GM has issued a Special Coverage bulletin for the 2016 through 2018 Chevy Volt, for an available fix for a battery energy control module malfunction.

Its ignition control module is failing. Since 2014 I have replaced it three times. Can you please tell why my control module keeps failing? It stops working without warning.

The HEI distributor is an inductive-discharge-style ignition, but with the points replaced by a solid-state switching device called an electronic ignition-control module.
