Electrical System Problems of Chrysler Pacifica - part 1

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 turned around and went right back to the dealership. They had it for another couple weeks and told us we needed a new rack and pinion. We couldn’t afford the $6000 they wanted to fix that. So we then called the guy we bought it from and he had a local repair shop take a look and they replaced some parts on the rack and said it was good to go. 3- got it back and the check engine came on again, they code said pcm needed to be reset. We couldn’t get the dealership to call us back so we went to the local shop o’reileys recommended and they deducted some gauges needed to be replaced. 4- within a couple weeks the van was sputtering and cutting off again, we took it back to the local shop and the only thing they could think to do was change the auxiliary battery. 5- we’ve had it for about 2 weeks… 2 days again I went to start it up and it cut off. I had to wait a few minutes to try again and it started. Then yesterday while driving we stopped a red light and something popped and the dash lit up with errors and a grinding noise started. We went to accelerate to turn and started rolling backwards while in drive. We slammed on the brakes, turned the cautions on and put it in park and still rolled backwards. We had to get a tow back to the local shop.

Reversing onto roadway and shifted from reverse to drive via rotary dial and vehicle went into park and would not move causing me to block the roadway. In addition and even more concerning was that the vehicle could not be turned off and any and all actions to do so just left the car "on" and the hybrid system running. Eventually we pulled the battery cable on the main 12v in the trunk and the reset allowed us to move the vehicle again. I sat across a busy section for twenty minutes with no way to move, turn off, or overide the system with three kids with me in a busy traffic area. The vehicle has not reproduced the issue as of yet. The dash had multiple warnings for park system and service various items needed. This occurred 12/17/2025 with 70,000 miles.

The contact owns a 2023 Chrysler Pacifica. The contact stated that the hybrid battery became inoperable. The contact stated that the vehicle stalled and failed to exceed 30 mph. Several unknown warning lights were illuminated. The vehicle was taken to the dealer, where it was diagnosed that the hybrid battery had failed and needed to be replaced. The contact was informed that it would take months to obtain the replacement battery. The battery was later replaced, and the vehicle was repaired. In addition, the contact received notification of NHTSA campaign number: 25v302000 (air bags); however, the parts to complete the recall repair were not yet available. The vehicle was taken back to the dealer, where it was not diagnosed or repaired. The dealer confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact had not experienced a failure related to the recall. The failure mileage was not available.

The charging system light came on. My wife went to charge at public charging station due to being close to one. After plugging in the van, it said charging failed. She unplugged the charged went to back up and the van died. Had to have it towed to dealer. Dealer states even though the van is in the warranty period, the idcm which is up under the van is scuffed and therefore isn’t warrantied. They said there is a big dent in the muffler also so we must have ran over something and caused the damage even though we live in a city with paved streets, a subdivision with paved streets, and have a concrete driveway at our home. They said they have sent me emails with the pictures which I have yet to recieve. I went to the dealer and asked them to jack up my van so I can see the damage personally and they don’t have a lift available at the time, so I told them I would be back in town at a certain time from work and to call me so I could see it and they have yet to show me the scuffed idcm module or the dented muffler. We haven’t run over anything to cause this kind of damage to a module like this because all the hybrid batteries are under the van. If the Chrysler Pacifica hybrid is so cheaply made for a $62,000 vehicle that something can “scuff” a module housing and shut a vehicle down, this is potentially very dangerous if someone were driving on the highway if it were to shutdown and someone (including myself or any of my family) were driving and lose all propulsion and steering (because it’s electric steering) or worse braking! it could be catastrophic with people dying. This needs to be investigated to see how fragile this component is and if they need to “toughen” it up or re-locate it. Versus trying to get by and get around paying warranty claims or hoping nothing happens until the units break down after the warranty period not knowing of the safety hazard they have created for their vehicle owners and the driving public.

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.

After safety recall 73b was performed on my 2018 Chrysler Pacifica hybrid on 11/24/25, the vehicle's check engine light illuminated. Code u0412 is identified as a 'stored' code upon pulling obd information. This is described as "invalid data received from battery energy control module 'a'" indicating failure of the high voltage battery pack and its control system. The hv battery is available for inspection upon request. My safety and the safety of others are at risk because the recall was issued to prevent a battery fire. The symptoms my vehicle is exhibiting are precisely the kinds of faults the recall's software update is supposed to detect. The check engine light, appeared within days of the recall service. This strongly indicates the recall procedure, specifically the mandatory battery integrity test, was not completed correctly, and/or that there is a failure in the underlying recall procedure itself. This is a widespread issue, with numerous owners reporting the same post-recall failures to their dealership, online, and to Chrysler cares customer service without satisfactory resolution.

While driving down the highway at 70 miles per hour ater driving 2. 5 hours our 2021 Pacifica hybrid minivan flashed a warning on the vehicles display saying approximately "warning engine shutting down". The engine immediately shut down in the middle of the highway and we were forced to coast off the highway to the shoulder. The engine warning light came on. We turned the car off for a few minutes and proceeded to start the engine. The engine warning light was still on, but the other message was gone. We attempted to drive towards our destination and approximately 30 minutes later the same thing happened again. We tried one more time since we were several hours from home and within 30 minutes the vehicle had the same issue. At that point we decided to try to get home. We drove the vehicle 15-20 mins at a time and then exited the highway over and over giving the vehicle time turned off. After returning home with no additional events the engine warning light went off the next warning. This was on a Sunday so we were unable to get it to a dealer. The next day we dropped off the vehicle at nappletom Chrysler dealership. The called us the next day and told us they could not cause the event to happen again. They could see a set of error codes showing the problem occurred, but told us there was nothing they could do and it was up to us to cause the problem and then return the vehicle. Now I have a minivan with 70k miles on it that my wife primarily uses my with to get my daughter from place to place and I have no idea when this vehicle will shut the engine down at any time potentially causing a dangerous accident. I believe Chrysler has the responsibility to determine what the issue is. Researching on the internet show this is a common problem for my vehicle and typically requires a new transmission or and engine wiring short.

I purchased this van in March 2025, it was used about 62000 miles, but dealer said it was in good condition, no issues. In September 2025, a battery light came on, that also activated the start/stop could not be used and needed service as well as service shifter. I brought the vehicle in and they simply replaced the auxiliary battery and sent me on my way. On November 13th, I was driving and a battery light came on as well as the stop/start not available error, and then moments later said "stop safely vehicle will shut off soon". Thankfully I was only moments from home, and made it safely with my 5 children who were also in the van. Obviously this is dangerous as the vehicle stopping while driving can kill myself, my children, anyone in my vehicle, as well as cars around me as I live in a busy area, tampa, FL. This car had just been given a review in March when put up for sale, and I had brought it in for an oil change, as well as a motor mount replacement, and the aux battery change, before this. My car has been serviced multiple times and this should have been checked or errors/updates reviewed. This auto/stop start seems to be a key in the safety issues as well since that light comes on every time there is an issue. Now the dealer states they are going to replace my pdc, main fuse box, and see if that fixes the error, but I have read that this is an error in many Chrysler Pacificas and mine is another.

Vehicle was put into reverse and did not stop, it hit a pole. Then the driver tried to put in drive to get it off of the pole and it accelerated quickly and the driver could not stop the vehicle. There was little time to react as it hit the side of a building and airbags deployed. Driver stated that the car accelerated on it's own once it was put into gear.

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.

My 12v battery failed and damaged other system components. This is a description of the flaw from a mechanic that had the same problem: there is a major flaw in the Chrysler Pacifica hybrid. The bpcm (high-voltage battery control unit) has no protection against high-voltage pulses on the 12-volt network. Moreover, the connection diagram of the high-voltage contactors does not contain any elements that could extinguish the counter-induction emf pulses when the contactors are turned off. That is, when turned off, the contactors in the 12-volt network create high-voltage surges that can burn anything, any block that is connected to the 12-volt network. In my case, the power supply module of the high-voltage battery control unit bpcm was burned. The lg chem battery modules themselves were in perfect order during this malfunction. The circuit of this module is quite complex, the board is multilayered and it was difficult for me to repair it. I have a sloped driveway, and the failure led to my car starting to roll uncontrollably forward into my house. I was luckily able to stop it by throwing blocks under the tires while my wife held down the breaks. When I (or my wife) let go of the powerless vehicle's breaks, it would continue to roll as the power failure prevented the vehicle from either entering park or engaging the emergency break. We barely avoided significant property damage.

Component/system: the propulsion system of my 2020 Chrysler Pacifica hybrid, specifically a suspected internal transmission wiring-connector short—the exact hardware defect identified in recall 23v-010 as capable of causing sudden loss of motive power. In my case, both propulsion sources (gas and electric) simultaneously ceased providing power, leaving the vehicle unable to accelerate. The vehicle, its transmission, and all hybrid-system components are available for inspection upon request. When inspected at the Chrysler dealership, technicians retrieved a diagnostic trouble code they acknowledged corresponds to the known wiring-connector short condition. This code was present before any recall procedures were performed. Safety risk: I was traveling at highway speed with my family, the vehicle abruptly lost all motive power and began decelerating without my ability to maintain speed. I was forced to coast to the shoulder while surrounded by faster-moving traffic, exposing me and other motorists to the danger of a high-speed rear-end collision. Dealer confirmation: the Chrysler dealer confirmed the presence of the wiring-connector-related fault code and agreed that it aligned with the recall defect pattern. However, they performed only the software update required under recall 23v-010 and informed me that they would not undertake further inspection or physical diagnosis unless I paid out-of-pocket, despite the safety-critical nature of the failure. They are ignoring the fact that the physical underlying defect is not fixed by the software update, much to my frustration. With this unfixed, the car is not safe to drive imo. Inspection: the vehicle has been inspected by an authorized Chrysler dealer. No additional parties have inspected it. The dealer did not examine or repair the wiring harness or connector itself, refusing my request to do so. Warnings/symptoms: a hybrid/electrical-system warning message appeared moments before the shutdown. No prior symptoms.

When I tried to start my Pacifica I got a clicking sound like the battery was almost dead. I tried again and a very loud pop came from the area above the driver side around the top left windshield or possibly the air bag area. All the electric doors failed to operate. The car did not start. I snapped pictures of the instrument cluster. The motor led came on, the "auto park not engaged" came on. The engine start button showed run. All 5 gear shifter led were on "p r n d l". Both outside mirror blind spot indicators were on. I was trying to go to a doctor's appointment so I tried lifting the battery cable under the hood to reboot the computer. That worked and all returned to to normal. This malfunction has happened twice in the past month. The second one happened 11/4/2025. Photographed images are available upon request.

Engine shutdowns randomly while driving and it almost caused me to crash once on the highway and the other was while in my neighborhood to take my daughter to school.

At a stoplight the fcw ( forward, collision), warning dash light went on and engaged the brakes, thankfully, no movement was taking place. I had to put the car in park and then drive to be able to resume. This indicates that it could have occurred at high speeds, potentially causing a collision.

Power steering impaired while going about 35-40 mph around gentle curves. Carplay will no longer work with the usb port wired to phone.

After taking my car in for the recall on the battery which required a system update, I’ve had multiple errors that the Chrysler service department cannot resolve. Four times in the last two weeks when I get in the car and crank it, it will not go into drive or the shifter does not work at all. I’m having multiple errors on saying service shifter and service electrical battery that had never occurred before the system recall update. I’ve been stranded multiple times in the last two weeks. It must be related to the recall update that was done in my car. It cannot be a sheer coincidence that I never had issues until the update. The service department is not helpful in anyway and returns my car with no answer. Simple google research shows this is a recurring issue after the update.

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 risk. Two major repairs in the last two weeks failed to resolve the defects: (1) repair of the can-bus system after the vehicle would not start and acted erratically while driving, and a week later (2) replacement of the brake-booster vacuum pump, which was shorted internally and caused can-bus shutdown, complete steering loss, sudden braking, and no engine power. The vehicle is currently at dependable Chrysler Dodge Jeep ram, canoga park, CA, awaiting further diagnosis despite repeated repair attempts. These symptoms match Chrysler tsbs 08-007-17 and 08-033-21 concerning body control module water intrusion and communication faults. This ongoing electrical defect has caused steering loss, random stalling, ignition failure, and unpredictable vehicle behavior—issues widely reported by Pacifica owners. It poses a serious safety hazard and warrants immediate investigation and recall.

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 pack deterioration), says reddit users. Intermittent check engine light: other owners have noted the check engine light comes on intermittently after the recall service, sometimes disappearing on its own. Battery concerns: some owners who already had issues with the battery before the recall now report that the recall service did not resolve their problems, and a new, more significant battery issue may have developed. It appears that the issue with the hybrid battery is not being resolved and the service recall for 73b amplifies issues for the hybrid Pacifica models. It may be a ploy from Chrysler for owners to get “rid,” of our vans. I’m contacting the lawyers of the class action lawsuit with this information. It’s so unreasonable for Chrysler to do this and not offer further support. The time, stress, anxiety and loss of a proper running vehicle has really impacted my family.

Rear view camera will not come on in reverse. All fuses are good with no visible damage to wires. Head unit was factory reset with no resolve.

While driving, the Pacifica lost all engine power in the middle of an intersection while traveling at 34 mph. All the dash lights blinked and sounded alerts. The car then showed u1267 and u0416 diagnostic codes.

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

My 2017 Chrysler Pacifica shuts down while in driving.

During normal driving from office to home car suddenly started stuttering and I was apply break but speeded up and showed engine light on, I was about to hit front car due to additional speed. During that time I saw few quick messages on the dashboard, the one that I can remember was related with acc. That's the dangerous situation. I looked d from obd and found that code was u0412 and reported that code to huntington beach Chrysler service station. Please keep an eye out for some similarities between others reports.

The batteries died and we didn't know that there was an ibs(internal battery sensor). The van started to take over its own system. It would put itself in park, open the hood, self holding temporarily unavailable, start/stop unavailable, emergency break engaged, and turned it self off while driving!.

I was driving and the van suddenly lost all propulsion. Brakes and steering and dash lights functioned, but there was a red turtle icon and error message about a system failure. The accelerator pedal did nothing at all. I was able to coast off the side of the road to a place to pull over, but that could have been a terrible accident if I lost power like that on I-95 or any other major highway. My husband came and we switch cars (kids, car seats, etc) and he was able to get the van to start after half an hour. It had check engine lights on for things, but the dealer said to bring it in because it was drivable again. Despite brining it in as told, with check engine lights on that they saw, they said they could not reproduce it and couldn't find codes for the check engine light (even though I pulled them from my own obd2 diagnostic plug tool and took photos of the codes) and eventually said I have to take the car back, despite no cause or resolution. These cars have known faulty battery issues and a large number have been replaced already, but Chrysler isn't authorizing dealers to do that unless they can reliably reproduce the failure. Very frustrating to see Chrysler not go the route of other manufacturers who sourced their batteries from the same plant and ended up proactively replacing them for consumers. While Chrysler's many recalls for the hybrid battery system software have probably made it detect faults earlier to try to prevent fires, they are still known to happen, but now in addition to a fire risk, we also have a car that has a much higher chance of just losing power while driving due to over sensitive battery monitoring, or a plain old faulty battery that just isn't faulty 'enough' for Chrysler to authorize a replacement. So frustrating and dangerous.

Vehicle lost all internal communications while driving. During this incident propulsion was lost, turn signals, hazards, power brakes, power steering, all electronics except speedometer failed. I was unable to put indicators on during this incident outting others at risk. It appears hazards and turn signals are can communication which is absolutely insane and a severe design flaw.

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.

On multiple occasions, from 2023-2025 our vehicle has had issues where all the gauges and warning lights go off and vehicle stops and turns off regardless of driving conditions. Recently happened yesterday. The culprit is the can c bus connectors that Chrysler is using. They short out causing the issue and because so many systems codes get tripped after nearly a year of back and forth with dealerships unable to diagnose issue I went to a Pacifica forum where there are 1000s same reported issue. The issue is caused by the cancam bus connectors - specifically under the dashboard in our case, due to Chrysler using zinc based soldering that cannot handle the heatand elements. These solders use to be made out of lead that can handle the elements. We are replacing them for the 2nd time in less than a year after,as mentioned before, my wife and daughter had van completely stop and shutoff in the middle of traffic. This has happened recently every couple days for the last 3 weeks - previous time happened off and on while waiting for answers from dealership for over a year, they cannot recreate issue because it's random and therefore will not chae the issues or listen when I asked to specifically check item. (files uploaded are from video my wife captured).

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

Component failute: first the cruse control would stop working while driving. Then the engine would rive way up while trying to accelerate and not gain much speed, gas mpg dropped. When breaking to stop I had to push the break pedal harder. When the cruse had stopped and I shut the engine off, it was hard to start, and would bump and shake as if it was hitting on 2 cylinders, cruse still would not work. After I made it home, the next time I started it, it was ok, then the last time I parked it the brake will not depress and it will not start. Battery has 12 volts, jumped it anyway break still want depress. Took battery cables off shorted them together , did not help. Break pedal still will not depress.

I am having an issue with the monitor in vehicle. For several months now have and issue with the backup camera some times working and sometimes it doesn't. It will sometimes be gray or black but will show the lane lines but no outside picture. It will also sometimes show the backup camera but it will be froze and does not move with the vehicle. Saturday had and issue where the monitor was ghost touching the buttons on the screen; it was turning the channel and also changing the air conditioner. I had to cut the radio and monitor off so the air would work properly. Was reading online where some people were having this same issue and was saying it was being recalled for software issues, but with my VIN number shows no recalls at all. Just wondering if this is a issue that should be recalled on these vehicles or if there is another reason for it. If it happens again I will surely get pictures or video evidence since there is an option on here for it.

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.

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!.
