2021 Chrysler Pacifica Electrical problems

know that it falls under the warranty and they ordered a battery should arrive Dec 15 2026 at the earliest. Called the dealership to verify. They said yes its ordered. 2 days later Stellantis called us and said they canceled the order and it will not be covered under the warranty recall because of our van is over the milage for the recall. She told us to take it to another dealership to see what they say. That would be the 3rd time we done that and this is what they keep telling us. Our van is at the dealership off road because its a fire hazard and can not be driven and they will not honor the recall 52d, Id-25-13 for unlimited miles. Were stuck with no recall getting taking care of. The only option we have is to contact our lawyer and he will be handling this moving forward. Hopefully Stellantis and Chrysler will be 100% held accountable for there actions. I really dont understand how some people can sleep at night knowing they put people at such a high risk of dieing from their vehicle catching fire and expecting people to accept that as its ok. Big safety issue!!!

primary vehicle. Stellantis has finally agreed to order a new hybrid battery and cover our vehicle under the recall 52 and have the dealership mechanic install it 100% free. That was Monday. We have tried to reach out to our star case person Mariah, which she had a lady named Monica call us and we were not able to speak to her, she left a voice mail saying only on the message the part has been ordered? We reached out to the dealership mechanic and he has been more than helpful by letting us know the battery was ordered which he had to look it up when we called because Stellantis didnt not reach out to Auto Nation about our van being approved for the battery recall 52d replacement. Mariah told us last week that when we get approved for the battery that we would need to call her for them to get us a rental. We have been calling leaving messages and no response. Its now week 3 without a vehicle and we have children that have to go to school and the adults have to go to work. But have to ask other people to give us a ride and somtimes are not able to find a ride. When clearly the recall paper states that a loaner vehicle will be provided 100% and we will be takin care of. Please help with them honoring this recall all the way through until it is completed. This has become an inconvenience for our family of 8, because of their mistakes. Were asking you to look into this matter to help us and other people that are dealing with the same recall 52d on their pasific

52d but said its not covered under the recall, and we will have to pay out of pocket. We have been back and forth for over 3 to 4 months because Chrysler, Stellantis, & Mopar keeps denying the replacement of the hybrid battery because they say it passed after the check for the recall, our vin does not match for the recall, our van is over the warranty miles. The last call they gave us a new case # which this is our 4th one and told us to go take it back to the dealership and have them run a diagnosis again to see what it says. We did that and the same code comes back. The dealership opened a STAR case and told us to call Chrysler recall division. We did, she gave us a new case number and told us that a case manager will call us. In the mean time the dealership is waiting and has our van because its a fire recall and hoping that all of the above companies that are responsible for this recall make this right. Please help with this serious matter. Thank you

replacement of the high voltage battery pack, the chiller, the inter-loop heat exchanger, the battery cooling pump, and multiple replacements of the high temp 3-way cabin valve. I eventually traced the apparent cause to the high temp 3-way cabin valve routing engine coolant through the inter-loop heat exchanger at all times, causing the high voltage battery pack to overheat. If the vehicle is left sitting with the engine idling, the vehicle will shut down after less than two from cold. I installed a hose to bypass the heat exchanger in order to address the problem. The repair successfully kept the battery coolant temperature from rising, however, the vehicle still overheats and shuts down. I believe that this model of suffers from multiple design defects in the cooling system making it far more likely than other vehicles to experience a complete loss of motive power.

the problem appeared after the recall repair but has refused to fix it. The vehicle is still unrepaired. 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The radio and infotainment system failed: the center screen on the instrument panel, its operating software, and the audio system. The screen stays blank or unresponsive, and the software crashes or restarts repeatedly. The failure started right after the Recall 52D software update. The vehicle hasn't been repaired and can be inspected at any time on request. 2. How was your safety or the safety of others put at risk? Because the screen doesn't work, I've lost functions I rely on while driving: Radio and audio, including emergency and traffic broadcasts; The screen also crashes and restarts while I'm driving, which is distracting. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Dealer saw the problem and confirmed it appeared after the Recall 52D repair. The dealer has refused to repair it. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The dealer inspected it after the service recall. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

controller returned two stored codes: P1D43 (internal control module shut-off test monitoring time error) and U029A (lost communication with hybrid battery pack sensor module). U029A indicates the battery controller cannot communicate with the module that monitors individual cell voltages and temperatures. The engine and transmission controllers returned no codes. There were no drivability symptoms at any point. The pack charged fully and delivered normal electric range before and after the codes appeared. The dealer diagnosed the condition and the manufacturer approved a high-voltage battery pack replacement. Approximately 24 hours later the manufacturer rescinded that approval and instructed the dealer to clear the codes and return the vehicle to service to see whether the codes reappear. The dealer stated it had not seen an approved claim reversed in this manner. The dealer reports being unable to reproduce the codes after clearing; the duration and conditions of that retest have not been provided. I have requested the engineering findings and the basis for the reversal in writing and was told they are proprietary. The manufacturer has not provided the retest parameters. My concern is that the vehicle is being returned to service with a documented fault in the high-voltage battery monitoring system, on a platform subject to an open fire-risk recall, without the basis for that decision being disclosed.

software update. They stated that this was the reason they intentionally did not perform Recall 66B during my initial service visit. I asked the dealership to confirm with Stellantis or management who would be responsible if the radio became unusable while performing the safety recall. The dealership later told me that they had spoken with their manager and confirmed that if the recall caused the radio to lock up, replacement would be my financial responsibility because the vehicle is out of warranty. I am NOT declining Recall 66B. I want the safety recall completed. However, I do not believe I should be required to assume the financial risk of the radio becoming unusable as a result of the recall procedure itself. I am asking NHTSA to review this situation and the dealership's handling of Safety Recall 66B.

refused to perform the recall. They stated that the manufacturer's diagnostic software (wiTECH) completely blocks the 52D software update from being uploaded if the P0E15 fault is present.I contacted FCA US Customer Care (Case Number: 97720299), and they officially replied that they will not issue a corporate override for their diagnostic software. They are conditioning the execution of a critical fire-safety recall on me privately paying for the repair of a separate known manufacturer defect (P0E15 heater), due to the vehicle's export status.This is a severe threat to public safety and an unacceptable corporate practice. A manufacturer should not be allowed to design diagnostic tools that block critical, life-saving safety recalls due to other unrelated factory defects, effectively forcing owners to drive potential fire hazards unless they pay for commercial repairs. I request NHTSA to investigate FCA US's refusal to deploy safety updates on vehicles with active P0E15 codes.

experiencing a recurring failure and is displaying active diagnostic trouble code P0A78 (Drive Motor "A" Inverter Performance), indicating a critical fault in the high-voltage hybrid propulsion system. Prior to the current failure, the check engine light illuminated, and the vehicle experienced propulsion system degradation. This failure mode risks a sudden shutdown of the hybrid drive system at highway speeds, creating a severe risk of rear-end collisions or being stranded in active traffic. The recurring nature of these transmission and inverter failures indicates a systemic safety defect in the hybrid propulsion system. The issue and the active P0A78 code have been pulled, reproduced, and confirmed by an authorized dealership (Diehl Automotive of Robinson), where the vehicle is currently held and available for inspection. The manufacturer has been notified via an open corporate case (#97399722).

available, even though the remedy stated that it would be available 2 - 3 days. The manufacturer was made aware of the issue and redirected the contact to locate other dealers who might already have the high-voltage battery for repair in stock. The contact had not experienced a failure.

immediate risk of a sudden loss of motive power. Additionally, because these faults are rooted in the high-voltage battery system - a system actively under federal scrutiny and manufacturer recalls for thermal runaway - the failure presents a severe risk of spontaneous vehicle fire, endangering occupants, bystanders, and nearby structures. Yes. The failure was initially recorded by an independent diagnostic scan tool, which pulled several confirmed high-voltage fault codes. The vehicle was then taken to a certified manufacturer dealership, where it has been held in the service department for a month. The dealership has confirmed the presence of a severe system failure and initiated repairs costing at least $1800 (with final costs still potentially increasing). Yes. The vehicle is currently in the possession of, and being inspected by, technicians at a certified manufacturer dealership. Yes, the vehicle's onboard diagnostic system detected severe faults and registered the following confirmed trouble codes: * P0B37 - High Voltage Service Disconnect Open * P0C77 - Hybrid/EV Battery System Precharge Time Too Short * P1AE2 - Battery Energy Control Module High Voltage System Interlock Circuit * P0A0A - High Voltage System Interlock Circuit

in a no-propulsion condition. They also found the HVIL high-voltage connector loose and damaged. The vehicle was in the shop for 18 days for this issue. I picked it up on June 18, 2026, and within 24 hours the same loss-of-propulsion failure happened again. The vehicle is now back at the dealer. The dealer performed recall 52D and updated the BPCM software, but the failure still occurred immediately after pickup. This defect has been reproduced and confirmed by the dealership multiple times and remains unresolved. This is a serious safety hazard because the vehicle loses propulsion without warning and cannot accelerate in traffic.

30 minutes), the car works properly again with no error messages but sometimes I'd still have some persistent check lights on the dashboard. Error messages and check lights that I see include the following: -Service Electronic Stability Control -Autopark Engaged -Shifter Autocorrect Active -Park Brake Temporarily Unavailable -AWD System Temporarily Unavailable -Automatic Emergency Braking off check light -Forward Collision Warning off check light -Check Engine light The dealership has been unable to properly diagnose and fix this issue so far. On the first visit, they replaced the main battery, auxiliary battery, some wire harnesses that I was told had some corrosion, and the adaptive cruise control module. On the second visit, they replaced the CAN Bus star connector. The same issue still persists after replacing all above components.

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.

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.

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.

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.
