Electrical System Problems of Chrysler Pacifica - part 1

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.

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.

The auto start/stop activate at lights when lift off the brake van cuts off and quickly restarts and turn off the lane departure light and sometimes doesn't restart and is hard to restart. Van sometimes cuts off on the middle of intersection and hard to restart.

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.

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!.

After safety recall 73b was performed on my 2018 Chrysler Pacifica hybrid on 08/25/2025, the vehicle's check engine light illuminated on 09/09/2025. I was inundated with multiple failure lights including; check engine, service electronic throttle control, service hybrid electric vehicle system, blind spot alert, and I felt like I lost power steering. I was unsure if the van was safe to drive, but was able to get it to the dealership. They were able to pull multiple codes. Including the one for the check engine light. They decided that the problem was related to the abs control module. They replaced it and the van has been fine so far. It seems these error codes are widespread after performing recall 73b. Many other customers are complaining of the same thing. I believe these errors are from the testing to the high voltage battery, and their 'software fix'. It's not safe to lose your power steering while driving. It's not safe to have multiple error codes continuously going off while operating the car. It's not safe to have a family car that we have been told twice to not park in the garage, charge, or park near a structure. This is their second attempt at 73b, and overall the second fire recall. My van and high voltage battery are definitely available for inspection.

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.

While driving in the carpool lane on the freeway, the vehicle displayed “stop safely. Vehicle will shut off soon” and lost all power. I am pregnant and had four children (ages [xxx] , [xxx] , [xxx] , and [xxx] ) in the vehicle. The outside temperature was over 100°f, and we were two hours from home. The car was completely disabled in heavy traffic, creating an extreme safety risk for my family. After waiting about 15–20 minutes, the vehicle restarted and we were able to continue. A code scan showed p0a78 – drive motor “a” inverter performance. This is a serious safety concern, and I am requesting immediate inspection and repair under warranty. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The vehicle’s electrical or engine system appears to have failed, causing a sudden loss of power while driving. The exact component has not been identified by the dealership or Chrysler, but it may be related to the recall affecting the vehicle’s powertrain control or electrical system. The vehicle is currently at the dealership and available for inspection upon request. The issue has created a serious safety risk. The vehicle has repeatedly lost power and shut off while driving on the highway, including one incident where I was unable to fully pull off the road before it stalled in active traffic. My children were in the vehicle at the time, placing us in immediate danger of being struck by oncoming vehicles. Because the vehicle can stop without warning, it is unsafe to drive and puts both my family and others on the road at risk. The dealership has confirmed the issue and advised that parts are on backorder for at least 10 weeks. They also stated that even once the parts arrive, they are uncertain how to complete the repair, indicating that Chrysler has not yet provided an effective fix. The vehicle has been inspected by the authorized Chrysler dealership multiple times, and the issue has been reported to Chrysler. It has not been inspected by police or insurance representatives. A warning message reading “pull over as the vehicle will stop” appears on the dashboard prior to each failure event. The first occurrence was on June 10, 2025, while driving on the highway to my daughter’s graduation. Since then, the same warning has appeared multiple times before the vehicle shuts off completely. It has been 6 weeks at this point and I have no vehicle. Chrysler has offered rental reimbursement of $60 a day but there is no vehicle that is a 7 passenger like my van that is of this cost. At this time they do not have a timeframe of when the vehicle will be fixed and denied a buyback or replacement.

Vehicle will start but the shifter will work. It threw a check engine light and check hybrid system code. You cannot get the vehicle out of gear and the shifter will not light up. After shutting the vehicle off and on 3 times it erased and acted like it never happened. This is the third time it has happened. What’s bad you can drive somewhere and be stuck there for hours not knowing if you need a tow or it’s going to reset again. Don’t know if something my happen while driving as well.

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.

My van completely shut off, and all lights on the gear shifter stopped working. Yes, it is available for inspection until the gear shifter is replaced, as recommended by the dealership. The van lost power just as I lifted my foot off the brake to proceed into an intersection. This sudden shutdown created a traffic backup behind me and could have put me and others in danger had I entered the intersection. The issue has only occurred once for my husband while driving but has not been officially reproduced or confirmed by a dealer or service center. Yes. I took the van to the dealer, who suggested replacing the battery and the shifter. I replaced the battery and ordered the shifter, but the second failure occurred after the new battery was installed. In addition, I’ve noticed a continuous clicking sound coming from the van after it is turned off, which does not stop for approximately 5 minutes. There were no warning lights or messages before the failure. After the van shut down, the “start assist” light came on, and it did not turn off until about four days after the battery replacement.

Electrical adaptive, cruise control, forward collision warning, and shifter all malfunctioned. It is available for inspection. There was failure to accelerate at an intersection which almost caused vehicle to be rear ended. The error codes have been pulled and shown by o’reillys auto parts. The vehicle is pending inspection by an independent mechanic. The adaptive cruise control the Ford collision, warning and service shifter warning lamps all appeared shortly before this problem occurred.

While driving my vehicle soon after purchase I notice an engine light on along with a huge fan noise from under the hood. Addressed the issue with dealer they diagnosed the car and so called fixed the issue. About a month ago I’m driving the car on a residential street and noticed the car jerking loud fan noise and the whole dashboard light up saying service hybrid service engine and transmission. . Suddenly the engine stops in moving traffic. The vehicle windshield wipers cut on by themselves and the car stayed in park. . Tow the vehicle to the dealer using only a dolly tow truck due to vehicle unable to be placed in neutral. Dealer calls to give update and noted no codes were stored and there is currently no issue with vehicle. . He suggested to keep the vehicle longer to see if the problem returns. I’m afraid the electrical issue that is going on with this hybrid will cost me and my children life one day. This vehicle is not safe to drive and I am stuck in a purchase contract.

Loss of power steering, power cut out while driving. Batteries have to be replaced in less than a years time.

Vehicle often has a "system charging system" error that prevents it from turning on and driving. This happens when the system is not charging.

I was driving and all of a sudden I got a warning to stop that the engine was going to shut off. I got off to the side of the road and it shut down. I had it towed to the garage. The next day they ran tests. The batteries were both new and they tested fine. Alternator tested fine. Since then it’s happened two more times and the dealer is telling me that all the tests are fine. That Chrysler won’t help me because they can’t prove anything is wrong. Even with the pictures of all the codes and alerts. I don’t feel safe driving my kids in this van at all now. But nobody will help me.
