Common Issues and Problems with the Used Chevrolet Bolt EV

First Generation (Bolt EV: 2017 - 2023)

Drive Battery Failure & Safety Recall

The most significant issue for early Chevrolet Bolt EV models (2017 - 2022) was the high-voltage drive battery. Manufacturing defects in LG cells (torn anode tabs, folded separators) created a risk of thermal events. GM launched a massive recall (N212345990), replacing battery modules with updated chemistry and improved quality control.

Buyer Tip: Always verify the VIN to confirm the battery replacement recall has been completed. Vehicles with the new 66 kWh pack are considered safe and more reliable.

DC Fast Charging Limitations & Onboard Charger Issues

The Bolt EV’s DC fast charging is capped at ~50-55 kW, slower than newer EVs, leading to longer charging times on trips. Owners also reported Level 2 onboard charger faults in 2017-2018 models, sometimes requiring replacement.

Buyer Tip: Slow DC charging is a hardware limitation. For AC charger faults, dealer service is required, usually covered under the 8‑year/100,000‑mile EV warranty.

12V Auxiliary Battery Drain

Like many EVs, the Bolt EV can suffer from 12V battery drain if left unused or if electronics fail to enter sleep mode. A drained 12V battery prevents the car from starting, even with a full drive battery.

Buyer Tip: Replace the 12V battery every 3-5 years. Persistent drain may require dealer diagnosis for parasitic draws or software bugs.

Infotainment & Electronics Glitches

Pre‑facelift Bolts (2017 - 2021) often show infotainment freezes, lagging, or blank screens. Owners also reported camera failures(backup and forward-facing) and brake actuator tapping noisesin some 2020 models.

Buyer Tip: A soft reset (holding Home + Fast‑Forward buttons) can fix temporary freezes. Ensure dealer software updates are installed. Hardware failures of screens or cameras may require replacement under warranty.

Conclusion

The Chevrolet Bolt EV offers strong value and range, but buyers must confirm the battery recallwas completed. Other issues-slow DC charging, 12V battery drain, infotainment glitches-are less severe but worth checking. With the recall resolved, owner feedback shows the Bolt EV is a reliable used EV option, provided buyers are aware of these common points.
