Service bulletin SS1034864

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

Service Solution for eB2 Product Updates & Enhancements. Certain early production eB2 buses may complain of an intermittent amber colored battery light flickering or illuminating for no reason. A new software update for the EV controller has been developed to correct this issue. Additionally, durability testing has determined that a crack could form in the coolant pump mounting bracket. A reinforcement brace has been designed to reduce the risk of this crack forming.
