What's wrong?
The front left brake caliper on the 2020 Chevrolet Bolt EV is the metal clamp in the disc brake system. When you press the brake pedal, hydraulic pressure moves the caliper so the brake pads squeeze the rotor and slow that wheel. The caliper has to stay solid while that pressure rises during hard braking.
On affected Bolt EV vehicles, the iron used for the caliper was not properly treated before the supplier cast the part. That weak casting can fracture during a high-pressure braking event. A fractured caliper no longer holds the brake pads in the intended position, so braking at that wheel is compromised.
There is no warning sign before failure. The recall file does not identify a driver-noticeable symptom before the caliper fractures, so do not rely on pedal feel, noise, or a dashboard light to tell you the part is safe.

Not every 2020 Chevrolet Bolt EV hatchback is on the list. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
A fractured front left brake caliper can leak brake fluid, reducing brake performance and increasing the risk of a crash. If your VIN is included, contact a Chevrolet dealer about inspection timing, leave extra following distance, and brake early. Repair will be free at any franchised Chevrolet dealer once available.
What should I do?
- Check your VIN to confirm your 2020 Chevrolet Bolt EV is included in this recall.
- Wait for Chevrolet's owner notice before scheduling the final dealer remedy.
- Contact a franchised Chevrolet dealer and reference recall number 20V808 when asking about the free front-left brake-caliper inspection and replacement that addresses the caliper fracture and brake-fluid-loss risk.
- Bring Chevrolet's recall notice if you received one, and ask the dealer to confirm GM recall N202321400.
- Drive cautiously until the vehicle is inspected. Leave extra following distance and avoid hard braking when traffic allows.
What happens at the repair
The listed remedy is still marked as under development, so do not assume the final dealer repair can be scheduled until Chevrolet opens it. At the dealer, a Chevrolet technician will inspect the casting lot number on the front left brake caliper and replace the caliper if the lot number shows it is covered. The final dealer repair will be free once available. Out of pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because all covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.
