2021 Chrysler Pacifica: check engine light

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

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.

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).

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.

Incident: While driving at highway speeds (65–75 mph), the vehicle issues imminent-shutdown warnings, the reduced-power (‘turtle’) light and check engine light illuminate, and the vehicle loses motive power. The driver must pull over to the freeway shoulder immediately and restart the vehicle. The condition is intermittent, occurs after cold starts, and sometimes with cruise control engaged. Safety Risk: Sudden loss of motive power at 65–75 mph without warning creates extreme crash risk. This is the exact risk stated in the recall notice. The software-only remedy appears insufficient. FCA’s own Warranty Extension Campaign XE1 — covering transmission replacement at unlimited years/unlimited mileage — suggests FCA is aware the software fix may not be adequate. Requested Action: Please investigate whether the recall remedy is adequate or whether physical transmission replacement is required. This vehicle has been documented experiencing the recalled defect seven times after the recall repair was completed.

On January 14, 2026 while driving on highway fast lane warning light came on that engine was going to shut off and withing a few minutes it did. I managed to pull over off the freeway before engine completely shut off. Turned everything off and waited about five minutes and turned car back on. Car ran with engine warning lights on. Took it to Carl Burger Dodge but they could not check in the car due to an abundance of work. Asked that I make an appointment later. On January 26, 2026 while driving on the 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 the federal safety agency had previously identified as a problem.

On [XXX] while driving my vehicle on the fast lane of the freeway the warning came on that the vehicle was going to shut down soon. I was able to pull over to the slow lane and immediately exit the freeway and as I was exiting the freeway the vehicle completely shut down. I was able to move the car to park in a safe area on the street with what little power it had. Shut the vehicle down and contemplated what to do. I waited for a few minutes and then turned the engine on and it drove but the orange 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)

While driving down the highway at 70 miles per hour ater driving 2.5 hours our 2021 Pacifica hybrid minivan flashed a warning on the vehicles display saying approximately "Warning Engine Shutting Down". The engine immediately shut down in the middle of the highway and we were forced to coast off the highway to the shoulder. The engine warning light came on. We turned the car off for a few minutes and proceeded to start the engine. The engine warning light was still on, but the other message was gone. We attempted 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.
