2020 Chrysler Pacifica Powertrain & Transmission Problems

The start/stop system fails while car is running. Power not delivered appropriately resulting in check engine light coming on and entire car shaking. Only 62k miles. Started at 58k.

I purchased this van in March 2025, it was used about 62000 miles, but dealer said it was in good condition, no issues. In September 2025, a battery light came on, that also activated the Start/Stop could not be used and needed service as well as Service Shifter. I brought the vehicle in and they simply replaced the auxiliary battery and sent me on my way. On November 13th, I was driving and a battery light came on as well as the Stop/Start not available error, and then moments later said "Stop Safely Vehicle will shut off soon". Thankfully I was only moments from home, and made it safely with my 5 children who were also in the van. Obviously this is dangerous as the vehicle stopping while driving can kill myself, my children, anyone in my vehicle, as well as cars around me as I live in a busy area, Tampa, FL. This car had just been given a review in March when put up for sale, and I had brought it in for an oil change, as well as a motor mount replacement, and the aux battery change, before this. My car has been serviced multiple times and this should have been checked or errors/updates reviewed. This auto/stop start seems to be a key in the safety issues as well since that light comes on every time there is an issue. Now the dealer states they are going to replace my PDC, main fuse box, and see if that fixes the error, but I have read that this is an error in many Chrysler Pacificas and mine is another.

Component/System: The propulsion system of my 2020 Chrysler Pacifica Hybrid, specifically a suspected internal transmission wiring-connector short—the exact hardware defect identified in Recall 23V-010 as capable of causing sudden loss of motive power. In my case, both propulsion sources (gas and electric) simultaneously ceased providing power, leaving the vehicle unable to accelerate. The vehicle, its transmission, and all hybrid-system components are available for inspection upon request. When inspected at the Chrysler dealership, technicians retrieved a diagnostic trouble code they acknowledged corresponds to the known wiring-connector short condition. This code was present before any recall procedures were performed. Safety Risk: I was traveling at highway speed with my family, the vehicle abruptly lost all motive power and began decelerating without my ability to maintain speed. I was forced to coast to the shoulder while surrounded by faster-moving traffic, exposing me and other motorists to the danger of a high-speed rear-end collision. Dealer Confirmation: The Chrysler dealer confirmed the presence of the wiring-connector-related fault code and agreed that it aligned with the recall defect pattern. However, they performed only the software update required under Recall 23V-010 and informed me that they would not undertake further inspection or physical diagnosis unless I paid out-of-pocket, despite the safety-critical nature of the failure. They are ignoring the fact that the physical underlying defect is not fixed by the software update, much to my frustration. With this unfixed, the car is not safe to drive IMO. Inspection: The vehicle has been inspected by an authorized Chrysler dealer. No additional parties have inspected it. The dealer did not examine or repair the wiring harness or connector itself, refusing my request to do so. Warnings/Symptoms: A hybrid/electrical-system warning message appeared moments before the shutdown. No prior symptoms

This submission supplements my prior NHTSA ODI complaint regarding the same vehicle and loss-of-motive-power condition. On Nov 8, 2025, the vehicle experienced a loss of propulsion at highway speed, creating an immediate safety risk. The vehicle could not maintain speed and required evasive action with no propulsion to avoid traffic hazards. Following the incident, the vehicle was inspected and stored diagnostic trouble codes P0A3F-00 and P0A43-00 were retrieved, relating to drive motor position sensor / resolver signal loss or degradation. These fault codes are associated with loss of propulsion and indicate a propulsion control signal-path fault, rather than a condition resolved by software calibration alone. The vehicle remains available for inspection and is out of service at a dealership due to unresolved safety concerns. Since my prior ODI complaint, I provided formal written notice to the manufacturer describing the incident, the retrieved fault codes, and the safety implications, and requested a written response. Receipt was confirmed by USPS certified mail on January 6, 2026. No written response was provided, and repeated attempts to contact the manufacturer through customer service channels were not returned. The manufacturer authorized only a recall firmware update and declined to authorize or perform the intermittent wiring and resolver diagnostics identified in its diagnostic procedures for these fault codes. The firmware update does not inspect, repair, or replace the resolver, wiring, or related hardware indicated by the stored codes, and does not determine whether the underlying propulsion fault has been corrected. As a result, the vehicle has been out of service for more than two months, and the risk of another loss-of-propulsion event remains unresolved. This update documents the manufacturer’s non-response after notice and reliance on a software-only remedy that does not address the indicated propulsion system fault.

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 entertainment system when super cold outside the screen goes black and does not work. The issue has made it difficult then to change heating and cooling settings and utilize the rear view camera and other safety features of the car. The dealership was able to update it to fix it once then the other two times it came back on before the appointment for the dealership. The auto/stop start malfunctioned while waiting at light.putting my whole car in park and locked up until I turned it off and back on. This occurred twice and put me at risk with being on busy roads in the day. Dealership was able to fix with a new battery. In the past and currently the car has shifted with a Jerk or lunge type movement making the driver worried and concerned about hitting cars around them due to this. The dealership replaced a transmission gasket but still does this and have not been able to find the issue on 3 other occasions. The car also is now not shifting properly creating a low humming grind type sound when driving on the highway and the brake pedal feeling weird. This has delayed speeding up and slowing down creating major safety concerns when driving on the highway. The dealership has not been able to replicate yet due to only driving on town roads and not the highway at this time.

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.

I came to a stop at a stop sign yet again & the emergency brake engaged & put the car in park & shut itself off. I’ve lost count of how many of these forms I’ve filled out & how many times it’s happened and NOTHING IS GETTING SOLVED!!

My van once again gave the stop safely, vehicle will shut off soon & stopped right in the middle of the intersection. I’ve lost count on how many times this has happened!!

I’m experiencing persistent issues with my 2020 Chrysler engine. While driving, the engine frequently shuts down unexpectedly, often resembling a start-stop feature. When I come to a stop, the engine and lights go out, and the vehicle won’t restart, which is particularly concerning while in traffic. Additionally, when accelerating, I notice a jolt in the engine followed by a loud knocking sound. These problems significantly affect the vehicle's performance and pose a serious safety risk. I would appreciate any guidance on diagnosing and resolving these issues.

See attached document for complaint.

I have a 2020 Chrysler Pacifica Hybrid that has had transmission issues since 2022. I have taken it to the dealer 8 times for repair for the same transmission issue. In August 2022, the vehicle shut down on the interstate while driving. It was determined that it needed a new transmission after just two years. The vehicle was with the dealer for over 30 days awaiting a new transmission. Once the transmission was replaced, there was a battery issue in February 2023. In January 2024, the vehicle went into limp mode again, for the first time after the transmission was replaced. Repairs were attempted at the dealer. I have continued to have issues throughout 2024. In July 2024, the transmission wiring harness was replaced. The vehicle has gone into limp mode three more times since then. On 14 September, the most recent time the vehicle went into limp mode on the interstate, I took it into the dealer, and it was determined a second transmission replacement was needed. Chrysler has now issued a lifetime warranty on the transmission. It's only a matter of time before significant injury or loss of life occurs because of the transmission issues, especially because they normally occur only at higher speeds on the highway. Clearly, installing a third (or fourth or fifth) transmission will not fix the issues in this faulty vehicle. When I contacted Chrysler Cares yesterday I was told that because the transmission will be replaced for only the second time, I do not qualify for a buyback. However, it has been to the dealer to be serviced 8 times and was there for over 30 days during the first transmission replacement.

Vehicle sudden loss of power 3x in 3 months. Van has known recall for loss of power/possible transmission problem. Traveling 30-50mph for 20 minutes, start of morning temps 70 degrees, recall warranty (update was software to warn driver of power loss on screen) done and 1 month later began power loss. Screen reads "Stop Safely Vehicle Will Shut Off Soon", engine light on, red turtle light on. Loss of power would not warn drivers to rear of slow down since brakes are not pressed promoting rear end collision, highway speeds slow down causes traffic and collision with limited place to exit safely, loss of power would not allow driver to exit traffic thus causing danger , obstacle for other drivers to avoid. Vehicle at dealer for software update: May 2024 , 3x power losses after, 9/2024 returned to dealer, currently in service at dealer Data Source: Recall 23V010, Office of Defects Investigation (ODI) opened investigation PE22-008 regarding complaints alleging a loss of motive power condition potentially due to a transmission malfunction in Model Years 2019-2021 Chrysler Pacifica Plug-In Hybrid Electric Vehicles (PHEV

Power steering has failed on 2 occasions while driving. Fault code was set and dealer confirmed fault codes using scan tool. Power steering returned after a few seconds of driving. This vehicle has an electric power steering pump. Fault code listed a communication failure between the power steering controller and body ecu. Dealer service department could not duplicate the problem and returned the vehicle to us saying there was nothing further they could accomplish. It is a dangerous situation losing power steering while driving. Warning icon did appear on our on screen driver display.

The contact owns a 2020 Chrysler Pacifica. The contact stated that while stopped at a stop light, the vehicle inadvertently lost motive power; however, the vehicle was able to be restarted. After restarting the vehicle, the vehicle returned to normal functionality, but the failure became a regular occurrence. The contact stated that several unknown warning lights were illuminated. The contact also stated that later, while driving at 40 MPH and attempting to accelerate, the vehicle briefly hesitated and jerked before returning to normal operation. The vehicle was taken to the dealer, who was unable to determine the cause of the failure. The vehicle was not repaired, and the failure reoccurred. The vehicle was taken back to the dealer, who diagnosed a failure with the transmission control module and performed a software update as per Technical Service Bulletin: 21-043-20. The vehicle was repaired, but the failure reoccurred. The manufacturer was not notified of the failure. The failure mileage was 70,000.

It’s the same issue that the hybrid pacificas were recalled for. It pops up the random stop safely on the dash & then you’re halting to a dead stop & the vehicle shuts off. This has happened several times.

In August 2022, while traveling on the interstate I received a warning that the vehicle was experiencing a power failure. It subsequently shut down while traveling at highway speeds. I was able to navigate off an exit that happened to be immediate and coasted downhill off the exit ramp to a safe spot. I was unable to power the vehicle off for approximately 10 minutes. Once able to power the vehicle off and keeping it off for a few minutes, I restarted it. The check engine light was lit but drivable. The dealer replaced the entire transmission. In January 2023, the dealer completed the recall associated with the vehicle. On 1 January 2024, while driving approximately 60mph, I received notice that the vehicle would shut down and to pull over safely. Upon turning the vehicle off and back on, the check engine was lit but drivable. The vehicle is currently with the dealer again.

On 11/05/2023 at approximately 12 pm while getting onto the highway of 183 in Austin Texas @ Lamar increasing speeds from 45 to 65mph the engine shifted hard 3x. The engine surged then a hard shift. This occurred 3x. I’m certain you understand the complexities of austin Texas traffic. No matter the time of day. Imagine those complexities with a car that was poorly made by a company that has never been held accountable.

Exceedingly jarring transmission shifts at both low and higher speeds that are startling to the driver and could cause an accident. This has been a chronic issue that happens frequently but not in every use of the vehicle. Below is a date in which this recently occured.
