Service bulletin B612523

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 purpose of this Service Bulletin (SIB) is informational regarding DC (direct current) charging complaints on Gen 5 Battery Electric Vehicles (BEV). It serves as a supporting argument and is intended to help distinguish between a standard designed function or component operation from an actual system fault in a DC charging customer complaint (i.e., “DC Not charging or “DC charging too slow”. Helpful “Tips and Tricks” have been included on each topic within the document that can be used as reference to aid in the diagnosis or in understanding the system. The situation involves several possible causes: 1. Limitation of charging power by the charging station or charging app configuration. 2. Decreasing charging power at a very high state of charge (SoC). 3. Too frequent DC charging attempts within a short period of time. 4. The high-voltage battery is not at the ideal temperature. 5. Ageing of the high-voltage battery.
