A condition exists that may require the vehicle to be taken in for service.

Summarized in our own words from the 2023 Chevrolet Bolt EUV owner's manual (AI-assisted; every light name was matched against its cited page 2026-10-18). Your vehicle may not have every light, and other years can differ. A red warning that stays on usually means stop safely and check: your manual has the final word.
