2023 CHRYSLER PACIFICA Engine Problems

While driving at approximately 65 mph on I-35 in moderate traffic, the vehicle experienced a sudden and complete loss of motive power. I was positioned in the far-left passing lane at the time of the incident. A notification message appeared on the dashboard screen (likely the "Stop Safely" or "Service Hybrid System" warning); however, there was no accompanying audible warning tone to alert me to the severity of the issue before power was lost. The failure rendered the vehicle unable to accelerate, creating a severe safety hazard. I was forced to navigate from the far-left lane across multiple lanes of traffic to reach the exit while the vehicle was effectively crippled, moving at speeds under 10 mph amidst highway-speed traffic. I was eventually able to exit the freeway at this reduced speed. This was the second time this issue had occurred. The previous check engine light had cleared on its own and I assumed the vehicle was safe to drive.

While driving at approximately 65 mph on I-35 in moderate traffic, the vehicle experienced a sudden and complete loss of motive power. I was positioned in the far-right lane at the time of the incident. A notification message appeared on the dashboard screen (likely the "Stop Safely" or "Service Hybrid System" warning); however, there was no accompanying audible warning tone to alert me to the severity of the issue before power was lost. The failure rendered the vehicle unable to accelerate, creating a severe safety hazard. I was forced to navigate to the shoulder and stop for the vehicle to reset and allow me to reach the exit while the vehicle was effectively crippled, moving at speeds under 10 mph amidst highway-speed traffic. I was eventually able to exit the freeway at this reduced speed. This was the third and fourth time issue had occurred. This happened IMMEDIATELY after leaving the dealership to resolve this exact issue and was told that the vehicle was safe to drive again.

As I began driving errors popped up engine failure, electrical system and hybrid system errors, the gas pedal would not move beyond 10 miles per hour, the brakes made a weird noise as if were trying to start the car. This happened with no warning.

The vehicle experienced multiple incidents of sudden power loss while driving.

On August 2, while traveling about 75 MPH, the check engine light came on along with the warning "Stop Safely – Vehicle Will Shut Off Soon". The vehicle started immediately losing power. We were driving in the fast lane in traffic so pulling over was difficult and dangerous. After we were to the side of the road, we turned the van off. After 10 minutes or so, we continued on and pulled over at a rest stop. We have an OBD2 and checked the codes. At first, there were no codes even though the check engine light was on. After checking a few times, there were 2 codes. They were P1C65 PD and P0A43. I took the van into the dealership on August 4. They saw one of the codes saved. On August 7 the dealership preformed a software update. They were not able to reproduce the issue. Today, September 19, while driving, the check engine light came on with the warning "Stop Safely – Vehicle Will Shut Off Soon". The vehicle again started immediately losing power. This time it happened when traveling about 45 MPH.

While driving in the carpool lane on the freeway, the vehicle displayed “Stop Safely. Vehicle Will Shut Off Soon” and lost all power. I am pregnant and had four children (ages [XXX] , [XXX] , [XXX] , and [XXX] ) in the vehicle. The outside temperature was over 100°F, and we were two hours from home. The car was completely disabled in heavy traffic, creating an extreme safety risk for my family. After waiting about 15–20 minutes, the vehicle restarted and we were able to continue. A code scan showed P0A78 – Drive Motor “A” Inverter Performance. This is a serious safety concern, and I am requesting immediate inspection and repair under warranty.

On 8/12/2025, he vehicle displayed a warning that said "Stop Safely, Vehicle will shut off soon" shortly after it was parked. It also displayed a red turtle and the check engine light. There was no warning or check engine light prior to the message that the vehicle was going to shut off. Fortunately, we had already parked safely, but were on the freeway traveling and about an hour away from home. It was 100 degrees outside, and we were stranded with no help from Chrysler customer care other than to tow the vehicle, leaving our kids and dog in a parking lot with no car. We declined this option and had it checked by a diagnostic computer at Jiffy Lube, which returned no diagnostic code. Eventually, all of the warnings and check engine lights went off, and we were able to take it home. We took it to the dealership at the earliest opportunity on 08/14, and they confirmed that this is a known issue and would require a transmission replacement. There is no timeline on the repair or replacement, only that it will take "a while". They do not advise that we take the van back because the issue could come nback at any moment and the vehicle could shut off without warning.

While traveling on an interstate highway at highway speed (65-70 mph), a red turtle warning light came on with the message "Pull over Safely; vehicle will shut off soon." Almost immediately, we lost all power and glided into the right-hand shoulder. We narrowly missed being rear-ended. We got it to a local dealer, where the service department informed us we need a new transmission. The car has less than 13,000 miles on it.

Driving on the highway, all of a sudden, my car dashboard shows a message that " Vehicle will shut off soon" and the accelerator does not work. It was horrifying; there is no median to pull the vehicle out.

My vehicle suddenly experienced a loss of power while driving, starting at 62000 miles per hour. Sometimes the same problem occurs again after driving for several hundred miles per hour, and sometimes even after driving for tens of miles per hour. When this problem occurs, the vehicle cannot continue to drive and can only rely on inertia to slide. It must be parked on the side of the road, the engine must be turned off for one minute, and the vehicle can start again to drive normally. My car has now driven at 89000 miles per hour, and this problem has occurred countless times. At first, it occurred about once every 2-3 days, but now it occurs twice a day.

[XXX] First “Red Turtle” Breakdown on Freeway After about an hour of freeway driving, car went into “red turtle mode” (“limp mode”) on the freeway, alerting us that the engine would shut down shortly and that we needed to get to a safe place to stop. The car wouldn’t accelerate fully, putting us in danger on the freeway, where cars were speeding all around us. June 2025: Dealership’s First Attempt to Fix The dealership showed stored error codes P0A43 Drive Mode Code A Position Sensor Intermittent. But, the tech said they were unable to replicate the error. They kept it in the shop for a couple days, then sent the car home with us with no fix. They told us to restart the car a few times and it should go away. [XXX]: Second Breakdown on Freeway On [XXX], with all three kids in the car, we drove the car from Sacramento to San Rafael. On the way there–the first long car trip with the van since the [XXX] incident, the Red Turtle Alert appeared again. We were going uphill and unable to fully accelerate on the freeway, again putting our entire family in danger. We were luckily able to pull off of the freeway, restart the car several times, and continue driving–wondering the entire time whether the vehicle would again lose power, and sure enough it did. [XXX]: Third breakdown on freeway Later that same day, on our way home, the Red Turtle alert appeared again, the vehicle was unable to fully accelerate, and the message warned us that the car was about to shut itself down. This time, we were on the freeway with no exit available to us. We had to pull over onto an unprotected shoulder, with cars speeding by us on both sides. It would have been unsafe for any of us–but especially my toddlers–to exit the vehicle. We sat on the side of the freeway, restarting the car repeatedly, waiting to see if the Alert would clear and the vehicle would become drivable again. Eventually, it did. We brought the car to the dealership again. Spent over a week there INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA)

On [XXX] while traveling on the interstate the car issued a warning engine light and turtle image to pull off the road as the car would shut off, immediately it had no power, maybe could only go 30 mph. Took the car in on 5/10 which was the earliest appt. Said they did a software update, gave the car back. Took the car again on [XXX] when the same warning appeared again on the interstate, same situation disabled vehicle at high speeds on the interstate and no power. Said they changed a module related to the error and gave me the car back. Yesterday as I was driving on [XXX] 70 mph the car gave the same warning and shut off again, immediately I had no power, 30 mph. The dealer acknowledged my car is not the only one in his shop with this issue. They had my vehicle for nearly a month the time before. This vehicle is not safe to drive on the highways as it can shut off at any time. It's a known problem by Chrysler and their idea of fixing it, is issuing a warning which gives you almost no time to get off the highway before your speed is greatly reduced and even then you're stuck on the side of the highway with cars speeding by in an area with no shoulder or construction zone you'd be stuck in the middle of the road. Someone will wind up dead on the highway, I am lucky that in the 3 times this has happened I have not been hit and have been able to safely get to the shoulder, but I don't see Chrysler being able to fix this issue, the dealership did reach out to the manufacturer each time. I know my car is not the only one that has this issue and I'm concerned for the safety of anyone who owns one of these. A simple google search of this vehicle will show the problem is wide spread.

The van did not transition from electric to gas engine when driving and battery for the electrical engine was depleted. The dash board displayed a red turtle and said slow on dashboard. But it would not drive forward. I was on a hill and the van backed down the hill in reverse. I did this multiple times - turn off van, restart van and try to go up hill, reverse it down hill again. At some point, there was enough electricity for the electrical engine to kick in and I was able to drive home. After the van set for a while, it restarted and I was able to drive it to my ultimate destination 147 miles away. I researched online and found there is a recall for this very thing, but it does not include my car. Why is my life so hard? Its a new van to me.

I have pulled out to go across road and it was like the car wouldn't go. It would be like it was coasting. And then it would kick in hardand fast. Very very dangerous. Have you had any other people say that.? It's done it about 5 times.. where I almost got hit and or ran off road when it did go.

Vehicle displayed "stop safely, vehicle will shut off soon" followed by a complete lack of power. We managed to get to the side of the highway safely. Vehicle would not turn back on until about 45 minutes later. Before we turned off the vehicle it said service charge port. Check engine light is on, even after we managed to get it started. Currently at the shop, waiting for information on why.

Driving at highway speed (70 mph) the vehicle repeatedly has flashed a warning : Stop Safely Vehicle Will Shut Off Soon The engine cuts power and the vehicle must be pulled over and turned off and cannot keep driving. It leads to very unsafe conditions at highway speed. The vehicle was repaired once for the defect by Chrysler but it still continues to occur and is now being repaired again.

While exiting an interstate, the van felt like it had popped out of gear and lost power, and the instrument cluster had the message "Stop safely, vehicle will shut off soon." I was in the middle of three lanes on the ramp, and due to traffic and no shoulder I was unable to stop off the side of the road. The van died at the top of the ramp at the traffic light, causing a risk of being rear-ended by approaching traffic. I had my two children in the van at the time. After attempting to cycle the ignition several times and stepping out to wave traffic around as the traffic light cycled several times (causing a traffic backup), the van started and drove normally albeit with the Check Engine Light on. I have not had the time to take the van to a dealership for diagnoses, but looking online this is not an unknown problem and is related to the Pacifica Hybrid's transmission. Just wanting to make NHTSA aware of another event of this fault occurring.

I rented this car from Budget on Saturday, May 31, 2025. When I drove it on Sunday, June 1, 2025. The check engine light came on and the car gave a warning that it would shut off. The first time I saw this notification I was stopped at a stopped sign at a 4 way intersection. The car proceeded to shut off after some time (maybe 20 seconds or so, not sure). I was at a full stop and the car was in "Drive". When the car shut off it went into "Park" automatically. I turned the car back on and put it back in "Drive". The car would not move. I check to make sure the parking brake was not turned on and it was not. I put the car in "Park" and back into "Drive" and the car still did not move. I turned the car off a few more times before it switched back into gear normally. I was unable to return the car at that time. About an hour later as I was driving on the interstate in the left lane, the same warning light came on. I had to immediately move from the left lane of a 6 lane interstate all the way to the right shoulder. There was no exit or left shoulder. Once I got there the car idled for a moment and shut off; I am uncertain how long it was before it shut off. I waited a couple of minutes since I was also shaken up at having to move so many lanes on a busy interstate with so many lanes. I got to my destination after about 30 minutes. On the way home about an hour in to the drive, the same thing occurred. I moved onto to the right shoulder of a two lane interstate at this time. This time I shut the car off myself and waited a couple of minutes to turn the car back on. I then drove another 45 minutes home. Then this morning, same warning in my driveway before I left to return it. There were issues with the blind spot warning not working some of the time as well as the display screen would flicker on and off or just become disabled but still visible. I have reported this to the rental company but I want that car off the road.

I received a warning to park safely, engine will shut down soon. This is the third time it has happened. One time coming down a mountain with no place to pull over safely with a van full of family members. Second time at high speed on an interstate, this time on a high speed local road, but had enough time to pull over before losing power. The van has been in the shop and/or waiting for repairs for over 10 weeks during my 53 weeks of ownership. Chrysler has delayed accepting the recommended repairs that their dealer states is necessary. I have spoken to other Pacifica owners that has experienced the same issue. Is Chrysler waiting for folks to get killed before accepting responsibility?

We were driving on the freeway, 80 MPH, 0% battery life. Warning came on the dashboard stating something like “ Pull over safely, engine will stop”. Engine had already stopped and we luckily avoided impending doom and pulled off to the side of the highway. Turned car off, waited a couple min, and started the car again. Car turned on with check engine light. Able to slowly get to the next exit. Next morning, took to dealer. Say there were not able to see any issues. Van is around 28,000 miles.

Numerous times over the last eighteen months, our 2023 Chrysler Pacifica PHEV enters 'Turtle Mode' where a red turtle illuminates on the dashboard, and the car loses all motive power. Sometimes this occurs on local streets, but most recently it occurred during interstate driving, requiring evasive maneuvers to exit the driving lanes and get to the shoulder before all forward momentum stopped. So far, turning off the vehicle, opening the driver's side door and re-starting the engine clears the problem temporarily, but yesterday - [XXX] - the vehicle entered 'Turtle Mode' eight times during the four-hour car-ride from northern West Virginia to Northern Virginia. Several visits to Chrysler dealerships have resulted in zero fixes as they have been unable to replicate the conditions.

We rented a '23 Pacifica from Enterprise. While driving 70mph on an interstate in Houston, a safety warning popped up "Stop Safely Vehicle Will Shut Off Soon". On the interstate, I wasn't able to keep my speed. Speed dropped quickly and dramatically. Luckily, I was able to get to the side but could have been hit in the process. My 2 daughters were in the car. It was terrifying. According to my research Pacifica did a recall of 67K Hybrids and their solution?? Add software that gives a warning. That was the solution. NOT TO FIX THE DEADLY ISSUE but to add a warning. [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle randomly went into limp mode. The check engine light came on with error code P0A3F. The vehicle was restarted and drove normally with the check engine light (CEL) still on. We immediately made an appointment with the dealership to get it looked at. As we were driving into the dealership parking lot the CEL cleared itself. There is an existing TSB for this exact scenario and symptoms. The dealership and Chrysler corporate (Stellantis) are refusing to fix this issue because there isn’t an “active code.” The code is in the history. Since then the CEL has come on multiple times but cleared itself too quickly to get it to the dealer in time. We took it a second dealership this time with an active code, but the code cleared itself upon restarting the car after leaving it there. This vehicle is not safe to drive since it randomly goes into limp mode with no power. This poses a very dangerous and unsafe situation that can endanger me, my family, and other drivers around me.

While driving at highway speed the vehicle flashed a vehicle and I’ll shut down sign. A red turtle flashed and the vehicle began to decelerate. Had to pull over to a less than safe sand shoulder. Had highway speed traffic directly behind me. Dealership pulled codes related to the transmission. No previous issues or sign thereof. 25k miles.

On our daily commute the car came to a stop at a light and then the car then turned off and would not start again. We tried everything but the engine would turnover. After 3 hours, the car then started and we drove it to dealership and they detected no faults or codes.

This is the second time this happened in one week. Incident happened immediately after being sent home without repair by the dealership. Driving down the interstate, our car displayed the "Stop Safely. Vehicle will shut off soon." Red turtle light came on, and car lost all acceleration. We managed to pull over without being hit. Turned the car off and then back on. Check engine light was now on, but the car would drive. Hybrid battery was charged at 66%. In both shutdown instances, dealership says it is unable to replicate the problem, and therefore will not look further into the problem.

We were driving on the interstate at approximately 70 mph when our car gave the warning, "Stop Soon. Vehicle will shut off." A turtle warning light also lit up. We pulled over to the side of the road and turned the car off. After a few minutes, we were able to turn the car back on and drive home, though the check engine light was then on. We took it to the dealer the next day, with the check engine light still on, and the dealer was unable to reproduce or diagnose the problem. They said there were so many warning codes that they could not determine what was the problem and that if they followed what the codes were telling them, they'd have to replace the entire wiring system of the car. They also said that one or more of the codes was related to the transmission. They drove the car extensively and couldn't reproduce the shutdown. They are currently still trying to diagnose the problem with the car at the dealership. There were no warning signs from the vehicle prior to the incident. The incident occurred right around the time when we would have depleted the all-electric charge and switched over to using gas.

We have less than 3K miles currently on this vehicle. We were traveiling to the mountains for a vacation when the check engine light illuminated. Stayed on for 2 days and reset itself. We were in the Smokey Mountains and a warning came up to "Stop Safely Vehicle will shut off soon. Within a few minutes, all power was lost, all lights were inoperational including the 4 way hazards. After just a few minutes, the van restarted and operated as if nothing happened. The check engine light stayed on long enough for a Chrysler dealer to read the codes. Esentially, a problem with the High Voltage System Interlock Circuit A, Drive Motor A Inverter Performance are the major codes. A slew of others all related to this issue. The hybrid mechanic stated it is the same issues that plague the 2017-2021 Pacificas hybrids. Losing all power is not acceptable, especially in the mountains with a vehicle less than 4 months since delivery.

While driving with my young family my vehicles engine shut off and all steering was lost going appx. 50mph. As the the vehicle shut off, a warning popped up and said “stop safely, vehicle will shut off soon.” This was very dangerous and could have caused a life treating injury.

On the afternoon of May 26, 2024, I received a warning "Stop Safely - Vehicle Will Shut Off Soon". I pulled to the side of the road but was still in an active traffic lane in a traffic circle and cars had to stop and/or swerve to avoid hitting my car. If this had been at night my safety would have been even more greatly compromised. The engine promptly shut off and would not restart. I was towed to the nearest dealer which still has not diagnosed or repaired the car. This may be related to recall 23V-010 and the ongoing RQ24004, of which the dealer had no knowledge. I took delivery of the car, a 2023 Pacifica plug in hybrid, on March 25th and it has less than 4000 miles on it.

Lost engine power on highway with warning on the dash "Stop Safely, Vehicle Will Shut Off Soon"

I was driving in Virginia in a rental and the check engine light came on then the following message came on "get to a safe place the car is going to stop". A few seconds later the vehicle shut off and stop in the middle of traffic. I did not have time to pull over. I turned everything off and restarted the vehicle it was fine for about a mile then it happened again. I waited about 10 minutes before starting the vehicle to take it back to the rental company.

Vehicle has an auto start/stop feature which turns off the engine when the brake is applied and the vehicle is at a full stop. When stopped at a traffic light with the engine auto stopped, driver lets foot off brake when light turns green, but engine fails to start. Vehicle remains stopped in an active traffic lane, or potentially in the middle of an intersection. A chime and a display message guides driver to shift to park and manually restart the car. Has happened at least five times in 6,900 miles we have owned the vehicle. Dealer service department could not reproduce or find any log of the event occurring. They told me it needs to happen more frequently so they can reproduce it. I find other reports of this problem online going back to at least 2018.

The contact rented a 2023 Chrysler Pacifica Hybrid. The contact stated while driving downhill at approximately 20 MPH, the check engine warning light illuminated, and the message "Brake Release" was displayed. The contact stated that the braking system malfunctioned, and the vehicle failed to stop while depressing the brake pedal before the vehicle stalled. The vehicle was pulled over to the side of the road and restarted. The vehicle was drivable, but the check engine warning light remained illuminated. The contact stated that the check engine warning light then turned off. The cause of the failure was not yet determined. The rental company was notified of the failure. The manufacturer was not contacted. The failure mileage was 300.

Mileage: 300

The contact owns a 2023 Chrysler Pacifica Hybrid. The contact stated that immediately after purchasing the vehicle, while driving approximately 5 MPH, the vehicle stalled. The following day, the vehicle was taken back to the dealer who was unable to identify the cause of the failure and no corrective service was performed. The contact stated that after retrieving the vehicle, while driving from the dealer the failure reoccurred and the vehicle stalled. The vehicle could not be restarted and was towed back the dealer. The cause of the failure was not yet determined. The manufacturer was not yet contacted. The failure mileage was 35.

I have a 2023 Pacifica with around 3k miles. I purchased brand new. In the few months that I have owned the vehicle, it has turned off about 5 times while driving. It loses all power. Engine, power, etc completely dies. I need to restart the vehicle, wait for start-up, and then I can continue driving. The vehicle has currently been at Arrigo Sawgrass Chrysler since 07/13/2023. Arrigo continues to say "They can not duplicate the issue and it does not show on computers " I called Chrysler Corporate for escalation. They told me that they have no record of the vehicle being in a repair shop until 07/25/2023. The bottom line is, this is a real problem. I have a 4-year-old, 2-year-old, and 2-month-old plus myself and my wife in the vehicle. What if this repeats and the car turns off in an intersection with a semi coming or worse? I understand the computer is not always accurate and it's a new vehicle. I do not feel safe if they return the vehicle without correcting the issue and do not want my family to be the test dummies for an issue that can be prevented. Chrysler is impossible to intervene and the dealership is only doing what they can. However, they don't get paid if they cant find issues so it's a tough situation.Thank you in advance.

While driving I got "rear seat alert" followed by "Car Shutting down in 9 secs" message, it happened twice. The first time on Northern State Highway in NY. I was driving with my family, and the car unexpectedly shutdown happened. Nothing worked, I had no power, no steering, no brakes, all gone. Our luck was that I was already on the right lane and just had to let the car stop in the curbside. Because of the messages, we thought the rear door was opened or something. After a few minutes, after several tries, the engine started, and we exit the highway and parked on the local road to try to understand what happened. We decided to continue our trip on the service road. We end up on Ocenside, NY on a two lane, busy street and it happened again, but at this time I was not able to move the car to the curb, the car stop completely on the middle of the road, no steering, nothing. Because of the incoming traffic, our hazard lights alone were not enough to warn the coming traffic. We though that an accident was eminent, for which we called 911 for help. I could not get out of the car because of the speed of the incoming cars. After several attempts, the car turned on again, I parked on the curb and I called the AVIS Rental Roadside Assistance, because I was not going to put my family, including an 87 year old in jeopardy. After we got home from the long, stressful day. I searched internet and for my surprise, there were several posts (links) relating the same issue I had. Including recalls from Chrysler about a short circuit, which could even cause a fire. Chrysler issued a NO PARKING INSIDE note, which is hard to understand. I feel it is my obligation, as a family person, to report this incident, because this car should not be in the ROAD. Avis is currently RENTING this car. Furthermore, for my surprise, I saw a ad on NBC, 5pm yesterday, 07/26/2023. It is just a matter of searching on internet to see the DANGER that families are exposed.

1. Engine Light and the "A" warning light stay on while driving. 2. It's unsafe with family in the car; fear it will shut off on the highway. 3. yes, the dealer has agreed its a defeated part causing the engine to light to come on 4. No warning lights before driving a car for a week.
