2021 Chrysler Pacifica Engine 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

had to pay $1356.70 for the Electric Coolant Heater to be replaced, before my No-charge Recall #52D could be completed. While my vehicle is technically past its warranty period by 10,387 miles], I am reaching out because this specific component, the Electric Coolant Heater, is a well-documented failure point across the Pacifica Hybrid community. The breakdown of this heater directly impacts the vehicle's cabin climate control and the proper thermal management of the hybrid battery system, creating a significant inconvenience and safety concern during cold weather. Section 6 of the NHTSA 26V362 manufacturer filing states that the required remedy includes a software flash to track the battery pack's thermal performance. Because the high-voltage coolant heater core regulates that thermal loop, it is functionally impossible to safely execute the software parameter updates while the module is malfunctioning or failing the dealership's "soak test".

later. The contact stated that the failure was a persistent failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The failure mileage was approximately 50,000.

inverter performance. Used Stellantis Technical Service Bulletin 08-253-24 to diagnose (both modules were out of date) and complete the indicated updates. This is a known issue that has affected many vehicles (per internet forums and that Stellantis has created a TSB. It is an extremely dangerous situation causing the vehicle to enter "limp mode" and requiring the driver to stop in a matter of minutes. Stellantis should recall all potentially affected vehicles to update the modules proactively.

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.

traffic. Diagnostic trouble codes were present related to the hybrid system and high-voltage battery, including P1D43, P1A21, U029A, and U0412. These codes indicate faults in the hybrid control system and battery communication. A Chrysler service department inspected the vehicle, confirmed the trouble codes, and returned it to me without repair because the issue was not immediately reproducible at the dealership. The vehicle has a history of similar intermittent issues, including prior loss-of-power events and repeated service visits for hybrid system faults. The condition is not consistently reproducible, but when it occurs it results in a sudden loss of motive power while driving. This creates a significant safety risk due to unexpected loss of propulsion in active traffic.

highway same thing happened, warning light came on that engine was going to shut off, pulled over from fast lane to side of busy highway and stopped. Turned everything off and waited for about five minutes and started car again with car warning lights on. Drove it that day. Later in the day parked car at a shopping mall and turned car off. When I returned to turn car on warning light came on that engine was shut down. Turned everything off and waited for about five minutes and turned car back on, it drove with engine warning lights on. On January 29, 2026 took car to Carl Burger Dodge and left it there for evaluation and repairs. Question, has there been any recalls or fixes relating to alleged problem an internal transmission wiring connector that may short and can cause the car to shut off? An issue NHTSA had previously identified as a problem.

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.

engine light was still on. I slowly drove it to the Carl Burger Dodge dealership in La Mesa, CA using side streets, avoiding the freeway, approximately 10 miles distance. They would not take my car in for service due to their back log and asked for I to make an appointment which would likely be around two to three weeks away or take it to another dealer that may look at my car sooner. Hesitant, I slowly drove my car to my residence again using only side streets, a distance of about 20 miles. Made it safely but the orange engine light was still on. I have had recall repairs on this vehicle previously. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

several blogs and Reddit forums indicating a problem. The NHTSA even has an open investigation into this specific issue. Apparently the only fix is a full transmission replacement, but we have no assurance from Chrysler that will happen and now our van is left 3 hours away in Memphis as we had no choice but to leave there.

motor "A" position sensor"). The vehicle was towed to the dealer ( 4 hours from home) and after a few days they said the vehicle was fixed and I pushed for them to test drive it on the interstate. Was returned with this comment: " FOUND CODES FOR DRIVE MOTOR "A" POSITION SENSOR CIRCUIT INTERMITTENT AND HYBRID BATTERY PACK STATE OF CHARGE LOW. CHECKED TRANS PLUG AND WIRING VERIFIED OPERATING CORRECTLY. FOUND THAT RESOLVER NEEDS TO HAVE RELEARN PREFORMED. PREFORMED RELEARN ON RESOLVER AND CHARGED HYBRID BATTERY. TEST DROVE VEHICLE ON INTERSTATE AND VERIFIED THAT ISSUE DID NOT RETURN. VEHICLE OPERATING AS DESIGNED." I received a notice of an unlimited mile/year warranty on the transmission for this car, and from what I read on the internet, this is a recurrent issue with a known cause. We were able to get off the road safely in this case, but it is nerve-wracking to drive, especially with my family, in the current state.
