2018 Chrysler Pacifica Electrical System Problems

While traveling 350 miles from my home with my family of five, the vehicle experienced a sudden 'Loss of Motive Power' event. The dashboard displayed the message: 'Stop Safely - Vehicle Will Shut Off Soon.' I lost the ability to accelerate and had to navigate to the shoulder in high-speed traffic. The vehicle is currently inoperable and the 12V battery has since died because the Power Inverter Module (PIM) has stopped maintaining system voltage. This vehicle had Recall 03A (NHTSA 23V-010) performed on July 7, 2023, and the more recent Recall Y40 update performed on March 11, 2026. Despite having the 'latest software remedy' installed less than 30 days ago, the vehicle suffered the exact safety failure the recalls were meant to address. This proves that the software-only remedy is insufficient to prevent the hardware failure (internal transmission wiring short). A formal Vehicle Scan Report performed at Lake Norman Chrysler (Dealer 60945) on 3/30/26 explicitly shows 'Distance Travelled with Light ON: 146 miles' (Page 14), documenting a sustained failure of the motive power system. Furthermore, the dealer’s own certified technician (J. Olmstead) provided a written Action Plan (Page 9) recommending a full Transmission and Power Inverter Module (PIM) replacement. Despite the documented 146-mile failure history and the technician's recommendation for hardware replacement under the XE1 Warranty Extension, the dealership service management is refusing to perform the repair, claiming they cannot 'replicate' the code as an active fault. I am currently stranded out-of-state with an unsafe vehicle that Chrysler is refusing to repair under the established safety warranty.

As I was entering [XXX] between [XXX] and [XXX] the check engine light came on and a warning about finding a service charging station. The accelerator then stopped working, the car stalled out and I was unable to drive the vehicle. Thankfully, I was able to navigate the car to the breakdown lane as it decelerated. I then had to get a tow to the dealership. The engine light came on several times over the last few months prior to this incident but the dealership at shoreline Chrysler jeep dodge were not able to fit in the car to diagnose the issue. Their negligence led to this dangerous situation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Battery drains between starts and has to be jumped in order to start. Takes several attempts before vehicle will start when jumping after battery dies. Often have to reset dash display or media hub as screens go blank after jumping. Has fairly new batteries. Certified mechanics confirmed parasitic drain. Possbly connected to media hub system.

After safety recall 73B was performed on my 2018 Chrysler Pacifica Hybrid on 11/24/25, the vehicle's check engine light illuminated. Code U0412 is identified as a 'stored' code upon pulling OBD information. This is described as "Invalid Data Received From Battery Energy Control Module 'A'" indicating failure of the high voltage battery pack and its control system. The HV battery is available for inspection upon request. My safety and the safety of others are at risk because the recall was issued to prevent a battery fire. The symptoms my vehicle is exhibiting are precisely the kinds of faults the recall's software update is supposed to detect. The check engine light, appeared within days of the recall service. This strongly indicates the recall procedure, specifically the mandatory battery integrity test, was not completed correctly, and/or that there is a failure in the underlying recall procedure itself. This is a widespread issue, with numerous owners reporting the same post-recall failures to their dealership, online, and to Chrysler Cares customer service without satisfactory resolution.

At a stoplight the FCW ( forward, collision), warning dash light went on and engaged the brakes, thankfully, no movement was taking place.I had to put the car in park and then drive to be able to resume.This indicates that it could have occurred at high speeds, potentially causing a collision

Vehicle lost all internal communications while driving. During this incident propulsion was lost, turn signals, hazards, power brakes, power steering, all electronics except speedometer failed. I was unable to put indicators on during this incident outting others at risk. It appears hazards and turn signals are CAN communication which is absolutely insane and a severe design flaw.

Vehicle will start but the shifter will work. It threw a check engine light and check hybrid system code. You cannot get the vehicle out of gear and the shifter will not light up. After shutting the vehicle off and on 3 times it erased and acted like it never happened. This is the third time it has happened. What’s bad you can drive somewhere and be stuck there for hours not knowing if you need a tow or it’s going to reset again. Don’t know if something my happen while driving as well.

My van completely shut off, and all lights on the gear shifter stopped working. Yes, it is available for inspection until the gear shifter is replaced, as recommended by the dealership. The van lost power just as I lifted my foot off the brake to proceed into an intersection. This sudden shutdown created a traffic backup behind me and could have put me and others in danger had I entered the intersection. The issue has only occurred once for my husband while driving but has not been officially reproduced or confirmed by a dealer or service center. Yes. I took the van to the dealer, who suggested replacing the battery and the shifter. I replaced the battery and ordered the shifter, but the second failure occurred after the new battery was installed. In addition, I’ve noticed a continuous clicking sound coming from the van after it is turned off, which does not stop for approximately 5 minutes. There were no warning lights or messages before the failure. After the van shut down, the “start assist” light came on, and it did not turn off until about four days after the battery replacement.

Electrical adaptive, cruise control, forward collision warning, and shifter all malfunctioned. It is available for inspection. There was failure to accelerate at an intersection which almost caused vehicle to be rear ended. The error codes have been pulled and shown by O’Reillys auto parts. The vehicle is pending inspection by an independent mechanic. The adaptive cruise control the Ford collision, warning and service shifter warning lamps all appeared shortly before this problem occurred.

Check engine light came on the day after the automatic start/stop light came on. Engine code read cylinder 4 misfire. We switched all the spark plugs and changed the cylinder 4. A couple days later check engine light came back on brought the vechile into Bergstrum. They put in a name brand cylinder 4 plug and spark plug, 2 weeks later the light came back on, same exact issue. They are now claiming it’s an engine issue potentially. Sounds like this is a BIG problem for 2018 Chrysler pacificas.

Quirk Chrysler Dodge Jeep RAM Of Dorchester refused to perform Recall 73B/24V-536 on my restricted-title Pacifica (reconstructed), citing Chrysler policy. That policy doesn’t exist in the recall bulletin. I need the BPCM software update and any necessary battery replacement under the recall.

The hybrid battery system is malfunctioning. I am not at risk. I am repeatedly getting U0412 error code, indicating a problem with voltage in the hybrid battery system. It only happens intermittedly. I have taken it into the dealer when the check engine light is not on (unfortunately), and they did not find any issue. One time while driving at highway speed, I did get an immediate red message saying "check hybrid system". It went away with the check engine light remaining on for about an hour. This has occurred after (and I think because of) the 73B recall.

On Thursday, July 3, we were on our way out of town and had just gotten on a highway when I smelled something burning, saw smoke (we thought was steam at the time) coming from the hood and heard the engine making a grinding, or rattling noise so we pulled over immediately. My husband got out of the car to start to take a look when another vehicle who had just passed us backed up and motioned frantically saying “Your car is on fire!” So we got out and looked under the front of the car and sure enough, there was liquid spilling onto the ground and fire coming from underneath. So we quickly got away from the car and called 911. Another gentleman who had been going West also stopped to make sure everyone was okay and was also calling 911. Within 10-14 minutes the front of the car was totally engulfed in flames.

Hello: My 2018 Pacifica hybrid was just recalled, and serviced, yet the hybrid battery only last a few miles before needing to be recharged. Also, when in reverse the back up camera doesn’t always come on and doesn’t beep when approaching an obstacle. It will also stay on while driving forward.

The shifter nob will not turn on and move out of park. When I open the glove box and tap on the CAN-C Bus star connector the nob will then turn on. Other issues also with electrical throughout van dealing with the CAN-C such as driving and then it shifts very hard. And door not closing on the side.

I had my Chrsyler Pacifica since Nov 2018 . Recently I heard a noise and Dealer suggested change in Transmission . Ever since I have problem with Car stopping im middle of road , towed 5 times to dealer and dealer says he fixed it but still same problem with vehicle stalling happen. yesterday (05/20), delaer informed that vehicle stalled in road while they did test drive after they fixed the problem. I am scared to drive this car anymore. Dealser did not want to loan their car as well anymore , I am without car for more than 30 days during this all 5 incidents .

After safety recall 73B was performed on my 2018 Chrysler Pacifica Hybrid on 02/03/2025, the vehicle's check engine light illuminated and it began experiencing charging failures. The component that has failed is the high-voltage (HV) battery pack and its control system. Diagnostic scans performed by a Chrysler dealer on [Date of diagnosis] confirmed trouble codes, including U0412, which indicate a critical fault within the battery system. The HV battery is available for inspection upon request. My safety and the safety of others are at risk because the recall was issued to prevent a battery fire. The symptoms my vehicle is exhibiting are precisely the kinds of faults the recall's software update is supposed to detect. By refusing to provide the full remedy, the manufacturer has left an unresolved fire hazard. The problem was confirmed by dealer diagnostic reports. However, both the dealer and Chrysler have refused to replace the defective battery under the recall. Their denial is based on [indicate reason for denial]. The first warning signs, including the check engine light, appeared within days of the recall service. This strongly indicates the recall procedure, specifically the mandatory battery integrity test, was not completed correctly by the dealership. This is a widespread issue, with numerous owners reporting the same post-recall failures online and to Chrysler Cares customer service.

Car will not start with push button and/or key fob push. Problem started 10 months ago with dead stop/start battery. Both batteries were replaced and then two months later stop/start system failed at stop lights. Car would stall once break was released to go. Had car serviced, starter replaced. Next day, car stalled and would not restart in parking lot, service department could not find any problems and no error lights found so the solution was to turn stop/start system off. A few months later car would not start on first try, took several pushes and sometimes a keyfob push. Sometimes "no key fob detection" light. Car was sent to service center again and they could not find any problems. At this time car only starts on 2nd push. Problem has worsened over the last 5 months, car takes at least 5 tries to start or doesn't start at all. Additional observations: brake gets very tight and pressurized after the first attempted start, steering wheel is locked.

After the 73B recall was performed on my 2018 Chrysler Pacifica Hybrid, the vehicle began experiencing persistent check engine lights and charging issues, especially during charging. Diagnostic scans revealed codes U0412 (invalid data from battery energy control module) and P0BBE (hybrid battery pack voltage variation), both directly related to the high-voltage battery system. These issues began within days of the recall and escalated, with the battery fault becoming permanent by late May 2025. The recall was issued due to a risk of fire from the high-voltage battery, caused by defects that can develop over time. The recall remedy included a software update to monitor for dangerous battery conditions and disable charging if a risk is detected, as well as inspection and replacement of the battery if necessary. My vehicle’s post-recall symptoms—persistent warning lights and charging faults—are exactly the type of problems the recall is meant to detect. The problem was confirmed by diagnostic data and scan reports, which were sent from the dealer to Chrysler’s technical support (STAR), but the vehicle itself was not physically inspected by the dealer or STAR. Both refused to authorize battery replacement, citing the contradicting STAR report, despite clear evidence of battery failure and the recall’s stated purpose. The battery and related components are available for inspection upon request. My safety and my family’s safety are put at risk, as the recall specifically warns owners not to charge or park the vehicle near structures until the remedy is complete, due to fire risk. Multiple other owners have reported similar post-recall battery failures, indicating a broader unresolved safety issue. Chrysler has not provided a satisfactory resolution, and the vehicle continues to exhibit battery faults and charging issues after the recall remedy.

The battery of my hybrid electric minivan was damaged during a recent factory recall, and Chrysler is refusing to correct the problem. Instead, they’re trying to charge me for a new battery. Here’s the background. I recently received a recall notice (73B) for my 2018 Chrysler Pacifica hybrid minivan that warned of a possible vehicle fire. I was advised not to recharge the van and to park outside and away from structures. In January, I took the van to Russ Darrow Chrysler in the Milwaukee Auto Mall to address the issue. The check engine light came on shortly after the recall work was complete (trouble codes U0412 and P0BBE). I took the van back to the dealership as soon as possible. I was told there was a serious problem with the high-voltage battery and that it may need to be replaced. Chrysler refused to authorize the repair, so the dealership cleared the codes and released the van back to me. On [XXX], the van lost all power while my wife was merging onto a busy highway. She managed to pull over, and we had the van towed back to the dealership. The van has now been at the dealership for over 4 months. Chrysler is still refusing to fix the problem. I have since learned that there are many customers experiencing similar battery failure following the 73B recall. The Pacifica Forums (link below) details over 80 customers experiencing nearly identical battery failures after bringing their vehicles in for this recall. My safety and the safety of others are at risk. The symptoms my vehicle is exhibiting are precisely the kinds of faults the recall's software update is supposed to detect. By refusing to provide the full remedy, the manufacturer has left an unresolved fire hazard as well as the risk associated with the sudden loss of propulsion.
