Service bulletin 37474

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 is a Technical Journal: DC Charging Power Limited to 150 kW. Vehicles equipped with the large HBAT27 (82?kWh) battery are capable of DC charging at up to 205?kW, provided certain conditions are met—such as a low State of Charge (<20% SoC) and active battery preconditioning (by selecting a DC charger in Google Maps at least 20 minutes before arrival).
