2020 Chrysler Pacifica electrical problems

Filed Nov 2, 2026 · Electrical, Engine · IL

Over the past couple of years the auto start-stop system has progressively gotten worse with erratic issues. I've been to the dealership, and have replaced the main and aux batteries multiple times to reset the system and fix the problem. New batteries do not fix the problem. The vehicle's electrical system has turned off the engine and stalled multiple times in the middle of intersections. The vehicle has shut down twice while attempting left turns across lanes of oncoming traffic and three times pulling from a side street onto a major road. This has started to happen everyday and is posing a safety issue for my two young children, family, and other motorists. This electrical issue is a well known problem of this model and multiple calls to the manufacturer and the dealership leaves me in the middle where neither want to provide a path for assistance as the dealership explains my issue as a manufacturer problem. In the past 3 weeks the electrical issue has impacted the vehicles ability to consistently start, sometimes the engine won't turn over and I have to jump the vehicle on an increasing basis. The start-stop system has created further electrical problems where the start-stop dash signal is on constantly, the dashboard lights up sporadically, and today the vehicle would not unlock by using the key fobs and with no physical key I am not able to access the vehicle.

File an Immediate the federal safety agency Safety Complaint (Do This Tonight) The vehicle intermittently stalls completely while decelerating or braking at low speeds when the engine is warm. The dashboard flashes an ACC/FCW warning as the engine dies. This requires a full shift into Park to restart in active traffic, creating an imminent crash hazard. The vehicle has only 26,000 miles. Chrysler Case #98023933 is refusing to authorize diagnostic flight data logging or precautionary repairs because the dealer cannot immediately replicate it." •

My 2020 Chrysler Pacifica Plug-In Hybrid (VIN [XXX]) is covered by safety recall the federal safety agency 26V‑362 / FCA 52D (shown as "Recall Incomplete" on the federal safety agency's VIN lookup as of October 17, 2026), high-voltage battery fire risk. FCA advises owners not to charge the vehicle and to park it outside, away from structures, until it is repaired. FCA's dealer notice states the remedy for 2020-2021 model-year vehicles became available June 12, 2026. Shortly before drop-off, the vehicle's electronics began failing intermittently; no battery warning messages appeared and there was no fire. I purchased the vehicle from Clay Cooley CJD Ram (Irving, TX) on November 27, 2020. I presented it to Meador Chrysler Dodge Jeep Ram, Fort Worth, TX on August 18, 2026 (repair order [XXX]) for this recall. As of [XXX], 65 days later, the recall repair has not been completed and the vehicle has not been returned. The dealer has provided no status updates. The dealer provided a loaner that is far below the Pacifica in quality, with much worse fuel economy. Under 49 U.S.C. 30120(c), failure to repair within 60 days after presentation is prima facie evidence of failure to repair within a reasonable time. I request that the federal safety agency look into FCA's remedy timeliness and parts availability for this campaign, including replacement battery packs, which FCA's remedy instructions say are ordered through its STAR Center only after approval, and whether FCA has met its remedy obligations for this vehicle.

I took my 2020 Chrysler Pacifica Hybrid (VIN: [XXX]) to Sames Bastrop Chrysler Dodge Jeep Ram in [XXX], to have Safety Recall 52D performed on the high-voltage battery. Prior to bringing the van in, the vehicle was driving and charging completely normally with no charging errors. Sames performed the recall software update to the Battery Pack Control Module (BPCM) under Recall 52D, but their diagnostic scan logged an active high-voltage fault code (DTC P0E15-00 for the battery pack coolant heater) and a stored bypass valve code (DTC P0E7C-00). Despite these active thermal management codes showing up in their system, the technician marked the vehicle as passed and returned it to me. After driving the van home the vehicle completely refused to charge on my very first attempt at home. The dashboard displayed a "Service Battery" warning message, and the charging system has been completely locked out ever since. This is a serious safety concern because the high-voltage battery recall was issued specifically to prevent battery fires and thermal runaway caused by internal cell defects. Returning a hybrid vehicle with an active thermal management failure during a fire-related recall leaves the battery vulnerable to overheating and disables the charging safety systems. The van was returned to [XXX], where it has sat for over a month. Sames initially stated that Stellantis was refusing to cover the battery replacement even though federal law requires safety recall remedies to be completed free of charge regardless of mileage. The charging failure and trouble codes have been confirmed by the dealership under Repair Order #XXX. I have also opened an active corporate case directly with the manufacturer under Stellantis Case #XXX, and Sames has provided a temporary rental vehicle through Enterprise while this is investigated. The van and all of its original high-voltage components are currently in the service bay at [XXX]. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I experienced a sudden loss of power and steering while driving my vehicle. The screen advised me to pull over because the engine would shut off soon, but I already had lost steering and power. I turned the car off and was able to restart it and drive it 1 mile home, and the check engine light was on. I had it towed to the dealer. After 2 weeks of testing, the dealer reported, “When your vehicle was initially checked in, the following trouble codes were present: 5 BPCM FAULT CODES P1A21-00, P1D43-00, P1C01-00, P1A2A-00, and P1A29-00. We have completed Recall Y40.” The repair tech said they expected the engine to lose power again at some point and I would need to have it towed in again to be repaired then. The repairs made so far are only software updates, no hardware has been repaired because the dealer said the errors didn’t recur after they reset the system. I have elevated the issue with the dealer and am awaiting a response. I am concerned based on the error codes and technician information that my vehicle is still at risk of catching fire at any time or experiencing another catastrophic loss of power if the faulty hardware is not replaced.

We own a 2020 Chrysler Pacifica Hybrid that had been operating without any significant issues for approximately six years. Recently, the vehicle was subject to a recall involving the charging system, and we brought it to the dealership to have the recall work completed. Nine days after the recall service, the vehicle would not start and displayed a “Service Charging System” error message. The dealership arranged to have the vehicle towed back for evaluation. They kept the vehicle for approximately a week and a half but ultimately stated that they were unable to identify any problem. We were charged $200 for the diagnostic evaluation, and our insurance covered the cost of the tow. Approximately 10 days after receiving the vehicle back from the dealership, it again failed to start and displayed the same “Service Charging System” error. Given that we had no significant issues with the vehicle for approximately six years and that this problem began only nine days after the recall work was performed—and has now occurred twice—we are very concerned that the issue may be related to the recall service or that the underlying problem was not identified during the dealership’s initial evaluation.

Vehicle has suffered from electrical issues since 2023 with effects to front windows causing window to reverse down when trying to roll up, radio malfunctions that is a known Chrysler issue that removes the ability to control rear entertainment center from front screen leaving the feature unusable with small children in the rear for long periods of time, rear cross traffic warning detection malfunctioning and not making audible alarms or warning with vehicles and pedestrians behind vehicle, loud noises when braking that according to Chrysler TA is potentially the ABS system wanting to engage but didn't, electrical shorts causing intermittent surging of interior lights - slower functioning of sliding doors - shorted out multiple window washer pump systems leading to replacement - lane departure system malfunctioning causing vehicle to drastically steer vehicle towards a curbed center island in which I as the driver had to manipulate the wheel to avoid crashing - passenger slider door at time malfunctions causing the door to repeatedly open and close on it's own and also open on its own while vehicle was underway in reverse - blind spot monitoring system malfunctioning at times to not warn of vehicles in blind spot - vehicle stalled twice with check engine light on but no recorded data in computer of the events ever occurring. All of these issues have been inspected under both factory warranty and extended Mopar warranty with service department stating they could not replicate the error and no further investigation or diagnosing was completed. After "repair attempts" were made the malfunctions reoccurred with another service appointment being needed and more electrical errors happening over time. Per service department there were no DTC or check engine lights for our malfunctions, however years later they finally admitted there had been DTC logs but were ignored and not diagnosed. We feel the safety of our family and public are at great safety risk from the failures.

I purchased my 2020 Chrysler Pacifica in January 2020. By April 2021, I began experiencing ongoing issues that have never been fully resolved. In the six years I have owned this vehicle, I have gone through six batteries. The vehicle has stalled in the middle of the road and, at other times, has failed to start altogether. The vehicle also does some jolting randomly which can be very harsh to the passengers inside. I specifically purchased this vehicle because of its safety features, as I have young children. Unfortunately, these repeated failures have left me feeling unsafe and concerned about the reliability of the vehicle. Each time I have brought the Pacifica to the dealership, the battery has been replaced or recharged and I have been told the issue was fixed. However, within six months to a year, the same problem returns and the vehicle is back in the shop. The issue has occurred again, and I am at a loss as to what to do next. It is clear that there is an underlying problem that has not been properly diagnosed or repaired. After six years of recurring breakdowns and unsuccessful repair attempts, I have been unable to fully enjoy or rely on this vehicle. I am requesting that this matter be taken seriously and that a thorough investigation be conducted to permanently resolve this ongoing issue. Given the repeated repair history and the safety concerns involved, I believe this situation warrants immediate attention.

When driving on highway, electrical system started beeping and showing various signals, could no longer keep speed or accelerate. Had to put on warning lights and coast to side of road with four small kids in car. Was able to pull off to side and slowly get to safe location by resting vehicle in between events. When fully charged, didn’t seem to have issue so was able to drive to dealer. Thought was related to engine switching from electric to gas power. Dealer checked and performed two software updates. On way home from dealer, same problem occurred on highway. Super dangerous to loose all acceleration or same speed on highway! I got a video of second event as I was a passenger and my husband was driving. But as can see in video the car has a charge so the incident is not related to the switch from electric to gas power. Now we are very concerned whether Chrysler has the means to fix this at all and or whether the dealership will be actually able to identify the issue given the car was literally being driven home from the dealer. Attaching photos but have a full video. First time happened on April 4, 2026. Second on April 16, 2026
