Service bulletin TSB-0625-02
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
The updated VCU software includes enhancements for 12V and high-voltage battery conditioning, as well as resolving issues with incorrectly stored faults. The revised TCU software enhances the thermal management system and eliminates erroneously stored faults. The updated OTA software enables TCU and BMS diagnostics to be reported over the air. Additionally, the improved BMS software enhances fault detection and decreases the overall time required for cell balancing.
