2020 Chrysler Pacifica electrical system problems

“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…”

“File an Immediate NHTSA 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 NHTSA 26V-362 / FCA 52D (shown as "Recall Incomplete" on NHTSA'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 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…”

“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…”
