Service bulletin PIP6122B
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
This information addresses a potential software anomaly that may cause a MIL illumination, a Service High Voltage message on the IPC, and, when the DTC is current, a no-start condition while the vehicle is in Run/Propulsion mode. If one or more of the listed DTCs are stored in history, technicians are to perform SPS2 Hybrid/EV Battery Data Retrieval per Bulletin 25-NA-044, create a TAC case referencing the applicable P.I. number, and include the WCC obtained from the SPS data retrieval. TAC will provide further direction after engineering reviews the vehicle-specific data. This information applies only to the listed DTCs and symptom bytes and does not apply if the codes or symptom bytes differ.
The document
The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.

Listing a model year does not mean every vehicle of it is concerned: the document says which.
