Chrysler Pacifica won't start problems

Filed Nov 2, 2026 · Electrical, Engine · PA

I originally took my car to Reedman toll in 2021 due to frequent issues with the batteries needing to be replaced and the car not starting. At the time I was told it was related to a recall, and they fixed it. However, over the last year I have continued to have various problems with the car. The batteries were replaced numerous times. The check engine light and stop start unavailable light going on randomly. The car also started having electrical issues like the radio would just turn off on its own, or the automatic car doors would not open. The car also started feeling jumpy and shaky upon starting, and when the car is off there is a thumping noise. This thumping noise is still heard when the car has been off and parked for hours. The car will be off and I will get in it and hear the thumping before the car starts. Over the summer the problems became more frequent, and on August 31st it would not start, and I had to have it towed to Reedman. Reedman said my started was bad and also the fuse box shorted. They had my car for 10 days, and during this time I paid $500 out of pocket for a rental. I paid $2000 to Reedman for these repairs. I got the car back, and immediately (same day) experienced the exact same problems, and then my car would not start again. When I did get it started I kept getting warnings that the engine might overheat. I got it back to Reedman and they then said it was a bad alternator and some wires were bad as well. They had my car for 2 months. I picked it up 9/30/26 and within less than 6 hours the check engine light and start stop unavailable light came on. The car started feeling jumpy again upon starting, and the thumping noise returned. This car was purchased brand new in 2018 and only has about 51,000 miles on it. I do not understand why this is all happening to a car that has such low mileage. My 2014 Nissan has never had a single problem.

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.

On 8/16/26, my 2017 Chrysler Pacifica Hybrid would not start after being parked for several hours in an underground parking structure in downtown Detroit during a baseball game. There were no warnings before the failure. The vehicle was towed to Serra Lake Orion at a cost of about $700. The dealer found diagnostic trouble code P0AA1 (hybrid/EV battery positive contactor circuit). The high-voltage system is locked down and the vehicle cannot be started or driven. The vehicle has been at the dealer since August 18, 2026, and as of 10/1/26 has been out of service for about 6 weeks. The dealer has an open Chrysler STAR technical support case (102974656) seeking approval to replace the high-voltage battery, and the process has involved repeated requests for additional testing. I have been given loaner vehicles during this time but am approaching the mileage limit on the second. The vehicle has about 220,000 miles and I have owned it since August 2017. It has no open recalls. It previously received recall repair work on the hybrid system, including the power inverter module recall (Chrysler T34 / the federal safety agency 17V‑371), which included reprogramming of the battery pack control module. I understand this model has also been subject to other high-voltage battery recalls. I am reporting this because a high-voltage contactor failure that leaves the vehicle unable to start or move can strand occupants, in this case in an underground parking structure, and because the repair has been delayed for more than 6 weeks. The root cause has not yet been determined by the dealer or manufacturer. I would appreciate the federal safety agency tracking this failure alongside other Pacifica Hybrid high-voltage battery complaints.

Vehicle: 2022 Chrysler Pacifica Hybrid. Approximately 25,300 miles On Saturday 9/12/26 while driving at highway speeds the following message displayed "Stop Safely, Vehicle Will Shut Off Soon". When the message displayed the check engine light illuminated as well as the limp mode light. In limp mode the vehicle reduced speed rapidly and would not accelerate above 20 MPH. This happened at highway speeds on a multilane highway. We were able to get to the shoulder, but it was very dangerous changing lanes in limp mode. Turning the vehicle on and off several times cleared errors except the check engine light. We were able to get off the highway and get home without the message or limp mode triggering again. The check engine light stayed illuminated for 24 hours and went off when I refueled the vehicle the next day. For the next week I drove at local speeds with no issues. On Saturday 9/19/26 the vehicle would not start. This is a plugin hybrid and was fully charged. The electric motor would not start, and the check engine light illuminated again. I turned the vehicle off/on 3 times to get it to start. I did my errand and returned home. When I returned home, I turned the vehicle off then on again and the check engine light cleared. On Tuesday 9/21/26 I dropped the vehicle off for service, getting there without issue. The dealership stated the transmission will need to be rebuilt. Problem code is P0A43-00. This is the SECOND transmission failure since ownership. I've had the vehicle serviced only at the dealer where purchased. The dealership confirmed the FIRST incident with the same problem code was diagnosed on 1/30/24. The transmission was replaced at this time. The van had 12,134 miles. The 2024 incident also was triggered at highway speeds. If my memory is correct, I believe I reported the first incident to the nthsb at the time.

On 7/16/26 vehicle would not start; high-pitched noise heard near engine during no-start diagnosis. Towed to Goldy Chrysler Dodge Jeep Ram, Huntington WV. Per dealer invoice #27136: blown 500-amp main battery fuse found; after jumping past fuse, white smoke from exhaust and no coolant in system, diagnosed as blown head gasket. Repair: both-side head gasket replacement plus fuse assembly. Vehicle in shop 7+ weeks, returned 9/4/26 with new unresolved issue: strong smell of burned electronics and antifreeze in cabin. All failed components available for inspection upon request. Safety risk: head gasket failure/coolant intrusion caused engine hydrolock, a sudden uncommanded loss of engine power that can occur without warning, including while driving in traffic. Burned-electronics smell raises electrical/fire risk; antifreeze odor raises cabin fume exposure and window-fogging visibility concerns. Confirmed by dealer: Yes. Goldy diagnosed and documented the fuse failure, coolant loss, and head gasket failure in writing, and performed the repair. Manufacturer/police/insurance inspection: Not by police or insurance. Spoke by phone with a Chrysler HQ rep 5 times (8/13-9/1/26) who was informed; no confirmed independent physical inspection by manufacturer beyond dealer's own diagnosis. Warning signs: P0304 misfire on cylinder 3 appeared first, progressing to complete no-start with high-pitched noise, prompting the tow-in and hydrolock diagnosis.

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.

My 2019 Chrysler Pacifica Plug-In Hybrid unexpectedly rolled after being parked in my residential garage. The van has very low mileage ~60000 miles and is still under Battery Manufacturer warranty. The vehicle had been operating normally and was parked with P displayed on the instrument cluster. It remained unused for approximately 6 days. When the garage door was opened, the vehicle unexpectedly rolled several feet. I believe the closed garage door may have prevented it from moving earlier. A family member who happened to be present stopped the vehicle before a potentially more serious incident occurred. The vehicle and garage door were damaged. Afterward, the vehicle would not start/enter READY mode. The P indicator flashed, selected gear indicators flashed, and “Service Transmission” appeared. The vehicle ultimately required towing. An independent diagnostic scan identified multiple faults, including P07B5-00 (Park Pawl Position Sensor 1 Circuit Performance), P1625-00 (Park Pawl System Failure), and P0AA4-00 (Hybrid/EV Battery Negative Contactor Circuit Stuck Closed). Stevens Creek Chrysler later verified P0AA4-00 as ACTIVE. Their initial reset/weld-check procedure failed and the DTC returned. The dealer then opened Chrysler STAR Case 102963024. Chrysler Technical Assistance provided a PIN/procedure, after which the reset succeeded and vehicle operation was restored. The vehicle was subsequently road-tested and returned to me. However, neither Chrysler nor its authorized dealership has explained why a vehicle parked with P indicated was able to roll, whether the Park-related DTCs were connected to the incident, or whether the condition could recur. I am reporting this because an unexplained rollaway of a parked vehicle presents a serious safety risk. I remain concerned whether the vehicle is safe to park and whether similar incidents may affect other Pacifica Hybrid vehicles.

My vehicle has developed an intermittent and potentially serious safety-related failure. When the Engine Stop/Start system automatically shuts the engine off at a red light or stop sign, the vehicle sometimes fails to restart. At the same time, the electronic gear selector becomes locked, preventing me from selecting Neutral or moving the vehicle out of the roadway. The vehicle is therefore effectively immobilized in traffic. The only recovery method I have found is to disconnect both the main and auxiliary batteries for approximately 10 minutes, reconnect them, and then restart the vehicle. The check-engine light also comes on when the failure occurs. Both the main and auxiliary batteries have already been replaced on August 3rd, 2026, so this is not simply a matter of replacing an old battery. I brought the vehicle to the dealer on August 14, 2026 for inspection. Because I had previously been forced to disconnect the batteries to recover the vehicle, no diagnostic trouble codes were available when the dealer performed its inspection. I understand why this makes diagnosis more difficult, but the absence of codes after the system has been reset does not eliminate the underlying intermittent failure. I am particularly concerned because Chrysler has issued service information addressing closely related problems on the 2018 Pacifica, including S2008000075, concerning no-start, Stop/Start inoperative and Service Shifter conditions, and PCM bulletin 18-001-19, which addresses 2018 Pacifica conditions involving engine restart performance, battery state-of-charge performance, improper powerdown, ECU performance, and TCM/shifter communication faults. My vehicle also previously received the Y65 Engine Stop/Start campaign in 2021. Now in persistent no-start condition remaining in the failed state and can't be reset. The instrument panel powers up, the check-engine light remains illuminated, the vehicle produces a click when the Start button is pressed.

Engine only stalls out when stopped on roadway while driving. Vehicle also does not start up after it has been driven and is parked. It takes 10 minutes or longer to get the vehicle to start again. Check engine light comes on every time when these two situations happen, which it happens periodically. Sometimes it's 2-3 times a day, sometimes, once every two days. Once it starts back up the engine light turns off. I've taken it to 2 reputable shops and neither of them found any issues as they could not replicate the issue, the engine light is not on, and there are no codes displayed. I now have a date for a inspection which includes a test drive with the dealership.

I purchased a used 2018 Chrysler Pacifica with the 3.6L V6 F DOHC 24V engine in October 2025. The van had 97,000 miles. Shortly after I purchased it I noticed the engine had a rough idled. It now has 107,000 miles and the rough engine has continued to get worse. What I noticed is when I first started it the engine was rough and vibrated. Once I started driving it was not as noticeable. I decided to take it to a mechanic to see what the issue was. I thought it could be electrical. Before I could get it to the mechanic it would not start. I had it towed to the dealership I bought it from and the y confirmed that it is the head gasket. They told me they would approach Chrysler to see if they would help with the repairs, they said NO. The dealer did offer to bear part of the cost of the $4,000+ cost for the repairs. I do not understand how reputable company can manufacture a product that obviously has a flaw and deny support. I understand that their warranty is limited by time and distance. But from what I have read from the MANY complaints on the particular engine from 2018 it appears the issue arrises at 90,000 to 110,000 miles.
