2021 Chrysler Pacifica engine problems

Filed Nov 5, 2026 · Electrical, Engine · SC

We drive an 2021 Pasifica hybrid crysler van. We got a recall card for the hybrid battery. We took it into the dealership they installed the software, said it passed, then a month later engine light came on. We took it back to the dealership they scanned it and done a soak test and everything else to go with it and the code was POBBE and battery has failed. They opened a star case because Stellantis / Chrysler said our milage was to high at 159000 for the recall to cover it. Star case manger called us to let us 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!!!

We took our van in for the 52d recall of the battery being defective and can catch on fire!! for our 2021 crysler pasifica hybrid van for them to update the software for the hybrid battery and to monitor it. Not even a month later we had to take it back to the dealership mechanic because the check engine light came on. They said the hybrid battery is bad and its under the recall 52d. We reached out to Stellantis and went back and forth because they didnt want to honor it. In the mean time we have been out of a 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

We received a recall paper in the mail to stop driving our vehicle, and take it to the nearest Chrysler dealership to have our 2021 hybrid pacifica van hybrid battery for a software update and monitor of the hybrid battery replacement for a recall 52D. Because the hybrid battery will catch fire. We took it in, they updated the software and said it passed. We drove it not even a month and the check engine light came on. We took it back and they said our hybrid battery needs replaced, a code POBBE that ties to recall 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

I am writing about a mechanical failure on my 2021 Chrysler Pacifica Hybrid. Recently, I took my vehicle in for 2 recalls associated with this model. Recall #: 66B, pertaining to the rearview camera & 52D, which corresponds to the high voltage battery. Recall #: 52D could not be completed at the certified Chrysler dealership due to the failure of the Electric Coolant Heater, throwing diagnostic trouble code, (P0E15-00). Due to my vehicle being past its warranty period, at the time of service, by 9,190 miles, I 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 federal safety agency 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".

Driving on the interstate at high speed, when check engine light comes on, warning message - Stop Safely Vehicle Will Shut Off - and red turtle warning indicator (limp mode). After a short time, vehicle will no longer accelerate. I pulled over to the shoulder, stopped and shut off engine. Restarted after a few minutes and everything appeared to work fine, with check engine light on. About 15 minutes later, it happened again. The dealership serviced the vehicle. Found error code P0A78 for driver moteo "A" 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.

My 2021 Chrysler Pacifica Hybrid has a recurring hybrid/electrical defect that causes the accelerator to lose all power while driving, leaving the vehicle unable to accelerate or respond to throttle input. The vehicle remains “on,” but it cannot move under its own power and must be coasted or pulled over immediately. This has happened in traffic, including with children in the vehicle. The dealer confirmed fault code P1A21‑00 and documented that the high‑voltage system can lose its loop connection, which results 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.

This is an intermittent issue that has been happening for a while now and the car was sent to the dealership twice but the issue still persists. The engine would shuts down or partially loses torque all of a sudden and the steering becomes very stiff. At the same time you would see all kinds of alarms, error messages, and check lights on the dashboard. I would then have to pull over to the side of the road, turn off the car, then try to start it back up. Usually after several attempts (one time that took nearly 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.

While driving at normal road speed, the vehicle suddenly lost propulsion and entered limp mode. A turtle warning icon appeared along with multiple system fault messages. The vehicle began slowing down on it's own and was unable to accelerate. I pulled to the side of the road. The vehicle displayed an error "Stop Safely Vehicle Will Shut Off Soon". After sitting for a period of time, the vehicle restarted and was able to be driven again, but the failure occurred without warning and created a dangerous situation in 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.
