Chevy Says They Have A More Permanent Fix to Prevent Bolt Battery Fires

Chevy says battery scans and software update will allow 2017-2019 Bolt owners to once again charge their batteries to full capacity. The EVs were recalled last November following reports of the batteries catching on fire while charging near 100%. As a temporary measure, owners were asked to limit their battery's charging capacity to 90% until a more permanent fix could be found.

That permanent fix is a diagnostic scan by dealers to look for potential battery anamolies and a software update that can detect potential issues related to changes in battery module performance before they become potential problems.
