2021 Chrysler Pacifica acceleration problems

Filed Sep 30, 2026 · Acceleration, Electrical · GA

Around 08/2026, FCA US LLC Dealer performed FCA Safety Recall 52D (the federal safety agency 26V‑362) on my 2021 Chrysler Pacifica Plug-In Hybrid. The recall included a software update to the high-voltage Battery Pack Control Module (BPCM). Before the service, the radio and infotainment system worked normally. Right after the recall service, the radio screen on the instrument panel stopped working and the infotainment software began crashing repeatedly. As a result, the radio and audio system can't be used. The dealer confirmed that the problem appeared after the recall repair but has refused to fix it. The vehicle is still unrepaired. 1. What component or system failed or malfunctioned, and is it available for inspection upon request? The radio and infotainment system failed: the center screen on the instrument panel, its operating software, and the audio system. The screen stays blank or unresponsive, and the software crashes or restarts repeatedly. The failure started right after the Recall 52D software update. The vehicle hasn't been repaired and can be inspected at any time on request. 2. How was your safety or the safety of others put at risk? Because the screen doesn't work, I've lost functions I rely on while driving: Radio and audio, including emergency and traffic broadcasts; The screen also crashes and restarts while I'm driving, which is distracting. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? Yes. Dealer saw the problem and confirmed it appeared after the Recall 52D repair. The dealer has refused to repair it. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? The dealer inspected it after the service recall. 5. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.

While driving at normal road speed, the vehicle suddenly lost propulsion and entered limp mode. A turtle warning icon appeared along with multiple system fault messages. The vehicle began slowing down on it's own and was unable to accelerate. I pulled to the side of the road. The vehicle displayed an error "Stop Safely Vehicle Will Shut Off Soon". After sitting for a period of time, the vehicle restarted and was able to be driven again, but the failure occurred without warning and created a dangerous situation in traffic. Diagnostic trouble codes were present related to the hybrid system and high-voltage battery, including P1D43, P1A21, U029A, and U0412. These codes indicate faults in the hybrid control system and battery communication. A Chrysler service department inspected the vehicle, confirmed the trouble codes, and returned it to me without repair because the issue was not immediately reproducible at the dealership. The vehicle has a history of similar intermittent issues, including prior loss-of-power events and repeated service visits for hybrid system faults. The condition is not consistently reproducible, but when it occurs it results in a sudden loss of motive power while driving. This creates a significant safety risk due to unexpected loss of propulsion in active traffic.

This is a follow up to an earlier submission (the federal safety agency Tracking Number 11591550). After the initial incident, the dealership replaced the hybrid battery on the vehicle. A month later, yesterday, while driving the vehicle on the interstate, I again received the dreaded, "Stop Safely, Vehicle Will Shut Off Soon" warning indicator and the car lost all power about 30 seconds later. Thankfully, I was on an offramp and was able to stop safely. Had I been traveling at full speed in the carpool lane, it could have been very dangerous. The van is now at the dealership for repair, and I hope they fix it for real this time. This is an extremely dangerous situation, with vehicles dying while going full speed.

After having the car serviced to fix the recall, my car stopped running while on the freeway at 60mph. This is now the 3rd time in less than 10 days that this has happened. I had the transmission replaced previously to fix this issue but it has returned.

While driving at full speed on an interstate, I received the message, "Stop Safely, Vehicle Will Shut Off Soon." The van then lost power, and I was able to pull over safely (thankfully!). After about 15 minutes, the van restarted, and I made it about 10 miles until it happened again. After two more shut-downs, I was able to get the van to a dealership, where it has been sitting undiagnosed for over a week now.

Second incident of loss of motive power at 37352 miles on the odometer. Vehicle was traveling on freeway and suddenly displayed message, "Stop Safely Vehicle Will Shut Off Soon." Accelerator pedal had no effect and vehicle began coasting. It was dangerous to coast across multiple lanes of freeway to reach an off-ramp with shoulder wide enough to stop the vehicle. We also had to make it over an incline while coasting and it may not have been possible to reach the shoulder or off-ramp. Prior to this incidence, the vehicle had been brought to a Chrysler dealership due to a previous occurrence at 36997 miles on the odometer. It was inspected by the Chrysler dealership and deemed to be operating normally.

As I was leaving my son's school parking lot - moments away from an on-ramp to a major freeway - an error message flashed on the dash saying "Service Charging System" followed by a message about the vehicle's speed being limited and a red turtle icon. The van instantly was driving strangely. Since I was in a parking lot, I turned everything off and waited for the van to shut down completely. I restarted the van and the warning messages were gone, but the check engine light remained. The van showed more than 15 miles of battery mileage remaining. The week prior, we had taken it into the dealership for the open recalls to be repaired, so we took it back for this issue. The dealership just messaged me saying the van is ready to be picked up and that the charging system was just low. But it still had nearly 1/2 the battery left when this happened! The dealership went on to say, "So here is the deal, we could not verify the concern at this time. There are no codes in the system, nothing to really test for. I can have someone drive it and see if anything happens, but without being able to duplicate your concern, we cannot diagnose it." My sister-in-law had the exact same issue on her own Chrysler pacific Hybrid just a few months ago, while she was on the freeway and her speed was instantly throttled. They replaced the entire electrical hybrid transmission. This is a known issue with this vehicle and it is going to put my life and my kid's life at risk since the dealership cannot reproduce the error. I even sent a picture of the error message, and they say there's nothing they can do.

There have been several incidents that have to do with the electrical components site, such as the adaptive cruise control not working the lanes assist going off, stating that my hands are on the wheel. When my hands are on the wheel, there have been problems when I go to put it in drive. It'll switch back to park and throw on my parking brake. It has also the auto breaking lights have. Come on, my checken and light has come on. It taking in to the dealership and they found corrosion on some of the wires, replaced them. They also replaced the adaptive adaptive control module. It was supposed to magically fix all my electrical problems. Yet I'm still having electrical problems also my navigation on. A scream down by the cluster cluster. Stays on and doesn't go anywhere. I also have video and pictures and things like that of the situations that have gone on with my Van 4 months and nothing has been fixed. I've been told by the dealer and buy a representative from Chrysler. That's my Van is fine. There's nothing wrong with that. But clearly there isn't an electrical issue and. And I pretty God. Nothing happens to me or my family or someone else because of it. Also, the radio, when you shut your car off and open the doors to exit your vehicle, the radio is still left playing and should not also the auto break in just comes on. For no reason. It happened on the interstwhen we were merging in the traffic. And there's no reason it should be doing some of the things that it's doing.

Vehicle was traveling at approximately 50 miles per hour with no indication of an issue or prior warning. Vehicle suddenly lost power, rolled to a stop, engaged parking brake and displayed "Service Charging System" error. Vehicle was non-operable in the middle of traffic with small children inside the vehicle, presenting significant risk of accident and injury. Vehicle was towed to a dealership and remains inoperable, as confirmed by dealer. Dealer diagnosed need for replacement transmission. Vehicle previously had transmission-related recall, which was serviced. No open recalls are in effect, though public searches and owners' groups identify consistent, recurring fact patterns. Chrysler's Star parts department blocked the dealer's part order and neither Chrysler nor dealer have identified the reason. Vehicle remains inoperable at the dealer with no timeline for part availability or repair, and uncertainty as to whether issue will recur.

On Wed, April 5th, 2023 at approximately 10:15 pm I was returning home from a class in my 2021 Chrysler Pacifica Hybrid. I was on local roads and had just transitioned from EV mode to gas mode (having used up all of my battery after about 30 miles of driving) when the car flashed the attached warning sign and I had very little power provided by my accelerator. Note that something similar to this has happened 5x before. All of these incidents had been at highway speeds (70+ mph) with one at about 40 mph. All had complete shutdown of power in the accelerator. In the current case I was able to still have a bit of power left and pulled over to the side of the road. Fortunately, it was late and there weren't too many other cars out so I didn't have as many safety concerns as I had in the past when I stalled on the highway. After I pulled the car over I stopped the car, turned the car off via the ignition button, unbuckled my seat belt and opened my door. Then I restarted my car and the error message attached had disappeared and I was able to return home. Note that I had had the dealer apply Recall 03A a week earlier and this seemed to be what was supposed to happen under that Recall which is NOT identified as a complete fix. Still, it is very disconcerting to lose full power. In my case, I was thankful to not have gotten into an accident.
