2021 Chevrolet Bolt EV Check Engine Light Codes

The diagnostic codes that illuminate the check engine light on a 2021 Chevrolet Bolt EV range from simple sensor alerts to battery management and charging-system faults. At Herb Chambers Chevrolet in MA we commonly see codes related to the battery management system (BMS), high-voltage charging interruptions, and temperature or sensor inconsistencies. Left unaddressed, BMS warnings can lead to reduced range, degraded battery capacity, or unexpected charging failures—costs that grow quickly if a minor sensor issue becomes a full battery replacement. Our certified technicians use Chevrolet OEM diagnostic tools to identify the exact code and recommend the most efficient repair path. Repair costs vary by the repair: sensor replacement or software reflash can often be resolved affordably and the immediate cost is typically far lower than eventual battery replacement. Choosing dealership service delivers long-term savings because accurate diagnostics avoid unnecessary parts replacement and preserve the vehicle’s warranty and resale value. We combine transparent pricing, factory-trained techs, and quick turnarounds to keep your Bolt EV on the road. To book a check now, schedule service or check our service specials for current offers.
