Service bulletin TSB-0425-01
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
Bulletin Title: Update the Vehicle Control Unit (VCU), Thermal Control Unit (TCU), and Telematics Module Unit (TMU) software to the latest version. Symptom: The existing VCU and TCU software may cause various fault codes to be stored in the vehicle's fault memory. The TMU does not currently support WiFi connection capability. Discussion: If equipped, the updated VCU software adds ePTO enhancements, improvements to 12V and high-voltage battery conditioning, and eliminates erroneously stored faults. The TCU software improves the thermal management system and eliminates erroneously stored faults. The TMU software adds WiFi connection capability to the vehicle.
