Had to buy new batteries as soon as I bought from the dealership last year and now those batteries are dead!

When turning to the right, around 35-45mph on a sharp turn, the steering will stick. Yesterday the sticking was so bad it almost caused me to lose control in the middle of the curb. It does not stick when taking sharp turns to the left. The mechanic has not been able to locate the issue.

The vehicle will randomly shut itself off while it is operating causing the dashboard to flicker on and off before shutting down fully. The steering wheel gets stuck at the 1:00 position.

The electric steering has a stiff jerk at random positions when taking a turn. It seems to happen at the 11 o clock and the 1 o clock positions on the wheel. It causes a stiffness when driving on a turn that causes myself to have to jerk the wheel to get it out of the stuck position, which causes the vehicle to jerk and causes panic. It seems to happen every time I drive the van, several times during a trip, basically every time I take a basic turn. The safety of my family is put at risk because it causes me to have to jerk the wheel to get the steering under control. This is a current on going investigation. There are no warning messages or lights on for this. Please investigate this and get this issue fixed. It’s scary and dangerous to my family and others on...

Engine ticking,blind spot not working

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

The contact owns a 2017 Chrysler Pacifica. The contact stated that while driving at slow speeds, the vehicle stalled with the message "Service Now” flashing on the instrument panel. After waiting for approximately 15-30 minutes, the vehicle was restarted and resumed normal operation. The vehicle was taken to an independent mechanic, and it was discovered that the oil filter adapter was cracked, contributing to the failure. Upon investigation, the contact linked the failure to NHTSA Campaign Number: 18V049000 (Electrical System, Engine and Engine Cooling). The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 90,000.

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

- digital display not working when in reverse; yes it is available upon request - unable to see behind the vehicle properly impacting safety of everyone in vehicle. - dealership confirmed there is a recall for this issue but our VIN is not included yet. - no inspection yet. - no; 6/6/2025

I own a 2017 Chrysler Pacifica Hybrid that is currently under active recall and within the 8-year federal hybrid warranty. My vehicle is covered under Recall 20V334 (W46). The high-voltage (HV) battery has failed, rendering the vehicle undriveable. The dealership confirmed the battery needs to be replaced and opened a warranty claim, but they do not have parts available. Despite this, Chrysler has refused to provide me with a rental or loaner vehicle while the car is awaiting repair — citing that my vehicle is “not a 2019 or newer.” I was also denied escalation to a supervisor by Chrysler’s customer care team, even after I requested further review. This leaves me and my family without safe, reliable transportation. Chrysler’s refusal to provide a rental violates the intent of the recall process, which is to protect drivers and passengers from unsafe conditions. The car cannot be driven, and there is...

After driving, I can to a stop to park the van. The van would not shift to park and instead would go to neutral. I then could not turn the van off. It would only stay in accessory mode. Upon looking at this issue online, many Chrysler Pacifica owners have the same issue. Some people are able to fix the issue easily, while others needed to replace the transmission valve body. This is an incredibly expensive repair. There were no warning lights ahead of this problem happening, it happened out of the blue. No codes are shown when reading for codes in the van. The message that pops up when the van would not shift to park was “service trans press brake when stopped key off engine to engage park”. But the van will not turn off completely. To get the van to shut off, the battery needs to be...

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...

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...

UNEXPECTED ENGINE SHUTDOWN ALL POWER STOPPED WHILE DRIVING.

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

grille shudder broke

I am writing to report another incident related to my 2017 Chrysler Pacifica. Today, while driving on a major highway, my vehicle unexpectedly shut off and braked violently multiple times without warning, creating a serious safety hazard. Fortunately, there was no accident, but due to the sudden and forceful braking, I am now experiencing pain in my head, neck, upper back, and shoulders. I previously reported electrical issues with this vehicle on January 22, 2024. Given the recurring nature of these problems, I am extremely concerned about the ongoing safety risks. Please advise on the next steps to formally document this incident and any updates regarding similar reports or investigations into this issue. I appreciate your prompt attention to this matter and look forward to your response.

Sometimes when the car starts, the lights on the gear shift won’t light up, and you cannot put the car into drive or any other gear. Seems to be related to the electrical box inside of the glove compartment. Have seen videos of other drivers that have noticed the same issue.

The manufacturer was not notified of the failure. The failure mileage was approximately 105,000.

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

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

The contact owns a 2017 Chrysler Pacifica. The contact stated while driving at various speeds, the vehicle lost automotive power and failed to accelerate above 5 MPH. During the failure, several unknown warning lights were illuminated. After turning off and restarting the vehicle, the failure self-corrected and the vehicle operated normally. The vehicle was taken to the local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was notified of the failure.

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...

Problem 1. Service airbag light. We bought our brand new 2017 Pacifica the summer of 2017. Within a month, we took the van in to the dealership due to the service airbag light. They told us they couldn’t replicate the issue so they couldn’t fix the issue. The van has been having the same issue for the past 7 years, the service airbag light randomly popped on especially in the summer/winter when hitting a bumper or making a sharp turn. We took the van in numerous times but they couldn’t detect any issue or read any code due to it. Recently months, it has happened a lot more often, finally we are notified the issue was due to the faulty occupant restrain module which could cause the airbag not to deployed during an accident or to deploy during a normal driving. Problem 2. U0001 Can bus issue. The check engine...

Numerous issues: 1. Multiple misfire codes, check engine 2. Loss of Coolant, no indication of leaks 3. Faulty thermostat. Loss of A/C and heat 4. Bottom of both sliding door panels corroded, with paint loss 5. Uconnect system malfunctioned, not working at all **Repairs have costs thousands already. And based on the other complaints, probably much, much more. Something is obviously wrong here, but Chrysler is NOT doing much about it unfortunately.

The contact owns a 2017 Chrysler Pacifica. The contact stated that while children were attempting to exit the vehicle from the rear driver’s side sliding door, the door failed to open as needed. The contact attempted to manually open the door from outside the vehicle and was unable to open the door. The contact stated that while driving to the dealer to service the door, the door ajar message was displayed on the instrument panel, accompanied by a warning chime. The contact closed the door which corrected the failure. Once the vehicle was at the dealer, the failure was diagnosed, and the contact was provided an estimate for the repair. Upon investigation, the contact discovered Manufacturer Communication Number: 08-027-18(Electrical System) which was linked to the failure. The manufacturer was notified of the failure but offered no assistance. The vehicle had been repaired. The failure mileage was approximately 40,000.

I was driving, slowing down approaching stop sign and the car just shut off leaving me stranded in the middle of a road, blocking traffic. It is a start/stop push button so there was no way to get it in gear to move it. Everything was completely locked up. I had my child in my car with me. If we had been 10 minutes further into my trip, I would have been on the highway and we probably would have been killed as a result of the car just shutting off. I had to have it towed and am waiting to hear what the repair shop finds but they are expecting an electrical short. I see this is a problem with the hybrids of the same time period. I think you need to investigate the non-hybrid cars as well.

The vehicle presents almost all warning lights then acts very radically . The engine will stall, won’t go in gear . It will happen while vehicle is in motion. Super dangerous. I’ve had it to the dealer 3 times . They can’t seem to find a fix

Intermittently my van will lose power, all dash lights will pop up, active parksense unavailable, service required , blind spot alert temporarily unavailable , service shifter, fcw unavailable service required, service electronic stability control will pop up on the dash and in the message center. Code p0420 has popped up on a reader. Several trips to the dealership purchased at, and they cannot figure out the issues. I have 2 kids, this is a major safety concern. I had it shutdown on a highway 3 weeks ago with my 9 month old in the van. Recall list says everything was repaired, but it seems there needs to be more recalls. These vans are not safe. Recall them all. Chrysler is going to end up with a lawsuit. I think this is a major defect on the electrical and computer systems. When driving the van it will show I'm doing 70...

The contact owns a 2017 Chrysler Pacifica. While the contact's wife was driving at an undisclosed speed through an intersection, the automatic braking system engaged independently, and the engine shut off. Despite the sudden failure, the contact's wife was able to restart the vehicle and resume normal driving. The contact then stated that while driving at slow speeds, the failure reoccurred with the Lane Departure Assist message flashing on the instrument panel. The manufacturer was notified after each failure had occurred; however, the contact was not offered any assistance. The vehicle was not diagnosed or repaired. The failure mileage was approximately 67,950.

I was driving my car and approached at a stop sign. The car stopped and froze. The shifter knob lights were out and I was unable to move the car or shift the gears into neutral . ( The engine turned on ,but I could not move my car.) I had the car towed to my autodealership. Since then, the car has repeatedly started, but the shifter is frozen. My dealership has spent a month telling me they don't know how to fix the car. The dealership has been trying one thing after the other, they tell me, yet within a week my car is not functioning. The dealership installed new programming. a week ago.. A few days afterwards, while I was slowing down in city traffic, the dashboard filled with error messages and the car became extremely bumpy to drive. Today, I just had the car towed again to...
