Official summary
TECHNICAL SERVICE BULLETIN: VCU SOFTWARE LOGIC UPGRADE (SA541) - This bulletin provides information to upgrade the software logic of the Vehicle Control Unit (VCU) on certain 2023MY EV6 GT (CV GT) vehicles produced from August 25, 2022 through July 20, 2023, to optimize the brake lamp ON/OFF logic to prevent momentary activation and deactivation of the brake lights when regenerative braking is in use while driving over uneven road surfaces (e.g. railroad crossings, raised pavement markers). This condition does not affect brake light activation when the brake pedal is depressed.

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.
