2021 Chrysler Pacifica fuel/propulsion system 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…”

“The vehicle experiences a complete loss of motive power due to the high voltage battery pack reaching a temperature of 131 degrees F. The defect first surfaced on March 7th, 2022. The vehicle shut down on multiple occasions while driving, and the original owner had the vehicle bought back by FCA US. The vehicle was sold to me in 2023, and it has shut down on numerous occasions for me as well, some of which were while driving. In total, between both owners, there have been 11 failed repair attempts, involving 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 is a 2021 plug-in hybrid minivan within the population of an open safety recall for internal high-voltage battery failure that can result in fire, including while parked and not charging. The recall remedy, performed at a dealer, consisted of a battery control module software update intended to detect the defect, plus battery pack inspection and replacement if flagged. Approximately six weeks after the recall remedy was performed, the malfunction indicator lamp illuminated. Scan of the hybrid battery 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…”

“Our van will not charge when plugged in and a message on the dashboard says "Service Charging System". Also, the car will not go into reverse when turned on and the gear is showing in "R", reverse. It will not let me back up out of our garage.”
