NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE22-008.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
On July 22, 2022, the Office of Defects Investigation (ODI) opened PE22008 to investigate allegation of loss of motive power, potentially due to transmission malfunction, in certain Chrysler Pacifica vehicles. In a January 17, 2023 letter to NHTSA, Fiat Chrysler Automobiles (FCA) submitted recall notice 23V-010 involving a transmission motor wiring defect in 67,118 model year (MY) 2017-2023 Chrysler Pacifica plug-in hybrid electric vehicles (PHEVs) manufactured from August 12, 2016 through January 9, 2023. FCA determined that an internal transmission connector short could result in an unexpected engine shutdown under certain conditions. Follow up correspondence with FCA confirmed this defect results in an electric motor position trouble code that was the basis for opening PE22008, therefore NHTSA is closing this investigation. The 23V-010 recall remedy is a software update to address the hardware failure associated with PE22008. When a hardware failure is detected, the vehicle limits motive power while instructing the driver to pull over to a safe location. NHTSA is concerned that drivers will pull over to an unsafe location when the warning message associated with the recall remedy displays on the dashboard. Due to the nature of the recall remedy and related reports, NHTSA has opened Recall Query RQ24004 to assess the recall remedy. The reports and failure report summary values included with this closing action are related to allegations of Recall 23V-010 remedy inadequacy. The Agency reserves the right to take additional action if warranted by future circumstances.

Vehicles and equipment listed for this investigation

What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
