I was driving at highway speeds when the vehicle issued a warning to immediately stop before vehicle shuts down in 2 minutes. This presented a very dangerous situation trying to get off of highway surrounded in traffic quickly, and being stuck on a highway shoulder with trucks passing us at 70mph. An emergency roadside technician checked the engine light code to be POA43. Chrysler will not fix the car however because they state that the code didn't come from their dealership technician.

While driving, the vehicle suffered a sudden, severe, and un-commanded complete loss of propulsion and motive power on a live roadway, posing an immediate crash hazard. * Sequential Fault Chain: 1. An audible, physical "pop" was heard emanating from beneath the engine bay/high-voltage system compartment. 2. Immediate loss of acceleration and propulsion. 3. Simultaneous illumination of the Check Engine Light, a "Service Charging System" warning message, and a "Turtle" (absolute critical limp-mode)...

dashboard icon. 4. Electrical failure cascading to the interior control panel and displays, which flickered and went entirely dark while the vehicle was still rolling. 5. Abrupt, un-commanded physical engagement of the Electronic Parking Brake (EPB) as the vehicle slowed down, locking the rear wheels on a live road. 6. Total electrical blackout, rendering the hazard lights completely inoperable and leaving a dead vehicle entirely un-illuminated in active traffic.
When driving on freeway the vehicle overheated and engine warning light flashed and had to come to stop at side of freeway. The vehicle had lost its coolant from a rear heater hose connection. The car was towed to dealer and the repair comment was that a part was deformed from mis-assembly (or words to that effect) - rear heater core fitting clip distorted causing hose come of the core. This was an early life failure.
While I was driving to drop my kids to school My Chrysler Pacifica PHEV dashboard chimed, the check engine light made an appearance, and the screen in my gauge cluster showed a large warning message. "Stop Safely, Vehicle Will Shut Off Soon." I kept my foot in it and guided the Pacifica Hybrid through the off-ramp and into the rest stop's parking lot And turned off the ignition and engine for 5 minutes and I started the engine and car allowed me to drive back home . The power tram warning got away that evening when...

I started my engine . The same problem came back again many times since then. I googled it and found that this is very serious problem which may lead fire .i would like to report this issue now.
This is what I wrote to Stellantis. Dear Stellantis Customer Care, My vehicle has now stalled five separate times while I was making a left turn through an intersection. When this happens, the engine shuts off unexpectedly, the vehicle shifts into park and I must attempt to restart it while sitting in the roadway. During the most recent incident, the vehicle would not restart on the first attempt and required a second attempt before it would run again. This creates an extremely dangerous situation. Losing...

power in the middle of a left turn places me, my passengers and other motorist at risk of a serious accident. The vehicle has approximately 43,000 miles and has been taken to my Chrysler dealership for diagnosis. Unfortunately, I have repeatedly been told that they cannot duplicate the problem and therefore cannot repair it. Despite those visits, the dangerous condition continues to occur. I am requesting that Stellantis immediately: • Open a formal case regarding the safety issue. • Assign a regional field engineer, or star technical specialist to inspect and diagnose my vehicle. • Work directly with my dealership to determine the cause of this intermittent stalling condition. • Advise me whether the vehicle is safe to drive while this issue remains unresolved. I have been a responsible owner and have sought assistance through the dealership, but I cannot continue driving a vehicle that unexpectedly shuts off in the middle of an intersection. I am asking Stellantis to take this matter seriously, and provide a timely resolution before someone is seriously injured. Please contact me as soon as possible regarding the next steps. I would appreciate receiving a case number and the name of the representative assigned to assist with this matter. I intend to file a safety complaint with NHTSA regarding this matter. Thank you for your prompt attention to this urgent safety concern.
I have been experiencing random engine shutdowns since April 6, 2026. I've taken it to be serviced for this on four occasions since this time and it has not been appropriately fixed. There is a warning light that flashed before it happens that says "your car is about to shutdown, please pull over" but it does not allow ample time to pull over safely before randomly shutting down. The dealership replaced the PCM in may 2026 but I had the car back less than 24 hours and it happened again. The car has shutdown a total of 5 times since April 6, 2026.
2024 Chrysler Pacifica completely shutdown during a left turn. Engine died all electrical stopped functioning. Had to restart the vehicle to move the vehicle. This condition happened twice last week, but has not happened since. Fortunately it was a low speed situation rather than at highway speeds. Highway speed could have been a very serious situation with the potential of being rear-ended from high speed traffic. Vehicle has 27,500 miles on the odometer and was driving normally prior to the shutdowns. Chrysler dealer has been notified of the situation, but an appointment is 7-10 days out. No warning lights or messages were noticed.
On June 14, 2026, one day after purchase, while driving through the Mojave Desert on I-15 in temperatures exceeding 100 degrees Fahrenheit, the check engine light illuminated and remained on through Southern California. The vehicle required a jump start after being parked in a covered multi-level parking structure for 5 days in Long Beach California after which the check engine light cleared. On June 19, 2026, six days after purchase, during the return trip the high voltage hybrid traction battery failed completely...

without warning in active Las Vegas highway traffic. The vehicle lost all motive power and coasted to the roadside. Three minor passengers were aboard, the youngest age 13. The occupants were stranded in temperatures exceeding 100 degrees for approximately two hours awaiting a tow truck. The vehicle was towed to an authorized Chrysler dealership where the high voltage traction battery was confirmed failed and replaced under warranty. A valley pan oil leak was also discovered and hybrid software update were also performed. An outstanding curtain airbag safety recall had never been remedied prior to the breakdown. The towing company reported they had been towing multiple Pacifica hybrids with similar failures during the same Las Vegas heat wave, suggesting a systemic issue with the high voltage battery thermal management system in extreme heat. The vehicle had been purchased six days prior with fewer than 1,000 miles of ownership at time of failure.
I am a full-time power wheelchair user with Multiple Sclerosis and rely on this 2024 Chrysler Pacifica wheelchair-accessible van as my primary means of transportation. Since purchase, the vehicle has repeatedly experienced dangerous loss-of-power events while being driven. Immediately before the failure occurs, warning beeps sound and multiple warning lights illuminate, including Check Engine, ETC, Park Brake, FCW, ESC, and MIL. After these warnings appear, the vehicle loses acceleration and enters a...

reduced-power/limp-mode condition. Pressing the accelerator does not result in normal acceleration, creating a serious safety hazard in traffic. Most recently, on June 4, 2026, this occurred approximately six times during a single trip. During one incident, the warning lights illuminated, the vehicle lost acceleration, and we were forced to pull over with emergency flashers activated in a dangerous location. A police officer came upon us, stopped to assist, and advised that the location was extremely dangerous. Because I use a power wheelchair, I cannot safely transfer into a standard vehicle, taxi, rideshare, or other transportation. We explained to the officer that if the van were to be towed, I would effectively be stranded because there was no practical way to transport me in my power wheelchair. The condition later cleared and we were able to continue. The vehicle has been inspected multiple times by Chrysler service departments and DriveMaster, the local mobility provider working with Freedom Motors. The problem has been reported repeatedly but is intermittent and has not been reproduced during inspections. Despite multiple repair attempts, the problem persists. The vehicle is available for inspection. These recurring loss-of-power events create a serious safety risk for myself, my family, and other motorists.
Purchased vehicle through Carvana with approx. 21,504 miles on 4/1/2026. On 5/5/2026, with only 22,269 miles, the dashboard lights came on and informed us that vehicle will shut off soon and to stop safely. We were traveling 75 mph down the highway. We had it towed to a Chrysler dealer. They couldn't find a problem after a week. The second time we experienced the same issue was on 5/19/2026 at 21,493 miles. Again, we had it towed to the Chrysler dealer. They told us the same thing and even implied it was the way we were driving that was the issue. The third time we experienced this problem was on 5/30/2026 with 22,636 miles on the odometer. We will be towing it back to a Chrysler dealer.
High voltage battery pack, Power Inverter Module (PIM), and HV charging system. PIM replaced twice (p/n 68381781AD, 8/4/25 and 8/18/25) after being found melted with arcing damage at HV connections. Battery pack has active BPCM fault codes and a recorded cell voltage excursion. Vehicle available for inspection. Vehicle lost all motive power without warning at highway speed on multiple occasions, requiring the driver to pull over. This occurred on a platform subject to recall 24V-536 (HV battery fire risk).

melted inverter and arcing at HV connections were found on a vehicle still being driven daily. BPCM data shows Cell 79 recorded a voltage excursion to 1,526 mV - less than half minimum safe operating voltage - stored in permanent memory. Yes. Lawless Inc. (Woburn, MA), authorized Chrysler dealer, confirmed fault codes PA121-00 and P0A43-00 on 8/4/25 and replaced the PIM. Vehicle returned 8/18/25 with same failure - dealer confirmed arcing damage and melted inverter. Three visits total; defect unresolved after two repair attempts on the same component. All three visits performed by authorized Chrysler dealer under 10-year/100,000-mile HV battery warranty. Stellantis warranty claim opened each visit. No police or insurance involvement. Red warning "Will Lose All Power" appeared on instrument cluster before each shutdown. Battery range has displayed erratically since 2/28/25 (~17,788 miles), when nonlinear discharge was first reported and dismissed. Active BPCM Level 2 safety fault (L2/L1 CELL MAX V CMP_FLT) remains present today.
Vehicle randomly shuts off in EV or ICE mode usually when driving on highway at 60-70 mph; warning comes of "vehicle will shut off soon" check engine light and limp mode; eventually power goes off and steering also stiffens ; this happed multiple times, but the check engine like didn't stay on long enough for the dealership to be able to read it! So I was give the vehicle back then the same thing happed over again! Very unsafe to drive, not feeling comfortable to drive!
Lost power. System said to pull over immediately. Error code P0A43.
My van has been in the shop for 22 days. They have replaced the engine 1 time and I had the van back 2 more times for check engine light issues and now the engine is being replaced for a a second time, so this is the 3rd engine in my 2025 Chrysler Pacifica that has 9100 miles on it.
At 9,000 miles the check engine light came on. We took the van to the dealership and there was metal in the engine and the engine needs to be replaced.
