Official summary
The purpose of this EI is for specific Bolt EVs that have been selected for an engineering investigation. The customers involved will be contacted proactively by GM to visit a Chevrolet Bolt EV certified dealer for a battery pack replacement under warranty.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
