2021 Chrysler Pacifica: complete transmission failure

Filed Jul 28, 2026 · Electrical, Fuel system · PA

This 2021 Chrysler Pacifica Hybrid has a severe and recurring history of catastrophic high-voltage hybrid powertrain and transmission failures that cause a sudden loss of motive power while driving, presenting an immediate safety hazard. The vehicle has already required two full automatic transmission (eFlite EVT) replacements under factory warranty due to internal failures. It has experienced multiple high-voltage component repairs, including software modules for the power inverter. The vehicle is currently experiencing a recurring failure and is displaying active diagnostic trouble code P0A78 (Drive Motor "A" Inverter Performance), indicating a critical fault in the high-voltage hybrid propulsion system. Prior to the current failure, the check engine light illuminated, and the vehicle experienced propulsion system degradation. This failure mode risks a sudden shutdown of the hybrid drive system at highway speeds, creating a severe risk of rear-end collisions or being stranded in active traffic. The recurring nature of these transmission and inverter failures indicates a systemic safety defect in the hybrid propulsion system. The issue and the active P0A78 code have been pulled, reproduced, and confirmed by an authorized dealership (Diehl Automotive of Robinson), where the vehicle is currently held and available for inspection. The manufacturer has been notified via an open corporate case (#97399722).

While driving the vehicle, the accelerator will become inactive and result in the vehicle slowing to a stop. I will shut off the ignition and let vehicle rest for 10-20 mins before restarting. This does not resolve the issue and I end up towing the vehicle into the manufacturer’s service department. This often results in 100s of dollars in “diagnostic” fees. The service dept claims it’s bad battery, changes and issue arises again. Next they say it needed a software update, and a few days later it fails again. Next they said it was PCM module and replaced it, and finally they replaced the transmission. The 4th visit, change of transmission, lasted a little over a year and then the issue arose once again! After paying $259 in diagnostic fees, they said I used a bad “charger”

This vehicle quit driving and you can move it. Confirmed bad transmission. I bought it this way from the insurance company because it bounced off a concrete barrier. I suspect this happened when the transmission failed. Unsure of a police report due to it happening to the previous owner.

Incident: While driving at highway speeds (65–75 mph), the vehicle issues imminent-shutdown warnings, the reduced-power (‘turtle’) light and check engine light illuminate, and the vehicle loses motive power. The driver must pull over to the freeway shoulder immediately and restart the vehicle. The condition is intermittent, occurs after cold starts, and sometimes with cruise control engaged. Safety Risk: Sudden loss of motive power at 65–75 mph without warning creates extreme crash risk. This is the exact risk stated in the recall notice. The software-only remedy appears insufficient. FCA’s own Warranty Extension Campaign XE1 — covering transmission replacement at unlimited years/unlimited mileage — suggests FCA is aware the software fix may not be adequate. Requested Action: Please investigate whether the recall remedy is adequate or whether physical transmission replacement is required. This vehicle has been documented experiencing the recalled defect seven times after the recall repair was completed.

While driving down the highway at 70 miles per hour ater driving 2.5 hours our 2021 Pacifica hybrid minivan flashed a warning on the vehicles display saying approximately "Warning Engine Shutting Down". The engine immediately shut down in the middle of the highway and we were forced to coast off the highway to the shoulder. The engine warning light came on. We turned the car off for a few minutes and proceeded to start the engine. The engine warning light was still on, but the other message was gone. We attempted to drive towards our destination and approximately 30 minutes later the same thing happened again. We tried one more time since we were several hours from home and within 30 minutes the vehicle had the same issue. At that point we decided to try to get home. We drove the vehicle 15-20 mins at a time and then exited the highway over and over giving the vehicle time turned off. After returning home with no additional events the engine warning light went off the next warning. This was on a Sunday so we were unable to get it to a dealer. The next day we dropped off the vehicle at Nappletom Chrysler dealership. The called us the next day and told us they could not cause the event to happen again. They could see a set of error codes showing the problem occurred, but told us there was nothing they could do and it was up to us to cause the problem and then return the vehicle. Now I have a minivan with 70k miles on it that my wife primarily uses my with to get my daughter from place to place and I have no idea when this vehicle will shut the engine down at any time potentially causing a dangerous accident. I believe Chrysler has the responsibility to determine what the issue is. Researching on the internet show this is a common problem for my vehicle and typically requires a new transmission or and engine wiring short.

When driving our van from Nashville to Memphis, we were 2 hours from home when we received an on screen alert stating “Stop Safely - vehicle will shut off soon”. This was in a construction area with little to no shoulders to pull the vehicle over as power loss began to occur. We contacted Chrysler for help but the nearest dealership told us the earliest they could see the vehicle was 3 weeks from Tuesday. I had 3 children in the car ages [XXX}. A web search for this shows how prevalent this issue is with several blogs and Reddit forums indicating a problem. the federal safety agency even has an open investigation into this specific issue. Apparently the only fix is a full transmission replacement, but we have no assurance from Chrysler that will happen and now our van is left 3 hours away in Memphis as we had no choice but to leave there.

My car has the 03A recall, and had the software update in March 2024. In Summer 2024, I got the red turtle, "Stop, pull over. your car is going to stop" warning, my car stopped moving, etc. I was able to get it restarted and CEL came on and has been on ever since. I took it in for the open recalls (66B), and state inspection, as well as the liftgate recall that was performed by the dealership but the liftgate has never worked since then. They stated that all the recalls except 66B were completed and when I asked why I had gotten the STOP NOW message after the software "fix" was done, they had no answer. I provided them with research stating that Chrysler had issued an unlimited lifetime warranty for these transmissions, since that is where the short is located that is causing the cars to stop. They have insisted since then that the transmission isn't the problem; that my hybrid battery is the problem. I have had no issues that would indicate the battery is the problem, but plenty to indicate the transmission is the problem. My car's been in the shop since March 17, and it is April 27. The new battery was supposed to be in on April 10, but there is still no ETA. I have a STAR case and a case open with Customer Cares, who has been absolutely no help in getting this problem actually fixed. Despite my providing the dealership and Customer Cares the necessary information stating that the new transmission is the only repair that will stop the car from stopping randomly, endangering myself and my family and other people on the roads, they continue to encourage me to "trust the engineers" and let them replace the battery. They are REFUSING to fix the issue, and I will not drive that car until it's properly fixed. This transmission issue is creating death traps and there is a known fix that even Chrysler has acknowledged by issuing lifetime warranties on the transmissions affected by this recall, yet the dealership and Chrysler Cares refuses to perform the fix for it.

5-6 times, our car has gone into "turtle mode", where a warning comes on telling you to pull over ASAP, and that your maximum speed will be limited. We've been in and out of Gwinnett Chrysler in Stone Mountain, GA, and they've never solved the problem. Since then, it has happened twice more and we made it to an Auto Zone type store each time, and they read the error code. Both times, the code was POA43. One said "Power Train System Drive Motor 'A' Position Sensor Circuit Intermittent" and the other said "Primary DTC - MotorReSolver Open/ Short". On forums many people report this issue, and most have gotten new transmissions to resolve it. This started on [XXX] AFTER I had Gwinnett Chrysler fix 4 recalls and do routine maintenance. It has been going on for 7 months at this point. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On [XXX], I was driving the vehicle on a busy highway with a posted speed limit of 70mph. While operating the vehicle at ~70mph, the front display showed a message that the vehicle was going to stop and to pull off safely. Unknown at what point the vehicle will stop, in a panic, I pulled off on the highway and immediately called road assistance for a tow. After calling the dealership, they told me to start the vehicle again, which I did and it showed the check engine light illuminated on the dash. He advised that the vehicle should be able to be driven to the dealership rather than needing a tow, so I cancelled the roadside assistance. On May 12, 2023, the dealership informed me that they did not find anything wrong and said I could pick the vehicle back up since they couldn't replicate the issue. On my drive home, the exact same issue happened and in a panic I pulled off on the same highway with posted speeds of 70mph. The car was at the dealership from May 12 2023 - June 26 2023. The dealership replaced the valve body and transmission. On [XXX], while driving with two young children [XXX] and [XXX] ) on the same highway with posted speeds of 70mph, I received the same dash message. The highway was very busy that day and the concern was escalated with my young children in the vehicle. I was able to pull off. I turned off my vehicle, turned it back on, which put it in limp mode so I could putter to a safer spot than the middle of an off-ramp. I turned it off once more and restarted it, and it allowed me to drive with the check engine light. The next day (XXX), I took it to the dealership and they just confirmed today (7/23/24) it once again needs a new transmission. So I have been put in an extremely unsafe condition 3 times in just over a year with no new resolution beyond just trying to replace the transmission once again.

While driving from Texas to Wisconsin our van powered down twice while at freeway speeds in traffic. We had 6 people in the van and were lucky to safely reach the should each time it happened. Transmission was replaced 2 years ago to correct this issue and it returned. Van was recently at dealership in Texas for inspection and work and found no reason to fix recall issues that are now being stated to have needed to be fixed.

Driving at 65-70mph on the Interstate and vehicle gave message "Stop Safely - Vehicle Will Shut Off Soon". As indicated, shortly after, vehicle lost motive power and we had to coast to the shoulder. As we were going downhill, we managed to make the next exit and pull off. On flat ground, vehicle would only crawl at walking pace. Vehicle did restart after a full off/on cycle and subsequent dealer diagnosis is the hybrid transmission replacement.
