2021 Chrysler Pacifica

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.

The Electric Coolant Heater (ECH) failed (Error Code P0E15), which is a critical component of the High Voltage Battery Thermal Management System. This failure disabled the vehicle's hybrid propulsion system and prevented the vehicle from operating in electric mode. This is a documented systemic issue (Ref: TSB S2208000203) that affects the driveability and safety of the vehicle's hybrid powertrain.

I am reporting a safety defect involving my 2021 Chrysler Pacifica Hybrid. The vehicle experiences repeated hybrid system failures, including “system charging” errors, rapid battery depletion from full to zero within minutes, and vehicle stalling. These failures have occurred multiple times, even after dealership repair attempts. The vehicle has stalled and been towed more than once, most recently on September 26, 2025. Now, today, January 20, 2026, the vehicle has once again stalled and will have to be towed for the third time since purchasing in August 2024. This has left us stranded once again. This is a serious safety concern, especially given the risk of stalling while driving. I transport elderly family members and depend on this vehicle for medical appointments. I am requesting NHTSA document this issue and review whether this represents a broader safety defect.

Reversing onto roadway and shifted from reverse to drive via rotary dial and vehicle went into park and would not move causing me to block the roadway. In addition and even more concerning was that the vehicle could not be turned off and any and all actions to do so just left the car "on" and the hybrid system running. Eventually we pulled the battery cable on the main 12v in the trunk and the reset allowed us to move the vehicle again. I sat across a busy section for twenty minutes with no way to move, turn off, or overide the system with three kids with me in a busy traffic area. The vehicle has not reproduced the issue as of yet. The dash had multiple warnings for park system and service various items needed. this occurred 12/17/2025 with 70,000 miles.

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.

The ESS battery fails constantly and manufacturer will not find problem and just replaces battery. When the ESS battery fails it drains the main battery which then leaves the driver and its occupants at risk of being stranded. The transmission is an electronic transmission and if the battery fails while driving that could compromise the occupants also. We have had to have the battery replace twice and a third time tomorrow 9/21 if the dealership will "fit" us in. The ESS system will tell you it is unavailable but only after the battery has failed.

While driving my vehicle soon after purchase I notice an engine light on along with a huge fan noise from under the hood. Addressed the issue with dealer they diagnosed the car and so called fixed the issue. about a month ago I’m driving the car on a residential street and noticed the car jerking loud fan noise and the whole dashboard light up saying service hybrid service engine and transmission.. Suddenly the engine stops in moving traffic. The vehicle windshield wipers cut on by themselves and the car stayed in park.. tow the vehicle to the dealer using only a dolly tow truck due to vehicle unable to be placed in neutral. Dealer calls to give update and noted no codes were stored and there is currently no issue with vehicle..He suggested to keep the vehicle longer to see if the problem returns. I’m afraid the electrical issue that is going on with this hybrid will cost me and my children life one day. this vehicle is not safe to drive and I am stuck in a purchase contract.

Since week 1 of owning my brand new 2021 Chrysler Pacifica Hybrid, I have had issues of loss of motive power. I have done all of the recall remedies yet my car with a 35day old 12v battery not only died on me, but drained every battery in my vehicle so that I couldnt open my doors. The vehicle was unable to be jumped so that it could be driven, so I ended up paying o or $1000 in towing to get the vehicle to my dealership to be diagnosed,AGAIN. That happened on July 12th, I finally had it towed on July 14th to my dealership & it has been there since. Although the PIM & BATTERY are under WARRANTY, Chrysler is refusing to reimburse me any of the tow fees & only 20 days of a rental I have now had for a month. The dealership installed the PIM which cleared a couple of codes, but not all. They installed ANOTHER new 12v battery, which was immediately drained. They have ordered another coolant something or other for the battery & here we are. I attempted in 2022 to retain a lemon law lawyer but he gave up very easily once Chrysler just stopped answering him.he said because I had my car updated under the class action lawsuit Moran is Chrysler FCA et Al, I was not able to continue under Lemon Law. I have not been able to find a lawyer, even one from the Class Action Lawsuit, to assist me in fighting Chrysler to do something to make me whole. My vehicle needs to be inspected in less than 40 days but at this point my 5 yr old vehicle can NOT pass the Pa inspection, so what am I supposed to do? I live in the mountains, have an 8 yrold grandchild that im raising & certainly cant afford to rent cars forever. I still haven't gotten my pension from the Coty of Philadelphia after 3 years of retiring after getting hurt on the job. I just read an article about the Office of Drfective products investigating Chrysler in 2022 for EXACTLY the problems I continue to have!!

When driving our van from Nashville to Memphis, we were 2 hours from home when we received an on screen alert stating “Stop Safely - vehicle will shut off soon”. This was in a construction area with little to no shoulders to pull the vehicle over as power loss began to occur. We contacted Chrysler for help but the nearest dealership told us the earliest they could see the vehicle was 3 weeks from Tuesday. I had 3 children in the car ages [XXX}. A web search for this shows how prevalent this issue is with several blogs and Reddit forums indicating a problem. The NHTSA even has an open investigation into this specific issue. Apparently the only fix is a full transmission replacement, but we have no assurance from Chrysler that will happen and now our van is left 3 hours away in Memphis as we had no choice but to leave there.
