GM and LG identify cause of battery fires in Bolts; recall for MY2017-2019 vehicles.
As part of GM’s commitment to safety, experts from GM and LG have identified the simultaneous presence of two rare manufacturing defects in the same battery cell as the root cause of battery fires in certain Chevrolet Bolt EVs. As a result, GM will be conducting a new recall for the previous population of Bolt EVs (2017-2019) to address the risk of battery fires in these vehicles.
As part of this recall, GM will replace defective battery modules in the recall population. We will notify customers when replacement parts are ready. While we prepare to conduct this recall, we are asking customers to take the following steps until the new remedy has been performed:
- Customers should, whether or not they received the current software update, return their vehicle to the 90% state of charge limitation using Hilltop Reserve mode (for 2017-2018 model years) or Target Charge Level (for 2019 model year) mode. If customers are unable to successfully make these changes, or do not feel comfortable making these changes, we are asking them to visit their dealer to have these adjustments completed.
- Additionally, we ask that customers charge their vehicle after each use and avoid depleting their battery below approximately 70 miles of remaining range, where possible.
- Out of an abundance of caution, customers should continue to park their vehicles outside immediately after charging and not leave their vehicles charging overnight.
In the meantime, customers who have not visited their dealer to receive the advanced diagnostics software should visit their nearest Chevrolet EV dealer to obtain the update. After obtaining the software, customers should still limit their state of charge to 90% and otherwise follow the advice above.
