The car's lithium batteries caught fire to the point of smoldering. This happened at the end of the charge cycle. The car was parked in our garage and if the fire department did not come to help, the fire could have intensified and burned down our whole house. We are very thankful we caught it so quickly. No warnings or issues were apparent with the vehicle when it was parked and put on the charger.

We recently took our Hybrid Chrysler Pacifica to the dealer and they mentioned that there are multiple engine and transmission mounts that need to be replaced in addition to the entire transmission. I reported to them over the years that the vehicle stutters up steep hills (>13.5 degrees). The electric motor produces too much torque, lurches forward, then cuts off and repeats the process. In doing so the electric drivetrain motor is twisting the vehicle apart. It is certainly a safety issue. If we get it fixed, it will certainly happen again and to anyone that has a steep driveway or goes up inclines at less than 5 mph. The process is easily repeated. Thank you!

Recall Z11 was announced in early February 2022 due to fire risk which prompted Chrysler to issue a recommendation that owners not charge their plug-in hybrid Pacifica Hybrids and to park them outside until the fix was completed. More than six months have passed without subsequent update to resolve this recall, and not only is no part or remedy identified, the underlying cause has yet to be identified. This is after two previous recalls, U94 in October 2018 and W46 in June 2020, which were also announced by Chrysler due to fire risk for the Pacifica Hybrid. Chrysler's guidance of parking the vehicle outside and not plugging it in to charge is unsatisfactory and illogical. The normal operation of the plug-in hybrid system leads to the gasoline engine and regenerative braking charging the high-voltage battery during its "Hybrid Mode" operation even when the vehicle has not been plugged in to charge the high-voltage battery. Based upon other recent fire risk recalls related to vehicles with high-voltage batteries such as the Chevrolet Bolt EV--which has led to numerous manufacturer repurchases and complete battery replacement for all affected models--Chrysler's response is neither timely nor sufficient. It is past time that definitive resolution be provided to owners of vans that have already been affected by two prior fire risk recalls and now have been waiting six months with recommendation to not use the vehicle as designed, marketed, and advertised at the time of sell. Given the unresolved nature of recall Z11, I request action be taken to require manufacturer buybacks of the affected products at this time.

I have Pacifica Hybrid 2017 model minivan with a lot of problems. More than 6 times the minivan was not starting and if starting it would have all the check engine (so i needed to leave the minivan with 2 small kids and take a car service ) some of the signs that would all of a sudden start are service Hybrid Vehicle system , service electric throttle control park sense unavailable ,Automatic High Beam Disabled ,press break to prevent rolling ,Blind spot alert temporarily unavailable in the middle of the road while I am driving . I towed the car to Chrysler and they won't pay for it as it was a hybrid problem, and it was under warranty. The dealer agreed that it was a hybrid problem under warranty, and they would fix it as it was a problem from the manufacturer. In a week the dealer said it was fixed. After I was taking the van home and while i was on the road all the signs came up on the control panel. It has all sorts of warning on the panel as mentioned above. I realized the car had the same issue. It won't let me change the gears and stopped completely when I came home. Then I called the dealer and complained, and they said to bring it back however they won't help me with the towing service. Again aftre 1-2 days the car started so i took to the dealer they said they have found the problem they don't know so Chrysler tech team is working on it. Then after 2 weeks they said they have fixed the car and also test drove . However i came home and after 3-4 more days the car still had same issues. It stopped on the highway in the. I managed to move to the rightmost lane and stopped over there on highway. This was a very scary incident. I gave the van back to the dealer and Chrysler reps again said they wil look at it . However, after 4 th attempt I gave them and brough it back . The problem still persists. No help from Chrysler or the dealer. each time they take more than 3-4 weeks and leave you on with no rental help as well.

Our Pacifica plug-in hybrid intermittently wouldn't start beginning in October, 2021, each time displaying a "Service Charging System" message and Check Engine light. In one case, it was on and would not shift into Park, and we got stuck ~30 miles from home, with kids, and had to arrange for pick up and transportation. After many attempts, we were able to start it and drove it to a dealership in Plymouth, MI on November 15th. It has been there since; the dealership wanted to replace the high voltage (hybrid) battery under warranty. Chrysler would not authorize this part to be ordered and directed the dealership to replace the Onboard Charging Module. That did not resolve the issue and they eventually (on December 27) ordered a new HV battery (which still has yet to arrive).

THE MOST RECENT OCCURRENCE- OF MANY- WHERE THE VEHICLE NOT OPERATING AS IT WAS SHIFTED TO/ NOT STAYING ON/OR TURNING OFF WHEN THE IGNITION BUTTON IS PRESSED IS AS FOLLOWS. IN A (FLAT) PARKING LOT THE VAN WAS PARKED AND TURNED OFF> THE BRAKE WAS PRESSED> THE IGNITION BUTTON WAS PRESSED TO TURN THE VAN TO 'ON' AND THE WORD 'RUN' WAS ILLUMINATED- IT WAS RUNNING IN FULL ELECTRIC MODE WITH A BATTERY OF ~85% > THE SHIFT KNOB WAS TURNED FROM P TO R> THE VAN WAS REVERSED OUT OF A PARKING SPOT > THE BRAKE WAS PRESSED AND THE SHIFT KNOB WAS SPUN TO D > THE BRAKE WAS RELEASED AS THE STEERING WHEEL WAS TURNED TO PIVOT OUT OF THE PARKING LOT HOWEVER THE CAR CONTINUED IN REVERSE. AT THIS POINT I STARTED FILMING TO 'CATCH' THIS PROBLEM ON FILM SINCE SIMILAR REPORTED ISSUES ARE ALWAYS 'NON DUPLICATE-ABLE' AT THE DEALERSHIP. THE IGNITION BUTTON SHOWED 'RUN', THE "D" ABOVE THE SHIFTING KNOB WAS BLINKING BLUE, THERE WAS AN ORANGE 'CHECK ENGINE' LIGHT TYPE ICON SHOWING ON THE MAIN SCREEN WHERE THE MESSAGE "SHIFT TO P TO START" WAS ALSO SHOWING. I HAD TO PRESS ON THE BRAKE, SHIFT TO P, AND TURN OFF THE CAR, THEN TURN ON THE CAR IN ORDER TO HAVE THE CAR BE ABLE TO DRIVE IN A FORWARD MOTION. WHILE THIS WAS IN A QUIET PARKING LOT ME SITTING IN THE MIDDLE OF A LANE WAS NOT A PROBLEM, AND THANKFULLY I WAS NOT CLOSE TO THE NEXT CAR WHILE I WAS REVERSING SINCE UPON SHIFTING TO 'D' I CONTINUED BACKWARDS TOWARDS A ROW OF CARS. HOWEVER, I LIVE ON A BUSY STREET AND OFTEN HAVE TO REVERSE OUT ONTO A 4 LANE ROAD WHERE IT IS IMPERATIVE THAT THE VAN MOVE FORWARD WHEN SHIFTED AS SUCH TO AVOID BEING HIT BY FAST MOVING TRAFFIC. I HAVE ALSO HAD SIMILAR OCCURRENCES HAPPEN, AND FREQUENTLY HAVE TO PRESS THE IGNITION BUTTON MULTIPLE TIMES TO GET THE VAN TO TURN OFF ONCE PARKED.*DT*JB

3PE25009 · Intermittent Loss Of Electric Power Steering
Opened Sep 5, 2025 · No close date supplied
Status: open (inferred from source dates) · Steering:electric Power Assist System
The Office of Defects Investigation (ODI) is opening this Preliminary Evaluation to assess the scope, frequency, and potential safety consequences of alleged defects related to the electric power steering (EPS) system in model year (MY) 2017–2018 Chrysler Pacifica vehicles. ODI has received 94 Vehicle Owner Questionnaires (VOQs) reporting a condition in which the steering system exhibits a sticking sensation during gradual turns, particularly when the steering wheel is positioned near the 11 o'clock or 1 o'clock position. Complainants allege that during these events, increased steering effort is required to return the wheel to center. In many cases, this is followed by a sudden reactivation of EPS assistance, which may result in an oversteer condition. This behavior could increase the risk of a crash, especially at higher speeds. ODI has identified multiple VOQs describing similar symptoms. This investigation will assess the frequency, root cause, and potential safety-related consequences of the alleged EPS malfunction. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
RQ24004 · Loss Of Motive Power Due To An Internal Wiring Connector Short.
Opened Feb 27, 2024 · No close date supplied
Status: open (inferred from source dates) · Electrical System:wiring
On July 22, 2022, the Office of Defects Investigation (ODI) opened investigation PE22-008 regarding complaints alleging a loss of motive power condition potentially due to a transmission malfunction in Model Years 2019-2021 Chrysler Pacifica Plug-In Hybrid Electric Vehicles (PHEV). On January 17, 2023, Fiat Chrysler Automobiles (FCA) issued safety recall (NHTSA Recall 23V-010) involving 2017-2023 Model Years (MY) Pacifica Plug-In Hybrid Electric Vehicles (PHEV) produced between August 12, 2016, through January 9, 2023. The recall states that the loss of motive power condition in these vehicles is caused by an internal transmission wiring connector that may short circuit, resulting in an unexpected engine shutdown. An unexpected engine shutdown can cause a loss of drive power, increasing the risk of a crash. In discussions with FCA on Recall 23V-010, ODI confirmed the recall was related to investigation PE22-008. The remedy for 23V-010 is to update the Power Inverter module (PIM) and/or Instrument Panel Cluster (IPC) software to provide drivers a message stating “Stop Safely - Vehicle Will Shut Off Soon” followed by a chime and MIL, PRNDL blinking (on cluster and shifter knob), low SOC (State of Charge) warning and reduced power mode. The recall remedy does not replace the defective hardware that was described in Recall 23V-010, and the wiring connector short still exists on these vehicles. To date, ODI has received 132 reports for the population of vehicles subject to recall 23V-010. These reports allege a loss of motive power condition that reduces the vehicles speed, followed by dashboard warning lamps displaying messages associated with recall 23V-010. The presence of these warning lamps and messages indicates the vehicle likely had the recall remedy applied. Follow up discussions with FCA confirm their remedy does not prevent a loss of motive power, but instead limits torque to the engine and after an unspecified number of miles or period of time, the engine will shut down. When this occurs, FCA relies on the owner to transport the vehicle to a dealership after they experience a loss of motive power condition, at which time the defective hardware is replaced. Furthermore, the dashboard messages introduced in the recall remedy may cause the driver to pull over in an unsafe location. Pulling over in an unsafe location may expose the occupants to undue harm. The Office of Defects Investigation is opening this Recall Query (RQ) to assess the adequacy, frequency, and safety consequence of the remedy for recall 23V-010. To review the ODI reports cited in the opening resume ODI report identification number document, go to NHTSA.gov.
RQ24001 · Ignition-off High Voltage Battery Fire (remedy Effectiveness Of Recall 22V-077)
Opened Jan 16, 2024 · No close date supplied
Status: open (inferred from source dates) · Electrical System:propulsion System:traction Battery
On February 11, 2022, Fiat Chrysler Automobiles (FCA) issued a safety recall (NHTSA Recall 22V-077) on all 2017-2018 Pacifica Plug-In Hybrid Electric Vehicles (PHEV) produced between August 12, 2016 through August 7, 2018. The recall addresses ignition “OFF’ fires that originate at the high voltage (HV) battery pack assembly. An ignition ‘OFF’ vehicle fire can result in an increased risk of occupant injury, injury to persons outside the vehicle, and property damage, with little to no warning. At the time of the recall filing the root cause of the vehicle fires was unknown and under investigation by FCA and suppliers. A software remedy designed to improve thermal event detectability by monitoring battery diagnostics is currently being installed on subject vehicles as an interim remedy. As of November 23, 2023, the root cause of the battery failure is unknown. From December 2022 through December 2023, NHTSA has received four consumer complaints (VOQs) alleging vehicle thermal events involving recalled 2017 and 2018 Chrysler Pacifica PHEVs. Additional information collected from complainants confirmed a thermal event originating near or at the HV battery pack after the Recall 22V077 remedy had been applied to the vehicle. Follow up meetings with FCA and suppliers in November and December 2023 to discuss the ongoing root cause investigation and post-recall remedy incidents indicated a recent increase in HV battery thermal events. Furthermore, a review of NHTSA complaint data indicated the post-recall HV battery thermal event complaint rate now exceeds pre-recall levels. The Office of Defects Investigation (ODI) is opening this Recall Query (RQ) to review the effectiveness of the original recall remedy, understand the root cause of the battery fires, investigate additional reports of Pacifica PHEV HV battery fires, and to increase monitoring of the manufacturer root cause investigation. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.
