# Service bulletin 122\-G6X5S\-04

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.

- Type: Service bulletin
- NHTSA id: 10134863
- Published by NHTSA: 2018\-04\-23
- Manufacturer's number: 122\-G6X5S\-04
- Manufacturer's date: 2018\-03\-19
- NHTSA component: ELECTRICAL SYSTEM

## NHTSA's summary

Subject: Control unit for high\-voltage charger Information: Due to a software error, there is a possibility that the control unit for the high\-voltage charger will not switch to energy\-savingmode after the vehicle is stopped in the event of specific user behavior. This can result in an increased closed\-circuit current load and can thus deplete the vehicle electrical system battery.
