While driving on XXX in [XXX], the van suddenly said "Stop safely, the vehicle will shut off soon". We were in a dangerous spot on a narrow section of the freeway. I was able to turn the van back on and drive for a couple of miles and then it forced me to pull over again. There was a lot of traffic driving by and swerving toward us so I started the car again and made it to an exit, where we were towed to the dealership. The dealership pulled a code P0A43 and noted a rattling sound from the transmission, and a burnt smell/metal contamination in the transmission fluid. The dealership sent the information to the manufacturer for a warranty replacement of the transmission. The manufacturer denied coverage, claiming that the Salvage title voids the warranty. However, this warranty is a result of recall 03A/23V‑010, which should remain to be covered by law, regardless of title status.

On October 7, 2024, my vehicle was serviced at Coastal Chrysler Dodge Jeep Ram for a front-end rubbing/scrubbing noise that increased with speed. The dealer diagnosed both front hub assemblies as failed and replaced both front hub assemblies. I was charged a total of $2184.41 for the repairs, including parts and labor. In less than two years, I again experienced significant front-end noise and safety concerns. On May 19, 2026, because I urgently needed the vehicle and was unable to obtain a timely appointment with the dealership, I took the vehicle to a well-regarded independent repair facility, Koala Automotive Repair LLC. Their findings were extremely concerning. The mechanic documented that: The front wheel bearing was completely worn out. The axle had ripped due to contact with the strut assembly. Bolts on the hub bearing assembly were “very loose” and reportedly “finger loose” The vehicle owner stated that the hubs had recently been replaced by the dealership The independent mechanic further advised that the components replaced in October 2024 should still have been under dealer warranty, and that the second repair involved the same components and directly related failures. I am deeply concerned that: Components replaced by the dealer failed again prematurely; The loose hub bearing assembly bolts may indicate improper installation or insufficient torque procedures during the prior dealer repair; and The subsequent failure created additional damage to the CV axle and related front-end components. This situation caused: Significant unexpected repair expenses: I had to spend a total of $1,932.71 for the second repair. Loss of use of the vehicle. Safety concerns for myself and my passengers.

The hybrid propulsion system on my 2020 Chrysler Pacifica Plug-In Hybrid has repeatedly failed, resulting in sudden and complete loss of power while driving at highway speeds. The vehicle enters full limp mode, displays a red turtle warning light, and the motor cuts out entirely, creating a serious collision risk. The failure occurs without warning and has happened on multiple occasions. The root cause has been traced through escalating component failures: first the Power Inverter Module (PIM) was found to have an internal failure disabling regenerative braking and causing the motor to cut out; subsequently the battery charging module was found to be failing, causing the high-voltage battery to drain to 0% and stall the vehicle. Both components were replaced by an authorized Stellantis dealership under warranty. Despite replacement of the PIM, the charging module, and ultimately the transmission, the defect has not been resolved. The vehicle has been confirmed defective by the authorized dealer on each visit and has been subject to a STAR (engineering escalation) case with Stellantis. Warning symptoms include the red turtle warning light, check engine light, and sudden power loss. The vehicle has been out of service for cumulative warranty repairs exceeding 130 days, including a continuous period exceeding 90 days. The vehicle remains unrepaired and in dealer custody as of the date of this filing. The dealer has confirmed the defect on each visit and has conducted multiple rounds of diagnostic testing and component replacement, none of which have restored safe and reliable operation. The component failures are available for inspection upon request.

This submission supplements my prior the federal safety agency ODI complaint regarding the same vehicle and loss-of-motive-power condition. On Nov 8, 2025, the vehicle experienced a loss of propulsion at highway speed, creating an immediate safety risk. The vehicle could not maintain speed and required evasive action with no propulsion to avoid traffic hazards. Following the incident, the vehicle was inspected and stored diagnostic trouble codes P0A3F-00 and P0A43-00 were retrieved, relating to drive motor position sensor / resolver signal loss or degradation. These fault codes are associated with loss of propulsion and indicate a propulsion control signal-path fault, rather than a condition resolved by software calibration alone. The vehicle remains available for inspection and is out of service at a dealership due to unresolved safety concerns. Since my prior ODI complaint, I provided formal written notice to the manufacturer describing the incident, the retrieved fault codes, and the safety implications, and requested a written response. Receipt was confirmed by USPS certified mail on January 6, 2026. No written response was provided, and repeated attempts to contact the manufacturer through customer service channels were not returned. The manufacturer authorized only a recall firmware update and declined to authorize or perform the intermittent wiring and resolver diagnostics identified in its diagnostic procedures for these fault codes. The firmware update does not inspect, repair, or replace the resolver, wiring, or related hardware indicated by the stored codes, and does not determine whether the underlying propulsion fault has been corrected. As a result, the vehicle has been out of service for more than two months, and the risk of another loss-of-propulsion event remains unresolved. This update documents the manufacturer’s non-response after notice and reliance on a software-only remedy that does not address the indicated propulsion system fault.

Transmission shifts very hard from 2nd to 3rd gear and 4th to 5th gear at random times and at random speeds. Sometimes it occurs in parking lots at less than 15mph and other times at highway speed above 65 mph while cruising. This has caused the engine and transmission mounts to fail prematurely. When it was taken to the dealership multiple times, the service department said they could not replicate the issue but opted to reset the computer anyways. This fixed it for about 2 weeks before the issues came back. A computer reset will wipe the transmission shift learning but with normal daily driving it comes back. This should not be considered "normal" or expected behavior.

I purchased this van in March 2025, it was used about 62000 miles, but dealer said it was in good condition, no issues. In September 2025, a battery light came on, that also activated the Start/Stop could not be used and needed service as well as Service Shifter. I brought the vehicle in and they simply replaced the auxiliary battery and sent me on my way. On November 13th, I was driving and a battery light came on as well as the Stop/Start not available error, and then moments later said "Stop Safely Vehicle will shut off soon". Thankfully I was only moments from home, and made it safely with my 5 children who were also in the van. Obviously this is dangerous as the vehicle stopping while driving can kill myself, my children, anyone in my vehicle, as well as cars around me as I live in a busy area, Tampa, FL. This car had just been given a review in March when put up for sale, and I had brought it in for an oil change, as well as a motor mount replacement, and the aux battery change, before this. My car has been serviced multiple times and this should have been checked or errors/updates reviewed. This auto/stop start seems to be a key in the safety issues as well since that light comes on every time there is an issue. Now the dealer states they are going to replace my PDC, main fuse box, and see if that fixes the error, but I have read that this is an error in many Chrysler Pacificas and mine is another.

Component/System: The propulsion system of my 2020 Chrysler Pacifica Hybrid, specifically a suspected internal transmission wiring-connector short—the exact hardware defect identified in Recall 23V‑010 as capable of causing sudden loss of motive power. In my case, both propulsion sources (gas and electric) simultaneously ceased providing power, leaving the vehicle unable to accelerate. The vehicle, its transmission, and all hybrid-system components are available for inspection upon request. When inspected at the Chrysler dealership, technicians retrieved a diagnostic trouble code they acknowledged corresponds to the known wiring-connector short condition. This code was present before any recall procedures were performed. Safety Risk: I was traveling at highway speed with my family, the vehicle abruptly lost all motive power and began decelerating without my ability to maintain speed. I was forced to coast to the shoulder while surrounded by faster-moving traffic, exposing me and other motorists to the danger of a high-speed rear-end collision. Dealer Confirmation: The Chrysler dealer confirmed the presence of the wiring-connector-related fault code and agreed that it aligned with the recall defect pattern. However, they performed only the software update required under Recall 23V‑010 and informed me that they would not undertake further inspection or physical diagnosis unless I paid out-of-pocket, despite the safety-critical nature of the failure. They are ignoring the fact that the physical underlying defect is not fixed by the software update, much to my frustration. With this unfixed, the car is not safe to drive IMO. Inspection: The vehicle has been inspected by an authorized Chrysler dealer. No additional parties have inspected it. The dealer did not examine or repair the wiring harness or connector itself, refusing my request to do so. Warnings/Symptoms: A hybrid/electrical-system warning message appeared moments before the shutdown. No prior symptoms

The entertainment system when super cold outside the screen goes black and does not work. The issue has made it difficult then to change heating and cooling settings and utilize the rear view camera and other safety features of the car. The dealership was able to update it to fix it once then the other two times it came back on before the appointment for the dealership. The auto/stop start malfunctioned while waiting at light.putting my whole car in park and locked up until I turned it off and back on. This occurred twice and put me at risk with being on busy roads in the day. Dealership was able to fix with a new battery. In the past and currently the car has shifted with a Jerk or lunge type movement making the driver worried and concerned about hitting cars around them due to this. The dealership replaced a transmission gasket but still does this and have not been able to find the issue on 3 other occasions. The car also is now not shifting properly creating a low humming grind type sound when driving on the highway and the brake pedal feeling weird. This has delayed speeding up and slowing down creating major safety concerns when driving on the highway. The dealership has not been able to replicate yet due to only driving on town roads and not the highway at this time.
