NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE23-012.
try.vin does not copy NHTSA's investigation documents; NHTSA's investigation record lists the ones NHTSA has published.
On July 3, 2023, the Office of Defect Investigation (ODI) opened PE23012 to investigate allegations of loss of motor power on model year (MY) 2022 Kia EV6 vehicles. Some consumers reported loss of motor power immediately after warning lamp illumination or reduction of motive power while the vehicle was in motion. This investigation found that the Integrated Charing Unit (ICCU) may become damaged over time from transient high voltage and thermal cycling. A damaged ICCU may not be able to charge the 12-volt battery which can discharge gradually while driving with a reduction of motive power. The vehicle could eventually experience a complete loss of motive power thereby increasing the risk of a crash. On July 13, 2023, Kia conducted a service campaign to inspect the ICCU and install an improved over-current detection software logic in certain 2022-2023 EV6 vehicles. On March 15, 2024, Kia filed recall 24V-200 for 48,232 MY 2022-2024 Kia EV6 vehicles. The recall remedy provides an inspection of the ICCU, and if necessary, a replacement of the ICCU and the associated fuse. The ICCU software reduces the risk of overcurrent and implements voltage peak reduction at the end of EV battery charging. The recall also includes a software update that revises the electric water pump operational threshold to reduce thermal loading during charging and driving. In view of the recall action being taken by Kia, ODI is closing this Preliminary Evaluation. The agency reserves the right to take additional action if warranted by future circumstances.

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.
