Electrical System Problems of Chrysler Pacifica - part 1

As I was entering [xxx] between [xxx] and [xxx] the check engine light came on and a warning about finding a service charging station. The accelerator then stopped working, the car stalled out and I was unable to drive the vehicle. Thankfully, I was able to navigate the car to the breakdown lane as it decelerated. I then had to get a tow to the dealership. The engine light came on several times over the last few months prior to this incident but the dealership at shoreline Chrysler Jeep Dodge were not able to fit in the car to diagnose the issue. Their negligence led to this dangerous situation. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The car randomly gives a warning on the dashboard in red, with red turtle symbol, to pull over and stop safely. A lot of the time we will be on the highway and can't pull over safely. It happens at any speed. 25, 80, 65, etc. It's been happening since we got the vehicle in 2023 and no dealership understands what the issue is even though there are clearly recall repairs for other same make and model of other years surrounding this 2022 model. They keep saying its keysense but its not locked for speed and that doesnt make sense because it doesnt happen at a high speed only, it happens randomly even in town going slow. They've done the "software update" a fee times, but it's clearly the same problem as the others with the wiring harness. That part needs to be replaced because the patch software fix isn't a solution and its definitely not a safe solution at that.

Description of incident: on February 15, 2026, my 2017 Chrysler Pacifica hybrid experienced three distinct and severe safety system failures involving the electrical system, power seats, and the power sliding door. Power sliding door sensor failure: while my minor son was entering the vehicle, the power sliding door closed on his leg. The pinch sensor failed to detect the obstruction and did not reverse. This resulted in physical bruising and marks on the limb (photographic evidence maintained). Unintended passenger seat motion: while the vehicle was stationary, the front passenger power seat moved forward to its maximum limit without user input. I was seated in the chair at the time and was pinned against the dashboard before I could intervene. Electrical shock: my minor daughter received a perceptible electric shock upon touching the exterior door-handle button to open the sliding door. Components involved: electrical system seats (power) sliding door (power) injuries: yes (soft tissue bruising/marks to minor’s leg). Risk to safety: had the driver's seat moved forward without input while the vehicle was in motion, this absolutely could result in loss of control of the vehicle and an accident. Had the sliding side door continued to close on my son's leg, it could have caused severe injury. Had the electrical shock been worse, it could have resulted in burn or injury. The vehicle is available for inspection. It has not yet been inspected by the manufacturer, police, or insurance. The issues have not repeated at this point, although the vehicle was not used the last 12 days. I do not have confidence in its electrical components. There were no warning lamps, messages, or other indications of any problem with the vehicle.

The contact owned a 2018 Chrysler Pacifica. The contact stated that while in reverse(r) and reversing into a parking spot, it was difficult to accelerate over a patch of ice. The contact depressed the accelerator pedal, and the vehicle accelerated quickly and failed to stop while depressing the brake pedal and the vehicle drove through a fence and crashed into a brick building and stopped. The contact stated that prior to the failure, the u-connect phone feature disconnected independently. The failure had never occurred before. The contact stated that the u-connect failure might have been linked to the unintended acceleration failure. No injuries were sustained. A police report was not filed. The fence and a side of the brick building were damaged during the crash. The vehicle was initially towed to the residence before being towed to a collision center, where the vehicle was deemed a total loss by the insurance provider. The vehicle was destroyed. The manufacturer was not notified of the failure. The failure mileage was approximately 159,000.

Vehicle went into limp mode twice. 1st time on 10/28/24, technician found fault for hybrid battery pack, Chrysler technical service bulletin said to clear fault then drive, if fault did not come back release the vehicle work order stated, bring vehicle back if it happens again and replace hybrid battery. 2nd time, 2/06/2026 vehicle went into limp mode again while driving. My safety and the safety of others was put at risk as I was driving on a highway at 65 mph and suddenly without warning and no braking involved went down to 20 mph. A very unsafe maneuver as the following vehicles had no indication I was braking or slowing down. The dealer has confirmed the limp mode incident but so far has been unable reproduce it. The vehicle and components have only been inspected by the dealer. The warning lamps and messages only came on as the event unfolded. A sudden and uncontrollable loss of power. The dealer states that they believe the hybrid battery pack is failing, but Chrysler, stellantis will not replace the hybrid battery pack unless the dealer can reproduce the incident. Extremely dangerous thing to try and recreate.

As prior reported I am the owner of a 2024 Chrysler Pacifica that has a known safety defect in the rear sliding doors that is impossible to disable. This issue also cases parasitic draw strain on the battery that can completely disable the vehicle. The affected system can not be isolated and triggers even without the vehicle in use even effecting the way that the engine runs when in use due to voltage issues that the door issue causes with the battery system in the vehicle. This is not an isolated issue enterprise rent a car in rome, new york also stated to me that they had the same issue with a Pacifica that they use for rentals when I mentioned why mine was in the show this was on 2/2/2026 at 4:00pm. Something should be done to fix this issue or at the very least they should have a way to completely turn off the effected system. Nye Dodge in oneida, new york is doing the repair on my vehicle and can be reached at 315-277-8955 for more information about the cause, and the fix for this issue. I want to reiterate that this is not a one off issue it is a known issue with the Chrysler Pacifica series that should be investigated.

The electric coolant heater (ech) failed (error code p0e15), which is a critical component of the high voltage battery thermal management system. This failure disabled the vehicle's hybrid propulsion system and prevented the vehicle from operating in electric mode. This is a documented systemic issue (ref: TSB s2208000203) that affects the driveability and safety of the vehicle's hybrid powertrain.

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 inspection upon request. The warning indicator appeared immediately upon operation of the vehicle following purchase. No collision occurred, but vehicle occupants, including children, were placed at risk due to the missing safety component.

Rear sliding doors have an electrical issue that can cause a warning that the door is open to be displayed on the drivers information screen while the vehicle is in gear, and being driven. After a moment you will hear a relay click, the error message goes away, and after a while the error message shows up again this repeats in cycles. Attempts to disable the sliding door system for safety removing fuses do not work the system will continue to indicate that the door is open even when it has been closed manually. I just had the vehicle serviced at nye Dodge in oneida, new york so they have better information on what caused the issue, and the fix they can be reached at (315) 277-8955 for information on the issue. The issue I would like to bring to light is that in the event of a defect it is impossible to fully disable the sliding door, and it's sensors I have attempted to pull fuses to shut the system down, and can't find anyway to totally isolate the effected door for safety. I have been reassured the door will not open however I will not be using this vehicle to transport my children until this issue is corrected. You should be able to turn the system off in the event of a failure with one of the sliding doors.

This has been ever since I got my van. Sometime when I drive my lights come on and it goes into limp mode. Most of the time. When I start my van my lights will turn on. I have to turn my car off . Then start again to get my van riding correctly. The other day I was making a u-turn and my engine stalled and I was almost hit by a truck.

The vehicle experienced a failure of the hybrid battery thermal management system. A diagnostic trouble code (p0e15 – hybrid/ev battery pack coolant heater “a” control performance) was set and the check engine light illuminated. This component is responsible for regulating high-voltage battery temperature and is part of the hybrid cooling/heating system required for safe operation and emissions readiness. The failure occurred at approximately 100,700 miles on a 2022 Chrysler Pacifica hybrid. The battery coolant heater is a sealed, high-voltage electronic component with no maintenance or wear interval and is not a consumable part. Loss of proper battery temperature control can affect hybrid system operation, charging, regenerative braking, and power availability, and can potentially result in reduced power or limp-mode operation as the vehicle attempts to protect the high-voltage battery and inverter. The problem was confirmed by a Chrysler dealership and an area service manager using factory diagnostic equipment. The fault code is stored and permanent. The vehicle was inspected by the dealer, and the component was diagnosed as failed and requiring replacement. No accident, misuse, or maintenance neglect was involved. The manufacturer declined warranty or goodwill coverage based on internal policy, despite the failure occurring immediately beyond the hybrid warranty mileage threshold and involving a non-wear, safety-critical hybrid thermal management component. The repair estimate is approximately $1,900 out of pocket. The warning indicator (check engine light) first appeared at the time of failure. The component remains available for inspection and replacement by the dealer. Also the dealership did not provide is with a written justification for the denial and corporate (stellantis) stated that they were not able to provide justification either other than what the automated prompt was giving them (that the part was not covered under goodwill).

Van is only 2 years old, maybe 30k miles on it, and it dies while in motion from "electrical issues" of some sort, that are not even battery related. Never seen this in a vehicle ever. Happened to my wife twice in one week while transporting children. They are very lucky to be alive still. This model should not be allowed on the market in this condition.

Went to start vehicle and it was possessed. Would not turn over. Wipers lights everything was going off. Could not get it out of a/c mode. When hooked to a computer at mechanics it can only read two modules. Ecm is malfunctioning.

I am reporting a safety defect involving my 2021 Chrysler Pacifica hybrid. The vehicle experiences repeated hybrid system failures, including “system charging” errors, rapid battery depletion from full to zero within minutes, and vehicle stalling. These failures have occurred multiple times, even after dealership repair attempts. The vehicle has stalled and been towed more than once, most recently on September 26, 2025. Now, today, January 20, 2026, the vehicle has once again stalled and will have to be towed for the third time since purchasing in August 2024. This has left us stranded once again. This is a serious safety concern, especially given the risk of stalling while driving. I transport elderly family members and depend on this vehicle for medical appointments. I am requesting NHTSA document this issue and review whether this represents a broader safety defect.

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 and would not shift into gear upon starting the car. We continued to have issues in fall 2024/winter 2025. It did great throughout spring and summer, began issues again in fall 2025 into this winter 2026. It has left us stranded, unable to get the car to shift sometimes for 10-15 minutes while we "warm up the car" but sometimes it takes 30-60 minutes. We've began putting a space heater nearby it for a couple of hours each morning before we need to drive it, but that doesn't always work either. While extremely frustrating, it hasn't been considered dangerous until a week ago. We came out of church and it was chilly, so I expected it would not shift into gear. It surprised me when it started and shifted. However, as soon as I got on the main road up to 40mph, the engine completely lost power and threw all the same alarms. The stretch of county road had no shoulders and deep ditches, so barely made it coasting to a neighborhood to pull over. Searching on the internet, we narrowed it down to the can bus star connector, replaced it, and it drove better than ever! until it was cold that night! likely needs soldered, can't reach it behind glovebox.

Red turtle symbol, vehicle going to shut down, indicates issue sensing power from the hybrid drivetrain.

The contact owns a 2020 Chrysler Pacifica. While the contact's wife was driving at an undisclosed speed, the engine seized in the middle of the road. The contact stated that there was no power to the vehicle. The contact stated that the failure occurred close to the residence, and there was not a lot of traffic. The driver was able to exit the vehicle and get to a safe area. The contact's brother-in-law was contacted for assistance; however, the driver became impatient waiting for assistance. The driver attempted to restart the vehicle, and the vehicle started. The help arrived, disconnected and reconnected the battery cables, and the vehicle was driven to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer; however, the dealer was made aware of the failure. The contact was informed that a recall was issued, but for hybrid vehicles. In addition, the contact referenced an open investigation for the failure. The contact stated that the failure had occurred twice within two weeks. Additionally, the warning light that the “auto start/stop unavailable” had remained illuminated since August 2025. The manufacturer was not made aware of the failure. The failure mileage was approximately 52,000. The VIN was unavailable.

On October 31, 2020 (before our purchase of the van) the previous owner had to take the van to Chrysler for hesitation in the transmission shifting. On June 14, 2021 (only two weeks after purchase), we had to drop it off for intermittent shifting issues with what seemed like skipped gears. No engine light came on, and the van was returned stating an inability to reproduce the issue. On February 7, 2022 we brought the van to Chrysler after taking it in a few times to carmax to resolve the the disabled "start/ stop" system. The light would intermittently come on indicating the system was unavailable, and shifting would be erratic. An inspection and recall work for the pcm was performed. In June of 2023, the uconnect system stopped working intermittently. The gears were still shifting roughly with the shift knob becoming increasingly more difficult to turn. An independent shop found no solution with an unknown timeframe on the delivery of a new transmission. In June of 2023 while driving, the van shut off completely while in motion. After a few minutes, it started up again and drove as if nothing was wrong. June 24, 2023, we took the van to Chrysler with the same issues. At the time there was still a back order of transmissions for the van. Upon contacting Chrysler, we found out that there was a recall effective on the new transmission and the company rush ordered the part to the shop. As well, the uconnect system was also addressed. The issue was fixed. After a few years of reliable service, the van functioned normally with rough shifting and start/stop system failures still an issue. In January of 2024, the van would not start at first try. Often my wife was able to get it started after sitting for awhile. In other cases, changing the key fob helped. Changing the aux battery repaired the issue temporarily. Now it won't start at all. The starter was misdiagnosed by an independent shop with Chrysler finding a failed transmission once again.

After a curb impact, the vehicle immediately experienced a no?start condition. The failure appears to be collision?related electrical damage in wiring routed through the lowered?floor mobility?conversion area installed by braunability. The vehicle was fully operational before the impact and became completely inoperable immediately afterward, with no warning lights or prior symptoms, creating a safety risk for mobility access. United access (braunability dealer) performed no diagnostic scan, no wiring inspection, and produced no documentation. They stated they could not identify the cause or access the wiring. Houston Dodge Chrysler Jeep ram produced no diagnostic findings. Their only record, a multi?point inspection, showed no codes, no scan results, and no wiring notes, and incorrectly marked the visibly damaged left front tire as “ok. ” the technician who completed the mpi left shortly afterward, and no further diagnostic work was done. The general manager, ben nash, confirmed in writing that no repairs were performed and the diagnostic fee was waived. United access reported that the dealership told them there were “two shorts in the wiring harness,” but this was only a verbal statement with no documentation, scan report, or technician notes, and no facility has been able to confirm it. An independent repair facility replaced the battery, but the vehicle still would not start. They reported that the wiring is extensive and non?standard due to the braunability conversion and reached a wiring?complexity impasse. Braunability stated they conducted a “thorough review,” but provided no diagnostic evidence and relied entirely on undocumented verbal statements. The precise failure point cannot be confirmed because no facility could access or trace the conversion?zone wiring, but the sequence of events clearly indicates collision?related electrical damage. The vehicle remains in a no?start condition.

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.

Vehicle went into limp mode three times while driving on the highway, forcing us to pull over to the shoulder. Luckily there was a safe place to pull over but created a major safety concern. It triggered code p0a43-00. The dealer initially couldn't recreate the code on 12/18/25 at which point they cleared the code and returned the car to us. It happened again on 12/30/25 at which point the dealer followed Chrysler instructions to conduct pin drag test but no problem was found. Dealer drove 60 mile test and didn't recreate the fault and returned car to us. The same issue again occurred on 1/9/26 at which point Chrysler authorized invasive transmission repairs. This issue directly aligns with recall 23v-010 and NHTSA odi investigation rq24004.

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.

While driving 75mph, the vehicle shut down with a message to pull over. All acceleration was lost. We had to navigate, without warning, across 3 lanes of traffic to pull over on the right side of the highway. This was extremely unsafe as we were slowing down and essentially cutting off other vehicles who were honking at us as this was a traffic hazard. All 6 members of my family were in the vehicle. We had this happen another 3 times before arriving home. I took it to my local dealer, who could not replicate it. They performed a software update, which I have since learned would never fix this problem. We had it happen to us 5 more times, so I took it to another dealership, who initially could not replicate it. In all cases, we had the following check engine light codes be triggered. I have screen shots of them from my personal obdii reader: p0a43 "drive motor 'a' position sensor circuit intermittent", c2225 "status: mil - pcm disabled edu: no sub type information". After doing my own reading, it seemed many others have experienced the exact same symptoms and it has required a transmission repair/replace. I also learned most people had a battery charge on the high voltage battery (as this is a plug-in hybrid) when the vehicle shuts down. I charged my van, took it for a ride at 75mph and it occurred within the first mile. I took it back to the dealership, and at this point, I refuse to drive it until the hardware fix happens. It seems like this should be a recall for all vehicles that can have this problem. It is extremely unsafe as it occurs at 70mph+ speeds.

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.

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.

This submission supplements my prior NHTSA odi complaint regarding the same vehicle and loss-of-motive-power condition. On Nov 8, 2025, the vehicle experienced a loss of propulsion at highway speed, creating an immediate safety risk. The vehicle could not maintain speed and required evasive action with no propulsion to avoid traffic hazards. Following the incident, the vehicle was inspected and stored diagnostic trouble codes p0a3f-00 and p0a43-00 were retrieved, relating to drive motor position sensor / resolver signal loss or degradation. These fault codes are associated with loss of propulsion and indicate a propulsion control signal-path fault, rather than a condition resolved by software calibration alone. The vehicle remains available for inspection and is out of service at a dealership due to unresolved safety concerns. Since my prior odi complaint, I provided formal written notice to the manufacturer describing the incident, the retrieved fault codes, and the safety implications, and requested a written response. Receipt was confirmed by usps certified mail on January 6, 2026. No written response was provided, and repeated attempts to contact the manufacturer through customer service channels were not returned. The manufacturer authorized only a recall firmware update and declined to authorize or perform the intermittent wiring and resolver diagnostics identified in its diagnostic procedures for these fault codes. The firmware update does not inspect, repair, or replace the resolver, wiring, or related hardware indicated by the stored codes, and does not determine whether the underlying propulsion fault has been corrected. As a result, the vehicle has been out of service for more than two months, and the risk of another loss-of-propulsion event remains unresolved. This update documents the manufacturer’s non-response after notice and reliance on a software-only remedy that does not address the indicated propulsion system fault.
