GM to address rare Chevy Bolt EV battery fires with new diagnostics

Rather than replace the errant batteries (apparently problem may only affect some vehicles or scenarios), GM dealers will install a new diagnostic system that monitors the battery pack and issues a warning to have it serviced, before it becomes a critical failure.

The software will monitor for potential battery problems and alert owners before they become an issue.
