Chevrolet Bolt EV front brake caliper can crack

high How serious is it? About this label

A caliper that breaks during hard braking can cut your braking power with little warning and lead to a crash, so treat it seriously; the notice does not tell owners to stop driving before the free inspection.

What's wrong, in plain English

Some 2020 Bolt EVs have a front left brake caliper — the part that presses the brake pads to slow the wheel — that was poorly made. If you brake hard, it can crack. A cracked caliper can let brake fluid escape, and losing fluid means the brakes may not stop the car as well as they should. A dealer will check the lot number stamped on that caliper and put in a new one if yours is affected.

What you should do

1. Enter your VIN at nhtsa.gov/recalls to see if your Bolt EV is included.
2. Call your Chevrolet dealer or Chevrolet customer service at 1-800-222-1020 and mention recall N202321400.
3. Have the front left caliper inspected, and replaced if needed, free of charge.
