Experts from GM and LG have identified the simultaneous presence of two 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 new recall, GM will replace defective battery modules in the recall population.
