2020 Chrysler Pacifica: engine stalls while driving

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.

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.

The hybrid propulsion system on my 2020 Chrysler Pacifica Plug-In Hybrid has repeatedly failed, resulting in sudden and complete loss of power while driving at highway speeds. The vehicle enters full limp mode, displays a red turtle warning light, and the motor cuts out entirely, creating a serious collision risk. The failure occurs without warning and has happened on multiple occasions. The root cause has been traced through escalating component failures: first the Power Inverter Module (PIM) was found to have an internal failure disabling regenerative braking and causing the motor to cut out; subsequently the battery charging module was found to be failing, causing the high-voltage battery to drain to 0% and stall the vehicle. Both components were replaced by an authorized Stellantis dealership under warranty. Despite replacement of the PIM, the charging module, and ultimately the transmission, the defect has not been resolved. The vehicle has been confirmed defective by the authorized dealer on each visit and has been subject to a STAR (engineering escalation) case with Stellantis. Warning symptoms include the red turtle warning light, check engine light, and sudden power loss. The vehicle has been out of service for cumulative warranty repairs exceeding 130 days, including a continuous period exceeding 90 days. The vehicle remains unrepaired and in dealer custody as of the date of this filing. The dealer has confirmed the defect on each visit and has conducted multiple rounds of diagnostic testing and component replacement, none of which have restored safe and reliable operation. The component failures are available for inspection upon request.

The vehicle was purchased 8/5/2023. 8/23/2023 the vehicle stalled while at the bus stop with kids. Would not start again. 10/26/2025 the vehicle again stalled but at a red light during rush hour. During this event I attempted to use the hazards so the traffic approaching was aware it was not working. The hazard lights would not work. The vehicle was not even allowing the neutral position to allow it to be pushed out of the way. I was on the side of the road waving down card watching about 20 cars (fairly assuming with no lights indicating otherwise that it was moving) I was flagging traffic on my way home from a night shift at a hospital in town. I had it towed home was able to charge the battery enough for taking it to the dealership. The axillary and main batteries both were replaced more than 3 times. I had the vehicle for three years and this was an ongoing issue the dealership never disclosed there was a battery cable recall and turned me away from discussing they also did not disclose this year make and model had a class action lawsuit and recalls for the stop/start system failure. They refused to help or report my VIN number. In March of this year it did it again. To allow this vehicle to be on the road is dangerous. I voluntarily surrendered it with that being said and the lender (Flagship Credit Acceptance) Is attempting to sell the vehicle and also refused to acknowledge any calls out of many calls I made to report the vehicle is dangerous. Both businesses did not disclose the recall and the vehicle is currently in storage I believe and I'm worried a family will end up very hurt if not multiple as that day where I witnessed about 15-20 cars come very close to ramming the back of it head on because it was not able to be moved.

2020 Pacifica keeps stalling. From a stop light or stop sign the vehicle will lurch forward without warning. Recently, from a strip mall I stopped before pulling out into traffic and the vehicle lunged forward peeling rubber and shot onto the main road and I had to slam on the brakes to get the vehicle under control. At the next stop light, it stalled and I couldn't get it started. I'm handicapped and I had to exit the vehicle with my canes and advised the driver behind me of the problem. I've made 5 trips to the dealer with this problem. The dealer replaced a crankshaft postion on one trip and the fuel pump on another visit. If you leave the vehicle set for about an hour everything goes back to normal until the next time it stall, which is the next time I use the vehicle. More recently I picked up my vehicle from the dealer on February 14th, put 24 miles on it. I didn't use the vehicle on [XXX]. I then drove six miles on [XXX] for a total of 30 miles and it stalled again. The dealer South Hills Chrysler Jeep keeps telling me they can't duplicate what I'm telling them are the problems with the vehicle. I don't know if it is a transmission or what. I called Chrysler customer service and spoke with a man named Sahil. I explained the issues with the vehicle and he contacted the dealer and parroted what the dealer said to me, they can't duplicate what I am saying is wrong with the vehicle. This was on February 28th. My van has been setting at the dealer since February 18th and I haven't boo from the dealer since. Sahil is to call me tomorrow the 5th of March , but I don't expect any information from him that will resolve the issue. I am [XXX] and [XXX], I need this van for hauling [XXX} for doctor's appointments and other issues that surface. This problem of stalling started back on the middle of November, 2024, again the middle of December, 2024 and again the middle of January, 2025.

Auto stop and start failed while driving causing the vehicle to not start back up at a stop light when the light turned green. It took shutting the ignition off and restarting the vehicle to get going again. This created an unsafe situation in traffic that very well could have resulted in an accident due to the brakes being released and tail lights going out and the vehicle stalling instead of taking off. Had the driver behind me not been paying attention I would have been rear ended. Message currently displayed on dash shows auto start,stop disabled and needs serviced.

The transmission lurches or stalls. A check engine light will come on and says to service the transmission. While moving it will automatically detect a problem them engage the parking brake. While the check engine light is on, it will not go into gear. It will put itself in park if i try and out it in drive or reverse it just wont move. Has been going on since 6,000 miles and Chrysler constantly tells me there's no problem and it's normal. Now at 50,000 miles and it's still a huge issue. Chrysler has failed to document every time I've complained about it. Refused to give service records.
