2023 Chrysler Pacifica engine problems

“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…”

“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.”

“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…”

“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). A 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.…”

“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!”
