What can fail
Advanced diagnostic software may not have installed correctly during a previous repair. This can allow the high voltage battery to overheat and catch fire when charged to full or nearly full capacity.

Electrical system complaints dominate reports for the 2021 Bolt, with owners frequently describing high-voltage battery warning lights that return repeatedly even after dealer visits. Many describe the same warning cycling back across multiple service appointments, often affecting how the car drives or how much confidence owners have in its range and reliability. The propulsion system draws similar complaints, with owners reporting power-related warnings and reduced performance tied to the high-voltage system. A cluster of steering complaints also stands out: owners describe the steering rack binding progressively over time, the wheel refusing to return to center after turns, and occasional clunking from the front end over bumps. Several of these reports mention the condition worsening gradually and feeling unpredictable, with stiffness varying between driving sessions.

By System
The 2021 Chevrolet Bolt has 5 recalls, with two separate fire risks: the high-voltage battery can catch fire when charged to full or near-full capacity, and a prior repair attempt did not fully resolve the issue.
The battery fire risk persists on vehicles where an earlier software fix was applied, because the diagnostic software may not have installed correctly and can fail to detect defective battery modules. On the safety equipment side, there is a second fire concern: if the seatbelt pretensioner deploys in a crash, hot exhaust gases from the pretensioner can ignite carpet fibers near the B-pillar. A prior repair attempt for this pretensioner issue also did not fully resolve the problem on certain vehicles, leaving them still at risk of a post-crash fire inside the cabin.
