2021 Chrysler Pacifica fuel system 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

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 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 contact’s daughter owns a 2021 Chrysler Pacifica. The contact stated that while operating the vehicle, there was a strong fuel odor inside the vehicle. The contact’s husband inspected under the hood and became aware that there was a pin-sized hole in the fuel line and that there was fuel leaking inside the engine compartment. The contact stated that the fuel supply line was touching the engine and the vibration from the engine had caused the pinhole in the fuel supply line. The fuel supply line was replaced by the husband, and the vehicle was repaired.

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 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.

I am reporting a critical manufacturer-imposed restriction that prevents the completion of a life-saving safety campaign, Recall 52D (the federal safety agency ID: 24V362), which carries a strict "Park Outside and Do Not Charge" advisory.My vehicle has an active fault code P0E15 (Electric Coolant Heater control performance), which is a well-known, widespread factory defect in Chrysler Pacifica Hybrids. When I took the vehicle to an authorized Stellantis/Chrysler dealership to perform the urgent 52D safety flash, the dealer officially 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 the federal safety agency to investigate FCA US's refusal to deploy safety updates on vehicles with active P0E15 codes.

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.

This 2021 Chrysler Pacifica Hybrid has a severe and recurring history of catastrophic high-voltage hybrid powertrain and transmission failures that cause a sudden loss of motive power while driving, presenting an immediate safety hazard. The vehicle has already required two full automatic transmission (eFlite EVT) replacements under factory warranty due to internal failures. It has experienced multiple high-voltage component repairs, including software modules for the power inverter. The vehicle is currently 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).
