2020 CHRYSLER PACIFICA — Problems, Recalls & Safety Data

This submission supplements my prior NHTSA 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.

WHILE DRIVING DOWN MAJOR HIGHWAY, THE POWER STEERING LIGHT WENT ON. IMMIDIATELY MY POWER STEERING SHUT OFF AND I COULD NOT TURN WHEEL AT ALL. HIGHWAY WAS 55 SPEED LIMIT AND I COULD NOT EVEN PULL OVER. HAD VAN TOWED TO DAYTON ANDREWS CHRYSLER DEALERSHIP FOR DIAGNOSIS AND THEY TOLD ME THAT THE POWER STEERING MECHANISM NEEDED TO BE REPLACED AND IT WAS GOING TO BE $4,500.00. THIS VAN HAS 14,400 MILES ON IT. AFTER LOOKING ON LINE IF OTHER PACIFICA OWNERS HAD THE SAME PROBLEM, IT SEEMED THIS IS A GLOBAL PROBLEM. I OBVIOUSLY CANNOT AFFORD TO FIX THIS ALMOST BRAND NEW VEHICLE AND THE SALESPERSON INDICATED THAT EVEN IF I DID WANT TO FIX THE PART IS ON BACKORDER AND THEY DON'T KNOW WHEN THEY COULD GET THEIR HANDS ON THE PART. THE FACT THAT THIS PART IS ON SUCH AN EXTREME BACKORDER TELLS ME THIS PART IS IN DEMAND BECAUSE MANY PEOPLE ARE HAVING THIS SAME ISSUE. PLEASE HELP ! i AM GOING TO CONTACT MY ATTORNEY TO SEE MY OPTIONS. THIS VEHICLE IS BASICALLY NEW AND FOR SAFETY REASONS, BEYOND ANY FAULT OF MY OWN, IS UNOPERABLE.

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.

The contact owns a 2020 Chrysler Pacifica. While the contact's wife was driving at an undisclosed speed, the engine seized in the middle of the road. The contact stated that there was no power to the vehicle. The contact stated that the failure occurred close to the residence, and there was not a lot of traffic. The driver was able to exit the vehicle and get to a safe area. The contact's brother-in-law was contacted for assistance; however, the driver became impatient waiting for assistance. The driver attempted to restart the vehicle, and the vehicle started. The help arrived, disconnected and reconnected the battery cables, and the vehicle was driven to the residence. The vehicle was not diagnosed or repaired by an independent mechanic or dealer; however, the dealer was made aware of the failure. The contact was informed that a recall was issued, but for Hybrid vehicles. In addition, the contact referenced an open investigation for the failure. The contact stated that the failure had occurred twice within two weeks. Additionally, the warning light that the “Auto START/STOP Unavailable” had remained illuminated since August 2025. The manufacturer was not made aware of the failure. The failure mileage was approximately 52,000. The VIN was unavailable.
