2021 Chrysler Pacifica engine problems

“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…”

“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…”

“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…”

“Vehicle once it came to a full stop on the highway the check engine light popped on and would not go out. it drove okay the reset of the way home until the last few miles, came to a stop sign and vehicle shut off. placed into park and restarted the vehicle and continued journey home”

“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 NHTSA 26V362 manufacturer filing states that the required remedy includes a…”
